The height of the alarm mechanism is adjusted by the air pressure change input into the adsorption cylinder 2 through the adsorption inlet pipe 8 to warn the blockage degree of the adsorption structure 7; The sealing mechanism is provided with two groups, and the two groups of sealing mechanisms are respectively arranged in the two adsorption processing tanks 3. After the adsorption structure 7 is inserted into the adsorption processing tank 3, the adsorption inlet pipe 8 is sealed.

[0023] In a specific embodiment of the present invention, an air processing chamber with two adsorption processing tanks 3 is provided in the adsorption cylinder 2, and each adsorption processing tank 3 is divided into two left and right cabins by an adsorption structure 7. The cabin on the left connected to the first ventilation pipe 4 is used for air intake, and the air containing gaseous pollutants enters the adsorption processing tank 3 and is filtered by the adsorption structure 7, and the pollutants therein are adsorbed by the adsorption structure 7, and the pollutants are eliminated, and the clean air is discharged into the cabin on the other side connected to the second ventilation pipe 5. The design of the two cabins enables the device to continue filtering and ventilating the other cabin while the adsorption structure 7 in one cabin is being cleaned. The first ventilation pipe 4 is the air inlet pipe for the air to be treated in the adsorption processing tank 3, and the second ventilation pipe 5 is for filtering the air. The air outlet pipe, the adsorption base 1 is the supporting base of the adsorption system, the air pressure detection mechanism is arranged in the adsorption cylinder 2 to monitor the air flow rate in the adsorption cylinder 2, to judge the degree of blockage of toxic substances on the adsorption surface of the adsorption structure 7, the adsorption inlet pipe 8 is arranged in the adsorption cylinder 2 and is connected to the air outlet of the first ventilation pipe 4, the flow limiting and boosting pipe 12 and the air limiting pipe 20 are both hollow cylindrical structures in the middle, the adsorption inlet pipe 8 and the flow limiting and boosting pipe 12 are two integral parts, the connection between the adsorption inlet pipe 8 and the flow limiting and boosting pipe 12 is closed by the adsorption structure 7 when disassembled, and the air holes in the flow limiting and boosting pipe 12 are used to monitor the air flow rate here, and the toxic gas flows into the booster from the main air hole 9, the flow limiting air hole 11, and the air intake side hole 19. In the down pipe 21, the lifting spring 27 is always in a stretched state, and the lifting pipe 21 is pulled to block the outlet holes of the multiple outlet side holes 23. At this time, the air flowing in from the main air hole 9 can only flow into the adsorption processing tank 3 from the central flow limiting pipe 22 opened at the upper end of the lifting pipe 21. At this time, the air circulation channel is the main air hole 9, the supporting chute 10, the air inlet side hole 19, the air limiting pipe 20 and the central flow limiting pipe 22, and the central flow limiting pipe 22 limits the air flow. When there are fewer sediments in the adsorption structure 7 and the air flow rate at the left and right ends of the adsorption structure 7 is faster, the high-speed airflow flowing downward from the air inlet side hole 19 at the upper end of the lifting pipe 21 forms a pressure difference with the lower end of the lifting pipe 21, and the pressure difference pushes the lifting pipe 21 to move downward and the lifting spring 2 7 is stretched, and when the lifting tube 21 slides down, the outlet side holes 23 of the inner wall of the air limiting tube 20 are opened to increase the air circulation channel. When the adsorption structure 7 adsorbs toxic substances for a long time and blocks the adsorption holes, the air circulation speed in the adsorption structure 7 is limited. Since the blockage of the adsorption structure 7 limits the air flow rate in the flow limiting booster tube 12, the pressure difference formed by the air is reduced and is not enough to stretch the lifting spring 27. At this time, the lifting tube 21 is pulled back upward by the lifting spring 27 and blocks the outlet side holes 23. As the lifting tube 21 moves upward, the alarm mechanism is electrically connected and an alarm model is generated to remind the operator to clean the adsorption structure 7 to avoid affecting the ventilation efficiency and adsorption efficiency of the toxic air. For details, please refer to Figure 1-Figure 10Each set of alarm mechanisms includes a lifting slot 25, a lifting rod 26, a lifting spring 27, a connecting battery 28, a power connection line 29, an alarm light red alarm light 30 and an electrical connection plug 31. The lifting slot 25 is opened at the lower end of the air limiting pipe 20, the lifting rod 26 is fixedly connected to the upper end of the lifting pipe 21, the lifting rod 26 is slidably connected in the lifting slot 25 and supports the air limiting pipe 20, the lifting spring 27 is fixedly connected to the upper end of the lifting rod 26 and the upper inner wall of the lifting slot 25, the connecting battery 28 is fixedly connected to one side end of the lifting pipe 21, the power connection line 29 is fixedly connected to the output end of the connecting battery 28, the alarm light red alarm light 30 is fixedly connected to the upper end of the adsorption cylinder 2, and the electrical connection plug 31 is fixedly connected to one side end of the air limiting pipe 20 and is electrically connected to the power connection line 29.

[0024] In this embodiment: the alarm mechanism is integrated with the lifting tube 21 and moves up and down with the lifting tube 21. The lifting rod 26 is limited to slide in the lifting groove 25, so as to prevent the lifting tube 21 from falling from the air limiting tube 20. The lifting spring 27 is always in a compressed state, and the lifting spring 27 has a small elasticity and is only enough to support the lifting tube 21. The lower end of the red alarm light 30 is provided with a power connection line 29, and the end of the connection line is arranged at the electrical connection plug 31 and fixed by the electrical connection plug 31. The resilience of the lifting spring 27 pulls the lifting rod 26 and the lifting tube 21 to block the air hole of the air outlet side hole 23. When the upper end of the lifting tube 21 is impacted by the high-pressure airflow, the pressure at the upper end of the lifting tube 21 stretches the lifting spring 27. When the air circulation speed is restricted, the airflow is insufficient to stretch the lifting spring 27. When the lifting spring 27 rebounds and pulls the lifting tube 21 and the power connection line 29 upward, the power connection line 29 is inserted into the electrical connection plug 31. At this time, the red alarm light 30 is electrically connected to the connection battery 28. The connection battery 28 provides alarm power for the red alarm light 30. The connection battery 28 emits an alarm light to remind the operator to clean the adsorption structure 7.

[0025] For details, please refer to Figure 1-Figure 10 Each set of sealing mechanisms includes a sealing sleeve 14, a sealing rod 15, a connecting rod 16, a sealing spring 17 and a contact block 18.

[0026] In this embodiment: the blocking spring 17 and the lifting spring 27 are also in a stretched state, and the elastic force of the blocking spring 17 is strong enough to support the sealing sleeve 13. When the adsorption structure 7 is pulled out of the adsorption processing tank 3, the blocking spring 17 rebounds and pulls the sealing sleeve 13 upward through the connecting rod 16 until the lower inner wall of the sealing sleeve 13 blocks the lower openings of the plurality of flow-limiting air holes 11, and the sealing sleeve 13 fits the outer surface of the adsorption inlet pipe 8, and the sealing gasket 24 is arranged on the lower inner wall of the sealing sleeve 13 for sealing, and the flow-limiting booster pipe 12 will support the slide in the supporting groove 10. The groove 10 is blocked, and all the through holes in the adsorption inlet pipe 8 are blocked to cut off the air circulation of the adsorption inlet pipe 8 here. When the adsorption structure 7 is cleaned, all the circulating air flows into the adsorption treatment groove 3 on the other side for adsorption. When the cleaning is completed, the adsorption structure 7 is reinserted into the adsorption treatment groove 3, and the adsorption structure 7 contacts the contact block 18. The connecting rod 16 is pressed down by the weight of the adsorption structure 7. After the sealing sleeve 13 slides downward, the lower end opening of the flow limiting air hole 11 is reopened, and the air flows into the detection mechanism from the flow limiting air hole 11 and the air intake side hole 19, and ventilation and filtering are carried out again.

The contaminated air enters from the air inlet surface of the filter 35, diffuses to the surface of the paper core, and passes through the paper core under the action of air flow pressure, wherein large particulate matter such as aerosols cannot pass through the paper core and are filtered out.

[0035] For details, please refer to Figure 1-Figure 10 The output end of the second ventilation pipe 5 is fixedly connected to a heat exchanger 36 , and one side end of the heat exchanger 36 is fixedly connected to a vacuum pump 37 .
