Description

Technical Field

[0001] This invention relates to the field of exhaust gas waste heat recovery technology, and in particular to a mechanism for recovering and recycling exhaust gas waste heat from automobiles. Background Technology

[0002] With the continued advancement of the dual-carbon strategy, methanol-fueled heavy trucks have been widely promoted and applied in the land freight sector due to their advantages of being clean, low-carbon, and having low fuel costs. However, their exhaust still emits a large amount of carbon dioxide, making it impossible to achieve carbon neutrality throughout the entire process.

[0003] Currently, the mainstream solution in the industry is to use an on-board carbon bin, which fills the carbon bin with a solid adsorbent to capture carbon dioxide in the exhaust gas. After the adsorbent is saturated, the carbon bin is removed for desorption and regeneration. The desorbed carbon dioxide is then combined with hydrogen to synthesize methanol, thus achieving carbon recycling of the exhaust gas. However, in existing fixed-bed carbon bins with whole-bin filling, the saturation of the adsorbent is severely uneven along the airflow direction when the exhaust gas is introduced into the bed from bottom to top. When the bottom layer of adsorbent is saturated, there is still a large amount of excess capacity in the upper layer, resulting in a serious underutilization of the regenerated adsorbent. In addition, the downtime for each replacement of the whole bin is long, which seriously affects the operating efficiency of trucks. At the same time, the main sealing interface between the carbon bin and the vehicle exhaust gas pipeline needs to be frequently disassembled and reassembled, which can easily cause wear and fatigue failure of the seals, leading to the risk of direct exhaust gas leakage.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1-6This is the first embodiment of the present invention. This embodiment provides a vehicle exhaust waste heat recovery and recycling mechanism. The vehicle exhaust waste heat recovery and recycling mechanism includes a carbon bin 11, which is used to store adsorbent particles. The adsorbent particles can capture carbon dioxide in the exhaust gas. The top and bottom of the carbon bin 11 are respectively provided with an air inlet pipe 12 and an air outlet pipe 13. The air inlet pipe 12 is connected to the vehicle exhaust pipe. The exhaust gas enters the interior of the carbon bin 11 through the air inlet pipe 12, and the carbon dioxide in the exhaust gas can be adsorbed by the adsorbent particles inside. The purified exhaust gas will be discharged through the air outlet pipe 13. This is the prior art, and this solution will not be described in detail.

[0034] Auxiliary component 2, located inside carbon chamber 11, includes support box 21. The support box 21 is hollow, and the gaps are slightly smaller than the diameter of the adsorbent particles. There are multiple support boxes 21, which are evenly distributed in a straight line inside carbon chamber 11. The adsorbent is placed in layers through the support boxes 21, so that the exhaust gas can pass through each support box 21 in sequence to achieve gradient uniform adsorption. Based on the layered arrangement, it can match the carbon dioxide concentration gradient in the exhaust gas, so as to achieve high-concentration pre-adsorption at the bottom layer and low-concentration fine adsorption at the top layer, which greatly improves the carbon dioxide capture efficiency and adsorbent utilization rate.

[0035] The carbon chamber 11 has channels on both the top and bottom sides. The bottom channel is used to remove the bottom support box 21, while the top channel is used to put the purified support box 21 into the carbon chamber 11. Both channels are equipped with sealing doors to block the channels and prevent exhaust gas leakage.

[0036] The auxiliary component 2 also includes a support member 22, which includes a slider 221 fixed to the side of the support box 21. There are four sliders 221 on each support box 21, located at the front and rear ends of the two sides of the support box 21 respectively. One side of the slider 221 is open. There are four support frames 222 fixed inside the carbon chamber 11, located on both sides of the two through slots above and below the carbon chamber 11 respectively. When the support box 21 is taken out and inserted, it is supported by the support frames 222.

[0037] The bottom of the support frame 222 is fixed with a slide rail 223. There are four slide rails 223, which are located on both sides of the bottom of the two support frames 222 respectively. The bottom and top of the slide rails 223 are connected to the two support frames 222 above and below respectively. There are two threaded rods 224 in the slide rails 223. They are arranged diagonally in the two diagonally opposite slide rails 223. The slider 221 has a cavity 221-1. A threaded plate 225 is provided in the cavity 221-1. The threaded plate 225 is semi-circular.

[0038] When the support box 21 is inserted into the through slot, the slider 221 will enter the support frame 222. At this time, the two work together to support the support box 21. When the support box 21 is completely inserted into the carbon bin 11, the slider 221 will align with the slide rail 223 and move downward. When the downward-moving support box 21 reaches the specified distance with the adjacent support box 21 below, the threaded plate 225 will move outward and engage with the threaded rod 224. At this time, the two work together to limit the height of the support box 21, so that the support box 21 stops moving downward. At this time, the distance between each support box 21 is consistent.

[0039] During desorption and regeneration, only the bottom saturated support box 21 needs to be removed. At this time, the threaded rod 224 will rotate and, with the cooperation of the threaded plate 225, drive the support box 21 to move downward. After the bottom support box 21 is removed, the upper support boxes 21 will move downward in sequence, and the upper layers will move down to fill the gaps. The corresponding saturated layers can be removed as needed, which can significantly reduce the amount of regeneration adsorbent, reduce desorption energy consumption and cost, and avoid wasting unsaturated adsorbent.

[0040] A support block 226 is fixed to the inner wall of the slide rail 223. There are multiple support blocks 226, which are evenly distributed in a straight line inside the slide rail 223. An annular groove is opened on the threaded rod 224. The position of the annular groove of the threaded rod 224 is rotatably connected to the support block 226 through a bearing. Since one side of the slider 221 is open, the support block 226 will not obstruct the slider 221 when it moves down.

[0041] Example 2, refer to Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0042] Specifically, the auxiliary component 2 also includes a pusher 23. The pusher 23 includes a force-receiving block 231 fixed to one side of the threaded plate 225. One side of the force-receiving block 231 is inclined. A pressing rod 232 is inserted into the slider 221. A portion of the lower part of the pressing rod 232 is located outside the slider 221, and the contact point between the pressing rod 232 and the slider 221 is made of elastic and bendable metal.

[0043] A fixing block 233 is fixed to one side of the top of the extrusion rod 232, and a spring 234 is fixed to the bottom of the fixing block 233. The bottom end of the spring 234 is fixed to the inner wall of the chamber 221-1.

[0044] When inserting the support box 21, the extrusion rod 232 is first pushed upward so that it is fully inserted into the slider 221. At this time, the slider 221 can enter the support frame 222 without any obstruction. At the same time, the spring 234 will apply a downward pulling force to the fixing block 233 and the extrusion rod 232, so that the bottom end of the extrusion rod 232 extends to the outside of the slider 221.

[0045] When the slider 221 moves downward along the slide rail 223 and the bottom end of the pressing rod 232 contacts another slider 221 below, it will be pushed upward and move upward, and apply a pushing force to the force block 231, causing the force block 231 to drive the threaded plate 225 to move, thereby allowing the threaded plate 225 to mesh with the threaded rod 224. At this time, the support box 21 will stop moving.

[0046] The lower support frame 222 has an insertion hole. After the slider 221 enters the lower support frame 222, the pressing rod 232 will be inserted into the insertion hole. When the support box 21 is removed, the pressing rod 232 will be pressed against the inner wall of the insertion hole on the support frame 222 as the support box 21 moves. At this time, the pressing rod 232 will bend and rotate to fit against the bottom of the slider 221, so as not to hinder the slider 221 from moving out of the slide rail 223.

[0047] The auxiliary component 2 also includes a rotating component 24, which includes a reel 241 rotatably connected to the outside of the threaded rod 224. The reel 241 is located outside the annular groove on the threaded rod 224. The reel 241 is rotatably connected to the outside of the annular groove through a one-way bearing. A pull rope 242 is wound around the outside of the reel 241. A coil spring 243 is fixed at the bottom of the reel 241. The bottom end of the coil spring 243 is fixed to the support block 226. A movable plate 244 is provided inside the carbon bin 11. The other end of the pull rope 242 is fixed to the movable plate 244. The movable plate 244 is L-shaped and has a friction strip on the top. The bottom support box 21 will press on the top of the movable plate 244.

[0048] When the support box 21 is pulled outward, it will drive the movable plate 244 to move under the action of friction, and the movable plate 244 will pull the pull rope 242 to move. At this time, the pull rope 242 will drive the winding wheel 241 to rotate. Under the action of the one-way bearing, the winding wheel 241 will not drive the threaded rod 224 to rotate, and will tighten and charge the coil spring 243.

[0049] When the support box 21 is removed from the carbon chamber 11 and separated from the movable plate 244, the coil spring 243 will release its elastic force and drive the coil wheel 241 to rotate in the opposite direction. At this time, the coil wheel 241 will wind up the pull rope 242 and drive the threaded rod 224 to rotate, so that the threaded rod 224 can drive the threaded plate 225 to move downward.

[0050] The pull rope 242 passes around the back of the slide rail 223, and a guide wheel is provided at the corresponding position to ensure that the pull rope 242 will not get tangled or obstruct the movement of other parts.

[0051] The movable plate 244 is equipped with a pulley 245 at its bottom, and a slide rod 246 is fixed to the inner wall of the carbon chamber 11. The pulley 245 slides on the top of the slide rod 246. The end of the slide rod 246 near the sealing door protrudes upward. The movable plate 244 is supported and positioned by the cooperation of the pulley 245 and the slide rod 246. The protruding end of the slide rod 246 is used to limit the pulley 245 and will stop moving after the movable plate 244 moves to the designated position.

[0052] A guide plate 247 is fixed to the inner wall of the carbon chamber 11. The guide plate 247 is inclined and its top is fixed to the support frame 222. The guide plate 247 is used to block the exhaust gas entering the carbon chamber 11, so that the exhaust gas can only flow to the space between the two support frames 222 and will not enter the space where the slide rail 223 is located, thus avoiding the situation where the exhaust gas cannot be purified.

[0053] Example 3, referring to Figure 3 , Figures 5-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0054] Specifically, the auxiliary component 2 also includes a flipping element 25, which includes a reciprocating roller 251 rotatably connected inside the support box 21. The groove width on the outer side of the reciprocating roller 251 is smaller than the diameter of the adsorbent particles, which can prevent the adsorbent particles from entering the groove of the reciprocating roller 251. A movable sleeve 252 is sleeved on the outer side of the reciprocating roller 251, and a fixed shaft 253 is fixed inside the movable sleeve 252. The fixed shaft 253 meshes with the reciprocating roller 251. A flipping frame 254 is provided on the outer side of the movable sleeve 252. The flipping frame 254 is rake-shaped and will be subjected to suction when moving. When the adsorbent particles experience excessive resistance, the turning frame 254 tilts. As the turning frame 254 moves, it generates a pushing force along the direction of movement and a loosening force in the vertical direction on the adsorbent particles. This allows for a combination of cutting, lifting, and dispersing actions on the particles, breaking down the compaction, bridging, and clumping of the adsorbent particles within the honeycomb pores. This keeps the particles in a loose, fluidized state, ensuring that the exhaust gas flows through evenly. It also helps to distribute the particles uniformly, making each layer of adsorbent fill with a uniform density, avoiding localized compaction or voids, and extending the adsorbent's service life.

[0055] When the flipping frame 254 moves, its bottom is tilted in the forward direction, so that the flipping frame 254 has a scooping effect on the adsorbed particles when it moves.

[0056] A gear 255 is fixed at the end of the reciprocating roller 251, and a toothed plate 256 is fixed on the inner wall of the carbon bin 11. The gear 255 and the toothed plate 256 cooperate. When the support box 21 moves downward, the gear 255 will rotate on one side of the toothed plate 256 and drive the reciprocating roller 251 to rotate through the gear 255.

[0057] A frame 257 is fixed to the outside of the movable sleeve 252, and a block 258 is fixed to the flipping frame 254. The block 258 slides inside the frame 257. The two work together to connect the flipping frame 254 to the movable sleeve 252, so that the flipping frame 254 can move with the movable sleeve 252 and can also rotate outside the movable sleeve 252. The block 258 is T-shaped, and the connection between the block 258 and the frame 257 is relatively tight and will not slide due to the obstruction of adsorbed particles. A flexible shielding piece can be added to the opening of the frame 257 to block the opening of the frame 257, so as to prevent adsorbed particles from entering the interior of the frame 257 and not to obstruct the movement of the block 258 inside the frame 257. A push rod 259 is fixed to the inner wall of the support box 21. There are two push rods 259, which are located on both sides inside the support box 21.

[0058] When the tilting frame 254 moves to the end of one side inside the support box 21, the push rod 259 will contact the tilting frame 254. As the tilting frame 254 moves, the push rod 259 will apply a pushing force to the tilting frame 254 and cause the tilting frame 254 to rotate to another angle. When the tilting frame 254 moves in the opposite direction, its bottom is always tilted in the forward direction.

[0059] A positioning block 252-1 is fixed on one side of the movable sleeve 252, and a support column 252-2 is fixed on the inner wall of the support box 21. The positioning block 252-1 is movably connected to the outer side of the support column 252-2. The two cooperate to guide and position the movable sleeve 252, so as to prevent the movable sleeve 252 from rotating when it moves.

[0060] In use, adsorbent granules are loaded into the support box 21, and the support box 21 is then inserted into the carbon chamber 11. When the support box 21 is inserted into the through groove, the slider 221 enters the support frame 222. At this time, the two work together to support the support box 21. When the support box 21 is fully inserted into the carbon chamber 11, the slider 221 aligns with the slide rail 223 and moves downward. When the moving support box 21 reaches the specified distance with the adjacent support box 21 below, the bottom end of the extrusion rod 232 contacts another adjacent slider 221 below, and is pushed upward by an upward force, thus applying a pushing force to the force block 231. This causes the force block 231 to drive the threaded plate 225 to move, thereby allowing the threaded plate 225 to mesh with the threaded rod 224. At this time, the two work together to limit the height of the support box 21, stopping the support box 21 from moving downward. At this time, the distance between each support box 21 remains consistent.

[0061] By placing the adsorbent in layers using multiple support boxes 21, the exhaust gas can pass through each support box 21 sequentially, achieving gradient uniform adsorption. Relying on the layered arrangement, it can match the carbon dioxide concentration gradient in the exhaust gas, achieving high-concentration pre-adsorption at the bottom layer and low-concentration fine adsorption at the top layer, greatly improving the carbon dioxide capture efficiency and adsorbent utilization rate.

[0062] During desorption and regeneration, only the bottom saturation support box 21 needs to be removed. When the support box 21 is pulled outward, it will cause the movable plate 244 to move under the action of friction, and the movable plate 244 will pull the pull rope 242 to move. At this time, the pull rope 242 will drive the winding wheel 241 to rotate. However, under the action of the one-way bearing, the winding wheel 241 will not drive the threaded rod 224 to rotate, and will tighten and charge the coil spring 243. When the support box 21 is removed from the carbon chamber 11 and separated from the movable plate 244, the coil spring 243 will... 43 will release elasticity and drive the reel 241 to rotate in the opposite direction. At this time, the reel 241 will wind up the pull rope 242 and drive the threaded rod 224 to rotate. With the cooperation of the threaded plate 225, the support box 21 will move downward. After the support box 21 at the bottom is removed, the support box 21 at the top will move downward in sequence. The upper layer will move down to fill the gap in sequence. The corresponding saturated layer can be taken out as needed, which can greatly reduce the amount of regenerated adsorbent, reduce desorption energy consumption and cost, and avoid the waste of unsaturated adsorbent.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
