Development History Of Bag Type Dust Collector

Jul. 23, 2019

Bag Type Dust Collector removal is an older dust removal technology. It was applied as early as the 1880s. At that time, only some hanging bags were used, and the work efficiency was low. In 1881, the mechanical vibration dust bag filter of the Betch plant in Germany began commercial production. In 1954, HJHersey invented the reverse spray type blowing ring cleaning technology, which enabled the bag filter to achieve continuous operation of dust removal and cleaning, the treatment volume was increased several times, and the pressure of the filter bag was stable. In particular, the pulse-jet (pulse) bag filter invented by TVReinauer in 1957 is considered to be a major discovery of bag-type dust removal technology. It not only operates and cleans continuously, but also reduces the pressure loss of the filter bag. Increased, and there are no moving parts inside, the filter cloth has a longer life and a simple structure. After the 1970s, the bag filter technology was developed to a large scale. In the United States, Japan, Australia and Europe, combined with large-scale industrial production, large bag filters have been developed for use in coal-fired power stations, dry cement kiln kiln tails and electric furnace dust removal. A single filtration area of more than 10,000 m2 is not rare.
