The process of filtering with a bag filter mainly involves the following steps:

1、 Structure and Material

Structure: The bag filter element consists of a filter bag and a filter shell. Filter bags are usually made of materials such as cellulose, polyester fibers, polypropylene, etc., and are used to filter liquid or gas impurities of different particle sizes. The filter shell is generally made of materials such as stainless steel and fiberglass, used to support the filter bag and protect its internal structure.

Type: There are two types of bag filter cartridges: mesh belt type and capillary tube type. The mesh belt filter element is made of mesh belt fabric and other materials, with the characteristic of low pressure drop, but the filtration accuracy is relatively low; Capillary type filter cartridges are made of materials such as fibers and capillaries, which have high filtration efficiency but may be accompanied by high pressure drop.

2、 Filtering principle

Stacked structure: The bag filter adopts a stacked structure, and through the design of a circular flow channel, the hoses are connected to the inlet and outlet respectively. When the liquid or gas to be filtered enters the interior of the filter cartridge, they will pass through the pores of the filter bag.

Intercept impurities: During the filtration process, the fabric or mesh belt of the filter element will intercept and retain impurities, while pure liquid or gas enters the outlet of the filter element through the filter bag, thereby achieving the purpose of purifying and filtering.

3、 Filtering method

Gravity filtration: In some cases, a bag filter can rely on gravity to filter, meaning that the liquid to be filtered naturally flows into the filter under gravity and flows out after filtration.

Pressure filtration: This is the most common filtration method. Apply pressure in the bag filter to force liquid or gas to filter out through the fine holes of the filter bag. This method can improve filtration efficiency and is suitable for situations that require rapid filtration.

Suction filtration: Unlike pressure filtration, suction filtration filters impurities by extracting fluid from the opposite direction. This approach may be more suitable in certain specific application scenarios.

4、 Maintenance and replacement

Regular maintenance: As the filtration process progresses, pollutants on the filter element will gradually accumulate, leading to a decrease in filtration efficiency. Therefore, it is necessary to regularly inspect and clean the filter element to ensure its normal operation and extend its service life.

Replace the filter element: When the filtration efficiency of the filter element decreases to a certain extent, it is necessary to replace it with a new one in a timely manner. This not only ensures the filtration effect, but also avoids excessive clogging of the filter element and damage to the filtration equipment.

5、 Application Fields

Bag filter cartridges are widely used in various industries such as biomedicine, food and chemical industry, electronic 3C, cosmetics, etc. due to their high efficiency and easy maintenance. These industries have high requirements for filtration accuracy and efficiency, and capsule filters can precisely meet these needs.

Above, the capsule filter element achieves efficient purification and filtration of liquids or gases through its unique structure and filtration principle. During use, it is necessary to pay attention to regular maintenance and replacement of the filter element to ensure its normal operation and extend its service life.
