1. Mechanical fume purification equipment
Mechanical oil fume purification equipment collects oil fume by filtration, cyclone centrifugation, activated carbon adsorption and other methods. The treatment effect of this treatment method is related to its design, control parameters and materials used. The filtering method adopted by mechanical oil fume purification equipment is to separate oil fume particles from the airflow by changing the airflow direction when the oil fume passes through the grille and the oil mist net cover, and flow into the oil tank by inertia and collision. The filter materials of mechanical oil fume purification equipment are mostly lipophilic polymer materials, which have low cost and the removal rate of aerosol is 40%~? 70%, and the odor purification effect is obvious. The general mechanical fume purification equipment has good adsorption effect at the initial stage of installation. With the attachment of oil fume, the adsorption capacity will gradually weaken, and the filter material must be replaced frequently, which leads to high operating cost. 2. Electrostatic flue gas purification equipment
The electrostatic oil fume purification equipment converts the voltage of 220kv into 1000V through a transformer, and then converts it into DC through a rectifier, so that a strong electric field is formed between two plates, and the particles in the flue gas are charged, and the charged oil fume particles are subjected to gravity, electrode attraction and wind field dynamics between electrodes. Because the charge of particles increases with the increase of particle size, the removal rate of aerosol pollutants by large particles is relatively high, up to 80%? 0 ~90%, the purification efficiency of Yongchuang environmental protection electrostatic fume purification equipment can reach above 98%. The cost of electrostatic oil fume purification equipment is relatively high, but in terms of operation and maintenance, it is simpler than mechanical electrostatic equipment, so in terms of equipment price, the input cost of electrostatic oil fume purification equipment is higher than that of mechanical oil fume purification equipment. On the whole? Electrostatic fume purification equipment is superior to mechanical fume purification equipment. ? 3. Wet flue gas purification equipment
The working principle of wet oil fume purification equipment 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 wet treatment of wet oil fume purification equipment lies in the absorption performance of absorption liquid to oil fume. This method has high purification efficiency, can reduce the temperature of oil fume, and can also remove pungent smells such as pepper and pepper at the same time by adding appropriate chemical reagents. 4. Composite flue gas purification equipment
The working/lighting principle of the compound oil fume purification equipment is: under the negative pressure of the exhaust fan, the smoke first enters the front physical oil fume separator built in the range hood, and under the centrifugal force (1400 rpm) of the physical oil fume separator, the oil fume is physically separated, and 90% of the water vapor and oil fume particles are separated. After separation, the oil fume homogenizing device carries out secondary physical collision interception on the oil fume, intercepts some larger oil fume molecules and intercepts the smoke. Finally, the residual oil fume enters the electrostatic high-efficiency oil fume purification unit for three-stage purification to completely purify the residual oil fume, and finally the clean air is exhausted under the traction of the exhaust fan.
