How to filter glass fiber coated cloth bags in use
The film covering process is based on the ordinary filter material as the base cloth, and is covered with a film with special properties to make filtering more precise. It is more efficient for dust removal and the longer the service life of the bag. The more obvious advantages of the membrane covered filter bag are as follows: generally, industrial cloth bags are deep filtration, and effective filtration is achieved by forming a dust layer on the surface of the filter bag It takes a long time to form effective filtration, which is about 10% of the whole filtration process. The resistance is relatively large and the efficiency is very low. The interception is incomplete. The pressure during filtering and back blowing is also relatively high. The dust removal is frequent, the energy consumption is high, the service life is not long, the equipment covers a large area, and the coated dedusting bag filter material is used. The dust cannot penetrate into the filter material. It is surface filtration. Both coarse and fine dust are deposited on the surface of the filter material, That is to say, the filtrate is trapped by the pore diameter of the membrane itself. Without the initial filtration period, effective filtration starts at the beginning, and nearly 100% of the time is in filtration.
The products are widely used in steel, cement, chemical industry, power plant, road building, metallurgy, grain processing, etc.
