A kitchen fume purification device and system based on low temperature plasma technology

Abstract

The invention provides a kitchen fume purification device and system based on low-temperature plasma technology, which includes a fume pre-treatment module, a low-temperature plasma catalytic module, and a spray cleaning module connected in sequence. The metal mesh and the oil tank connected to the lower end of the metal mesh. The low-temperature plasma catalytic module includes a plurality of parallel discharge tubes. The two ends of the discharge tubes are fixed on the shell of the reactor through a porous plate. The two ends of the electrode are connected to the high-voltage electrode plate, the outside of the discharge tube is wrapped with a ground electrode, the middle of the inside is equipped with a catalyst and the tail is equipped with activated carbon. The spray cleaning module uses the heat released during the low-temperature plasma reaction to heat the cooling medium. Further, the metal mesh is blown with the cooling medium that has reached the set temperature requirement. The invention realizes the synergistic effect of the plasma and the catalyst and the reuse of waste heat, can achieve better treatment effect and ensure economical operation.

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...
