Description
Technical Field
The invention relates to a device and a method for preparing hypochlorous acid water, and belongs to the technical field of water electrolysis.
Background
Currently, new types of coronaviruses are spreading manly around the world. Various disinfection products are sold on the market at a time for sterilization and disinfection. Among them, hypochlorous acid water is a new favorite in the market because of its broad-spectrum and high-efficient capability of killing virus microorganisms and its safety in use. The national food and drug administration of America and the Japan Thick health labor province successively affirm that low-concentration slightly acidic hypochlorous acid water is used as a food additive, and the national standard GB/T36758-2018 'hygienic requirement of chlorine-containing disinfectants' emphasizes that the hypochlorous acid water can be used in various occasions such as medical health institutions, various public places, food processing, restaurant stores, families and the like; and can also be used for the disinfection of various objects, including the disinfection of endoscopes, surgical instruments, sores/wounds, skin mucosa, air, hands, object surfaces, fabrics, fruits and vegetables, tableware, secondary water supply equipment, and the like.
Hypochlorous acid water belongs to a chlorine-containing disinfectant, and the sterilization effective component of the hypochlorous acid water is hypochlorous acid (HC L O), the pH value of the hypochlorous acid water has great influence on the hypochlorous acid concentration in the water, when the pH value is within the range of 5.5-6.5, the hypochlorous acid concentration tends to be the maximum, the sterilization effect of the hypochlorous acid water is also greatly enhanced, the more alkaline the pH value is, the more hypochlorous acid in the hypochlorous acid water exists in the state of hypochlorite ion (OC L-), the sterilization capability is reduced (according to related tests, the hypochlorous acid ion sterilization capability is only about 80/1 of hypochlorous acid), and if the pH value of the hypochlorous acid water is more acidic, the generated chlorine gas in the water is increased, and the hypochlorous acid concentration is also reduced (the relation is shown in.
The known standard method is to electrolyze dilute hydrochloric acid water (generally diluted by pure water) with the concentration of 2-6% by a one-chamber diaphragm-free electrolytic cell under the direct current voltage of about 2V to generate chlorine gas and H + at an anode, dissolve the chlorine gas and the H + in water to make the water acidic, react the chlorine gas with the water to generate hydrochloric acid and hypochlorous acid (HC L O) to make the effective chlorine concentration in the water reach 10-30 mg/L, and generate hydrogen gas at a cathode.
Hydrochloric acid is expensive and is a very toxic hazardous substance, so that the hydrochloric acid cannot be popularized and used because the substance is not easily available. At present, common salt (sodium chloride) is used to replace hydrochloric acid.
Sodium chloride is used as an electrolytic solution to prepare hypochlorous acid water, and a typical method is to adopt two-chamber type or three-chamber type diaphragm electrolysis. Taking a two-chamber electrolytic cell as an example, raw water (salt water) is sent into an anode chamber (or sent into a cathode chamber simultaneously), the water outlet of the anode chamber is acidic electrolyzed water, the water outlet of the cathode chamber is alkaline electrolyzed water, the alkaline electrolyzed water produced by the cathode chamber is mixed with the acidic electrolyzed water produced by the anode chamber according to a certain proportion, the pH value of the acidic electrolyzed water produced by the anode chamber is increased, and finally subacidic hypochlorous water with the pH value of 5.5-6.5 is obtained.
Another method for preparing hypochlorous acid water is to electrolyze sodium chloride aqueous solution without diaphragm to obtain alkaline sodium hypochlorite solution, then add acid solution (typically dilute hydrochloric acid or weak acid such as acetic acid and carbonic acid) to sodium hypochlorite solution in proportion, and gradually reduce the alkalinity of sodium hypochlorite solution until becoming neutral or slightly acidic hypochlorous acid water.
The key point of the existing device for preparing hypochlorous acid water by electrolyzing salt water is the online monitoring of pH value, and the online monitoring of oxidation-reduction potential or available chlorine is also arranged in some devices.

A dc power supply 6 powers the cathode electrode 2 and the anode electrode 5 to form a diaphragm-free electrolysis of the solution in the container 1. The side wall of the container 1 is provided with a liquid inlet 7, a liquid inlet valve 9, a liquid outlet 8 and a liquid outlet valve 10. The bottom of the container 1 when it is normally placed is provided with an opening 3 to the atmosphere, and the cathode electrode 2 is close to the opening and leaves a passage for the solution in the container 1 to pass through the opening. The opening is provided with a resistance part 4 which forms resistance pressure for the solution in the container 1 to flow outwards through the opening. In this embodiment, the resistance member 4 is a microporous metal plate (expanded metal plate) with pores having a diameter of 10-100 μm, and the expanded metal plate has a surface tension to a salt-containing solution such as water or saline water that can form a resistance pressure to the solution in the container, and the resistance pressure is generally constant according to the formation of the expanded metal plate and the pores thereof.
The process of preparing hypochlorous acid water specifically by the hypochlorous acid water preparing device of this embodiment is:
1) the volume of the container 1 is set to a first volume V1 and the volume containing the saline solution is set to a second volume V2, such that the first volume V1 is greater than the second volume V2. In this embodiment, the second volume V2 may be h1 xS or (h1+ h2) xS, where h is the internal height h of the container 1, h1 is the distance from the anode 5 to the top surface of the container 1, h2 is the distance from the anode 5 to the bottom surface of the container 1, h1+ h2 < h, and the cross-sectional area S of the container 1.
2) A resistance element 4 having a certain constant resistance pressure is selected and arranged at the opening 7 of the container 1. The resistance pressure piezoresistive of the solution of the resistance element 4 can be obtained by experiment.
3) The container 1 is placed in a normal state (namely, the anode electrode 5 is positioned above the cathode electrode 2), brine with a second volume V2 is filled into the container 1, and the gravity pressure Pigravity-resistance pressure Piar of the brine filled into the container 1 before electrolysis is less than or equal to atmospheric pressure.
4) The electrolysis time T is set according to the second volume, typically obtained by experiments on different volumes of saline solution. Turning on a direct current power supply 6 to supply power to the cathode electrode 2 and the anode electrode 5, and electrolyzing the saline water; the electrolysis takes place with the following electrochemical reactions:
2NaCL+2H2O+e→2NaOH+H2+Cl2+O2 (1)
2H2O+e→2H2+O2 (2)
H2O+Cl2→HClO+HCl (3)
2NaOH+Cl2＝2NaClO+H2 (4)；

When the electrolysis starts, the P gas + the P weight-P resistance is less than or equal to the atmospheric pressure, and at the moment, the saline can not be discharged through the micropores under the action of the resistance pressure formed by the surface tension of the liquid at the micropores of the metal mesh plate and the atmospheric pressure.
5) In the electrolysis, when the pressure P gas + P heavy-P resistance in the container 1 is larger than the atmospheric pressure, the solution generated after the electrolysis of the brine in the container 1 is discharged outwards through the micropores of the resistance piece 4 (the metal mesh plate) at the opening 3. The cathode side product NaOH contained therein is discharged from the micropores, and at this time, it can be observed that the solution is discharged from the opening 7, so as to reduce the alkalinity of the solution in the container and make the pH value as low as possible.
6) And when the electrolysis time T is reached, the direct current power supply 6 is closed, the drain valve 10 is opened, and the brine is discharged to generate solution after electrolysis. The anode side product hypochlorous acid HClO and sodium hypochlorite NaClO are contained to obtain the required solution containing hypochlorous acid HClO.
In this embodiment, the second volume V2 is the total amount of the prepared liquid that can be discharged, and when the discharged liquid exceeds the second volume V2, the distance between the liquid level of the container 1 and the top surface of the container 1 will be greater than h, i.e. the anode 5 is exposed from the liquid level, at this time, the electrolytic current drops to zero, and the electrolysis is automatically stopped, thereby achieving safety protection.
