Description

Technical Field

[0001] This application belongs to the technical field of electrolyzed water, and particularly relates to a heat-resistant electrolysis module. Background Art

[0002] In the technical field of electrolyzed water, it is usually normal temperature water (the normal temperature water in the industry is generally defined as the temperature between 20°C - 25°C) that is electrolyzed. However, when using raw water with a temperature higher than normal temperature as the raw material water, the oxidation-reduction reaction will be more intense, the electrolysis efficiency will be correspondingly improved, and the target product can be produced more efficiently.

[0003] However, when electrolyzing raw water with a temperature higher than normal temperature, especially above 30°C, due to the increase in electrolysis efficiency, the temperatures of the electrodes, diaphragms, and other internal components in the electrolysis module will also increase accordingly. At the same time, as the electrode temperature rises, calcium, magnesium, etc. in the water are separated out, and substances insoluble in water such as magnesium hydroxide and calcium carbonate will be formed on the surface of the electrode plate, which is what is commonly referred to as scaling. After scaling, due to the increase in electrode resistance, the power consumption of the electrolysis module will increase, and the temperature will continue to rise accordingly; this poses a challenge to the heat resistance of the electrolysis module.

[0004] Therefore, in order to ensure the stability and safety of the electrolysis module when electrolyzing raw water with a temperature higher than normal temperature, it is urgent to solve the heat resistance problem of the electrolysis module. Utility Model Content

[0011] Preferably, the upper and lower pressing plates are respectively provided with heat dissipation holes; with such a setting, while ensuring that the upper and lower pressing plates supply power to the anode and the cathode, the heat dissipation area of the anode is increased to reduce the working temperature of the electrolysis module.

[0019] Preferably, the diaphragm is one of a perfluorosulfonic acid proton exchange membrane, a non-fluorinated polymer membrane, a ceramic diaphragm, or a composite membrane.

[0020] Preferably, the heat distortion temperature of the fastener is not lower than 60 °C; to ensure the heat resistance of the fastener.

[0021] Preferably, the fastener is one of polypropylene, polyvinylidene fluoride, polysulfone, polyphenylene ether, or polycarbonate materials.

Detailed Embodiments

[0035] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application.

[0037] As Figure 1-2 shown, in one embodiment, the heat-resistant electrolysis module provided in this application includes an electrolysis component 1, a fastener 2 that clamps around the electrolysis component, and an electrically conductive upper pressing sheet 3 and a lower pressing sheet 4 respectively arranged at the upper and lower ends of the fastener 2;

[0038] The electrolysis component 1 includes an anode 11, a diaphragm 12, and a cathode 13 that are sequentially attached together from top to bottom;

[0039] The upper pressing sheet 3 and the lower pressing sheet 4 are respectively connected to the anode 11 and the cathode 13, clamping the upper and lower ends of the electrolysis component 1;

[0040] The diaphragm 12 is a heat-resistant diaphragm;

[0041] The fastener 2 is a heat-resistant fastener.

[0042] As described in the background art, when electrolyzing high-temperature raw water (referring to raw water with a temperature exceeding 30 °C), on the one hand, since the diaphragm 12 and the fastener 2 are in more contact with the raw water, it is necessary to give priority to solving the heat resistance problems of the diaphragm 12 and the fastener 2; on the other hand, the structural form in which the fastener 2, the upper pressing sheet 3, and the lower pressing sheet 4 are in contact and arranged around and above and below the electrolysis component 1 is conducive to the heat dissipation of the electrolysis component 1.

[0043] In another embodiment, the diaphragm 12 is one of a perfluorosulfonic acid proton exchange membrane, a non-fluorinated polymer membrane, a polyphenylene sulfide (PPS) diaphragm, a ceramic diaphragm, or a composite membrane.

[0044] Among them, fluoroplastics refer to plastics made of fluororesins; since the molecular structure of fluoroplastics contains fluorine atoms, they have many excellent properties, such as excellent high temperature resistance, outstanding oil resistance, solvent resistance and wear resistance, good moisture resistance and low temperature resistance, heat and oxygen aging resistance, and strong alkali resistance.

[0045] In another embodiment, the diaphragm 12 can also be one or a combination of two or more of ethylene-propylene rubber, EVA rubber, neoprene, chlorinated polyethylene rubber, polyacrylate rubber, ethylene acrylate rubber, nitrile rubber, and fluororubber;

[0046] Ethylene-propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers. Since its main chain is composed of chemically stable saturated hydrocarbons, it has excellent aging resistance such as alkali resistance, ozone resistance, heat resistance, and weather resistance, and has good chemical resistance, electrical insulation properties, impact elasticity, low-temperature properties, low density, high fillability, hot water resistance, steam resistance, and good resilience; The temperature resistance of EVA rubber can reach about 80-100 degrees; The heat resistance of neoprene is comparable to that of nitrile rubber, with a decomposition temperature of 230-260 °C, short-term resistance to 120-150 °C, and long-term use at 80-100 °C, and it has a certain flame retardancy; Chlorinated polyethylene rubber has excellent weather resistance and heat resistance and relatively high strength; Polyacrylate rubber has excellent high-temperature resistance, heat resistance to mineral oil, hydraulic oil, weather resistance, and low-temperature properties, with a temperature range of -20 °C to +200 °C; The heat resistance of ethylene acrylate rubber is second only to silicone rubber and fluororubber; It has a 30-60 °C higher service temperature than nitrile rubber, with a maximum service temperature of 180 °C, intermittent or short-term use up to 200 °C, and no obvious change after aging in hot air at 150 °C for several years; The heat resistance of nitrile rubber is better than that of natural rubber and styrene-butadiene rubber, and it can work at a high temperature of 120 °C; Fluororubber can be used long-term at 250 °C and short-term at 300 °C; The above materials are all existing materials.

[0047] In another embodiment, to ensure the heat resistance of the fastener 2, the heat distortion temperature of the fastener 2 is not lower than 60 °C.

[0048] Specifically, in one embodiment, if the operating temperature of the electrolysis assembly 1 is below 200 °C, the fastener 2 is selected from heat-resistant materials, which can be made of one or several of polypropylene (PP), polyvinyl fluoride homopolymer (PVF), polyvinylidene chloride (PVDC), polysulfone (PSF), polyphenylene ether (PPO), or polycarbonate (PC) materials; The above materials are all existing materials, and the heat distortion temperatures of these materials are between 100-200 °C.

[0049] In another embodiment, if the operating temperature of the electrolysis assembly 1 is below 300 °C, the fastener 2 is selected from high heat-resistant materials, which can be made of one or several of polyphenylene sulfide (PPS), chlorinated polyether, polyether ether ketone (PEEK), polyarylsulfone, etc., and thermoplastic polyimide (PI), aminoplastics, epoxy resin (EP), phenolic resin (PF); the above materials are all existing materials; among them, the heat distortion temperature of PPS can reach 240 °C, the heat distortion temperature of chlorinated polyether can reach 210 °C, the heat distortion temperature of PEEK can reach 230 °C, the heat distortion temperature of polyarylsulfone can reach 280 °C, the heat distortion temperature of thermoplastic polyimide (PI) is 270 - 280 °C, the heat distortion temperature of aminoplastics is 240 °C, the heat distortion temperature of EP can reach 230 °C, and the heat distortion temperature of PF can reach 200 °C.

[0050] As Figure 4 shown, in another embodiment, heat dissipation holes 31 are respectively provided on the upper pressing sheet 3 and the lower pressing sheet 4; while ensuring that the upper pressing sheet 3 and the lower pressing sheet 4 supply power to the anode 11 and the cathode 13, by providing the heat dissipation holes 31, the contact area between the anode 11 and the cathode 13 and the raw water is increased, heat dissipation is increased, so as to reduce the operating temperature of the electrolysis module.

[0051] In another embodiment, the fastener 2 is surrounded by two parallel pressing sheet mounting parts 21 and two parallel connecting ribs 22; the pressing sheet mounting part 21 and the connecting rib 22 can be vertically arranged or arranged at a certain angle, and this embodiment does not make any restrictions; the electrolysis assembly 1 is placed in the mounting space surrounded by the fastener 2; thus arranged, on the one hand, the fastener 2 can tightly press the periphery of the electrolysis assembly 1 for better installation and fixation, and on the other hand, since the fastener 2 is in full contact with the electrolysis assembly 1, it can better absorb the heat generated by the electrolysis of the electrolysis assembly 1 and give full play to the heat-resistant characteristics of the fastener 2.

[0052] As Figure 1 、 Figure 3-4 shown, in another embodiment, mounting ribs 211 are provided on both the upper and lower surfaces of the pressing sheet mounting part 21, and the upper pressing sheet 3 and the lower pressing sheet 4 are correspondingly provided with clamping holes 32. When the upper pressing sheet and the lower pressing sheet are mounted on the fastener 2, the mounting ribs 211 are sleeved in the clamping holes 32 for better installation and positioning.

[0053] As Figure 1 and Figure 3 shown, in one embodiment, the two pressing sheet mounting parts 21 and the two connecting ribs 22 are integrally connected, that is, the fastener 2 is a "mouth"-shaped fastener; the integrally formed fastener 2 has higher structural strength.

[0054] As Figure 1-2As shown, in one embodiment, the upper pressing sheet 3 and the lower pressing sheet 4 are respectively arranged on the upper and lower surfaces of two pressing sheet mounting members 21; with such an arrangement, the upper and lower sheets 3 and the lower pressing sheet 4 can apply force evenly to tightly press the electrolysis assembly 1. In another embodiment, the upper pressing sheet 3 and the lower pressing sheet 4 are axially symmetrically arranged along the symmetry axis between the two pressing sheet mounting members 21.

[0055] As Figure 1-2 shown, in one embodiment, the heat-resistant electrolysis module provided by the present application further includes a base 5, and the lower pressing sheet 4, the fastener 2, and the upper pressing sheet 3 are sequentially installed on the base 5 through detachable connectors; the base 5 is a heat-resistant base; by providing the heat-resistant base 5, it is possible to avoid the electrolysis module coming into contact with other heat-intolerant materials during installation, thereby preventing the stability of the electrolysis module from being affected due to excessive temperature.

[0056] In one embodiment, the base 5 is made of one or several of polypropylene (PP), polyvinyl fluoride homopolymer (PVF), polyvinylidene chloride (PVDC), polysulfone (PSF), polyphenylene oxide (PPO), or polycarbonate (PC) materials; the above materials are all existing materials.

[0057] In another embodiment, the base 5 is made of one or several of polyphenylene sulfide (PPS), chlorinated polyether, polyether ether ketone (PEEK), polyarylsulfone, etc., and thermoplastic polyimide (PI), aminoplastics, epoxy resin (EP), phenolic resin (PF); the above materials are all existing materials; the material characteristics are not elaborated here.

[0058] As Figure 1-2 shown, in another embodiment, the detachable connector includes a screw and a mounting hole provided on the fastener 2, and the screw is a heat-resistant screw; since the upper pressing sheet 3 and the lower pressing sheet 4 are used to clamp the upper and lower ends of the electrolysis assembly 1, which is crucial for the stable operation of the electrode under heating conditions, the lower pressing sheet 4, the fastener 2, and the upper pressing sheet 1 are sequentially installed on the base 5 through the detachable connector formed by the screw and the mounting hole. The installation structure is simple and effective. At the same time, using heat-resistant screws can effectively avoid the influence of high temperature on the installation stability under heating conditions and increase the working life of the electrolysis module.

[0059] As Figure 1 、 Figure 3-4 shown, in one embodiment, the screws can be arranged on both sides of the clamping hole 32, that is, a total of 4 heat-resistant screws are required for installation; in another embodiment, as Figure 2 shown, the screws can be arranged on one side of the heat dissipation hole 31, that is, a total of 2 heat-resistant screws are required for installation, which can save costs. The present invention does not limit the setting position and quantity of the screws, and only provides the above two installation illustrations.

[0060] In one embodiment, the screw can be made of high-temperature resistant metal materials such as stainless steel or other alloy materials.

[0061] As Figure 2 shown, in one embodiment, two connecting ribs 22 are fixedly arranged on the base 5. After the two pressing piece mounting parts 21 are installed with the upper pressing piece 3, the lower pressing piece 4 and the electrolysis component 1, the installation positions are aligned with the two connecting ribs 22, and then the fastener 2 is fixed on the base 5 through a detachable connecting piece; with such a setting, the installation of the electrolysis component 1 is more convenient.

[0062] In the above embodiment, the heat-resistant electrolysis module can be arranged in an open water tank.

[0063] As Figure 5 shown, in another embodiment, a sealing cover 6 is connected to the base 5, and the electrolysis component 1, the fastener 2, the upper pressing piece 3 and the lower pressing piece 4 are arranged in the space formed by the enclosure of the base 5 and the sealing cover 6; the heat-resistant electrolysis module provided by this embodiment can be not arranged in an open water tank.

[0064] In another embodiment, a water-absorbing foam is filled in the space formed by the enclosure of the base 5 and the sealing cover 6, especially near the sealing cover 6; due to the large specific heat capacity of water, when the temperature of the electrolysis component 1 is high due to heat generation, it can absorb more heat to cool the electrolysis component 1; the water-absorbing foam is made of high-temperature resistant foam.

[0065] In summary of all the above embodiments, the heat-resistant electrolysis module of the present application has implemented heat-resistant treatments at the diaphragm 12, the fastener 2, the upper pressing piece 3, the lower pressing piece 4, the fixing screw, the base 5, etc., such as using heat-resistant materials or heat-resistant structures; at the same time, the heat-resistant electrolysis module of the present application is also mainly aimed at heat resistance and heat dissipation in terms of its structural composition; the heat-resistant electrolysis module of the present application can effectively face the heat-resistant challenges when electrolyzing high-temperature raw water (referring to raw water with a temperature exceeding 30 °C).

[0066] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, several improvements and refinements can be made without departing from the principle of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
