However, after the purification device runs for a period of time, more oil stains are generated on the surface of the equipment, if the purification device is not cleaned in time, the removal effect on smoke and particulate matters is reduced, and the removal rate of the purification device on VOCs is almost zero.
(2) Wet-type oil smoke purifier: besides the functions of removing oil smoke and particulate matters, a certain amount of gaseous VOCs can be removed. However, such a purification device also has a number of disadvantages, such as: when the washing water quality is poor, the spray head can be blocked, and the purification effect is directly influenced; non-water soluble VOCs cannot be treated and the flow of gas may entrain new secondary particulates; the sewage after absorbing the oil smoke needs to be effectively treated, otherwise, secondary pollution is generated.
(3) Filtration formula oil smoke purifier: most oil smoke can be removed, the purification efficiency is higher than that of a mechanical oil smoke purification device, and certain removal effect is achieved on VOCs. However, such a purification device has a high nonselective requirement for the adsorbent, and after the adsorption is saturated, if the adsorbent is not replaced in time or the desorption system is started, the content of the oil smoke in the exhaust gas is increased rapidly. In addition, the replaced spent adsorbent is a hazardous waste and needs to be disposed of.
(4) Electrostatic oil fume purification device: the purification effect to oil smoke and particulate matter is better, but electrostatic oil smoke purifier exists difficult the washing, and power consumption is higher shortcoming.
Compared with the prior art, the electrostatic oil fume purification device has better comprehensive effect, but the prior electrostatic oil fume purification device has not ideal purification efficiency on catering oil fume.
