等离子熔炼过程中，排放物中含有毒酸性气体和细颗粒粉尘，必须治理。从等离子炉内排出的熔炼尾气进入二燃室、空气稀释降温系统、一级陶瓷过滤器和二级陶瓷过滤器，有害颗粒物和有毒气体经燃烧、沉降、降温、过滤和吸附等过程，不仅使尾气有害成分得到治理，达到欧洲排放标准，而且能收集有价烟尘返回等离子熔炼系统，变废为宝。
In the process of plasma melting, the emissions containing toxic acid gases and fine particles of dust must be governance. The smelting exhaust from the plasma furnace entering the second combustion chamber, air dilution cooling system, primary ceramic filters and secondary ceramic filters, harmful particles and toxic gas after combustion, settlement, cooling, filtering and adsorption process, not only the harmful components obtained governance, and meet European emissions standards, but also can collect the valuable dust return plasma melting system, turning waste into treasure.
