Activated carbon has a wide range of applications in the adsorption field due to its rich pore structure and large specific surface area, such as sewage treatment, air purification, etc. However, activated carbon will gradually become saturated and lose its adsorption capacity during use, so it is necessary to restore its adsorption performance through regeneration technology to achieve sustainable use.

[0007] As a further preferred embodiment of the present invention, the rotating mechanism includes an annular plate, a rotating plate and a fixed frame, the annular plate is arranged on the outside of the negative pressure ring cylinder, the rotating plate is rotatably arranged on the outside of the annular plate, and multiple groups of the fixed frames are arranged on the side of the rotating plate away from the annular plate; the air receiving mechanism includes a telescopic tube, a limit plate, an access spring, a purification tube, a sliding frame, a purification tube, an electric valve, an access tube, a groove, a proximity switch, a sensor block and a timer, the telescopic tube is connected and arranged on one side of the exhaust gas channel, the purification tube is connected and arranged on the side of the telescopic tube away from the exhaust gas channel, the limit plate is arranged at one end of the purification tube close to the telescopic tube, the access spring is arranged between the exhaust gas channel outside the telescopic tube and the limit plate, and the sliding frame is arranged at Between the exhaust gas channel and the purification pipe, the sliding frame is slidably arranged on the side wall of the exhaust gas channel, the purification cylinder is arranged on one end of the fixed frame away from the rotating plate, the electric valve is symmetrically arranged on both sides of the purification cylinder, the electric valve is connected to the purification cylinder, the access cylinder is connected on the side of the electric valve away from the purification cylinder, the groove is arranged on the side of the access cylinder away from the electric valve, and the groove is open at one end; the filtering mechanism includes a filter cylinder and a filter port, the filter cylinder is arranged on the inner wall of the purification cylinder, and multiple groups of the filter ports are arranged on the side wall of the filter cylinder, the proximity switch is symmetrically arranged on the upper walls of the two ends of the negative pressure ring cylinder, the induction block is symmetrically arranged on the side of the purification cylinder close to the proximity switch, the proximity switch and the induction block are coaxially arranged, and the timer is arranged on the upper wall of the sliding frame.

[0008] When in use, put the gas-phase adsorption activated carbon into the filter cartridge. The length of the filter cartridge is shorter than that of the purification cartridge. In the initial state, the proximity switch and the sensing block are arranged opposite to each other. The proximity switch senses the sensing block, the electric valve is in the on state, and the access spring is shortened. The access spring is shortened and drives the end of the purification tube away from the exhaust gas channel to be inserted into the groove through the limit plate. The purification tube is connected with the electric valve through the groove, and the external exhaust pipe is connected with the end of the exhaust gas channel away from the purification pipe. The exhaust gas enters the exhaust gas channel through the external exhaust pipe, and the exhaust gas inside the exhaust gas channel enters the purification pipe through the telescopic pipe. The exhaust gas inside the purification pipe enters the purification cartridge through the access cartridge and the electric valve. The exhaust gas entering the purification cartridge is discharged after being adsorbed by the gas-phase adsorption activated carbon inside the filter cartridge, and the purified gas is discharged through the electric valve on the side of the purification cartridge away from the purification pipe. The timer times the adsorption operation time of the gas-phase adsorption activated carbon inside the filter cartridge to ensure the gas-phase adsorption activity The carbon is in a period of high efficiency purification of exhaust gas. When the gas phase adsorption activated carbon operation time inside the purification tube reaches the time specified by the operator, the timer sounds, the external exhaust pipe stops transporting exhaust gas to the exhaust channel, and the purification tube is pulled. The purification tube slides along the side wall of the exhaust channel through the sliding frame by utilizing the deformation of the access spring, and the purification tube moves away from the inside of the groove. The rotating plate is rotated, and the rotating plate rotates along the annular plate through the fixed frame to drive the purification tube after operation to deviate from the purification tube. The purification tube drives the sensing block away from the proximity switch, and the proximity switch cannot sense the sensing block. The electric valves on both sides of the deviated purification tube are closed, and a new set of purification tubes reaches a position coaxial with the purification tube, and the purification tube is released. The purification tube is inserted into the groove again by utilizing the rebound of the access spring, and the proximity switch senses the sensing block. The electric valves on both sides of the new set of purification tubes are turned on, and the exhaust gas continues to be transported to the inside of the exhaust channel through the external exhaust pipe. The exhaust gas inside the exhaust channel flows into the purification tube through the purification tube for purification.

[0009] Preferably, the negative pressure mechanism includes a negative pressure air pump, a conical adsorption channel and a pressure sensor. The negative pressure air pump is arranged on the side wall of the negative pressure ring cylinder, and the suction end of the negative pressure air pump is arranged through the inside of the negative pressure ring cylinder. Multiple groups of conical adsorption channels are respectively arranged on the inner wall of the negative pressure ring cylinder, the annular plate, the rotating plate, the fixed frame and the purification cylinder. The pressure sensor is arranged on the side wall of the negative pressure ring cylinder, and the detection end of the pressure sensor is arranged through the inner wall of the negative pressure ring cylinder; the hole adjustment mechanism includes a closing spring, a closing magnetic ball and an annular electromagnet. The closing spring is arranged in the conical adsorption channel. The side wall of the purification cylinder of the part, the closed magnetic ball is arranged on the side of the closing spring close to the negative pressure ring cylinder, the annular electromagnet is arranged on the side wall of the negative pressure ring cylinder outside the conical adsorption channel, and the diameter of the conical adsorption channel increases from the negative pressure ring cylinder to the purification cylinder; the nitrogen charging mechanism includes a nitrogen charging valve, a nitrogen cylinder, a heating coil and a metal rod, the nitrogen charging valve is symmetrically arranged on the side walls of the purification cylinder on both sides of the filter cylinder, the nitrogen cylinder communication is arranged on the side of the nitrogen charging valve away from the purification cylinder, the annular plate is arranged on the inner wall of the nitrogen cylinder, and the heating coil is arranged on the inner wall of the nitrogen cylinder outside the metal rod.

[0010] When in use, in the initial state, the closing spring is in a shortened state, the closing magnetic ball is located at one end of the conical adsorption channel close to the purification cylinder, the side wall of the closed magnetic ball fits with the inner wall of the conical adsorption channel, and the conical adsorption channel is in a blocked and cut-off state. The gas phase adsorption activated carbon after adsorbing the exhaust gas is regenerated, and the negative pressure air pump discharges the gas inside the negative pressure ring cylinder through the suction end. At this time, the inside of the negative pressure ring cylinder is in a negative pressure state, and the pressure sensor detects the gas pressure inside the negative pressure ring cylinder in real time, so that the pressure inside the negative pressure ring cylinder is always in the negative pressure environment required by the operator. The rotating plate drives the fixing frame to rotate in a clockwise direction, and the fixing frame, the annular plate and the inside of the negative pressure ring cylinder are rotated. The conical adsorption channel set on the wall is misaligned, and the conical adsorption channel is blocked and cut off by the annular plate and the rotating plate. The fixed frame drives the conical adsorption channel set on the inner wall of the rotating plate to rotate and overlap with the conical adsorption channel set on the inner wall of the annular plate. The annular electromagnet is energized to generate magnetism. The annular electromagnet and the closed magnetic ball are set with opposite poles. The annular electromagnet is fixed on the side wall of the negative pressure ring cylinder and absorbs the closed magnetic ball by magnetic force. The closed magnetic ball is deformed away from the purification cylinder by the closing spring, and a gap is generated between the closed magnetic ball and the inner wall of the conical adsorption channel. The gas inside the purification cylinder flows into the inside of the negative pressure ring cylinder through the gap between the closed magnetic ball and the conical adsorption channel. The inside of the purification cylinder is changed to a negative pressure state. To avoid gas phase The adsorbed activated carbon breaks or deforms during the process of reduced pressure regeneration. The distance between the closed magnetic ball and the annular electromagnet is long, and the distance between the closed magnetic ball and the conical adsorption channel is short. The conical adsorption channel has a small adsorption area for the negative pressure inside the purification cylinder. The negative pressure acts on a smaller area, which will not produce a strong suction effect, and can reduce the probability of gas phase adsorption activated carbon breaking or deforming. When the timer rings, a new set of purification cylinders needs to be replaced and connected to the purification pipe to process the exhaust gas. The fixed frame drives the purification cylinder to continue to rotate clockwise. The annular electromagnet arranged in a circle on the side wall of the negative pressure ring cylinder gradually increases its magnetic force in the clockwise direction. When the closed magnetic ball rotates to face a new group of annular electromagnets, due to the enhanced magnetic force of the new group of annular electromagnets, the deformation degree of the closing spring becomes larger, the distance between the annular electromagnet and the closed magnetic ball is shortened, the distance between the closed magnetic ball and the conical adsorption channel is increased, and the adsorption area of ​​the conical adsorption channel on the purification cylinder is increased, so that the suction effect of the negative pressure on the gas-phase adsorption activated carbon inside the purification cylinder is enhanced. Therefore, under the same negative pressure intensity, by controlling the adsorption area, the gas-phase adsorption activated carbon inside the purification cylinder can be gradually decompressed, so as to achieve the regeneration operation of the gas-phase adsorption activated carbon without breakage or deformation.

[0011] The beneficial effects achieved by adopting the above structure are as follows:

[0012] Compared with the prior art, this solution adopts a combination of a ring-rotating structure and a distance-adjusting structure. Through the ring-type adsorption mechanism and the suction surface-type force control mechanism, the gas-phase adsorption activated carbon after the adsorption operation can be gradually decompressed under the coordinated use of the rotating mechanism, the air receiving mechanism, the filtering mechanism, the negative pressure mechanism, the hole-adjusting mechanism and the nitrogen-filling mechanism. Through the multiple groups of purification cylinders, it can ensure that the gas-phase adsorption activated carbon will not break or deform under the negative pressure environment, and the gas-phase adsorption activated carbon can be regenerated under reduced pressure without affecting the continuous adsorption and filtration operation of the gas-phase adsorption activated carbon on the exhaust gas. The negative pressure ring cylinder uses the closed spring deformation to Away from the purification cylinder, a gap is generated between the closed magnetic ball and the inner wall of the conical adsorption channel. The gas inside the purification cylinder flows into the negative pressure ring cylinder through the gap between the closed magnetic ball and the conical adsorption channel. The interior of the purification cylinder changes to a negative pressure state. To avoid the gas-phase adsorption activated carbon from breaking or deforming during the reduced pressure regeneration process, the distance between the closed magnetic ball and the annular electromagnet is longer, and the distance between the closed magnetic ball and the conical adsorption channel is shorter. The conical adsorption channel has a smaller adsorption area for the negative pressure generated inside the purification cylinder, and the negative pressure acts on a smaller area, which will not produce a strong suction effect, thereby reducing the probability of breakage or deformation of the gas-phase adsorption activated carbon.

[0030] The negative pressure mechanism 27 includes a negative pressure air pump 28, a conical adsorption channel 29 and a pressure sensor 37. The negative pressure air pump 28 is arranged on the side wall of the negative pressure ring tube 2, and the suction end of the negative pressure air pump 28 is arranged inside the negative pressure ring tube 2. Multiple groups of conical adsorption channels 29 are respectively arranged on the inner walls of the negative pressure ring tube 2, the annular plate 5, the rotating plate 6, the fixed frame 7 and the purification cylinder 14.

[0031] When in use, the gas phase adsorption activated carbon is placed inside the filter cartridge 19. The length of the filter cartridge 19 is shorter than that of the purification cartridge 14. In the initial state, the proximity switch 34 and the sensing block 35 are arranged opposite to each other. The proximity switch 34 senses the sensing block 35, the electric valve 15 is in the on state, and the access spring 11 is shortened. The access spring 11 is shortened and drives the end of the purification pipe 12 away from the exhaust gas channel 1 to be inserted into the groove 17 through the limit plate 10. The purification pipe 12 is connected to the electric valve 15 through the groove 17, and the external exhaust pipe is connected to the end of the exhaust gas channel 1 away from the purification pipe 12;

[0032] The exhaust gas enters the exhaust channel 1 through the external exhaust pipe, and the exhaust gas in the exhaust channel 1 enters the purification tube 12 through the telescopic tube 9. The exhaust gas in the purification tube 12 enters the purification tube 14 through the access tube 16 and the electric valve 15. The exhaust gas entering the purification tube 14 is discharged after being adsorbed by the gas-phase adsorption activated carbon in the filter tube 19. The purified gas is discharged through the electric valve 15 on the side of the purification tube 14 away from the purification tube 12. The timer 36 counts the adsorption operation time of the gas-phase adsorption activated carbon in the filter tube 19 to ensure that the gas-phase adsorption activated carbon is in the efficient purification period of the exhaust gas.

[0033] When the gas phase adsorption activated carbon operation time inside the purification tube 14 reaches the time specified by the operator, the timer 36 sounds, the external exhaust pipe stops conveying exhaust gas into the exhaust channel 1, and the purification tube 12 is pulled. The purification tube 12 uses the deformation of the access spring 11 to slide along the side wall of the exhaust channel 1 through the sliding frame 13. The purification tube 12 moves away from the inside of the groove 17, and the rotating plate 6 is rotated. The rotating plate 6 rotates along the annular plate 5 through the fixed frame 7 to drive the purification tube 14 after operation to deviate from the purification tube 12.

The purification pipe 12 is inserted into the groove 17 again by the rebound of the access spring 11, and the proximity switch 34 senses the induction block 35. The electric valves 15 on both sides of the new set of purification cylinders 14 are turned on, and the exhaust gas continues to be transported to the exhaust channel 1 through the external exhaust pipe. The exhaust gas in the exhaust channel 1 flows into the purification cylinder 14 through the purification pipe 12 for purification.

[0034] In the initial state, the closing spring 31 is in a shortened state, the closing magnetic ball 32 is located at one end of the conical adsorption channel 29 close to the purification cylinder 14, the side wall of the closing magnetic ball 32 is in contact with the inner wall of the conical adsorption channel 29, and the conical adsorption channel 29 is in a blocked and cut-off state. The gas phase adsorption activated carbon after adsorbing the exhaust gas is regenerated, and the negative pressure air pump 28 discharges the gas inside the negative pressure ring cylinder 2 through the suction end. At this time, the inside of the negative pressure ring cylinder 2 is in a negative pressure state, and the detection threshold of the pressure sensor 37 is pre-set. The pressure sensor 3 7 performs real-time detection of the gas pressure inside the negative pressure ring cylinder 2, so that the pressure inside the negative pressure ring cylinder 2 is always in the negative pressure environment required by the operator, the rotating plate 6 drives the fixed frame 7 to rotate in the clockwise direction, the fixed frame 7 is misaligned with the annular plate 5 and the conical adsorption channel 29 provided on the inner wall of the negative pressure ring cylinder 2, the conical adsorption channel 29 is blocked and cut off by the annular plate 5 and the rotating plate 6, the fixed frame 7 drives the conical adsorption channel 29 provided on the inner wall of the rotating plate 6 to rotate and overlap with the conical adsorption channel 29 provided on the inner wall of the annular plate 5;

[0035] The annular electromagnet 33 generates magnetism when it is energized. The annular electromagnet 33 and the closed magnetic ball 32 are arranged with opposite poles. The annular electromagnet 33 is fixed to the side wall of the negative pressure ring cylinder 2 and the closed magnetic ball 32 is adsorbed by magnetic force. The closed magnetic ball 32 is deformed away from the purification cylinder 14 by the closing spring 31. A gap is generated between the closed magnetic ball 32 and the inner wall of the conical adsorption channel 29. The gas inside the purification cylinder 14 flows into the negative pressure ring cylinder 2 through the gap between the closed magnetic ball 32 and the conical adsorption channel 29. The inside of the purification cylinder 14 changes to a negative pressure state. In order to avoid the phenomenon of fracture or deformation of the gas phase adsorbed activated carbon during the process of reduced pressure regeneration, the closed magnetic ball 32 and the annular The distance between the electromagnets 33 is relatively long, and the distance between the closed magnetic ball 32 and the conical adsorption channel 29 is relatively short. The adsorption area of ​​the negative pressure generated by the conical adsorption channel 29 on the inside of the purification cylinder 14 is relatively small. The negative pressure acts on a relatively small area, so that a strong suction effect will not be generated, which can reduce the probability of fracture or deformation of the gas phase adsorption activated carbon. When the timer 36 sounds, a new set of purification cylinders 14 needs to be replaced to connect with the purification pipe 12 to process the exhaust gas. The fixing frame 7 drives the purification cylinder 14 to continue to rotate clockwise. The annular electromagnet 33 arranged in a circle on the side wall of the negative pressure ring cylinder 2 gradually increases its magnetic force in the clockwise direction.

[0036] When the closed magnetic ball 32 rotates to face the new group of annular electromagnets 33, the magnetic force of the new group of annular electromagnets 33 is enhanced, the deformation degree of the closing spring 31 is increased, the distance between the annular electromagnets 33 and the closed magnetic ball 32 is shortened, and the distance between the closed magnetic ball 32 and the conical adsorption channel 29 is increased. The adsorption area of ​​the conical adsorption channel 29 on the purification cylinder 14 is increased, so that the suction effect of the negative pressure on the gas-phase adsorption activated carbon inside the purification cylinder 14 is enhanced. Therefore, under the same negative pressure intensity, by controlling the adsorption area, the gas-phase adsorption activated carbon inside the purification cylinder 14 can be gradually decompressed, so that the gas-phase adsorption activated carbon can be regenerated without breaking or deforming.

[0037] Control the opening of the nitrogen filling valve 22, and the heating coil 24 heats the metal rod 25. The heated nitrogen inside the nitrogen cylinder 23 flows into the purification cylinder 14 under the action of the negative pressure suction of the negative pressure ring cylinder 2, increasing the gas flow rate inside the purification cylinder 14, increasing the volatilization rate of pollutants in the gas-phase adsorption activated carbon, and evaporating the water diluted on the surface of the gas-phase adsorption activated carbon; repeat the above operation when using it next time.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
