It obtains cap-type filter plate 101 to teetertotter, overhanging spring 102 can guarantee that cap-type filter plate 101 shakes in a certain range, to avoid covering
101 transition of type filter plate, which is shaken, causes the excessive bleed of absorbing liquid, the industrial tail gas after absorbing liquid absorbs formed clean gas from
The gas vent 44 at 4 top of washing tank is discharged.
The course of work：Industrial tail gas is passed through inside dirt pocket 1 by No.1 air inlet 12, opens rotary electric machine, rotation
Motor driven turntable 74 rotates, and turntable 74 drives knockout head 72 to swing back and forth by connecting rod 73, so that the solid-state in industrial tail gas
S-type curve when sand is fallen is conducive to the intensive for improving the distribution of solid-state sand, to be conducive to improve dust removing effects.
When solid-state sand falls down to form sand waterfall industrial tail gas across sand waterfall, solid-state is transferred heat to
Sand, solid-state sand are fallen down under the effect of gravity, since sand has the function of heat absorption heat preservation, can be absorbed in industrial tail gas
Heat simultaneously is used to heat the water in water tank 751, to realize making full use of for the waste heat in industrial tail gas；Open water pump, water
Water in water tank 751 is pumped into annular diversion pipe 753 and is transported to inside dirt pocket 1 by pump, since there are viscous resistances for solid-state sand
Power, water can be rinsed solid-state sand, prevent solid-state sand to be difficult to flow out from dirt pocket 1, solid-state sand is directly over sand screen
Center and protective case 83 are fallen down to transmission belt 2, and water can be flowed into filter from filter sand hole 821 under the action of adherent effect
In reservoir chamber 812 between sand plate 82 and out 81 inner wall of sandpipe, water is flowed out from the water outlet 811 of 81 side wall of sandpipe out again, with reality
The recycling of existing water；Water inside reservoir chamber 812 is transported to 752 top of deflector by water pump, and passes through annular diversion pipe 753
It is transported to 1 inner wall of dirt pocket, water flows through deflector 752 along the inner wall of dirt pocket 1, and flow to out sandpipe 81 by deflector 752, and one
Aspect is conducive to the flowing of solid-state sand, helps solid-state sand to be discharged from dirt pocket 1, on the other hand advantageously reduces solid-state sand to water conservancy diversion
The abrasion of plate 752, to improve the service life of deflector 752.
After solid-state sand is fallen in transmission belt 2, solid-state sand is transported to inside dust removing pool 3 by conveyer belt, opens stirring motor
91, stirring motor 91 drives agitating shaft that dust is removed in the solid-state sand washing entered in dust removing pool 3, is then turned on screw conveyor 92, spiral shell
Rotation conveyer 92 transports the solid-state sand after washing away dust to sand storage chamber by conveyance conduit, realizes sufficiently following for solid-state sand
Ring utilizes.
After industrial tail gas passes through sand waterfall, port 13 and connecting pipe 42 are crossed from washing by 1 the right side wall of dirt pocket
No. two air inlets 41 of 4 bottom sidewall of tank enter inside washing tank 4, industrial tail gas by next chamber by taper filter opening 1011 into
Enter to a upper chamber, taper filter opening 1011 is conducive to being sufficiently mixed for industrial tail gas and absorbing liquid, to be conducive to organic matter
Removal；Open circulating pump 103, under the action of circulating pump 103, absorbing liquid by circulating line 104 reach washing tank 4 in by every
In multiple chambers that absciss layer is partitioned into, absorbing liquid carries out industrial tail gas to be sufficiently mixed absorption, while when industrial tail gas passes through
When taper filter opening 1011, cap-type filter plate 101 can be made to teetertotter, overhanging spring 102 can guarantee cap-type filter plate 101 in certain model
Interior shaking is enclosed, so that 101 transition of cap-type filter plate be avoided to shake the excessive bleed for causing absorbing liquid, the industry after absorbing liquid absorbs
Tail gas forms clean gas and is discharged from the gas vent 44 at 4 top of washing tank.
Clean gas passes through connecting tube 5 from gas outlet discharge, and 51 pairs of drying layer in connecting tube 5 absorb clean after washing
Residual liquid is absorbed in gas, and the clean gas after drying enters back into activated carbon adsorption case 6, activated carbon adsorption
Case 6 absorbs harmful organic substance remaining in clean gas, so by multistage exhaust treatment system, can achieve pair
The multistep treatment of VOCS tail gas guarantees the cleaning of the gas of discharge.
Industrial applicibility
According to the present invention, which can carry out multistep treatment to industrial tail gas, and then realizes the abundant of resource and follow
Ring utilizes, so that this processing system is useful in gas processing device field.
