Bag filter the filter cloth is woven from fibers just like cloth, so the bag filter cloth has high flexibility and ductility. It is precisely because of this that the filter cloth will be affected during the use of the bag filter. It is easy to cause damage, especially when hard objects appear on the filtered material. When the filter cloth is punctured, the filter cloth will be worn during operation, so that the filter will not have a great effect.

The mesh number is an important parameter of the filter cloth, and the size of the parameter indicates the number of filter holes of the filter cloth. The smaller the mesh number, the larger the filter holes of the bag filter, on the contrary, the smaller the filter holes of the bag filter cloth. Therefore, in the process of filtering the material, the filter cloth with a small mesh will cause a lot of solids to pass through the filter cloth in a normal way, resulting in the liquid after the filtration is not clear and bottomed.

When the bag filter is filtering high-viscosity liquids, compressed air can be introduced through the exhaust valve to accelerate the discharge of residual liquid and shorten the waiting time. Please note: The air used for pressurized discharge must be stable, and the pressure should not exceed the working pressure of the filter. The operation steps are as follows:

1. Close the input valve.

2. Open the intake valve.

3. The gas is introduced into the bag filter, and the remaining liquid is drained under pressure.

4. Check the outlet pressure gauge to confirm that the gauge pressure is equal to the compressed air pressure; confirm that no liquid flows out of the outlet.

5. Close the intake valve.

6. Open the exhaust valve slowly; the outlet of the exhaust valve has residual liquid sprayed out, and it must be led to a safe place or the suction port of the filter.

7. After the compressed air is exhausted, close the exhaust valve. At this time, there should be no pressure inside the filter and the cover can be opened.
