Description

A kind of wet lampblack purification and deodorization equipment

technical field

The invention relates to the technical field of auxiliary devices for purification and treatment of oil fume, in particular to a wet type oil fume purification and deodorization equipment.

Background technique

At present, high-voltage electrostatic oil fume purifiers are generally used in China to treat such food fume exhaust gas, which belongs to a new technology of high-voltage ionization and cracking. This technology has the advantages of low equipment resistance and high processing efficiency, and has broad prospects and great potential advantages. However, because the high and low pressure body is an interdisciplinary subject including discharge physics, discharge chemistry, chemical reaction engineering and vacuum technology and other basic disciplines. Therefore, there are very few units that can master this technology in a mature way. It is reported that only a few foreign units have successfully applied 500-2000m3/h as a high and low pressure body disposal unit. Most of the propaganda that uses low temperature, high and low pressure technology to treat exhaust gas is not a low temperature, high and low pressure exhaust gas treatment technology in the true sense.

Moreover, the oil and fat are highly viscous and stick to the discharge electrode, which is not easy to clean, resulting in the inability to discharge. Food fume is a combustible oil, and a large amount of oil accumulated on the electrode can easily cause a fire, and frequent cleaning can easily affect the distance between the electrodes and the electrodes. Cause damage, resulting in unstable discharge after cleaning, and local short-circuits, thereby losing the discharge purification function. 304 material has poor electrical conductivity, other materials are corroded by hand steam and oil fume, and are easy to disconnect, etc. In summary, the high and low pressure waste gas treatment technology is not very mature, and most of the equipment that has been applied has unstable operation, consumption High energy, high maintenance and repair costs, and difficulty.
