Oil smoke purifier Activated carbon adsorption method
 

Using granular activated carbon or activated carbon fiber felt to adsorb pollutant particles in oil smoke. This equipment has similar characteristics to filtration purification equipment, but it is more effective in removing oil smoke odor molecules.
 

Main disadvantages of activated carbon adsorption method for oil smoke purifiers: high cost of activated carbon.
 
Fabric filtration method for oil smoke purifier
 

Oil smoke 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-molecular composite material with high oil absorption performance. This equipment has low investment, low operating costs, no secondary pollution, and convenient maintenance management; 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 smoke 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.
