Description
Technical field
The utility model relates to a kind of environmental protection equipment, particularly a kind of bag-type dust collecting equipment that utilizes dry desulfurization, denitrogenation.
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 bag-type dust collecting equipment of a kind of dry desulfurization, denitrogenation, comprise sack cleaner, spray drying tower, and blower fan, and the gas outlet of described sack cleaner is communicated with spray drying tower.
Further, described sack cleaner comprises casing, air inlet, gas outlet, clean room, filter chamber, ash bucket, filter bag, deashing mechanism.
Further, described spray drying tower comprises flue gas inlet tube, hothouse, smoke outlet tube and rotary nozzle and byproduct outlet.
Further, the smoke outlet tube of described spray drying tower is communicated with the blower fan sealing.
As can be seen from the above technical solutions, useful technique effect of the present utility model is: the utility model in dedusting, can be realized desulfurization, denitrification functions, and efficiency of dust collection is high, flue gas resistance is little, compact conformation, technological process is simple, with wet desulphurization, that corrosivity is compared in denitrogenation is very little, except spray drying tower be in fog the reaction, accessory substance namely is dried to powder in tower, also corrosion-free to tower body, and there is no secondary pollution.
