Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, specifically to an electrolytic cell connecting pipe and its electrolysis device. Background Technology

[0002] The volume of the product at the outlet of a gas-producing electrolyzer is generally larger than that at the inlet. Especially when a large amount of gas is generated, a large amount of gas and electrolyte must be collected in the collection pipe through the outlet pipe. The outlet pipe and the collection pipe are generally connected by a corrosion-resistant flexible hose. The hose can ensure that the product (gas-liquid mixture) can flow into the collection pipe quickly, avoiding the temporary accumulation of gas-liquid mixture that causes pressure fluctuations inside the electrolyzer.

[0003] When both gas and liquid flow from the outlet pipe to the hose, the liquid is more likely to generate vortices at the hose inlet, causing momentary liquid blockage and resulting in pressure buildup. The resulting pressure fluctuations will affect the safe and stable operation of the device. Utility Model Content

[0006] (II) Technical Solution

[0046] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] See Figure 1 This utility model provides an electrolytic cell connecting pipe 2, one end of which is connected to the electrolytic cell outlet pipe 12, and the other end is connected to the collection pipe connector 31. The electrolytic cell connecting pipe 2 includes an upper connector, a funnel-shaped opening 23, a pipe body 24, and a lower connector; the electrolytic cell outlet pipe 12 and the large-diameter end of the funnel-shaped opening 23 are connected through the upper connector; the small-diameter end of the funnel-shaped opening 23 is connected to the first end of the pipe body 24; and the second end of the pipe body 24 is connected to the collection pipe connector 31 through the lower connector.

[0051] The electrolytic cell connecting pipe 2 is equivalent to a traditional flexible hose structure, used to transport the electrolyzed gas-liquid mixture to the main pipe connector 31. The upper and lower connectors are connecting components between corresponding pipes, serving to connect and seal. Optionally, the funnel opening 23 is integrally formed with the pipe body 24 to ensure the integrity of the electrolytic cell connecting pipe 2 and guarantee the sealing effect.

[0052] The electrolytic cell connecting pipe 2 adopts a funnel-like structure, namely the funnel opening 23. Compared with the traditional method of directly connecting the outlet pipe and the hose, the funnel opening 23 can expand the inflow area of ​​the liquid and automatically complete the pressure relief. This greatly reduces the possibility of the gas-liquid mixture generating a closed vortex at the moment of entering the electrolytic cell connecting pipe 2, effectively avoiding instantaneous liquid blockage, thereby avoiding local pressure buildup and reducing pressure fluctuations during the electrolysis process.

[0053] like Figure 4 As shown, the width of the cross-section of the large-diameter end of the funnel opening 23 is W, and the length is L; L / W > 1. Specifically, when L / W > 1, after the liquid enters the funnel opening 23, it is difficult to quickly fill the entire length of the funnel opening 23, allowing the liquid to release pressure in the length direction and increasing the pressure threshold.

[0054] Furthermore, the cone angle of the funnel opening 23 is b; 10°≤b≤90°, preferably 30°≤b≤45°. If the angle b is too small, the difference in opening area between the large and small diameter ends of the funnel opening 23 will be small, making it difficult to play the role of converging and transitioning, and increasing the risk of pressure buildup; if the angle b is too large, it will increase the difficulty of processing and installation.

[0055] Secondly, the angle between the generatrix of the end of the funnel opening 23 facing the electrolytic cell and the horizontal plane is α; α > 0°. Specifically, when installing the electrolytic cell connecting pipe 2, the angle α should be greater than 0°, that is, the funnel opening 23 is tilted at an angle α. This allows the liquid to flow down the lower inner wall of the funnel opening 23 under gravity after the gas-liquid mixture is depressurized, while the gas flows smoothly through the upper inner wall of the funnel opening 23, avoiding gas-liquid accumulation and effectively completing gas-liquid separation. Furthermore, α > 0° effectively prevents liquid backflow or accumulation, facilitating the smooth flow of liquid out along the lower inner wall of the funnel opening 23.

[0056] In addition, the cross-section of the large-diameter end of the funnel opening 23 is a flattened circle, a rounded rectangle, or a long groove. For example... Figure 4 and Figure 5 As shown, the funnel opening 23 is configured as a long groove shape and a flat oval shape, or other cross-sectional shapes with L / W > 1. Optionally, the outer wall shape of the funnel opening 23 does not have to be funnel-shaped, as long as the inner groove of the funnel opening 23 is funnel-shaped, thereby minimizing the wall thickness of the funnel opening 23 and saving material costs.

[0057] Optionally, a flexible section 25 is provided on the second end of the tube body 24 to allow the funnel opening 23 to swing relative to the conduit pipe 31. Specifically, the tube body 24 can be a flexible tube or a rigid tube. In this embodiment, the flexible section 25 has a spiral groove 25 formed in the axial direction of the tube body 24. The spiral groove 25 makes the tube body 24 more flexible, facilitating the adjustment of the installation angle of the tube body 24 port during connection and improving the flexibility of installation.

[0058] See Figure 2 The upper connecting component includes a first sealing gasket 6 and a pair of mating parts 22. The pair of mating parts 22 are correspondingly positioned on the large-diameter ends of the electrolytic cell outlet pipe 12 and the funnel opening 23. The first sealing gasket 6 is sandwiched between the pair of mating parts 22. The pair of mating parts 22 are detachably connected. Specifically, the first sealing gasket 6 can be a rubber gasket with a through hole in the center for gas and liquid to pass through. The first sealing gasket 6 is pressed between the pair of mating parts 22 to seal the through hole. The mating parts 22 can be flanges, connected by easily disassembled components such as bolts or pins. In this embodiment, the mating parts 22 penetrate the first sealing gasket 6 and the pair of mating parts 22 to ensure that the first sealing gasket 6 will not misalign relative to the mating parts 22 during electrolysis, thus ensuring the sealing effect of the first sealing gasket 6.

[0059] Furthermore, the upper connecting member also includes a first sealing platform 21; the first sealing platform 21 is coaxially disposed on the end face of the mating member 22; the diameter of the first sealing platform 21 is smaller than the diameter of the mating member 22; a first sealing gasket 6 is held between a pair of first sealing platforms 21; the pair of mating members 22 are detachably connected. Specifically, the first sealing platform 21 and the mating member 22 can be integrally disposed, both being in the shape of a boss, pressing the first sealing gasket 6 between a pair of first sealing platforms 21. Optionally, at least three bolts are wound around the side of the first sealing platform 21 and abut against the side wall of the first sealing platform 21 to radially limit the first sealing gasket 6, effectively preventing the first sealing gasket 6 from coming off the pair of first sealing platforms 21. Multiple arc-shaped grooves can also be further formed at the edges of the first sealing platform 21 and the first sealing gasket 6, with the bolts located inside the arc-shaped grooves, further enhancing the limiting strength of the bolts on the first sealing gasket 6 and effectively preventing the first sealing gasket 6 from moving or shifting under pressure.

[0060] like Figure 3 As shown, the lower connector includes a connecting cap 26, a second sealing platform 27, and a second sealing gasket 7. The connecting cap 26 is connected to the second end of the pipe body 24; the connecting cap 26 is also connected to one end of the main pipe connector 31; the second sealing platform 27 is a concave disc; and the second sealing gasket 7 is disposed between the second sealing platform 27 and the main pipe connector 31. Specifically, the second sealing gasket 7 can be a rubber gasket. The connecting cap 26 and the main pipe connector 31 are connected, and the two can be connected by threads. The second sealing gasket 7 is pressed between the main pipe connector 31 and the main pipe connector 31.

[0061] In addition, see Figure 6This utility model also provides an electrolysis device, which includes the electrolysis cell connecting pipe 2 as described above; the electrolysis device also includes an electrolysis cell 1, an outlet concentrator pipe 3, an inlet concentrator pipe 4, and an inlet connecting pipe 5; one end of the inlet connecting pipe 5 is connected to the inlet concentrator pipe 4, and the other end is connected to the electrolysis cell inlet pipe 11 of the electrolysis cell 1; one end of the electrolysis cell connecting pipe 2 is connected to the outlet concentrator pipe 3, and the other end is connected to the electrolysis cell outlet pipe 12 of the electrolysis cell 1. Specifically, the inside of the electrolysis cell 1 is an electrolysis chamber. The electrolyte is discharged into the electrolysis chamber through the inlet concentrator pipe 4, the inlet connecting pipe 5, and the electrolysis cell inlet pipe 11 for electrolysis reaction. The gas-liquid mixture after the reaction is then discharged into the outlet concentrator pipe 3 through the electrolysis cell outlet pipe 12 and the electrolysis cell connecting pipe 2, and the separated gas and liquid are transported to a designated location by the outlet concentrator pipe 3.

[0062] The electrolysis device of this invention increases the transition area when the electrolysis cell outlet pipe 12 flows into the electrolysis cell connecting pipe 2 by designing a funnel-shaped opening on the electrolysis cell connecting pipe 2. This can effectively reduce the occurrence of instantaneous liquid blockage and avoid gas blockage and pressure buildup. It is practical and applicable to different gas-producing electrolysis cells and is easy to operate.

However, this utility model is not limited to the specific embodiments described above.
