This type of kitchen has a large production scale and can provide meals for many customers at the same time. It is composed of work areas or small kitchens with different functions. Each work area or small kitchen has a clear division of labor and is coordinated and responsible for the large-scale production of the above-mentioned enterprises or hotels;

[0003] Commercial kitchens generate a lot of oil fume waste gas during operation. The oil fume waste gas mainly comes from the process of cooking and baking food, and contains a lot of harmful substances, such as benzene, toluene, xylene, polycyclic aromatic hydrocarbons, etc. If these waste gases are not treated in time, they will cause serious harm to human health and pollute the environment. Therefore, the treatment of oil fume waste gas becomes very important.

[0004] Conventional oil fume waste gas treatment equipment has a relatively complex internal structure and cumbersome disassembly and assembly steps. In the process of treating oil fumes, more and more oil will gradually gather. If it is not handled regularly, the oil will be overloaded and leak everywhere, making it difficult to quickly handle the accumulated oil in real time.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a commercial kitchen waste gas treatment device is proposed. Utility Model Content

With the regular operation of the micro pump 503, the oil collected in the oil collecting pan 404 is quickly extracted by the oil suction pipe 504, and is injected into the interior of the oil storage tank 501 for storage in conjunction with the quick-connect valve head 502.

[0026] like Figures 1 to 5As shown, the device box 1 includes a protection box 101, a barrier net 102 and a reinforcement plate 103. The barrier nets 102 are installed on the front and rear sides of the protection box 101, and the reinforcement plates 103 are installed on the left and right sides and the upper and lower sides of the protection box 101. The connecting air duct 2 includes a flexible pipe 201, a docking frame 202 and an anti-adhesion coating 203. The front and rear ends of the flexible pipe 201 are connected to the docking frame 202, and the inner wall surface of the flexible pipe 201 is sprayed with the anti-adhesion coating 203. The barrier net 102 is used to prevent external foreign matter from entering the interior of the protection box 101. The control box 3 is electrically connected to the exhaust gas treatment component 4. The exhaust gas treatment component 4 includes a pre-filter 401, a demister 402, an electrostatic device 403 and an oil collecting tray 404. The demister 402 is arranged on one side of the pre-filter 401, and the electrostatic device 403 is arranged on the side of the demister 402 away from the pre-filter 401, and The bottom of the electrostatic device 403 is slidably connected to an oil collecting pan 404, and the exhaust gas treatment component 4 also includes a UV photolysis purifier 405 and a post-filter 406.

The structural material of the pre-filter 401 and the post-filter 406 is the same, and the surface of the defogger 402 is covered with a filter of the same material as the inner part of the pre-filter 401. The flexible pipe 201 can be flexibly bent and adjusted in different directions due to its own structural characteristics, so that it can be connected to external pipes without moving the device itself, thereby ensuring the flexibility and convenience of the device assembly. In addition, the barrier net 102 arranged on the front and rear sides of the protective box 101 can prevent small animals such as mice from entering the interior of the device box 1.

[0027] In summary, if Figures 1 to 5 As shown, when the commercial kitchen waste gas treatment device is used, the connecting air ducts 2 at the front and rear ends of the device box 1 are first used to connect with the entire kitchen waste gas discharge pipeline. During this process, the flexible pipe 201 connected to the docking frame 202 can be appropriately bent and adjusted according to the setting of the pipeline to adapt to the connection and installation of the pipeline;

[0028] When a commercial kitchen is in use, the fumes generated by cooking ingredients will be sucked into the interior of the device box 1 along the pipeline and the connecting air duct 2 under the suction of the exhaust fan. The exhaust gas treatment component 4 will operate in real time under the control and regulation of the control box 3. After passing through the barrier net 102 on one side of the protection box 101, the fumes will first enter the interior of the pre-filter 401. With the assistance of the pre-filter 401, some larger oil mist droplets and oil particles will be blocked and filtered inside the pre-filter 401, and then on the surface of the demister 402, due to mechanical collision and retention, large particles of oil mist and oil particles will be further captured. Then the airflow will directly enter the electrostatic device 403 that generates a high-voltage electrostatic field. Under the action of the high-voltage electric field, the oil The flue gas is ionized, the oil mist is charged, and most of it is degraded and carbonized, while a small number of tiny oil particles move to the positive and negative plates of the electric field under the action of the electric field force of the adsorption electric field and the airflow, are collected on the plates, and flow to the inside of the oil collecting tray 404 under the action of their own gravity. The remaining micron-level oil mist is degraded into carbon dioxide and water by the electric field, and finally discharged into clean air. At the same time, under the action of the UV photolysis purifier 405, the malodorous gas is irradiated with a special high-energy high-ozone UV ultraviolet light beam to crack the chemical bonds in the malodorous gas, thereby decomposing it into harmless or low-harmful substances, thereby removing most of the odor in the flue gas. Finally, the gas will be filtered again by the post-filter 406 to effectively filter and discharge the particulate impurities therein;

[0029] During the operation of the entire exhaust gas treatment component 4, the oil collecting component 5 connected to the bottom of the device box 1 will operate synchronously. Under the operation of the micro pump 503, the oil suction pipe 504 is used to quickly extract the oil gathered inside the oil collecting pan 404, and then transport it to the inside of the oil storage tank 501 through the quick-connect valve head 502, thereby reducing the load on the oil collecting pan 404.
