[0027] The utility model provides an electrolytic cell polar plate.
[0028] In the embodiment of the present utility model, Figure 1As shown, the electrode plate of the electrolytic cell includes an electrode frame 100, a main electrode plate 200, a guide rib plate group 300 and a plurality of redistribution structures 400; the electrode frame 100 is provided with an electrolyte inlet 101 and a gas outlet 102; the main electrode plate 200 is installed in the electrode frame 100; the guide rib plate group 300 is arranged on the main electrode plate 200, and at least two groups are provided in the direction from the electrolyte inlet 101 to the gas outlet 102; each group of guide rib plate groups 300 includes at least two sub-rib plates 310, and a guide channel 320 is formed between at least two sub-rib plates 310, and the guide channel 320 extends from the electrolyte inlet 101 to the gas outlet 102; at least one redistribution structure 400 is arranged between two adjacent groups of guide rib plate groups 300, and is connected to the guide channels 320 formed in the two adjacent groups of guide rib plate groups 300.
[0029] When the main pole plate 200 is installed in the pole frame 100, it can be connected to the pole frame 100 by bonding or welding, so as to reduce the risk of electrolyte leakage. It should be noted that during the electrolysis process, the electrolytic cell plates are relatively arranged with two, that is, the two main pole plates 200 are relatively arranged and formed with a gap, so that the gap is an electrolysis chamber. By providing an electrolyte inlet 101 and a gas outlet 102 on the pole frame 100, the electrolyte enters the electrolysis chamber formed by the main pole plate 200 from the electrolyte inlet 101, so as to generate gas by electrolysis in the electrolysis chamber, so that the gas is discharged from the gas outlet 102. Usually, the electrolyte inlet 101 is opened at the bottom of the pole frame 100, and the gas outlet 102 is opened at the top of the pole frame 100.
[0030] A guide rib group 300 is further provided on the main electrode plate 200, and each guide rib group 300 includes at least two sub-ribs 310, and a guide channel 320 is formed between at least two sub-ribs 310, and the guide channel 320 extends from the electrolyte inlet 101 to the gas outlet 102, so that the electrolyte entering the electrolysis chamber from the electrolyte inlet 101 can flow along the guide channel 320 in a specific direction. By providing at least two groups of guide rib groups 300 in the direction from the electrolyte inlet 101 to the gas outlet 102, and at least one redistribution structure 400 is provided between two adjacent groups of guide rib groups 300 and is connected to the guide channels 320 in the two adjacent groups of guide rib groups 300, the electrolyte in each guide channel 320 near the electrolyte inlet 101 is converged into the redistribution structure 400, fully mixed by the redistribution structure 400, and then redistributed to the guide channel 320 between another group of guide rib groups 300, that is, by providing at least one redistribution structure in the middle of a longer flow path, the electrolyte in the guide channel 320 can be redistributed, so that the electrolyte entering each guide channel 320 is more uniform, thereby improving the dead zone and uneven flow of the electrolyte in the electrolytic cell plate.
[0031] Specifically, the sub-ribs 310 in the guide rib group 300 can be connected to the main pole plate 200 by welding, bonding or integral molding. The guide channel 320 can be a straight channel or a curved channel. In order to reduce the resistance to the flow of electrolyte and gas and the risk of dead zones, the guide channel 320 can be preferably a straight channel. The redistribution structure 400 can be a tubular body with a tube wall, or the redistribution structure 400 can be a box-type structure with a box shell, or the redistribution structure 400 can be a gap structure formed between two adjacent groups of guide rib groups 300, as long as the liquid and gas in at least two guide channels 320 formed in each guide rib group 300 on both sides of the redistribution structure 400 can all converge to the redistribution structure 400. In addition, a redistribution structure 400 may be provided between two adjacent groups of guide rib groups 300, and all guide channels 320 formed in the two groups of guide rib groups 300 adjacent to the redistribution structure 400 are connected to the redistribution structure 400; or at least two redistribution structures 400 may be provided between two adjacent groups of guide rib groups 300, and at least two redistribution structures 400 are respectively connected to part of the guide channels 320 formed in each guide rib group 300 on the two adjacent sides.
[0032] The technical solution of the utility model is that the pole frame 100 is provided with an electrolyte inlet 101 and a gas outlet 102, and the main pole plate 200 is installed in the pole frame 100, so that the electrolyte can flow into the electrolyte inlet 101 and flow through the main pole plate 200 and then flow out from the gas outlet 102. By arranging the guide rib plate group 300 on the main pole plate 200, each guide rib plate group 300 includes at least two sub-rib plates 310, and a guide channel 320 is formed between the two sub-rib plates 310, and the guide channel 320 extends from the electrolyte inlet 101 to the gas outlet 102, so that the electrolyte can flow along the predetermined guide channel 320 when flowing through the main pole plate 200, thereby providing guidance for the flow of the electrolyte, reducing the risk of electrolyte backflow, and making the electrolyte more evenly distributed on the main pole plate 200. Furthermore, at least two groups of guide rib groups 300 are provided in the direction from the electrolyte inlet 101 to the gas outlet 102, and at least one redistribution structure 400 is provided between two adjacent groups of guide rib groups 300, and is connected to the guide channels 320 formed in the two adjacent groups of guide rib groups 300, so that the electrolyte flows through a longer path from the electrolyte inlet 101 to the gas outlet 102 and passes through the redistribution structure 400 at least once for re-merging and redistribution, so that the electrolyte and gas are more evenly distributed when they enter the subsequent guide channel 320 after passing through the redistribution structure 400.
[0033] In an example, please refer to Figure 1 and Figure 2Two adjacent groups of guide rib plate groups 300 are arranged at intervals, and the gap between the two adjacent groups of guide rib plate groups 300 forms a redistribution structure 400.
[0034] By forming the redistribution structure 400 with the gap between two adjacent groups of guide ribs, the material cost of the guide rib group 300 and the material cost of the redistribution structure 400 can be saved at the same time.
[0035] Specifically, there may be two, three or more guide rib groups 300, and a gap may be provided between each two adjacent guide rib groups 300, and the gap forms a redistribution structure 400. Alternatively, the above-mentioned box-type or tubular redistribution structure 400 may be provided between at least two groups of guide ribs.
[0036] In one example, if Figure 3 As shown, a gap d is provided between any sub-rib plate 310 and the pole frame 100 .
[0037] By providing a gap d between the sub-rib plate 310 and the pole frame 100, it can be ensured that after the electrolyte flows into the main pole plate 200 from the electrolyte inlet 101, it can flow into each guide channel 320 formed in the guide rib plate group 300 adjacent to the electrolyte inlet 101, thereby improving the uniformity of the electrolyte distribution in the main pole plate 200.
[0038] Furthermore, if Figure 1 As shown, at least one redistribution structure 400 is disposed at the inlet side of the guide channel 320 near the electrolyte inlet 101 .
[0039] By arranging at least one redistribution structure 400 on the inlet side of the guide channel 320 near the electrolyte inlet 101, the electrolyte flowing out of the electrolyte inlet 101 can first pass through the primary redistribution structure 400 to be converged and evenly distributed into the guide channel 320 near the electrolyte inlet 101, thereby improving the probability of uniform distribution of the electrolyte.
[0040] In one example, if Figure 2 As shown, the sub-ribs 310 of two adjacent groups of guide rib groups 300 are staggered.
[0041] By staggering the sub-ribs 310 of two adjacent groups of guide rib groups 300, the disturbance intensity after the redistribution of the electrolyte and gas between the two groups of guide rib groups 300 can be enhanced, so that the gas attached to the main electrode plate 200 can be taken away in time, and the uniformity of the electrolyte distribution after redistribution can be improved.
[0042] Furthermore, if Figure 2 As shown, the intervals between each two adjacent sub-ribs 310 in the same guide rib group 300 are equal.
[0043] By setting in this way, the situation that the cross-sectional areas of the guide channels 320 in the same guide rib plate group 300 are different can be reduced, thereby reducing the flow bias of the electrolyte, making the flow rate of the electrolyte entering each guide channel 320 equal, thereby ensuring the uniform distribution of the electrolyte in the main electrode plate 200. At the same time, the electrolyte passing through each sub-rib plate 310 is evenly distributed.
[0044] Furthermore, if Figure 2 As shown, the spacing between two adjacent sub-ribs 310 in the same group of guide ribs 300 is defined as L; in the extension direction perpendicular to the sub-ribs 310 and the direction perpendicular to the main pole plate 200, the offset distance between the sub-ribs 310 of two adjacent groups of guide ribs 300 is 2 / L.
[0045] With such a configuration, the electrolyte flowing out of the guide channel 320 in the front guide rib plate group 300 can flow evenly into the two adjacent guide channels 320 in the rear guide rib plate group 300, thereby ensuring that the flow rate of the electrolyte in each guide channel 320 in the rear guide rib plate group 300 remains relatively even. Moreover, with such a configuration, the sub-rib plate 310 in the rear guide rib plate group 300 can have a comparable disturbance intensity to the electrolyte and gas that are about to enter the two adjacent guide channels 320, thereby ensuring that more gas on the main pole plate 200 is taken away.
[0046] In one example, the sub-rib plate 310 is provided with openings, and the openings are connected to the guide channels 320 on both sides of the sub-rib plate 310 .
[0047] This arrangement facilitates the fluids in the guide channels 320 on the adjacent sides of the sub-rib plate 310 to circulate with each other, thereby reducing the risk of the fluid being retained in a guide channel 320. Specifically, the opening shape can be circular, rectangular, diamond or other shapes.
[0048] In one example, the plate surface of the sub-rib plate 310 facing the guide channel 320 is rectangular, and the length direction of the plate surface of the sub-rib plate 310 facing the guide channel 320 is consistent with the extension direction of the guide channel 320 .
[0049] By setting the plate surface of the sub-rib plate 310 facing the flow guide channel 320 in a rectangular shape, the plate surface of the sub-rib plate 310 facing the flow guide channel 320 is made to be a flat surface, so that when the electrolyte or gas flows through the flow guide channel 320 on both sides of the sub-rib plate 310, the flow resistance is small and the flow is smoother. In addition, by aligning the length direction of the plate surface of the sub-rib plate 310 facing the flow guide channel 320 with the extension direction of the flow guide channel 320, the sub-rib plate 310 has a better flow guiding effect on the electrolyte and gas.
[0050] Of course, in other examples, the plate surface of the sub-rib plate 310 facing the flow guide channel 320 may also be in the shape of a parallelogram, a pentagon, a hexagon, etc., as long as it can ensure a good flow guide effect.
[0051] In one example, the thickness dimension of the sub-rib plate 310 is D, 1 mm ≤ D ≤ 2 mm.
[0052] Specifically, the thickness dimension D of the sub-rib plate 310 can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2.0 mm. By setting the thickness dimension D of the sub-rib plate 310 to be not less than 1 mm, the cross-sectional area of the sub-rib plate 310 can be made larger, thereby reducing the current density. By setting the thickness dimension D of the sub-rib plate 310 to be not more than 2 mm, the space and weight occupied by the sub-rib plate 310 can be reduced, so that more electrolyte can flow in the guide channel 320 and the weight and material cost of the entire electrolytic cell plate can be reduced.
[0053] The utility model also proposes an electrolysis device, which includes an electrolytic cell plate. The specific structure of the electrolytic cell plate refers to the above embodiment. Since the electrolysis device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0054] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
