Please refer to accompanying drawing 1 and accompanying drawing 2, the air inlet 1 among the present invention is installed around each food waste collection pond, guarantees to prevent the pollution body from spreading, and each production workshop 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 controlled by a pneumatic device or an electric device to open and close, and the automatic sliding gate valve 2 is used to prevent the air treatment equipment from being shut down for maintenance due to failure, so as to ensure Pollution sources are not diffused, and the rear end of the automatic slide 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, a Multiple sets of stacked first negative ion corrugated plates 4 that release 15,000 pieces/cm3, where 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 , In the present embodiment, a section of horizontal negative ion corrugated plate is combined with a section of vertical negative ion corrugated plate. During specific implementation, multiple sections can also be set 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.

The operation method of the present invention is as follows: when the kitchen waste enters the collection pool, the air inducer in the present invention starts to open the automatic slide gate valve 2 at the front end of the air collection pipeline around the pool edge, if the production workshop or other collection pools do not need When the air is being processed, the automatic slide gate valve 2 at the front end of the air collection pipe is in a closed state. If the production workshop or other collection pools also need to process the air, the automatic slide valve at the front end of the collection pipe is in an open state. 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 amount of negative ions released is 15,000/cm3 and does not need to be generated by electricity.

Under the overall irradiation of the ultraviolet light emitted by the light pipe 7, it enters the passage of the honeycomb titanium dioxide photocatalytic plate 9. After the titanium dioxide catalytic plate 9 absorbs light energy, it generates photoelectrons and photogenetic holes and generates very strong energy, which is compatible with the air. The water adsorbed on the surface reacts with oxygen to generate highly oxidative 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 air The organic pollutants contained in the air are decomposed into the most original state, especially the air has undergone several repeated photocatalytic treatments 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. To ensure that the exhausted air is fresh 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 been treated with photocatalysis and plasma automatically enters the negative ion stack at the end of the device After the negative ion treatment is performed on the corrugated plate 11 again, the residual impurities in the air are adsorbed by the activated carbon air processor and then discharged.
