Definitions
- the invention relates to a method and a plant for the purification of industrial gases from solid and liquid particles contained therein, such as those found in industry, for example in waste incineration, metallurgy, chemistry.
- Filtering out gas is an acute practical problem.
- the low effectiveness of gas cleaning with current facilities is unsatisfactory.
- the dedusting of gases from submicron particles requires high gas speeds, which is often done with cyclones - these are vortices in which the centrifugal force is used - and is associated with high energy consumption.
- electrostatic precipitators the number of electric fields or the length of the high-voltage electrodes or the grounded electrodes must be increased. This increases the energy consumption for the electrostatic charge of the particles, but also the size of the gas cleaning system.
- wet separators the accumulation of submicron particles means an increase in the spray liquid volume and requires a high relative speed between the water drops and the gas flow.
- micropore filters such as ceramics, filter bags / bags, etc. are used to collect the submicron particles (see US Pat. No. 4,029,482, US Pat. No. 3,999,964).
- the effectiveness of most of these plants is limited by the low speed of the gas flow.
- the collection of submicron particles also leads to a high pressure drop, which keeps energy consumption high. Is also Periodic or continuous cleaning of the filters by means of pneumatic pulses or washing out necessary.
- the collection of submicron particles can be improved by saturating the gas with water vapor.
- the water vapor condensation on particles, particle charge in an electrical field and their discharge by the gas stream is described, for example, in US Pat. No. 4,222,748 or FR 2,483,259 or DE 2,235,531 or CA 2,001,990.
- Ionizers are also used for the electrical charge of particles. However, this requires several ionization devices, which makes the gas cleaning system complex. The high-voltage ionizers require large amounts of compressed air and thus drive up energy consumption.
- water-flushed filters or absorbers uses large amounts of water for spraying and increases the pressure drop in the gas cleaning system.
- the invention has for its object to provide a system for gas cleaning with which the cleaning process can be carried out with significantly improved efficiency.
- the object is achieved by a gas cleaning system according to the features of claim 1 and a method carried out with it according to the method steps of claim VI.
- the system consists of three connected assemblies, which are installed in a technically expedient place in the gas line, in the direction of flow of the gas: the first, the first pipe section 1, in which the electrostatic charging unit / group for generating a corona discharge is located and forms a space charge region in the adjoining room, from which essentially the particles of the same name are pushed onto the inner wall of the tube section 1 via thermal movement and charge repulsion and neutralized there,
- the electrostatic charging unit installed in the first pipe section 1 is constructed as follows in the flow direction: around the circumference, along the inner wall of the gas line, there is first a collector 110 for collecting the condensate flowing down the inner wall of the gas line. Then comes the grounded electrode, which extends over the clear cross section of the gas line, in the form of a plate which, evenly distributed over the cross section, has perforations / nozzles parallel to the axis of the gas line. Each nozzle tapers conically in the flow direction over the plate thickness then steadily into a ring area and then widens conically with a steady transition.
- a high-voltage electrode grid 112 on which are seated electrodes 113 which face the direction of flow, all of which have a free, tapering end and each protrude into one of the nozzles.
- the electrodes can be individually adjusted axially, ie parallel to the axis of the associated tube section, and on the other hand, overall laterally and axially with the grid 112.
- the high-voltage grid 112 is held in position by at least one feedthrough.
- the group of grounded electrodes 212 installed in the second pipe section 2 is constructed as follows:
- the group of grounded electrodes 212 is a bundle of tubes, the longitudinal axes of which lie parallel to the axis of the tube section 2 and fill it. They are made of electrically conductive or non-conductive, but gas-inert material. The tubes do not touch each other. They are held in position and at a distance from each other by means of perforated plates on both ends and at least one in between. This tube package is directly covered by the pipe section 2.
- the hole structure of the two end plates corresponds to the cross section of the tube bundle.
- the holes in the end plates each have the inside width of the tubes.
- the at least one plate in between has the same hole structure, but the holes have a clear width from the outside diameter of the pipes.
- this perforated plate lying in between or these perforated plates lying in between have an area at their edge with which they do not rest against the inner tube wall 2, so that a coherent chamber system thereby exists.
- the two external chambers are each connected to a coolant circuit via a connecting piece in the wall of the pipe section 2. So the tube package can be cooled, without the coolant being able to come into contact with the gas, which is still particulate.
- the tube bundle 212 stands with its downstream end on an electrically conductive support or grid 211, which is or is attached to the wall of the tube section 2 in an electrically conductive manner via a ring bracket 210.
- a spray head 220 which is attached with its spray axis on the axis of the pipe 2 there, at least at a distance the following group of grounded electrodes 212 covering the cross section, that during periodic spraying the exposed forehead of the electrode arrangement is completely covered by the spray cone made of water.
- the inner wall of the tubes 212 is rinsed, deposited particles are washed off and, due to the moisture / wetness and the usable electrical conductivity that occurs, are electrically neutralized and partially discharged via the outlet connection piece 232.
- the unit for filtering the gas flowing through is installed in the third pipe section 3 which follows downstream. In it is first a pipe that goes from the wall of the pipe section 3 to the axis and then kinks in the direction of the current and protrudes on the axis into the cylindrical space surrounding the filter. This axial tube part passes through a cover 311, which sits on the gas flow-facing end of the filter and prevents the gas flow from entering the interior of the filter unfiltered. At least one spray head 322 is located in the end region of the pipeline for spraying the entire inner wall of the cylindrical filter device.
- the filter cover 311, 312 consists of two concentric parts and, when assembled, forms an annular trough 324, the opening ring of which faces the gas flow. Drip water is collected in this tub from the pipe section 2 located upstream in front of it and discharged via a connection piece 319.
- the filter device consists of a tubular frame / housing / cage (323), around which a porous material 310 as the actual filter is placed in a jacket-like manner in at least one position.
- the filter device sits with its flow-facing forehead on an annular bracket 314 fastened to the wall of the tube section 3, which at the same time as the wall of the tube section 3 forms an annular trough for collecting part of the spray water 320, which is connected to the wall of the tube section via connecting pieces 317 3 is derived.
- the gas mixed with particles must therefore pass through the filter, which is clamped with its cover between the console 314 facing away from the flow and a console 313 facing the flow.
- the gas forced through the filter and freed from particles passes as purified gas through the annular console into the downstream environment.
- the package consists of grounded electrodes (212) also of electrically conductive or electrically non-conductive material, but then only of a bundle of parallel tubes 212 which at most fill the cross section of the tube section 2 and which are disordered, that is to say touching or not .
- This tube package stands on the grounded support / grid 211 and is anchored in position there.
- the individual tube walls are now flowed on both sides, ie the gas still to be cleaned therein flows through the individual tube and past it on the outside.
- the storage area for the particles and their electrical neutralization thereon is therefore considerable, in the best case, when they are not in contact with one another, twice as large as in the construction of the tube section 2 according to claim 1.
- No coolant flows between the tubes 212 since there are no chambers for separate flow, so it is not cooled.
- the tubes are not mechanically loaded differently on the outside and inside, so they can be kept extremely thin. It is sufficient if the wall thickness d Ws of a tube 212 is kept in the range 0.01 D 2 ⁇ 0.1 D 2 with respect to its diameter D 2 .
- the high-voltage grid 112 is connected to a high-voltage source via a feed-through 117 or more than one feed-through 117, which is distributed uniformly around the circumference of the pipe section 1 (claim 3).
- a passage gas or all can also be flowed through with a sealing gas 116 to maintain the insulation strength (claim 4).
- the surface of the tubes 212 from the set of grounded electrodes 212 is enlarged on the outside and / or inside (claim 5), on the one hand to cool more effectively and on the other hand to have more storage space on the inside (claims 6 and 7).
- a spiral device is installed in the tubes, which causes the flowing gas to spiral forces what are generated by centrifugal forces (claim 8).
- the wastewater at the bottom of the grounded electrodes via the carrier there is also diverted and fed to cleaning (claim 9), as is the wastewater collected via the filter cover and the annular bracket at the bottom of the filter, which is more massive.
- the method according to claim 10 proceeds according to the following steps:
- the gas Before the gas is introduced into the device, it is cooled and saturated with water vapor.
- the gas stream 4 is forced past a condensate collector 110 through a grounded plate (111) provided with nozzles, each with a narrow center piece, in order to then flow into a conically opening outlet area of the nozzle, into an electrode gap, which consists of the respective nozzle outlet and one protruding high-voltage electrode tip (122) is formed, in which aerosol particles are electrostatically charged.
- a condensate collector 110 through a grounded plate (111) provided with nozzles, each with a narrow center piece, in order to then flow into a conically opening outlet area of the nozzle, into an electrode gap, which consists of the respective nozzle outlet and one protruding high-voltage electrode tip (122) is formed, in which aerosol particles are electrostatically charged.
- Some of the electrically charged aerosol particles from the gas stream are discharged under the action of a space discharge in the wider area of the gas stream by electrostatic repulsion between the electrically charged particles and the charged aerosol deposit on the inner walls of this area.
- the gas stream is passed through a system of hollow, earthed electrodes with the simultaneous deposition of charged aerosols on the surface of the earthed electrodes which is in contact with the gas stream. Then the gas flow in the ring area between a tubular filter device and the wall of the Pressed gas line through the filter made of a porous material, wherein the charged particles are more or less completely deposited in the filter material depending on the filter material.
- the gas cleaned in this way is then discharged into the downstream environment.
- the filter device is washed continuously or periodically by spraying from the spray heads inside, ie the particles deposited in the filter fabric are flushed out with the spray water.
- the gas stream flowing through the bundle of tubes is cooled by a coolant flowing through the space between the tubes, and the charged particles which are deposited on the respective inner wall of the tube are discharged from the end facing the current through periodic irrigation of the inner walls of the bundle of tubes. Due to the fact that the gas flow in the grounded tubes is given a twist or rotation by the built-in spiral device, the particles that are still entrained are additionally pushed outwards by centrifugal forces and thus to the inner wall, and the incoming particles are electrically neutralized and washed away (Claim 13).
- Effective gas cleaning is achieved with a low pressure drop, low energy consumption for the electrostatic charge, without continuous spraying of water for cleaning the grounded electrodes, with continuous spraying being readily adjustable.
- the modular construction principle of the device and the small size allow it to be used to expand existing gas cleaning systems and to make the gas cleaning tendency to expand to submicron particles.
- the components are made of light and corrosion-resistant materials with regard to the gas to be cleaned.
- the grounded electrode / plate with its nozzles evenly distributed over the end face, each with a conically tapering gas inlet and a conically widening gas outlet, produces the effect of saturated gas acceleration and expansion with water condensation, which increases the size and number of charged particles with less mobility. This then leads to the zone of the space charge with a high charge volume density and ensures the discharge of particles through the further gas flow at the grounded components of the system.
- the system is modular
- the system has small dimensions and light weight
- the components are made of raw / uncleaned gas made of corrosion-resistant materials;
- FIG. 1 the overall view in section
- FIG. 2 the pipe section with charging device
- FIG. 3 the perforations / nozzles in the grounded electrode
- FIG. 4 the high voltage electrodes in the charging device
- FIG. 5 the pipe section with grounded hollow electrodes in two designs
- FIG. 6 shows the example of a grounded electrode
- FIG. 7 shows the experimentally determined courses of the concentration distribution of the particles at the entrance and at the exit.
- the flow-facing end face of the tube bundle 212 has a distance of 1.5 to 5 times the diameter D of the grounded electrodes from the high-voltage electrode 112 of the charging unit.
- D the clear width of the gas line 1 or 2 or 3, the gas line with the gas to be cleaned in general, is in a size range which, with the raw gas volume flow divided by the area corresponding to D, has a gas velocity between 0.1 and 10 m / sec, advantageously between 0.5 and 2 m / sec. This is known from gas flow technology. Therefore, the dimension is determined according to the seizure and the flow rate.
- the length of the grounded electrodes 212, the tubes 212 is derived from the decisive parameter D as follows:
- the plant for the electrostatic cleaning of gas / gas consists of the first pipe section 1 with the electrostatic charging unit 1 in the flow direction, and the subsequent pipe section 2 with the Group of grounded electrodes 212, which consists of a bundle of tubes 212, and finally the third tube section 3 with the filter device.
- the gas flow is indicated by the arrow 4 at the beginning of the first pipe section 1 for the entry of the contaminated raw gas and the arrow 5 for the exit of the cleaned gas at the outlet of the third pipe section.
- the pipe sections 1 to 3 have, for example, a circular cross section, but the system can also be realized with a rectangular cross section.
- the annular collector 110 is located on the inner wall at the entrance to the system for collecting the condensate water running down the pipeline supply line and thus for protecting the subsequent electrostatic charging unit. This collected condensate water is discharged via the nozzle 118 for reprocessing.
- the grounded electrode 111 of the charging unit 1 is a plate 111 which covers the clear width of the tube section 1 and is made of electrically conductive material, such as graphite or corrosion-resistant, mechanically suitable metal such as stainless steel.
- the plate has the following structure across the cross section of the pipe section 1, as seen in the direction of flow:
- the number of nozzles and their diameters depend on the conditions of the technical process, the volume of the gas to be cleaned, the conditions for the effective loading of the aerosol and the minimum pressure drop charge unit 1. Other nozzle shapes, if at least similarly powerful, are also suitable.
- the grid 112 which can be subjected to high voltage, adjoins, extending over the cross section of the pipe section 1. It is held via the bushing 115 or bushings 115 which are uniformly distributed around the circumference and by means of which the grille 112 can be laterally adjusted within limits.
- One of the bushings serves as a high-voltage connection between the power supply unit (not shown) outside and the grid 112. All bushings 115 are flowed with sealing gas 116 via the connecting piece 11 in order to have electrically defined conditions at the passage of the bushings into the interior. This sealing gas 116 is usually temperature-controlled, but does not have to be mandatory in the construction of the system.
- the high-voltage grid 112 is as coarse-meshed as possible and therefore at least nodes in the structure of the nozzle arrangement in the grounded base plate 111, on these nodes corresponding to the nozzles, the electrodes 122 are screwed and protrude from the gas flow.
- An electrode 113 projects with its free tip 122 into the outlet 121 of a nozzle.
- the electrode grid 112 together with the attached electrodes 113 can be adjusted / adjusted axially and laterally (see FIGS. 1 to 4). This determines the level of the pre-discharge voltage and the current density in the area of the electrode gap where the particle charge takes place.
- the maximum current density with a minimally applied high voltage is related to the position of the tips 122 of the electrodes 113 in the critical cross section of the nozzles.
- the axial position of the electrode tip 122 in the conical outlet 121 of the nozzle can be individually adjusted (see FIG. 2).
- Downstream of the electrode grid 112 is the space charge volume formed by the ionized particles / aerosols, which is formed by the high-voltage grid 112 up to that protruding from the wall of the pipe section 2
- Wall extends in its length.
- the tube section 2 with the grounded electrodes 212 from the bundle of tubes is installed downstream of the grid 112 at a distance of 1.5 to 5 D, D the clear diameter of the gas line 1/2 / 3 and the characteristic dimension parameter of the grounded electrode 111 explained above.
- An example of the arrangement of the grounded tube bundle 212 is shown in FIG. 5 below.
- the inside diameter of the tubes 212 is such that a laminar gas flow occurs in them.
- the tubes 212 as well as the walls of the pipe sections 1 to 3 can be made of conductive, such as graphite or process-inert stainless steel, VA, or non-conductive material, such as PP, PVC, PVDF, GFK, they can be rigid or flexible.
- the number and diameter of the tube electrodes 212 depends on the conditions to ensure effective sedimentation of the charged particles on the electrode inner walls 212 and to maintain a minimum pressure drop in the tube arrangement.
- the bundle of tubes 212 is clamped between two perforated plates 213, the holes of which have the inside width of the tubes 212, in such a way that there is a free passage through each tube 212.
- the tube bundle 212 through three further perforated plates 222, the holes of which have a clear width equal to the outside diameter of the tubes 212.
- the three perforated plates 222 are positioned equidistantly between the two outer perforated plates and have an indentation at one point of the edge area, so that a chamber system is formed between the two outer perforated plates 213, through which coolant can flow through in a meandering manner.
- the two outer chambers each have a connection piece 215 and 217 in the wall of the tube section 2, through which the coolant flows out. is let in and absorbs heat from the outer wall of the tubes 212.
- This cooling increases the effectiveness of gas cleaning. If gas, for example air with ambient temperature, is used as the cooling medium 214, the warmer exhaust air 216 can be used as insulation air / sealing gas.
- the tube bundle 212 with the perforated plates 213 and 222 is seated with its forehead facing away from the flow on the carrier 211, which here consists of a grid of fabric-like metallic wires. This entire device is at ground potential or is grounded.
- the gas flow is forced to rotate. It is forced here by the spiral 229 built into each tube 212 to make a spiral movement (see FIG. 6).
- the spirals 229 are each held axially here by a rod 230.
- the spray head 220 is installed within the gas duct between the charging group 1 and the group 2 of the grounded electrodes 212.
- the spray head is installed in such a way that the spray water cone completely covers the flow-facing end of the tube bundle 212 or the perforated plate 213 there.
- the intermittent or periodic spraying of water reduces the gas temperature, ensures the humidification and cleaning of the inner surface of the grounded tubes 212 and thus improves the collection of charged aerosol particles.
- the water for spraying is fed through the line to the nozzle 219, at the end of which the spray head 220 is mounted. Of course, you can also spray continuously.
- the arrangement 1, on the left in FIG. 5, shows the structure of the device for the post-purification of the gas without cooling the tube packet, because there are no flow chambers as in arrangement 2. but the tubes on both sides are flown inside and outside by the gas to be cleaned coming from the space charge zone, and the remaining charged particles are largely completely deposited and electrically neutralized.
- the tubes 212 can touch.
- the tubes should not touch each other due to the necessary design of flow chambers with flow around them, at best they can come very close, so that they are always surrounded by coolant.
- the filter device is installed downstream in the pipe section 3.
- the actual filter material 310 is made of porous material, which encases the tubular, electrically conductive grid housing in the shape of a hollow cylinder.
- the outer diameter of the filter cage 323 is smaller than the inner diameter of the wall of the pipe section 3, so that there is an annular space.
- the centrally open filter cover 311, which forms an annular trough 324, sits flush on the flow-facing end of the grid housing 323 together with the porous filter material 310.
- the filter cover 311 is closed centrally with the cover 312, through which the water pipe coming from the connection piece 321 in the wall of the pipe section 3 passes centrally. Dripping water from the gas stream and from the grating 211 is collected therein and drained off via the connection piece 319 present evenly around the circumference of the pipe section 3.
- the filter cage 323 together with the filter jacket 310 stands on the ring 315 and with this in the ring pan formed by the annular bracket 314 on the side facing away from the flow at the outlet of the pipe section 3, along the inner wall and the inner wall.
- This filter structure in the pipe section 3 forces the gas flow to pass only through the ring-shaped to pass through the filter jacket 310 and unload its collected particles therein, in order to then emerge cleanly from the inside of the grille housing and exit centrally through the annular console at the exit.
- the water emerging via the spray heads in the end region of the line running on the axis sprinkles the inner wall of the filter and rinses out the particles deposited therein, which are collected as filtrate in the annular trough. This filtrate is discharged through the filtrate outlet 317.
- the filter housing 323 can be cylindrical, rectangular. Other geometries can also be used as long as they do not impair effectiveness.
- the device for electrostatically cleaning the gas from liquid and / or solid submicron particles can be supplied by the device for cleaning and the re-introduced use of the cleaned, collected waste water.
- the wastewater treatment facility includes standard procedures and equipment. It is not shown in Figure 1.
- the gas line can have an annular or rectangular cross section. Another geometry is also possible, as long as it allows the function in this effectiveness.
