提钒尾气的治理

THE TREATMENT OF EXTRACTING VANADIUM TAIL GAS

分析了钒渣提钒和石煤提钒尾气中有害气体产生的原因,综合论述了当前该类尾气处理的几种方法,并且比较了各自的优缺点,对提钒尾气的治理提出了展望。

This paper analyzes the causes of harmful gas produced in extracting vanadium from vanadium slag or stone coal.It discusses several methods of treating tail gas such as by alkali liquor of NaOH,by water then NaOH solution,by lime milk,by water and FeCl 2 and compares their advantages and disadvantages.It puts forward the prospect of the treatment of extracting vanadium tail gas.
