Please refer to accompanying drawing 1 and accompanying drawing 2, the air inlet 1 in the utility model is installed around each kitchen garbage collection pool, guarantees to prevent the pollution from spreading, and each production section and the upper two sides of the production workshop that may overflow peculiar smell The rear end of each air inlet 1 is equipped with an automatic sliding gate valve 2. The automatic sliding gate valve 2 is opened and closed through a pneumatic device or an electric device. The automatic sliding gate valve 2 is used to prevent the air handling equipment from being shut down for maintenance due to failure. To ensure that the pollution source does not spread, the rear end of the automatic sliding gate valve 2 is connected to the air delivery pipeline 3, and an anion corrugated plate 4 is arranged in the air delivery pipeline 3. In this embodiment, the front end of the air delivery pipeline 3 is installed at a distance of 30cm to 80cm from the inlet end. There are multiple sets of stacked first negative ion corrugated plates 4 releasing 15,000 pieces/cm3. Here, the negative ion corrugated plates 4 are installed horizontally, and a vertically installed stacked negative ion corrugated plate is installed at the rear end of the horizontally installed negative ion corrugated plates. Plate, in the present embodiment, with one section of horizontal anion corrugated plate and one section of vertical anion corrugated plate to form, during concrete implementation, can also be provided with multiple sections respectively according to actual needs. In the present embodiment, each section of negative ion corrugated plate includes more than one piece, and the distance between the plates is 10mm. The tail end of the air delivery pipeline 3 is connected with a photocatalytic main processor 5. After the air is processed through the negative ion area, the induced draft fan installed in the photocatalytic main processor 5 guides the air to the tail end of the air supply pipeline, and then enters Inside the main photocatalytic processor 5. In this embodiment, the photocatalytic main processor 5 is provided with an air channel, the air channel is a Z-shaped air channel, and the inside of the Z-shaped air channel is a Z-shaped guide plate 6, and the Z-shaped guide plate 6 is a mirror aluminum alloy plate , used to reflect the light emitted by the light source of the ultraviolet light pipe 7 in the Z-shaped air passage, and several ultraviolet light pipes 7 with a light emitting wavelength of 253nm-258nm are installed in the Z-shaped air passage, and the back of each ultraviolet light pipe 7 Both are equipped with a glossy reflector 8, which is used to reflect the light source emitted by the ultraviolet light pipe 7 into the air passage, so as to maximize its effect.

In this embodiment, the activated carbon air filter 12 is provided with activated carbon in the shell, and performs final activated carbon adsorption on the gas.

The operation method of the utility model is as follows: when the kitchen waste enters the collection pool, the air inducer in the utility model is activated, and the automatic slide gate valve 2 at the front end of the air collection pipeline around the pool is opened. If the production workshop or other collection pools When there is no need to process the air, the automatic slide gate valve 2 at the front end of the air collection pipe is closed. If the production workshop or other collection pools also need to process the air, the automatic slide valves at the front end of the collection pipe are all open. Due to the function of the air inducer, the air containing bacteria and peculiar smell enters the negative ion laminated corrugated plate 4 in the pipeline through the gate valve 2 for treatment. The distance between the corrugated plates is 5mm-10mm, and the negative ion laminated corrugated plate 4. The amount of negative ions released is 15,000/cm3 and does not need to be powered on. The bacteria and odors with positive ions in the passing air are captured and killed for the first time and then settled.

After entering the main processor, the gas moves in a Z-shaped direction from bottom to top, and the gas is installed on the four walls of the Z-shaped channel. Under the overall irradiation of the ultraviolet light emitted by the ultraviolet light pipe 7, it enters the channel of the honeycomb titanium dioxide photocatalytic plate 9, and after the titanium dioxide catalytic plate 9 absorbs the light energy, it generates photo-generated electrons and photo-generated holes and generates very strong energy, which is consistent with The water adsorbed on the surface of the air reacts with oxygen to generate very active oxidizing hydroxyl radicals and superoxide ion radicals. These abilities are far higher than the strength of the molecular chains of general organic pollutants. Therefore, when the air enters the Z-shaped channel , the organic pollutants in the air are decomposed into the most original state, especially the air has undergone several times of repeated photocatalytic treatment in the Z-shaped air channel, the bacteria and viruses in the air have been effectively removed, and the odor in the air is degraded at the same time, In order to further ensure that the exhausted air is clean and qualified, a plasma generator 13 is installed at the corner of the Z-shaped air channel to enhance the degradation and removal of pollutants, and the air that has undergone combined photocatalytic and plasma treatment automatically enters the air at the end of the device. After negative ion laminated corrugated plate 11 is subjected to negative ion treatment again, residual impurities in the air are adsorbed by activated carbon air processor and then discharged. At this time, the discharged gas is odorless, sterile, free of solid particles, non-toxic and harmful, and fresh and clean. the

The utility model can centrally collect and process the peculiar smell overflowed from each section and the air in the whole workshop during the kitchen waste treatment process, continuously and efficiently eliminate harmful microorganisms, bacteria and viruses, and degrade the collected air. The gas discharged at this time is odorless, sterile, free of solid particles, non-toxic and harmful, and fresh and clean. the
