氨法脱硫工艺（Ammonia desulfurization process） The ammonia desulfurization process is based on the basic mechanism of reaction between ammonia and SO2 and water. The main processes are wet ammonia method, electron beam ammonia method, pulse corona ammonia method, simple ammonia method, etc.. 1, electron beam ammonia (EBA) and pulse corona ammonia (PPCP) Electron beam ammonia method and pulse corona ammonia method are respectively by electron beam irradiation and pulsed corona injecting water and ammonia, is cooled to 70 DEG C of the flue gas, under strong electric field, flue gas ionization, a high-energy electron, electron activation, pyrolysis, ionization of other flue gas molecules, to produce a variety of active particles OH, O, HO2 and other free radicals. In the reactor, SO2 in flue gas, NO active particles and free radical oxidation for high order oxides of SO3, NO2, HNO3 and the formation of H2SO4 and H2O in the flue gas after meeting with NH3 or other neutral injection case generation (NH4) 2SO4/NH4NO3 aerosol, again by dust collection. The electric field of the flue gas desulfurization and denitrification reactor with pulse corona discharge has the function of dust removal. The energy consumption and efficiency of these two ammonia methods still need to be improved. The main equipments, such as high-power electron beam accelerator and pulse corona generator, are still in the stage of development. 2 simple ammonia method Simple method of ammonia commercialized TS PS ammonia desulfurization process, mainly by gas simple rapid response design of H2O, NH3 and SO2 under the condition of the device, strictly speaking is not a simple method of ammonia recovery of ammonia, the desulfurization product is mostly aerosol state instability the sub salt recovery is very difficult, not economic law reflects ammonia desulfurization products with flue gas; and after emptying and there will be part of the decomposition of SO2, the formation of two pollution. Therefore, the proces
