一.前言铸造工厂散发出来的大量粉尘,严重污染着周围环境,必须尽快解决,刻不容缓。冲天炉炉气净化是其中的一个重要方面。一九七八年根据上级下达的任务,我们两单位合作完成了5吨/时冲天炉消烟除尘装置的设计,并于去年3月投入运转。整套装置为“多管水冷旋风除尘器——五层颗粒层除尘器”系统。多管水冷旋风除尘器用作第一级除尘并起冷却作用,由于结构形式 I. Preface The large amount of dust emanating from foundry factories seriously pollutes the surrounding environment and must be solved as soon as possible without delay. Cupola furnace gas purification is one of the important aspects. In 1978, according to the tasks assigned by the higher authorities, the two units jointly completed the design of a smoke and dust removal device for a 5 ton / hour cupola and were put into operation in March last year. The whole set of equipment is “multi-tube water-cooled cyclone - five layers of particle dust collector” system. Multi-tube water-cooled cyclone dust for the first stage and play a cooling role, due to the structure
