Oil fume purifier Fabric filtration method

Oil fume exhaust 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, 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 low investment, low operating costs, no secondary pollution, and convenient maintenance; however, it 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 method for oil fume purifiers: 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, which limits the application of filtration purification equipment.
 
Wet scrubbing method for oil fume purifiers
 
Using water or other detergents, an aqueous film is formed by spraying with a nozzle to absorb oil fume. Oil fume particles come into contact with the water mist and film sprayed from the nozzle, and through the effects of mutual inertial collision, retention, diffusion of fine particles, and mutual condensation, they flow down with the water droplets, thereby separating the oil fume ions from the airflow. This equipment has a simple structure, low investment, small footprint, low operating costs, and convenient maintenance.
 
Disadvantages of wet scrubbing method for oil fume purifiers: There is large resistance, low purification rate for submicron particles, and secondary pollution from oily wastewater.
