Integrated catering lampblack purification device

Abstract

The invention discloses an integrated catering lampblack purification device which is structured such that a double sleeve type plasma generator is placed in an electrochemical reaction pond; the double sleeve type plasma generator is composed of inner and outer quartz sleeves; the inner sleeve is filled with conducting iron powder as a high voltage end while the outer side of the outer sleeve iscoated with an iron gauze as a low voltage end; a high frequency high voltage alternating current power supply is connected to the high voltage end and the lower voltage end; an air inlet communicating to an interlayer gap is formed in the upper part of the double sleeve type plasma generator, and an annular micro-nano air distributing system communicating to the interlayer gap is arranged at thebottom; an electrocatalytic oxidizing electrode connected to a current direct power supply is arranged in the electrochemical reaction pond, and an air outlet is formed in the top of the electrochemical reaction pond. The integrated catering lampblack purification device purifies catering lampblack efficiently by means of a method of highly coordinating a discharge plasma and electrocatalytic oxidizing technology, solves the problems of overheating of a discharge device and difficulty to clean an attached aerosol, and has the advantages of being simple in process, compact in structure, small in occupied area, simple to maintain and the like.

Description

technical field [0001] The invention relates to the technical field of catering oil fume pollution control, in particular to an integrated catering oil fume purification device. Background technique [0002] The rapid development of urban catering industry has inevitably caused a series of environmental problems. Among them, cooking fume is one of the important pollutants affecting urban air quality. A large amount of gas, liquid and solid three-phase mixture discharged from catering sources directly endangers human health. At the same time, the volatile organic compounds contained in oil fume are one of the precursors of haze. How to properly dispose of cooking fume has become a research hotspot. At present, most of the catering oil fume treatment equipment in the market use electrostatic dust removal as the working principle. This method can effectively reduce the hazards of cooking fume, but it only realizes the adsorption and transfer of pollutants, and does not real...

AI Technical Summary

Problems solved by technology

First of all, in order to ensure the stability of discharge during work, ventilation is required to cool down the discharge device; second, after long-term operation, aerosols are easy to adhere to the discharge device. If it is not properly handled, the processing efficiency will decrease, and even an explosion will occur.
