Description
Technical field
The utility model relates to field of Environment Protection, especially relates to a kind of application SCR technology equipment for denitrifying flue gas.
Background technology
Sulfur dioxide and nitrogen oxide affect larger gaseous contaminant in atmosphere pollution, has high risks to human body, environment and the ecosystem, along with the increasingly stringent of environmental requirement, and NO
xand SO
2the problem of discharge more and more receives publicity.Sulfur dioxide and nitrogen oxide mainly stem from the combustion process of the fossil fuel such as coal, oil, and the roasting of ore, the fume emission of smelting process, wherein various burning boiler particularly power plant boiler smoke evacuation there is the features such as concentration is low, exhaust gas volumn is large, floating dust is many and be difficult to administer.In conventional art, desulfurization and denitration are normally separately carried out by discharge sulfur dioxide in flue gas and purification of nitrogen oxides technology, which results in the defects such as the complexity of discharging flue gas purification system is huge, initial outlay is large, operating cost is high, seriously constrain the actual enforcement of discharge flue gas desulfurization and denitrification.Flue gas desulfurization technique is mainly based on Gypsum Wet, rotating spraying semidry method, in-furnace calcium spraying afterbody humidification activation, sea water desulfuration, electron-beam desulfurization, flue gas circulating fluidized bed desulfurization etc., wherein Wet Limestone method is the tail flue gas desulfur technology be most widely used in the world now, its subject matter is that the solubility of absorbent (lime or lime stone) is little, utilization rate is low, and waste residue amount is large; Gas denitrifying technology mainly contains SCR technology (SCR), SNCR technology (SNCR), electronic beam method, impulse electric corona method, complex compound absorption process and urea absorptive method etc., gas denitrifying technology mainly SCR technology, SNCR technology and SNCR/SCR combination technique comparatively ripe in current operation, but there is initial investment costly in SCR method, operating temperature range is narrow, and there is NH_3 leakage, can N be generated
2o, and the shortcoming such as catalyst easy in inactivation.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of compact conformation, enclosed application SCR technology equipment for denitrifying flue gas, and the technical scheme of employing is as follows:
A kind of application SCR technology equipment for denitrifying flue gas, comprise air inlet pipe, air inlet pipe comprises preheating device, air inlet pipe connects WITH AMMONIA TREATMENT tank, WITH AMMONIA TREATMENT tank connects atomization process tank, atomization process tank connects cyclone dust collector, cyclone dust collector connects SCR reactor, WITH AMMONIA TREATMENT tank top is provided with ammonia spray device, WITH AMMONIA TREATMENT tank bottom is provided with ammoniacal liquor recovery tube, atomization process tank top is provided with multilayer atomized water shower, atomized water shower bottom is provided with filter grid, Sewage treatment pipe is provided with bottom atomization process tank, cyclone dust collector top is provided with rinse water water inlet pipe, the bottom of cyclone dust collector is provided with residual cake valve.
Further, described preheating device is electric calorifie installation.
Further, described atomized water shower is 3-5 layer.
Further, described SCR reactor adopts replaceable nido reactor.
Further, described filter grid adopts resin material to make.
Adopt above-mentioned equipment for denitrifying flue gas, compact conformation, exhaust treatment efficiency is high, and does not have ammonia to reveal, and avoids secondary pollution.
