Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid separation, in particular to a gas-liquid separation device for a water electrolysis hydrogen production system. Background Art

[0002] When hydrogen is produced by electrolysis of water, the temperature of hydrogen and oxygen is high when they are discharged from the electrolytic cell, and water vapor is mixed in the gas. The gas then needs to be cooled and the water separated. Usually, the gas will first be discharged into a gas-liquid separator to separate the gas from the electrolyte retained therein, and then the gas will be cooled separately using a cooler. Shell and tube or plate coolers are usually used to cool the gas, but due to the presence of water vapor in the gas, the water vapor is easily condensed into droplets after the gas is cooled, and the droplets are likely to affect the heat transfer efficiency of the cooler, resulting in a decrease in the heat transfer efficiency of the cooler, obstructed gas circulation, and an increased risk of equipment corrosion, which is relatively inconvenient.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The gas is transported through a connecting pipe and passed through a serpentine tube composed of multiple separation mechanisms, elbows, hoses and connecting pipes. The gas is cooled by the separation mechanism when passing through the separation mechanism, and the water vapor in the gas is condensed into droplets. The condensed droplets in the separation mechanism are then cleaned by a collection mechanism, thereby facilitating the separation of water in the gas.

[0015] 2. By starting multiple auxiliary electric push rods and multiple main electric push rods to control the movement of adjacent moving plates and push plates, the moving tube moves to make multiple rings in the separation mechanism collide with each other, so that the multiple rings are close together. The metal rods on the multiple rings are staggered and densely arranged due to different angles, so that the multiple metal rods on the multiple rings form a densely meshed filter material. Then the cooling unit reduces the temperature of the rings and metal rods. When the gas passes through the metal rods, the flow cross-section will be reduced, which improves the heat exchange efficiency between the gas and the metal rods, thereby improving the gas cooling efficiency and causing the droplets to condense on the metal rods. 3. By controlling the movement of the moving plate, the two moving tubes on the separation mechanism drive the connected ring bodies to move away from each other, so that the connecting rope pulls the guide rail to move toward the ring body. The guide rail presses the metal sleeve to tilt, thereby forcing multiple ring bodies to separate from each other. Then, the separation mechanism is activated by the push plate, so that the upper cover plate of the separation mechanism moves to close the adjacent cover shells and the embedded ring enters between the two adjacent ring bodies. Then, the moving tube moves so that the ring bodies and the embedded rings are staggered and tightly attached together. Then, compressed air is delivered by the air pump to flush the liquid droplets on the adjacent ring bodies and metal rods. The compressed air and liquid droplets are discharged through the water pipe, thereby facilitating the cleaning of condensed liquid droplets. 4. When the collection mechanism is used to clean the condensed liquid droplets, the gas can flow through the interior of the cover from the vents on the embedded rings at both ends. When the separation mechanism is used to condense the liquid droplets in the gas on the metal rod, the gas is cooled by the filter material formed by the close contact of multiple rings. After the condensed liquid droplets are cleaned by the collection mechanism, the multiple rings can be separated by moving the moving tube, and the rings can push the adjacent embedded rings and the box body to reset. Then, the cover plate and the multiple embedded rings can be driven out of the cover by the push plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-10 In an embodiment of the present invention, a gas-liquid separation device of a water electrolysis hydrogen production system includes: The cabinet 100, a cooling unit 200 for providing cold air, a plurality of separation mechanisms 300 and a plurality of collection mechanisms 400, the cabinet 100 is fixedly connected to connecting pipes 110 on both sides of the cabinet 100, and the two connecting pipes 110 are respectively close to the top and bottom ends of the cabinet 100, a plurality of elbows 120 are arranged between the two connecting pipes 110, and the plurality of elbows 120 are respectively fixedly connected to the two opposite inner walls of the cabinet 100, the plurality of elbows 120 on the opposite sides of the cabinet 100 are staggered, the cooling unit 200 is fixedly connected to the top of the cabinet 100, the plurality of separation mechanisms 300 are all located inside the cabinet 100, the separation mechanism 300 includes two movable pipes 310, and the two movable pipes 310 are respectively fixed to the inner walls of the cabinet 100. 10 The outer side walls are all slidably sleeved with a ring 320, and the outer side wall of any ring 320 is fixedly connected to a rod body 321, and any rod body 321 is fixedly connected to the cabinet 100. A plurality of ring bodies 330 are arranged between the two movable tubes 310, wherein the ring bodies 330 located at both ends are respectively fixedly connected to the two movable tubes 310, and the inner side wall of any ring body 330 is fixedly connected to a plurality of metal rods 331 arranged in sequence, and a hose 311 is fixedly connected between any bent pipe 120 and any connecting pipe 110 and the adjacent movable tube 310, and a plurality of collecting mechanisms 400 are all located inside the cabinet 100, and the plurality of collecting mechanisms 400 correspond one-to-one to the plurality of separation mechanisms 300.

[0020] Specifically, two connecting pipes 110, multiple moving pipes 310 on the separation mechanisms 300, multiple flexible pipes 311, and multiple curved pipes 120 form a serpentine pipe. Gas produced by electrolyzing water is transported into a gas-liquid separator to separate the electrolyte from the gas. The gas is then fed into one connecting pipe 110 through a pipeline and discharged from the other connecting pipe 110 along the serpentine pipe formed by the connecting pipe 110, flexible pipe 311, and moving pipe 310 for the next process. In this embodiment, the cooling unit 200 can provide cold air to the inside of the cabinet 100 to keep the temperature of the interior space of the cabinet 100 low. The cooling unit 200 can be an existing device such as an air cooler, which will not be described in detail here. In the initial state, the multiple ring bodies 330 in any separation mechanism 300 are in a close contact state under the pressure of two adjacent moving tubes 310, so that the gas can be transported through the space between the multiple ring bodies 330. The ring bodies 330 and the metal rods 331 can be made of materials with good thermal conductivity such as copper, so that the cooling unit 20 The cold air provided by the ring bodies 330 can keep the ring bodies 330 and the metal rods 331 at a relatively low temperature. In addition, the multiple ring bodies 330 are arranged at different angles, so that the metal rods 331 on the multiple ring bodies 330 are densely interlaced. Thus, the metal rods 331 on the multiple ring bodies 330 form a filter material with dense meshes. The gas passing through the multiple ring bodies 330 exchanges heat with the densely interlaced metal rods 331 to cool down, reducing the gas flow cross-section, improving the gas cooling effect, and causing water vapor in the gas to condense into droplets that condense on the metal rods 331. In this embodiment, when it is necessary to clean the condensed droplets on the metal rod 331, the two movable tubes 310 in the separation mechanism 300 can be pulled apart to separate the multiple ring bodies 330 from each other. The number of metal rods 331 arranged on a single ring body 330 is relatively small, thereby facilitating the cleaning of the metal rods 331 on the ring body 330.

[0021] Example 1

[0022] like Figure 2-Figure 7 As shown, in this embodiment, the outer wall of any ring body 330 is fixedly connected with a plurality of connecting rings 301, a plurality of sliding rods 323 are provided between the two rings 320 in any separation mechanism 300, and any sliding rod 323 is movably inserted into the adjacent connecting ring 301, and a plurality of notches are opened on the outer wall of any ring 320, and any sliding rod 323 is movably engaged with the adjacent notches, and a plurality of guide rails 340 arranged parallel to each other are provided between the two moving tubes 310 in any separation mechanism 300, and any guide rail 340 is fixedly connected with a guide ring 341 at both ends, and a positioning rod 322 is slidably sleeved inside any guide ring 341, and any positioning rod 322 is fixedly connected to the adjacent ring 320, and the positioning rods 322 at both ends of any guide rail 340 are respectively located at two adjacent rings 320. 0 are all equipped with connecting ropes, and the outer side wall of any connecting rope is slidably sleeved with a slider 351, and any slider 351 is slidably clamped inside the adjacent guide rail 340, and any connecting ring 301 is fixedly connected with a convex ring 302, and any connecting rope passes through the adjacent convex rings 302 in sequence, and the outer side wall of the connecting rope is movably sleeved with multiple metal sleeves 350, and any metal sleeve 350 is located between the convex ring 302 and the adjacent slider 351, and a rebound spring 342 is fixedly connected between any guide ring 341 and the adjacent sleeve 320, and a cover shell 360 is detachably connected between the two sleeves 320 in any separation mechanism 300, and the two sleeves 320 and any ring body 330 in any separation mechanism 300 are located inside the adjacent cover shell 360, and any cover shell 360 includes two shells, and a rectangular hole is opened on one side of the two shells.

[0023] In this embodiment, when it is necessary to adjust the angles of the multiple ring bodies 330 on the separation mechanism 300 to adjust the internal mesh density of the filter material formed by the multiple ring bodies 330 sticking together, the multiple sliding rods 323 on any separation mechanism 300 can be pulled out from the notch to separate the sliding rods 323 from the adjacent connecting rings 301, so that the ring bodies 330 except those connected to the moving tube 310 are all in a scattered state, and the multiple connecting ropes and metal sleeves 350 are disassembled to separate any connecting rope from the convex ring 302, so that the ring bodies 330 can be manually arranged at the angles of the metal rods 331 on each ring body 330. After the adjustment is completed, slide each ring body 330 to adjust the mesh density of the filter material formed by the multiple ring bodies 330. The multiple sliders 351 on the guide rail 340 are positioned so that any slider 351 is located between two adjacent ring bodies 330. The connecting rope is then passed through the adjacent protruding rings 302 and the sliders 351 in sequence to form a serpentine shape. The connecting rope is then covered with multiple metal sleeves 350, and the two ends of the connecting rope are adhered and fixed to the two protruding rings 302 at the two ends by glue. The sliding rods 323 are then passed through the connecting rings 301 to arrange the multiple ring bodies 330 in parallel. The multiple sliding rods 323 are then inserted into the notches to fix the positions of the multiple ring bodies 330. The cover 360 can then be installed on the two collars 320 so that the rectangular holes of the two shells on the cover 360 are aligned and merged. When the two moving tubes 310 are moved toward each other, the two moving tubes 310 can naturally squeeze the multiple ring bodies 330 to slide along the sliding rod 323 and stick together. When the two moving tubes 310 are pulled away from each other, the two moving tubes 310 can pull the connected ring bodies 330 to move, so that the two ends of the connecting rope move away from each other. Since the connecting rope portion between any protrusion and the adjacent slider 351 is covered with a metal sleeve 350 and is of equal length, the connecting rope will pull the guide rail 340 toward the ring body 330 through the slider 351. The guide rail 340 is kept flat due to the limit of the guide ring 341 and the positioning rod 322, so that the guide rail 340 presses the multiple metal sleeves 350 to tilt and drive the multiple ring bodies 330 to naturally separate the same distance, thereby facilitating the adjustment of the spacing between the multiple ring bodies 330. When the two moving tubes 310 move toward each other, the rebound spring 342 can push the guide rail 340 away from the ring body 330.

[0024] like Figure 3 and Figure 8-Figure 9 As shown, in this embodiment, the collection mechanism 400 includes: The cover plate 410, the slide rail 420, the multiple box bodies 430 and the multiple embedded rings 440 for closing the two rectangular holes on the cover shell 360, the cover plate 410 is located between the two rod bodies 321 in the corresponding separation mechanism 300, the slide rail 420 is fixedly connected to the cover plate 410, and one end of the multiple box bodies 430 are slidably connected to the inside of the slide rail 420. Any box body 430 includes two inner cavities, wherein one inner cavity is connected to the air pump through a conduit, and the other inner cavity is fixedly connected to a water pipe. The multiple embedded rings 440 are connected to the inner cavity. Multiple box bodies 430 correspond to each other one by one, and any embedded ring 440 is fixedly connected to the corresponding box body 430. A partition 441 is fixedly sleeved inside any embedded ring 440. The two inner cavities of any box body 430 are connected to the interior of the adjacent embedded ring 440, and the inner cavity of any box body 430 is respectively located on the opposite sides of the adjacent partition 441. The outer walls of the two embedded rings 440 at both ends are provided with multiple ventilation holes. The embedded rings 440 at both ends in any collecting mechanism 400 are movably connected with adsorption plates 431.

[0025] In a specific implementation, when the multiple ring bodies 330 on the separation mechanism 300 are separated from each other, the adsorption plates 431 are inserted into the inner cavity of the box body 430 at both ends to seal it, and the cover plate 410 can be moved to seal the adjacent cover shells 360, and the embedded ring 440 is moved into the space between two adjacent ring bodies 330, and then the moving tube 310 is moved to make the multiple ring bodies 330 and the multiple embedded rings 440 interlaced and attached to each other, and then the gas can be transported through the vent holes on the embedded rings 440 at both ends through the inside of the cover shell 360, and the compressed air is vented to the inside of the adjacent ring bodies 330 and the metal rod 331 by starting the air pump. Flushing allows the compressed air to carry the condensed droplets on the metal rod 331 and discharge them through the inner cavity of the adjacent box body 430 and the water pipe, and the droplets in the ring body 330 connected to the movable tube 310 can be adsorbed to a certain extent by the adsorption plate 431 to reduce the retention of water droplets. The adsorption plate 431 can be made of materials such as sponge, and can have holes for gas to enter and exit. It can adsorb droplets due to its own characteristics. The adsorption plate 431 can be replaced manually. After the compressed air flushing is completed, the movable tube 310 is moved to separate the multiple ring bodies 330 again, and the ring bodies 330 push the adjacent embedded rings 440 to separate naturally, and then the movable cover plate 410 drives the embedded rings 440 to separate from the inside of the cover shell 360.

[0026] Example 2

[0027] On the basis of the first embodiment, the push plate 460 and the moving plate 450 are provided to facilitate the control of the movement of the cover plate 410 and the moving tube 310 .

[0028] like Figure 2 and Figure 10As shown, in this embodiment, two push plates 460 are provided at the inner wall of the cabinet 100, and multiple support rods are fixedly connected to one side of any push plate 460, and any support rod is fixedly connected to the adjacent cover plate 410. The multiple support rods on the two push plates 460 are staggered, and multiple main electric push rods are fixedly connected between any push plate 460 and the inner wall of the cabinet 100, and the movable end of any main electric push rod is fixedly connected to the adjacent push plate 460. Two movable plates 450 are provided on one side of any push plate 460, and multiple snap rings 451 are fixedly connected to any movable plate 450, and any snap ring 451 is fixedly socketed with the adjacent movable tube 310. The multiple snap rings 451 on the two movable plates 450 located on the same push plate 460 are staggered, and a secondary electric push rod is fixedly connected between any movable plate 450 and the inner wall of the adjacent cabinet 100, and the movable end of any secondary electric push rod is fixedly connected to the adjacent movable plate 450.

[0029] During specific implementation, the main electric push rod is started by the controller, and the adjacent push plates 460 and the cover plate 410 can be driven to move by the main electric push rod. The auxiliary electric push rod is started by the controller to drive the adjacent movable plates 450 and the movable tube 310 to move. Since the multiple retaining rings 451 on the two movable plates 450 located on the same side of the push plate 460 are staggered, and the multiple support rods on the two push plates 460 are staggered, the two adjacent separation mechanisms 300 can be controlled to be used staggered by the movement of the movable plates 450 and the push plates 460, thereby continuously cooling the gas for easy use.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
