When the oil fume separator is used, oil fume rises to the separating net, oil liquid molecules in the oil fume are condensed into oil drops attached to the separating net due to collision and cooling with the separating net, and the oil drops can keep a certain temperature under the action of the heater on the separating net and cannot be condensed on the surface of the separating net, so that the oil drops can smoothly slide to the bottom of the frame 10 along the surface of the separating net after being accumulated with a certain weight and flow out. Even thereby after the lampblack absorber shut down because the heater is out of work the oil stain of condensation on the separation net surface, also can be when using next time, heated by the heater to the part melts and then follows the landing of separation net. After carrying out condensation treatment for the first time to the oil contamination through the separation net, the oil smoke gets into in the oil smoke chamber 2, then filter the solid particle pollution in the oil smoke through air check 62, decompose the purification with remaining oil in the oil smoke through anion subassembly 63 thereby eliminate the oil contamination, later decompose the elimination through ozone generator to the peculiar smell pollution in the oil smoke, make the gas of discharging to outdoor clean sanitary, can not influence the atmospheric quality, and because most pollution through purifying the subassembly will be wherein and decompose then discharge outdoor together through anion and ozone, thereby also be difficult for blockking up the purification subassembly, for prior art, the ability of purifying the oil smoke is better, and separation net cleaning cycle is longer, user's clean pressure has also been alleviateed, user's use is more convenient.
