Working principle of purification mode of oil fume processing equipment
1. Working principle of high-voltage electrostatic fume purifier:
The kitchen oil fume mixture of the oil fume treatment equipment is collected and enters the oil fume purifier. First, large particles of oil droplets and some impurities are adsorbed and filtered due to inertia and collision with the filter. At the same time, the pretreatment section has the characteristics of automatic oil draining and does not block, and impurities can be trapped in the pretreatment section, thereby ensuring the normal operation of the electric field.
The flue gas concentration after the pretreatment device is relatively balanced, so when passing through a certain high-voltage electric field, it is struck by a large amount of electric charges in the electric field, and a large number of oil particles in the oil and gas are highly ionized, decomposed and carbonized. And a large number of negative ions are generated, and the oil particles suspended in the oil fume are charged. The charged oil particles are driven to the dust collector by the electric field force, reach the electrode plate and lose their charge, and finally deposit on the dust collector plate; the cleaned up-to-standard gas is discharged to the atmosphere.
2. Characteristics of high-voltage electrostatic fume purifier:
电场 The structure of the electric field adopts the structure of pole wire-plate or double plate, which can increase the corona current and greatly improve the purification efficiency. The electric field adsorption electrode plate is made of alloy aluminum plate, which can improve the conductivity of static electricity. The electrode wire is made of stainless steel material, which overcomes the phenomenon that the ordinary purifier is affected by the electrode wire's normal discharge due to the corrosion and break of the electrode wire and causes the electric field to fire and fail to work, thereby ensuring the stable operation of the equipment.
传统 The traditional purifier uses a self-made discrete power supply. The high-voltage output transformer is often damaged, and the equipment cannot run for a long time. The oil fume processing equipment adopts a fully-sealed oil fume purifier dedicated power supply, which can avoid the electrical control humidity caused by the harsh environment caused by rainy and foggy weather, resulting in burnout and damage to the electrical control system components. At the same time, the automatic protection function of the digital display intelligent module is added. During the use of the device, due to the long-term no cleaning, the electrodes are narrowed or the short circuit is caused by the thickening of the pollutants. The electronic control monitoring system will The actual situation is correspondingly protected, and the automatic recovery function is used at the same time, which can avoid permanent shutdown caused by instantaneous overcurrent and overvoltage. It guarantees the stability and safety of operation, and will not cause hidden fire hazards.
(3) The equipment electric field purification unit and pretreatment device adopt a drawer-type design and a modular structure. Disassembly and assembly of various components can be performed anytime, anywhere. It is really fast and easy to install. The equipment body is made of A3 carbon steel material and then electrostatic sprayed. The equipment is not easy to corrode and has a long service life.
