Description

Technical Field

[0001] The present application belongs to the technical field of processing equipment, and specifically relates to an electrolytic cell. Background Art

[0002] The main body of the electrolytic cell is usually composed of multiple alternately arranged electrode plates and gaskets, and the gaskets can be used to seal the adjacent two electrode plates. During assembly, steam needs to be introduced into the electrolytic cell to heat and soften the gaskets, and then the gaskets need to creep by applying assembly pressure, so that the gaskets fit tightly with the electrode plates to achieve a better sealing effect.

[0003] As the electrolytic cell becomes larger and larger, the main body of the electrolytic cell is usually assembled in an upright state, that is, when the main body of the electrolytic cell is in an upright state, the tension bolts are inserted in sequence, and the two ends are fixed with tension nuts and assembly pressure is applied, and then steam is introduced to soften the gasket and continuously pressurize it to achieve the best sealing state of the electrolytic cell. After the steam is introduced, water vapor will form in the flow channel holes in the electrolytic cell cavity, and then a large amount of water will be generated during internal cooling, which will mainly gather inside the electrolytic cell cavity.

[0004] In the existing technology, during the assembly process of the electrolytic cell, the steam condensate accumulates on the end plate at the bottom of the electrolytic cell and cannot be effectively discharged. After the electrolytic cell is assembled, it contains a large amount of water, which easily causes the electrolytic cell to be too heavy and difficult to lift. Moreover, when the electrolytic cell is assembled and placed horizontally, the water in the electrolytic cell will be discharged from the electrolytic cell, wasting a lot of water resources and causing the workshop production environment to deteriorate. Utility Model Content

[0005] The present application aims to provide an electrolytic cell to solve the problems of the existing electrolytic cell being difficult to lift during assembly, wasting water and easily causing a deterioration in the workshop production environment.

[0007] The present application discloses an electrolytic cell, comprising:

[0008] Two end pressure plates are spaced apart along a first direction; when the electrolytic cell is assembled in a vertical state, the first direction is a vertical direction;

[0009] Two end plates, the two end plates are located between the two end pressure plates, and one end plate is connected to one end pressure plate;

[0010] and a plurality of pole plates and gaskets alternately connected along the first direction, wherein the pole plates and the gaskets are connected between two end pole plates, and the end pole plates and the pole plates are both provided with flow channel holes communicating with each other;

[0011] Wherein, at least one of the end plates is provided with a drainage hole, the drainage hole is communicated with the flow channel hole on the end plate, and the drainage hole is used to discharge the liquid in the flow channel hole.

[0012] Optionally, the electrolytic cell further comprises a plug, and the plug is detachably connected to the drainage hole.

[0013] Optionally, the plug is threadedly connected to the drain hole.

[0014] Optionally, when the electrolytic cell is assembled along the first direction, the end plate located below is a target end plate, and the drainage hole is arranged on a side wall of the target end plate and passes through the side wall.

[0015] Optionally, along the first direction, the lowest point of the hole surface of the drainage hole is lower than the lowest point of the flow channel hole, or the lowest point of the hole surface of the drainage hole is flush with the lowest point of the flow channel hole.

[0016] Optionally, the drainage hole comprises a threaded section and a smooth section that are interconnected, wherein:

[0017] The smooth section is in communication with the flow channel hole, the lowest point of the hole surface of the smooth section is lower than the lowest point of the flow channel hole, or the lowest point of the hole surface of the smooth section is flush with the lowest point of the flow channel hole;

[0018] The threaded section is arranged close to the outer surface of the target end plate, and the lowest point of the hole surface of the threaded section is lower than the lowest point of the hole surface of the smooth section, or the lowest point of the hole surface of the threaded section is flush with the lowest point of the hole surface of the smooth section.

[0019] Optionally, the axis of the threaded segment is aligned with the axis of the smooth segment, and the nominal diameter of the threaded segment is greater than or equal to the inner diameter of the smooth segment.

[0020] Optionally, the inner diameter of the smooth section is in the range of 5 to 30 mm;

[0021] The nominal diameter of the threaded section has a value range of 6-30 mm.

[0022] Optionally, the drainage hole has a depth of 10-45 mm;

[0023] The hole depth of the threaded section ranges from 5 to 35 mm.

[0024] Optionally, the axial direction of the drainage hole is perpendicular to the first direction;

[0025] Alternatively, the axial direction of the drainage hole is inclined relative to the first direction, and one end of the drainage hole is communicated with the flow channel hole, and the other end of the drainage hole extends in an inclined downward direction.

[0026] In an embodiment of the present application, the electrolytic cell can be placed vertically along the first direction for assembly. After steam is introduced into the electrolytic cell and continuously pressurized, the electrolytic cell can reach the required sealing state. Correspondingly, the steam will generate a large amount of water when it cools in the flow channel hole and gather on the end plate at the bottom. The electrolytic cell described in the embodiment of the present application is provided with a drainage hole in the end plate, and the drainage hole can be connected to the flow channel hole on the end plate to discharge the water in the end plate, thereby avoiding the increase in weight caused by the accumulation of water in the electrolytic cell, so as to reduce the difficulty of lifting the electrolytic cell. Moreover, since the water in the electrolytic cell has been discharged through the drainage hole during the assembly process, when the electrolytic cell is placed horizontally after assembly, there is no need to drain the water in the electrolytic cell, thus avoiding the waste of water resources and improving the production environment of the workshop.

[0047] The present application embodiment provides an electrolytic cell, which may include any one of an aqueous solution electrolytic cell, a molten salt electrolytic cell and a non-aqueous solution electrolytic cell. The present application embodiment does not specifically limit the type of the electrolytic cell. Specifically, the electrolytic cell described in the present application embodiment can be assembled in an upright state.

[0048] Reference Figure 1 , showing one of the schematic diagrams of the assembly state of the electrolytic cell described in the embodiment of the present application, referring to Figure 2 , showing the second schematic diagram of the assembly state of the electrolytic cell described in the embodiment of the present application, referring to Figure 3 , showing Figure 2 The schematic diagram of the top view of the electrolytic cell shown in FIG. Figure 4 , showing Figure 2 The partial structural diagram of the electrolytic cell shown in FIG. Figure 5 , showing Figure 4 The schematic diagram of the cross-sectional structure of the electrolytic cell A shown in FIG. Figure 6 , showing Figure 5 A schematic diagram of the partial enlarged structure of the electrolytic cell is shown.

[0049] like Figures 1 to 5As shown, the electrolytic cell may specifically include: two end pressure plates 10 spaced apart along a first direction, and when the electrolytic cell is assembled in a vertical state, the first direction may be a vertical direction; two end plates 11, the two end plates 11 are located between the two end pressure plates 10, and one end plate 11 is connected to one end pressure plate 10; and a plurality of plates 12 and gaskets 13 alternately connected along the first direction, the plates 12 and gaskets 13 are connected between the two end plates 11, and the end plates 11 and the plates 12 are both provided with flow channel holes 100 connected to each other; wherein at least one end plate 11 is provided with a drainage hole 111, the drainage hole 111 is connected to the flow channel hole 100 on the end plate 11, and the drainage hole 111 can be used to discharge the liquid in the flow channel hole 100.

[0050] Specifically, the end pressure plate 10 , the end electrode plate 11 , the electrode plate 12 and the gasket 13 may be stacked along the first direction.

[0051] like Figure 1 As shown, an electrolytic cell assembly device can be used to assemble the electrolytic cell in a vertical state. The electrolytic cell assembly device can specifically include a base 20, a support column 21, an assembly platform 22, and a hoist 23. The support column 21 is connected between the assembly platform 22 and the base 20. The assembly platform 22 can be used to assemble the electrolytic cell, and the hoist 23 can lift the parts of the electrolytic cell.

[0052] To the assembly platform 22.

[0053] In practical applications, one end pressure plate 10 can be placed on the bottom layer, and then a crane 23 can be used to sequentially place an end electrode plate 11, a plurality of alternate gaskets 13 and a plurality of electrode plates 12, and another end electrode plate 11 and an end pressure plate 10 on the end pressure plate 10, so that the electrolytic cell body is in an upright state. Figure 2 As shown, insert the tension bolts 14 in sequence, fix the two ends with tension nuts 15 and apply assembly pressure. Figure 3 High-temperature steam is input into the electrolytic cell at the flange 16 shown, so that the steam flows in the internal cavity of the electrolytic cell. The steam contacts the gasket 13 to soften the gasket 13. After the gasket 13 is softened, continuous pressure is applied to tighten the electrolytic cell, so that the gasket 13 creeps, the cell body of the electrolytic cell is tightened, and the overall optimal sealing state is achieved.

[0054] like Figure 5 As shown, in the sealed assembly of the electrolytic cell, the steam input into the cell body of the electrolytic cell is cooled to form water mist, which gathers in the cell body of the electrolytic cell to form a large amount of water. When the electrolytic cell is in an upright state, the water flows along the flow channel hole 100 in the electrode plate 12 due to gravity. Figure 5The water converges downward in the direction of the vertical arrow in the figure and flows into the end plate 11 at the bottom of the electrolytic cell, and is discharged through the drainage holes 111 on the end plate 11 to recycle the water and avoid water waste.

[0055] In the embodiment of the present application, by setting a drainage hole 111 in the end plate 11, the drainage hole 111 can be connected with the flow channel hole 100 on the end plate 11 to drain the water in the end plate 11, avoid the increase of weight caused by the accumulation of water in the electrolytic cell, and reduce the difficulty of lifting the electrolytic cell. In addition, since the water in the electrolytic cell has been drained through the drainage hole 111 during the assembly process, when the electrolytic cell is placed horizontally after assembly, there is no need to drain the water in the electrolytic cell, so as to avoid the waste of water resources and improve the production environment of the workshop.

[0056] In a specific application, since the end plate 11 of the electrolytic cell is provided with a drainage hole 111, the drainage hole 111 can effectively discharge wastewater and sewage generated during the assembly process, reduce the weight of the electrolytic cell during subsequent transportation, improve the cleanliness of the inside of the electrolytic cell, and reduce the risk of quality problems and shortened service life of the electrolytic cell due to residual sewage inside the electrolytic cell.

[0057] Specifically, the gasket 13 can be made of sealing materials such as rubber and silicone. By arranging the gasket 13 between two adjacent plates 12, the seal between the two plates 12 can be achieved through the thermal creep of the gasket 13. The end plate 11 and the plate 12 are both provided with an electrolysis chamber 112. The electrolysis chamber 112 can be used

[0058] The flow channel hole 100 can be connected to the electrolysis chamber 112. In this way, after the steam is introduced into the electrolysis chamber 112 of each electrode plate 12 through the flange 16 at the top, the steam can flow into the flow channel hole 100 through the electrolysis chamber 112, and finally cool into water through the flow channel hole 100 and gather in the air flow channel of the end electrode plate 11 at the bottom and be discharged through the drainage hole 111.

[0059] In practical applications, the flange 16 can be provided on the end pressure plate 10, and the number of the flanges 16 can be multiple, and the flanges 16 can be used as the inlet and outlet of the electrolyte and the gas. That is, the electrolyte and the gas can enter the electrolytic cell through part of the flanges 16, and correspondingly, the electrolyte or gas after the reaction in the electrolytic cell can be discharged to the outside of the electrolytic cell through another part of the flanges 16.

[0060] Reference Figure 7 , showing Figure 4 The schematic diagram of the structure of the electrolytic cell from another angle is shown in FIG. Figure 8 , showing Figure 7 The schematic diagram of the structure of the electrolytic cell B is shown in FIG. Figure 8 As shown, the electrolytic cell may further include a plug 17 , which is detachably connected to the drain hole 111 .

[0061] In a specific application, during the assembly of the electrolytic cell, the plug 17 does not need to be assembled in the drain hole 111 to avoid blocking the drain hole 111, so that the water in the electrolytic cell can be discharged from the drain hole 111. After the electrolytic cell is assembled, it can be left to stand for several hours to allow the water inside the electrolytic cell to be fully cooled and discharged, and then the plug 17 can be connected to the drain hole 111 to block the drain hole 111, so as to achieve the sealing effect of the end plate 11 through the plug 17. In this way, during the operation of the electrolytic cell, the overall stability and sealing of the electrolytic cell can be improved.

[0062] In some optional embodiments of the present application, the plug 17 can be threadedly connected to the drain hole 111. In this way, it is easy to install and remove the plug 17 in the drain hole 111. At the same time, when the plug 17 is installed in the drain hole 111, a reliable seal for the drain hole 111 can also be achieved.

[0063] Specifically, Figure 8 As shown, the plug 17 may be provided with a thread structure 171. Figure 5 As shown, the drainage hole 111 has a threaded section 1111 , and the threaded structure 171 can be threadedly connected to the threaded section 1111 to achieve a threaded connection between the plug 17 and the drainage hole 111 .

[0064] For example, the plug 17 can be made of a flexible material with a sealing effect, such as rubber or silicone. The embodiment of the present application does not specifically limit the material of the plug 17.

[0065] In a specific application, one of the two terminal plates 10 may be a positive terminal plate, and the other terminal plate 10 may be a negative terminal plate.

[0066] Plate 11 is a positive terminal plate, and the other is a negative terminal plate. The positive terminal plate is connected to the positive terminal pressure plate, and the negative terminal plate is connected to the negative terminal pressure plate.

[0067] like Figure 5As shown, when the electrolytic cell is assembled along the first direction, the end plate 11 located below is the target end plate, and the drainage hole 111 is provided on the side wall of the target end plate and penetrates the side wall to drain the water in the target end plate. In practical applications, by providing the drainage hole 111 on the side wall of the target end plate and making the drainage hole 111 penetrate the side wall, not only can the water in the target end plate be drained from the side of the target end plate, so as to receive the water discharged from the target end plate and avoid water waste. Moreover, it can also prevent the water discharged from the target end plate from affecting the assembly of the parts below the target end plate.

[0068] It should be noted that, in a specific application, when the electrolytic cell places the positive terminal plate at the bottom for assembly, the target terminal plate can be the positive terminal plate, that is, it is only necessary to set the drainage hole 111 on the positive terminal plate. Similarly, when the electrolytic cell places the negative terminal plate at the bottom for assembly, the target terminal plate can be the negative terminal plate, that is, it is only necessary to set the drainage hole 111 on the negative terminal plate. Of course, it is also possible to set the drainage hole 111 on both the positive terminal plate and the negative terminal plate, so that the electrolytic cell can place the positive terminal plate or the negative terminal plate at the bottom according to actual conditions during assembly, thereby improving the assembly flexibility of the electrolytic cell.

[0069] Optionally, along the first direction, the lowest point of the hole surface of the drainage hole 111 is lower than the lowest point of the flow channel hole 100, or the lowest point of the hole surface of the drainage hole 111 is flush with the lowest point of the flow channel hole 100, so that the water in the flow channel hole 100 can fully flow into the drainage hole 111 and be discharged through the drainage hole 111, so as to improve the drainage efficiency of the drainage hole 111.

[0070] It should be noted that Figure 5 and Figure 6 Only the situation that the lowest point of the hole surface of the drainage hole 111 is lower than the lowest point of the flow channel hole 100 is shown. In actual application, the lowest point of the hole surface of the drainage hole 111 can also be flush with the lowest point of the flow channel hole 100.

[0071] like Figure 5 and Figure 6 As shown, the drain hole 111 may include a threaded section 1111 and a smooth section 1112 that are connected to each other, wherein the smooth section 1112 is connected to the flow channel hole 100. Optionally, the lowest point of the hole surface of the smooth section 1112 is lower than the lowest point of the flow channel hole 100, or the lowest point of the hole surface of the smooth section 1112 is flush with the lowest point of the flow channel hole 100, so that the water in the flow channel hole 100 can fully flow into the smooth section 1112; the threaded section 1111

[0072] It is arranged close to the outer surface of the target end plate 11, and the lowest point of the hole surface of the threaded segment 1111 is lower than the lowest point of the hole surface of the smooth segment 1112, or the lowest point of the hole surface of the threaded segment 1111 is flush with the lowest point of the hole surface of the smooth segment 1112, so that the water in the smooth segment 1112 can fully flow into the threaded segment 1111 and be discharged through the threaded segment 1111, so as to improve the drainage efficiency of the drainage hole 111.

[0073] In practical applications, the threaded section 1111 can be used to connect with the plug 17, while the smooth section 1112 has the advantages of easy processing, sufficient drainage and not easy to leave residue. Therefore, by setting the drainage hole 111 to be a threaded section 1111 and a smooth section 1112 that are interconnected, it is easy to connect with the plug 17, easy to process, and conducive to drainage.

[0074] It should be noted that Figure 5 and Figure 6 Only the case where the drain hole 111 includes a threaded section 1111 and a smooth section 1112 that are interconnected is shown. In practical applications, the drain hole 111 can be configured as a threaded section 1111 or as a smooth section 1112. When the drain hole 111 is configured as a smooth section 1112, the plug 17 and the drain hole 111 can be interference-fitted to achieve reliable sealing of the plug 17 for the drain hole 111. The embodiment of the present application does not specifically limit the configuration of the drain hole 111.

[0075] and, Figure 5 and Figure 6 It is only shown that the lowest point of the hole surface of the smooth section 1112 is lower than the lowest point of the flow channel hole 100, and the lowest point of the hole surface of the threaded section 1111 is lower than the lowest point of the hole surface of the smooth section 1112. In actual applications, the lowest point of the hole surface of the smooth section 1112 can also be flush with the lowest point of the flow channel hole 100, and the lowest point of the hole surface of the threaded section 1111 can also be flush with the lowest point of the hole surface of the smooth section 1112.

[0076] like Figure 5 and Figure 6As shown, the axis of the threaded segment 1111 is aligned with the axis of the smooth segment 1112, and the nominal diameter of the threaded segment 1111 is greater than or equal to the inner diameter of the smooth segment 1112. In a specific application, when the axis of the threaded segment 1111 is aligned with the smooth segment 1112, and the nominal diameter of the threaded segment 1111 is greater than or equal to the inner diameter of the smooth segment 1112, the drainage hole 111 can be first processed into an integral smooth hole by a drilling process. Then, on the basis of the smooth hole, an internal thread is processed in the smooth hole by a tapping process to form the threaded segment 1111, and the processing method is relatively simple. Moreover, when the axis of the threaded segment 1111 is aligned with the axis of the smooth segment 1112, the space occupied by the drainage hole 111 on the end plate 11 is correspondingly smaller, and the impact on the overall strength of the end plate 11 is also smaller.

[0077] It should be noted that the drawings of the embodiments of the present application only show a scheme in which the axis of the threaded segment 1111 is aligned with the axis of the smooth segment 1112. In actual applications, the axis of the threaded segment 1111 and the axis of the smooth segment 1112 can also be set to be non-aligned, that is, the threaded segment 1111 and the smooth segment 1112 are distributed in a stepped hole shape. The embodiments of the present application do not make specific limitations on the relative position relationship between the threaded segment 1111 and the smooth segment 1112.

[0078] like Figure 6 As shown, the inner diameter of the smooth section 1112 can be represented by D2, and the value range of D2 is: 5-30 mm; the nominal diameter of the threaded section 1111 can be represented by D1, and the value range of D1 is: 6-30 mm. In a specific application, when the value of D2 is less than 5 mm, the inner diameter of the smooth section 1112 is too small, which is not conducive to the discharge of water. In the case where the value of D2 is greater than 30 mm, the inner diameter of the smooth section 1112 is too large, which may cause the drainage hole 111 to occupy a larger space as a whole, which is not conducive to the structural stability of the end plate 11. By limiting the value of D1 to 6-30 mm, the nominal diameter of the threaded section 1111 can be better adapted to the inner diameter of the smooth section 1112, so as to reduce the tapping workload of the threaded section 1111 and improve the processing efficiency of the threaded section 1111.

[0079] For example, the value range of D2 can also be 6-29 mm, 8-27 mm, 9-26 mm, 11-25 mm, 12-22 mm, and 13-15 mm, etc., and those skilled in the art can set the value of D2 to any one of 5 mm, 7 mm, 10 mm, 16 mm, and 28 mm according to actual needs. Similarly, correspondingly, the value range of D1 can also be 7-28 mm, 9-27 mm, 10-26 mm, 12-25 mm, 13-22 mm, and 14-18 mm, etc., and those skilled in the art can set the value of D1 to 6 mm, 8 mm, 11 mm, 17 mm, and 29 mm according to actual needs. The embodiment of the present application does not specifically limit the values ​​of D1 and D2.

[0080] like Figure 6 As shown, the hole depth of the drain hole 111 can be represented by L2, and the value of L2 can be 10-45 mm; the hole depth of the threaded section 1111 can be represented by L1, and the value range of L1 can be 5-35 mm. In specific applications, the value range of L2 can be related to the straight-line distance between the flow channel hole 100 and the outer surface of the end plate 11. Generally, the shorter the straight-line distance between the flow channel hole 100 and the outer surface of the end plate 11, the shorter the distance from the outer surface of the end plate 11 to the flow channel hole 100, and accordingly, the smaller the value of L2. Usually, when the value of L2 is less than 10 mm, it is difficult for the drain hole 111 to penetrate into the flow channel hole 100. When the value of L2 is greater than 45 mm, the depth of the drain hole 111 penetrating into the flow channel hole 100 is deeper, which has a greater impact on the overall structure of the end plate 11.

[0081] Specifically, the hole depth L1 of the threaded segment 1111 can be set according to actual conditions to achieve plugging.

[0082] Generally, when the value of L1 is less than 5 mm, the meshing distance between the plug 17 and the threaded segment 1111 is short, and it is difficult for the plug 17 to achieve a reliable seal for the threaded segment 1111. When the value of L1 is greater than 35 mm, it is not conducive to the operation of screwing the plug 17 into the threaded segment 1111, and the processing difficulty of the threaded segment 1111 is also relatively large.

[0083] For example, the value range of L2 can also be 11-44 mm, 12-42 mm, 13-40 mm, 15-38 mm or 20-30 mm, etc., and those skilled in the art can determine the value of L2 to any one of 10 mm, 18 mm, 27 mm, 34 mm and 45 mm according to actual needs. Correspondingly, the value range of L1 can be 6-34 mm, 8-32 mm, 11-30 mm, 12-28 mm or 15-25 mm, etc., and those skilled in the art can determine the value of L1 to any one of 5 mm, 10 mm, 13 mm, 22 mm and 35 mm according to actual needs. The embodiment of the present application does not specifically limit the values ​​of L2 and L1.

[0084] like Figure 5 and Figure 6 As shown, the axial direction of the drainage hole 111 is perpendicular to the first direction, which is not only beneficial to the processing of the drainage hole 111, but also the hole depth of the drainage hole 111 in the end plate 11 is minimal, which has little effect on the strength of the end plate 11, and is beneficial to improving the structural stability of the end plate 11.

[0085] Optionally, the axial direction of the drain hole 111 may be inclined relative to the first direction, and one end of the drain hole 111 is connected to the flow channel hole 100, and the other end of the drain hole 111 extends in an inclined downward direction. In this way, once the water in the flow channel hole 100 is discharged to the drain hole 111, the drain hole 111 can quickly drain the water, reducing the residual water in the drain hole 111, thereby improving the drainage efficiency of the drain hole 111 and shortening the static drainage time of the electrolytic cell during the assembly process.

[0086] It should be noted that, in the drawings of the embodiments of the present application, only the case where the axial direction of the drainage hole 111 is perpendicular to the first direction is shown. In actual applications, those skilled in the art may also set the axial direction of the drainage hole 111 to be tilted downward relative to the first direction according to actual needs, and the downward tilt angle may include but is not limited to any one of 5 degrees, 8 degrees, 9 degrees, 12 degrees and 15 degrees. The embodiments of the present application do not specifically limit the axial downward tilt angle of the drainage hole 111.

[0087] Reference Fig. 9 , showing a schematic diagram of the structure of an end plate according to an embodiment of the present application, referring to Fig.10 , showing Fig. 9 The cross-sectional structure diagram of the end plate CC direction shown in FIG. Fig.11 , showing Fig. 9 The schematic diagram of the structure of the end plate D direction shown in FIG. Fig.12 , showing Fig. 9 The terminal plate E shown

[0088] The enlarged structural diagram of the position. Fig. 9 As shown, the end plate 11 may be provided with a plurality of electrolytic chambers 112 and flow holes 100. During the assembly process of the electrolytic cell, steam may enter the electrolytic chamber 112 and flow into the flow holes 100 through the electrolytic chamber 112. The number of the flow holes 100 may be multiple, and the multiple flow holes 100 may be distributed along the circumference of the end plate 11. Fig. 9 As shown, two flow channel holes 100 may be selected to provide drainage holes 111 communicating therewith.

[0089] It should be noted that, in actual applications, the number of drainage holes 111 can be set according to actual conditions. For example, the drainage hole 111 can be set only on the side wall of one flow channel hole 100. For another example, a drainage hole 111 can be set on each side wall of the flow channel hole 100. For another example, a flow channel hole can be set on each side wall of 2, 3, 4, 6 or 8 flow channel holes 100 in a plurality of air corridor holes, and the embodiments of the present application are not limited to this.

[0090] In summary, the electrolytic cell described in the embodiment of the present application may at least include the following advantages:

[0091] In an embodiment of the present application, the electrolytic cell can be placed vertically along the first direction for assembly. After steam is introduced into the electrolytic cell and continuously pressurized, the electrolytic cell can reach the required sealing state. Correspondingly, the steam will generate a large amount of water when it cools in the flow channel hole and gather on the end plate at the bottom. The electrolytic cell described in the embodiment of the present application is provided with a drainage hole in the end plate, and the drainage hole can be connected to the flow channel hole on the end plate to discharge the water in the end plate, thereby avoiding the increase in weight caused by the accumulation of water in the electrolytic cell, so as to reduce the difficulty of lifting the electrolytic cell. Moreover, since the water in the electrolytic cell has been discharged through the drainage hole during the assembly process, when the electrolytic cell is placed horizontally after assembly, there is no need to drain the water in the electrolytic cell, thus avoiding the waste of water resources and improving the production environment of the workshop.
