Dust removal and environmental protection equipment manufacturers introduce the use and maintenance of pulse bag filter

The general problems and precautions of the use and maintenance of the off-line pulse bag filter can be divided into three aspects, such as excessive dust emissions, higher than normal pressure of the filter, and too short filter bag life. There is a clear relationship between the three The introduction is as follows:

Dust emissions exceeded

Basic reasons for excessive dust emissions

1.The initial layer on the surface of the filter bag is not enough;

2.The filter bag is damaged;

3.Poorly assembled filter bag;

In the operation of the dust collector, if the discharge exceeds the standard and the operating pressure of the dust collector is too low than the design, it is most likely that the initial powder layer on the surface of the filter bag is insufficient. The reason may be that the filtration speed of the filter bag is too high, The cleaning cycle is too short, the pressure of blowing compressed air is too high, and the load of dust is reduced.

Studies have shown that: too high filtration speed will increase the dust discharge rate, too high filtration gas velocity will break the initial dust layer, and the dust will impact the filter bag and cause excessive wear. If the filter bag is washed too often at this time It is easy to cause the fabric of the filter bag to loosen, which will cause the dust collector to exceed the standard.

When setting the pulse cleaning cycle of the dust collector, it is necessary to ensure that the dust collector works under a stable pressure, and the set pulse cleaning cycle time is the longest. The pulse cleaning time is to ensure that the initial dust does not fall off. The shortest cleaning is good. If the initial dust layer is insufficient, you can use the extended cleaning cycle to compensate. If you use pressure difference control, you can improve the stability of the inlet and outlet pressure settings of the dust collector.

If the excessive discharge of the dust collector occurs only after cleaning the filter bag, it is only necessary to check whether the pressure of the compressed air for pulse cleaning is too high.

The load reduction of dust may be caused by the reduction of productivity, or the maintenance and adjustment of the control system of the dust collector. The solution: You can use a light load to slowly start the loading or use the pre-dust method.
