Description

The sack cleaner of the desulfurization of water spray, denitrogenation
Technical field
The utility model relates to a kind of environmental protection equipment, particularly a kind of bag-type dust collecting equipment with the desulfurization of water spray, denitrification functions.
Background technology
China is maximum in the world coal production and country of consumption, and is annual to airborne release SO 2There are 2 400 ten thousand tons, NO 2There are 7,000,000 tons, and volume of smoke. a large amount of SO 2And NO 2The sour deposit fouling that pollutes and cause thus, caused serious harm to health, agricultural, forest, fishery, material etc.
China's boiler smoke abatement dirt device all belongs to dry type, wet type eddy dust-removing device and electrostatic precipitator, its efficiency of dust collection does not reach standard for boiler soot discharge, atmospheric environment is polluted, especially the clearance of the sulfur dioxide in boiler smoke, nitrogen oxide is not high, to the pollution of atmospheric environment, very large to the health hazard of human body.For this reason, country has dropped into huge manpower, financial resources, still can not effectively be administered; The reasons such as the consumption huge fund has been introduced many covers large power plant flue gas treatment technology from external, but all huge because of its plant investment, and operating cost is high, and floor space is large, can not promote the use.Especially, for the medium small boiler user, owing to there is no economical and practical flue gas treating process and device, and be forced to adopt the probable thermo oil boiler of the expensive right gas of right material.
Do not reach environmental emission standard in order to solve existing boiler smoke abatement efficiency of dust collection, remove sulfur dioxide and nitrogen oxide in boiler smoke, reduce most important to the pollution of atmospheric environment.
The processing method of flue gas is very many, and the method relevant to this technique has wet method-ammonia desulfurizing process and dry method-limestone-gypsum method.
In the wet method ammonia-process desulfurization technique, the more representational ammonia fertilizer method desulfur technology that East China University of Science's exploitation is arranged, it adopts ammonia is desulfurizing agent, circulation absorbs S02 in absorption tower, again through processes such as oxidation, crystallization, dryings, but producing ammonium sulfate byproduct. and technical process is numerous and diverse, and equipment is huge, plant investment is expensive, and operating cost is high.
In spray-drying-desulfurization by dry method, all adopt at present the method that absorbs SO2 by-product CaSO4 (gypsum) in flue gas take milk of lime as desulfurizing agent in spray drying tower, exist too technical process numerous and diverse, the situation that equipment is huge, and, its by-produced gypsum price is low, can't effectively utilize, and major part is abandoned and caused secondary pollution.
In addition, about flue gas ash removal, the water law efficiency of dust collection is low, consumes great lot of water resources and forms secondary pollution, and this is smoke pollution to be converted to water pollute.The commercial power that electric precipitation consumption is a large amount of, move cost higher, and the inefficiency of electric precipitation, easily form discharge beyond standards when the handle high voltages high concentrations of gas.Dry method high pressure or Low-Pressure Pulse Bag Filter have good dust removing effects, but its ability that removes simultaneously the multiple pollutants such as sulphur in flue gas, nitrogen, mercury is very weak.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of bag-type dust collecting equipment that is integrated with the desulfurization of water spray, denitrification functions is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The sack cleaner of the desulfurization of a kind of water spray, denitrogenation, comprise casing, air inlet, gas outlet, clean room, filter chamber, ash bucket, filter bag, deashing mechanism, and blower fan, in described casing, be provided with spray desulfurizing tower before gas outlet.
Further, described spray desulfurizing tower comprises spray chamber, shower, dividing plate, discharge outlet, and its outlet pipe is connected with gas outlet, and then with blower fan, is connected.
As preferably, described casing consists of shell and liner, its shell welded steel plate, and its liner forms with anti-corrosion material.
As can be seen from the above technical solutions, useful technique effect of the present utility model is: the utility model desulfurization, denitrogenation, efficiency of dust collection are high, and flue gas resistance is little, compact conformation.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Wherein: 1-casing, 2-air inlet, 3-gas outlet, 4-ash bucket, 5-blower fan, 6-filter bag, 7-clean room, 8-filter chamber, 9-deashing mechanism, 10-spray chamber, 11-shower, 12-dividing plate, 13-discharge outlet.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is done further specific description.
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of sack cleaner that is integrated with the desulfurization of water spray, denitrification functions.Concrete technical scheme is as follows:
The sack cleaner of the desulfurization of a kind of water spray, denitrogenation, comprise casing, air inlet, gas outlet, intake valve, air outlet valve, clean room, filter chamber, ash bucket, filter bag, deashing mechanism, compressed air piping, and be provided with spray desulfurizing tower.
Before described spray desulfurizing tower was positioned at casing, gas outlet, it comprised spray chamber, shower, dividing plate and discharge outlet, and its outlet pipe is connected with gas outlet, and was connected to blower fan.
Described casing consists of shell and liner, its shell welded steel plate, and its liner forms with anti-corrosion material.
Operation principle of the present utility model is: dusty gas is passed into casing 1 by air inlet 2; Open negative-pressure air fan 7, the interior space of casing 1 is under negative pressure state; Open intake valve 12; Dusty gas passes into filter bag 6 under the attraction of negative-pressure air fan 7; The dust-removing gas body that filters through filter bag 6 enters the spray desulfurizing tower spray chamber; The dust-removing gas body is through desulfurization removing nitric after shower spray, and the clean gas after desulfurization removing nitric is by gas outlet, so by negative-pressure air fan 7 discharged in atmosphere.
The embodiment of above sack cleaner to a kind of water spray provided by the utility model desulfurization, denitrogenation is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, such as position of box shape and spray desulfurizing tower etc., all can do respective change according to actual needs.In sum, this description should not be construed as restriction of the present utility model.
