    The working principle and application of the settling chamber of the dust collector of shot blasting machine

    The settling chamber of the duster of the shot blasting machine is one of the earliest dust collecting facilities, which is the oldest and simplest dust collecting device. Its working principle is that when the dust gas into a large settling chamber, because the settling chamber's cross-sectional area is much larger than the suction pipe, so the shot-blasting machine dust gas flow rate is greatly reduced, the flow rate can be reduced by 10 ~ 20 times. During the period of dust gas passing through the settling chamber, the larger dust particles in the settling chamber have enough time to settle under the action of gravity, and the purified dust gas is discharged from the other end of the settling chamber. Since the settling chamber is a kind of dust collecting device that USES gravity to make dust settle naturally, it is also called gravity settling chamber or settling chamber for short. The settling chamber of the duster of shot blasting machine has the advantages of simple structure, low cost, small energy consumption, small pressure loss, simple maintenance and management, and can directly deal with high concentration dust-containing gas. However, its huge size and low dust collection efficiency are its fatal shortcomings. In the past, the settling chamber was mainly used in industry to collect dust particles of >40um, or to pre-collect dust in the multi-stage dust collection system. It is not impossible to use the settling chamber for collecting fine dust, but it covers a surprisingly large area. The dust collector system of the shot blasting machine generally takes the settling chamber as the pre-dedusting device of the bag filter, and filters the coarse dust particles in advance to reduce the burden of the bag filter and reduce the wear of dust on the bag.
