With the enhancement of environmental awareness and the increasing strictness of the national environmental protection policy, the cloth bag dust collector has been widely used in industrial production as an efficient dust removal equipment. As one of the most critical components in the dust collector, the quality of the bag filter will directly affect the dust removal effect and service life of the bag filter. Therefore, the following points need to be noted when choosing a cloth filter bag:

1. Select different types of filter bags according to the characteristics of the processed materials

Different production processes may require different types of filter bags, such as different materials, different apertures, etc. Therefore, the selection of filter bags needs to be selected according to the characteristics of the material treated. For example, for the treatment of high temperature gases and toxic gases in high temperature environments, it is necessary to select a filter bag that is resistant to high temperature and corrosion to ensure the long-term stable operation of the device.

Second, choose the right filter material

The filter material of the filter bag is usually chemical fiber, cotton cloth, glass fiber and high temperature resistant ceramic filter material. Different types of filter media have different wear resistance and corrosion resistance, and the appropriate filter media should be selected according to the characteristics of the treated material and temperature, humidity and other parameters. If the oily fume gas needs to use oil-resistant filter material, the chemical gas needs to choose corrosion resistant filter material.

Third, the structure and size of the filter bag

The structure and size of the filter bag will also affect its use effect. The filter bag of the cloth dust collector usually has a variety of structures such as filter core type, filter bag type and honeycomb type. Different filter bag structures have different advantages and disadvantages, and should be selected according to the actual production needs. For example, for production lines with small dust particle size and large processing capacity, a filter bag model with large filter bag area and compact structure can be selected to meet the needs of production.

Four, filter bag surface treatment

Due to the strong adhesion of some dusts, this brings great challenges to the dust cleaning and service life of the filter bag. Therefore, the surface treatment process of the filter bag is also very important. At present, the surface treatment process of the filter bag includes: film coating treatment, flame retardant treatment, anti-static treatment, etc., which can effectively improve the service life of the filter bag and the cleaning effect.

Five, the manufacturer selection

The manufacturing process, production process and testing means of filter bag have an important impact on its use effect. Therefore, when selecting filter bags, it is necessary to choose a manufacturer with certain production experience, technical strength and professional ability to ensure the quality and effect of the product.

In summary, the quality of the bag filter bag is not only related to the efficiency and service life of environmental protection equipment, but also has a very important contribution to the environmental protection indicators and a good production environment in the production process. Therefore, in the purchase process, it is necessary to consider the material, type, process and other factors of the filter bag from many aspects to choose the most appropriate product to improve the overall benefit of environmental protection equipment.
