The specific embodiment
Below in conjunction with accompanying drawing and specific implementation method, describe the present invention in detail, in exemplary embodiment and description of the present invention, be used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 2, air cleaning facility of the present invention comprises collecting plate 1, voltage generator 2, conductive material component 3 and air driven device 4.
The quantity of described collecting plate 1 comprises more than one, and it is for collecting koniology particle.The quantity of collecting plate is determined according to practical application.Different application need to be used no volume, between collecting plate, by stack, can increase dust-collecting area.Due to current process limitation, the average thickness of collecting plate is about 1mm.The pattern making that collecting plate of the present invention also can adopt plastic uptake to produce goes out thinner collecting plate, the about 0.2mm of thickness.One side surface of collecting plate 1 or both side surface are provided with disturbs the air-flow of its side of flowing through to produce the thrust array 11 of local turbulence.Thrust array 11 has certain shape and puts in order.The pattern that collecting plate of the present invention can adopt plastic uptake to produce or plastic sheet be carried out to roll extrusion, thrust array can be implanted upright fibre columns by other techniques and form.
Described conductive material component 3 has one or more groups, and it is located at collecting plate 1 surface, between conductive material layer 3 and collecting plate 1, is provided with air gap 5, between conductive material layer 3 and collecting plate 1, does not contact.Wherein, every group of conductive material component 3 comprises two conductive material layers, at least comprises a collecting plate between two conductive material layers.When collecting plate is superimposed by stacking form, organizes conductive material component more and be located in stacking collecting plate array.The polarity of the close conductive material layer of two adjacent groups conductive material component is contrary.In whole collecting plate array, form the opposite polarity structure setting of adjacent conductive material layer.Be that voltage generator applies high pressure and low pressure to all electrically conductive materials layer alternately.
Described voltage generator 2 is for providing high pressure and low pressure.Voltage generator 2 applies high potential and electronegative potential to two conductive material layers of every group of conductive material component respectively, the electrically charged particle thing of the air-flow of its thrust array 11 so that the collecting plate absorption between two conductive material layers is flowed through.During particle in utilizing electrostatic precipitation principle absorbed air, the particle that silicate geometric ratio resistance is higher is difficult to polarized or charged, thereby is not easy to be hunted down.As shown in Figure 3, the thrust array being interspersed is set on collecting plate in the present invention, the air-flow of the thrust array of flowing through is disturbed and produces local turbulence.In local turbulence, thereby the higher particle sharp impacts of silicate geometric ratio resistance is trapped in the percent of pass that reduces this type of particle on the boundary-layer of side concave surface of thrust under the pressure reduction of fluid and turbulent flow.
Described air driven device 4 is for driving air to pass through from collecting plate surface.Because the present invention need to upset air-flow by thrust array, form local turbulence, need to drive air-flow to reach certain wind speed by air driven device and just can satisfy condition.Air driven device 4 can be blowing type, can be also air draught type.Air draught type is applicable to the not too wide situation of collecting plate width.
