Description

Electrolytic hypochlorous acid sterilization water production apparatus {Manufacturing Apparatus of Electrolysis Hypochlorous Acid Sterilization Water}

The present invention relates to an electrolytic hypochlorous acid sterilizing water production apparatus.

Sterilization is the application of physical and chemical stimuli to microorganisms that kill them in a short time. Depending on the degree, the distinction is made between sterilization, in which the subject is completely aseptic, and disinfection, reaching an almost aseptic state. Sterilization is caused by mechanical breakdown of cells, strong denaturation of proteins, and inactivation of enzymes. There are physical and chemical methods. Physical sterilization provides a physical environment in which germs are sterilized by using drying, sunlight, ultraviolet rays, radiation, and the like, on the object. Chemical sterilization provides a chemical environment in which germs can be sterilized using sterilizing agents, sterilizing gases, and the like.

Sterilization mainly removes harmful bacteria that harm the human body, and in the case of food, it is removed by washing. If harmful bacteria remain, it can cause food poisoning, waterborne diseases, and the like. That is, food poisoning or waterborne diseases develop when bacteria causing waterborne diseases and bacteria causing food poisoning remain in tableware, food processing equipment, cooking utensils, food factory manufacturing equipment, and group feeding facilities. Therefore, in order to prevent food poisoning and waterborne diseases, it is necessary to kill germs in tableware, food processing equipment, cooking utensils, food factory manufacturing equipment, and group feeding facilities. The sterilization as described above is mainly used physical and chemical methods, but this requires a device and equipment according to the sterilization and takes a long time.

Accordingly, in recent years, by disinfecting at the same time by replacing the washing water that can be easily washed with various cooking equipment with sterilization water, the sterilization efficiency is increased. In the case of food, sterilization and disinfection are required to ensure safety. Currently, disinfectant disinfectants are designated for management under the Food Hygiene Act.

The chlorine (Cl ₂ ) disinfection method is used for the sterilization of tap water that is routinely supplied and used for washing. Chlorine sterilizes or inactivates microorganisms by changing the permeability of microbial cell membranes. Chlorine disinfection has been widely used as a water disinfectant because of its excellent persistence and economic feasibility.

However, it has been known that trihalomethane (THM), a carcinogen, is produced by the reaction of chlorine with organic compounds of raw water sterilized with chlorine. In particular, the amount of trihalomethane increases as the amount of chlorine supplied increases. In addition, chlorine has a characteristic smell and remains after disinfection. Therefore, the situation is reducing the amount of chlorine used for disinfection in order to minimize the production of carcinogens and to suppress the smell. Alternative disinfection methods include ozone (O ₃ ), ultraviolet (UV light), chlorine dioxide (ClO ₂ ), and sodium hypochlorite (NaOCl).

Accordingly, the disinfection effect is reduced due to the reduction of the amount of chlorine used, and the amount of chlorine remaining is reduced, so that the bacteria remaining in the pipe during transportation of the tap water are not sterilized and contaminated. Therefore, in order to enhance the sterilization effect, sterilizing water containing a sterilizing material is used. Sterilizing water sterilizes germs in contaminated substances or cooking utensils and food ingredients used in food to sterilize bacteria causing food poisoning or waterborne diseases, thereby improving stability.

Conventional sterilizing water mainly uses a disinfection method using sodium hypochlorite. Sodium Hypochlorite is used as a disinfectant to kill food decay or pathogens. It is used in beverages, vegetables and fruits, containers, utensils and tableware. Sodium hypochlorite is well soluble in water, and the aqueous solution decomposes during storage to generate chlorine gas. The bactericidal power is influenced by the hydrogen ion concentration (pH) and the effective chlorine amount, and is in a non-relative state. The lower the hydrogen ion concentration (pH), the stronger the bactericidal power.

Sodium hypochlorite disinfection method is a method of injecting commercially available sodium hypochlorite (NaOCl), and directly generated by electrolysis in the field used. In order to increase the sterilizing power, a large amount of sodium hypochlorite should be used, thereby increasing the equipment for producing sterilizing water. Sterilized water produced by large production facilities can be reduced in production costs only when a large amount of sterilized water is produced in one operation. Therefore, there is a need for an apparatus for storing and moving sterile water produced in large quantities.

In order to solve this problem, a sterilization apparatus (Korean Patent No. 789,325, US Patent Publication No. 2004-013707) using hypochlorous acid having high sterilizing power while being produced in a small amount during electrolysis to produce sodium hypochlorite has been used. .

Hypochlorous acid (HOCL) is hydrogen (H) and the hypochlorite ion in the electrolytic process for producing sodium hypochlorite (NaOCL) (OCL ^-) is generated with. Hypochlorite has about 70 times the sterilizing power of sodium hypochlorite. In addition, hypochlorous acid has a large difference in sterilization power according to hydrogen ion concentration (pH), and has a maximum sterilization power when the pH is 4.3 to 5.9.

Therefore, when sterilizing water is prepared using hypochlorous acid, the sterilizing water having high sterilizing power is produced by using a small amount of hypochlorous acid, and thus the size of the sterilizing water manufacturing apparatus is reduced, and the small amount of sterilizing water is easily moved and stored. It is possible to manufacture without the device according to.

However, hypochlorous acid is not only produced in a small amount, it is difficult to separate it as it is mixed with sodium hypochlorite produced in large quantities.

In addition, hypochlorite has a difference in sterilizing power depending on the hydrogen ion concentration. That is, if the hydrogen ion concentration is out of the range of 4.3 ~ 5.9 with the maximum sterilization power, there was a problem that can not be used to drop the sterilization power is not suitable for sterilization water.

The problem to be solved by the present invention is to provide an electrolytic hypochlorous acid sterilizing water production apparatus for automatically generating sterilizing water having high sterilizing power by generating a hypochlorous acid and sodium hypochlorite separated by electrolysis while the hydrogen ion concentration is controlled. .

The decomposition space 135 is a decomposition partition 133 having at least one partition wall hole 134 and is divided into an anode space 135a and a cathode space 135b. Sodium chloride water is supplied to the anode space 135a and the cathode space 135b, respectively. An electrode 136 is provided in each of the anode space 135a and the cathode space 135b, and the electrode 136 is connected to the power supply 137 to supply power. The power supply 137 supplies the electric power to the electrode 136 installed in the anode space 135a to have the polarity of the anode so as to be the anode electrode 136a, and the cathode to the electrode 136 installed in the cathode space 135b. Power is supplied to have a polarity of to be the cathode electrode 136b. The sodium chloride water introduced into the decomposition space 135 is electrolyzed at the anode electrode 136a and the cathode electrode 136b.

When the sodium chloride water is electrolyzed, it is separated into hydrogen, hypochlorite ions, sodium hypochlorite and hypochlorous acid. In the anode space 135a where the anode electrode 136a is installed, the number of hypochlorous acid electrolyzed in sodium chloride water is located, and in the cathode space 135b where the cathode electrode 136b is installed, sodium hypochlorite that is electrolyzed in the sodium chloride water is located. do. At this time, the electrolysis of the sodium chloride water is made while interchanged in the anode space (135a) and the cathode space (135b) through at least one partition hole 134 installed in the decomposition partition wall (133). The sodium chloride water is supplied at a predetermined amount of power in which the sterilization power of hypochlorous acid in the power supply 137 can be maintained at a maximum of 4.3 to 5.9 depending on the concentration of sodium chloride.

As described above, hypochlorous acid number is located in the anode space 135a, sodium hypochlorite number is located in the cathode space 135b, and the anode space 135a and the cathode space 135b are divided into decomposition partition walls 133. have. Therefore, mixing of hypochlorous acid water and sodium hypochlorite water is prevented. A negative electrode sterilizing water discharge pipe 138 is connected to the negative electrode space 135b to discharge sodium hypochlorite water. Hypochlorite located in the anode space 135a is about 70 times higher in sterilizing power than sodium hypochlorite. Hypochlorite water has a high sterilizing power and can increase the sterilizing effect even with a small amount of use. The positive electrode sterilizing water discharge pipe 138 is connected to the positive electrode space 135a in which the hypochlorous water is collected. The positive electrode sterilizing water discharge pipe 138 discharges the hypochlorous acid water collected in the positive electrode space 135a. A discharge filter 139 is formed in the positive electrode sterilizing water discharge pipe 138 to filter out the hypochlorous acid sterilized water to remove impurities. Therefore, sterilization is performed using hypochlorous acid water with high sterilizing power, thus completing the production of sterilizing water.
