Integrated catering lampblack purification device

The utility model discloses an integrated catering lampblack purification device. A double-layer sleeve type plasma generator is arranged in an electrochemical reaction tank; the double-layer sleeve type plasma generator is composed of an inner-layer quartz sleeve and an outer-layer quartz sleeve. Conductive iron powder is filled in the inner-layer sleeve to serve as a high-voltage end, the outer-layer sleeve is wrapped by an iron wire net to serve as a low-voltage end, a high-frequency high-voltage alternating-current power supply is connected with the high-voltage end and the low-voltage end, an air inlet communicated with the interlayer gap is formed in the upper portion of the double-layer sleeve type plasma generator, and an annular micro-nano air distribution system is arranged at the bottom. An electrocatalytic oxidation electrode connected with a direct-current power supply is arranged in the electrochemical reaction tank, and a gas outlet is formed in the top of the electrochemical reaction tank.
