Description

Technical Field

[0001] The present invention relates to the technical field of sodium hypochlorite production, and in particular to a generator and an electrolysis method for improving the electrolysis efficiency of sodium hypochlorite. Background Art

[0002] In the process of preparing sodium hypochlorite by hypochlorous acid generator, salt water needs to be electrolyzed. The electrolytic electrodes are made of special anti-corrosion precious metal materials. Since the electrolysis voltage is only tens of volts, the gap between the electrode fins must be very small to effectively perform electrolysis. Multiple positive and negative electrode sheets are stacked together, and the electrodes are heavy. When placed in the electrolytic cell, several electrode insulating supports are required. The insulating supports are generally round, and the internal matching electrode shape is square. In order to smoothly place the electrodes in the electrolytic cell, the insulating supports are generally 2~3 mm smaller than the inner diameter of the electrolytic cell. The salt water can only be effectively electrolyzed if it passes through the gap between the electrode fins. The total reaction in the electrolytic cell is expressed as follows:

[0003] NaCl + H2O → NaClO + H2↑

[0004] The groove on the upper part of the insulating support is a channel for the generated gas to be discharged, and finally it is discharged into the hyposodium storage tank together with the generated hyposodium disinfectant.

[0005] Limitations and shortcomings:

[0006] 1. The salt water electrolyte can penetrate through the gaps around the insulating support and the inner wall of the electrolytic cell, reducing the electrolysis efficiency of the electrolyte;

[0007] 2. The gas-water mixture flows through the hydrogen discharge groove, which also reduces the electrolysis efficiency;

[0008] 3. Hydrogen and disinfectant enter the liquid storage tank together. A large amount of electrolytic hydrogen accumulates at the top of the tank, which is difficult to discharge in time and poses a safety hazard.

[0009] Therefore, it is necessary to propose a generator and electrolysis method for improving the electrolysis efficiency of sodium hypochlorite to separate and collect the gas after electrolysis from the sodium hypochlorite disinfectant, thereby improving safety performance and also improving electrolysis efficiency.

[0039] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0040] Please refer to Figures 1-6 The present invention proposes a generator for improving the electrolysis efficiency of sodium hypochlorite, comprising a shell 1, an electrode assembly 2, a first insulating support 3, and a second insulating support 4. A receiving tank 11 is provided in the shell 1, and the receiving tank 11 is a cylindrical structure. The first insulating support 3 and the second insulating support 4 are both sleeved on the surface of the electrode assembly 2 and the electrode assembly 2 is fixedly placed in the receiving tank 11. The two ends of the electrode assembly 2 are respectively electrically connected to the two ends of the shell 1 for positive and negative electrodes. The two ends of the shell 1 are respectively provided with a positive electrode connection end and a negative electrode connection end. The outer walls of the first insulating support 3 and the second insulating support 4 are tightly connected to the wall of the receiving tank 11. The first insulating support 3 divides the receiving tank 11 into an electrolytic cell 111 and a collecting tank 112. The second insulating support 3 is provided with a positive electrode connection end. The insulating support 4 is housed in the electrolytic cell 111, and the shell 1 is provided with a liquid inlet 12, a liquid discharge port 13, and a liquid-blocking exhaust port 14. The liquid inlet 12 and the liquid-blocking exhaust port 14 are both connected to the electrolytic cell 111, and the liquid-blocking exhaust port 14 has a water seal function. The liquid-blocking exhaust port 14 can be adjusted according to demand to release the pressure of the gas in the electrolytic cell 111, that is, it can maintain the gas in the electrolytic cell 111 within a preset pressure value. The liquid discharge port 13 is connected to the collecting tank 11, and the electrolyte flows into the collecting tank 11 through the electrode assembly 2. The first insulating support 3 and the second insulating support 4 are similar in shape, both are round cakes, but one side of the second insulating support 4 has a transparent structure, which allows the electrolyzed gas to flow freely above the electrolytic cell 111.

[0041] In this embodiment, the electrode assembly 2 is mounted in the receiving tank 11 by using the first insulating support 3 and the second insulating support 4, so that the electrode assembly 2 can be in full contact with the electrolyte. The receiving tank 11 is divided into the electrolytic tank 111 and the collecting tank 112 by the first insulating support 3. The electrolytic tank 111 and the collecting tank 112 collect gas and hyposodium disinfectant respectively. During electrolysis, hydrogen is generated in the electrolytic tank 111, and the hydrogen is discharged to the outside through the liquid-blocking exhaust port 14. At the same time, the liquid-blocking exhaust port 14 can keep the gas in the electrolytic tank 111 at a constant pressure, so that the electrolyte is always maintained at a height that submerges the electrode assembly 2 under the action of pressure, so that the electrolyte can always be electrolyzed with the maximum contact area, avoiding the situation where the top of the electrode assembly 2 is exposed to the liquid surface during the electrolysis process, thereby improving the electrolysis efficiency. Moreover, the hyposodium disinfectant generated after electrolysis enters the collecting tank 112 through the gap of the electrode assembly 2, and is then discharged to the outside from the drain port 13, thereby realizing gas-liquid separation and collection, and improving safety performance.

[0042] In this embodiment, the first insulating support member 3 includes a first insulating support plate 31 and a sealing ring 32. The first insulating support plate 31 is sleeved on the outer peripheral side of the electrode assembly 2, and the sealing ring 32 is sleeved on the outer peripheral side of the first insulating support plate 31. The outer peripheral side of the sealing ring 32 is tightly connected to the groove wall of the receiving groove 11. Before using the first insulating support member 3, the sealing ring 32 needs to be installed in the groove on the outer peripheral side of the first insulating support plate 31. The first insulating support plate 31 has a circular pancake-shaped structure. A square groove is provided in the middle of the first insulating support plate 31, and the electrode assembly 2 passes through the square groove. Before inserting the electrode assembly 2 into the receiving groove 11, the first insulating support member 3 and the second insulating support member 4 need to be installed on the electrode assembly 2. After the first insulating support member 3 and the second insulating support member 4 are installed, the electrode assembly 2 is inserted into the receiving groove 11 from right to left, so that the first insulating support member 3 finally divides the receiving groove 11 into the electrolytic cell 111 and the collecting cell 112. At this time, the installation of the electrode assembly 2 is completed.

[0043] In this embodiment, there are multiple second insulating support members 4, and the multiple second insulating support members 4 are arranged in sequence and are all mounted on the electrode assembly 2. The multiple second insulating support members 4 are interconnected in the electrolytic cell 111; there are a total of 3 second insulating support members 4, which are used to provide balanced support for the electrode assembly 2 so that the electrode assembly 2 can be placed stably in the storage tank 11.

[0044] In this embodiment, the second insulating support member 4 includes a second insulating support plate 41 and a sealing strip 42. The second insulating support plate 41 is sleeved on the outer peripheral side of the electrode assembly 2. The sealing strip 42 is fixed around the outer peripheral side of the second insulating support plate 41. The outer peripheral side of the sealing strip 42 is tightly connected to the groove wall of the receiving groove 11. A through groove 411 is provided on one side of the second insulating support plate 41. The through groove 411 allows multiple second insulating supports 4 to be connected to each other in the electrolytic cell 111. The sealing strip 42 is connected along the second insulating support plate 41 by an adhesive. When the second insulating support 4 is installed on the electrode assembly 2, the through grooves 411 need to be set upward, that is, the through grooves 411 of the three second insulating supports 4 are all facing upward. The function of the through grooves 411 is to allow the gas generated during electrolysis to flow through the top of the electrolytic cell 111, thereby flowing out of the outside through the liquid-blocking exhaust port 14. At the same time, the gas in the electrolytic cell 111 can also form a constant pressure on the liquid in the electrolytic cell 111, thereby maintaining the electrolyte at a height at which the electrode assembly 2 is immersed.

[0045] In this embodiment, an exhaust water seal 141 is provided on the liquid-blocking exhaust port 14. The exhaust water seal 141 is fixedly connected to and communicated with the liquid-blocking exhaust port 14. The exhaust water seal 141 is used to exhaust gas and prevent the electrolyte from flowing out of the liquid-blocking exhaust port 14. The exhaust water seal 141 can maintain the gas pressure in the electrolytic cell 111. The exhaust water seal 141 is an existing device, which is used to discharge gas and prevent liquid from flowing out. At the same time, the pressure of the released gas can be adjusted according to the situation to maintain the gas in the electrolytic cell 111 within a preset pressure value.

[0046] In this embodiment, the electrode assembly 2 includes a stacked electrode member 21 and a gas barrier member 22. The stacked electrode member 21 is composed of multiple positive and negative electrodes stacked together with a gap. The stacked electrode member 21 is provided with an extension section 211, a connecting portion 212, and an electrolysis section 213. The extension section 211, the connecting portion 212, and the electrolysis section 213 are arranged in sequence and fixedly connected end to end. The two ends of the electrolysis section 213 are respectively electrically connected to the two ends of the shell 1 for positive and negative electrodes. The extension section 211 is accommodated in the collecting tank 112, and the connecting portion 212 and the electrolysis section 213 are both accommodated in the electrolytic cell 111. There are two gas barriers 22, which are respectively located on the left and right sides of the connecting portion 212. The gas barrier 22 and the connecting portion 212 form a detachable connection. The detachable connection can facilitate the regular replacement of the gas barrier 22. The gas barrier 22 is a strip-shaped compressed cotton-like object that can block bubbles. The gas barrier 22 forms liquid conduction and gas barrier between the electrolysis section 213 and the extension section 211; when the electrode assembly 2 electrolyzes the electrolyte, the electrolysis section 213 is energized for electrolysis, that is, the electrolysis section 213 electrolyzes the electrolyte in the electrolytic cell 111. During the electrolysis process, bubbles are generated on the surface of the electrolysis section 213. Since the electrolyte flows in from the liquid inlet 12, and the hyposodium disinfectant generated after electrolysis flows out from the drain port 13, the liquid in the electrolytic cell 111 will flow toward the collection tank 112. During the flow, it is easy to drive the bubbles to flow into the collection tank 112, and then the drain port 13 is also mixed with bubbles. The gas barrier 22 is arranged between the electrolysis section 213 and the extension section 211, which can block the bubbles, so that the hyposodium disinfectant flowing into the collection tank 112 does not contain bubbles, thereby improving the collection purity of the hyposodium disinfectant.

[0047] In this embodiment, the connecting portion 212 is provided with an insertion groove 2121, which is respectively connected to the extension section 211 and the electrolysis section 213. The gas barrier 22 is accommodated in the insertion groove 2121, and the gas barrier 22 fills the insertion groove 2121; the insertion groove 2121 is used to provide an installation space for the gas barrier 22 to block the gas between the extension section 211 and the electrolysis section 213.

[0048] In this embodiment, an elastic barrier 2122 is provided at the top of the connecting portion 212. The elastic barrier 2122 is arranged horizontally and extends to the top of the insertion groove 2121. The elastic barrier 2122 partially blocks the top of the gas barrier 22. Before installing the gas barrier 22, it is necessary to manually pry the elastic barrier 2122 apart backwards, and then insert the gas barrier 22 into the insertion groove 2121, and then release the elastic barrier 2122. At this time, the elastic barrier 2122 blocks the top of the gas barrier 22, and the installation of the gas barrier 22 is completed.

[0049] In this embodiment, the elastic barrier 2122 includes a barrier plate 21221 and an elastic member 21222. A mounting groove 2123 is provided on the top of the connecting portion 212. The barrier plate 21221 is slidably connected to the mounting groove 2123 and extends to the top of the insertion groove 2121. One end of the barrier plate 21221 partially blocks the top of the gas barrier 22. The elastic member 21222 is accommodated in the mounting groove 2123. One end of the elastic member 21222 is connected to the barrier. The other end of the partition 21221 is fixedly connected, and the other end of the elastic member 21222 is fixedly connected to the side wall of the mounting groove 2123; when the elastic barrier member 2122 is pried open backward, the barrier plate 21221 needs to be slid backward so that the elastic member 21222 is compressed and stores force. After the barrier plate 21221 is released, the elastic member 21222 recovers and drives the barrier plate 21221 to slide forward to partially block the top of the gas barrier member 22.

[0050] Please refer to Figure 1 、 Figure 4 、 Figure 7 , an electrolysis method for improving the electrolysis efficiency of sodium hypochlorite, according to any of the above generators for improving the electrolysis efficiency of sodium hypochlorite, comprising:

[0051] S1, introducing electrolyte into the electrolytic cell 111 at a preset rate so that the electrolyte submerges the electrode assembly 2;

[0052] S2, connecting the positive and negative electrodes of the housing 1 to electricity, so that the electrode assembly 2 is energized to electrolyze the electrolyte;

[0053] S3. During the electrolysis process, the gas generated in the electrolytic cell 111 is discharged to the outside through the liquid-blocking exhaust port 14. The hyposodium disinfectant generated by the electrolysis enters the collecting tank 112 through the gap of the electrode assembly 2, and is then discharged to the outside through the drain port 13. The liquid-blocking exhaust port 14 allows the gas in the electrolytic cell 111 to maintain a constant pressure, thereby allowing the electrolyte to always remain at a height that submerges the electrode assembly 2 under the action of pressure.

[0054] In this embodiment, the electrolyte is introduced into the electrolytic cell 111 at a preset rate so that the electrolyte submerges the electrode assembly 2; the positive and negative poles of the shell 1 are connected to electricity so that the electrode assembly 2 is energized to electrolyze the electrolyte; during the electrolysis process, the gas generated in the electrolytic cell 111 is discharged to the outside through the liquid-blocking exhaust port 14, and the hyposodium disinfectant generated by the electrolysis enters the collecting tank 112 through the gap of the electrode assembly 2, and is then discharged to the outside through the drain port 13. The liquid-blocking exhaust port 14 keeps the gas in the electrolytic cell 111 at a constant pressure, thereby allowing the electrolyte to be discharged under the action of pressure. The height at which the electrode assembly 2 is submerged is always maintained. Since the exhaust water seal 141 is the component that mainly limits the air pressure and blocks the outflow of liquid in the liquid-blocking exhaust port 14, the exhaust water seal 141 in the liquid-blocking exhaust port 14 is selected according to the height requirement of the pipeline of the liquid inlet 12, so that the pressure of the gas above the electrolytic cell 111 remains constant. The gas pressure accumulated above the electrolytic cell 111 just makes the electrolyte level about 2 cm below the through groove 411, preventing the electrolyte from flowing from the through groove 411 through the collecting tank 112 during operation without passing through the electrolysis of the electrode assembly 2.

[0055] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
