How does the polishing and dust removal company ensure that the initial dust does not fall off?
The reduction of the dust load of the polishing and dust removal company may come from the reduction of the output rate, or the inspection and adjustment of the control system of the bag filter. Way to solve. Studies have shown that: too high filtration speed will increase the dust discharge rate, too high filtration gas speed will break the initial dust layer, and the dust will impact the filter bag and cause excessive wear. High can easily lead to loose fabric in the filter bag, 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 unreasonable 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 time 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 chaos 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.
In the operation of the dust collector, if the discharge exceeds the standard and the dust collector's operating pressure is too low than the design, it is most likely that the initial powder layer on the surface of the dust filter bag is insufficient. The reason may be that the filter bag ’s filtration speed is too high, The cleaning cycle of the bag is too short, the pressure of blowing compressed air is too high, and the load of dust is reduced.
The industrial filter dust collector has a larger volume and a longer filter cartridge. How to ensure that the upper, middle, and lower parts of the entire filter cartridge can achieve a good dust removal effect; industrial dust removal is generally carried out on-line. Ash, how to minimize the interaction between the filter cartridges without affecting the dust removal effect, these issues need further study in the future.
