Description

Technical Field

[0001] This utility model relates to the field of ion membrane electrolysis technology, and in particular to an ion membrane electrolyzer for potassium hydroxide production. Background Technology

[0002] Potassium hydroxide, an inorganic compound with the chemical formula KOH, is a common inorganic alkali with strong alkalinity. A 0.1 mol / L solution has a pH of 13.5. It is soluble in water and ethanol, slightly soluble in ether, and readily absorbs moisture from the air, deliquescing. It absorbs carbon dioxide to form potassium carbonate. It is mainly used as a raw material for the production of potassium salts and can also be used in electroplating and dyeing. An electrolytic cell consists of a tank, an anode, and a cathode. Most electrolytic cells are separated from the cathode chamber by a diaphragm. Electrolytic cell equipment does not have protective covers, making it easy for external contaminants and impurities to contaminate the cell during use, leading to electrolysis failure and reduced efficiency.

[0003] The existing publication number CN221028704U discloses an ion-exchange membrane electrolyzer, which adds a detachable protective plate structure. The presence of slots and posts makes the cover plate more securely fixed at the top of the electrolyzer. Bolts connect the electrolyzer cover plate and facilitate disassembly. A glass window allows operators to observe the reaction process inside the electrolyzer. An electrode plate passage allows the electrode plate to pass through. The structure consisting of a feed pipe and a feed hopper can add reaction materials into the electrolyzer while providing protection. The protective plate structure provides an additional safety barrier, reducing the occurrence of accidents. It can effectively isolate the electrolyzer from the surrounding environment, reducing the risk of liquid leakage or splashing. In case of abnormalities, such as electrolyte leakage or reaction runaway, the protective plate can effectively prevent liquid diffusion, providing time for accident handling and emergency response.

[0004] However, the above-mentioned ion membrane electrolyzers are not easy to control in terms of temperature, which can easily lead to slow reactions within the electrolyzer and reduce processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an ion-exchange membrane electrolyzer for potassium hydroxide production, which solves the problem that the temperature of the ion-exchange membrane electrolyzer is difficult to control during use, which easily leads to slow reactions in the electrolyzer and reduced processing efficiency.

[0006] To achieve the above objectives, this utility model provides an ion-exchange membrane electrolyzer for potassium hydroxide production, comprising a tank body, a temperature control assembly, a sealing assembly, a diaphragm assembly, and a discharge assembly. The temperature control assembly includes a heating wire, a temperature control plate, a heat-conducting plate, and a sealing ring.

The sealing assembly is connected to the tank body, the diaphragm assembly is connected to the sealing assembly, and the discharge assembly is connected to the tank body.

[0007] The tank has multiple heat-conducting grooves inside, an inner sealing groove above each heat-conducting groove, two slots on the inner wall of the tank, and two outer sealing grooves on the upper surface of the tank.

[0008] The sealing assembly includes a cover plate, sealing strips, and electrodes. The cover plate is detachably connected to the groove and is located at the top of the groove. There are two sealing strips, which are fixedly connected to the cover plate and located inside the outer sealing groove. There are two electrodes, which are fixedly connected to the cover plate and pass through the cover plate.

[0009] The diaphragm assembly includes a mounting plate, fixing bolts, insert plates, and a diaphragm plate. The mounting plate is detachably connected to the cover plate and is located inside the groove. There are multiple fixing bolts, which are threaded to the groove and pass through the mounting plate. There are two insert plates, which are fixedly connected to the mounting plate and are located inside the slot. The diaphragm plate is detachably connected to the insert plates and is located between the two diaphragm plates.

[0010] The discharge assembly includes discharge pipes and sealing sleeves. There are two discharge pipes, which are fixedly connected to the tank body and pass through the tank body respectively. There are two sealing sleeves, which are detachably connected to the discharge pipes and are located on the outside of the discharge pipes respectively.

[0011] This invention relates to an ion-exchange membrane electrolyzer for potassium hydroxide production. The tank body is used for electrolyzing the raw materials during potassium hydroxide production. A heating wire is used to heat the tank body, a temperature control plate controls the heating wire, a heat-conducting plate conducts the heat from the heating wire to the interior of the tank body, and a sealing ring seals the gap between the heat-conducting plate and the tank body. In use, the temperature control plate heats the heating wire, facilitating the heating of the electrolyte within the tank and raising the reaction temperature to a suitable level, thus accelerating the electrolysis reaction. This invention solves the problem of inconvenient temperature control in ion-exchange membrane electrolyzers, which can lead to slow reactions and reduced processing efficiency.

[0020] The first embodiment of this application is as follows:

The present invention provides an ion-exchange membrane electrolyzer for potassium hydroxide production, including a tank body 101, a temperature control assembly, a sealing assembly, a diaphragm assembly, and a discharge assembly. The temperature control assembly includes a heating wire 102, a temperature control plate 103, a heat-conducting plate 104, and a sealing ring 105. The sealing assembly includes a cover plate 110, a sealing strip 111, and an electrode 112. The diaphragm assembly includes a mounting plate 113, fixing bolts 114, an insert plate 115, and a membrane plate 116. The discharge assembly includes a discharge pipe 117 and a sealing sleeve 118. The aforementioned solution solves the problem that the temperature of the ion-exchange membrane electrolyzer is difficult to control during use, which can easily lead to slow reactions and reduced processing efficiency. It is understood that the aforementioned solution can be used in scenarios where the electrolyte in the electrolyzer is heated, and can also be used to solve the problems of sealing and installing the device.

[0022] In this specific embodiment, the heating wire 102 is detachably connected to the tank 101 and is located inside the tank 101. There are two temperature control plates 103, each fixedly connected to the heating wire 102 and located on the outer side of the tank 101. The heat-conducting plate 104 is fixedly connected to the tank 101 and is located inside the tank 101. The sealing ring 105 is fixedly connected to the heat-conducting plate 104 and is located between the heat-conducting plate 104 and the tank 101. The sealing assembly is connected to the tank 101. The diaphragm assembly is connected to the sealing assembly. The discharge assembly is connected to the tank 101. Next, the tank 101 is used for electrolyzing the raw materials during the production of potassium hydroxide. The heating wire 102 is used to heat the tank 101. The temperature control plate 103 is used to control the heating wire 102. The heat-conducting plate 104 is used to conduct the heat from the heating wire 102 to the interior of the tank 101. The sealing ring 105 is used to seal the gap between the heat-conducting plate 104 and the tank 101. In use, the heating wire 102 is heated by the temperature control plate 103, which facilitates the heating of the electrolyte in the tank 101, facilitates raising the reaction temperature of the electrolyte to a suitable temperature, and facilitates increasing the speed of the electrolysis reaction.

[0023] The groove 101 has multiple heat-conducting grooves 106 inside, an inner sealing groove 107 above each heat-conducting groove 106, two slots 108 on the inner wall of the groove 101, and two outer sealing grooves 109 on the upper surface of the groove 101. The heat-conducting grooves 106 provide protection for the heating wire 102. The inner sealing groove 107 cooperates with the sealing ring 105 to provide a seal between the heat-conducting plate 104 and the groove 101. The slots 108 provide guidance and limiting for the insert. The outer sealing grooves 109 cooperate with the sealing strip 111 to provide a seal between the cover plate 110 and the groove 101.

[0024] Secondly, the cover plate 110 is detachably connected to the tank body 101 and is located on top of the tank body 101. There are two sealing strips 111, which are fixedly connected to the cover plate 110 and located inside the outer sealing groove 109. There are two electrodes 112, which are fixedly connected to the cover plate 110 and pass through the cover plate 110. The cover plate 110 is used to seal the top of the tank body 101 to prevent dust from entering the interior of the tank body 101. The sealing strips 111 cooperate with the outer sealing groove 109 to seal the gap between the cover plate 110 and the tank body 101. The electrodes 112 are connected to the outside. In use, the electrodes 112 are powered by an external power generation device, so that the electrodes 112 and the electrolyte in the tank body 101 form a closed circuit. One electrode 112 is the anode and the other electrode 112 is the cathode, which facilitates the conduction of the electrolyte.

[0025] Furthermore, the mounting plate 113 is detachably connected to the cover plate 110 and is located inside the groove 101. Multiple fixing bolts 114 are threadedly connected to the groove 101 and pass through the mounting plate 113. Two insert plates 115 are fixedly connected to the mounting plate 113 and are located inside the slot 108. The membrane plate 116 is detachably connected to the insert plates 115 and is located between the two membrane plates 113. Between 16, the mounting plate 113 provides a mounting function for the diaphragm assembly. The fixing bolt 114 facilitates the fixing of the mounting plate 113 to the bottom of the cover plate 110. In use, the insert plate 115 is inserted into the groove 101 along the slot 108 to provide guidance and limiting function for the cover plate 110. During electrolysis, the ion membranes provided on both sides of the membrane plate 116 facilitate the migration of potassium ions generated by electrolysis to the cathode chamber under the action of charge to combine with hydroxide ions to generate potassium hydroxide product.

[0026] Finally, there are two discharge pipes 117, which are fixedly connected to the tank 101 and pass through the tank 101 respectively. There are also two sealing sleeves 118, which are detachably connected to the discharge pipes 117 and are located on the outside of the discharge pipes 117 respectively. When discharging, the sealing sleeves 118 are opened to facilitate the solution in the tank 101 to be drawn out from the discharge pipes 117, thus facilitating the discharge of the processed solution.

[0027] Using the ion-exchange membrane electrolyzer for potassium hydroxide production in this embodiment, the tank body 101 is used to electrolyze the raw materials during potassium hydroxide production. The heating wire 102 is used to heat the tank body 101, the temperature control plate 103 is used to control the heating wire 102, the heat-conducting plate 104 is used to conduct the heat from the heating wire 102 to the interior of the tank body 101, and the sealing ring 105 is used to seal the gap between the heat-conducting plate 104 and the tank body 101. In use, the heating wire 102 is heated by the temperature control plate 103, which facilitates the heating of the electrolyte in the tank body 101, making it easier to raise the reaction temperature of the electrolyte to a suitable temperature and increase the speed of the electrolysis reaction. This solves the problem that ion-exchange membrane electrolyzers are not easy to control the temperature of the electrolyzer during use, which can easily lead to slow reactions in the electrolyzer and reduced processing efficiency.
