[0057] A support frame 20 is fixedly installed inside the air cylinder 1. The support frame 20 is located between the mounting ring 7 and the rotating ring 6 near the mounting ring 7 and does not intersect with the stroke of all the fixed rods 9. A fan 11 is fixedly installed on the support frame 20, and the fan blades of the fan 11 are located inside the rotating ring 6.

[0058] The catalyst spraying assembly is fixedly installed inside the gas cylinder 1.

[0059] Specifically, the catalyst spraying assembly includes an inlet pipe 5, a diversion pipe 16, and a spraying pipe 19. There are two diversion pipes 16, both of which are annular pipes. The two diversion pipes 16 are coaxially fixed on the inner wall of the gas cylinder 1 and are both located between two rotating rings 6.

[0060] There are multiple spray pipes 19, which are evenly distributed along the circumference of the air cylinder 1 and are all fixedly connected to two branch pipes 16. Multiple atomizing nozzles are evenly fixed on each spray pipe 19.

[0061] There are two inlet pipes 5, each corresponding to one of the two branch pipes 16. Each inlet pipe 5 is fixed to the gas cylinder 1 and is fixedly connected to the corresponding branch pipe 16. The two inlet pipes 5 are connected to an external catalyst delivery system, which is existing technology and will not be described in detail here.

[0062] Working principle: During the exhaust gas introduction stage, the fan 11 inside the air cylinder 1 is started. The operation of the fan 11 generates negative pressure suction, which guides the exhaust gas from the electrophoresis workshop into the interior of the air cylinder 1 from the outlet of the air cylinder 1 that connects to the outlet of the electrophoresis workshop. Under the guidance of the fan 11, the exhaust gas flows along the axis of the air cylinder 1 towards the cylinder cover 3.

[0063] During the catalyst spraying stage, the catalyst delivery system connected to the inlet pipe 5 is started. The catalyst is delivered to the diversion pipe 16 through the inlet pipe 5. After being diverted by the diversion pipe 16, it is distributed to each spray pipe 19. Finally, it is atomized and sprayed out through the atomizing nozzle on the spray pipe 19, and fully mixed and contacted with the exhaust gas flowing in the gas cylinder 1.

[0064] In the photocatalytic oxidation stage, lamp source 17 is activated and emits ultraviolet light of a specific wavelength. The ultraviolet light irradiates the atomized catalyst, stimulating the catalyst to undergo a photocatalytic oxidation reaction, oxidizing and decomposing the VOCs organic pollutants contained in the exhaust gas into harmless substances such as carbon dioxide and water.

[0065] After photocatalytic oxidation treatment, the exhaust gas continues to flow towards exhaust pipe 4. It first passes through filter plate 10 to remove incompletely decomposed solid particles or impurities, and then passes through activated carbon 12 to adsorb residual trace pollutants, achieving deep purification of the exhaust gas. The purified exhaust gas is finally discharged through exhaust pipe 4 into other exhaust gas treatment towers or directly meets emission standards.

[0066] When the activated carbon 12 and filter plate 10 need to be cleaned or replaced, rotate the cylinder cover 3. The cylinder cover 3 drives the connecting rod 14 to slide along the guide groove 15, and the limiting block at the end of the connecting rod 14 slides synchronously along the limiting groove. During this process, the cylinder cover 3 drives the push block 21 to rotate synchronously. The push block 21 slides in the slide groove 22 and abuts against the connecting block 13, thereby pushing the connecting block 13 to slide along the connecting groove 8 and the slide groove 22. The arc spring 23 is compressed, and at the same time, the guide rod 24 provides guidance and limitation for the sliding of the connecting block 13. The connecting block 13 drives the rotating ring 6 to rotate in the air cylinder 1 through the fixing rod 9. The rotating ring 6 drives the support rod 18 to rotate synchronously. The sponge strip on the support rod 18 rotates accordingly to wipe and clean the dust and impurities attached to the surface of the lamp source 17, ensuring that the light intensity of the lamp source 17 is not affected. At the same time, the push rod 26 slides against the corresponding connecting block 13.

[0067] When the connecting rod 14 and the limiting block are aligned with the notch 25, the push rod 26 slides away from the corresponding connecting block 13 and onto the corresponding push block 21. At this time, the spring 27 releases its elastic potential energy and pulls the limiting cap. The limiting cap pulls the corresponding push rod 26 towards the cylinder cover 3. The push rod 26 pushes the corresponding push block 21 away from the air cylinder 1. The push block 21 pushes the cylinder cover 3 away from the air cylinder 1. The cylinder cover 3 drives the connecting rod 14, and the connecting rod 14 drives the limiting block away from the notch 25. After this, the filter plate 10 can be directly removed, the activated carbon 12 can be replaced, or the sponge strip can be removed for cleaning and replacement. After maintenance, the cylinder cover 3 is reinstalled to the air cylinder 1 through the first connecting piece. The sealing gasket seals the gap between the two to ensure the airtightness of the device.

[0068] During the reverse operation of the cylinder cover 3, a pushing force is maintained on the cylinder cover 3 to compress the sealing gasket. Simultaneously, the push block 21 pushes the corresponding push rod 26 out of the slide groove 22 and connecting groove 8, and the limiting block enters the corresponding notch groove 25. Then, under the elastic force of the arc spring 23, the push block 21 slides along the slide groove 22 until it abuts against the mounting ring 7. During this process, the push block 21 drives the cylinder cover 3, the cylinder cover 3 drives the connecting rod 14, and the connecting rod 14 drives the limiting block to slide into the corresponding limiting groove. At the same time, the connecting block 13 drives the fixing rod 9, and the fixing rod 9 drives the corresponding rotating ring 6 to rotate.

[0069] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
