Compared with prior art, the utility model has the beneficial effects that
When the utility model is used, dust-laden, tail gas containing NOx that combustion process generates are initially entered and are sunk in expansion chamber
Drop, then multiple groups baffle area is entered by flue, ammonium hydroxide is sprayed from spray head, and flue gas mixes in flue with ammonia, into multiple groups
After baffle area, flue gas and ammonia uniformly mix in this area, and the mixture of flue gas and ammonia enters out of stock catalyst layer, cigarette
NOx in gas can be reacted under conditions of low temperature under the effect of the catalyst with ammonia, and NOx is reduced to nitrogen.It is logical
Setting baffle is crossed, so that ammonia mixes more uniformly with flue gas, to reduce the consumption of ammonium hydroxide, the same of save the cost can be reached
When, improve out of stock efficiency；By the way that expansion chamber is arranged, avoids the dust of bulky grain from entering out of stock catalyst layer, avoid out of stock
Catalyst layer blocking, extends the repair time.
