Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See attached Figure 1-Figure 4 The laptop computer metal shell surface spraying waste gas treatment device of this embodiment collects waste gas through a waste gas collection hood 1, performs preliminary filtration using multiple filter plates 4, performs deep adsorption treatment through an activated carbon plate 6, and finally performs further purification and oxidation through a spray assembly 7 and a catalytic oxidizer 8, thereby achieving comprehensive treatment of waste gas. The overall design has a compact structure and comprehensive functions, and can effectively treat waste gas generated during the spraying process to protect the environment and human health.

[0027] See attached Figure 1 The device includes an exhaust gas collection hood 1, which is a conical structure. The conical structure can better guide the exhaust gas to gather toward the center, improve the collection efficiency of the exhaust gas, and ensure that the exhaust gas can completely enter the intake pipe 2 for subsequent treatment.

[0028] See attached Figure 1 and Figure 4The exhaust gas collecting hood 1 is connected to the outside of the air intake pipe 2, and a plurality of mounting grooves 3 are provided on the air intake pipe 2 at equal intervals. Filter plates 4 are arranged in the mounting grooves 3, and the plurality of filter plates 4 are used to remove large particle impurities in the exhaust gas. The air intake pipe 2 is provided with plug holes 13 equal to the number of the mounting grooves 3 at equal intervals, and the mounting grooves 3 are connected to the plug holes 13, and the filter plate 4 is provided with plug holes 2 14 equal to the aperture of the plug holes 13, and connecting rods 15 are inserted in the plug holes 13 and the plug holes 14. When installing the filter plate 4, the filter plate 4 is inserted into the mounting groove 3. After being fully inserted, the plug holes 13 and the plug holes 2 14 are coaxially arranged. At this time, the connecting rod 15 is inserted into the plug holes 13 and the plug holes 2 14, and the connecting rod 15 is fixed with bolts to realize the connection between the filter plate 4 and the air intake pipe 2. The design of the mounting groove 3, the first plug hole 13, the second plug hole 14 and the connecting rod 15 facilitates the installation and replacement of the filter plate 4, improves the maintainability of the device, and the design of equal spacing ensures the uniform distribution of the exhaust gas and improves the filtering effect.

[0029] See attached Figure 1 The outside of the air inlet pipe 2 is connected to a treatment tube 5, the bottom of the treatment tube 5 is a conical structure, and the bottom of the treatment tube 5 is connected to a liquid outlet pipe 16. The bottom of the treatment tube 5 is designed to be a conical structure, which is conducive to the collection and discharge of liquid, and keeps the inside of the treatment tube 5 clean and running efficiently. The top of the treatment tube 5 is connected to a discharge pipe 9

[0030] See attached Figure 1-Figure 3 An activated carbon plate 6 is arranged inside the treatment cylinder 5, and the activated carbon plate 6 is a zigzag structure. When the exhaust gas flows toward the activated carbon plate 6, the zigzag structural design increases the contact area between the exhaust gas and the activated carbon plate 6, thereby improving the adsorption effect. Two mounting plates 10 are fixedly installed on the left and right sides of the treatment cylinder 5. Vertical poles 11 are fixedly installed on both sides of the activated carbon plate 6, and the vertical poles 11 are slidably connected to the two mounting plates 10 arranged on the same side. Springs 12 are arranged on the vertical poles 11 above and below the activated carbon plate 6. When the exhaust gas flows toward the activated carbon plate 6, it will collide with the activated carbon plate 6. Under the action of the spring 12, the activated carbon plate 6 will bounce back and forth between the two mounting plates 10, so that the dust adsorbed on the activated carbon plate 6 falls off, thereby extending the service life of the activated carbon plate 6.

[0031] See attached Figure 1-Figure 3A spray assembly 7 is arranged above the activated carbon plate 6, and the spray assembly 7 includes a water collecting pipe 701 fixedly installed inside the treatment tube 5. The water collecting pipe 701 is arranged horizontally, and a plurality of nozzles 702 are connected to the bottom of the water collecting pipe 701. A water storage tank 21 is arranged outside the treatment tube 5, and the water storage tank 21 provides liquid required for spraying. A liquid pump 17 is arranged outside the water storage tank 21, and an inlet pipe 18 is connected between the water storage tank 21 and the liquid inlet of the liquid pump 17. A water outlet pipe 19 is connected at the liquid outlet of the liquid pump 17, and the water outlet pipe 19 is connected to the water collecting pipe 701. The liquid pump 17 is responsible for extracting liquid from the water storage tank 21 and transporting it to the water collecting pipe 701 through the outlet pipe 19 to realize automatic spraying function. The spray assembly 7 can clean the activated carbon plate 6 regularly or as needed to ensure that the activated carbon plate 6 has effective adsorption capacity.

[0032] See attached Figure 1 A catalytic oxidizer 8 is arranged above the spray assembly 7. The catalytic oxidizer 8 uses a catalyst to catalytically oxidize VOCs into harmless substances. The top and bottom of the catalytic oxidizer 8 are connected to an air collecting hood 20. The design of the air collecting hood 20 helps to concentrate and guide the exhaust gas, ensuring that the exhaust gas can be fully processed through the catalytic oxidizer 8. At the same time, the air collecting hood 20 can also prevent the exhaust gas from escaping during the treatment process, thereby improving the treatment effect.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
