The flow-limiting pipe is fixedly connected to the lower end of the flow-limiting and pressurizing pipe. The rising pipe is slidably connected inside the flow-limiting pipe. The central flow-limiting pipe is opened at the upper end of the rising pipe. The exhaust side hole is opened on the inner circumferential wall of the flow-limiting pipe. An alarm mechanism is provided, consisting of two sets, each connected to a pressure detection mechanism. The height of the alarm mechanism is adjusted by changing the pressure inside the adsorption cylinder via the intake pipe to provide an early warning of the blockage degree of the adsorption structure. A sealing mechanism is provided, consisting of two sets, each located in one of the two adsorption treatment tanks. After the adsorption structure is inserted into the adsorption treatment tank, the adsorption intake pipe is sealed.

[0008] As a preferred embodiment of the present invention, each alarm mechanism includes a lifting groove, a lifting rod, a lifting spring, a connecting battery, a power connection line, a red alarm light, and an electrical connection plug. The lifting groove is located at the lower end of the gas limiting tube, the lifting rod is fixedly connected to the upper end of the lifting tube, the lifting rod is slidably connected in the lifting groove and supports the gas limiting tube, the lifting spring is fixedly connected to the upper end of the lifting rod and the upper inner wall of the lifting groove, the connecting battery is fixedly connected to one side of the lifting tube, the power connection line is fixedly connected to the output end of the connecting battery, the red alarm light is fixedly connected to the upper end of the adsorption cylinder, and the electrical connection plug is fixedly connected to one side of the gas limiting tube and electrically connected to the power connection line.

[0011] As a preferred embodiment of the present invention, the lower inner walls of both adsorption treatment tanks are fixedly connected with limit support blocks.

[0012] As a preferred embodiment of the present invention, a surface cooler is fixedly connected to the input end of the first vent pipe, and a cooling pipe is provided inside the surface cooler.

[0013] As a preferred embodiment of the present invention, a filter is fixedly connected to one end of the cooling pipe, and a paper core filter unit is provided inside the filter.

[0014] In a preferred embodiment of the present invention, a heat exchanger is fixedly connected to the output end of the second vent pipe, and a vacuum pump is fixedly connected to one side of the heat exchanger.

[0015] As a preferred embodiment of the present invention, the adsorption structure is a drawer-type structure made of activated carbon fiber material.

[0016] The method of using the regenerative filtration ventilation device of the present invention includes the following steps:

[0017] S1. The device uses a filter as the input end and a vacuum pump as the output end. Temperature and humidity are adjusted in the surface cooler, and adsorption and purification are completed in the adsorption cylinder. The vacuum pump provides air circulation power. The three parts of temperature and humidity adjustment, adsorption and purification and desorption and regeneration are completed in the filter, surface cooler, adsorption cylinder and heat exchanger.

[0018] S2. When the filter holes in the adsorption structure become clogged to a certain extent after a long period of filtration, it affects the airflow speed on both sides of the adsorption structure, thereby reducing the air pressure at the top of the lifting pipe. The lifting pipe is pulled upward by the lifting spring and slides upward to block the through hole of the air outlet side hole. During the lifting process, the power connection line is electrically connected to the red alarm light, triggering the red alarm light to sound.

[0019] S3. The operator pulls the adsorption structure out of the adsorption treatment tank for cleaning. The sealing mechanism seals the adsorption inlet pipe at the same time as the adsorption structure is pulled out of the adsorption treatment tank. The ventilation mechanism ventilates and filters through another set of adsorption treatment tanks. After the adsorption structure is cleaned, it is reinserted into the adsorption treatment tank and the adsorption inlet pipe is opened for ventilation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This device is equipped with a pressure detection mechanism and an alarm mechanism. When the adsorption structure becomes blocked, the change in airflow will trigger the alarm mechanism. The red alarm light will be lit by physical movement, prompting the operator to clean or replace the adsorption material in time. This not only ensures the continuous and efficient operation of the system, but also greatly reduces the risk of performance degradation due to negligence.

[0022] 2. This device not only includes a preliminary filter and surface cooler to regulate the quality, temperature, and humidity of the air entering the system, but also features an adsorption structure made of activated carbon fiber material inside the adsorption cartridge, which can effectively remove harmful substances from the air. Furthermore, by connecting to a heat exchanger and vacuum pump, the adsorption material can be regenerated after use, ensuring its long-term efficient operation.

[0023] 3. Through this device, the pressing block set at the lower end of the adsorption sealing plate cooperates with the contact block in the sealing mechanism to automatically open and close the adsorption air inlet pipe when the adsorption structure is inserted into or pulled out of the adsorption treatment tank, preventing untreated air from entering the system. At the same time, the design of the limiting support block ensures the positional stability of the adsorption structure during operation, enhancing the safety and reliability of the overall system.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-10 The present invention provides the following technical solutions:

[0038] A regenerative filtration and ventilation device includes: an adsorption base 1; and an adsorption cylinder 2, which is fixedly connected to the upper end of the adsorption base 1.

[0039] The adsorption mechanism includes an adsorption treatment tank 3, a first vent pipe 4, a second vent pipe 5, an adsorption sealing plate 6, and an adsorption structure 7. There are two adsorption treatment tanks 3, adsorption sealing plates 6, and adsorption structures 7. The adsorption treatment tank 3 is located at the upper end of the adsorption cylinder 2. The first vent pipe 4 and the second vent pipe 5 are both fixedly connected to the upper end of the adsorption cylinder 2. The two adsorption structures 7 are slidably connected in the two adsorption treatment tanks 3 respectively. The two adsorption sealing plates 6 are fixedly connected to the upper ends of the two adsorption structures 7 respectively.

[0040] The air pressure testing mechanism consists of two sets. Each set includes an adsorption inlet pipe 8, a main air port 9, a support groove 10, a flow-limiting air port 11, a flow-limiting pressurizing pipe 12, a sealing sleeve 13, an inlet side port 19, a flow-limiting pipe 20, a lifting pipe 21, a central flow-limiting pipe 22, and an outlet side port 23. Multiple flow-limiting air ports 11, inlet side ports 19, and outlet side ports 23 are provided. The adsorption inlet pipe 8 is located at the output end of the first ventilation pipe 4 and on the upper inner wall of the adsorption treatment tank 3. The main air port 9 is located at the upper end of the adsorption inlet pipe 8, and the support groove 10 is located on the adsorption inlet pipe. At the lower end of the adsorption inlet pipe 8, multiple flow-limiting air holes 11 are opened at the lower end of the adsorption inlet pipe 8, the flow-limiting and pressure-boosting pipe 12 is slidably connected to the support groove 10, the sealing sleeve 13 is fixedly connected to the circumferential surface of the flow-limiting and pressure-boosting pipe 12 and slidably connected to the outer circumferential surface of the adsorption inlet pipe 8, multiple air inlet side holes 19 are opened on the inner circumferential wall of the flow-limiting and pressure-boosting pipe 12, the air-limiting pipe 20 is fixedly connected to the lower end of the flow-limiting and pressure-boosting pipe 12, the lifting pipe 21 is slidably connected to the air-limiting pipe 20, the central flow-limiting pipe 22 is opened at the upper end of the lifting pipe 21, and the air outlet side hole 23 is opened on the inner circumferential wall of the air-limiting pipe 20.

[0041] The alarm mechanism consists of two sets, each connected to a pressure detection mechanism. The height of the alarm mechanism is adjusted by the pressure change inside the adsorption cylinder 2 via the adsorption inlet pipe 8 to provide early warning of the degree of blockage in the adsorption structure 7.

[0042] The sealing mechanism consists of two sets, which are respectively located in the two adsorption treatment tanks 3. After the adsorption structure 7 is inserted into the adsorption treatment tank 3, it seals the adsorption inlet pipe 8.

[0043] In a specific embodiment of the present invention, the adsorption cylinder 2 is provided with two adsorption treatment tanks 3 for air treatment. Each adsorption treatment tank 3 is divided into two chambers, left and right, by an adsorption structure 7. The left chamber, connected to the first ventilation pipe 4, is used for air intake. Air containing gaseous pollutants enters the adsorption treatment tank 3 and is filtered by the adsorption structure 7. The pollutants are adsorbed by the adsorption structure 7 and eliminated. The clean air is discharged into the other chamber, connected to the second ventilation pipe 5. The design of the two chambers allows the device to continue filtering and ventilating the other chamber while the adsorption structure 7 in one chamber is being cleaned. The first ventilation pipe 4 is the air intake pipe for the air to be treated in the adsorption treatment tank 3, and the second ventilation pipe 5 is for filtering the air. The air outlet pipe and the adsorption base 1 serve as the support base for the adsorption system. A pressure detection mechanism is located inside the adsorption cylinder 2 to monitor the airflow velocity within the cylinder, thus determining the degree of blockage by toxic substances on the adsorption surface of the adsorption structure 7. The adsorption inlet pipe 8 is located inside the adsorption cylinder 2 and connects to the outlet of the first vent pipe 4. Both the flow-limiting and pressure-boosting pipe 12 and the flow-limiting pipe 20 are hollow cylindrical structures. The adsorption inlet pipe 8 and the flow-limiting and pressure-boosting pipe 12 are treated as two separate units. The connection between the adsorption inlet pipe 8 and the flow-limiting and pressure-boosting pipe 12 is sealed at this point during disassembly via the adsorption structure 7. The air vents within the flow-limiting and pressure-boosting pipe 12 are used to monitor the airflow velocity at this location. Toxic gas flows into the system from the main air vent 9, the flow-limiting air vent 11, and the inlet side vent 19. Inside the descending pipe 21, the lifting spring 27 is always stretched, pulling the descending pipe 21 to block the air outlets of multiple air outlet side holes 23. At this time, the air flowing in from the main air hole 9 can only flow into the adsorption treatment tank 3 through the central flow-limiting pipe 22 opened at the upper end of the descending pipe 21. At this time, the air flow channel is the main air hole 9, the support slide 10, the air inlet side hole 19, the air limiting pipe 20, and the central flow-limiting pipe 22. The central flow-limiting pipe 22 restricts the air flow. When there are few deposits in the adsorption structure 7 and the air flow velocity at the left and right ends of the adsorption structure 7 is relatively fast, the high-speed airflow flowing downward from the air inlet side hole 19 at the upper end of the descending pipe 21 forms a pressure difference with the lower end of the descending pipe 21. The pressure difference pushes the descending pipe 21 to move downward and pulls the lifting spring 27. 7. When the lifting pipe 21 slides down, it opens the air outlet holes 23 on the inner wall of multiple air-limiting pipes 20, increasing the airflow channel. When the adsorption structure 7 adsorbs toxic substances for a long time and blocks the adsorption holes, it restricts the airflow speed within the adsorption structure 7. Due to the blockage of the adsorption structure 7, the airflow velocity within the flow-limiting booster pipe 12 is also limited, reducing the air pressure difference to the point where it is insufficient to stretch the lifting spring 27. At this time, the lifting pipe 21 is pulled upwards by the lifting spring 27, blocking the multiple air outlet holes 23. As the lifting pipe 21 moves upwards, the alarm mechanism is electrically connected, generating an alarm signal to remind the operator to clean the adsorption structure 7, thus avoiding affecting the ventilation and adsorption efficiency of toxic air. For details, please refer to [link to relevant documentation]. Figures 1-10Each alarm mechanism includes a lifting groove 25, a lifting rod 26, a lifting spring 27, a connecting battery 28, a power connection line 29, a red alarm light 30, and an electrical connection plug 31. The lifting groove 25 is located at the lower end of the gas limiting tube 20. The lifting rod 26 is fixedly connected to the upper end of the lifting tube 21. The lifting rod 26 is slidably connected inside the lifting groove 25 and supports the gas limiting tube 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 groove 25. The connecting battery 28 is fixedly connected to one side of the lifting tube 21. The power connection line 29 is fixedly connected to the output end of the connecting battery 28. The red alarm light 30 is fixedly connected to the upper end of the adsorption cylinder 2. The electrical connection plug 31 is fixedly connected to one side of the gas limiting tube 20 and electrically connected to the power connection line 29.

[0044] 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 confined within the lifting groove 25 to slide, thereby preventing the lifting tube 21 from falling out of the gas limiting pipe 20. The lifting spring 27 is always in a compressed state, and the elasticity of the lifting spring 27 is only enough to support the lifting tube 21. The lower end of the red alarm light 30 is provided with a power connection wire 29, and the end of the connection wire is fixed at the electrical connection plug 31. The rebound force 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 a high-pressure airflow, the pressure at the upper end of the lifting tube 21 stretches the lifting spring 27. When the airflow speed is restricted, making the airflow insufficient to stretch the lifting spring 27 further, the lifting spring 27 rebounds and pulls the lifting tube 21 and the power connection line 29 upward. At this time, 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 connecting battery 28. The connecting battery 28 provides alarm power to the red alarm light 30, and the connecting battery 28 emits an alarm light to remind the operator to clean the adsorption structure 7.

[0045] Please refer to the details. Figures 1-10 Each sealing mechanism includes a sealing sleeve 14, a sealing rod 15, a connecting rod 16, a sealing spring 17, and a contact block 18. The sealing sleeve 14 is fixedly connected to the upper inner wall of the adsorption treatment tank 3. The sealing rod 15 is slidably connected inside the sealing sleeve 14. The connecting rod 16 is fixedly connected to one side of the sealing sleeve 13 and the lower end of the sealing rod 15. The sealing spring 17 is fixedly connected to the upper end of the sealing rod 15 and the upper inner wall of the sealing sleeve 14. The contact block 18 is fixedly connected to one side of the connecting rod 16.

[0046] In this embodiment: the sealing spring 17 and the lifting spring 27 are both in a stretched state, and the strong elastic force of the sealing spring 17 can support the sealing sleeve 13. When the adsorption structure 7 is pulled out of the adsorption treatment tank 3, the sealing 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 multiple flow-limiting air holes 11. The sealing sleeve 13 is in contact with the outer surface of the adsorption air inlet pipe 8, and the sealing gasket 24 is provided on the lower inner wall of the sealing sleeve 13 for sealing. The flow-limiting and pressure-boosting pipe 12 supports the slide within the support 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 flow in the adsorption inlet pipe 8. When the adsorption structure 7 is being cleaned, all the air flows into the adsorption treatment groove 3 on the other side for adsorption. After cleaning, the adsorption structure 7 is reinserted into the adsorption treatment groove 3. The adsorption structure 7 contacts the contact block 18 and the weight of the adsorption structure 7 itself presses down the connecting rod 16. After the sealing sleeve 13 slides down, the lower opening of the flow-limiting air hole 11 is reopened. Air flows into the detection mechanism from the flow-limiting air hole 11 and the air inlet side hole 19 and is re-ventilated and filtered.

[0047] Please refer to the details. Figures 1-10 The lower end of the adsorption sealing plate 6 is fixedly connected to a pressure block 38, and the lower end of the pressure block 38 is in contact with the contact block 18.

[0048] In this embodiment: the pressing block 38 provided at the lower end of the adsorption sealing plate 6 presses down the contact block 18 when the adsorption structure 7 is inserted into the adsorption treatment tank 3, thereby realizing the automatic sealing and opening function of the adsorption inlet pipe 8 when the adsorption structure 7 is inserted into or pulled out of the adsorption treatment tank 3.

[0049] Please refer to the details. Figures 1-10 Limiting support blocks 32 are fixedly connected to the lower inner walls of both adsorption treatment tanks 3.

[0050] In this embodiment, the adsorption structure 7 is positioned and supported by the limiting support block 32 to ensure that the adsorption structure 7 can be accurately positioned when inserted into the adsorption treatment tank 3, and to avoid positional displacement caused by gravity or airflow impact.

[0051] Please refer to the details. Figures 1-10 The inlet end of the first vent pipe 4 is fixedly connected to a surface cooler 33, and the surface cooler 33 is equipped with a cooling pipe 34.

[0052] In this embodiment: cold water flows through the cooling pipe 34 and then through the inner cavity of the surface cooler 33, where the two exchange heat indirectly, reducing the temperature and humidity of the pollutant gas to a level suitable for adsorption by the activated carbon fiber. The flow of cold water carries away the heat.

[0053] Please refer to the details. Figures 1-10A filter 35 is fixedly connected to one end of the cooling pipe 34, and a paper core filter unit is provided inside the filter 35.

[0054] In this embodiment, the filter unit mainly consists of a paper core support and a paper core. The paper core support mainly provides structural support for the paper core. The paper core is formed by folding filter paper and fixed to the paper core support by glue. The contaminated air enters from the air inlet of the filter 35, diffuses to the surface of the paper core, and passes through the paper core under the action of airflow pressure. Large particles such as aerosols are filtered out because they cannot pass through the paper core.

[0055] Please refer to the details. Figures 1-10 A heat exchanger 36 is fixedly connected to the output end of the second vent pipe 5, and a vacuum pump 37 is fixedly connected to one side of the heat exchanger 36.

[0056] In this embodiment: the vacuum pump 37 is installed on one side of the heat exchanger 36 to enhance the air circulation efficiency of the system by generating a negative pressure environment, which helps to remove pollutants on the adsorption material more effectively and collect or discharge these pollutants. The heat exchanger 36 regulates the outlet air temperature.

[0057] Please refer to the details. Figures 1-10 The adsorption structure 7 is a drawer-type structure made of activated carbon fiber material.

[0058] In this embodiment: special activated carbon fiber fabric is stacked into an adsorption layer of a certain thickness through a dense layering method; the enclosure shell adopts an aluminum alloy plate with a high-temperature resistant insulating material lining, and the insulating material is wrapped between the ACF adsorption layer and the metal shell; the temperature measuring structure is embedded inside the ACF adsorption layer; a pair of heating electrodes are provided on the opposite side of the adsorption layer that is not ventilated, and the heating electrodes are located between the insulating material and the ACF adsorption layer.

[0059] The working principle and usage process of this invention: The device uses filter 35 as the input end and vacuum pump 37 as the output end. Temperature and humidity adjustment are completed in the surface cooler 33, and adsorption and purification are completed in the adsorption cylinder 2. The vacuum pump 37 provides air circulation power, and temperature and humidity adjustment, adsorption and purification, and desorption and regeneration are completed in the filter 35, surface cooler 33, adsorption cylinder 2, and heat exchanger 36. When the filter holes in the adsorption structure 7 become blocked to a certain extent after a long period of filtration, it affects the airflow speed on the left and right sides of the adsorption structure 7, thereby reducing the air pressure on the upper end of the lifting pipe 21, and thus the lifting... The pipe 21 is pulled upward by the lifting spring 27 and slides upward to block the through hole of the air outlet 23. During the lifting process of the lifting pipe 21, the power connection line 29 is electrically connected to the red alarm light 30, triggering the red alarm light 30 to sound an alarm. The operator pulls the adsorption structure 7 out of the adsorption treatment tank 3 for cleaning. The sealing mechanism seals the adsorption inlet pipe 8 at the same time as the adsorption structure 7 is pulled out of the adsorption treatment tank 3. The ventilation mechanism performs ventilation and filtration through another set of adsorption treatment tanks 3. After the adsorption structure 7 is cleaned, it is reinserted into the adsorption treatment tank 3 and the adsorption inlet pipe 8 is opened for ventilation.

[0060] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
