Description
Technical field
What the present invention relates to is a kind of charge air flow even distribution device that is exclusively used in absorber, especially a kind of interior charge air flow even distribution device of the horizontal absorber of air separation plant that is applied to the cryogenics field.
Background technology
The air cryogenic refrigeration is produced in oxygen or the nitrogen process, need utilize adsorbent that air is carried out adsorption treatment, impurity such as moisture that is contained in the removal air and carbon dioxide.Adsorption treatment is the inside that adsorbent is placed on absorber, and when requiring the adsorption gas flow process adsorbent bed in the adsorption treatment process, flow velocity is even, and adsorbent maintains static.Because entering the adsorption gas flow of horizontal absorber inside is radial air inlet, after the cross direction profiles, pass the adsorbent bed of parallel and the cylindrical shell longitudinal axis, at air inlet the buffer board structure is set usually, because air-flow velocity is bigger in the pipeline, airflow kinetic energy ρ v
2Quite big.For long horizontal absorber, the adsorption gas flow flow velocity of import regional area and the flow velocity difference at absorber both ends are very big; The import regional area is subjected to the impact of air-flow easily, cause local bed fluidisation attitude, and some position flow velocity is little.Therefore some local adsorbent has adsorbed changes effect, and some local very big surplus in addition makes adsorbent can not obtain fine utilization, and the waste adsorbent has influenced effective use of product, has also wasted the renewable sources of energy.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of air inlet that is arranged on horizontal absorber specially, evenly distribute at whole bed surface with steering current, can effectively improve the utilization rate of whole adsorbent, reduce the use amount of adsorbent, the airflow uniform distribution device of the horizontal absorber that reduces cost.
The objective of the invention is to finish by following technical solution, it includes at least one interior air inlet pipe that connects the external admission pipe, should interior air inlet pipe be connected with the water conservancy diversion area under control that constitutes by at least one mozzle, be provided with the antipriming pipe of controlling according to air velocity in the back of mozzle, connect end plate behind this antipriming pipe, antipriming pipe is installed on the air inlet of horizontal absorber by support member.
Described antipriming pipe is the long tube-shaped tube of arranging along horizontal absorber cylindrical shell axial direction of circle, and diameter is at φ 300-φ 2000mm, and the percent opening on the tube wall of antipriming pipe is at 10-70%.
About described antipriming pipe is at least two, and be connected to mutually respectively on the mozzle in mozzle district.Not perforate or have a small amount of hole on the tube wall of described mozzle, as perforate, then percent opening is between≤30%.
Described mozzle and antipriming pipe are to be made into integration with same pipe, or the multistage pipe is weldingly connected.Described antipriming pipe also can surround the last layer silk screen outward, and the screen opening rate is at 10-70%.
The present invention is the air inlet setting at horizontal absorber, comes down to a kind of airflow uniform distribution device, and it can evenly distribute at whole bed surface by steering current, can effectively improve the utilization rate of whole adsorbent, reduce the use amount of adsorbent, reduce cost, and convenient maintenance, energy savings.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing, the present invention mainly includes at least one interior air inlet pipe 1 that connects the external admission pipe, should interior air inlet pipe 1 be connected with the water conservancy diversion area under control 2 that constitutes by at least one mozzle, be provided with the antipriming pipe of controlling according to air velocity 3 in the back of mozzle, be connected to end plate 4 (form or flat cover or end socket) behind this antipriming pipe 3, and be installed on the airflow inlet of horizontal absorber by bracing or strutting arrangement.
Described antipriming pipe 3 is the long tube-shaped tube of arranging along horizontal absorber cylindrical shell axial direction of circle, and diameter requires the antipriming pipe perforate at φ 300-φ 2000mm, and the percent opening on antipriming pipe 3 tube walls makes air communication cross the flow velocity of antipriming pipe less than 3m/s at 10-70%.About described antipriming pipe 3 is at least two, and be connected on the mozzle in water conservancy diversion area under control 2.Water conservancy diversion area under control 2 length are than the long 0-1000mm of air inlet diameter in the adsorption gas flow, the mozzle effect in water conservancy diversion area under control 2 is to reduce the impact of air-flow to import department's bed surface, require the mozzle in water conservancy diversion area under control 2 to be not perforate or a small amount of perforate, if a small amount of perforate then requires percent opening between≤30%.
Described mozzle and antipriming pipe 3 are to be made into integration with same pipe, or the multistage pipe is weldingly connected, and whole bottom is provided with passive bracing frame 5 and transition region bracing frame 6, and the former position is in the end or near the end, the latter makes with metal material in the middle of being positioned at relatively.The concordant place that interior air inlet pipe is connected with the external admission pipe is provided with delivery port.Need certain space below the adsorbent bed of the present invention, antipriming pipe diameter peak from the bed surface distance of placing adsorbent greater than 100mm.Also can surround the last layer silk screen outside the described antipriming pipe 3, the screen opening rate is at 10-70%.
The present invention is at absorber single socket compound tense not, and it is inner and be fixed on the bracing frame to put into absorber; Also can send into compound absorber inside to parts assembles.Note making it when being heated, can extend during assembling and move, welding after air inlet aligns with external admission mouth delivery port in making, and stay some slits.During use, when the adsorption gas flow radial air inlet of horizontal absorber, be horizontally through and be parallel to the adsorbent bed of the cylindrical shell longitudinal axis, when the inlet air flow flow velocity is big, allow air-flow be introduced into this device, by the guiding of water conservancy diversion area under control and antipriming pipe, the length direction of the whole bed surface of air flow direction is by the antipriming pipe of certain percent opening, the mean flow rate that the control air communication is crossed antipriming pipe so just reduces airflow kinetic energy ρ v greatly below 3m/s
2Make air-flow evenly be ejected into whole absorption bed surface below, the air-flow that has been changed direction cushions the back and rises below bed surface, keep under the bed surface certain height being arranged, just can make to have changed direction by the air-flow that concentrated on air inlet originally with greater impact power, reduced impulsive force, reduced flow velocity, the whole horizontal bed surface that evenly leads, thus played the effect of uniform adsorption gas flow.
