What are the purification technologies of catering oil fume purifier? It is very important to install the cooking fume purifier. Can help us solve the harm of lampblack. See below if you want to know.

first, mechanical methods. The mechanical method of cooking fume purifier is to collect oil fume by inertia and filtration. When the oil mist passes through the grille and the oil mist net cover, the oil mist particles are separated from the airflow by inertia and collision and flow into the oil tank by changing the airflow direction. Filtration means that the oil fume passes through the filter material, collides with the filter material, intercepts, is adsorbed and purified.

second, the high-voltage electrostatic method. The high-voltage electrostatic method of cooking fume purifier is that the voltage of 221v is transformed into tens of thousands of volts through a transformer, and then converted into direct current through a rectifier, so that a strong electric field is formed between the two plates, and the charged oil fume particles are subjected to gravity, electrode attraction and wind field dynamics between the electrodes. Because the charge of particles increases with the increase of particle size, large particles are greatly influenced by electric field force, and their removal rate of aerosol pollutants is relatively high, reaching 81%-91%.

third, wet treatment. The wet treatment method of catering oil fume purifier is to spray oil fume with water mist (adding some chemical reagents to water to increase absorption), so that the surface area of water-oil contact increases and the absorption capacity of water to oil fume increases, thus achieving the purpose of removing oil fume particles. The key to adopting wet treatment method is the absorption performance of absorption liquid for oil smoke, and the design of washing and absorption structure is also very important in wet treatment technology.
