Industrial Oil Fume Purifier
Industrial Oil Fume Purifier
Working Principle:
Under high voltage, the negatively charged metal tips (or their vicinity) emit electrons, which rapidly move toward the positive electrode, colliding with and ionizing gas molecules. When oil fume and exhaust gases pass through this high-voltage electric field, the oil mist particles become charged in an extremely short time due to ion capture via collisions. Driven by the electric field force, these charged particles migrate toward the positively charged dust collection plates, achieving separation.
The key difference between this purification mechanism and conventional gas treatment methods lies in the separation force: electrostatic force acts directly on the particles rather than the airflow, resulting in low energy consumption and minimal resistance.
Dust Purification Mechanism:
When gas containing dust particles passes through the high-voltage electric field formed between the negatively charged corona wire (connected to a high-voltage DC power supply) and the grounded positive plate, corona discharge occurs at the cathode, ionizing the gas. The negatively charged gas ions move toward the anode under the electric field force. During this movement, they collide with dust particles, transferring their negative charge. The charged dust particles are then driven toward the anode, where they release electrons and accumulate on the plate. The purified gas is discharged from the dust collector.
Applications:
