1. inertial separation method: mainly metal mesh cover, grille and other equipment in the kitchen range hood widely used. The treatment effect is about 40-50%.
2. electrostatic deposition: the main equipments are double zone electrodeposition and double zone dedusting. The treatment effect is more than 80%.
3., liquid washing method: the equipment used for industrial types of wet dust collector, such as sieve tower, impact type of water film dust collector. The treatment effect is about 30-40%.
4. honeycomb deposition method: simple structure, the use of physical cooling principle, so that the rapid condensation of oil and gas, soot and water vapor can be cooled in the chamber, condensed into large particles of oil beads, and produce liquefied oil collection phenomenon. The treatment efficiency is about 60-80%, the resistance is large, the cleaning workload is large, and the consumption of filtration water is large.
The soot pollution of the catering industry can not be underestimated. It not only seriously damaged the urban environment, but also greatly reduced the quality of life of the citizens. Nature based is based on the balance of the ecosystem and is balanced by the balance of the natural system. The intrinsic value of nature is more than a human tool.
