Description

Technical Field

[0001] This application relates to the field of water electrolysis hydrogen production technology, and in particular to an electrode channel support device. Background Technology

[0002] The core component of hydrogen production through water electrolysis is the electrolyzer, which is typically a bipolar pressure filter type. This type consists of multiple electrode plates stacked together, sealed and insulated from each other by gaskets. Several holes are drilled in each electrode plate and gasket to allow the flow of alkali solution and gas.

[0003] For pressure-type electrolytic cells, sufficient pre-tightening force must be applied to both ends to ensure effective sealing. The temperature and pressure differences between standby and operating conditions are significant, making the gaskets prone to deformation and intrusion into the channels. When the gaskets enter the channels, they can block the flow of liquid and gas, causing the electrolytic cell to experience gas trapping, insufficient liquid supply, and impurity accumulation. This leads to problems such as increased energy consumption, decreased gas purity, abnormal temperature rise, and electrode corrosion. Utility Model Content

[0004] To reduce the probability of gasket blockage in the channel, this application provides an electrode channel support device.

[0005] The electrode plate channel support device provided in this application adopts the following technical solution:

[0006] An electrode plate channel support device includes an electrode plate with a plurality of channels evenly distributed around its circumference. A gasket is attached to one side of the electrode plate, and a through hole is formed on the gasket corresponding to the position of the electrode plate channel. The through hole connects to the channel, and a support ring is inserted into the channel. One end of the support ring is inserted into the channel, and the other end is inserted into the corresponding through hole.

[0007] By adopting the above technical solution, the gasket used for sealing is supported by the support ring, reducing the probability of the gasket clogging the channel. This reduces the probability of the gasket entering the channel and causing blockage of liquid and gas flow, resulting in gas trapping, insufficient liquid supply, and impurity accumulation in the electrolytic cell, which can lead to increased energy consumption, decreased gas purity, abnormal temperature rise, and electrode corrosion.

[0008] Optionally, a receiving ring plate is fixedly provided on the inner wall of the channel, and one end of the support ring inserted into the channel abuts against the receiving ring plate.

[0009] By adopting the above technical solution, the setting of the receiving ring plate can provide a positioning point for the support ring, thereby reducing the probability of over-insertion of the support ring.

[0010] Optionally, the support ring has flow guide ports on both sides in the thickness direction, the electrode plate has a groove in the center, and the electrode plate has a connection port. The connection port connects the groove and the channel. When the support ring is inserted and installed on the electrode plate, the flow guide port is located between the connection port and the channel and connects the groove and the channel.

[0011] By adopting the above technical solution, the guide port, in conjunction with the groove and the connection port, can provide a temporary channel for liquid and gas to flow when the channel is blocked. This reduces the probability of problems such as gas blockage, insufficient liquid supply, and impurity accumulation in the electrolytic cell caused by channel blockage, which can lead to increased energy consumption, decreased gas purity, abnormal temperature rise, and electrode corrosion in the electrolytic cell.

[0012] Optionally, the channel includes a circular hole and an oblong hole, and the support ring includes a circular ring and an oblong ring, wherein the circular ring is inserted into the circular hole and the oblong ring is inserted into the oblong hole.

[0013] By adopting the above technical solution, round holes and oblong holes are the commonly used shapes on the uniform electrode plate. According to actual needs, round holes and oblong holes can be opened to meet different requirements.

[0014] Optionally, the electrode plate has a positioning groove in the circumferential direction of the circular hole, and a positioning block is fixed on the ring.

[0015] By adopting the above technical solution, the positioning groove and positioning block can cooperate to position the ring, reducing the probability that the rotation of the ring will cause the guide port to rotate and fail to connect the connection port.

[0016] Optionally, a reinforcing rib is fixed inside the waist-shaped ring, and the reinforcing rib is fixed in the middle of the waist-shaped ring.

[0017] By adopting the above technical solution, the waist-shaped ring is relatively long and prone to breakage in the middle. The addition of reinforcing ribs can improve the structural strength of the waist-shaped ring and reduce the probability of breakage.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] By supporting the gasket used for sealing with a support ring, the probability of the gasket clogging the channel is reduced, thereby reducing the probability of blockage of liquid and gas flow caused by the gasket entering the channel, which can lead to problems such as gas trapping, insufficient liquid supply and impurity accumulation in the electrolytic cell, resulting in increased energy consumption, decreased gas purity, abnormal temperature rise and electrode corrosion.

[0020] The guide port, in conjunction with the groove and connection port, can provide a temporary channel for liquid and gas flow when the channel is blocked, reducing the probability of problems such as gas blockage, insufficient liquid supply and impurity accumulation in the electrolytic cell caused by channel blockage, which can lead to increased energy consumption, decreased gas purity, abnormal temperature rise and electrode corrosion in the electrolytic cell.

[0021] Round holes and oblong holes are commonly used shapes on uniform electrode plates. Round holes and oblong holes can be made according to actual needs to meet different requirements. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] This application discloses an electrode plate channel support device, referring to... Figure 1The system includes a circular electrode plate 1 with a plurality of channels 2 evenly distributed around its circumference. The channels 2 are located near the edge of the electrode plate 1. A gasket 3 is attached to one side of the electrode plate 1. In this embodiment, the gasket 3 is made of a material with sufficient strength and good insulation, such as polysulfone, ceramic, PA plastic, etc., and is manufactured using machining, injection molding, sintering and other processes. A through hole 4 is opened on the gasket 3 corresponding to the channel 2 of the electrode plate 1. The through hole 4 connects to the channel 2. A support ring 5 is inserted into the channel 2. One end of the support ring 5 is inserted into the channel 2 and the other end is inserted into the corresponding through hole 4. The support ring 5 supports the gasket 3 for sealing, reducing the probability of the gasket 3 blocking the channel 2. This reduces the probability of the gasket 3 blocking the flow of liquid and gas due to the gasket 3 entering the channel 2, causing problems such as gas blockage, insufficient liquid supply and impurity accumulation in the electrolytic cell, which can lead to increased energy consumption, decreased gas purity, abnormal temperature rise and corrosion of the electrode plate 1.

[0029] Reference Figure 1 and Figure 2 A receiving ring plate 6 is integrally fixed on the inner wall of the channel 2. One end of the support ring 5 is inserted into the channel 2 and abuts against the receiving ring plate 6. The receiving ring plate 6 is located in the middle of the channel 2. Both sides of the receiving ring plate 6 can be used to abut against the support ring 5. The support ring 5 can be inserted on both sides of the electrode plate 1. Gaskets 3 can be set on both sides of the electrode plate 1.

[0030] Reference Figure 2 and Figure 3 The support ring 5 has flow guide ports 12 on both sides in the thickness direction, the electrode plate 1 has a groove 7 in the center, and the electrode plate 1 has a connection port 8. The connection port 8 connects the groove 7 and the channel 2. When the support ring 5 is inserted and installed on the electrode plate 1, the flow guide port 12 is located between the connection port 8 and the channel 2 and connects the groove 7 and the channel 2. The flow guide port 12, in conjunction with the groove 7 and the connection port 8, can provide a temporary channel for liquid and gas to flow when the channel 2 is blocked. This reduces the probability of problems such as gas blockage, insufficient liquid supply and impurity accumulation in the electrolytic cell caused by the blockage of the channel 2, which would lead to increased energy consumption, decreased gas purity, abnormal temperature rise and corrosion of the electrode plate 1.

[0031] Reference Figure 2 and Figure 3The channel 2 includes a circular hole 21 and an oblong hole 22. The support ring 5 includes a circular ring 51 and an oblong ring 52. The circular ring 51 is inserted into the circular hole 21, and the oblong ring 52 is inserted into the oblong hole 22. The circular hole 21 and the oblong hole 22 are the common shapes used on the electrode plate 1. The circular hole 21 and the oblong hole 22 can be opened according to actual needs to meet different requirements. The electrode plate 1 has a positioning groove 9 circumferentially opened in the circular hole 21. A positioning block 10 is fixed on the circular ring 51. The positioning groove 9 and the positioning block 10 cooperate to position the circular ring 51, reducing the probability that the rotation of the circular ring 51 will cause the guide port 12 to rotate and fail to connect the connection port 8. A reinforcing rib 11 is fixed in the oblong ring 52. The reinforcing rib 11 is fixed in the middle of the oblong ring 52. The oblong ring 52 is relatively long and the middle part is prone to breakage. The setting of the reinforcing rib 11 can improve the structural strength of the oblong ring and reduce the probability of the oblong ring 52 breaking.

[0032] The implementation principle of this application embodiment is as follows: A corresponding support ring 5 is inserted into the channel 2 on the electrode plate 1, so that the guide port 12 at one end of the support ring 5 inserted into the channel 2 is aligned with the connection port 8, thereby connecting the channel 2 and the groove 7. Then, the gasket 3 is installed on the electrode plate 1. After the gasket 3 is installed, the side of the gasket 3 away from the electrode plate 1 is flush with the bottom of the guide port 12 at the side of the support ring 5 away from the electrode plate 1. Subsequently, by installing another electrode plate 1, the support ring 5 is inserted into the other electrode plate 1 at the side away from the first electrode plate 1, thus completing the installation between the two electrode plates 1. Through the reciprocating assembly of the electrode plate 1 and the gasket 3, the installation of the electrolytic cell is completed.
