Classification And Use Of Filter Bags

Filter bags mainly include two types, liquid filter bags and air filter bags. As filter equipment, filter bags are also an important part of the filtering process. The quality of filter bags determines the effect of filter bags to a large extent. It can be targeted to meet the application of many fields.

Generally, the bag mouth ring of the liquid filter bag can be stainless steel ring, galvanized ring, polypropylene plastic ring, and the liquid filter bag has different bag bottom and bag top designs. There are many advantages of liquid filter bags. For example, liquid filter bags are generally produced by high - speed industrial sewing machines without silicone oil, which will not cause problems such as silicone oil pollution. There is no high protrusion at the seam of the liquid filter bag to cause side leakage, and there is no needle hole to cause side leakage. The labeling of the product specification and model of the liquid filter bag is easy to remove, so as to prevent the contamination of the filtrate by the label ink during the use of the filter bag. The filtration accuracy of liquid filter bags is very small, and the materials are generally polyester, which will be collectively referred to as polypropylene filter bags. The liquid filter bag adopts the argon arc welding technology of stainless steel and galvanized steel ring, and the diameter error is small. The purpose of choosing this steel ring is that the filter bag can be installed in the equipment to improve the degree of sealing, thereby reducing the incidence of side leakage. Liquid filter bags are mainly used to filter various chemical liquids such as inks, coatings, food, etc. The liquid filter bags have the characteristics of acid resistance and high mechanical strength of alkali fibers, which can be used repeatedly.

Air filter bags include Air Conditioner Filter Media filter bags and dust removal bags. The filter bag of the air system is mainly used to filter the air dust particles in the air supply system. The effect after filtering is generally to meet the environmental requirements of dust - free production, while the dust bag is mainly used for the treatment of industrial exhaust gas in the exhaust system. . The dust bag has the characteristics of high strength, wear resistance, acid and alkali corrosion resistance, folding resistance, easy cleaning, water and oil repellency. The dust bag is mainly used in steel, cement, chemical road construction, power plants, metallurgy, grain processing, etc.
When we use Filter Cloth Material, we should check in advance whether the specifications and models of the installed filter bags are consistent with the interface of the filter bags, and check whether the new filter bags are insufficient. The use of the Air Filter Cloth filter bag must be used together with the support net, and it must be close to the inner wall of the support net. We should pay attention to check whether the inner wall of the support net has burrs. When the pressure difference between the upstream and downstream of the filter is at a certain value, we should consider replacing the filter bag with a new one, or cleaning the filter bag.
