Working Principle and Disadvantages of Fabric Filtration in Oil Fume Purification Schemes

Working Principle of Fabric Filtration in Oil Fume Purification Schemes: Oil fume waste gas first passes through a certain number of metal grids, where large particulate pollutants are intercepted; then, after passing through filter media such as fiber pads, the particulate matter is removed due to diffusion and interception. The filter material usually selected is a high-polymer composite material with high oil absorption capacity. This equipment has advantages such as low investment, low operating costs, no secondary pollution, and convenient maintenance; however, it also has disadvantages such as large resistance, large footprint, and the need for frequent filter replacement. The purification efficiency is generally 80~92%.

Disadvantages of Fabric Filtration in Oil Fume Purification Schemes: Due to the large resistance of the filter material, such as the pressure drop of a glass fiber filter purifier can reach 1500Pa, and the filter material needs to be replaced frequently, limiting the application of filtration purification equipment.
