An oil mist collector is an environmentally friendly equipment specifically designed for industrial settings, primarily used for collecting and processing oil mists, smoke, and particulates generated from mechanical, metalworking, food processing, chemical, automotive manufacturing, electronics, aerospace, pharmaceutical, and printing industries. Its core functions include improving working conditions, protecting workers' health, extending equipment lifespan, and reducing environmental pollution.

I. Working Principle

The working principle of the oil mist purifier is primarily based on physical filtration and electrostatic adsorption technology, with some units also incorporating modules such as centrifugal separation and activated carbon adsorption, forming a multi-stage purification system. The specific process is as follows:

1. Pre-filtering stageThe air laden with oil mist first enters the pre-filter, where large oil droplets and dust are intercepted and collected into the oil trap.
2. Charging PhaseFine oil mist particles enter the charged area, becoming charged through a high-voltage electric field.
3. Dust Collection PhaseCharged particles move towards the electrode plate with the opposite polarity under the action of the electric field and adhere to the electrode plate.
4. Post-processing stageThe remaining oil mist is further purified through a secondary filter or activated carbon adsorption layer, and the clean air is exhausted by the fan.

Some equipment is equipped with an automatic cleaning system, which regularly cleans electrode plates and filter meshes using an ultrasonic cleaner or specialized cleaning agents to ensure purification efficiency.

Section II: Technical Advantages

1. Efficient PurificationThe multi-stage filtration system can remove over 95% of oil mist particles, with some equipment achieving purification efficiency up to 99%, significantly improving the air quality in the workshop.
2. Energy-saving and environmentally friendlyReclaimed liquid oil mist is recyclable, reducing coolant waste; a low-resistance design reduces fan energy consumption, lowering operating costs by 30%-50% compared to traditional equipment.
3. Safe and reliableElectrical shock protection, over-temperature prevention, and mechanical hazard prevention designs ensure safe operation of the equipment; modular structure facilitates maintenance, reducing downtime.
