Description
Technical field
The utility model belongs to field of fume treatment equipment, relates to a kind of flue gas ammonia method desulfurizing denitrification apparatus.
Background technology
SOx, NOx are the main sources of atmosphere pollution, cause huge harm to environment.
At present, flue gas desulfurization technique comparative maturity, wherein wet processing occuping market share is maximum, still the selective catalytic reduction (SCR) of flue-gas denitration process overwhelming majority employing at present, the method utilizes ammonia under the effect of catalyst, NOx to be reduced to N2 as reducing agent, process system and equipment more complicated.Existing device systems is all that desulphurization denitration is separated process, cause whole desulfurizing and denitrifying process complexity, equipment investment costly, the utility model is in conjunction with existing fume treatment auxiliary, develop a kind of reliable, flue gas desulfurization that cost of investment is lower, denitration device, tally with the national condition, there is good application prospect.
