Product Overview
The High Voltage Electrostatic Oil Mist Eliminator is designed for efficient removal of oil mist, oil fumes and fine particles from industrial exhaust gases. By generating a strong electrostatic field inside the unit, tiny oil droplets and particulate matter in the gas stream are charged, driven to the collecting electrodes and removed, achieving both gas purification and oil recovery.
Typical applications include:
Oil mist removal from air compressor discharge
Vacuum pump exhaust purification
Lubrication / hydraulic system vent gas treatment
Metalworking oil mist and oil smoke control
Plastic & rubber processing, textile, printing exhaust gas treatment
Other industrial exhaust streams containing oil mist or fine oily aerosols

Working principle
The corona wire in operation is surrounded by a pale blue electron halo (R= 4-7mm). These high-speed electrons constantly collide with the surrounding gas molecules, dust and tar particles. After being impacted, the gas molecules lose several electrons on the periphery and become positive charge clusters themselves. Under the action of the electric field force, these positron charge groups move rapidly towards the corona wire. During the movement, if they collide with dust and coke particles, the dust and coke particles will be adsorbed onto the corona wire to form cathode scale, while the dust and coke particles that have been collided by electrons become negative charge groups and accelerate towards the precipitation electrode under the action of the electric field force.
After being charged, the dust and coke particles undergo variable acceleration in a non-uniformly distributed electric field. As long as the time it takes for them to reach the sedimentation electrode is less than the residence time of the exhaust gas in the sedimentation tube, the purpose of oil removal can be achieved. The directional movement time is not only related to the mass and charge of the moving particles, but also shortens as the secondary peak voltage increases.
The charged dust and coke adhere to the inner wall of the sedimentation tube by the inertia of movement. The maximum accumulation thickness of the dust and coke depends on the ratio of dust to tar. Due to the high tar content in the exhaust gas, the dust and coke accumulated on the tube wall have a certain fluidity. When the dust and coke reach a certain thickness, they will flow into the bottom of the cylinder along the tube wall by their own weight.
Continuous and intermittent flushing methods are adopted. A continuous flushing tray is set at the upper end of the sedimentation electrode, where the water film continuously descends to carry away the dust adhering to the electrode. An intermittent flushing device is provided on the top cover of the electrostatic filter, enabling the corona electrode to be cleaned regularly.

Performance characteristics
Upgradability: The equipment is equipped with a built-in cleaning function, which can regularly clean the main body of components such as the primary filter screen, cooler, honeycomb electrostatic precipitator, and plate wire electrostatic precipitator. Moreover, the internal device adopts a modular combination that can be disassembled, which not only facilitates the daily automatic cleaning and maintenance of the equipment but also is conducive to the maintenance and replacement of components in the future, making it upgradable.
Anti-electric shock and automation: The safety system is meticulously designed. Once the inspection door is opened, the high-voltage power supply is automatically cut off, eliminating the risk of electric shock caused by human factors. The electrostatic power supply control system can automatically adjust the electric field intensity, ensuring that the purification equipment maintains a high purification rate even after long-term operation. The water tank built into the equipment can automatically separate oil and water from the collected wastewater.
High efficiency and safety: The power control technology features effective start-up, constant current output, automatic cremation control, power short circuit, power overload, power fault prompt and protection functions. The equipment efficiently captures oil particles of different sizes and has a high purification efficiency. It has fundamentally solved the problem of pollution transfer. The equipment is equipped with a closed-loop fire protection system to prevent the situation where the equipment cannot be put out due to water cut-off. It can also be used for steam fire extinguishing and cleaning, which is safer and more efficient than traditional purifiers in terms of fire protection.

Material and maintenance instructions
Material and maintenance instructions
Material: Made of thickened stainless steel 201
Instructions for Use: A. Cut off the main power supply to the main unit, hang a "No Power Supply" sign for repair, and remove the grounding rod of the transformer for grounding treatment. B. Disassemble the maintenance doors of each insulator room. Use a clean cotton cloth dipped in detergent (detergent or stain remover) to thoroughly clean the dirt on the surface of the insulators. After drying with a dry cotton cloth, test that the insulation value of the high-voltage line to ground is higher than 1000MΩ. Otherwise, check if there are any foreign objects causing the high-voltage line to conduct electricity to the shell. After everything is normal, reinstall the maintenance doors and restart the machine. C. Low tank drainage and scale removal for the electrostatic main body: Open the maintenance door at the bottom of the main body, check whether there is carbon deposit on the electrostatic circular tube and the electrode wire. If the carbon deposit exceeds 3mm, apply a strong cleaning agent with an interface active agent and then rinse it clean with a high-pressure hot water pump. Remove the oil and accumulated water at the bottom and adjust the cycle.
Maintenance: Before conducting safety checks and maintenance on the equipment, all power sources should be disconnected and the machine should be shut down for more than 30 minutes. A dedicated person must wear protective clothing, shoes, goggles, etc. to eliminate potential hazards, conduct safety inspections, and carry out maintenance and upkeep.
