Description
Technical field
This utility model relates to a kind of flue gas processing device, especially relates to a kind of flue gas washing cleaner for processing boiler smoke.
Background technology
Boiler fume desulfurizing method uses wet dedusting desulfurization mostly at present.
Traditional wet desulfurizing process, substantially utilizes alkalescence desulfurizing agent first by the SO in flue gas in reaction unit (mixing, washing facility)2Neutralize, make SO2Deviate from from flue gas and enter in recirculated water in a salt form, carry out solid-liquor separation the most again, reach desulfurization purpose, make flue gas be purified.The subject matter that this technique exists: one is that alkaline matter consumes greatly, and the operating cost of processing means is high, and bed drain purge is big, easily blocks pipeline；Two is in actual applications, management difficulty is big, it is difficult to add alkalescence desulfurizing agent in time, when water circulates in a device, acidity is continuously increased, pH value constantly reduces even reduces to 1, desulfuration efficiency constantly declines, and makes acidic circulation water that equipment and water pump pipeline etc. are caused heavy corrosion, causes device damage not use.
Secondly, CN 102151480A discloses a kind of feeding by boiler smoke in conventional wash absorption equipment with neutral water washing absorption SO2, re-absorption SO2Acid water be neutralized, then carry out solid-liquor separation.But the boiler flue gas desulfurization device disclosed in this patent, including washing absorption equipment, is connected with neutralization reactor, Aeration tank, intermediate pool, eddy flow concentrator, circulating water pool in turn after washing absorption equipment；Washing absorption equipment is made up of the venturi shower being sequentially connected with, spiral scrubber, king-tower, secondary tower, wherein the smoke outlet tube of venturi shower connects with spiral scrubber, the smoke outlet tube of spiral scrubber connects with the bottom of king-tower, the flue at king-tower top connects with secondary tower, the drain pipe of spiral scrubber, king-tower and secondary tower is connected with neutralization reactor, and circulating water pool is connected with venturi spray system, spiral scrubber spray system, the water inlet of king-tower spray system by water pipe again.Cleaning dust and the desulfurized effect of the washing absorption equipment of this boiler flue gas desulfurization device are relatively poor, and the desulfurization and dedusting difficulty that result in follow up device increases, and the water consumption of equipment is higher.
CN 104107610 A discloses a kind of water desulfurizing-dusting device, comprising: tower body, the lower end of its inner chamber is provided with hopper, and hopper is provided with water level conditioning chamber, and the upper end of the inner chamber of this tower body is provided with shower；The bottom of this tower body is provided with air inlet；The top of this tower body is provided with gas outlet；Inducing QI dividing plate, is provided with several this inducing QI dividing plates the most obliquely in tower body, these several inducing QI dividing plates are parallel to each other, and the unsettled setting in relatively low one end of this inducing QI dividing plate each；Water storage dividing plate, is provided with this water storage dividing plate in tower body between the inducing QI dividing plate that each two is adjacent, and this water storage dividing plate is parallel to inducing QI dividing plate, and the higher unsettled setting in one end of this water storage dividing plate, and each water storage dividing plate forms a reservoir with the inwall of tower body；And drain tube, this drain tube is provided with a draining valve corresponding to each reservoir.Although this water desulfurizing-dusting device increases the impact between flue gas and moisture film, improve dust removal efficiency, but its treatment quantity is less than normal.
