半密闭式电石炉烟气治理设备选择与实践

Selection and application of equipment for controlling flue dust of semi closed carbide furnace

电石生产中排放的烟尘严重污染了环境，烟气治理的关键是对电石炉进行改造。介绍了电石炉主要设备的改造过程。改造后，平均排放含尘质量浓度为４０．３ｍｇ／ｍ３，除尘效率达９９％。

Revamption of carbide furnace, the key measure to eliminate flue dust,is introduced.As a result of the refitment of its main installations, 40 3 mg/m 3 of average mass concentration of dust emission, with dust removing efficiency 99%, is reached.
