Description

Technical Field

[0001] This utility model belongs to the field of ion membrane electrolysis technology, and particularly relates to an ion membrane anode frame for electrolysis. Background Technology

[0002] Ion-exchange membrane electrolysis is an electrolysis technology that separates cations and anions during the electrolysis process using ion-exchange membranes, preventing them from mixing directly in the electrolytic cell. Ion-exchange membrane electrolysis is widely used in the chlor-alkali industry, such as in the production of chlorine and hydrogen.

[0003] In ion-exchange membrane electrolysis, an ion-exchange membrane is a special thin film that selectively permeates to specific ions. Typically, it allows permeation of cations (such as sodium ions) while blocking anions (such as chloride ions). The application of this membrane can make the electrolysis process more efficient, reduce side reactions, and increase the yields of chlorine and hydrogen.

[0004] In the chlor-alkali electrolysis process, the electrolyte is usually a sodium chloride solution. When the current passes through the electrolytic cell, chlorine gas is generated at the anode and hydrogen gas is generated at the cathode. The ion exchange membrane prevents direct contact between chloride ions and hydroxide ions, thus effectively preventing the formation of sodium hydroxide.

[0005] In electrolysis applications, ion exchange membranes often require the separation of positive and negative electrode solutions, while ensuring that these solutions do not come into contact with each other during use. Traditional methods involve bonding and sealing the ion exchange membrane to the anode frame using silicone adhesive, hot melt adhesive, or PE adhesive. However, during use, changes in the positive and negative electrode solutions due to electrolysis can cause the adhesive to detach from the anode frame or the ion exchange membrane, leading to the exchange of positive and negative electrode solutions. This results in electrolysis results or conclusions that deviate significantly from the actual data and conclusions.

[0006] To address the above problems, this application proposes an ion-exchange membrane anode frame for electrolysis. Utility Model Content

[0007] The purpose of this invention is to provide an ion-exchange membrane anode frame for electrolysis to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an ion membrane anode frame for electrolysis, comprising an anode frame body, ion membranes symmetrically arranged on both sides of the anode frame body, an acid and alkali resistant sealing gasket between the ion membranes and the anode frame body, the acid and alkali resistant sealing gasket being frame-shaped and adapted to the anode frame body, and a fixing frame provided on the side of the ion membrane facing away from the anode frame body.

[0009] Preferably, the side wall of the anode frame is provided with a threaded hole, and the acid and alkali resistant sealing gasket, ion membrane and fixing frame are connected to the anode frame with screws, and the screws are connected to the threaded hole.

[0010] Preferably, the anode frame includes a base plate, a left side plate, a right side plate, and a front panel. The base plate, left side plate, right side plate, and front panel cooperate with each other to form a frame. The bottom surface of the base plate is provided with a support leg, and the right side plate is provided with a small flexible joint.

[0011] Preferably, the base plate, left side plate, right side plate, and front panel are made of PVC, PP, or PE material.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Example

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: an ion membrane anode frame for electrolysis, including an anode frame body 5, ion membranes 3 symmetrically arranged on both sides of the anode frame body 5, an acid and alkali resistant sealing gasket 4 between the ion membrane 3 and the anode frame body 5, the acid and alkali resistant sealing gasket 4 being frame-shaped and adapted to the anode frame body 5, and a fixing frame 2 being provided on the side of the ion membrane 3 facing away from the anode frame body 5.

[0024] The side wall of the anode frame 5 is provided with a threaded hole. The acid and alkali resistant sealing gasket 4, the ion membrane 3 and the fixing frame 2 are connected to the anode frame 5 by a screw 1, which is engaged with the threaded hole.

[0025] In this embodiment, threaded holes are first opened at appropriate positions on the side wall of the anode frame 5, and then holes are opened at corresponding positions for the acid and alkali resistant sealing gasket 4, ion membrane 3 and fixing frame 2. Finally, they are installed in sequence and screws 1 are tightened to press the fixing frame 2 against the anode frame 5. The ion membrane 3 and acid and alkali resistant sealing gasket 4 between the fixing frame 2 and the anode frame form a sealing effect as the pressure increases.

[0026] The principle of this device during operation is as follows: Figure 4 As shown, the negative electrode solution is a dotted shadow, and the positive electrode solution is a straight shadow at a 45° angle. During the electrolysis process, the positive and negative electrode solutions are separated only by an ion membrane 3. The anode frame 5 is fixed to the fixed frame 2 on both sides by screws 1, which clamps and seals the acid and alkali resistant gasket 4 and the ion membrane 3, so that the positive and negative electrode solutions will not come into contact or exchange with each other during the electrolysis process.

[0027] Furthermore, the anode frame 5 includes a base plate 56, a left side plate 52, a right side plate 55, and a front panel 53. The base plate 56, the left side plate 52, the right side plate 55, and the front panel 53 cooperate with each other to form a frame. The bottom surface of the base plate 56 is provided with a support leg 51, and the right side plate 55 is provided with a small connecting joint 54.

[0028] The base plate 56, left side plate 52, right side plate 55 and front panel 53 are made of PVC, PP or PE material; when the base plate 56, left side plate 52, right side plate 55 and front panel 53 are made of PVC material, they are bonded together with PVC glue; when the base plate 56, left side plate 52, right side plate 55 and front panel 53 are made of PP or PE material, they are welded together.

[0029] In this embodiment, when the anode frame 5 is made of different materials, the components forming the anode frame 5 can be connected in different ways.

[0030] This solution eliminates the need for additional adhesives to bond the anode frame 5 to the ion exchange membrane 3, thus avoiding the problem of adhesive detaching from the anode frame 5 or the ion exchange membrane 3. This ensures that the sealing effect will not change due to variations in the positive and negative electrode solutions during electrolysis, guaranteeing the accuracy of electrolysis results, ensuring the safety of the electrolysis process, preventing side reactions and cross-contamination of products, improving product purity and collection efficiency, enhancing current efficiency and energy utilization, extending electrode life and reducing corrosion, and controlling the influence of impurities.

Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
