The dust removal mechanism of the pulse dust collector is not clear as the filtration mechanism, but the SIIC team can introduce the following points:
(1) Comprehensive actions theories: In the process of studying the dust cleaning mechanism of the pulse bag filter, some researchers think that several dust cleaning mechanisms of the mechanical vibration bag filter are also suitable for the dust cleaning mechanism of the pulse bag filter. The reason is that the principle of mechanical dust removal is that the filter bag shakes to produce elastic force to make the dust and dust mass attached to the filter bag leave the filter bag and fall down. The size of the shaking force is related to the driving device and frame structure. The shaking force is related to the driving device and frame structure. The driving device has large power and small energy loss of frame transmission, so the mechanical ash removal effect is good. The situation of pulse dust remover is also the comprehensive effect of various mechanisms, but the pulse dust remover has great energy and good dust removal effect.
According to the comparison of the cleaning methods for the bag filter with a filtering area of 1000m2, the power consumption of the bag filter is as follows:
(2) the theories of air reversed blowing. Some researchers think that the air flow through the filter bag reversely plays an important role in the soot cleaning. On the one hand, the reverse air flow directly impacts the dust block; on the other hand, due to the change of air flow direction, the filter bag produces expansion and contraction deformation, which makes the dust block fall off. The size of the counter blowing air directly affects the cleaning effect.
The theories of reverse air flow can clearly explain the problem of dust removal of the pulse jet plastic burning plate dust remover and the pulse jet ceramic tube dust remover, as well as that of the ordinary pulse bag dust remover.
