二硫化钼生产工艺废气处理新方法

摘要

介绍了一种新型的废酸气处理方法。在真空的作用下，废酸气先通过碱罐被碱液吸收，然后通过净化罐被尿素还原吸收。该法处理含氮氧化物废酸气吸收效果较好，所需设备简单。在正常生产工艺运行时，废气净化效率可达到93％以上。%A new method about waste gas treatment was introduced.Making use of vacuum air,the waste acid gas was firstly absorbed by lye in lye tank,and then was absorbed in cleaning tank by urea.It was an effective treat-ment for waste acid gas containing nitrogen oxides with simple production equipment.In the normal production process running,the waste gas purification efficiency could reach up to 93%.
