Description

Technical Field

[0001] This utility model relates to the field of hypochlorous acid preparation technology, specifically a hypochlorous acid electrolysis module. Background Technology

[0002] Hypochlorous acid (HClO) is a weakly acidic chlorine-containing compound with strong oxidizing properties. It is easily decomposed and unstable. Hypochlorous acid is one of the active components formed when chlorine (Cl2) dissolves in water, and its chemical formula is HClO. With its small molecular weight and strong penetrating power, it can destroy the cell membranes of microorganisms or the protein structure of viruses, achieving rapid killing. Due to its highly efficient sterilization and disinfection properties, as well as its safe and low-irritant characteristics, it is widely used in environmental sanitation, water treatment, and medical disinfection. Hypochlorous acid is mainly prepared by electrolyzing low-concentration saline solutions.

[0003] Existing methods for electrolyzing low-concentration brine produce chlorine and hydrogen, but the resulting chlorine needs to be mixed with sodium hydroxide solution again to obtain hypochlorous acid solution. This process is cumbersome and poses safety hazards when handling chlorine. Therefore, it does not meet the current requirements. To address this, we propose a hypochlorous acid electrolysis module. Utility Model Content

[0004] The purpose of this invention is to provide a hypochlorous acid electrolysis module to solve the problems mentioned in the background art, which involve generating chlorine and hydrogen gas during the electrolysis of low-concentration brine, requiring the obtained chlorine gas to be mixed with sodium hydroxide solution again to obtain hypochlorous acid solution, which is cumbersome and poses safety hazards when handling chlorine gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hypochlorous acid electrolysis module, including a mounting bracket, two electrolysis mounting units mounted on the front end face of the mounting bracket, an electrolysis generating unit mounted inside the electrolysis mounting unit, the electrolysis generating unit including a sealing cover, an electrolysis anode and an electrolysis cathode respectively mounted on the lower end face of the sealing cover, a honeycomb isolation seat mounted between the electrolysis anode and the electrolysis cathode, an ion exchange membrane mounted in the middle of the honeycomb isolation seat, and liquid level contact plates mounted on both sides of the upper end face of the honeycomb isolation seat on both sides of the ion exchange membrane.

[0006] Preferably, the electrolysis installation unit includes an electrolysis box, an electrolysis chamber is provided on the inner side of the electrolysis box, two brine input pipes are fixedly installed at the bottom of the front end face of the electrolysis box, an acid water output end and an alkaline water output end are respectively installed on the upper part of the front end face of the electrolysis box, and a maintenance sealing plate is fixedly installed on the rear end face of the electrolysis box.

[0007] Preferably, the mounting bracket and the two sealing caps are fixedly connected through an electrolysis chamber, and the upper end face of the sealing cap is provided with a gas inlet, which is connected in communication with the electrolysis chamber.

[0008] Preferably, the bottom ends of the electrolytic anode and the electrolytic cathode both penetrate the liquid level contact plate and are inserted into the interior of the bottom of the electrolysis tank. The brine input pipe, the acid water output end, and the alkali water output end are all connected in communication with the electrolysis chamber. The sealing cover is fixedly connected to the upper ends of the electrolytic anode and the electrolytic cathode. The electrolytic anode and the electrolytic cathode are electrically connected.

[0009] Preferably, the electrolysis tank is fixedly connected to the ion exchange membrane and the liquid level contact plate through a honeycomb isolation seat, and multiple flow guide holes are provided on both sides of the honeycomb isolation seat.

[0010] Preferably, the surface of the liquid level contact plate is provided with multiple vent holes, and the inner wall of the electrolysis tank is provided with a liquid level gauge.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model injects a low-concentration brine solution into the inner side of the electrolysis chamber through four brine input pipes. When the electrolysis anode and electrolysis cathode are connected to the power supply, the brine solution is electrolyzed, and chlorine and hydrogen are generated on both sides of the honeycomb isolation seat, respectively. As the chlorine and hydrogen rise in the electrolysis chamber, the chlorine can combine with sodium hydroxide to generate sodium hypochlorite. The sodium hypochlorite solution is output through the acid water output terminal, and the sodium hydroxide solution is output through the alkali water output terminal. The liquid level of the brine solution is monitored by a level gauge to maintain efficient electrolysis of the brine solution.

[0013] 2. This utility model guides hydrogen gas through a liquid level contact plate and outputs it through a gas outlet on the surface of the sealing cover. Multiple flow guide holes are provided on both sides of the honeycomb isolation seat. Thus, the honeycomb isolation seat and ion exchange membrane can guide the flow of the solution and block ions during the electrolysis of the brine solution. Hypochlorous acid solution is directly generated while electrolyzing the brine, avoiding the mixing of chlorine gas and sodium hydroxide solution, effectively improving the efficiency of hypochlorous acid preparation and operational safety.

[0019] 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.

[0020] Please see Figures 1 to 3 This utility model provides an embodiment of a hypochlorous acid electrolysis module, including a mounting bracket 1. Two electrolysis mounting units 2 are mounted on the front end of the mounting bracket 1. Each electrolysis mounting unit 2 includes an electrolysis tank 201. A level gauge is provided on the inner wall of the electrolysis tank 201. An electrolysis chamber 206 is provided on the inner side of the electrolysis tank 201. Two brine input pipes 202 are fixedly installed at the bottom of the front end of the electrolysis tank 201. An acid water output terminal 203 and an alkaline water output terminal 204 are respectively installed on the upper part of the front end of the electrolysis tank 201. The brine input pipes 202, acid water output terminal 203, and alkaline water output terminal 204 are all connected to the electrolysis chamber 206. A maintenance sealing plate 205 is fixedly installed on the rear end of the electrolysis tank 201. The level of the brine solution is monitored by the level gauge to maintain efficient electrolysis of the brine solution. Sodium hypochlorite solution is output through the acid water output terminal 203, and sodium hydroxide solution is output through the alkaline water output terminal 204.

[0021] Please see Figure 1 , Figure 3 and Figure 4 An electrolysis generating unit 3 is installed inside the electrolysis mounting unit 2. The electrolysis generating unit 3 includes a sealing cover 301. The mounting bracket 1 and the two sealing covers 301 are fixedly connected through the electrolysis box 201. The upper end face of the sealing cover 301 is provided with a gas inlet, which is connected to the electrolysis chamber 206. An electrolysis anode 302 and an electrolysis cathode 303 are respectively installed on the lower end face of the sealing cover 301. The sealing cover 301 is fixedly connected to the upper end of the electrolysis anode 302 and the electrolysis cathode 303. The electrolysis anode 302 and the electrolysis cathode 303 are electrically connected, so that when the electrolysis anode 302 and the electrolysis cathode 303 are connected to the power source, they electrolyze the brine solution and generate chlorine and hydrogen on both sides of the honeycomb isolation seat 304. Then, as the chlorine and hydrogen rise in the electrolysis chamber 206, the chlorine can combine with sodium hydroxide to generate sodium hypochlorite.

[0022] A honeycomb isolation seat 304 is installed between the electrolytic anode 302 and the electrolytic cathode 303. Multiple flow guide holes are provided on both sides of the honeycomb isolation seat 304. An ion exchange membrane 305 is installed in the middle of the honeycomb isolation seat 304. Liquid level contact plates 306 are installed on both sides of the ion exchange membrane 305 on the upper end surface of the honeycomb isolation seat 304. Multiple vent holes are provided on the surface of the liquid level contact plates 306. The bottom ends of the electrolytic anode 302 and the electrolytic cathode 303 pass through the liquid level contact plates 306 and are inserted into the bottom of the electrolysis tank 201. The electrolysis tank 201 is fixedly connected to the ion exchange membrane 305 and the liquid level contact plates 306 through the honeycomb isolation seat 304. The honeycomb isolation seat 304 and the ion exchange membrane 305 enable directional flow of the solution and ion blocking during the electrolysis of the brine solution.

[0023] In summary, during the preparation of hypochlorous acid, a low-concentration brine solution is injected into the inner side of the electrolysis chamber 206 through four brine input pipes 202. When the power is turned on, the bottom ends of the electrolytic anode 302 and electrolytic cathode 303 penetrate the liquid level contact plate 306 and are inserted into the inner side of the bottom of the electrolysis tank 201. This allows the electrolytic anode 302 and electrolytic cathode 303 to electrolyze the brine solution when powered on, generating chlorine and hydrogen gas respectively on both sides of the honeycomb isolation seat 304. As the chlorine and hydrogen gas rise within the electrolysis chamber 206, the chlorine gas combines with sodium hydroxide to generate sodium hypochlorite. The sodium hypochlorite solution is then output through the acid water output terminal 203, while the sodium hydroxide solution is output through the alkaline water output terminal 204.

[0024] A level gauge is installed on the inner wall of the electrolysis tank 201 to monitor the level of the brine solution and maintain efficient electrolysis. Multiple vent holes are provided on the surface of the level contact plate 306 to guide hydrogen gas through the level contact plate 306 and output it through the gas outlet on the surface of the sealing cover 301. Multiple flow guide holes are provided on both sides of the honeycomb isolation seat 304, so that the honeycomb isolation seat 304 and the ion exchange membrane 305 can perform directional flow guidance of the solution and ion blocking during the electrolysis of the brine solution.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
