Cooking fume purifier / structural features: thereby ensuring the normal operation of the electric field. The concentration of smoke after pretreatment is relatively balanced, so in a certain high voltage electric field, it is impacted by a large number of charges from corona discharge in the electric field. A large number of oil particles in the oil smoke gas are highly ionized, decomposed and carbonized, and a large number of negative ions are generated, so that the oil particles suspended in the oil smoke gas are electrified.
The charged oil particles move to the dust collecting pole driven by the electric field force, lose the charge to the polar plate, and finally deposit on the dust collecting board. The purified standard gas is discharged into the atmosphere. 2. The working principle of mechanical filter oil fume purifier: oil fume is imported through the air inlet. Firstly, large particle oil droplets and some impurities are adsorbed and filtered due to the inertia effect and fire net collision, so that the concentration of oil particles after the pretreatment section is greatly reduced, while the pretreatment section has the characteristics of self moving leachate and no blockage, and impurities can be withheld in the pretreatment section. The uniform soot gas flowing through the pretreatment section enters the filtering section. In the over treatment section, special materials with lipophilic properties are used as adsorbent filters. The airflow is compressed and expanded in this part, so that most of the large particle oil in the airstream is suspected to be filtered by the inertia effect and the oil affinity material on the treated material. Finally, the concentration of the lampblack gas discharged from the outlet is greatly reduced, so that the cooking oil fume emission standard is achieved, and the minimum removal efficiency of the soot is greater than 65%.
Product characteristics 1. Ensure stable operation of equipment. 2. The traditional purifier adopts self-made discrete power supply, and the high-voltage output transformer is often damaged, and the equipment can not run for a long time. All the equipment of our company adopts the full sealed type special power supply for fume purifier, which can avoid the bad environment caused by rainy and foggy weather, which leads to electrically controlled wet guide, equipment electric field purification unit and pretreatment device all adopt drawer type design and modular structure. Disassembly and assembly of components can be done at any time and place. The installation is quick and easy to clean. The machine body is made of A3 carbon steel after electrostatic spraying. The equipment is not easy to corrode and has long service life. Electrostatic type - double voltage, high and low pressure interlaced way, the ionization zone adopts imported tungsten steel wire, discharge evenly, high and low pressure area as a whole, 130 million volt high pressure, can adsorb larger oil particles, 6000 volts of low pressure can adsorb smaller oil particles, small to 0.01 microns. Therefore, the adsorption efficiency is higher than other products.
Plate material: the autocratic corrosion resistant aluminum plate is not corroded during the use and cleaning process, thus ensuring the purification efficiency of the product, and the service life can reach more than 5 years. The spacing between the suction plates: the distance between the plates in the low pressure area is no more than 8mm, and the adsorption area is 30% larger than that of the ordinary products, so that the adsorption capacity of the electric field is greatly improved.
