[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0020] Reference Figures 1 to 7This embodiment provides a two-dimensional composite porous material exhaust gas toluene adsorption and purification device for purifying motor vehicle exhaust gas. It includes a channel 100, which is the airflow channel 100 of the device. Its main function is to provide a flow path for motor vehicle exhaust gas and to complete the adsorption and purification of toluene in the exhaust gas within the flow path.

[0021] Specifically, the channel 100 can be installed on the exhaust pipe of a motor vehicle. The channel 100 has an inlet end 101 and an outlet end 102. The inlet end 101 is used to connect to the upstream section of the exhaust pipe of the motor vehicle to receive untreated high-temperature toluene-containing exhaust gas. The outlet end 102 is used to connect to the downstream section of the exhaust pipe of the motor vehicle to discharge the purified gas. The channel 100 also has a treatment chamber 103 between the inlet end 101 and the outlet end 102. The treatment chamber 103 is a hollow cavity structure with internal structures for adsorbing and purifying exhaust gas. In this way, after the motor vehicle exhaust gas enters from the inlet end 101, it will flow through the treatment chamber 103. After the toluene is adsorbed and separated in the treatment chamber 103, it will be discharged from the outlet end 102.

[0022] This two-dimensional composite porous material exhaust gas toluene adsorption and purification device also includes a rotating part 200, which is installed inside the treatment chamber 103. Specifically, the rotating part 200 includes a rotating frame 201 installed in the treatment chamber 103. The rotating frame 201 can rotate relative to the treatment chamber 103. The rotating frame 201 includes at least two independent adsorption zones 202, and each adsorption zone 202 is a space that can accommodate the flow of exhaust gas.

[0023] Each adsorption zone 202 is equipped with an adsorption structure 300, which is made of a two-dimensional composite porous material. The two-dimensional composite porous material has a microporous structure, which can efficiently physically adsorb and capture toluene molecules in the exhaust gas flowing through the adsorption zone 202. The adsorption zones 202 are connected by a connecting port 203. The connecting port 203 connects the adsorption zone 202 with the desorption zone, allowing the exhaust gas that has flowed through the adsorption structure 300 in the adsorption zone 202 in the adsorption state to enter the adsorption zone 202 in the desorption state from the opposite direction through the connecting port 203. The heat carried by the exhaust gas itself purges and desorbs the adsorption structure 300 in the desorption zone, causing the toluene captured on the adsorption structure 300 to be released.

[0024] In this two-dimensional composite porous material tail gas toluene adsorption and purification device, the treatment chamber 103 is also provided with a shielding part 400. The shielding part 400 is fixedly installed on the inner wall of the treatment chamber 103. The shielding part 400 is stationary relative to the treatment chamber 103. The function of the shielding part 400 is to block part of the adsorption area 202 on the rotating frame 201.

[0025] Specifically, the adsorption zone 202, which is blocked by the shielding part 400, has its end face facing the inlet end 101 blocked by the shielding part 400, so the exhaust gas cannot flow directly from the inlet end 101. At this time, the adsorption zone 202 is in a desorption state. In the desorption state, the adsorption zone 202 is connected to the adsorption zone 202 in the adsorption state through the connecting port 203. After the exhaust gas in the adsorption zone 202 in the adsorption state completes the toluene adsorption by the adsorption structure 300, a part of the purified exhaust gas will flow back into the shielded desorption zone through the connecting port 203, and purge the adsorption structure 300 inside the desorption zone from the back. The temperature of the exhaust gas causes the toluene adsorbed on the adsorption structure 300 to desorb and be released.

[0026] The adsorption zone 202, which is not blocked by the shielding part 400, has its end face facing the inlet end 101 open. The exhaust gas flows in normally from the inlet end 101, and the adsorption zone 202 is in an adsorption state, continuously adsorbing and purifying the flowing exhaust gas with toluene. Through the rotation of the rotating frame 201, each adsorption zone 202 will alternate between being shielded by the shielding part 400 and being exposed. In this way, the equipment can desorb the adsorption structure 300 while continuously treating the exhaust gas of motor vehicles.

[0027] As an optional embodiment, the rotating frame 201 includes two rotating rings 211 and a synchronizing body 212. Specifically, the two rotating rings 211 are rotatably installed inside the processing chamber 103 at positions near the inlet end 101 and near the outlet end 102, respectively, and the two rotating rings 211 can rotate around the same central axis inside the processing chamber 103.

[0028] A synchronizing element 212 is installed between two rotating rings 211, with its two ends fixedly connected to the opposite end faces of the two rotating rings 211, respectively. In this embodiment, the function of the synchronizing element 212 is to connect the two rotating rings 211 so that they can rotate synchronously. When the rotating part 200 is working, the two rotating rings 211 and the synchronizing element 212 rotate together around the central axis of the processing chamber 103, and each adsorption zone 202 revolves around the axis together, passing through the area blocked by the blocking part 400 in sequence.

[0029] As an optional embodiment, the rotating part 200 also includes an impeller 204 connected to the synchronizing body 212. The impeller 204 is fixedly installed on the synchronizing body 212. The function of the impeller 204 is to use the flow of motor vehicle exhaust gas as power to drive the rotating part 200 to rotate.

[0030] Specifically, the blades of impeller 204 face the direction of the exhaust gas flow. When the exhaust gas from the vehicle enters the treatment chamber 103 from the inlet 101, the airflow impacts the surface of the blades of impeller 204. The airflow exerts a thrust on the blades in the direction of rotation, forming a rotational torque, which is transmitted to the synchronizing body 212 through impeller 204. The synchronizing body 212 then drives the two rotating rings 211 to rotate simultaneously.

[0031] In this embodiment, the two-dimensional composite porous material tail gas toluene adsorption and purification device also includes a locking part 500. The function of the locking part 500 is to control the rotation and stop of the rotating part 200, so that the rotating part 200 can rotate when it is necessary to switch the adsorption zone 202, and can be locked when it is not necessary to switch. The locking part 500 has two working states, namely the unlocked state and the locked state. When the locking part 500 is in the unlocked state, the impeller 204 is not constrained and can rotate under the continuous impact of the tail gas flow, thereby driving the entire rotating part 200 to rotate and complete the switching action of the adsorption zone 202. When the locking part 500 is in the locked state, the rotating part 200 is locked and fixed, the impeller 204 cannot continue to rotate, and the position of each adsorption zone 202 is locked.

[0032] As an optional embodiment, the locking part 500 includes a locking ring 501, a locking tube 502, and a locking pin 503. Specifically, the locking ring 501 is fixedly installed on the synchronizing body 212 and can rotate together with the synchronizing body 212. A locking groove 511 is provided on the outer circumferential surface of the locking ring 501. The locking groove 511 is recessed inward along the radial direction of the locking ring 501. The number and position of the locking grooves 511 correspond to the number and position of the adsorption areas 202. When the rotating part 200 rotates to a position where a certain adsorption area 202 is completely blocked by the blocking part 400, a locking groove 511 on the locking ring 501 also rotates to a position directly opposite the locking pin 503.

[0033] The locking tube 502 is fixedly installed on the processing chamber 103. The position of the locking tube 502 relative to the processing chamber 103 is fixed. An axially extending sliding channel 100 is provided inside the locking tube 502. The locking pin 503 is slidably installed inside the sliding channel 100 of the locking tube 502. When the locking pin 503 slides forward relative to the locking tube 502, its end can extend into the locking groove 511 on the locking ring 501, which is directly opposite to it. The end of the locking pin 503 and the locking groove 511... The groove wall forms a snap-fit ​​engagement, thereby locking the locking ring 501 and preventing the locking ring 501 and the entire synchronizing body 212 from continuing to rotate. At this time, the locking part 500 is in a locked state, and the rotating part 200 is locked and fixed. When the locking pin 503 slides backward relative to the locking tube 502 and its end comes out of the locking groove 511, the locking ring 501 is released. At this time, the locking part 500 is in an unlocked state, and the rotating part 200 can continue to rotate under the drive of the impeller 204 to switch the adsorption zone 202.

[0034] As an optional embodiment, the locking part 500 further includes a driving member 504. The function of the driving member 504 is to provide driving force for the reciprocating sliding of the locking pin 503, so that the locking pin 503 can accurately extend into or exit the locking groove 511 according to control requirements. Specifically, the driving member 504 is fixedly installed on the locking tube 502 or on the housing of the processing chamber 103. When it is necessary to release the rotating part 200 to rotate, the driving member 504 drives the locking pin 503 to slide backward relative to the locking tube 502, and the end of the locking pin 503 disengages from the locking groove 511, locking... When ring 501 is released, rotating part 200 resumes its rotational ability. In this embodiment, driving member 504 adopts an electromagnet structure. When driving member 504 is energized, it can attract locking pin 503, causing locking pin 503 to move away from locking ring 501, thereby unlocking the entire rotating part 200. When driving member 504 is de-energized, locking pin 503 can fall back towards locking ring 501 under the action of gravity. It should be further noted that a spring can also be installed between locking pin 503 and locking tube 502 to help locking pin 503 reset.

[0035] As an optional embodiment, the axial cross-section of the synchronizing body 212 is cross-shaped. Specifically, the synchronizing body 212 extends along the axial direction of the processing chamber 103, and its cross-section perpendicular to the axial direction is cross-shaped. The center of the cross coincides with the rotation axis of the rotating frame 201. The four wing plates of the synchronizing body 212 extend radially outward, and the end of each wing plate is connected to the boundary of the adsorption zone 202. In this way, the cross-shaped synchronizing body 212 evenly divides the annular space inside the rotating frame 201 into four independent adsorption zones 202. Each adsorption zone 202 occupies a fan-shaped angle of about ninety degrees in the circumferential direction. The four adsorption zones 202 are arranged sequentially in the circumferential direction. The adjacent adsorption zones 202 are isolated by the wing plates of the synchronizing body 212, so that the airflow inside each adsorption zone 202 will not communicate with each other. When the rotating part 200 rotates, the four adsorption zones 202 rotate around the axis together with the synchronizing body 212, passing through the positions blocked by the shielding part 400 and the exposed positions in sequence.

[0036] As an optional embodiment, each shielding part 400 includes two shielding wings 401. The two shielding wings 401 are symmetrically arranged in the processing chamber 103. The function of the shielding wings 401 is to shield and seal a specific adsorption area 202 on the rotating frame 201, blocking the exhaust gas from flowing into the shielded adsorption area 202 from the direction of the inlet end 101, so that it changes to a desorption state. Specifically, the shielding wing 401 is a plate-shaped structure, and its shielding surface faces the direction of the inlet end 101. The shape and size of the shielding wing 401 match the shape of the end face of the individual adsorption area 202 facing the inlet end 101.

[0037] In this embodiment, the synchronizing body 212 divides the rotating frame 201 into four adsorption zones 202, each occupying approximately a 90-degree circumferential angle. Two shielding wings 401 also each occupy approximately a 90-degree shielding range, and the two shielding wings 401 are symmetrically distributed 180 degrees circumferentially. When the rotating part 200 rotates to a certain position, the two shielding wings 401 respectively cover the entire end face of two opposing adsorption zones 202 facing the inlet end 101, completely isolating these two adsorption zones 202 from the incoming flow from the inlet end 101. The exhaust gas cannot enter the interior of these two adsorption zones 202, and these two adsorption zones 202 are in a desorption state. The other two adsorption zones 202, not covered by the shielding wings 401, have their end faces facing the inlet end 101 open, allowing the exhaust gas to flow in normally, and are in an adsorption state. Thus, during equipment operation, there are always two adsorption zones 202 performing adsorption purification and two adsorption zones 202 performing desorption regeneration. Figure 6 As shown, two adsorption regions 202 are located in the exposed region R1, and two adsorption regions 202 are located in the shielded region R2.

[0038] For example Figure 5 As shown, solid arrows indicate the flow direction of the exhaust gas in the adsorption zone 202 when it is in the adsorption state, and dashed arrows indicate the flow direction of the exhaust gas in the adsorption zone 202 when it is in the desorption state.

[0039] As an optional embodiment, the treatment chamber 103 is provided with a blowout port 104. The blowout port 104 is located at the end of the treatment chamber 103 near the inlet end 101. The function of the blowout port 104 is to concentrate and export the toluene-containing concentrated waste gas released from the adsorption zone 202 in the desorption state to the treatment chamber 103 and send it to the vehicle engine intake system or other treatment structures for secondary combustion or purification treatment, so as to prevent the desorbed toluene from being discharged into the atmosphere from the outlet end 102 along with the airflow.

[0040] Specifically, the blow-out port 104 is located on the side wall of the processing compartment 103, close to the inlet end 101, and coincides with the position of the compartment wall corresponding to the adsorption area 202 blocked by the shielding wing 401. The connecting port 203 is located at the end of the outlet end 102. That is to say, the connecting port 203 is located on the rotating frame 201 near the outlet end 102, and each adsorption area 202 is interconnected with each other near the outlet end 102 through the connecting port 203.

[0041] In this embodiment, when an adsorption zone 202 rotates to a position blocked by the shielding wing 401 and becomes a desorption zone, the end face of the adsorption zone 202 facing the inlet end 101 is closed by the shielding wing 401, and the exhaust gas cannot flow in from the inlet end 101 in the forward direction. However, the end face of the adsorption zone 202 facing the outlet end 102 is connected to the adsorption zone 202 in the adsorption state through the connecting port 203. A portion of the exhaust gas that has completed toluene adsorption inside the adsorption zone 202 in the adsorption state will flow in reverse into the blocked desorption zone through the connecting port 203 at the end of the outlet end 102, and perform reverse purging on the adsorption structure 300 inside the desorption zone from the back. The heat carried by the exhaust gas itself is used to desorb and release the toluene captured on the adsorption structure 300.

[0042] The toluene-containing concentrated waste gas generated during desorption is extracted from the treatment chamber 103 under the guidance of the blow port 104 and sent to the intake manifold of the motor vehicle engine through the pipeline connected to the blow port 104 to participate in combustion.

[0043] As an optional embodiment, a bearing 105 is installed inside the processing chamber 103, and a rotating ring 211 is installed inside the processing chamber 103 via the bearing 105. Specifically, the outer ring of the bearing 105 is fixedly embedded in the inner wall of the processing chamber 103, and the inner ring of the bearing 105 is fixedly engaged with the outer circumferential surface of the rotating ring 211.

[0044] As an optional embodiment, there are two shielding parts 400. Both shielding parts 400 are fixedly installed on the inner wall of the treatment chamber 103, and the two shielding parts 400 respectively fit into the two axial ends of the adsorption zone 202. Specifically, the axial direction of the treatment chamber 103 is the direction in which the exhaust gas flows from the inlet end 101 to the outlet end 102. The adsorption zone 202 is axially connected on the rotating frame 201 and has a first axial end facing the inlet end 101 and a second axial end facing the outlet end 102.

[0045] Of the two shielding parts 400, one shielding part 400 is installed on the inner wall of the processing chamber 103 near the inlet end 101, adhering to the first axial end of the adsorption zone 202, and the other shielding part 400 is installed on the inner wall of the processing chamber 103 near the outlet end 102, adhering to the second axial end of the adsorption zone 202. In this way, when the rotating frame 201 rotates to a certain position, the two shielded adsorption zones 202 are respectively covered by the two shielding parts 400 at their two axial ends, and the two shielding parts 400 completely seal the shielded adsorption zones 202 from both axial ends, forming a relatively closed desorption chamber.

[0046] In this state, the first axial end of the adsorption zone 202 facing the inlet 101 is closed by the first shielding part 400, preventing the exhaust gas from flowing in the forward direction. The second axial end facing the outlet 102 is closed by the second shielding part 400, so the toluene-containing concentrated waste gas generated by desorption will not leak out from this end at will, but will be discharged through the blowing port 104. The two shielding parts 400 are simultaneously attached from both axial ends, which can isolate the adsorption zone 202 in the desorption state from the external airflow.

[0047] After the exhaust gas from the vehicle is discharged from the exhaust pipe, it enters the treatment chamber 103 through the inlet end 101 of the channel 100. After entering the treatment chamber 103, the exhaust gas first flows through two adsorption zones 202 in an adsorption state. The end faces of these two adsorption zones 202 facing the inlet end 101 are not covered by the shielding wing 401 and are in an open state, allowing the exhaust gas to flow in normally. When the exhaust gas flows through the interior of the adsorption zone 202, it comes into contact with the adsorption structure 300 made of two-dimensional composite porous material set in the adsorption zone 202. Toluene molecules in the exhaust gas are adsorbed by the adsorption structure 300. After the adsorption and purification are completed, the exhaust gas flows towards the outlet end 102.

[0048] During this process, the other two adsorption zones 202 on the rotating frame 201 are covered by two shielding wings 401, respectively, and are in a desorption state. The inlet end 101 of the desorption zone is closed by the shielding wings 401, and the exhaust gas cannot flow in the forward direction. However, the outlet end 102 of the desorption zone is connected to the outlet end 102 of the adsorption zone 202 through the connecting port 203. The clean exhaust gas that has completed the adsorption of toluene in the adsorption zone 202 will flow back into the desorption zone through the connecting port 203 when it flows through the outlet end 102. It will perform reverse purging on the adsorption structure 300 in the desorption zone from the back. The heat of the exhaust gas will raise the temperature of the adsorption structure 300. The toluene molecules previously captured on the adsorption structure 300 will gain energy and be desorbed and released from the adsorption site, forming concentrated exhaust gas containing toluene.

[0049] The concentrated exhaust gas generated by desorption is concentrated and extracted through the blow port 104 on the side of the treatment chamber 103 near the inlet end 101, and sent through the pipeline to the intake manifold of the motor vehicle engine to participate in secondary combustion, or sent to a separate after-treatment device for oxidation and decomposition.

[0050] When the desorption zone completes regeneration and the adsorption zone 202 approaches saturation, the locking part 500 switches to the unlocked state. Under the continuous impact of the exhaust gas flow, the impeller 204 drives the synchronizing body 212 and the two rotating rings 211 to rotate together. The four adsorption zones 202 rotate 90 degrees around the axis. The two adsorption zones 202 that were originally in the adsorption state rotate to the area below the shielding wing 401 and change to the desorption state to regenerate the adsorption structure 300. The two adsorption zones 202 that were originally in the desorption state and have completed regeneration rotate to the exposed position and change to the adsorption state.

[0051] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
