[0035] The right side of the connecting plate 8 is fixedly connected with a cleaning plate 11. When the motor 9 drives the gear 10 to rotate, the cleaning plate 11 can reciprocatingly wipe and clean the surface of the filter screen 2, effectively removing the dust and impurities accumulated on the filter screen 2, ensuring that the filtering efficiency of the filter screen 2 is always at a high level. The right side of the shell 1 is fixedly connected with a connecting block 12, which is the connecting part of the shell 1 and the shell 2 20. The inside of the connecting block 12 is provided with a blocking groove 13, which provides installation space for the internal slowing down assembly. The inside of the blocking groove 13 is slidably connected with a slowing down assembly.

[0036] Referring to Figure 3 and Figure 5 , the slowing down assembly includes a baffle 14, which is a core airflow regulating component and can smoothly slide in the blocking groove 13. The rear side of the baffle 14 is fixedly connected with a tooth 15, which is engaged with the gear 17 to move. The inner wall of the blocking groove 13 is fixedly connected with a motor 16, which is a power source for controlling the movement of the baffle 14. The driving end of the motor 16 is fixedly connected with a gear 17, and the teeth of the gear 17 are engaged with the teeth 15 on the rear side of the baffle 14. This ensures that the power of the motor 16 can be effectively transmitted to the baffle 14, so that it moves in the expected way. The right side of the connecting block 12 is fixedly connected with a guide block 18, which mainly provides a stable flow channel for the airflow. The inside of the connecting block 12, i.e. the inside of the guide block 18, is provided with a flow port 19 through which the exhaust gas flows.

[0037] Referring to Figures 1 to 3 , the outside of the gear 10 is engaged with the outside of the fixed column 3. When the motor 9 starts and drives the gear 10 to rotate, the gear 10 rolls stably along the tooth groove of the fixed column 3. Due to the precision of the engagement, the rotational power of the motor 9 can be efficiently converted into linear motion power, thereby driving the support plate 5 and other components connected thereto to move accurately. The outside of the support plate 5 is slidably connected to the left side of the filter screen 2, so that the cleaning plate 11 on the support plate 5 can evenly cover the surface of the filter screen 2, ensuring that the filter screen 2 is cleaned comprehensively and effectively, and also ensuring the stability and reliability of the entire structure during movement.

[0038] The outer sliding connection of the motor 9 is on the left side of the sliding groove 6, which ensures that the sliding range of the motor 9 is within the predetermined interval, preventing excessive displacement and affecting the normal operation of the entire cleaning assembly. The right side of the cleaning plate 11 is in contact with the left side of the filter screen 2, effectively removing dirt and impurities on the surface of the filter screen 2. The right side of the adapter block 12 is fixedly connected with the shell 20. The shell 20 is the key area during purification. The inner wall of the cavity of the shell 20 is fixedly connected with the heat exchange area 21. The heat exchange area 21 can exchange heat with a specific cooling or heating medium, thereby adjusting the temperature of the gas to reach a temperature condition suitable for subsequent catalytic reaction.

[0039] The right side of the heat exchange area 21 is fixedly connected with the metal catalyst net 22. The metal catalyst net 22 can accelerate the oxidation decomposition reaction of VOCs under specific temperature and gas environment, converting it into harmless carbon dioxide, water and other substances. The right side of the shell 20 is fixedly connected with the exhaust port 23. The purified gas can be smoothly discharged to the external environment through the exhaust port 23. The outer sliding connection of the baffle 14 is in the inner part of the flow-through port 19, which ensures the free sliding of the baffle 14 in the flow-through port 19 and effectively prevents gas leakage. The outer part of the gear tooth 15 is engaged with the outer part of the gear 17. The engagement of the gear tooth 15 and the gear 17 enables the baffle 14 to slide smoothly along the inner wall of the flow-through port 19. The outer sliding connection of the baffle 14 is in the inner part of the adapter block 12, which provides a corresponding guide rail and limiting structure for the sliding of the baffle 14. The bottom of the baffle 14 is in contact with the inner wall of the flow-through port 19. By moving the baffle 14, the speed of the airflow can be accurately controlled.

[0040] Working principle: in use, the exhaust gas enters the inner part of the shell 1 through the air inlet, and is filtered by the filter screen 2. When the filter screen 2 is used for a long time, the motor 9 is started to drive the gear 10, which is engaged with the fixed column 3 to drive the gear 10 to roll along the tooth groove of the fixed column 3, thereby driving the support plate 5 to slide in the filter screen 2 through the sliding block 4, and then driving the cleaning plate 11 to clean the surface of the filter screen 2. When moving to the top, the gear 10 is engaged with the fixed column 3, and then the sliding plate 7 slides in the inner part of the sliding groove 6, thereby driving the motor 9 and the gear 10 to slide, achieving the reciprocating motion of the cleaning plate 11, which can effectively remove the dust and impurities accumulated in the filter screen 2, ensuring its filtering efficiency. After filtration, the activated carbon plate is used to adsorb the exhaust gas, and after adsorption, the adapter block 12 is used to enter the inner part of the shell 20.

[0041] When the exhaust gas flow rate is too fast, the catalyst material of the metal catalyst net 22 is prevented from being blown off. The gear two 17 is driven to rotate by the motor two 16. Since the gear two 17 is engaged with the teeth 15 on the rear side of the baffle 14, the baffle 14 is driven to slide in the blocking groove 13 and the flow-through opening 19 of the connecting block 12, so that the control of the exhaust gas flow rate is achieved, and the influence on the metal catalyst net 22 is reduced. After the exhaust gas enters the shell two 20, the temperature of the exhaust gas is adjusted by heat exchange with the specific medium in the heat exchange area 21. After the temperature of the exhaust gas is adjusted to the condition suitable for the catalytic reaction, the oxidation decomposition reaction occurs in the metal catalyst net 22, the exhaust gas is converted into harmless carbon dioxide, water and other substances, and finally the purified gas is smoothly discharged to the external environment through the exhaust port 23, so that the effective purification treatment of the exhaust gas is achieved.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or to the equivalent replacement of some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
