Cause analysis of dust leakage in self cleaning air filter
If the self-cleaning air filter in the normal operation process, there is dust leakage, mainly and equipment seal, filter wind speed and dust bag related, dust leakage will not only affect the normal operation of the equipment, but also lead to unqualified emissions, the following is the cause analysis of the self-cleaning air filter dust leakage.
1. Filter the wind speed
The filter material of self-cleaning air filter is generally divided into two kinds: normal temperature and high temperature. The normal temperature wind speed is controlled within 1.0-2.0, and the high temperature wind speed should be controlled between 0.8-1. If the wind speed is too high, the dust adhesion force on the surface of the filter bag is too strong.
2. the selection of dust bag
Dust bag as an important component of self-cleaning air filter, plays an irreplaceable role in the filtration process, if the weight of dust bag is insufficient or the density is too small will form dust leakage, resulting in self-cleaning air filter unqualified.
3. Equipment sealing
Self-cleaning air filter is assembled by the upper body and bucket of the clean air chamber, among which the door and the upper box meeting bucket joint is connected by screws, such as sealing strip or unqualified sealing strip when connecting operation, dust leakage will be formed.
Its working principle is to use the high pressure electric field to ionize the flue gas, and the dust charge in the air flow is separated from the air flow under the action of the electric field. The dust collector has high efficiency, low resistance, convenient maintenance and management. It has the same effect as industrial dust precipitator in collecting fine dust particles.
Self-cleaning air filter is suitable for collecting fine, dry, non-fiber dust, using the filter effect of fiber fabric to filter the dust containing gas. When the dust containing gas enters the equipment, the dust with large particles and significant ratio settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified.
Above is the reason for the dust leakage of the self-cleaning air filter analyzed by Xiaobian. I hope you can have a further understanding of the self-cleaning air filter after reading it. If you have this need, please feel free to contact us for consultation.
