[0029] The technical solution of the present invention will now be clearly and completely described 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.

[0030] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 This invention provides a fuel cell hydrogen recirculation system, including a chassis 1. A motor 2 is fixedly connected to the outside of the chassis 1. A condensation assembly 5 is provided at the output end of the motor 2. A condensation cylinder 6 is fixedly connected to the inside of the chassis 1. A water storage tank 7 is fixedly connected to the inside of the chassis 1. The condensation assembly 5 includes a first transmission plate 51. One end of the first transmission plate 51 is rotatably connected to the outside of one side of a transmission wheel 3. A second rotating plate 52 is rotatably connected to the outside of the other side of the first transmission plate 51. The other side of the second rotating plate 52... A rotating disk 53 is rotatably connected to the outside of the side. A toothed plate 54 is slidably connected to the upper outside of the rotating disk 53. A first gear 55 is meshed with the tooth ends of the toothed plate 54. A rotating tube 56 is fixedly connected inside the first gear 55. A heat-conducting plate 57 is fixedly connected to one end of the rotating tube 56. A condenser 58 is fixedly connected to the outside of one side of the heat-conducting plate 57. An air inlet pipe 9 is rotatably connected to the outside of the rotating tube 56. A denitrifier 18 is fixedly connected inside the casing 1. An air outlet pipe 19 is fixedly connected to the upper surface of the denitrifier 18.

[0031] Specifically, the chassis 1 provides fixed support for internal and external components, the condensation assembly 5 condenses and removes water from the hydrogen gas introduced into the condenser cylinder 6, the first transmission plate 51 drives the second rotating plate 52 to rotate, the second rotating plate 52 transmits the power of the first transmission plate 51 to the rotating disk 53, and simultaneously achieves the conversion of power direction in coordination with the movement of the rotating disk 53. The rotating disk 53 rotates under the drive of the second rotating plate 52, thereby driving the toothed plate 54 to reciprocate. The toothed plate 54 drives the first gear 55 to rotate through meshing transmission. The first gear 55 rotates synchronously under the meshing drive of the toothed plate 54, thereby driving the rotating tube 56 to rotate. One end of the rotating tube 56 is fixed to the heat-conducting plate 57, and the other end is fixed to the external air inlet pipe 9. It is used to transmit the rotational power of the first gear 55 to the heat-conducting plate 57, and also serves as a gas channel, allowing the gas in the air inlet pipe 9 to enter the flow channel on the side of the heat-conducting plate 57. The condenser 6 provides a reaction space for gas condensation and is connected to the water storage tank 7 through a pipe. The water storage tank 7 receives the liquid generated by condensation in the condenser 6 through a pipe, realizing the collection and storage of condensate. The denitrifier 18 is existing technology and is equipped with nitrogen separation components (such as molecular sieve membrane separation components). It mainly removes nitrogen components from the gas through the separation action of the denitrifier 18, realizing the function of hydrogen purification.

[0032] Please see the appendix Figure 5 The condenser cylinder 6 is equipped with a propulsion assembly 8 inside. The air inlet pipe 9 is fixedly connected to the outside of the other end of the rotating pipe 56. The heat conduction plate 57 is rotatably connected to the inside of the condenser cylinder 6. The rotating pipe 56 is rotatably connected to the inside of the casing 1. The rotating disk 53 is rotatably connected to the inside of the casing 1. The condenser cylinder 6 and the water storage tank 7 are connected by a pipe.

[0033] Specifically, the propulsion assembly 8 is used to push the gas for filtering water into the filter cartridge 15, thereby accelerating the gas flow and transport. The heat-conducting plate 57 rotates under the drive of the rotating tube 56 and transfers the cooling capacity of the condenser tube 58. At the same time, the rotation promotes the contact between the gas in the condenser cartridge 6 and the condenser tube 58. The condenser tube 58 is fixed to one side of the heat-conducting plate 57 and rotates synchronously with the heat-conducting plate 57. As the core component of condensation, it exchanges heat with the gas in the condenser cartridge 6 through its own cooling capacity to achieve the condensation of gaseous water in the gas. The inlet pipe 9 transports the gas to be treated into the rotating tube 56 and then into the condenser cartridge 6.

[0034] Please see the appendix Figure 5 The propulsion assembly 8 includes a lead screw 81, one end of which is fixedly connected to the inside of the condenser cylinder 6. A push plate 82 is threadedly connected to the outside of the lead screw 81. A fixing column 83 is fixedly connected to one side of the heat-conducting plate 57. The inside of the push plate 82 is slidably connected to the outside of the fixing column 83. An air plate 84 is fixedly connected to the outside of the push plate 82.

[0035] Specifically, the lead screw 81 provides a threaded transmission structure for the push plate 82, and its position is fixed and does not rotate. The push plate 82 has a threaded hole inside, and at the same time, it has a sliding hole inside, which can slide along the axis of the fixed column 83. However, it is constrained by the thread of the lead screw 81 and cannot rotate on its own. The fixed column 83 rotates synchronously with the heat conduction plate 57, and the gas plate 84 can reciprocate linearly with the push plate 82. During the movement, it can push the gas in the condenser 6, promote the full contact between the gas and the condenser tube 58, and accelerate the flow of gas towards the filter cartridge 15.

[0036] Please see the appendix Figure 4 and attached Figure 6 The output end of the motor 2 is connected to two transmission wheels 3. A transmission belt 4 is provided on one side of the transmission wheel 3. An outer shell 10 is fixedly connected inside the housing 1. A transmission shaft 11 is fixedly connected to the other side of the transmission wheel 3. A push column 12 is fixedly connected to one side of the transmission shaft 11. A push frame 13 is slidably connected to the outside of the push column 12. A filter assembly 14 is provided on one side of the push frame 13. A filter cylinder 15 is fixedly connected to one side of the outer shell 10.

[0037] Specifically, the output end of motor 2 is directly connected to transmission wheel 3 to provide power output to the system. There are two transmission wheels 3, which are synchronously driven by transmission belt 4. When transmission wheel 3 rotates under the drive of motor 2, it can synchronously drive transmission shaft 11 to rotate, realizing the transmission of power from transmission wheel 3 to transmission shaft 11. When transmission shaft 11 rotates, push column 12 moves eccentrically with transmission shaft 11. The push frame 13 has an elongated hole that matches push column 12. When push column 12 moves eccentrically, it slides in the elongated hole, and at the same time drives push frame 13 to move reciprocating linearly in a direction perpendicular to the axis of transmission shaft 11. Filter assembly 14 is used for secondary adsorption to remove moisture from gas. Filter cylinder 15 forms a filter chamber to accommodate filter assembly 14 and provide space for the filtration of moisture in hydrogen-containing gas. Filter cylinder 15 is connected to subsequent metering cylinder 16 through a pipe to realize the delivery of filtered gas.

[0038] Please see the appendix Figure 6 The filter assembly 14 includes a first push post 141, one end of which is fixedly connected to the outside of one side of the push frame 13, and the other side of the first push post 141 is fixedly connected to a first piston post 142. A spring 144 is fixedly connected inside the filter cylinder 15, and the other end of the spring 144 is fixedly connected to a filter plate 143. The filter plate 143 is slidably connected to the inside of the filter cylinder 15.

[0039] Specifically, the first push column 141 slides with the reciprocating linear motion of the push frame 13, transmitting the power of the push frame 13 to the first piston column 142. The first piston column 142 can reciprocate linearly within the filter cylinder 15 with the movement of the first push column 141, pushing the gas inside the filter cylinder 15 to act on the filter plate 143, thus assisting in the filtration action. The filter plate 143 can slide along the inside of the filter cylinder 15, and its plate body is provided with filter channels for adsorbing and filtering the moisture in the hydrogen-containing gas entering the filter cylinder 15. The other side of the spring 144 is in contact with the first piston column 142, and reciprocates under the action of the thrust of the first piston column 142 and the elastic force of the spring 144, preventing the filter channels from being blocked. When the filter plate 143 slides in the direction of compression of the spring 144 due to the thrust of the first piston column 142, the spring 144 is compressed and stores elastic potential energy. When the first piston column 142 retracts, the spring 144 releases elastic potential energy, driving the filter plate 143 to reset, thus realizing the reciprocating vibration of the filter plate 143.

[0040] Please see the appendix Figure 2 and attached Figure 6 A metering cylinder 16 is fixedly connected to the other side of the outer shell 10, a pushing assembly 17 is provided on the other side of the pushing frame 13, and the bottom of the denitrifier 18 is fixedly connected to the other end of the metering cylinder 16.

[0041] Specifically, the metering cylinder 16 forms a sealed metering chamber inside, which is used to receive the gas delivered by the filter cylinder 15 and perform quantitative control to provide a stable flow of gas for the subsequent denitrification process. The push assembly 17 is used to quantitatively push the gas inside the metering cylinder 16 into the denitrifier 18. The hydrogen purified by the denitrifier 18 can be discharged through the gas outlet pipe 19 and delivered to the hydrogen inlet of the fuel cell or the hydrogen storage device to complete the hydrogen return process.

[0042] Please see the appendix Figure 7 The pushing assembly 17 includes a second pushing column 171, one end of which is fixedly connected to the outside of the other side of the pushing frame 13, and the other end of which is fixedly connected to a second piston column 172. The outside of the second piston column 172 is slidably connected to the inside of the metering cylinder 16.

[0043] Specifically, when the push frame 13 moves away from the metering cylinder 16, it drives the second push column 171 to retract synchronously, and the second piston column 172 slides outward from the metering cylinder 16. The volume of the inner chamber of the metering cylinder 16 increases, creating a negative pressure. Filtered gas is drawn in through the pipe connected to the filter cylinder 15. When the push frame 13 moves closer to the metering cylinder 16, it pushes the second push column 171 and the second piston column 172 to slide inward from the metering cylinder 16. The volume of the chamber decreases, and the metered gas is compressed to the denitrifier 18, thus realizing the metered delivery of gas.

[0044] Please see the appendix Figure 6 The filter cylinder 15 and the metering cylinder 16 are connected by a pipe;

[0045] Specifically, the two ends of the pipe are fixed to the air outlet of the filter cylinder 15 and the air inlet of the metering cylinder 16, respectively, to ensure that the relative position of the pipe and the interface of the two cylinders is fixed and cannot be displaced or loosened. This pipe is the conveying channel for the filtered hydrogen-containing gas. The hydrogen-containing gas inside the filter cylinder 15, after the water is filtered out by the filter plate 143, flows into the internal chamber of the metering cylinder 16 through this pipe.

[0046] Please see the appendix Figure 2 and attached Figure 6 The external drive shaft 11 is rotatably connected to the inside of the housing 1, and the external drive shaft 11 is rotatably connected to the inside of the outer casing 10;

[0047] Specifically, the outer casing 10 and the housing 1 are used to support the rotation of the drive shaft 11, so that the drive shaft 11 can stably transmit power under the drive of the drive wheel 3, and synchronously drive the push column 12 to perform eccentric circular motion.

[0048] Please see the appendix Figure 6 and attached Figure 7 The outer side of the first push post 141 is slidably connected to the inside of the housing 10, and the outer side of the second push post 171 is slidably connected to the inside of the housing 10;

[0049] Specifically, the two push columns pass through the double sliding holes of the housing 10, making the reciprocating motion of the first push column 141 and the second push column 171 smoother, avoiding insufficient filtration and inaccurate quantification caused by the displacement of the push column movement.

[0050] Work process: When the hydrogen regeneration system of this fuel cell is needed, the motor 2 is started to output power, which drives the two drive wheels 3 to rotate synchronously through the transmission belt 4. The hydrogen-containing gas enters the rotating tube 56 through the inlet pipe 9 and then flows into the condenser 6.

[0051] The transmission wheel 3 drives the first transmission plate 51 to rotate, and transmits power to the rotating disk 53 through the second rotating plate 52. The rotating disk 53 drives the toothed plate 54 to slide back and forth, and through meshing, drives the first gear 55 and the rotating tube 56 to rotate, thereby causing the heat-conducting plate 57 and the condenser tube 58 to rotate synchronously in the condenser cylinder 6. The condenser tube 58 condenses the gaseous water in the gas into liquid through heat exchange. The condensate flows into the water storage tank 7 through the pipe for collection. At the same time, the heat-conducting plate 57 drives the fixed column 83 to rotate, and the push plate 82 performs linear reciprocating motion under the constraint of the lead screw 81, which drives the gas plate 84 to push the gas, promotes full contact between the gas and the condenser tube 58, and accelerates the gas to be transported towards the filter cylinder 15.

[0052] Next, the transmission wheel 3 drives the transmission shaft 11 on the other side to rotate synchronously. The push column 12 on the transmission shaft 11 performs eccentric circular motion, which drives the push frame 13 to perform reciprocating linear motion through the elongated hole of the push frame 13. The push frame 13 drives the first push column 141 and the first piston column 142 to reciprocate within the filter cylinder 15. The first piston column 142 pushes the gas through the filter plate 143, which adsorbs residual moisture in the gas. At the same time, the spring 144 drives the filter plate 143 to vibrate back and forth under the action of thrust and elasticity, avoiding blockage of the filter channel and ensuring the filtration effect. Thus, the moisture in the gas can be fully removed, and the efficiency of moisture filtration can be improved.

[0053] The filtered gas flows from the filter cylinder 15 into the metering cylinder 16 through the pipe. The push frame 13 synchronously drives the second push column 171 and the second piston column 172 to reciprocate within the metering cylinder 16. When the second piston column 172 retracts, a negative pressure is formed inside the metering cylinder 16 to draw in the gas. When the second piston column 172 advances, the metered gas is compressed to the denitrifier 18. The denitrifier 18 removes the nitrogen component from the gas, achieving hydrogen purification. The purified qualified hydrogen is discharged through the outlet pipe 19 and transported to the hydrogen inlet of the fuel cell or the storage device, completing the entire hydrogen return process. This achieves the effect of metered gas delivery, allowing the denitrifier 18 to fully remove nitrogen from the gas.
