WJD Series Electrostatic Oil Purifier For Particle Removal

Short Description:

Remove sub-micon particles (0.01 μm)

WJD purification accuracy is high, and the sub-micron pollutants can be removed, and the filtration accuracy can reach 0.02 microns.

System cleaning function, through the flow of electrostatic particles in the oil, all impurities such as sludge paint film and oxide attached to the oil tank, pipe wall and components are washed and adsorbed.

Working Principle


Electrostatic Adsorption Technology

The electrostatic adsorption collector uses an electrostatic generator to generate a 10KV DC high voltage, and forms a non-uniform high voltage electrostatic field in a special cylindrical collector.

The particulate pollutants in the oil are charged due to collisions, friction, and thermal molecular motion. When the charged particles move in a directional movement under the Coulomb force of the high-voltage electrostatic field, they are adsorbed on the collector. The neutral pollutant particles are polarized in the electric field, and they also make directional movement in the non-uniform electric field and are captured by the collector medium.

The fold design is adopted between the collector media to enhance the high gradient non-uniform electric field. When the oil passes through the medium, the distance between the oil and the medium of the medium collector is very small, which increases the chance of particles being adsorbed and greatly improves the purification efficiency. When the oil circulates through the collector, pollutants, sub-micron particles, and oxides are constantly adsorbed, so that the oil gradually becomes clean.

WJD doesn’t charge particles but instead using a vertical positioned electrode to generate a high potential electrostatic field inside acylinderhousing. Asnaturalg. Asnatural charged particles with oil pass upward throughelectrostatic adsorption collector, insoluble contaminants as small as submicron are forced by voltage against the pleated cellulose media and removed from oil.
