Polishing and dust removal company analyzes dust emission standardization
The polishing and dust removal company analyzes the excessively high filtration speed, the dust discharge rate will increase, and the excessively high filtration gas velocity will cause the initial dust layer to break, and the dust will impact the filter bag and cause excessive wear. In this case, the number of cleaning dust filter bags Too high can easily cause the fabric of the filter bag to become loose, 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.
