Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas treatment for hydrogen internal combustion engines, and in particular to a post-treatment device for hydrogen internal combustion engines. Background Art

[0002] A hydrogen internal combustion engine is a traditional piston internal combustion engine that uses hydrogen as fuel. Its working principle is similar to that of a gasoline or diesel engine, but it generates power by burning hydrogen. The exhaust after-treatment system of a hydrogen internal combustion engine (HICE) is a key link in achieving near-zero emissions. Although hydrogen combustion does not produce CO2 and carbon-based pollutants (such as HC, CO, and PM), it still needs to address nitrogen oxides (NO x ) and trace amounts of other pollutants.

[0003] The document with the prior art publication number CN119508034A provides a post-treatment device for a hydrogen internal combustion engine. The side-entry centrifugal water vapor separation device facilitates the layout of the entire vehicle, can form a vortex in the exhaust gas, and the water vapor is thrown to the inner wall of the cylinder after centrifugal action, where it is cooled to form liquid water and then discharged; the water vapor that has not yet formed liquid water after the action of centrifugal force is further settled after passing through a stainless steel winding mesh assembly (the stainless steel winding mesh has a large specific surface area); after passing through the water vapor separation device, the water vapor content flowing through the H2-SCR catalytic unit can be significantly reduced, the risk of hydrothermal aging is reduced, the catalyst activity is guaranteed, and the hydrogen internal combustion engine can meet near-zero emissions for a long time.

[0004] When in use, the existing technology usually utilizes a particulate filter to filter out carbon deposited particulate matter in the exhaust gas discharged by the hydrogen internal combustion engine. However, since the existing technology lacks cleaning treatment for the particulate filter, as the use time increases, the particulate matter will continue to accumulate on the surface and pores of the filter, which will cause the air permeability of the filter to decrease, thereby affecting the flow and emission efficiency of the exhaust gas. In the absence of a cleaning mechanism, the blockage of the filter will affect its filtering effect and may even cause back pressure in the exhaust system, affecting the performance and efficiency of the hydrogen internal combustion engine.

[0005] In summary, the prior art lacks a technology for using reverse air blowing to clean the particulate matter filter in a hydrogen internal combustion engine exhaust treatment device. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By installing a jet rack in the exhaust pipe of a hydrogen internal combustion engine, after the particulate filter is turned by the adjustment seat, high-pressure gas generated by the air pump is ejected through the jet rack to perform reverse blowing and cleaning on the particulate filter. The reverse blowing can remove particulate matter accumulated on the surface and pores of the particulate filter, thereby restoring the air permeability of the particulate filter and maintaining its efficient filtering function. The high-pressure gas can effectively impact and disperse stubborn particulate matter attached to the particulate filter, avoiding the problem of clogging caused by long-term accumulation of particulate matter. This can not only improve the efficiency of the particulate filter and extend its service life, but also enhance the overall performance of the hydrogen internal combustion engine and reduce pollutant emissions.

[0018] 2. By setting up an air guide drive mechanism, the high-pressure gas generated by the air pump can be used to drive the impeller to rotate, which in turn drives the jet frame to rotate, so that the airflow can be more evenly distributed to various areas of the filter, thereby improving the overall cleaning efficiency. At the same time, the pushing mechanism can push the jet frame closer to the particulate filter when the particulate filter is turned for cleaning, providing more efficient reverse blowing, ensuring that the particulate matter on the filter surface can be completely blown away. Through the automated cleaning process, manual intervention is reduced, the cleaning effect and service life of the particulate filter are improved, and ultimately ensure the long-term efficient operation of the hydrogen internal combustion engine and meet environmental emission standards;

[0019] 3. By setting up a collision mechanism, while the jet rack is rotating for cleaning, the collision mechanism can be driven by the outer driving gear ring, so that the movable head connected by the spring continuously hits the outside of the particulate filter. The vibration generated by the collision can effectively loosen the stubborn particles on the surface and inside of the filter. The transmission of vibration helps the particles fall off, making the filter easier to clean, thereby making the jet rack cleaning effect more significant and improving the cleaning speed.

DETAILED DESCRIPTION

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0030] like Figures 1-8 The after-treatment device for a hydrogen internal combustion engine shown in the figure includes a hydrogen internal combustion engine exhaust pipe 1, an adjustment seat 2 is rotatably connected to the exhaust pipe 1, a particulate filter 3 is fixedly installed in the adjustment seat 2, a collision mechanism 4 is rotatably connected to the inner wall of the hydrogen internal combustion engine exhaust pipe 1, an air guide plate 5 is fixedly connected to the exhaust pipe 1, an injection frame 6 is rotatably connected to the air guide plate 5, a pushing mechanism 7 is rotatably connected to the air guide plate 5, an air pump 8 is fixedly connected to the outer wall of the hydrogen internal combustion engine exhaust pipe 1, and an air guide drive mechanism 9 is fixedly connected to the output end of the air pump 8.

[0031] like Figure 3 As shown, a rotating shaft 201 is fixedly connected to the upper end of the adjusting seat 2, and the top end of the rotating shaft 201 passes through the inner wall of the hydrogen internal combustion engine exhaust pipe 1 and extends to the outside and is fixedly connected to a motor 202. The motor 202 is fixedly connected to the outer wall of the hydrogen internal combustion engine exhaust pipe 1, and an annular rack 203 is fixedly connected to the inner wall of the upper end of the adjusting seat 2.

[0032] like Figure 4As shown, the collision mechanism 4 includes an L-shaped rod 401, which is rotatably connected to the inner wall of the hydrogen internal combustion engine exhaust pipe 1. A gear 402 is fixedly connected to one end of the L-shaped rod 401, and a movable head 403 is movably connected to the other end of the L-shaped rod 401. The inner wall of the movable head 403 is slidably engaged with the inner wall of the hydrogen internal combustion engine exhaust pipe 1. A spring 404 is fixedly connected between the inner wall of the movable head 403 and the inner wall of the hydrogen internal combustion engine exhaust pipe 1. The top end of the movable head 403 is movably connected to the particulate filter 3. The driving gear ring 601 drives the L-shaped rod 401 connected to the gear 402 to rotate, and then one end of the L-shaped rod 401 contacts and presses the movable head 403, causing the spring 404 connected to the movable head 403 to compress. Then, when the L-shaped rod 401 is released from contact with the movable head 403, the spring 404 acts to quickly drive the movable head 403 to return and impact the outer wall of the particulate filter 3.

[0033] like Figure 5 As shown, the air guide plate 5 has an inclined surface at one end, and a transmission wheel A501 is rotatably connected to the inner wall of the air guide plate 5, and a transmission wheel B502 is fixedly connected to the lower side of the transmission wheel A501. The inclined surface at one end of the air guide plate 5 can reduce the resistance of exhaust gas discharge.

[0034] like Figure 6 As shown, a drive ring gear 601 is fixedly connected to the jet frame 6 and meshes with the gear 402 for transmission. A movable tube 602 is fixedly connected to one end of the jet frame 6. The movable tube 602 is slidably engaged with the inner wall of the air guide plate 5. A rotating tube 603 is slidably engaged with the inner wall of the movable tube 602. A driven wheel 604 is fixedly connected to the outer wall of one end of the rotating tube 603. The driven wheel 604 meshes with the transmission wheel B502 for transmission. A tension spring 605 is fixedly connected between the movable tube 602 and the inner wall of the rotating tube 603. The transmission wheel B502 can drive the rotating tube 603 connected to the driven wheel 604 to rotate, thereby driving the jet frame 6 connected to the movable tube 602 to rotate.

[0035] By arranging a jet rack 6 in the exhaust pipe 1 of the hydrogen internal combustion engine, after the particulate filter 3 is driven to turn by the adjustment seat 2, the high-pressure gas generated by the air pump 8 is ejected through the jet rack 6 to perform reverse blowing and cleaning on the particulate filter 3. The reverse blowing can remove the particulate matter accumulated on the surface and pores of the particulate filter 3, thereby restoring the air permeability of the particulate filter 3 and maintaining its efficient filtering function. The high-pressure gas can effectively impact and break up the stubborn particulate matter attached to the particulate filter 3, avoiding the clogging problem caused by the long-term accumulation of particulate matter. It can not only improve the efficiency of the particulate filter 3 and extend its service life, but also improve the overall performance of the hydrogen internal combustion engine and reduce pollutant emissions.

[0036] like Figure 7As shown, the pushing mechanism 7 includes a worm 701, the top end of the worm 701 passes through the air guide plate 5 and the inner wall of the hydrogen internal combustion engine exhaust pipe 1 in sequence and extends to the outside, the top end of the worm 701 is fixedly connected with a universal joint 702, the other end of the universal joint 702 passes through the outer wall of the hydrogen internal combustion engine exhaust pipe 1 and extends to the inside and is fixedly connected with an adjusting wheel 703, and the adjusting wheel 703 is meshed with the annular rack 203 for transmission.

[0037] A worm gear 704 is meshed and driven at one end of the worm gear 701. A push rod 705 is fixedly connected to the worm gear 704. One end of the push rod 705 is rotatably connected to the inner wall of the air guide plate 5. The other end of the push rod 705 is rotatably connected to a contact wheel 706. The contact wheel 706 is in sliding contact with the injection frame 6. When the adjustment base 2 rotates, it drives the adjustment wheel 703 to rotate via the connected annular rack 203, causing the adjustment wheel 703 to rotate, causing the adjustment wheel 703 to rotate the worm gear 701 connected to the universal joint 702. At this time, the worm gear 701 drives the push rod 705 connected to the worm gear 704 to rotate.

[0038] like Figure 8 As shown, the air guide drive mechanism 9 includes an air guide seat 901, which is fixedly connected to the outer wall of the hydrogen internal combustion engine exhaust pipe 1, and an air intake pipe 902 is fixedly connected to the top of the air guide seat 901. The air intake pipe 902 is fixedly connected to the output end of the air pump 8, and an air guide pipe 903 is fixedly connected to the bottom end of the air guide seat 901. One end of the air guide pipe 903 extends into the air guide plate 5, and one end of the air guide pipe 903 located in the air guide plate 5 is rotatably connected to one end of the rotating tube 603.

[0039] A transmission rod 904 is rotatably connected to the inner wall of the air guide tube 903. The top of the transmission rod 904 extends into the air guide seat 901 and is fixedly connected to an impeller 905. The bottom of the transmission rod 904 is fixedly connected to a driving wheel 906, which meshes with the transmission wheel A501. When high-pressure gas passes through the air guide seat 901, it drives the impeller 905 to rotate. At this time, the impeller 905 drives the driving wheel 906 connected to the transmission rod 904 to rotate, and the driving wheel 906 then drives the transmission wheel A501 to rotate.

[0040] Working principle: The exhaust gas generated during the use of the hydrogen internal combustion engine will be processed and discharged through the particulate filter 3. When the particulate filter 3 needs to be cleaned, the motor 202 is first used to drive the connected adjustment base 2 to rotate 180 degrees, thereby swapping the positions of the air intake end and the exhaust end of the particulate filter 3.

[0041] At the same time, when the adjustment seat 2 rotates, the connected annular rack 203 drives the adjustment wheel 703 to rotate, so that the adjustment wheel 703 drives the worm 701 connected to the universal joint 702 to rotate. At this time, the worm 701 drives the push rod 705 connected to the worm gear 704 to rotate, and then the contact wheel 706 on the push rod 705 contacts and pushes the injection frame 6 close to the particulate filter 3;

[0042] Then, the air pump 8 is used to push the high-pressure gas into the air guide seat 901 through the air inlet pipe 902. The high-pressure gas is then injected into the rotating tube 603 through the air guide pipe 903 on the air guide seat 901, and then injected into the movable tube 602 through the rotating tube 603. The gas is then ejected through the injection frame 6 to perform reverse blowing and cleaning on the particulate filter 3.

[0043] At the same time, when the high-pressure gas passes through the air guide seat 901, it drives the impeller 905 to rotate. At this time, the impeller 905 drives the driving wheel 906 connected to the transmission rod 904 to rotate, so that the driving wheel 906 can drive the transmission wheel A501 to rotate. Then, the transmission wheel A501 drives the transmission wheel B502 to rotate, so that the transmission wheel B502 can drive the rotating tube 603 connected to the driven wheel 604 to rotate, thereby driving the injection frame 6 connected to the movable tube 602 to rotate, so that the injection frame 6 can fully perform air blowing and cleaning.

[0044] At the same time, when the jet frame 6 rotates, the L-shaped rod 401 connected to the gear 402 will be driven to rotate through the connected driving gear ring 601, and then one end of the L-shaped rod 401 will contact and squeeze the movable head 403, so that the spring 404 connected to the movable head 403 is compressed, and then when the L-shaped rod 401 is out of contact with the movable head 403, under the action of the spring 404, the movable head 403 will be driven to quickly reset and hit the outer wall of the particulate filter 3, causing it to vibrate and improve the cleaning efficiency. After cleaning is completed, when the jet frame 6 rotates to a vertical state, it stops rotating so that it can be retracted to one side of the air guide plate 5 under the action of the tension spring 605.
