Description

Technical Field

[0001] The present application relates to the technical field of electrolytic cells, and in particular to an electrolytic device with a fish-scale net structure. Background Art

[0002] In an electrolytic cell, when current passes through the electrolyte (usually water), water molecules undergo an oxidation-reduction reaction on the electrode, thereby releasing hydrogen and oxygen. At the anode electrode, water molecules lose electrons to produce oxygen molecules, which gather together to form bubbles covering the surface of the anode electrode. At the cathode electrode, hydrated hydrogen ions gain electrons to produce hydrogen molecules, which also gather together to form bubbles covering the surface of the cathode electrode. These bubbles hinder the migration of ions, thereby increasing the solution resistance and reducing the effective working area of ​​the electrode, thereby affecting the electrolysis efficiency.

[0047] The present application provides an electrolysis device with a fish-scale net structure, comprising: a first end plate 110, a second end plate 120, an anode electrolysis chamber, a cathode electrolysis chamber and an ion exchange membrane 500; the anode electrolysis chamber, the ion exchange membrane 500 and the cathode electrolysis chamber are sequentially arranged between the first end plate 110 and the second end plate 120; the internal cavity of the anode electrolysis chamber and the internal cavity of the cathode electrolysis chamber are suitable for being separated by the ion exchange membrane 500; the anode electrode 200 and the first fish-scale net support layer 410 are provided in close contact with each other in the anode electrolysis chamber; the cathode electrode 300 and the second fish-scale net support layer 420 are provided in close contact with each other in the cathode electrolysis chamber; the first The end plate 110 and the second end plate 120 are both provided with a cathode electrolyte inlet, a cathode gas-liquid outlet, an anode electrolyte inlet and an anode gas-liquid outlet; the cathode electrolyte inlet 113 and the cathode gas-liquid outlet 114 of the first end plate 110, and the cathode electrolyte inlet 123 and the cathode gas-liquid outlet 124 of the second end plate 120 are all connected to the internal cavity of the cathode electrolysis chamber; the anode electrolyte inlet 111 of the first end plate 110 and the anode gas-liquid outlet 112 of the first end plate 110, the anode electrolyte inlet 121 of the second end plate 120, and the anode gas-liquid outlet 122 of the second end plate 120 are all connected to the internal cavity of the anode electrolysis chamber.

[0048] It should be noted that the ion exchange membrane 500 can prevent the oxygen / hydrogen generated in the anode electrode 200 chamber and the cathode electrode 300 chamber from mixing, which can increase the safety of the electrolysis process. The electrolyte flows into the anode electrolyte inlet 111 of the first end plate 110 and the anode electrolyte inlet 121 of the second end plate 120 respectively. The anode electrode 200 in the anode electrolyte chamber electrolyzes the electrolyte to produce oxygen. The oxygen produced by the electrolysis flows into the anode electrolyte inlet 111 of the first end plate 110 and the cathode electrode 300 respectively. The electrolyte flows into the cathode electrolysis chamber through the cathode electrolyte inlet 113 of the first end plate 110 and the cathode electrolyte inlet 123 of the second end plate 120 respectively, and the cathode electrode 300 in the cathode electrolysis chamber electrolyzes the electrolyte to produce hydrogen, and the hydrogen produced by electrolysis is collected through the cathode gas-liquid outlet 114 of the first end plate 110 and the cathode gas-liquid outlet 124 of the second end plate 120 respectively.

[0049] During the process of hydrogen production by electrolysis of water, bubbles formed by oxygen / hydrogen adhere to the outer surface of the anode electrode 200 / cathode electrode 300, thereby hindering the further progress of the electrolysis reaction. By arranging a first fish scale mesh support layer 410 in the anode electrolysis chamber and a second fish scale mesh support layer 420 in the cathode electrolysis chamber, the first fish scale mesh support layer 410 and the second fish scale mesh support layer 420 provide a channel for the overflow of bubbles, thereby accelerating the shedding of bubbles attached to the outer surface of the anode electrode 200 / cathode electrode 300, thereby reducing the bubble coverage rate of the outer surface of the anode electrode 200 / cathode electrode 300, effectively increasing the contact area between the anode electrode 200 / cathode electrode 300 and the electrolyte, and improving the conversion efficiency of the electrolysis.

[0050] Furthermore, the main bodies of the anode electrode 200 and the cathode electrode 300 are both rectangular plate structures, which provide a larger contact area, so that the chemical reaction between the anode electrode 200 / cathode electrode 300 and the electrolyte can be carried out on a relatively uniform and stable interface.

[0051] Furthermore, the first end plate 110 is disposed on the side of the anode electrode 200 chamber away from the ion exchange membrane 500, and the second end plate 120 is disposed on the side of the cathode electrode 300 chamber away from the ion exchange membrane 500. The cathode electrolyte inlet 113, cathode gas-liquid outlet 114, anolyte inlet 111, and anode gas-liquid outlet 112 are respectively disposed at the four corners of the first end plate 110. Furthermore, the anolyte inlet 111 and the anode gas-liquid outlet 112 are located at one pair of diagonally opposite corners of the first end plate 110, and the cathode electrolyte inlet 113 and the cathode gas-liquid outlet 114 are located at the other pair of diagonally opposite corners of the first end plate 110, and the anolyte inlet 111 and the anode gas-liquid outlet 112 are disposed symmetrically with the cathode electrolyte inlet 113 and the cathode gas-liquid outlet 114, respectively.

[0052] Furthermore, the cathode electrolyte inlet 123, cathode gas-liquid outlet 124, anode electrolyte inlet 121 and anode gas-liquid outlet 122 of the second end plate 120 are arranged at the same positions as those of the first end plate 110, which have been described in detail above and will not be repeated here.

[0053] In one possible implementation, the first fish-scale mesh support layer 410 and the second fish-scale mesh support layer 420 are both rectangular plate-shaped structures, and each of the first fish-scale mesh support layer 410 and the second fish-scale mesh support layer 420 has two or more fish-scale holes, which are arranged in an array. It should be noted that the outer contour of the first fish-scale mesh support layer 410 matches the outer contour of the anode electrode 200, and the outer contour of the second fish-scale mesh support layer 420 matches the outer contour of the cathode electrode 300, ensuring that the anode electrode 200 and the first fish-scale mesh support layer 410 (or the cathode electrode 300 and the second fish-scale mesh support layer 420) can fit seamlessly and tightly during installation and use, thereby improving the stability of the overall structure.

[0054] Both the first fish scale mesh support layer 410 and the second fish scale mesh support layer 420 have more than two fish scale holes. The arrayed fish scale holes allow the electrolyte to contact the anode electrode 200 / cathode electrode 300 more evenly, while providing a channel for the bubbles generated on the outer surface of the anode electrode 200 / cathode electrode 300 to overflow, thereby improving the electrolysis efficiency.

[0055] In one possible implementation, the anode electrolysis chamber includes: a terminal plate 210, a first sealing gasket 220, a first flow channel plate frame 240 and a second sealing gasket 230 stacked in sequence; the terminal plate 210 is tightly fitted to the first end plate 110, and the second sealing gasket 230 is tightly fitted to the ion exchange membrane 500; corresponding first clearance holes are opened in the middle of the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230, each first clearance hole is matched with the anode electrode 200 and the first fish scale mesh support layer 410, and the anode electrode 200 and the first fish scale mesh support layer 410 are arranged in the first clearance hole.

[0056] It should be noted here that when the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230 are tightly fitted, the clearance hole 225 in the middle of the first sealing gasket 220, the clearance hole 245 in the middle of the first flow channel plate frame 240, and the clearance hole 235 in the middle of the second sealing gasket 230 form an internal cavity of the anode electrolysis chamber, which is suitable for placing the anode electrode 200 and the first fish scale mesh support layer 410. The internal cavity of the anode electrolysis chamber provides a stable support platform for the anode electrode 200 and the first fish scale mesh support layer 410, avoiding The anode electrode 200 and the first fish-scale mesh support layer 410 are prevented from being displaced or damaged due to vibration or impact, ensuring that the anode electrode 200 and the first fish-scale mesh support layer 410 maintain a stable position and shape during the electrolysis process. The output end of the terminal block 210 is connected to the input end of the electrolysis device, which is suitable for providing current to the electrolysis device. The input end of the terminal block 210 is connected to an external power supply. The first sealing gasket 220 and the second sealing gasket 230 are suitable for preventing leakage of electrolyte or oxygen in the anode electrolysis chamber cavity, thereby improving the electrolysis efficiency.

[0057] In one possible implementation, the cathode electrolysis chamber includes: a third sealing gasket 320, a second flow channel plate frame 340, a fourth sealing gasket 330 and a bipolar plate 310 stacked in sequence; the bipolar plate 310 is tightly fitted with the second end plate 120, and the third sealing gasket 320 is tightly fitted with the ion exchange membrane 500. Corresponding second clearance holes are opened in the middle of the third sealing gasket 320, the second flow channel plate frame 340 and the fourth sealing gasket 330, and each second clearance hole is matched with the cathode electrode 300 and the second fish scale mesh support layer 420, and the cathode electrode 300 and the second fish scale mesh support layer 420 are arranged in the second clearance hole.

[0058] It should be noted here that when the third sealing gasket 320, the second flow channel plate frame 340, and the fourth sealing gasket 330 are tightly fitted, the clearance hole 325 in the middle of the third sealing gasket 320, the clearance hole 345 in the middle of the second flow channel plate frame 340, and the clearance hole 335 in the middle of the fourth sealing gasket 330 form an internal cavity of the cathode electrolysis chamber, which is suitable for placing the cathode electrode 300 and the second fish scale mesh support layer 420. The internal cavity of the cathode electrolysis chamber provides a stable support platform for the cathode electrode 300 and the second fish scale mesh support layer 420, avoiding the cathode The cathode electrode 300 and the second fish-scale mesh support layer 420 are prevented from displacement or damage due to vibration or impact, ensuring that the cathode electrode 300 and the second fish-scale mesh support layer 420 maintain a stable position and shape during the electrolysis process. The bipolar plate 310 provides the necessary conductivity path for the decomposition and movement of ions in the electrolyte under the action of the electric field, avoiding short circuit in the electrolysis device and ensuring the safety of the electrolysis process. The third sealing gasket 320 and the fourth sealing gasket 330 are suitable for preventing leakage of electrolyte or hydrogen in the cathode electrolysis chamber cavity, thereby improving the electrolysis efficiency.

[0059] In one possible implementation, the terminal plate 210, the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230 stacked in sequence are all provided with anode liquid inlet circulation holes, anode liquid outlet circulation holes, cathode liquid inlet circulation holes and cathode liquid outlet circulation holes; the third sealing gasket 320, the second flow channel plate frame 340, the fourth sealing gasket 330 and the bipolar plate 310 stacked in sequence are all provided with anode liquid inlet circulation holes, anode liquid outlet circulation holes, cathode liquid inlet circulation holes and cathode liquid outlet circulation holes.

The anode liquid inlet flow hole 241 of the first flow channel plate frame 240 is connected to the anode liquid outlet flow hole 242 of the first flow channel plate frame 240 through the first clearance hole 245 of the first flow channel plate frame 240, which is suitable for allowing the anode electrolyte to flow through the anode electrode 200 in the first clearance hole 245 of the first flow channel plate frame 240.

[0061] The electrolyte enters the anolyte inlet of the first end plate 110 and the second end plate 120, respectively, and flows through the anolyte inlet channel into the interior of the anolyzer chamber. The anode electrode 200 in the anolyzer chamber electrolyzes the electrolyte to produce oxygen, which is then discharged through the anolyte gas-liquid outlet channel from the anode gas-liquid outlet 112 of the first end plate 110 and the anode gas-liquid outlet 122 of the second end plate 120. These two outlets enable faster discharge of the oxygen generated in the anolyzer chamber, reducing the time that oxygen accumulates in the anolyzer chamber and improving reaction efficiency.

The anode electrode 200 in the anode electrolysis chamber cavity electrolyzes the electrolyte to produce oxygen, which enters the anode electrolyte gas-liquid outlet channel through the anode liquid outlet tank 247 and is discharged. The anode liquid inlet flow hole 241 and the anode liquid outlet flow hole 242 of the first flow channel plate frame 240 are correspondingly arranged with the anode liquid inlet tank 246 and the anode liquid outlet tank 247. By arranging the anode liquid inlet tank 246 and the anode liquid outlet tank 247 in a diagonal manner, it is helpful to guide the electrolyte to flow more evenly in the anode electrolysis chamber, improve the mass transfer capacity in the anode electrolysis chamber, better utilize the internal space of the anode electrolysis chamber, reduce dead corner areas, and ensure that the electrolysis reaction is more sufficient and efficient.

[0067] Here, it should be noted that the terminal plate 210, the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230, the third sealing gasket 320, the second flow channel plate frame 340, the fourth sealing gasket 330 and the bipolar plate 310 are stacked and tightly fitted with no gaps between them. The electrolyte can only enter the cavity of the anode electrolysis chamber through the anode liquid outlet groove 247 and the anode liquid inlet groove 246.

[0068] In one possible implementation, a cathode liquid inlet groove 346 and a cathode liquid outlet groove 347 are provided on the side of the second flow channel plate frame 340 facing the third sealing gasket 320; the cathode liquid inlet circulation hole 343 of the second flow channel plate frame 340 is connected to the second give-way hole 345 of the second flow channel plate frame 340 through the cathode liquid inlet groove 346, and the second give-way hole 345 of the second flow channel plate frame 340 is connected to the cathode liquid outlet circulation hole 344 of the second flow channel plate frame 340 through the cathode liquid outlet groove 347.

[0069] The cathode liquid inlet trough 346 is suitable for introducing the electrolyte in the cathode liquid inlet channel into the cavity of the cathode electrode 300 chamber. The cathode electrode 300 in the cathode electrolysis chamber electrolyzes the electrolyte to produce hydrogen, and the hydrogen enters the cathode electrolyte gas-liquid outlet channel through the cathode liquid outlet trough 347 and is discharged. It should be noted here that the cathode liquid inlet flow hole 343 and the cathode liquid outlet flow hole 344 of the second flow channel plate frame 340 are arranged corresponding to the cathode liquid inlet trough 346 and the cathode liquid outlet trough 347. By arranging the cathode liquid inlet trough 346 and the cathode liquid outlet trough 347 in a diagonal manner, it is helpful to guide the electrolyte to flow more evenly in the cathode electrolysis chamber, improve the mass transfer capacity inside the cathode electrolysis chamber, better utilize the internal space of the cathode electrolysis chamber, reduce the dead angle area, and ensure that the electrolysis reaction is more sufficient and efficient.

[0070] Here, it should be noted that the terminal plate 210, the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230, the third sealing gasket 320, the second flow channel plate frame 340, the fourth sealing gasket 330 and the bipolar plate 310 are stacked and tightly fitted with no gaps between them. The electrolyte can only enter the cavity of the cathode chamber through the cathode liquid outlet slot and the cathode liquid inlet slot.

[0071] In one possible implementation, the ion exchange membrane 500 is provided with four through holes. It should be noted here that the main body of the ion exchange membrane 500 is a rectangular plate structure, and the four through holes are respectively located at the four corners of the ion exchange membrane 500. The anode electrolyte inlet channel, the anode electrolyte gas-liquid outlet channel, the cathode electrolyte inlet channel, and the cathode electrolyte gas-liquid outlet channel are respectively connected to the four through holes on the ion exchange membrane 500.

[0072] In one possible implementation, bolts are also included. The first end plate 110 has more than two bolt holes 115, and correspondingly, the second end plate 120 has more than two bolt holes (not shown in the figure). The bolts pass through the bolt holes 115 of the first end plate 110 and the bolt holes of the second end plate 120 in sequence. Nuts are provided at both ends of the bolts. By tightening the nuts on both sides of the bolts, the anode electrolysis chamber, ion exchange membrane 500 and cathode electrolysis chamber located between the first end plate 110 and the second end plate 120 are fastened.

[0073] It should be noted here that the length and width of the first end plate 110 and the second end plate 120 are respectively larger than the length and width of the terminal plate 210, the first sealing gasket 220, the first flow channel plate frame 240 and the second sealing gasket 230, the ion exchange membrane 500, the third sealing gasket 320, the second flow channel plate frame 340, the fourth sealing gasket 330 and the bipolar plate 310. Therefore, the bolts do not need to pass through the anode electrolyte chamber, the ion exchange membrane 500 and the cathode electrode chamber to achieve the clamping of the anode electrolyte chamber, the ion exchange membrane 500 and the cathode electrode chamber located between the first end plate 110 and the second end plate 120.
