14th, the 3rd valve 15, pretreatment unit 16, after-treatment device 17, water treatment facilities 18；One group of deflection plate 4 is located at the He of air inlet 2
Between gas outlet 3, and it is staggered up and down；Shower 9 is located between top adjacent baffle 4；The one end of return duct 6 and body 1
Bottom is connected, and the other end is connected with water inlet pipe 5；The one end of outlet pipe 7 is connected with return duct 6, the other end and water receiver 12 connect；Overflow
Head piece 11 is located at the bottom of body 1, and the one end of overflow pipe 8 is connected with water receiver 12；First valve 13 is on water inlet pipe 5, the second valve
Door 14 is on return duct 6, and the 3rd valve 15 is on outlet pipe 7；The quantity of deflection plate 4 is 7.
The top downward of pretreatment unit 16 set, including solid collecting layer 19 and be sequentially connected sand stone layer 20, match somebody with somebody
Air chamber 21, multistorey strainer mesh layer 22, solid collecting layer 19 are connected by porous plate 23 with gas distributing chamber 21 and multistorey strainer mesh layer 22, multilayer
Filter mesh layer 22 includes the filter screen that one group of aperture is sequentially reduced and is obliquely installed, and gas outlet and the air inlet 2 of multistorey strainer mesh layer 22 connect
Connect；
After-treatment device 17 includes desiccant layer 24, active carbon layer 25, the Electrostatic Absorption layer 26 being sequentially connected from bottom to top
With filter screen 27, Electrostatic Absorption layer 26 is interior to be provided with one group of Electrostatic Absorption piece 28；

The new sulphur ammonium tail gas clean-up deduster operation principle is as follows：
Recirculated water is flowed back by water inlet pipe 5, shower 9, body 1, return duct 6；Pass through the overflow of overflow pipe 11, the overflow mouth of pipe
It is recirculated water to arrive the bottom of body 1 below；Handled, avoided using water after a period of time using water treatment facilities 16 in water cycle process
Capacity reduces, and treatment effect reduces.
Come to the preprocessed device processing of dust-containing tail gas of coke-oven plant's ammonium sulfate workshop section fluid bed dryer, first pass around sandstone
17 coarse filtration of layer, then the multistorey strainer mesh 19 that via hole diameter is sequentially reduced filter, and the coarse granule filtered down is solid because gravity drops to naturally
Body collecting layer 20, the treating capacity of body 1 is substantially reduced after pretreatment, improves treatment effeciency；Gas is entered by air inlet 2 again
Enter in new sulphur ammonium tail gas clean-up body of deduster 1, have one group of deflection plate 3 in body 1, dusty gas is around deflection plate about 3
It flow to outlet and remove moist chambers, flowed into by gas outlet 3 in after-treatment device 16, is further adsorbed in active carbon layer again after drying
Dusty gas in tail gas, then remaining powered little particle is adsorbed in Electrostatic Absorption layer 19, pure air row is obtained after filtering
Go out.
When high speed bypasses the gap with the water surface below deflection plate 3 downwards, gas moves in a circle gas, including：(1) wash
Wash dust removal process：Move around the gas of upper baffle, with the water droplet move toward one another sprayed in shower, washed upwards
Dedusting, sulphur ammonium particle is dissolved in water droplet in gas；(2) dust removal process is impacted：In gas sulphur ammonium particle and entrainment water droplet by from
The effect high-speed impact water surface of mental and physical efforts, in the water of bottom, water droplet also converges sulphur ammonium grain dissolution with lower section water.Dust-containing tail gas except
Entering repeat impact dedusting and multiple spraying and dedusting in dirt device, gas is purified, and reach deduster afterbody removes moist chambers,
Here gas flow rate is reduced, and droplet settling is discharged in air to the water surface, last gas from gas outlet 3 in gas.
