Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production equipment, and in particular to an electrolytic cell support device and an electrolytic cell. Background Art

[0002] In the hydrogen energy industry, the industry chain is mainly divided into hydrogen production, hydrogen storage, hydrogen transportation, hydrogenation and hydrogen use, and the technical routes of hydrogen production are divided into four types: alkaline water electrolysis hydrogen production, PEM water electrolysis hydrogen production, anion exchange membrane electrolysis hydrogen production, and solid oxide water electrolysis hydrogen production. Among them, alkaline water electrolysis hydrogen production is relatively mature, and alkaline water electrolysis hydrogen production devices can be divided into power supply and control system, electrolyzer system, separation and purification system and auxiliary system according to function.

[0003] At present, circular electrolyzers generally adopt a tensioned structure with a tie rod. The disc springs on both sides of the tie rod will give the pressure plates on both sides an extrusion force pointing to the center. The components in the pressure plate rely on the static friction formed by the pressure to maintain their vertical position without sliding down. When the circular electrolyzer reaches the rated operating condition, the operating temperature in the tank is generally maintained at 90±5℃. Under this condition, the sealing gasket between the bipolar plates will creep due to the high temperature, which will reduce the friction coefficient between the sealing gasket and the bipolar plate, while the extrusion force between the two pressure plates remains unchanged, and the friction between the components in the pressure plate is reduced, and the bipolar plate falls due to insufficient friction. However, the falling of the bipolar plate will cause the flow field of the electrolysis chamber to change. Severe falling will cause hydrogen leakage in the electrolyzer, which will cause explosion risk or electrolyzer shutdown.

[0040] Combine the following Figure 1-Figure 13 An electrolytic cell supporting device according to an embodiment of the present invention is described.

[0041] The embodiment of the present invention provides an electrolytic cell support device, such as Figure 1 As shown, the electrolytic cell support device includes at least one support assembly 100, the support assembly 100 includes a first support seat 110, the first support seat 110 includes two half supports 111 arranged opposite to each other, the lower parts of the two half supports 111 are detachably connected, the two half supports 111 enclose a accommodating space 112 adapted to the bottom of the electrolytic cell 400, and the upper parts of the two half supports 111 are both provided with insulating supports 120, and the insulating supports 120 are suitable for abutting against the electrolytic cell 400.

[0042] It can be understood that the electrolytic cell 400 adopts the method of raising the pressure plates 410 at both ends, but the first support seat 110 has a certain height, the installation space at the bottom of the electrolytic cell 400 is limited, and the existence of the long pull rod of the electrolytic cell 400 will also hinder the installation of the first support seat 110. Therefore, in this embodiment, the first support seat 110 is designed as a two-half structure. Specifically, the first support seat 110 includes two half supports 111 arranged opposite to each other, and the lower parts of the two half supports 111 are detachably connected. There is a distance between the upper parts of the two half supports 111, so that the two half supports 111 are connected to form a accommodating space 112 that is compatible with the bottom of the electrolytic cell 400, and an insulating support 120 is arranged on the upper part of the half support 111, and the insulating support 120 is pressed against the bipolar plate of the electrolytic cell 400 to provide support for the bipolar plate of the electrolytic cell 400.

[0043] The electrolytic cell support device provided in the embodiment of the present invention is provided with a support assembly 100 at the bottom of the electrolytic cell 400, and the first support seat 110 of the support assembly 100 is provided with an insulating support member 120 that abuts against the electrolytic cell 400, so as to provide effective support for the bipolar plates of the electrolytic cell 400 and prevent the bipolar plates from falling; and the first support seat 110 is designed as two half-supports 111 arranged opposite to each other, so as to facilitate the assembly of the first support seat 110 at the bottom of the electrolytic cell 400.

[0044] According to an embodiment of the present invention, Figure 1 As shown, the half support 111 is L-shaped, and one side edge of the half support 111 is arranged in the horizontal direction to serve as the lower part of the half support 111. The lower parts of the two half supports 111 are connected by flanges.

[0045] Optionally, for electrical safety, the bottom of the first support seat 110 is insulated, and an insulating pad 150 can be connected to the bottom of the first support seat 110. Specifically, the bottom of the semi-support 111 is connected to the support seat bottom plate 140, threaded holes are opened on the insulating pad 150, and the threaded holes of the support seat bottom plate 140 and the insulating pad 150 are connected by bolts to achieve the connection between the support seat bottom plate 140 and the insulating pad 150, and ensure that the bottom of the bolts retains a sufficient electrical disconnection distance from the ground.

[0046] Furthermore, the distance between the insulating support members 120 on the two half supports 111 decreases from bottom to top, so that the insulating support members 120 are arranged at an angle to better support the electrode plates of the electrolytic cell 400 .

[0047] In one embodiment of the present invention, Figures 1 to 4 As shown, the surface of the insulating support 120 away from the half support 111 has a positioning surface 121 adapted to the electrolytic cell 400 .

[0048] It can be understood that the insulating support member 120 is a structural member in contact with the bipolar plate. When the electrolytic cell 400 is working normally, the bipolar plate is charged. In order to prevent the insulating support member 120 from causing a short circuit between the two bipolar plates, the insulating support member 120 in contact with the bipolar plate is insulated. The top surface of the support member is the surface in contact with the bipolar plate. In order to ensure good contact between the support member and the bipolar plate, the shape of the top surface of the support member matches the outer side surface of the bipolar plate. If the electrolytic cell 400 is a circular electrolytic cell, the surface of the insulating support member 120 away from the half support 111 is an arc surface that is consistent with the circular electrolytic cell quota.

[0049] Furthermore, a receiving groove 122 is formed on a surface of the insulating support 120 away from the half support 111 , and the receiving groove 122 is used to receive a gasket of the electrolytic cell 400 .

[0050] It is understandable that during the hot screwing process, the sealing gaskets between the bipolar plates are often squeezed out. Therefore, a receiving groove 122 is designed on the insulating support 120, and the receiving groove 122 is used to accommodate the gasket of the electrolytic cell 400; so that when the insulating support 120 supports the bipolar plate, the squeezed gasket falls into the receiving groove 122 of the insulating support 120, and the insulating support 120 can be designed as a multi-point support form.

[0051] In one embodiment of the present invention, Figure 1 As shown, the support assembly 100 further includes a first adjustment component 130 disposed between the half support 111 and the insulating support 120 , and the first adjustment component 130 is used to adjust the height of the insulating support 120 .

[0052] Optionally, the first adjustment component 130 includes a pushing screw 131 and a locking piece 132, the first end of the pushing screw 131 is connected to the insulating support 120, and the second end of the pushing screw 131 is passed through the upper part of the semi-support 111; two locking pieces 132 are arranged on the pushing screw 131, and respectively abut against the opposite sides of the upper part of the semi-support 111.

[0053] Specifically, the top of the half support 111 has a horizontal plate, and each horizontal plate of the half support 111 is provided with a first connection hole, which can be a through hole or a threaded hole; the insulating support 120 is provided with a second connection hole, which is generally a through hole; the bottom end of the push screw 131 passes through the first connection hole, and a locking member 132 is screwed on each side of the push screw 131 passing through the horizontal plate. The locking member 132 can be a nut with a multiple anti-loosening design, and the top of the push screw 131 is inserted into the second connection hole, so that the insulating support 120 is pressed against the bipolar plate of the electrolytic cell 400. It should be noted here that in actual operation, the height of the insulating support 120 in the vertical direction can be controlled by screwing the push screw 131.

[0054] In another embodiment of the present invention, Figure 7 As shown, the insulating support 120 is designed as a columnar structure, and the insulating support 120 includes an insulating roller arranged in a horizontal direction, and a groove for placing the insulating roller is provided on the upper part of the half support 111, and a receiving groove 122 is opened on the surface of the insulating roller, and the receiving groove 122 is used to accommodate the gasket of the electrolytic cell 400.

[0055] It should be noted that the insulating support 120 can be designed as a long columnar structure corresponding to the length of the electrolytic cell 400. Further, considering that there are multiple bipolar plates with different sliding degrees, and the first support seat 110 has manufacturing accuracy problems, the long columnar structure can be changed into a multi-section short columnar structure with the same diameter specification, and the multi-section short columnar structure is arranged on a plurality of first support seats 110. In this way, the electrolytic cell support device of this embodiment includes a plurality of support assemblies 100, each of which includes a first support seat 110 and an insulating roller (i.e., a short columnar structure) disposed on the first support seat 110.

[0056] In an optional embodiment of the present invention, Figure 7 As shown, the support assembly 100 also includes a second support base 160 located below the first support base 110 . The first support base 110 is connected to the second support base 160 via a second adjustment component, and the second adjustment component is used to adjust the height of the first support base 110 .

[0057] It can be understood that the second adjusting component can adopt the same structure as the first adjusting component 130, and multiple second adjusting components are arranged between the first support seat 110 and the second support seat 160, for example, including four second adjusting components arranged in a rectangular shape, and the installation height of the first support seat 110 is adjusted by the second adjusting component, and then the height of the insulating support 120 is adjusted so that the insulating support 120 is pressed against the bipolar plate of the electrolytic cell 400.

[0058] It should be noted that the height of the insulating support 120 can be adjusted by setting a first adjustment component 130 between the half support 111 and the insulating support 120, see Figure 1 The height of the insulating support member 120 can also be adjusted by a second adjustment member between the first support seat 110 and the second support seat 160, see Figure 7 Of course, a first adjustment component 130 may be provided between the half support 111 and the insulating support 120, and a second adjustment component may be provided between the first support seat 110 and the second support seat 160.

[0059] It should be noted that the second adjustment component can also adopt an adjustment screw. The first support seat 110 and the second support seat 160 are matched with inclined surfaces. The second support seat 160 has a screw fixing plate. The adjustment screw is connected to the screw fixing plate and abuts against the first support seat 110. By rotating the adjustment screw, the first support seat 110 is pushed to slide upward on the second support seat 160, and then the insulating support member 120 slides upward until it hits the bipolar plate.

[0060] In one embodiment of the present invention, Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the support assembly 100 includes a plurality of support components 100 arranged side by side.

[0061] Optionally, the electrolytic cell 400 is a circular electrolytic cell. The electrolytic cell support device of this embodiment includes 5 to 10 support components 100 arranged at the bottom of the circular electrolytic cell to ensure that there are sufficient support points, thereby providing effective support for the bipolar plates of the electrolytic cell 400.

[0062] Further, such as Figure 2 , Figure 4 and Figure 6 As shown, a plurality of support assemblies 100 are connected by a connecting beam 300, and the connecting beam 300 is used to connect a plurality of support bases into a whole for easy transportation.

[0063] Optionally, all support assemblies 100 may be connected into a whole through the connecting beam 300, or some of the support assemblies 100 may be connected into a whole through the connecting beam 300. For example, the electrolytic cell support device includes 9 support assemblies 100, the 9 support assemblies 100 are arranged at intervals, and the 9 support assemblies 100 may be connected into a whole through two parallel connecting beams 300, or every three support assemblies 100 may be connected into a whole through two parallel connecting beams 300, and every three support assemblies 100 and the connecting beam 300 may be used as a support unit, then the electrolytic cell support device includes three support units arranged side by side, and each support unit includes three support assemblies 100 arranged side by side and connected by the connecting beam 300. It should be noted here that in other embodiments, the number of support assemblies 100 in different support units may be equal or unequal.

[0064] In one embodiment of the present invention, for a short circular electrolytic cell, the length of this type of electrolytic cell 400 is relatively short, the temperature distribution of the internal flow field is relatively uniform, and the thermal creep of the gasket will not cause excessive deformation of the bipolar plate in the horizontal direction. Therefore, the support of the support assembly 100 of the above embodiment is sufficient to meet the working condition requirements. For a large square circular electrolytic cell, the number of electrolytic chambers is large, the length of the electrolytic cell 400 is relatively long, and the internal temperature of the electrolytic cell 400 is more unevenly distributed in the length direction. The thermal creep of the gasket will cause the spacing between the two pressure plates 410 to change, that is, the bipolar plate will produce a horizontal displacement. To adapt to this working condition, the present embodiment sets a sliding mechanism 170 at the bottom of the support assembly 100 so that the support assembly 100 has the ability to move in the horizontal direction.

[0065] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, when the support assembly 100 includes the first support seat 110, a sliding mechanism 170 is provided at the bottom of the first support seat 110, and the sliding mechanism 170 is suitable for driving the first support seat 110 to move along the length direction of the electrolytic cell 400. It should be noted here that for the support unit, a sliding mechanism 170 is provided below each support assembly 100 of the support unit.

[0066] Optionally, the sliding mechanism 170 may adopt a wheel set structure, which includes a supporting wheel arranged at the lower part of each half support 111, and baffles are arranged at both ends of the supporting wheel to prevent slippage.

[0067] like Figure 7 As shown, when the support assembly 100 includes a first support seat 110 and a second support seat 160 , a sliding mechanism 170 is provided at the bottom of the second support seat 160 , and the sliding mechanism 170 is suitable for driving the second support seat 160 to move along the length direction of the electrolytic cell 400 .

[0068] For the electrolytic cell 400 with a large square and long total length of the electrolytic chamber, the downward movement in the center of the cell body will be more obvious. In order to improve the reliability of the bottom support, the number of bottom support points (i.e., support assembly 100) can be increased, and the length of the insulating support 120 can be lengthened.

[0069] The first support seat 110 and the second support seat 160 make the support assembly 100 a two-layer support structure. The insulating support member 120 is placed on the top of the first support seat 110, and the second support seat 160 is provided with 4 wheel group structures. The lower end of the adjustment screw (i.e., the push screw 131) is screwed into the threaded hole of the second support seat 160, and the upper end passes through the through hole of the first support seat 110. The first support seat 110 falls on the nut of the adjustment screw. Two nuts are provided here to form a double nut anti-loosening. During adjustment, the height of the nut in the vertical direction is adjusted, and then the height dimension of the first support seat 110 is adjusted, so that the insulating support member 120 is supported to the bottom of the bipolar plate. Preferably, the push screw 131 of the second adjustment component is replaced with an adjustment bolt.

[0070] In one embodiment of the present invention, Figure 8 and Fig. 9 As shown, the electrolytic cell support device also includes a support beam 200, and all support components 100 are arranged on the support beam 200, which provides smooth sliding of the support components 100 along the length direction of the electrolytic cell 400, while reducing the requirements on the ground at the installation site.

[0071] Further, such as Fig. 9 As shown, the support beam 200 is provided with two edge-covered through holes, which serve as forklift holes 220 for transporting the support beam 200 .

[0072] In one embodiment of the present invention, Figures 8 to 13 As shown, support components 210 are provided at both ends of the support beam 200 to cooperate with the bottoms of the pressure plates 410 at both ends of the electrolytic cell 400 .

[0073] It can be understood that support components 210 are provided at both ends of the support beam 200, and the pressure plates 410 at both ends of the electrolytic cell 400 are arranged on the support components 210 at both ends of the support beam 200. At the same time, there is a distance between the bipolar plate of the electrolytic cell 400 and the support beam 200, which facilitates the installation of the support assembly 100 at the bottom of the electrolytic cell 400.

[0074] Optional, such as Figure 8 and Fig. 9 As shown, the support component 210 is an arc-shaped plate supported at the end of the support beam 200, on which an arc-shaped insulating plate is arranged, and the arc-shaped insulating plate matches the bottom structure of the pressure plate 410 at the end of the electrolytic cell 400. In actual use, the support beam 200 and the pressure plate 410 at the end of the electrolytic cell 400 are connected together to ensure that when the electrolytic cell 400 is hoisted, the support beam 200 and the support assembly 100 on the support beam 200 remain integrated with the electrolytic cell 400.

[0075] Optional, such as Figures 10 to 13As shown, the support component 210 includes two L-shaped connecting plates arranged opposite to each other, the L-shaped connecting plates include a first plate body and a second plate body vertically connected, the second plate bodies of the two L-shaped connecting plates are connected to the end of the support beam 200 through a third connecting component, the first plate bodies of the two L-shaped connecting plates are arranged at a relative interval, and a receiving groove for receiving the pressure plate 410 is formed between the two first plate bodies.

[0076] The third connecting component includes a bolt 215 and a nut 211. The bolt 215 passes through the insulating washer 213, the end of the support beam 200 and the second plate in sequence and is connected to the nut 211. An insulating sleeve 214 is sleeved on the bolt 215. An insulating washer 213 is also provided between the second plate and the nut 211, and a spring washer 212 is provided between the insulating washer 213 and the nut 211. An insulating plate is provided between the end of the support beam 200 and the second plate of the two L-shaped connecting plates to achieve electrical insulation between the pressing plate 410 and the support beam 200. The support beam 200 can effectively reduce the torsional deformation of the electrolytic cell 400 during the hoisting process and improve the rigidity of the main body of the electrolytic cell 400.

[0077] The pressure plate 410 of the electrolytic cell 400 is arranged between the first plate bodies of the two L-shaped connecting plates. The pressure plate 410 and the first plate body can also be connected and fixed by a third connecting component. Insulating washers 213 are respectively arranged on both sides of the bolt 215, and an insulating sleeve is arranged on the outer circle of the bolt 215.
