Bag filter (function: filter impurities, etc.) The important part is called the filter bag (filter material: PE, PP, PTFE, PMIA, NMO). The quality of the filter bag determines the user's filtering effect to a large extent, and the dust on the filter bag How to deal with it? Before that, let's take a look at the types of bag filter bags. The actual form of alloy catalysis is not necessarily an alloy under the reaction conditions. Alloy catalysts are generally composed of active metals and inert metals, which can show the geometric or group effect of one metal being diluted by another metal, as well as the "ligand" effect of electronic interaction. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and more and more come into the daily life of ordinary people. After the water to be treated by the filter passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, only the detachable filter cartridge needs to be taken out and reinstalled after treatment. Therefore, the use and maintenance are extremely convenient.

Types of filter bags:

1. According to the filtering method of the filter bag, it is divided into: external filtering and internal filtering.

2. According to the use environment and temperature program of the filter bag, it is divided into: normal temperature, medium temperature and high temperature.

3. According to the shape of the cross section of the filter bag, it is divided into flat bag (trapezoid and flat) and round bag (cylindrical).

4. According to the way of air inlet and outlet, it is divided into: lower air inlet and upper air outlet and upper air inlet and lower air outlet and direct current type (only limited to plate-shaped flat bag).

Filter bag dust treatment method:

1. Manual tapping: each filter bag is tapped manually to remove the dust on the filter bag of the bag filter.

2. Mechanical rapping for dust removal: divided into top rapping and middle rapping for dust removal (both for filter bags). The mechanical rapping device periodically beats each row of filter bags in turn to remove the filter. Dust on the bag.

3. Gas dust removal: Gas dust removal uses high-pressure gas or external atmosphere to blow back the filter bag to remove the dust on the filter bag. Gas cleaning includes pulse jet cleaning, reverse blowing and reverse suction.
