Problems solved by technology

The main advantage is that the equipment is simple and the pressure drop is small. The disadvantage is that the removal rate of small particle size particles is low, and because the particles in the oil fume have a high viscosity, the cleaning and maintenance workload is relatively large.

Abstract

This invention provides a catalytic decomposition equipment of discharging oil smoke of oil smoke machine. Catalytic oxidation reactor is electric heating room and catalytic oxidation room one body vertical structure. It is consisted by catalytic oxidation pipe, electric heating inner pipe, outlet duct, reflow device, electric heating switch and catalyst. Catalytic oxidation pipe is thin wall metal pipe, it is pushed-in air exit as drawer type, electric heating inner pipe close cling to inner wall of catalytic oxidation pipe, oxidation catalyst is filled in electric heating pipe, electric heating switch is set at top part of electric heating inner pipe, reflow device is at front part of electric heating reactor, outlet pipe is at back part of catalytic reactor. The structure is compact, blower fan is used to degas, the power source is used to heat, oil smoke can be high efficiency and low temperature catalytic processed by the heating to gas when cooking. There is no secondary pollution and low consumption and energy saving.

Description

technical field [0001] The invention relates to a catalytic decomposition treatment device for oil fume removal and exhaust, which combines two purification processes of backflow and catalytic combustion, and forms an integral purification treatment device by connecting pipelines and adjusting and controlling equipment, which is used for removing and exhausting oil fume Purify the oil fume from the exhaust outlet of the machine. Background technique [0002] The existing oil fume exhaust gas purification processes include: [0003] 1. Electrostatic degreasing: The oil fume is introduced into a high-voltage electric field, and the particles of the oil fume move to the dust collecting pole under the action of the electric field force, and are deposited and removed from the oil fume. It is characterized by compact equipment, relatively small footprint, high purification efficiency and small pressure drop. However, due to the high viscosity of the oil fume condensate on the du...
