Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen and water separation devices, and in particular to a hydrogen and water separation device for a hydrogen fuel cell system. Background Art

[0002] A hydrogen fuel cell system is a device that uses the electrochemical reaction of hydrogen and oxygen to generate electricity, water, and heat. Most of the water in the electrochemical reaction is discharged through the air outlet, and a part of the water diffuses to the hydrogen side through the proton exchange membrane, and is discharged from the stack through the hydrogen outlet together with the incompletely reacted hydrogen. In order to remove the water vapor mixed in the discharged hydrogen, it enters the hydrogen cycle again through the hydrogen circulation pump. Therefore, a device is needed to separate the hydrogen and water after the hydrogen fuel cell reaction to improve the utilization rate of hydrogen. When the hydrogen fuel cell is turned on and off and cold-started, if the liquid water produced by the reaction in the flow channel is not discharged in time, it will cause water flooding and hydrogen-air interface. The carbon carrier on the membrane will be oxidized and corroded by water. The above phenomenon is more serious when it freezes in winter. Therefore, it is necessary to design a hydrogen and water separation device for a hydrogen fuel cell system to solve the problem that the existing hydrogen and water separation efficiency is low, and the water in the separation device cannot be discharged when the weather temperature is low, especially when it is started at low temperatures in winter.

[0003] After searching, the Chinese patent application number CN201820723233.8 discloses a hydrogen water separation device for a hydrogen fuel cell vehicle, including a battery pack housing, a separator installed inside the battery pack housing, the top of the separator is connected to an air inlet, and the outer walls on both sides of the separator adjacent to the air inlet are respectively connected to an oxygen exhaust pipe and a hydrogen exhaust pipe, and the inner top of the separator is fixedly connected to a motor by bolts.

[0004] The hydrogen-water separation device for a hydrogen fuel cell vehicle in the above patent has the following deficiencies: during the separation of hydrogen and water, most of the liquid water moves to the bottom under the action of centrifugation, and a small amount of liquid water is mixed in the hydrogen in the middle layer and cannot be effectively separated, resulting in incomplete separation. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that during the process of separating hydrogen and water, most of the liquid water moves to the bottom under the action of centrifuge, and a small amount of liquid water is mixed with the hydrogen in the middle layer and cannot be effectively separated, resulting in incomplete separation. A hydrogen and water separation device for a hydrogen fuel cell system is proposed to solve the problem.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A hydrogen and water separation device for a hydrogen fuel cell system comprises a fixing seat 1, a support frame is arranged on the top outer wall of the fixing seat 1, a mounting seat is arranged on the top outer wall of the supporting frame, a separator control body is arranged on the top outer wall of the mounting seat, a fixing seat 2 is arranged on the top outer wall of the separator control body, a drainage pipe, a hydrogen inlet pipe, a hydrogen return pipe and a hydrogen discharge pipe are arranged on the circumferential outer wall of the separator control body, a heating solenoid valve is arranged on one end of the drainage pipe, a clamping plate is arranged on the circumferential inner wall of the separator control body, and two clamping plates are clamped on the bottom outer wall of the clamping plate.

[0008] Preferably: the top outer wall of the base is slidably connected to two or more sliding columns, the bottom inner wall of the sliding column and the bottom outer wall of the base are clamped with the same spring 2, the top outer walls of the two or more sliding columns are provided with the same top plate, the top outer wall of the top plate is provided with a accommodating tube, and the inner wall of the accommodating tube is movably connected with a universal ball.

[0009] Preferably, an electric push rod is provided on a top outer wall of the fixing seat, a connecting plate is provided on an output end of the electric push rod, and a lifting plate is welded on an outer wall of one side of the connecting plate.

[0010] As a preferred embodiment of the present invention: the top outer wall of the lifting plate is provided with more than two guide posts, and the top outer walls of the two or more guide posts are provided with the same bottom plate.

[0011] As a preferred embodiment of the present invention: a bearing is provided on the top outer wall of the bottom plate, and the bearing is rotatably connected to the circumferential outer wall of the rotating cylinder.

[0012] As a preferred embodiment of the present invention: a liquid level sensor is provided on the circumferential outer wall of the separator control body.

[0013] Furthermore: a sponge is bonded to the outer circumferential wall of the rotating cylinder, a filter plate is arranged on the outer circumferential wall of the rotating cylinder, and a pressing plate is arranged on the inner circumferential wall of the separator control body.

In the process of the mixed gas of hydrogen and high-temperature water vapor entering the separator control body, the cross-sectional area suddenly increases, thereby reducing the flow rate of the gas.

The gas after two separations is basically hydrogen, which flows out through the internal channel and the hydrogen return pipe and returns to the fuel cell stack for recycling, or the remaining hydrogen is discharged to the tail exhaust mixer through the hydrogen exhaust pipe during the shutdown and purge of the fuel cell system.

[0019] 2. Liquid water can be discharged by setting a drain pipe. The heating solenoid valve can solve the problem that the water in the separation device freezes and cannot be discharged when the weather temperature is low, especially when it is started at low temperatures in winter.

[0020] 3. A rotating cylinder is provided that can slide along the circumferential outer wall of the rotating rod, and the sliding direction of the rotating cylinder can be limited by the positioning column and the rectangular hole, thereby preventing the rotating cylinder from detaching. The rotating cylinder can drive the universal ball in the accommodating cylinder to rise during the rising process, so that the universal ball can generate pressure on the bottom of the defogger, so that the spring 1 can perform reciprocating compression and rebound motion, thereby accelerating the falling rate of the liquid water in the defogger.

[0021] 4. By providing an electric push rod, the output end can be controlled to rise, so that the height of the lifting plate can be adjusted, thereby adjusting the height of the rotating cylinder. At the same time, by providing a bearing, the servo motor can drive the rotating cylinder to rotate during the rising and falling process of the rotating cylinder, and the outer wall of the guide column is slidably connected to the outer wall of the bottom of the mounting seat.

[0022] 5. The sponge can be provided so that the rotating cylinder can absorb the liquid water attached to the inner wall of the circumference of the separator control body during the rising process. At the same time, as the rotating cylinder continues to rise, the crimping plate can generate an extrusion force on the surface of the sponge, so that the liquid water in the sponge can be squeezed out and fall to the bottom of the mounting seat under the action of gravity. At the same time, the impurities in the liquid water can be filtered by providing a filter plate. BRIEF DESCRIPTION OF THE DRAWINGS

In the process of the mixed gas of hydrogen and high-temperature water vapor entering the separator control body 5, the cross-sectional area suddenly increases, thereby reducing the flow rate of the gas. Since the gas inertia is small and the water droplet inertia is large, the gas moves upward, and the liquid water flows into the bottom position of the mounting seat 7 under the action of gravity.

The rotating cylinder 19 can drive the universal ball 35 in the accommodating cylinder 34 to rise during the rising process, so that the universal ball 35 can generate pressure on the bottom of the defogger 14, so that the spring 15 can perform reciprocating compression and rebound movement, so as to accelerate the falling rate of the liquid water in the defogger 14. At the same time, the spring 2 30 can be provided to buffer and protect the universal ball 35. At the same time, when the servo motor 21 drives the rotating rod 22 to rotate, the spherical outer wall of the universal ball 35 can also roll along the outer wall of the bottom of the defogger 14, so as to protect the defogger 14. ;

[0038] In order to facilitate the control of the lifting of the rotating drum 19; Figure 1-6 As shown, an electric push rod 8 is fixed to the top outer wall of the fixing seat 1 by bolts, and a connecting plate 9 is fixed to the output end of the electric push rod 8 by bolts, and a lifting plate 26 is welded to the outer wall of one side of the connecting plate 9, and two or more guide columns 23 are fixed to the top outer wall of the lifting plate 26 by bolts, and the top outer walls of the two or more guide columns 23 are fixed to the same bottom plate 20 by bolts, and a bearing 25 is provided on the top outer wall of the bottom plate 20, and the bearing 25 is rotatably connected to the circumferential outer wall of the rotating cylinder 19; by providing the electric push rod 8, its output end can be controlled to rise, so that the height of the lifting plate 26 can be adjusted, so that the height of the rotating cylinder 19 can be adjusted, and at the same time, by providing the bearing 25, the servo motor 21 can drive the rotating cylinder 19 to rotate during the rising and falling process of the rotating cylinder 19, and the circumferential outer wall of the guide column 23 is slidably connected to the bottom outer wall of the mounting seat 7.

Since the gas inertia is small and the water droplet inertia is large, the gas moves upward, and the liquid water flows into the lower liquid collector under the action of gravity.

[0043] In order to speed up the separation rate of the mixed gas of hydrogen and high-temperature water vapor; Figure 5 As shown, the centrifugal frame 24 is fixed to the outer circumferential wall of the mounting column 31 by bolts; by providing the centrifugal frame 24, the centrifugal force can be used to accelerate the separation rate and separation effect between liquid water and hydrogen during the high-speed rotation of the rectangular hole 32.

[0044] When this embodiment is in use, during the separation process between liquid water and hydrogen, the liquid water will adhere to the circumferential inner wall of the separator control body 5 after condensation. By controlling the up and down movement of the rotating cylinder 19, the sponge 18 can slide up and down along the circumferential inner wall of the separator control body 5, so that the sponge 18 can absorb the liquid water attached to the circumferential inner wall of the separator control body 5. At the same time, when pressure is generated between the top of the sponge 18 and the bottom of the crimping plate 13, the liquid water in the sponge 18 can be squeezed out, so that the liquid water can fall into the inside of the mounting seat 7 under the action of gravity, and finally be discharged through the heating solenoid valve 36 on the drain pipe 3. At the same time, the impurities in the liquid water can be filtered by providing a filter plate 33, and the high-speed rotation of the centrifugal frame 24 can generate centrifugal force, thereby accelerating the separation rate and separation effect between liquid water and hydrogen.
