国内现有各种形式的电渣炉近百台,少数采用湿法去氟,易造成二次污染,多数采用直接排空的方法以减少车间氟的浓度。但仍超标(达2.6毫克/标米~3),且污染面扩大。齐钢引进的西德电渣炉烟尘收集和气体净化系统,采用干法净化,其排空尾气含氟浓度小于1毫克/标米~3,可满足电渣车间环境保护的需要,而且治理彻底,不产生二次污染。 Nearly one hundred domestic electroslag furnaces of various forms are available in the country. A few of them use wet de-fluorination to easily cause secondary pollution. Most of them use the method of direct emptying to reduce the concentration of fluorine in the workshop. However, it still exceeded the standard (up to 2.6 mg / m 3) and the pollution area expanded. The introduction of the West Germany slag furnace slag collection and gas purification system, the use of dry purification, the exhaust fluorine concentration of less than 1 mg / m3, to meet the needs of the environmental protection of the electroslag workshop, and thorough governance , Does not produce secondary pollution.
