[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a filtering device for exhaust gas detection, comprising a bottom plate 1, a filter tank 2 is fixedly connected to the top of the bottom plate 1, the outer wall of the filter tank 2 is fixedly connected with two spray pipes 3, the outer walls of the two spray pipes 3 are fixedly connected with a plurality of nozzles 4, a delivery pipe 5 is fixedly connected between the input ends of the two spray pipes 3, the input end of the delivery pipe 5 is fixedly connected with a water pump 6, the input end of the water pump 6 is fixedly connected with a water tank 7, the input end of the water tank 7 is fixedly connected with a drain pipe 8, and the output end of the filter tank 2 is fixedly connected with the input end of the drain pipe 8, the outer wall of the filter tank 2 is fixedly connected with an air inlet pipe 9, the inner wall of the filter tank 2 is fixedly installed with two baffles 10, the top of the filter tank 2 is fixedly connected with a first connecting pipe 11, the inner wall of the first connecting pipe 11 is fixedly installed with a wire mesh demister 12, the output end of the first connecting pipe 11 is fixedly connected with a blower 13, the output end of the blower 13 is fixedly connected with a second connecting pipe 14, and the output end of the second connecting pipe 14 is fixedly connected with a filter box 15.

[0024] The effect achieved by the entire embodiment 1 is that when the exhaust gas enters the filter tank 2, the water pump 6 is first started, the water pump 6 draws washing liquid from the water tank 7 and pressurizes it, and then the pressurized washing liquid is transported to the two spray pipes 3 through the delivery pipe 5. The outer walls of the two spray pipes 3 are fixedly connected with multiple nozzles 4. Under the action of these nozzles 4, the washing liquid is sprayed out in the form of fine droplets, which are fully in contact with the exhaust gas, thereby dissolving or absorbing harmful substances in the exhaust gas. Subsequently, the staff starts the blower 13. The strong suction force generated by the blower 13 causes the exhaust gas to move from bottom to top inside the filter tank 2. The sprayed exhaust gas first encounters the obstruction of two baffles 10, and the water vapor in the exhaust gas condenses on the baffles 10 to form Water droplets and deposited water vapor fall to the bottom of the filter tank 2 along the baffle 10 under the action of gravity, and then the exhaust gas enters the first connecting pipe 11. The wire mesh demister 12 installed on the inner surface wall of the first connecting pipe 11 further removes water vapor and residual liquid in the exhaust gas to improve the purity of the exhaust gas. The preliminarily filtered exhaust gas then enters the filter box 15. In the filter box 15, the exhaust gas is first filtered by the primary filter 18 to remove larger particles and impurities. Then, the medium efficiency filter 19 further filters smaller particles and suspended matter in the exhaust gas. Finally, the exhaust gas passes through the activated carbon filter 20, and the adsorption capacity of the activated carbon is used to remove harmful gases and odors in the exhaust gas, so that the exhaust gas meets the emission standards or further treatment requirements.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, three mounting frames 16 are fixedly installed on the inner surface wall of the filter box 15, and a group of springs 17 are fixedly installed on the inner surface walls of the three mounting frames 16. A primary filter 18 is fixedly connected between one side of the outer wall of one group of the three groups of springs 17, a medium-efficiency filter 19 is fixedly connected between one side of the outer wall of one group of the three groups of springs 17, and an activated carbon filter 20 is fixedly connected between one side of the outer wall of one group of the three groups of springs 17. Two fixed plates 21 are fixedly installed on one side of the outer wall of the filter box 15, a rotating rod 22 is movably inserted between the inner surface walls of the two fixed plates 21, and three protrusions 23 are fixedly sleeved on the outer wall of the rotating rod 22. A driving motor 24 is fixedly connected to one side of the outer wall of the rotating rod 22, and an exhaust pipe 25 is fixedly connected to one side of the outer wall of the filter box 15.

[0026] The effect achieved by the entire embodiment 2 is that after the filtering device has been running continuously for a period of time, the filtering performance of the primary filter 18, the medium filter 19 and the activated carbon filter 20 will gradually decrease. This is because their filtering media will gradually accumulate particulate matter, dust and other pollutants, resulting in pore blockage, thereby reducing the filtering efficiency. In order to restore the performance of the filter, the drive motor 24 is started at this time, and the drive motor 24 drives the rotating rod 22 to rotate through the output shaft, and the three protrusions 23 fixedly mounted on the outer wall of the rotating rod 22 will perform a circular motion accordingly. During the rotation process, the three protrusions 23 will contact the outside of the primary filter 18, the medium filter 19 and the activated carbon filter 20 in turn, generating periodic impact and vibration. This impact and vibration can effectively remove pollutants accumulated on the filter, loosen and separate particulate matter attached to the filter medium by physical means, and make it fall off the filter. In addition, a group of springs 17 are fixedly connected to one side of the outer wall of the primary filter 18, the medium filter 19 and the activated carbon filter 20. The three groups of springs 17 will produce elastic deformation under the impact of the protrusion 23. This deformation not only enhances the vibration effect, but also helps the filter to quickly return to its initial position after the vibration ends, thereby ensuring the stability and sealing of the filter. Through this regular cleaning mechanism, the filtering performance of the primary filter 18, the medium filter 19 and the activated carbon filter 20 can be restored, thereby ensuring that the entire filtering device can continuously and efficiently treat exhaust gas.

[0027] Working principle: After the device is powered on, the exhaust gas first enters the filter tank 2 through the air inlet pipe 9. At this time, the control system starts the water pump 6 and the blower 13. The water pump 6 extracts the washing liquid from the water tank 7 and pressurizes it so that the washing liquid flows into the two spray pipes 3 through the delivery pipe 5. Under the action of multiple nozzles 4, the washing liquid is evenly sprayed in the form of mist and fully contacts with the exhaust gas, thereby dissolving or adsorbing the harmful substances in the exhaust gas. At the same time, after the blower 13 is started, a strong suction force is generated to guide the exhaust gas to flow from bottom to top inside the filter tank 2. The exhaust gas treated by spraying is first blocked by two baffles 10. The water vapor in the exhaust gas condenses into water droplets on the baffles 10. The deposited water vapor falls to the bottom of the filter tank 2 under the action of gravity. Subsequently, the exhaust gas enters the first connecting pipe 11. The wire mesh demister 12 installed on the inner surface wall of the first connecting pipe 11 further removes the remaining water vapor and droplets in the exhaust gas to ensure the dryness of the exhaust gas. The exhaust gas that has been preliminarily treated then enters the filter box 15. Inside the filter box 15, the primary effect The filter 18 first removes large particles and impurities in the exhaust gas, and then the medium efficiency filter 19 further removes smaller particles and suspended matter. Finally, the activated carbon filter 20 uses its adsorption performance to remove harmful gases and odors in the exhaust gas, so that the exhaust gas meets the emission standards or meets the requirements of further treatment. With the use of the filtering device, the filtering performance of the primary filter 18, the medium efficiency filter 19 and the activated carbon filter 20 will gradually decrease. In order to restore their performance, the control system starts the drive motor 24, and the output end of the drive motor 24 drives the rotating rod 22 to rotate, thereby rotating the three protrusions 23. During the rotation process, the protrusions 23 will periodically impact the primary filter 18, the medium efficiency filter 19 and the activated carbon filter 20, causing vibration. At the same time, the three groups of springs 17 are deformed during the vibration process, which not only enhances the vibration effect, but also ensures the reset and stability of the filter after vibration. Through this cleaning mechanism, the performance of the filter is restored, ensuring the efficient operation of the filtering device.
