[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

A pair of vertical plates 6 are provided on the outer side of the water tank 4, and the ends of the pair of vertical plates 6 away from each other are fixedly connected to an adjusting motor 17. Those skilled in the art can make the best choice of the model of the adjusting motor 17, such as model Y80M1-2. The insides of the water tank 1 4 and the water tank 2 5 are fixedly connected to a water pump, and the water outlet end of the water pump is fixedly connected to a nozzle 18. The upper end of the exhaust gas box 1 is fixedly connected to a pair of electric push rods 7, and those skilled in the art can make the best choice of the model of the electric push rod 7, such as ETS-50. The telescopic ends of the pair of electric push rods 7 are respectively fixedly connected to the lower ends of the pair of vertical plates 6. , the upper end of the delivery pipe 2 is fixedly connected to the regulating motor 2 8. Those skilled in the art can make the best choice for the model of the regulating motor 2 8, such as model Y80M1-2. The output end of the regulating motor 2 8 is fixedly connected to a cross bar 9, the lower end of the cross bar 9 is fixedly connected to a plurality of moving tubes 10, the lower end of the moving tube 10 is fixedly connected to a plurality of semicircular rings 11, the inner wall of the semicircular ring 11 is fixedly connected to a filter plate 12, the outer end of the delivery pipe 2 is provided with a plurality of plug-in slots 13 for movably inserting the filter plate 12, the inner wall of the delivery pipe 2 3 is fixedly connected with activated carbon 27, the outer ends of the exhaust box 1, the delivery pipe 1 2 and the delivery pipe 2 3 are all fixedly connected to the outlet pipe 14, the outer end of the exhaust box 1 is fixedly connected to the inlet pipe 15, and the upper ends of the delivery pipe 1 2, the delivery pipe 2 3, the outlet pipe 14 and the inlet pipe 15 are all fixedly connected to the switch valve 16;

[0023] The telescopic end of the regulating motor 17 moves from the outside to the inside through the vertical plate 6 and is fixedly connected to the outer ends of the water tank 1 4 and the water tank 2 5. The outer ends of the water tank 1 4 and the water tank 2 5 are fixedly connected with the water inlet pipe 19. The outer ends of the water tank 1 4 and the water tank 2 5 are provided with vertical holes, and the interior of the vertical holes is fixedly connected with a transparent plate. The transparent plate is used to facilitate personnel to observe the height of the water level in the water tank 1 4 and the water tank 2 5. The ends of the delivery pipe 1 2 and the delivery pipe 2 3 that are close to each other are both connected with the exhaust tank 1, and the water tank 1 4 and the water tank 2 5 are both connected with one end of the water inlet pipe 19.

[0024] When in use, the exhaust gas needs to be filled into the delivery pipe 1 2. The diameters of the filter holes on the multiple filter plates 12 from far to near the exhaust box 1 are reduced in sequence. The multiple filter plates 12 are used to perform multi-stage filtration on the exhaust gas to reduce the content of dust and foreign matter therein, thereby performing preliminary treatment on the exhaust gas. After that, the switch valve 16 on the delivery pipe 1 2 is opened, and the filtered exhaust gas will enter the exhaust box 1 (at this time, the switch valves 16 at the outer ends of the air inlet pipe 15 and the air outlet pipe 14 on the exhaust box 1 are both in the closed state). Before use, the exhaust gas in the water tank 1 4 and the water tank 2 5 No liquid is placed. After the exhaust gas enters the exhaust box 1, water is added to the water tank 1 4, and then the water pump is started to spray the water in the water tank 1 4 to the exhaust gas through the nozzle 18 to perform dust reduction treatment on the exhaust gas, further reducing the content of dust and foreign matter in the exhaust gas. In addition, according to the characteristics of the gas, before the gas enters the exhaust box 1, the personnel can start the electric push rod 7 to push the vertical plate 6 upward, thereby moving the water tank 1 4 and the water tank 2 5 upward, and then start the adjustment motor 17 to rotate the water tank 1 4 and the water tank 2 5 180 degrees to swap their positions (combined with Figure 2 As shown), after swapping their positions, move the water tank 1 4 and the water tank 2 5 downward until the water tank 2 5 is inserted into the exhaust gas box 1, then inject an acidic or alkaline agent into the water tank 2 5, and then start the water pump to spray the agent toward the exhaust gas, so that the agent and the acid and alkali in the exhaust gas undergo a neutralization reaction, thereby achieving the effect of purifying the exhaust gas, and then open the switch valve 16 on the delivery pipe 2 3 to allow the gas to enter the delivery pipe 2 3 (at this time, the switch valve 16 at the outer end of the outlet pipe 14 on the delivery pipe 2 3 is in a closed state), and finally use the activated carbon 27 in the delivery pipe 2 3 to adsorb the organic waste gas to achieve gas purification. The equipment can perform multi-stage purification treatment on the exhaust gas, and the cleanliness of the treated exhaust gas is high, and the operation is simple, which is convenient for personnel to use;

[0025] When it is necessary to perform specific treatment on the exhaust gas, in case 1: when only the exhaust gas needs to be filtered, the switch valve 16 on the delivery pipe 12 needs to be closed to prevent it from entering the exhaust box 1, and the exhaust gas is filtered in sequence using multiple filter plates 12. At the same time, the switch valve 16 at the outer end of the outlet pipe 14 on the delivery pipe 12 is opened to discharge the treated gas from the outlet pipe 14. After the exhaust gas is filtered by the filter plate 12, the regulating motor 2 8 needs to be started so that its output end drives the crossbar 9 and the moving pipe 10 to rotate 180 degrees counterclockwise in the vertical direction (combined with Figure 2 As shown), the filter plate 12 is removed from the delivery pipe 2, and then the filter plate 12 is cleaned, so that the device is more convenient when cleaning the filter plate 12;

[0026] Case 2: When only the exhaust box 1 is needed to treat the exhaust gas, the exhaust gas is charged into the exhaust box 1 through the air inlet pipe 15. After the exhaust gas is treated with water, acidic or alkaline reagents through the water tank 1 4 or the water tank 2 5, the switch valve 16 at the outer end of the exhaust pipe 14 on the exhaust box 1 is opened to discharge the gas through the exhaust pipe 14.

[0027] Case 3: When only the exhaust gas needs to be treated through the structure inside the delivery pipe 2 3 , the gas is injected into the delivery pipe 2 3 from the end of the delivery pipe 2 3 away from the exhaust box 1 , and the activated carbon 27 is used to adsorb the organic exhaust gas to achieve gas purification. After the gas is purified, the switch valve 16 at the outer end of the outlet pipe 14 on the delivery pipe 2 3 is opened to allow the gas to be discharged through the outlet pipe 14 ;

[0028] In summary, the equipment can treat waste gas in multiple ways, and it is convenient for personnel to choose a specific treatment method to treat waste gas according to their needs. Its practicality is ideal.

[0029] The second implementation method:

[0030] Based on the first embodiment, this embodiment adds structures such as a limiting tube 21 and a tension spring 25, and the rest of the structure remains the same as the first embodiment.

[0031] Figure 3 and Figure 5It is shown that the outer end of the conveying pipe 2 is provided with a movable plate 20, and the end of the movable plate 20 close to the conveying pipe 2 is fixedly connected to multiple limiting pipes 21, and the outer end of the semicircular ring 11 is provided with a limiting groove 22 movably inserted with the limiting pipe 21, and the outer end of the conveying pipe 2 is provided with a threaded groove, and the internal thread of the threaded groove is connected to a threaded block 23, and the end of the threaded block 23 away from the conveying pipe 2 is fixedly connected to a fixed pipe 24, and a tension spring 25 is fixedly connected to the inner wall of the fixed pipe 24, and the end of the tension spring 25 away from the fixed pipe 24 is fixedly connected to a round block 26, and the end of the round block 26 away from the tension spring 25 is fixedly connected to the movable plate 20. In the initial state, the tension spring 25 is in a stretched state, and the outer diameter of the round block 26 is equal to the inner diameter of the fixed pipe 24.

[0032] When the filter plate 12 is in the insertion groove 13, under the action of the elastic force of the tension spring 25, it will pull the round block 26 and the movable plate 20 toward the delivery pipe 12, thereby inserting one end of the limiting tube 21 into the limiting groove 22, and using the limiting tube 21 to limit the semi-circular ring 11 and the filter plate 12, thereby improving the stability of the semi-circular ring 11 and the filter plate 12 when they are in the delivery pipe 12, making them less likely to shake. When the filter plate 12 is taken out, the movable plate 20 is pulled to drive the limiting tube 21 away from the delivery pipe 12 until one end of the limiting tube 21 is removed from the limiting groove 22. At the same time, the tension spring 25 will continue to be stretched, and then the fixed tube 24 will be rotated 180 degrees counterclockwise in the vertical direction. When the fixed tube 24 rotates, the threaded block 23 will follow it to rotate in the threaded groove and move to the outside of the threaded groove, thereby moving and fixing the limiting tube 21 to the side away from the semi-circular ring 11 (combined with Figure 5 As shown), to prevent the filter plate 12 from being blocked when the filter plate 12 is taken out.

[0033] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
