Bag filter is a versatile filtration equipment with a novel structure, small size, easy and flexible operation, energy saving, high efficiency, closed operation, and strong practicality. It is a new type of filtration system, and the interior of the bag filter is supported by a metal mesh basket filter bag. The liquid flows in from the inlet, passes through the filter bag, and flows out from the outlet. Impurities are intercepted in the filter bag, and can continue to be used after replacing the filter bag

Below, the editor will briefly introduce the structure and working principle of bag filters, as shown below:

Bag filters have many advantages such as reasonable construction, good sealing, strong circulation ability, and easy operation. Especially the probability of side leakage of the filter bag is small, which can ensure the filtration accuracy correctly and quickly replace the filter bag, reducing the operating cost. The inner and outer surfaces of the filter are mechanically sandblasted and polished, which is uniform and easy to clean. We know that the filtering method adopted by bag filters is the side in and side out method, or the side in and bottom out method. The liquid medium to be filtered is pressed or drawn into the bag filter barrel through the pressure in the pipeline. The liquid medium to be filtered is filtered by the filter bag supported by the filter blue through electric polishing punching, and the changed solid and liquid reach the result of filtering the liquid medium separately.

The structural design of the bag filter is to seal the top cover and filter cartridge with four sets of pendulum type ring head bolts and lock them, so that the filter can better withstand high filtration pressure and water hammer pressure impact. The bag filter consists of three parts: filter cartridge, filter basket, and filter bag, with a compact and simple structure; The liquid to be filtered enters through the inlet of the filter and flows into the filter bag. After being intercepted by the filter bag, it flows out through the outlet of the filter. The inlet and outlet design of bag filters generally adopts a side in and bottom out method, which is convenient for cleaning.
