冲天炉在熔炼过程中散发大量的粉尘,严重污染大气和环境。就上海市的情况来说,1981年上海机电系统铸铁件年产量约100万吨,其中95％是冲天炉熔炼的,而且2～3吨/时冲天炉占绝大多数,又几乎集中在市区内,对市区的环境污染影响极大。因此,解决好2～3吨/时冲天炉的除尘,具有一定的现实意义。我厂在1980年根据市环保局的要求,通过调研设计了两套冲天炉除尘装置,第一套安装在2吨/时冲天炉上,第二套1982年9月安装在3吨/时冲天炉上,并分别在1981年1月及1982
Cupola emits a lot of dust in the melting process, seriously polluting the atmosphere and the environment. In Shanghai’s case, in 1981 Shanghai Mechanical & Electrical System annual output of about 1 million tons of cast iron, of which 95% is a cupola melting, and 2 to 3 tons / time Cupola accounted for the vast majority, and almost concentrated in the city The district has a great impact on the environmental pollution in the urban area. Therefore, to solve the 2 ~ 3 tons / hour cupola dust removal, has some practical significance. I plant in 1980 according to the requirements of the Municipal Environmental Protection Bureau, through the research designed two sets of cupola dedusting device, the first set installed in 2 tons / hour cupola, the second set in September 1982 installed at 3 tons / The furnace, and respectively in January 1981 and 1982
