Low-temperature plasma technique-based kitchen fume purification device and system

Abstract

The invention provides a low-temperature plasma technique-based kitchen fume purification device and system. The low-temperature plasma technique-based kitchen fume purification device comprises a fume pretreatment module, a low-temperature plasma catalytic module and a spray-washing module; the fume pretreatment module comprises a metal net slantly arranged on the front side of a reactor and an oil groove connected to the lower end of the metal net; the low-temperature plasma catalytic module comprises a plurality of discharge tubes connected in parallel, two ends of the discharge tubes are fixed on a shell of the reactor through perforated plates, a high-voltage electrode is arranged in the axis, two ends of the high-voltage electrode are connected with high-voltage electrode plates, the outer side of the discharge tubes is wrapped by grounding electrodes, a catalyst is arranged in the middle position in the discharge tubes, and activated carbon is arranged on the tail part; the spray-washing module heats a cooling medium by using heat generated in the low-temperature plasma reaction process, and further the cooling medium which meets a set temperature requirement is used for purging the metal net. The synergistic effect of the plasma and the catalyst and reuse of afterheat are realized, a relatively good treatment effect is achieved, and economic operation is ensured.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a kitchen fume purification device and system based on low-temperature plasma technology. Background technique [0002] During the 13th Five-Year Plan period, facing the increasingly severe air pollution situation, the state actively introduced relevant policies to increase the control and treatment of air pollutants. Kitchen fumes in the catering industry have become one of the air pollutants that cannot be ignored. Kitchen fumes mainly contain small solid particles, small liquid droplets and volatile organic compound gases (VOCs). disease. Currently on the market, there are many types of oil fume purification equipment, which can be roughly divided into three types: filter type, electrostatic deposition type and spray absorption type according to their working principles. However, the inventors of the present invention have found through research that the filter typ...
