The filter element is the most important part of the filtrate filter, which is used to screen or purify pollutants from the filtrate and meet the requirements of liquid filtration. Capsule filter cartridge is a commonly used filter cartridge in filtrate filters, which has the characteristics of large filtration area, low filtration pressure, high filtration efficiency, and can filter out large pollutants. It is widely used in various industrial fields.
The main principle of a bag filter element is to utilize the structure of the filter element. The outer surface of the filter element is made of fabric or mesh, and the inner surface of the filter element is made of capillaries or fibers, forming a multi-layer structure. A bag like space is formed between the inner and outer surfaces of the filter element. When liquid flows into the bag like space from the outer surface of the filter element, pollutants will be intercepted by the fabric and mesh of the filter element, thus achieving the purpose of purifying the filtrate.
There are two types of bag filter cartridges: mesh belt type and capillary tube type. The filter material of capillary tube filter cartridge is made of fiber, capillary tube and other materials, which has high filtration efficiency and can filter out small pollutants, but has a high pressure drop; The mesh belt filter is made of mesh belt fabric and other materials, which has low pressure drop but cannot filter out small pollutants.
During the filtration process, the accumulation of pollutants on the filter element of the bag filter will reduce the filtration efficiency of the filter element, thereby reducing the quality of the purified filtrate. Therefore, it is necessary to regularly check and clean the filter element during use to ensure the cleanliness of the filtrate and ensure the normal service life of the filter element. At the same time, the appearance of the filter element should be regularly checked. If there is any deformation or damage, a new filter element should be replaced in a timely manner to ensure the quality of the filtrate and the normal operation of the filtrate filter. Bag filter cartridges have the characteristics of high filtration efficiency, low pressure drop, large filtration area, and the ability to filter out large pollutants. Therefore, they are widely used in various industrial fields, providing effective protection for purifying filtrate.
