Electrostatic oil fume purifier is the mainstream equipment of oil fume purifier in China at present. The working principle and advantages of its purification are very attractive. Let's explain it to you from Jinan oil fume purifier manufacturer.
Purification process principle of electrostatic fume purifier
Flue gas separation:
Under the action of external high voltage, electrons released from or near the surface of the metal wire of the negative electrode quickly move to the positive electrode, collide with gas molecules and ionize. When the oil fume exhaust gas passes through this high-voltage electric field, the oil fume particles will be charged due to the gas ions captured by the collision in a very short time, and move toward the positive electrode dust collecting plate under the action of the electric field force, so as to achieve the separation effect.
This kind of equipment has the advantages of less investment, small land occupation, no secondary pollution and low operation cost. Because it is easy to capture dust with small particle size, the purification efficiency is high, up to 85~95%. Its purification advantage is that the separation force is electrostatic force, which directly acts on particles rather than on air flow. Therefore, it has the characteristics of low energy consumption and low resistance.
Electrostatic particle charge:
When the gas containing dust particles passes through the high-voltage electric field formed between the cathode line (also known as corona electrode) connected with the high-voltage DC power supply and the grounded anode plate, the corona discharge occurs at the cathode and the gas is ionized. At this time, the negatively charged gas ions move toward the anode plate under the action of the electric field force, and collide with the dust particles during the movement, so that the dust particles are negatively charged. The charged dust particles are charged by the electric field force, It also moves towards the anode. After reaching the anode, the electrons carried are released, and the dust particles are deposited on the anode plate, and the purified gas is discharged out of the duster.
Technical advantages of electrostatic oil fume purifier:
1. The treatment air volume is large and the pressure loss is small. It can operate under high humidity.
2. The removal rate of one pass can meet the purification requirements.
3. The diameter range of particles effectively removed is large.
