Oil fume purifier Working principles and disadvantages of wet and electrostatic treatment methods
 
Using water or other detergents, a water film and mist are formed by spraying with a nozzle to absorb oil fumes. Oil fume particles come into contact with the water mist and film sprayed from the nozzle, and through the effects of mutual inertial collision, retention, diffusion of fine particles, and mutual condensation, they flow down with the water droplets, thereby separating the oil fume ions from the airflow. This equipment has a simple structure, low investment, small footprint, low operating costs, and convenient maintenance and management.
 
Oil fume purifier Disadvantages of wet treatment: high resistance, low purification rate for submicron particles, and secondary pollution from oily wastewater.

Electrostatic treatment method for oil fume purifier
 
Under the action of an externally applied high voltage, electrons are emitted from the surface or vicinity of the negative electrode metal wire and rapidly move towards the positive electrode, colliding with and ionizing gas molecules. When oil fume waste gas passes through this high-voltage electric field, the oil fume particles become charged due to collision and capture of gas ions in a very short time, and move towards the positive electrode dust collecting plate under the action of the electric field, thereby achieving separation. This equipment has low investment, small footprint, no secondary pollution, and low operating costs. Because it is easy to capture dust particles of smaller sizes, the purification efficiency is high, reaching 85~95%. The difference between its purification mechanism and the gas method lies in the fact that the separating force is electrostatic force, which directly acts on the particles, rather than on the airflow, thus having the characteristics of low energy consumption and low resistance.
