There are many principles of fume purification,including activated carbon adsorption, UV photolysis, electrostatic adsorption, catalytic combustion, mechanical separation, fabric filtration, wet treatment, etc. However, the mainstream principle of oil fume purification is the principle of electrostatic precipitator. The principle of oil fume electrostatic precipitator with honeycomb electric collector cell and plate electric collector cell is to use the principle of high-voltage electrostatic purification,but the ionization methods are different.
The honeycomb electric collector cell is mainly use an ionization separation structure similar to the superposition of honeycomb cylinder, which is discharged by the cathode tungsten needle in the cylindrical honeycomb electric collector cell to turn the oil fume waste gas molecules into positively charged particles, which are adsorbed by the surrounding anode tube wall, so as to achieve the effect of purification effect.
Honeycomb electric collector cell and plate electric collector cell effect,which one is better? There is no absolute, if the equipment under the same air volume, the adsorption area of the honeycomb electric collector cell is larger than the plate one, so the purification effect is higher than that of the plate. However, for small particles of oil fume and low concentration of oil fume, the use of plate oil fume electrostatic precipitator has higher cost performance and high purification effect. For large particles of oil fume, dust, high concentration of oil fume, the use of honeycomb electrostatic precipitator purification effect is better, more cost-effective. Are different from different equipment electric collector cell structure and ionization adsorption principle. Generally speaking, honeycomb electrostatic precipitator is slightly more expensive than the plate one, which needs to be selected according to local environmental protection inspection standards and needs.
