1, filtration and adsorption methods: when oil fumes are activated by fiber felt activated carbon, particles are removed due to diffusion, interception, inertial collision and other reasons. The purification rate is 98% and the volume is small. It is necessary to maintain a certain length of pipeline without maintenance.
2, photolysis oxidation method: special light tube emitted light band to stimulate soot in oil fume molecules, purification rate of 90%. Most of the fumes in the exhaust gas are photolysis and oxidize to water molecules and carbon dioxide, which are taken away by the waste gas, and there is no residual sewage and oil pollution.
3, combined purification method: electrostatic method + purification method, equipment cost is high, small volume, large wind resistance, need to regularly replace filter material.
According to the purifying effect and advantages and disadvantages of the above flue gas purification equipment, please purchase according to the equipment you need.
4, centrifugal separation method, it is forced by the direction of the strong movement of the air movement, so that ash particles arrive at the deposition surface and discharge gas under inertia. However, the equipment cost is very small, the equipment is simple, the purification rate will be very low, 50%-60% is maintained once a month, but the second pollution is relatively large.
5. Liquid scrubbing method: clean oil fumes contact with absorbent solution through gas distribution device and transfer particles from gaseous phase to liquid phase (water purge and scrubbing tower cleaning process). Its purification rate is as high as 50%-90%, but it has many faults, and the nozzle is easily blocked. Therefore, daily maintenance and cleaning of waste water are needed.
6. High voltage electrostatic deposition: the clean oil fume is introduced into the high voltage electric field, and under the action of the electric field force, the particles in the fume are charged and moved to the vacuum cleaner and deposited. Its purification rate is relatively high, up to 90%, and maintenance costs are high. Once every three months, there is no two pollution.
