Description

The present invention relates to the use of an electrolyzed water generating apparatus in the medical field and the sterilization and cleaning of the electrolyzed water. In particular, the present invention relates to sterilizing effect and cleaning ability that do not cause salt damage, and various articles that can be easily treated after washing. And a cleaning agent for equipment.

Most electrolyzed water generators in the medical field use a method utilizing the sterilizing effect of strongly acidic electrolyzed water. Moreover, the conventional electrolyzed water generating apparatus cannot obtain a sufficient effect because sodium is mixed in the electrolyzed water and salt damage occurs after use. Furthermore, it is not possible to make full use of both extreme acidic electrolyzed water and strong alkaline electrolyzed water generated from the electrolyzed water generator, and in particular, only using strongly acidic electrolyzed water I don't think the generator is fully utilized.
An object of this invention is to utilize in the medical field | area using the capability of each of the strong acidic electrolyzed water and strong alkaline electrolyzed water without salt damage produced | generated from an electrolyzed water generating apparatus.

Problems to be solved by the invention

The use of electrolyzed water generators in the medical field is intended to use strongly acidic electrolyzed water, and the use of strong alkaline electrolyzed water has not been sufficient. Mainly, the use of strong acidic electrolyzed water is for the sterilization of atopic dermatitis, the sterilization of hospital and bedridden patients, and the sterilization of kitchens and foodstuffs. However, the sodium mixed in the electrolyzed water is irritating to the skin, and in the hospital sterilization, the metal in the building is oxidized, and the sterilization of the food is also worried about the mixing of sodium. I had a problem. The problem of strongly acidic electrolyzed water can be solved by using electrolyzed water that does not contain sodium. In order to obtain electrolyzed water free from sodium contamination, the object can be achieved by using an electrolyzed water generating apparatus incorporating a cylindrical electrode using a diaphragm having ion selective permeation performance developed by Eletech Engineering Co., Ltd.
As described above, strong acidic electrolyzed water is often used, and in the medical field, strong alkaline electrolyzed water is rarely used. Considering a method of using strongly alkaline electrolyzed water for medical treatment leads to the development of medical relations.
Therefore, it was devised to use strong alkaline electrolyzed water as a cleaning agent for all the places where it can be used in hospitals, such as hospital rooms, kitchens, toilets, bathrooms, waiting rooms, entrances, and appliances. Even in the use of strong alkaline electrolyzed water, it is a condition to obtain electrolyzed water that does not contain sodium during washing. To satisfy this condition, strong alkaline electrolyzed water that is simultaneously produced when producing strongly acidic electrolyzed water is used. Can be solved by using.

Conventional general detergents are widely used as detergents composed of fluorinated organic compounds having excellent properties such as solubility, drying property at low temperature, and insolubility of substrates. A cleaning agent composed of a fluorinated organic compound is extremely excellent as a cleaning agent for dissolving and removing organic substances such as fats and oils, but its use has been prohibited due to problems such as environmental pollution, particularly ozone layer destruction.
As a substitute for these fluorinated organic compounds, a solvent that protects the ecosystem and does not destroy the environment has been developed. The Japanese government has established “Power Development Co., Ltd.” in cooperation with a power company to stabilize domestic power, and its subsidiary “Dentsu Environmental Greening Center Co., Ltd.” For the purpose of wastewater treatment, it was developed so as not to cause pollution of surrounding rivers and seawater, ecosystem changes and environmental destruction, using strong alkaline electrolyzed water with an appropriate amount of sodium metasilicate or sodium carbonate added as a buffer material. It is an earth-friendly cleaning agent. In order to use this environmentally friendly cleaning agent in the medical field, the manufacturing method of this cleaning agent has been improved, and an electrolyzed water generator that has been devised to prevent sodium from being mixed into the electrolyzed water has been used to provide strong alkalinity. A detergent for electrolyzed water was produced.
General hospitals and industrial cleaning agents are mainly fluorinated organic compounds used in machine parts, electronic parts, and clothing, and most of the general cleaning agents are synthetic detergents that use petroleum as the raw material, and the main ingredients are chemical substances. It is a dishwashing detergent using sodium hydroxide (caustic soda) and potassium hydroxide as raw materials, soap (fatty acid sodium) reacted by adding caustic soda to animal and vegetable oils and heating, and a bleaching agent based on chlorine.
These detergents cause eutrophication of rivers and seawater, the generation of sludge, blue sea urchins, and red tides in each region, and the harmful effects of fluorine and surfactants, which are the main components, and the slowness of decomposition. It is the cause. Also in the medical field, it is a problem to use the strong alkaline electrolyzed water cleaning ability and the strong acidic electrolyzed water sterilizing ability that do not cause environmental destruction.

Means for solving the problem

In order to solve the problem, it is necessary to produce a cleaning agent that does not use a surfactant or a fluorinated organic compound. For the production of the cleaning agent, an electrolyzed water generator is used to produce strongly alkaline electrolyzed water, and an appropriate amount of sodium metasilicate or sodium carbonate is added to the electrolyzed water as a buffer material. For the production of the sterilizing solution, the generated strongly acidic electrolyzed water of pH 3 or lower is used to exert the sterilizing action. However, the conventional electrolyzed water generating apparatus must use a spacer to keep the distance between the diaphragm and the electrode of the electrolytic cell uniform. However, the spacer is a pressure loss of supply water due to a flow path failure or a local diaphragm electrode. There is also the problem of causing pressure on the Furthermore, even if various attempts are made to contact the spacer with various spacers, it is necessary to pay close attention so that the intermediate tank pressure becomes the optimum anode for the pressure between both tanks. There is also a problem in that the generated water is restricted in handling or a complicated pressure balance adjusting mechanism must be provided.
In addition, when the intermediate tank pressure is set to a positive pressure with respect to both tanks by the above-described method, the water flow rate increases due to deterioration of the diaphragm which is a consumable product, and the undecomposed high-concentration electrolyte solution flows into the electrolyte. It is impossible to obtain an extra loss of water and predetermined physical properties of the generated water.
This problem can be solved by providing an electrode device and an electrolytic cell that can be used in a device that continuously generates high-purity electrolyzed water by electrodialysis of a solution containing water or an electrolyte. .

The invention's effect

A conventional electrolyzed water generator performs electrolysis by introducing a diluted NaCl solution (about 1000 to 2000 ppm) into an anolyte / catholyte partitioned with a nonwoven fabric or the like. At this time, in order to produce water having an effective chlorine concentration of 50 ppm, it is unavoidable to mix undecomposed excess NaCl of about 900 to 1800 ppm.
Unlike the conventional electrolyzed water generating device, the electrolyzed water generating device used in the present invention excites Cl −, which has been dialyzed in the anode chamber according to Faraday's law, to effective chlorine on the electrode surface. At this time, by using an ion exchange membrane for the diaphragm, it is possible to strictly limit Na + contamination.
Whereas a conventional electrolysis generator produces effective chlorine from Cl- in a uniformly concentrated NaCl solution, the electrolyzed water generator used in the present invention dialyzes by installing an electrode in the vicinity of the ion exchange membrane described above. Since it is effectively chlorinated on the electrode surface before diffusing into the formed Cl-bulk solution, very efficient electrolysis is possible.
For example, the strongly acidic electrolyzed water or strong alkaline electrolyzed water has a Cl-concentration of about 180 ppm, which is about 1/10 to 1/8 of that of a conventional electrolyzed water generator, and has an effective chlorine of 50 ppm. It is possible to generate electrolyzed water. About Na +, except for what is contained in raw | natural water, it is hardly contained.
Thus, since the strongly acidic electrolyzed water and strong alkaline electrolyzed water produced | generated with the electrolyzed water generating apparatus used for this invention hardly contain NaCl, the long-term washing | cleaning effect can be maintained. A detergent made by adding an appropriate amount of sodium metasilicate or sodium carbonate as a buffer material to strong alkaline electrolyzed water not containing NaCl can achieve its purpose without destroying the ecosystem and the environment. Even in strongly acidic electrolyzed water having a bactericidal action, the electrolyzed water generating apparatus used in the present invention has a bactericidal effect with strong alkaline electrolyzed water that can maintain a long-term cleaning ability by using a product of Elex Engineering Co., Ltd. Strongly acidic electrolyzed water can be obtained.

A sterilizing solution having a sterilizing effect by using a strong alkaline electrolyzed water or a detergent obtained by adding an appropriate amount of sodium metasilicate or sodium carbonate as a buffer material to the strongly alkaline electrolyzed water generated from the electrolyzed water generating device used in the present invention In the process of processing from raw materials to commercialization while maintaining the natural and natural state of the product as much as possible, the product form has few quality deterioration factors such as additives, heat, water, pressure, air, oxidation, etc. Must be taken into account. In addition, factors such as daily usage, ease of handling, cost, and related laws and regulations must be considered.
Commercialization of strongly alkaline electrolyzed water added with an appropriate amount of sodium metasilicate or sodium carbonate or strongly acidic electrolyzed water having a bactericidal effect is known per se. It mix | blends by the method and it can be set as the cleaning agent which has an effect effect, and the sterilization liquid which has a bactericidal effect. The additive to be used is not particularly limited, and can be appropriately selected by those skilled in the art depending on the specific use of the intended effect. Further, the form is not particularly limited, and various shapes can be used according to specific applications.

“Manyotei” in Sarugakyo Onsen, Gunma Prefecture is a ryokan that can accommodate about 40 people and uses a fully automatic dishwasher in the kitchen. Strong alkaline electrolyzed water containing sodium metasilicate diluted 3 times was used for the fully automatic dishwasher. As a result, the oil and protein in the tableware were very well removed, and the inside of the glass window of the washing machine became visible. It is easy to use because it doesn't batter, and it is also used for bath cleaning.

A family of four ate Chinese food for dinner. When washing dishes after a meal, a strong alkaline electrolyzed water solution with sodium metasilicate added is diluted 100-fold with tap water to make a solution. It was soaked in a plastic bucket containing alkaline electrolyzed water. After about 30 seconds, the dishes were washed with hot water. The oil and dirt were removed and the tableware became shiny.

The effect of strongly acidic electrolyzed water was tested at Yamada Hospital in Tamano City, Okayama Prefecture. This assistant director Masato Yamada suffers from systemic atopic dermatitis. The body is always itchy and there is no time to rest, and the body is scratched. Until now, we used strong acid electrolyzed water from conventional electrolyzed water generators, but strong acid electrolyzed water mixed with sodium is irritating to damaged skin and can continue to be used. There wasn't. When strong acidic electrolyzed water generated from the electrolyzer used in the present invention was sprayed over the bath, no irritation was felt on the skin and no itching of the skin was felt.

Strong alkaline electrolyzed water to which sodium metasilicate has been added is more environmentally friendly than a surfactant and has an excellent cleaning effect. In particular, because it demonstrates its ability to decompose fats and oils and proteins, by washing the dishes, the treated water cleans the drain and further helps clean the grease strap.

Strong alkaline electrolyzed water added with sodium metasilicate produced by conventional electrolyzed water generators is used for power stations, Shinkansen car body washing, jet machine air washing, foreign car body oil spills, washing company detergents, oils and fats Used by the manufacturing company and already used.

Conventional electrolyzed water generators use strongly acidic electrolyzed water for the anti-inflammatory action of dermatitis. Iida Hospital in Nagano Prefecture is famous for using strongly acidic electrolyzed water to treat atopic dermatitis. Since the effect of strong acidic water can be expected sufficiently, strong acidic electrolyzed water is used in hospitals nationwide.

The strongly alkaline electrolyzed water produced by the electrolyzed water producing apparatus used in the present invention can be used as an innovative cleaning agent from which NaCl is removed as much as possible. Furthermore, taking advantage of the fact that NaCl is not mixed into the generated electrolyzed water, which is a feature of the electrolyzed water generating apparatus used in the present invention, not only a strong alkaline electrolyzed water cleaning agent but also a strong acidity having a sterilizing effect that is generated simultaneously. Electrolyzed water can also be effective with conventional methods of use.

Furthermore, in agriculture, the electrolyzed water generator used in the present invention solves the problems of conventional electrolyzed water generators such as inflow of undecomposed high-concentration electrolyte solution, loss due to deterioration of electrolyte diaphragm, generation of harmful gases, etc. As a result, salt damage is not caused, so that it is possible to exert a sufficient effect on pesticide-free cultivation.
Kagome Co., Ltd. has begun pesticide-free cultivation using the electrolyzed water generator used in the present invention.

In the medical field, sodium does not adhere to the skin, so it can be used to treat atopic dermatitis. Also, hospital facilities are not affected by sodium, preventing hospital infections, sterilizing bedridden patients, and cleaning medical facilities and equipment. Available.
