Description
Technical Field
The invention relates to an electrolytic unit structure for a high-voltage electrolytic tank and a high-voltage electrolytic tank formed by the electrolytic unit structure, and belongs to the technical field of pressure electrolytic tanks.
Background
Chinese patent publication No. CN219032404U discloses an electrolyzer for producing high pressure hydrogen and oxygen, as shown in fig. 1. The electrolytic cell comprises three regular polygon planar pieces, namely a polar plate, a sealing gasket and a diaphragm, wherein the polar plate, the sealing gasket and the diaphragm are in planar contact, and each electrolytic cell group is formed by overlapping and closely contacting a first sealing gasket 103, an anode plate 104, the first sealing gasket 103, a diaphragm 105, a second sealing gasket 106, a cathode plate 107, a second sealing gasket 106 and the diaphragm 105. Since the plates, gaskets and diaphragms of the electrolysis cell stack all lie flat against each other, a flat seal is formed between the compressed plates, gaskets and diaphragms. However, the inventors of the above patent found in the subsequent experiments of manufacturing an electrolytic cell that when a high pressure is gradually formed in the electrolytic cell as gases (hydrogen and oxygen) are continuously generated by the electrolytic reaction, gas-liquid leakage, i.e., failure of the seal, occurs between the electrode plate, the sealing gasket and the diaphragm. For this reason, the inventors of the above-mentioned patent have intensively studied the assembly sealing structure of the electrolytic cell group and made further improvements thereto.
Disclosure of Invention
The invention aims to solve the technical problems that: the electrolytic unit composition structure of the existing electrolytic tank is improved so as to meet the requirement of high-pressure electrolytic sealing, and a reliably sealed electrolytic tank is formed so as to realize high-pressure hydrogen and oxygen preparation.
The first technical scheme provided by the invention for solving the technical problems is as follows: the double-sealing gasket electrolysis unit is formed by mutually compacting a pair of electrode plates, an annular sealing gasket which is attached to the side surfaces of the electrode plates and an electrolysis diaphragm which is clamped between the opposite side surfaces of the pair of electrode plates, wherein one electrode plate is connected with a positive electrode of a power supply and the other electrode plate is connected with a negative electrode of the power supply; the annular sealing gasket is divided into an inner annular sealing gasket and an outer annular sealing gasket, the peripheral edge of the inner annular sealing gasket is matched with the inner peripheral edge of the outer annular sealing gasket, the inner annular sealing gasket is arranged on the front side surface and the back side surface of the electrode plate, and an outer annular sealing gasket is arranged between the opposite side surfaces of the pair of electrode plates; the electrolytic diaphragm covers the electrolytic area and is clamped between the two opposite inner ring gaskets, convex rings are formed on the outward empty side surfaces of the inner ring gaskets, and the diameters of the two convex rings of the two inner ring gaskets on the two opposite side surfaces of the two electrode plates of the cathode electrode plate and the anode electrode plate are different; the convex ring of the inner ring sealing gasket on one electrode plate of the pair of electrode plates is abutted against one side surface of the electrolytic diaphragm to form a first coil seal, and the convex ring of the inner ring sealing gasket on the other electrode plate is abutted against the other side surface of the electrolytic diaphragm to form a second coil seal; the first coil seal and the second coil seal are offset from each other on the circumference; the outer ring sealing gasket forms radial limit relative to the electrode plate.
The second technical scheme provided by the invention for solving the technical problems is as follows: the utility model provides a high-voltage electrolysis cell, is by a plurality of above-mentioned technical scheme one double-sealing pad electrolysis unit stack each other and compress tightly the back and constitute, feed liquor hole and corresponding membrane trompil are used for electrolyte to get into and fill up the electrolysis region of electrode plate positive and negative both sides face, two play liquid gas pocket and corresponding membrane trompil are used for exporting respectively the gas-liquid after the electrolytic reaction of cathode side and anode side.
The inventor of the present patent application studied intensively the above-mentioned assembly sealing structure of the existing electrolytic cell group: 1. the flat seal is formed among the pole plate, the sealing gasket and the diaphragm after the compression, the flatness of the sealing surfaces of the pole plate, the sealing gasket and the diaphragm is difficult to achieve high precision due to the processing precision, when the gas-liquid is gradually generated in the electrolytic reaction area to form high pressure, a large pressure difference is formed between the gas-liquid and the outside, and under the action of the large pressure difference, the sealing failure among the pole plate, the sealing gasket and the diaphragm is easy to be caused; 2. because the plane seal is formed among the polar plate, the sealing gasket and the diaphragm, the axial stress is applied to form constraint after the compression, but the constraint is not effective in the radial direction, the polar plate, the sealing gasket and the diaphragm are easy to generate tiny movement on the plane under the action force of high-pressure gas and liquid generated in an electrolytic reaction area, and the sealing among the polar plate, the sealing gasket and the diaphragm is easy to lose efficacy.
The beneficial effects of the invention are as follows: because the inner sealing gasket and the outer sealing gasket are designed to be arranged between the side surfaces of the pair of electrode plates, when the pair of electrode plates forming the cathode electrode and the anode electrode are oppositely abutted and the electrolytic diaphragm is clamped between the pair of electrode plates, the two inner ring sealing gaskets which are opposite to the side surfaces of the pair of electrode plates are respectively staggered with the two coil wire seals (the first coil wire seal and the second coil wire seal) on the two side surfaces of the electrolytic diaphragm, the plane sealing between the conventional sealing gaskets and the electrolytic diaphragm and the electrode plates is changed into the two coil wire seals, and the sealing performance is greatly improved. Meanwhile, because radial limit is formed between the outer ring sealing gasket and the electrode plates, the outer ring sealing gasket and even the inner sealing gasket can be firmly restrained between a pair of electrode plates from radial direction, and leakage caused by radial movement easily generated when the existing sealing gasket is respectively sealed with the plane between the electrolytic diaphragm and the electrode plates is avoided; so that a large pressure difference between the electrolytic reaction region and the outside can be tolerated without leakage. As for the pressure difference between the corresponding liquid inlet hole of the inner ring of the electrolytic diaphragm and the membrane opening hole of the liquid outlet hole, the sealing of the outer ring of the electrolytic diaphragm is ensured, so that the gas-liquid pressure difference of the inner ring of the electrolytic diaphragm gradually balances itself and disappears. When the high-pressure electrolytic tank is formed by the electrolytic unit, the high-pressure electrolytic tank and the electrolytic unit thereof can reach the required high pressure after continuous electrolysis without worrying about leakage, thereby realizing the high-pressure hydrogen-to-oxygen production without leakage, namely producing high-pressure hydrogen and oxygen.
Further, the surface of the outer ring sealing gasket, which is in contact with the electrode plate, is provided with grains, and when friction force is formed on the surface of the outer ring sealing gasket, which is in contact with the electrode plate, radial limit is formed between the outer ring sealing gasket and the side surface of the electrode plate.

The present embodiment provides a double-gasket electrolytic unit, as shown in fig. 2, which is constructed by pressing a pair of electrode plates 1, annular gaskets that are abutted against the side surfaces of the electrode plates 1, and an electrolytic membrane 10 interposed between the opposite side surfaces of the pair of electrode plates 1 against each other, one of the pair of electrode plates 1 being used as an anode electrode when connected to the positive electrode of a power supply, and the other electrode plate being used as a cathode electrode when connected to the negative electrode of the power supply. As shown in FIG. 5, the middle part of the front and back sides of the electrode plate 1 is provided with an electrolysis area 100 which participates in the electrolysis reaction, and a liquid inlet hole 2, two liquid outlet holes 3-1, 3-2 and a plurality of small through holes 4 are formed in the area. The electrolytic diaphragm 10 is provided with diaphragm openings corresponding to the liquid inlet holes 2 and the liquid outlet holes 3-1 and 3-2 respectively.
As shown in fig. 2, the gasket is divided into an inner ring gasket 6 and an outer ring gasket 7, the outer peripheral edge (outer peripheral edge) of the inner ring gasket 6 coincides with the inner peripheral edge (inner peripheral edge) of the outer ring gasket 7, the inner ring gasket 6 is provided on both the front and back sides of the electrode plates 1, and one outer ring gasket 7 is provided between the opposite sides of the pair of electrode plates 1. In this embodiment, the thickness of the inner ring seal 6 is substantially half that of the outer ring seal 7. The electrolysis membrane 10 covers the electrolysis zone 100 and is sandwiched between the opposing two inner ring seals 6,
as shown in fig. 3, 4 and 5, the outward facing hollow side of the inner ring seal 6 is formed with a bead 8, and the bead 8 of this embodiment is optionally an O-ring fitted over the outward facing hollow side of the inner ring seal 6. As shown in fig. 4, the diameters of the two convex rings 8 of the two inner ring gaskets 6 respectively constituting the opposite sides of the pair of electrode plates 1 of the cathode electrode plate and the anode electrode plate are different, and at this time, one outer ring gasket 7 is shared (filled) between the opposite sides of the pair of electrode plates 1.
As shown in fig. 6, the convex ring 8 of the inner ring sealing gasket 6 on one electrode plate 1 of the pair of electrode plates 1 is abutted against one side face of the electrolytic diaphragm 10 to form a first ring wire seal 5-1, and the convex ring 8 of the inner ring sealing gasket 6 on the other electrode plate 1 is abutted against the other side face of the electrolytic diaphragm 10 to form a second ring wire seal 5-2; the first coil seal 5-1 and the second coil seal 5-2 are offset from each other on the circumference. The surface of the outer ring gasket 7 contacting the electrode plate 1 is textured, so that when the outer ring gasket 7 contacts the electrode plate 1, a large friction force is formed on the contact surface and a limit is formed between the outer ring gasket 7 and the side surface of the electrode plate 1 in the radial direction (in the direction of the side surface of the electrode plate 1 outwards).
Example two
The present embodiment provides a second type of double-gasket electrolytic unit, as shown in fig. 7, 8, 9 and 10, which is a variation on the structure of the double-gasket electrolytic unit of the first embodiment, except that the same is as the first embodiment, except that: a bulge 9 is arranged on the side surface of the electrode plate 1, and a groove 11 which can be embedded by the bulge 9 is arranged on the outer ring sealing gasket 7 oppositely; it is of course also possible to provide the outer ring seal 7 with projections 9 and the opposite side of the electrode plate 1 with recesses 11 into which the projections 9 engage. The surfaces of the outer ring gasket 7 contacting the electrode plate 1 are thus formed with protrusions 9 and grooves 11, respectively, which are nested in each other. As shown in fig. 10, the protrusions 9 and the grooves 11 are arranged in three circles (three groups) along the circumferential array of the outer ring gasket 7 and the electrode plate 1, and of course, one circle, half circle or other arrangement forms are also possible. Thus, when the outer ring gasket 7 is brought into contact with the electrode plate 1, the protrusions 9 and the grooves 11 of the contact surfaces thereof are nested with each other, so that the outer ring gasket 7 and the electrode plate 1 form a restriction between the sides in the radial direction (in the outward direction in the side of the electrode plate 1).
Example III
The present embodiment provides a third double-gasket electrolytic unit, as shown in fig. 11 and 12, which is a variation on the structure of the double-gasket electrolytic unit of the first embodiment, except that it is the same as the first embodiment: a baffle 12 is provided on the outer peripheral side of the outer ring gasket 7, and the baffle 12 is fixedly coupled to the electrode plate 1 by bolts 13. Of course, the bolts 13 may be removed, and the baffle plate 12 may be directly welded to the electrode plate 1. This forms a limit between the outer ring gasket 7 and the side surface of the electrode plate 1 in the radial direction (in the direction of the outside in the side surface of the electrode plate 1).
Example IV
The embodiment provides a high-voltage electrolytic tank, as shown in fig. 13, which is formed by stacking and pressing a plurality of double-sealing gasket electrolytic units in the first embodiment, wherein the liquid inlet hole 2 of the electrode plate 1 and the second opening 20 on the corresponding electrolytic membrane 10 are used for allowing electrolyte to enter and fill the electrolytic areas 100 on the front side and the back side of the electrode plate, and the two liquid outlet holes 3-1, 3-2 and the second openings 10-1, 10-2 on the corresponding electrolytic membrane 10 are used for respectively leading out gas and liquid after the electrolytic reaction on the cathode side and the anode side.
It is obvious that, in addition to the high-voltage electrolytic tank of this embodiment, which is formed by stacking and pressing the double-seal-gasket electrolytic cells of the first embodiment, the high-voltage electrolytic tank may be formed by stacking and pressing the double-seal-gasket electrolytic cells of the second or third embodiments.

1) The convex rings 8 are respectively adhesive tapes adhered to the outward empty side surfaces of the inner ring sealing gaskets 6;
2) The bead 8 is a coating layer such as a ceramic coating layer or the like formed on the hollow side surface of the inner ring gasket 6 facing outward;
3) The bead 8 is a bead made integrally with the inner ring seal 6, i.e. the bead 8 is part of the same material as the inner ring seal 6.
4) The cross-sectional shape of the bead 8 may be formed of any reasonable shape other than O-shape, for example: triangle, trapezoid, quadrilateral, or prism, etc.
5) The number of beads 8 used as a seal is not limited, and may be 1, 2, 3, 4, 5, or the like.
