Referring to Fig. 1, the impact type wet scrubber comprises upper box 2 and lower box 1, hold in the lower box 1 and purify waste water, upper box 2 is arranged on the top of lower box 1, its inside is provided with impact tube 6, impact tube 6 one ends are communicated with air inlet 12 on being arranged on upper box 2, and the other end connects shower nozzle 5 and is arranged on purifying waste water below the liquid level in the lower box 1, is provided with the air outlet 10 that connects negative pressure at upper box 2 tops; In lower box 1, be provided with overflow pipe 13, overflow pipe 13 1 ends are arranged in the lower box 1 concordant with the liquid level of purifying waste water, the other end stretches out from lower box 1 bottom and is communicated with back pool 18, the bottom of back pool 18 is provided with sewage immersible pump 17, sewage immersible pump 17 connects the water inlet pipe 15 of lower box 1, in conjunction with referring to Fig. 2 and Fig. 3, lower box 1 one sides are provided with a ball float groove 27 and lower box internal communication, being provided with lower box liquid level float switch 4 in ball float groove 27 is electrically connected with water pump, back pool 18 is provided with filling pipe 20 and replenishes or change purifying waste water in the back pool 18, and filling pipe 20 is provided with back pool ball-cock assembly 19 control filling pipes and opens or close.Be provided with for the stop valve of changing in the lower box 16 of purifying waste water in the bottom of lower box 1, lower box 1 outer surface is provided with liquid level gauge 14 and shows the liquid level position of purifying waste water in the lower box.
Referring to Fig. 4 and Fig. 5, the header 7 that is provided with seven row's sealings in the upper box 2 is communicated with air inlet 12, the bottom connection of each header 7 is provided with five impact tubes 6, be provided with parallel one on header 7 tops and ranked first water fender 8, be provided with one on first water fender, 8 tops and ranked second water fender 9, the two rows water fender is crisscross arranged and realizes removing airborne moisture.Be provided with dust block board 11 removes air inlets and sucks big dust particle in the gases in the inner positions near air inlets 12 of upper box 2.
In the present embodiment, upper box 2 is installed on the lower box 1; Back pool 18 places by lower box 1 side.Fill with in the lower box 1 and purify purifying waste water of dusty gas, its liquid level is concordant with the overflow pipe 13 upper end mouths of pipe; Overflow pipe 13 outlets are positioned at back pool 18 tops, and the water that overflows from overflow pipe 13 can directly enter back pool 18; The water inlet pipe 15 of lower box 1 links to each other with the sewage immersible pump 17 that is arranged on the back pool bottom; Lower box liquid level float switch 4 places in the ball float groove 27 of lower box 1, controls the unlatching of back pool sewage immersible pump 17 according to the height of 1 li purification of lower box water liquid level.The dust removal process of whole deduster carries out under negative pressure state, the deduster inner chamber is in negative pressure state when unit start starting, liquid level in the lower box 1 will rise and surpass the overflow pipe 13 upper end mouths of pipe, and the part water that surpass this moment will overflow to back pool by overflow pipe 13; In running, the dusty gas impact liquid level has clashed into a large amount of foams and water droplet, and part foam and water droplet will overflow to back pool by overflow pipe 13; And along with the part evaporation of water, purifying waste water in the deduster will reduce gradually, when the liquid level of purifying waste water in the deduster is lower than specified altitude, transmit the signals of telecommunication by lower box liquid level float switch 4 this moment and purifying waste water of 18 li of back pools is pumped into by water inlet pipe 15 after-purification water is after reaching specified altitude in the deduster for sewage immersible pump 17, sewage immersible pump 17 stops pumping.The liquid level of deduster lower box is subjected to the accurate control of overflow pipe 13 and lower box float switch 4, liquid level in the back pool 18 then replenishes by back pool ball-cock assembly 19 control filling pipes 20, so just effectively guaranteed the stationarity of whole unit operation, and the recycling water that purifies usefulness in the deduster is not fallen it by spill losses.
Ash-laden gas through the exhaust column extraction, after being entered by air inlet 12, bigger dust granules is stopped backward being removed down by dust block board 11, less dust granules is along with air-flow together enters header 7, at this moment dusty gas is through impact tube 6, from shower nozzle 5 ejections, impact liquid level has clashed into a large amount of foams and water droplet, reaches the purpose that purifies air with this with higher speed.Cleaned air passes (Fig. 1 with dashed lines arrow is represented) is discharged by air outlet 10 by first water fender 8 and second water fender 9 under the effect of blower fan, and the water droplet that wherein contains is removed by first water fender 8 and second water fender 9.
In addition, dust is deposited in the accumulation of deduster bottom land becomes waste residue, and existing wet scrubber does not possess the automatic slag removal function, enters deduster inside by operating personnel and carries out scarfing cinder, the big potential safety hazard of useless power and existence when useless.Referring to Fig. 2, in lower box 1, be provided with slag notch 21 and chain rubbing board mechanism 3, slag notch 21 is arranged on the position that is higher than the liquid level of purifying waste water in the lower box 1 by an inclined-plane, chain rubbing board mechanism 3 comprises a drive rod assembly 23 and at least one driven shaft assembly 26 that is set in parallel in lower box 1 inside, wherein drive rod assembly 23 is connected with decelerator electric machine assembly 22, two chains 25 that are provided with rubbing board 24 install around respectively on the sprocket wheel of drive rod assembly 23 and driven shaft assembly 26 two ends correspondences, and rubbing board 24 contacts with the inclined-plane with the bottom surface of lower box 1.
After dusty gas was cleaned, its clean gas was discharged by air outlet 10, and its dust granules is retained down by water and is deposited in lower box 1 bottom, can regularly open chain rubbing board mechanism 3 according to the dusty gas dust concentration, removes the waste residue of lower box 1 bottom.
The water that whole unit Purge gas is used needs to change fully behind the operation certain hour, only needs this moment manual unlocking to be positioned at the stop valve 16 of deduster bottom, and the sewage that contains a large amount of dust is discharged through discharge outlet.After sewage has been arranged, close stop valve 16, this moment, fresh water flow to back pool 18 by ball-cock assembly 19, and reached specified altitude up to liquid level in sewage immersible pump 17 suction deduster lower boxes 1.
