Cement kiln desulfurization system and desulfurization method |
| abstract |
The invention relates to a desulfurization system and a desulfurization method, in particular to a cement kiln desulfurization system and a desulfurization method for a cement kiln; ammonia water is sprayed into a preheater, and ammonia water reacts with SO generated in the preheater to form ( NH 4 ) 2 SO 4 ; the generated ammonium sulfate enters the bag filter after passing through the waste heat power generation boiler with the flue gas; the dust of the bag filter is collected into the ash bin, and the desulfurized flue gas enters the chimney; The ash containing (NH 4 ) 2 SO 4 is conveyed to the middle and upper part of the calciner; the ammonium sulfate generated in the desulfurization process is generated in the calciner to form stable sulfate, which enters the rotary kiln and finally exits the rotary kiln with clinker. This method has low investment, high efficiency, no secondary pollution, and can effectively solve the problem of excessive emission of SO 2 content in chimney flue gas of cement plant ≤ 1000mg/Nm 3 . |
