1. 破碎工序
外购加入中频熔炼炉的硅铁等原料需要进行破碎,选用1台单台破碎能力为1吨/小时的鄂式破碎机,破碎机工作时间为520h/年。破碎机破碎过程有粉尘产生,含尘废气粉尘产生浓度约3000mg/m3左右,经密闭罩收集后,进入布袋除尘器除尘净化,除尘效率99%,除尘后粉尘排放浓度为30mg/m3,满足《大气污染物综合排放标准》(GB16297-1996)中表2二级标准,实现达标后经20m高排气筒排放。

  鄂式破碎机破碎产生的粉尘使用1套布袋除尘器处理,废气量为1000m3/h,处理前粉尘产生量为1.56t/a,处理后粉尘排放量为0.0156t/a。

  根据《工业源产排污系数手册(2010修订)》,铸铁件感应炉熔铁废气产生量为400m3/吨·产品,烟尘产生量为0.5kg/吨·产品。本项目一期年处理铁水量4.44万吨,二期年处理铁水量13.07万吨,设备年运行时间为4800h。经计算,一、二期废气产生量共约14592m3/h、烟尘产生量为18.24kg/h,烟尘产生浓度为1250mg/m3。中频感应电炉拟安装整体可移动密闭罩(捕集率95%),产生的熔炼废气经密闭罩收集后,含尘气体先进入旋风除尘器降温、除尘,然后进入布袋除尘器处理(中频炉烟气布袋除尘器需使用高温除尘布袋),除尘效率>98%,除尘后烟尘排放浓度为25mg/m3,排放量为1.76t/a,满足《工业炉窑大气污染物排放标准》(GB9078.1996)中表2二级标准,然后经20m高的排气筒排放。
