The device achieves efficient adsorption and uniform filtration of exhaust gas through the carefully designed activated carbon filter 12 and multiple groups of staggered settings with the mounting frame 11. At the same time, the multiple groups of staggered settings ensure that the exhaust gas can fully and evenly flow through the surface of the activated carbon, avoiding the problem of insufficient local filtration or blockage, thereby greatly improving the adsorption efficiency and deodorization effect. The locking block 8 on the box door 4 cooperates with the locking ring 10 on the filter box 1, and the design that the activated carbon filter 12 slides in the mounting frame 11 greatly simplifies the daily maintenance of the equipment and the replacement process of the activated carbon filter 12.

[0030] The filter box 1 is fixedly connected to an air supply pipe 13 at one end away from the air inlet pipe 2, and a guide fan 14 is fixedly installed in the air supply pipe 13. The air supply pipe 13 is fixedly connected to a piston cylinder 15 at one end away from the filter box 1. An extrusion rod 16 is slidably connected to the piston cylinder 15, and an electric push rod 17 is fixedly connected to one end of the extrusion rod 16.

An air supply pipe 19 is fixedly connected to the piston cylinder 15, and an end of the air supply pipe 19 away from the piston cylinder 15 is fixedly connected to a spray box 20. A spray pipe 21 is arranged in the spray box 20, and a water vapor separator 22 is arranged on the spray pipe 21. The mounting frame 11 and the activated carbon filter 12 are provided with multiple groups and are staggered. The piston head 18 is attached to the piston cylinder 15.

This multiple purification mechanism significantly improves the exhaust gas treatment effect and ensures the cleanliness of the exhaust gas.

[0031] Working principle: When using the exhaust gas deodorization device based on activated carbon adsorption, the exhaust gas is firstly sucked into the filter box 1 quickly by starting the fan 3 in the intake pipe 2. The function of the fan 3 is to provide initial power for the exhaust gas to ensure that the exhaust gas can smoothly enter the filter box 1. After entering the filter box 1, the exhaust gas first encounters the activated carbon filter 12. The activated carbon filter 12 uses its porous structure and huge specific surface area to effectively adsorb odor molecules, harmful gases and other pollutants in the exhaust gas. The multiple groups of the mounting frame 11 and the activated carbon filter 12 are staggered to ensure The exhaust gas can fully and evenly flow through the surface of the activated carbon, thereby improving the adsorption efficiency and deodorization effect. The harmful components of the exhaust gas treated by the activated carbon filter 12 have been greatly reduced. Subsequently, the exhaust gas is discharged through the air supply pipe 13. The guide fan 14 in the air supply pipe 13 continues to provide power for the exhaust gas and guides it to the subsequent treatment link. In order to further enhance the treatment effect of the exhaust gas, the air supply pipe 13 is connected to the piston cylinder 15, and the electric push rod 17 drives the extrusion rod 16 to slide back and forth in the piston cylinder 15. The piston head 18 at the end of the extrusion rod 16 is in the piston cylinder 15 moves inside, thereby generating high-pressure exhaust gas, which is transmitted to the spray box 20 through the air pipe 19 with a smaller diameter, ensuring the effective transmission of high pressure and reducing energy loss. In the spray box 20, the spray pipe 21 is connected to the external medicine source to spray out a mist of liquid medicine, which is mixed with the high-pressure exhaust gas in the spray box 20. The effective ingredients in the liquid medicine react with the residual odor and harmful substances in the exhaust gas to further purify the exhaust gas. The water vapor separator 22 is located at the top of the spray box 20, which is responsible for separating and discharging the water in the mixed gas to keep the gas In order to ensure the drying of the equipment, a drain valve 23 is provided on one side of the spray box 20 for regularly discharging the accumulated waste water to keep the inside of the equipment clean and operating normally. In addition, the locking block 8 on the box door 4 cooperates with the locking ring 10 on the filter box 1 to realize the rapid locking and opening of the box door 4, which is convenient for the daily maintenance of the equipment and the replacement of the activated carbon filter 12. The design of the spring 9 enables the locking block 8 to automatically reset when not subject to external force, thereby ensuring the reliability and sealing of the closing of the box door 4. The design of the activated carbon filter 12 sliding in the mounting frame 11 makes the replacement process simpler and faster.
