Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, specifically to a high-efficiency electrolytic cell based on a silica catalyst carrier. Background Technology

[0002] An electrolytic cell includes an anode (positive electrode), a cathode (negative electrode), and an electrolyte. When the voltage applied by an external power source exceeds the decomposition voltage in the electrolyte, current flows through the electrolyte, and redox reactions occur at the anode and cathode, respectively.

[0003] However, the traditional electrode materials used in existing electrolyzers may not have optimal catalytic activity or stability, resulting in slow reaction rates or short lifespans, which increases the cost of long-term operation. Furthermore, if the heat generated during the electrolysis process is not effectively managed, it can lead to localized overheating, affecting the physical properties of the electrolyte (such as viscosity and conductivity), thereby reducing overall efficiency.

[0004] This necessitates a high-efficiency electrolyzer based on a silica catalyst support. Utility Model Content

[0005] The technical problem to be solved by this invention is the low reaction efficiency, and a high-efficiency electrolyzer based on a silica catalyst support is provided.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a high-efficiency electrolyzer based on a silica catalyst support, including an electrolyzer body, an anode assembly, a cathode assembly, and a silica catalyst support, and also including a temperature control mechanism;

[0007] The main body of the electrolytic cell has a space to contain the electrolyte. An inlet pipe is set at the center of the bottom of the main body of the electrolytic cell. The anode assembly and the cathode assembly are respectively installed at both ends of the main body of the electrolytic cell and are electrically connected to an external power source. A silica-based catalyst carrier is set on the anode assembly and the cathode assembly to improve the efficiency of the electrochemical reaction.

[0008] The temperature control mechanism includes a temperature control housing, which is detachably installed on the main body of the electrolytic cell and arranged around the main body of the electrolytic cell. The temperature control components are located inside the temperature control housing and are used to control the electrolysis temperature.

[0009] As an improvement, the anode and cathode assemblies are detachably connected to both ends of the electrolytic cell body. After being embedded in the mounting plate, the anode and cathode assemblies are placed facing the inside of the electrolytic cell body and connected to the outer wall of the electrolytic cell body by bolts passing through the mounting plate.

[0010] As an improvement, the temperature control housing includes a mounting sleeve and a cover plate;

[0011] After one end of the installation cylinder is open, it is sealed with a cover plate. After the main body of the electrolytic cell is placed inside the installation cylinder, the cover plate closes the open end of the installation cylinder. The installation cylinder has a slot that matches the main body of the electrolytic cell.

[0012] As an improvement, the cover plate is provided with an extension plate that extends into the slot. After the bolt passes through the pre-set through hole on the cover plate, it engages with the threaded hole on the mounting cylinder for threaded connection.

[0013] As an improvement, the temperature control component includes a heating plate and cooling pipes;

[0014] The heating plates are installed on the inner wall of the mounting cylinder, and there is a pair of them arranged in a mirror image. The cooling pipes are installed on the inner wall of the mounting cylinder and are located between the two heating plates. A temperature controller is installed on the outer wall of the mounting cylinder to cooperate with the heating plates and the cooling pipes. The temperature controller is electrically connected to the temperature sensor inside the mounting cylinder.

[0015] As an improvement, a diaphragm is also included, which is fixedly installed inside the electrolytic cell body and positioned between the anode assembly and the cathode assembly to separate the anode and cathode regions.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. By using silica as a catalyst support and optimizing its pore structure and surface properties, the dispersion of the catalyst and the number of active sites are improved, thereby enhancing the electrochemical reaction rate.

[0018] 2. By integrating the heating plate and cooling pipes into a temperature control mechanism, precise temperature control of the electrolysis process is achieved, ensuring electrolysis efficiency and product quality;

[0019] 3. The anode and cathode assemblies are designed to be detachable, which facilitates regular inspection, cleaning and replacement when necessary, reducing maintenance difficulty and downtime. Attached Figure Description

Figure 1-2 As shown, the electrolytic cell includes an electrolytic cell body 1, an anode assembly 2, and a cathode assembly 3. The electrolytic cell body 1 has a space for containing electrolyte. An inlet pipe 5 is provided at the center of the bottom end of the electrolytic cell body 1.

[0029] With the above structure, before use, install the anode assembly 2 and the cathode assembly 3 to both ends of the electrolytic cell body 1, and use bolts to pass through the mounting plate 6 and connect it to the outer wall of the electrolytic cell body 1 to ensure good sealing. Fix the diaphragm 14 in the center of the electrolytic cell body 1 to separate the anode area and the cathode area.

[0030] It also includes a silica-based catalyst support 4; the silica-based catalyst support 4 is disposed on the anode assembly 2 and the cathode assembly 3 to improve the electrochemical reaction efficiency. The silica-based catalyst support 4 is preloaded on the anode assembly 2 and the cathode assembly 3 to ensure uniform distribution of the catalyst.

The installation cylinder 7 has a slot 9 that matches the electrolytic cell body 1. The cover plate 8 has an extension plate 10 that extends into the slot 9. After the bolt passes through the preset through hole on the cover plate 8, it is threadedly connected to the threaded hole on the installation cylinder 7.

[0033] With the above structure, the electrolytic cell body 1 is placed into the mounting cylinder 7 inside the temperature control housing, and then the open port of the mounting cylinder 7 is closed with the cover plate 8 to ensure that the extension plate 10 is correctly inserted into the slot 9. The cover plate 8 is then fixed to the mounting cylinder 7 with bolts, thus completing the rapid installation operation of the temperature control housing. The slot 9 facilitates the placement of the electrolytic cell body 1.

The heating plates 11 are arranged on the inner wall of the mounting cylinder 7, and a pair are arranged in a mirror image.

A temperature controller 13 is provided on the outer wall of the mounting cylinder 7 to cooperate with the heating plates 11 and the cooling pipe 12. The temperature controller 13 is electrically connected to the temperature sensor inside the mounting cylinder 7. The temperature control mechanism of the heating plate 11 and the cooling pipe 12 realizes precise control of the temperature of the electrolysis process.

[0035] In specific implementation of this utility model, before use, the silica-based catalyst carrier 4 is preloaded onto the anode assembly 2 and the cathode assembly 3 to ensure uniform catalyst distribution. The anode assembly 2 and the cathode assembly 3 are installed onto the mounting plate 6, and the mounting plate 6 is installed at both ends of the electrolytic cell body 1. Bolts are used to pass through the mounting plate 6 and connect it to the outer wall of the electrolytic cell body 1 to ensure good sealing.
