Description

Technical Field

[0002] Sodium hypochlorite generator is a type of water treatment disinfection and sterilization equipment. The equipment uses salt water as raw material and produces sodium hypochlorite solution through electrolysis reaction.

[0003] Electric current passes through the brine in the electrolytic cell, thereby inducing different chemical reactions at the anode and cathode. The cathode electrode sheet and the anode electrode sheet of the electrode sheet group in the electrolytic cell will produce gas during the electrolysis process with the electrolyte, and the gas will form bubbles in the electrolyte and rise with the flow of the electrolyte. During the rising process of the bubbles, the bubbles will contact the cathode electrode sheet or the anode electrode sheet of the electrode sheet group. When the bubbles contact the cathode electrode sheet or the anode electrode sheet, the contact area of ​​the cathode electrode sheet or the anode electrode sheet will be reduced, thereby reducing its electrolysis efficiency.

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual Figures 1 to 3A sodium hypochlorite generator comprises: a softened water tank 2, a molten salt tank 3, an electrolytic cell 1 and a storage tank 4, wherein the softened water tank 2, the molten salt tank 3, the electrolytic cell 1 and the storage tank 4 are sequentially connected, the softened water enters the molten salt tank 3 through the softened water tank 2, and is mixed with the molten salt to form an electrolyte, and then the electrolyte is electrolyzed in the electrolytic cell 1 to form a sodium hypochlorite solution, and the sodium hypochlorite solution is collected by the storage tank 4;

[0037] An electrode sheet group 11 is arranged in the electrolytic cell 1. The electrode sheet group 11 includes a plurality of anode electrode sheets and anode electrode sheets that are evenly arranged and distributed. The electrode sheet group 11 is separated into a plurality of gaps 12 in the vertical direction.

[0038] The electrolytic cell 1 is provided with a flushing mechanism, which includes a liquid extraction component, which is used to extract the electrolyte in the electrolytic cell 1 and flush it horizontally at the gap 12 to flush the bubbles generated during the electrolysis process to the side of the electrolytic cell 1.

[0039] It should be noted that a group of flushing mechanisms are provided at each of the multiple gaps 12. The liquid extraction component may be a water pump. The water pump extracts the electrolyte in the electrolytic cell 1 and discharges the electrolyte back into the electrolytic cell 1 through the water pump. At the same time, the electrolyte discharged back into the electrolytic cell 1 is flushed laterally at the gaps 12, flushing the bubbles generated by electrolysis toward the sides of the electrolytic cell 1.

[0040] The specific implementation scenario is as follows: softened water is passed from the softened water tank 2 into the molten salt tank 3 through a water pump, the softened water is mixed with the molten salt to form an electrolyte, and then the electrolyte is passed into the electrolytic cell 1 for electrolysis to generate a sodium hypochlorite solution. Since gas is generated during the electrolysis process, the gas forms bubbles in the electrolyte and rises with the flow of the electrolyte. During the rising process of the bubbles, the bubbles come into contact with the cathode electrode sheet or the anode electrode sheet of the electrode sheet group 11. When the bubbles come into contact with the cathode electrode sheet or the anode electrode sheet, the contact area of ​​the cathode electrode sheet or the anode electrode sheet is reduced, thereby reducing the electrolysis efficiency. However, the electrolysis During the process, the bubbles move over a long distance in the electrode sheet group 11. At the same time, the electrolyte in the electrolytic cell 1 is extracted by a water pump, and the electrolyte is discharged back into the electrolytic cell 1 by the water pump. At the same time, the electrolyte discharged back into the electrolytic cell 1 is horizontally flushed at the gap 12, and the bubbles generated by electrolysis are flushed to the side of the electrolytic cell 1. This can shorten the movement distance of the bubbles in the electrode sheet group 11 in contact with the cathode electrode sheet or the anode electrode sheet, so that the bubbles only flow in a short distance, avoiding long-distance flow of the bubbles, thereby reducing the contact area between the bubbles and the cathode electrode sheet or the anode electrode sheet during the electrolysis process, thereby improving the electrolysis efficiency.

[0041] It should also be noted that when the bubbles generated by electrolysis are flushed to the side of the electrolytic cell 1, the contact area between the bubbles and the cathode electrode sheet or the anode electrode sheet during the upward flow can be reduced, thereby increasing the contact area between the cathode electrode sheet or the anode electrode sheet and the electrolyte, thereby further improving its electrolysis efficiency.

[0042] For further information, please refer to the attached manual. Figure 3 The flushing mechanism is a flushing component 5, the liquid pumping component is a circulating pump 51, the flushing component 5 includes a liquid pumping tube 52, the liquid inlet end of the liquid pumping tube 52 is connected to the electrolytic cell 1, the liquid outlet end of the liquid pumping tube 52 is connected to the circulating pump 51, the liquid outlet end of the circulating pump 51 is connected to a liquid delivery tube 53, the liquid outlet end of the liquid delivery tube 53 extends into the electrolytic cell 1, and is connected to a nozzle 54.

[0043] It should be noted that the nozzle 54 is a flat-mouth nozzle, and the circulation pump 51 extracts the electrolyte in the electrolytic cell 1 through the liquid extraction pipe 52, and discharges the electrolyte back to the electrolytic cell 1 through the liquid delivery pipe 53. At the same time, the electrolyte discharged into the electrolytic cell 1 is horizontally flushed toward the gap 12 through the flat-mouth nozzle. During the gradual rising process of the bubbles after they are generated, the bubbles are flushed toward the side of the electrolytic cell 1 by the flushing of the electrolyte, thereby shortening the movement stroke of the bubbles in the electrode sheet group 11 in contact with the cathode electrode sheet or the anode electrode sheet, thereby reducing the contact area between the bubbles and the cathode electrode sheet or the anode electrode sheet during the electrolysis process, so that the electrolysis efficiency can be improved.

[0044] In the above technical scheme, the bubbles are flushed to the side of the electrolytic cell 1 by the flushing force of the electrolyte. However, after the bubbles are flushed to the side of the electrolytic cell 1, the electrolyte will be flushed on the inner wall of the electrolytic cell 1, resulting in the problem of the electrolyte driving the bubbles to flow back. In order to avoid the situation where the bubbles flow back to the electrode sheet group 11, the present invention also provides a barrier component 6 to prevent the electrolyte from driving the bubbles to flow back to the electrode sheet group 11.

[0045] For details, please refer to the attached manual. Figure 3 and Figure 4 A barrier component 6 is also provided in the electrolytic cell 1. The barrier component 6 includes a plurality of partitions 61. The plurality of partitions 61 are fixedly arranged in the electrolytic cell 1, and the spacing distance between two adjacent partitions 61 in the vertical direction corresponds to the separation gap 12 of the electrode sheet group 11 in the vertical direction, so that after the bubbles are flushed to the side of the electrolytic cell 1, the bubbles are blocked, so that the bubbles always move on the side of the electrolytic cell 1.

[0046] It should be noted that by arranging a plurality of partitions 61 in the electrolytic cell 1 , when bubbles are driven by the electrolyte to flow back, the partitions 61 block the bubbles to prevent the bubbles from flowing back into the electrode sheet group 11 .

[0047] In the above technical scheme, the bubbles are flushed to the side of the electrolytic cell 1 by the flushing force of the electrolyte, and the bubbles are blocked by the partition 61 to prevent the bubbles from flowing back into the electrode sheet group 11. However, the electrolyte is always in a state of flowing from bottom to top in the electrolytic cell 1. When the electrolyte drives the bubbles to flow back, although the bubbles are blocked by the partition 61, there is still a problem that the bubbles are brought into the electrode sheet group 11 during the upward flow of the electrolyte. For this reason, the present invention proposes a flushing and exhaust component 7, which is used to directly take away and discharge the bubbles after flushing them to the side of the electrolytic cell 1.

[0048] For details, please refer to the attached manual. Figure 5 The flushing mechanism is a flushing exhaust component 7, and the liquid extraction component is a circulating pump 2 71. The flushing exhaust component 7 extracts electrolyte through the circulating pump 2 71, so that the electrolyte is flushed horizontally at the gap 12, and the bubbles generated during the electrolysis process are flushed to the side of the electrolytic cell 1, and the bubbles are discharged from the electrolytic cell 1.

[0049] For further information, please refer to the attached manual. Figure 5 The flushing and exhaust assembly 7 includes a second liquid extraction pipe 72, the liquid inlet end of the second circulating pump 71 is connected to the second liquid extraction pipe 72, the liquid inlet end of the second liquid extraction pipe 72 is connected to the electrolytic cell 1, the liquid outlet end of the second circulating pump 71 is connected to a second liquid delivery pipe 73, the liquid delivery pipe 73 is provided with an exhaust assembly 74, the liquid outlet end of the second liquid delivery pipe 73 extends into the electrolytic cell 1 and is connected to a second nozzle 75, and the liquid outlet end of the second nozzle 75 is aligned with the liquid inlet end of the second liquid extraction pipe 72 in the horizontal direction.

[0050] It should be noted that nozzle 2 75 is a flat-mouth nozzle, and circulating pump 2 71 extracts electrolyte in electrolytic cell 1 through liquid extraction pipe 2 72, and discharges the electrolyte back into electrolytic cell 1 through liquid delivery pipe 2 73. At the same time, the electrolyte is ejected through the flat-mouth nozzle, and the electrolyte is driven to be flushed horizontally toward gap 12 through the flat-mouth nozzle. During the gradual rising process of bubbles after generation, the bubbles are flushed toward the side of electrolytic cell 1 through the flushing of electrolyte. At the same time, liquid extraction pipe 2 72 continues to circulate the electrolyte with bubbles, so that the bubbles in the electrolyte can be discharged through the exhaust component 74.

[0051] For further information, please refer to the attached manual. Figure 6The exhaust component 74 includes an exhaust bucket 741, which is connected to the liquid delivery pipe 73. A hinged rod 742 is hinged in the exhaust bucket 741, and a float 743 is connected to the end of the hinged rod 742. A push rod 744 is slidably arranged in the exhaust bucket 741, and the end of the push rod 744 is in contact with the hinged rod 742. An exhaust hole 745 is opened on the exhaust bucket 741, and a sealing ring 746 is arranged at the air inlet end of the exhaust hole 745. When the liquid level in the exhaust bucket 741 rises, the float 743 rises with the rise of the liquid level until the float 743 contacts and seals with the sealing ring 746. When the liquid level in the exhaust bucket 741 drops, the float 743 drops with the drop of the liquid level, the float 743 is separated from the sealing ring 746, and the gas is discharged from the exhaust hole 745.

[0052] It should be noted that when the electrolyte enters the exhaust hopper 741, the liquid level in the exhaust hopper 741 rises. At the same time, since the density of the gas is less than the density of the electrolyte, the gas will rise first and be discharged through the exhaust hole 745. When the liquid level in the exhaust hopper 741 rises to the point where the float 743 contacts and seals the sealing ring 746, the gas cannot be discharged. At this time, since the density of the gas is less than the density of the electrolyte, the gas will exist in the upper half of the exhaust hopper 741. When the gas increases, the liquid level in the exhaust hopper 741 will gradually drop, so that the float 743 can drop as the liquid level drops, and the gas can be discharged from the exhaust hole 745. This cycle can be repeated to discharge the gas generated by electrolysis.

[0053] It should also be noted that the gases produced during the electrolysis process are mainly chlorine and hydrogen. Chlorine is a harmful gas, and if the concentration of hydrogen is high, it is easy to cause the risk of explosion. Therefore, when the gas is discharged, it is necessary to further process the exhaust gas before discharging it.

[0054] In the above technical scheme, since an exothermic reaction will occur during the electrolysis process and the heat release will cause the electrolyte temperature to rise, the bubbles will grow larger due to the effect of thermal expansion and contraction. Although the present application shortens the movement stroke of the bubbles in the electrode sheet group 11 in contact with the cathode electrode sheet or the anode electrode sheet, if the bubbles are large, there will still be a problem of affecting the electrolysis efficiency within this shorter stroke. For this reason, the present invention proposes a cooling mechanism 8 for cooling the electrolyte during the electrolysis process so that the bubbles can be reduced in size under the effect of thermal expansion and contraction to improve the electrolysis efficiency.

[0055] For details, please refer to the attached manual. Figure 7 The electrolytic cell 1 is also provided with a cooling mechanism 8, which is used to cool the electrolyte during the electrolysis process.

[0056] For further information, please refer to the attached manual. Figure 7The cooling mechanism 8 includes a plurality of heat exchange sleeves 81, which are fixedly mounted on the electrolytic cell 1, and a heat exchange hole 82 is arranged in each of the heat exchange sleeves 81. A connecting pipe 83 is connected to each of the heat exchange sleeves 81, and the heat exchange sleeves 81 are connected to the heat exchange holes 82 in sequence through the connecting pipes 83 in the vertical direction.

[0057] It should be noted that the heat exchange holes 82 are spirally arranged, and the coolant is introduced into the heat exchange holes 82 through the connecting pipe 83. Under the action of the connecting pipe 83, the coolant can flow in several heat exchange holes 82, which can achieve the effect of heat exchange cooling of the electrolyte during the electrolysis process, so that the electrolyte can be cooled and the bubbles can be reduced under the action of thermal expansion and contraction, thereby improving the electrolysis efficiency.

[0058] For further information, please refer to the attached manual. Figure 8 The liquid inlet end of the heat exchange jacket 81 located at the bottom is connected to a circulation pump 3 84, and the liquid inlet end of the circulation pump 3 84 is connected to a coolant tank 85. The heat exchange jacket 81 located at the top is connected to a heat exchanger 86, and the heat exchanger 86 and the coolant tank 85 are connected through a pipeline.

[0059] It should be noted that the coolant in the coolant tank 85 is drawn by the circulation pump 84 and passed into the heat exchange hole 82 of the heat exchange sleeve 81, so that the coolant can flow in the heat exchange hole 82 to achieve the effect of heat exchange cooling. The coolant heated by heat exchange can enter the heat exchanger 86 through the pipeline to cool the heated coolant, and then the cooled coolant is sent to the coolant tank 85 through the pipeline to facilitate the circulation heat exchange cooling of the electrolyte.

[0060] It should also be noted that the liquid inlet and outlet of the heat exchanger 86 can be connected to the pipeline through a circulation pump to facilitate the circulation of the coolant.

[0061] Refer to the instruction manual Fig. 9 , a method for using a sodium hypochlorite generator, comprising the following steps:

[0062] Step 1: Pass softened water into the molten salt tank 3 through the softened water tank 2 to mix the softened water with the molten salt to form an electrolyte, and then pass the electrolyte into the electrolytic cell 1 for electrolysis to generate a sodium hypochlorite solution;

[0063] Step 2: The bubbles generated by electrolysis are flushed toward the side of the electrolytic cell 1 by a flushing mechanism, and the bubble backflow is prevented by a barrier component 6;

[0064] Step 3: During the electrolysis process, the temperature of the electrolysis process is lowered by the cooling mechanism 8, so that the bubbles generated by the electrolysis shrink due to thermal expansion and contraction;

[0065] Step 4: After the electrolysis is completed, the sodium hypochlorite solution produced by the electrolysis is passed into the storage tank 4 for storage.

[0066] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
