Description

Technical Field

[0001] This utility model relates to the field of separator technology, specifically a hydrogen vapor-water separator. Background Technology

[0002] A hydrogen vapor-liquid separator is a device used to remove liquid water from hydrogen. It plays an important role in the process of hydrogen production by water electrolysis. Through its efficient gas-liquid separation function, it can ensure that liquid water in hydrogen is effectively removed, thereby improving the purity and quality of hydrogen.

[0003] A hydrogen vapor-water separator for a fuel cell, application number CN201810854267.5, includes a main body and a cover plate mounted on the main body. The cover plate and the main body form a sealed cavity. The main body includes a bottom plate and side plates extending upward from the bottom plate. The sealed cavity has a separation region and an adsorption region communicating with the separation region. The side plates each have a first side edge, a second side edge, and a third side edge located on both sides of the first side edge. The hydrogen vapor-water separator for the fuel cell further includes a first guide plate, a second guide plate, and a third guide plate located in the separation region and causing hydrogen to flow in a spiral motion. By using multiple guide plates to achieve repeated vortex flow of hydrogen, repeated centrifugal force is generated on the high-speed exhaust hydrogen, achieving a highly efficient separation effect between liquid water droplets and hydrogen.

[0004] The device uses multiple guide vanes to repeatedly vortex and guide hydrogen, generating repeated centrifugal force on the high-speed exhaust hydrogen, achieving efficient separation of liquid water droplets and hydrogen. However, the centrifugal force generated by the guide vanes is too small to completely separate liquid water droplets and hydrogen in the hydrogen-water mixture, thus affecting the recovery effect of hydrogen and water droplets.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing hydrogen vapor-water separator structure. Utility Model Content

[0006] The purpose of this invention is to provide a hydrogen vapor-water separator to solve the problem mentioned in the background art that the centrifugal force generated by the guide plate is too small to completely separate liquid water droplets and hydrogen in the hydrogen vapor-water mixture, thus affecting the recovery effect of hydrogen and water droplets.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen vapor-water separator, comprising a body, a connecting pipe fixedly connected to the outside of the body, and a filter screen fixedly installed inside the connecting pipe; a water outlet pipe fixedly connected to the bottom of the body; a separation component installed inside the body; and a water outlet component installed inside the body, with the water outlet component and the water outlet pipe distributed vertically in correspondence. The separation component can separate the hydrogen vapor-water mixture inside the body; and the water outlet component can discharge the water accumulated inside the body.

[0008] Preferably, the separation assembly includes a first drainage plate, a second drainage plate, and a third drainage plate. The first drainage plate is fixedly connected to the inside of the device body, the second drainage plate is fixedly connected to the inside of the device body, and the third drainage plate is fixedly connected to the inside of the device body. The first drainage plate, the second drainage plate, and the third drainage plate are arranged sequentially from left to right along the device body cavity. The first drainage plate, the second drainage plate, and the third drainage plate divide the inside of the device body cavity into three sets of separation chambers, and the three sets of separation chambers are interconnected.

[0009] Preferably, the separation component further includes a servo motor and a spiral plate, wherein the servo motor is fixedly installed on the outside of the device body, and the spiral plate is fixedly installed at the output end of the servo motor.

[0010] Preferably, the separation assembly further includes a hydrogen collector, a gas pipe, and a check valve. The hydrogen collector is fixedly installed on the outside of the apparatus and is connected to the inner cavity of the apparatus through the gas pipe. A check valve is installed on the outside of the gas pipe.

[0011] Preferably, the water outlet assembly includes a sealing plate, a connecting rod, and a sliding groove. The sealing plate is disposed at the upper end of the water outlet pipe, and a connecting rod is fixedly connected to the outer side of the sealing plate. The connecting rod is nested inside the sliding groove, and the sliding groove is formed in the body of the device.

[0012] Preferably, the water outlet assembly further includes a float plate, which is fixedly installed on the outside of the connecting rod.

[0013] Preferably, the water outlet assembly further includes a traction rope and a pull ring. The traction rope is fixedly connected to the outside of the float and passes through the inside of the device body. A pull ring is fixedly connected to the end of the traction rope.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the hydrogen vapor-water separator is equipped with:

[0015] 1. Separation structure: This structure divides the inner side of the apparatus into multiple separation chambers by sequentially installing a first guide plate, a second guide plate, and a third guide plate inside the apparatus. When the hydrogen-water mixture enters the inner side of the apparatus, the special arc-shaped structure of the first, second, and third guide plates generates repeated vortices to guide the hydrogen gas, thereby generating centrifugal force in the hydrogen-water mixture, causing larger water droplets to be separated from the hydrogen gas by centrifugal force.

[0016] Furthermore, the incompletely separated hydrogen-water mixture is separated by multiple sets of guide vanes and then flows to the right side of the reactor cavity. At this time, the servo motor is activated, and the output of the servo motor drives the spiral plate to rotate. The rotation of the spiral plate will cause the hydrogen-water mixture, which is still in a vortex state, to rotate a second time. Through rotation at different angles, the hydrogen-water mixture generates lateral centrifugal force, which causes the hydrogen and water in the hydrogen-water mixture to be separated a second time, improving the separation effect of water droplets and hydrogen. The separated hydrogen will enter the hydrogen collector through the gas pipe for storage, while the water droplets will accumulate at the bottom of the reactor due to their own gravity.

[0017] 2. Water outlet structure: As water droplets accumulate, the water level at the bottom of the vessel will continuously rise. As the water level rises, the float will move upward. When the float rises to a certain height, it will drive the connecting rod to move upward along the inside of the groove. The upward movement of the connecting rod will drive the connecting sealing plate to move upward as well. The upward movement of the sealing plate will open the water outlet pipe, allowing the water inside the vessel to be discharged through the water outlet pipe, achieving the effect of automatic water discharge.

[0018] Furthermore, when drainage is needed, the pull ring can be manually pulled, which will cause the traction rope to exert a pulling force on the float, thereby moving the sealing plate upward and opening the water outlet pipe to achieve the effect of manual drainage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a hydrogen vapor-water separator, comprising:

[0028] Example 1: As Figure 1-Figure 5 The present invention provides a technical solution: a hydrogen vapor-water separator, comprising: a body 1, with a connecting pipe 2 fixedly connected to the outside of the body 1 and a filter screen 3 fixedly installed inside the connecting pipe 2; a water outlet pipe 4 fixedly connected to the bottom of the body 1; a separation component 5 installed inside the body 1; and a water outlet component 6 installed inside the body 1, with the water outlet component 6 and the water outlet pipe 4 distributed vertically in correspondence. The separation component 5 can separate the hydrogen vapor-water mixture inside the body 1, and the water outlet component 6 can discharge the water accumulated inside the body 1.

[0029] The separation component 5 includes a first drainage plate 501, a second drainage plate 502, and a third drainage plate 503. The first drainage plate 501 is fixedly connected to the inside of the device body 1, the second drainage plate 502 is fixedly connected to the inside of the device body 1, and the third drainage plate 503 is fixedly connected to the inside of the device body 1. The first drainage plate 501, the second drainage plate 502, and the third drainage plate 503 are arranged sequentially from left to right along the cavity of the device body 1, dividing the inner side of the cavity of the device body 1 into three separation groups. The separation assembly 5 includes a servo motor 504 and a spiral plate 505. The servo motor 504 is fixedly installed on the outside of the device body 1, and the spiral plate 505 is fixedly installed on the output end of the servo motor 504. The separation assembly 5 also includes a hydrogen collector 506, a gas pipe 507 and a check valve 508. The hydrogen collector 506 is fixedly installed on the outside of the device body 1, and the hydrogen collector 506 is connected to the inner cavity of the device body 1 through the gas pipe 507. The check valve 508 is installed on the outside of the gas pipe 507.

[0030] This structure, by sequentially installing a first guide plate 501, a second guide plate 502, and a third guide plate 503 on the inner side of the container 1, divides the inner side of the container 1 into multiple separation chambers. When the hydrogen-water mixture enters the inner side of the container 1, the special arc-shaped structure of the first guide plate 501, the second guide plate 502, and the third guide plate 503 generates repeated vortices to guide the hydrogen gas, thereby generating centrifugal force in the hydrogen-water mixture. Larger water droplets are separated from the hydrogen gas by centrifugal force. At this point, any remaining water droplets are separated from the hydrogen gas. After being separated by multiple sets of guide vanes, the hydrogen-water mixture arrives at the right side of the chamber 1. At this time, the servo motor 504 is activated, and the output of the servo motor 504 drives the spiral plate 505 to rotate. The rotation of the spiral plate 505 will cause the hydrogen-water mixture, which is still in a vortex state, to rotate a second time. Through rotation at different angles, the hydrogen-water mixture generates a lateral centrifugal force, which causes the hydrogen and water in the hydrogen-water mixture to be separated a second time, improving the separation effect of water droplets and hydrogen gas. The separated hydrogen gas will enter the hydrogen collector 506 through the gas pipe 507 for storage, while the water droplets will accumulate at the bottom of the chamber 1 due to their own gravity.

[0031] Example 2: Figure 1-Figure 2 , Figure 6The present invention provides a technical solution: a hydrogen vapor-water separator, which discloses that: the water outlet component 6 includes a sealing plate 601, a connecting rod 602, and a sliding groove 603. The sealing plate 601 is disposed at the upper end of the water outlet pipe 4, and the connecting rod 602 is fixedly connected to the outer side of the sealing plate 601. The connecting rod 602 is nested inside the sliding groove 603, and the sliding groove 603 is opened in the body 1; the water outlet component 6 also includes a float plate 604, which is fixedly installed on the outer side of the connecting rod 602; the water outlet component 6 also includes a traction rope 605 and a pull ring 606. The traction rope 605 is fixedly connected to the outer side of the float plate 604, and the traction rope 605 passes through the inner side of the body 1, and the pull ring 606 is fixedly connected to the tail end of the traction rope 605;

[0032] As water droplets accumulate, the water level at the bottom of the container 1 rises continuously. As the water level rises, the float 604 moves upward. When the float 604 reaches a certain height, it drives the connecting rod 602 to move upward along the inside of the groove 603. The upward movement of the connecting rod 602 causes the sealing plate 601 to move upward as well. The upward movement of the sealing plate 601 opens the outlet pipe 4, allowing water inside the container 1 to be discharged through the outlet pipe 4, achieving automatic water discharge. When drainage is needed, the pull ring 606 can be manually pulled, causing the traction rope 605 to exert a pulling force on the float 604, which in turn moves the sealing plate 601 upward, opening the outlet pipe 4 and achieving manual drainage.
