Bag filter is a kind of multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work and strong applicability. Bag filter is a new type of filtration system. Inside the bag filter, the filter bag is supported by a metal mesh basket. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag and can be used continuously after replacing the filter bag.
Working principle of bag filter
Here is the bag filter working principle: The bag filter has many advantages such as reasonable structure, good sealing, strong circulation performance, and easy operation. In particular, the probability of side leakage of the filter bag is small, the filtering accuracy can be correctly guaranteed, and the filter bag can be changed quickly, which reduces the operating cost. The inner and outer surfaces of the filter are solved by mechanical sandblasting and polishing, which is average and easy to clean.
The filtration method adopted by the bag filter is a side-in side-out method, or a side-in-bottom-out method. The filtered liquid medium is pressed into or drawn into the bag filter barrel by the pressure in the pipeline to filter The liquid medium is filtered by the filter bag supported by the filter basket through the electro-polishing punching hole, and the changed solid and liquid reach the result of the liquid medium being filtered.
