LXB type natural wind pulse backflush bag dust collector

Working principle of natural wind pulse backflush bag dust collector The dust-containing gas enters the middle box and is filtered and purified by the filter bag. The dust is blocked on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag mouth. Exhaust air outlet.
As the dust on the surface of the filter bag continues to increase, the pressure difference between the inlet and outlet of the dust collector also rises. The pulse controller sends instructions regularly and the dust cleaning system starts to work. The natural wind pulse bag dust collector is a kind of dust removal equipment with large air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, easy maintenance and small floor space. The special flue gas inlet settlement design allows large particles to settle first, reducing the load on the bag. Because this equipment adopts advanced technology in dust cleaning technology, dust collector main structure, and automatic control, it has good effects on the treatment of sticky fine dust, high temperature and high humidity flue gas, and high concentration flue gas.
In the working state, the flue gas penetrates from the outside of the bag to the inside of the bag, and the dust is blocked by the filter cloth on the outer surface. As the dust accumulates, the flue gas resistance will increase. Generally, the flue gas resistance is controlled at Dust state, the shape of the bag changes from the working state to the cleaning state in an instant (approximately), and then from the cleaning state to the working state. This process causes the bag to vibrate strongly, causing the dust accumulated on the surface of the bag to quickly shake off, and then Returned to working condition. Bag cleaning is the main determinant of bag dust collector resistance, dust removal effect and bag life. Cleaning with too much compressed air will not only damage the bag, but also shorten the service life of the bag (some bags can only have a life of half a year and due to the destruction of the bag The dust layer on the surface thus reduces the dust removal effect, because the dust removal effect of the bag dust collector does not depend on the filter material, but depends on the formation of an effective dust layer on the surface of the filter material. The real dust removal effect is formed on the surface of the filter material. Dust layer, destroying the dust layer also destroys the dust removal effect of the filter material. Therefore, compressed air dust cleaning will affect the dust removal effect of the bag.
