Description

Technical Field

[0002] Currently, in the electrolysis module used for electrolyzing water, a diaphragm is mainly used to form an electrolysis component with the cathode and anode, and the electrolysis component is used to electrolyze water to produce oxidation products or reduction products. However, the electrodes in the electrolysis module are very prone to brittle cracking during use. The main reasons are as follows: 1. The structural design of the electrolytic cell, for example, the connecting piece between the electrodes will exert a force on the electrode, and this external force may cause the electrode to crack; 2. The inlet water pressure of the electrolytic cell is relatively high; 3. Some electrode materials, such as diamond film electrode materials, are affected by temperature and humidity changes, and temperature difference stress or thermal stress will occur, resulting in cracks inside the silicon wafer, and finally the entire silicon wafer will crack, making the electrode material useless for continued use; 4. Due to the insufficient strength and toughness of the electrode material itself, especially the current carbon material electrodes (including graphite, carbon fiber, carbon materials, etc.).

[0034] In order to enable those skilled in the art to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0036] As Figures 1-3 shown, in one embodiment, this application provides an electrolysis device, including an electrolysis component and a housing: the electrolysis component includes a first electrode 4, a second electrode 6, and a diaphragm 5 disposed between the first electrode 4 and the second electrode 6; the housing includes an upper cover 1 and a lower cover 8, which are arranged around the electrolysis component, and the electrolysis component and the upper cover 1 and the lower cover 8 together enclose two upper and lower cavities; at least in one cavity, a reinforcement member 2 is abutted and arranged between the housing and the electrolysis component.

[0037] By providing the reinforcement member 2 between the upper cover 1 and the electrode, support is provided to the electrode, the impact of water pressure or external pressure on the electrode is alleviated, and damage to the electrode is avoided; it should be noted that the number of the reinforcement members 2 is determined according to the actual situation. As Figure 2 、 Figure 3 shown, if both the first electrode 4 and the second electrode 6 adopt easily damaged electrodes such as diamond film electrodes or carbon material electrodes, the reinforcement member 2 should be provided between the first electrode 4 and the upper cover 1, and the reinforcement member 2 should also be provided between the second electrode 6 and the lower cover 8; as Figure 1As shown, when one of the first electrode 4 and the second electrode 6 uses an easily damaged electrode such as a diamond film electrode or a carbon material electrode (usually the electrode connected to the positive pole of the power supply. Since the electrode connected to the positive pole of the power supply needs to consider the electrolysis rate and quality factors, an electrode with higher electrolysis efficiency such as a diamond film electrode or a carbon material electrode is usually selected, while the electrode connected to the negative pole of the power supply can use other electrodes with stronger materials), only a reinforcement member 2 needs to be provided at this electrode.

[0038] In another embodiment, the reinforcement member 2 is a shock-absorbing reinforcement member. Specifically, the reinforcement member 2 can be in the form of a grid plate or a rubber pad, a washer, etc. with a buffering effect; while providing support for the electrode, the shock-absorbing reinforcement member can also provide a buffering effect to further relieve the impact of water pressure or external pressure on the electrode. Specifically, the attached drawings provided in this application show the case where the grid plate is used as the shock-absorbing reinforcement member. The grid-shaped reinforcement member 2 can also dissipate heat and reduce the impact force of water pressure. The grid shape, size, and quantity of the grid plate are not limited in this embodiment.

[0039] In another embodiment, a conductive sheet 3 is provided between the reinforcement member 2 and the housing. In this embodiment, the reinforcement member 2 is made of a conductive material. The external power supply is connected to the conductive sheet 3, and then connected to the electrode through the conductive reinforcement member 2 to provide power for the electrolysis assembly.

[0040] In another embodiment, a conductive sheet 3 is provided between the reinforcement member 2 and the electrolysis assembly. In this embodiment, the reinforcement member 2 can be made of a conductive material or an insulating material. The external power supply is connected to the conductive sheet 3 and then to the electrode to provide power for the electrolysis assembly.

[0041] In another embodiment, the housing further includes a fastening clip 7. The electrolysis assembly is fastened on the fastening clip 7, and the upper cover 1 and the lower cover 8 are surrounded on the upper and lower sides of the electrolysis assembly through the fastening clip 7. That is, on the one hand, the fastening clip 7 provided in this embodiment can play a role in fixing the electrolysis assembly, and on the other hand, it can also connect the upper cover 1 and the lower cover 8 so that the upper cover 1 and the lower cover 8 surround to form a closed space, and this closed space is divided into two upper and lower cavities by the electrolysis assembly; it should be noted that the electrolysis assembly can be fixedly connected to the fastening clip 7 or detachably connected to the fastening clip 7, such as snap connection, etc.; for the convenience of maintenance and replacement of the electrolysis assembly, it is preferably that the electrolysis assembly is detachably connected to the fastening clip 7.

[0042] In another embodiment, the upper cover 1 and the lower cover 8 are detachably connected by a magnetic attraction method and are surrounded on the upper and lower sides of the electrolysis assembly; the upper cover 1 and the lower cover 8 are connected by a magnetic attraction method, which is more convenient for disassembly.

[0043] In another embodiment, the thickness of the first electrode 4 and / or the second electrode 6 is at least 0.1 mm. Through a large number of experimental data verification in this embodiment, when the thickness of the electrode is less than 0.1 mm, the electrode is more likely to break. Therefore, in this embodiment, it is preferably to set the thicknesses of both the first electrode 4 and the second electrode 6 to be greater than or equal to 0.1 mm.

[0044] In another embodiment, the electrode connected to the positive pole of the power supply is an electrode with a coating. Specifically, the coating can be a polyurea coating; the coating can reduce the temperature difference stress and thermal stress of the electrode, and can further prevent the electrode from breaking.

[0045] As Figures 1-3 shown, in all embodiments, the diaphragm 5 and the upper cover 1 enclose a cavity, and the diaphragm 5 and the lower cover 8 enclose a cavity; further, the housing is also provided with a water inlet 10 and a water outlet 9 that are respectively communicated with the two cavities; in one embodiment, if the first electrode 4 is externally connected to the positive pole of the power supply, the cavity enclosed by the diaphragm 5 and the upper cover 1 is the positive electrode cavity, and the cavity enclosed by the diaphragm 5 and the lower cover 8 is the negative electrode cavity. At this time, the water inlet 10 is communicated with the upper cover 1, and the water outlet 9 is communicated with the lower cover 8. The electrolytic raw water enters the positive electrode cavity from the water inlet 10, and after being electrolyzed by the electrolysis assembly, it enters the negative electrode cavity and then is discharged from the water outlet 9. In other embodiments, if the first electrode 4 is externally connected to the negative pole of the power supply, the cavity enclosed by the diaphragm 5 and the upper cover 1 is the negative electrode cavity, and the cavity enclosed by the diaphragm 5 and the lower cover 8 is the positive electrode cavity. At this time, the water inlet 10 is communicated with the lower cover 8, and the water outlet 9 is communicated with the upper cover 1. The electrolytic raw water enters the positive electrode cavity from the water inlet 10, and after being electrolyzed by the electrolysis assembly, it enters the negative electrode cavity and then is discharged from the water outlet 9 (not shown in the figure); this application does not limit the positive and negative poles of the power supply externally connected to the first electrode 4; if the first electrode 4 is connected to the positive pole, the second electrode 6 is connected to the negative pole; if the first electrode 4 is connected to the negative pole, the second electrode 6 is connected to the positive pole, and the positions of the water inlet 10 and the water outlet 9 can be adjusted correspondingly.

[0046] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present application.
