[0002] With the development of society, people have higher and higher requirements for environmental protection. Bag filter, as a dust collector with good filtering effect, has been used more and more. Its dust removal process is: dust-containing gas enters the middle box from the air inlet, enters the bag from the outside of the filter bag, the dust is blocked on the surface outside the filter bag, the purified air enters the bag, and then enters the upper box from the upper part of the bag, and finally discharged from the exhaust pipe. In addition to the correct selection of filter bag materials, the cleaning system plays a decisive role in the performance of bag filter. For this reason, the cleaning method is one of the characteristics that distinguish bag filter, and it is also an important part of the operation of bag filter.
