Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of restaurant kitchen chimney emission, and particularly relates to a restaurant kitchen chimney filtering and discharging device. BACKGROUND

[0002] Kitchen fume refers to the mixture of smoke and odor generated in the cooking process, and the kitchen fume has certain harm to human health and environment. The kitchen fume contains a large amount of harmful substances such as PM2.5, PM10, carbon monoxide, carbon dioxide, nitrogen oxides, etc., which can seriously affect indoor air quality.

[0003] For example, the Chinese patent with the announcement number CN216244508U discloses a restaurant kitchen chimney filtering and discharging device, relating to the technical field of restaurant fume filtering and treatment, comprising a fume treatment box body, an inlet pipe is arranged at the outer left end of the fume treatment box body, an exhaust pipe is arranged at the outer right end of the fume treatment box body, a partition is arranged in the fume treatment box body, and four blowdown slots are formed in the upper surface of the partition from left to right. In use, the kitchen fume enters from the inlet pipe, and the atomized grease in the fume is adsorbed to the surface of the copper metal mesh plate and the surface of the metal mesh hole under the viscous adsorption effect when passing through the first, second and third fume filter plates in turn. The mesh hole number of the first, second and third fume filter plates increases in turn, so that the atomized grease in the fume can be adsorbed in stages, and the filtering effect of the atomized grease in the fume is better.

[0004] The above-mentioned patent has the following problems:

[0005] The patent has some shortcomings in use, such as: when the device filters and treats the kitchen fume, the atomized spray head installation pipe sprays cleaning liquid to clean the grease when there is a lot of grease on the three fume filter plates. However, the atomized spray head installation pipe is arranged above the fume filter plate, so that the grease below the fume filter plate cannot be completely cleaned, which will cause the filtering effect to deteriorate over a long period of time, thereby polluting the environment. In view of this, a restaurant kitchen chimney filtering and discharging device is proposed. UTILITY MODEL CONTENTS
