摘要：

针对焦炉烟气的脱硫脱硝环保处理问题，提出了一种集成烟气余热回收、湿式超强湍流氨法脱硫及强制氧化尿素脱硝方法的一体化工艺和装置结构，在实现烟气脱硫和低温脱硝达标排放的同时，可副产低压蒸汽及硫酸铵，装置可消除氨逃逸，无废水废渣排放。

Abstract:

Regarding to the SOx and NOx contained in coke oven flue gas,an integrated wet desulfurization and denitration process and structure combining the processes of flue gas waste heat recovery,wet super turbulent ammonia desulfurization and forced oxidation of urea denitration is proposed.With application of this new technology,the discharged coke oven flue gas can meet the standard requirement after desulfurization and low temperature denitration,low pressure steam and ammonia sulfate are produced as by-products,escaping of ammonia can be avoided and no waste water or slag is discharged.
