Development of bag filter dust collector in China

According to related manufacturers, in the 1950s, the original Soviet-type products were mainly used. In the 1960s, there were a few design research units in China that modeled the pulse type of the United States, Japan, and other countries. Based on the bag type dust collector, the production of its own products began. 

Phase 2. After 1973, a number of bag filter manufacturers began to appear in China. In the 1980s, some design institutes, research institutes and universities were studying. , introduction, digestion, transplantation. At this time they introduced a large-scale anti-drying bag filter from Japan, combined with the needs of various industries in the country to develop, develop and produce a large anti-blowing bag filter, and developed a sub-room anti-blowing bag filter and long bag and low pulse bag filter, air volume per hour, from 1,000,000 to 2,910,000 M3, the bag length of 10m. in the 1980s, a large reverse air bag filter is preferred steel industry, a large-capacity flue gas purification device. Some problems were gradually exposed in the subsequent use, mainly because the back-flushing method was a flexible cleaning method. Although the damage to the filter bag was small, when the dust was more viscous and the concentration was higher, the resistance rose faster. It is easy to paste bags under certain external conditions.

Phase 3. Since the 1990s, with the successful development of the large-scale pulse bag filter, the development has reached a new level. Large-scale pulsed dust bag filter is relatively large-scale anti-blowing. The biggest advantage of the ash precipitator is that the ash cleaning effect is better, the operation is more reliable, and the service life of the filter bag can be extended.
