Description

Technology Field

[0001] The present invention relates to a combination type chlorine disinfectant water manufacturing device, and more specifically, to a combination type chlorine disinfectant water manufacturing device capable of producing various chlorine disinfectant waters suitable for a specific purpose by appropriately diluting chlorine disinfectant waters produced by a diaphragm type and a diaphragm-free type with a diluent. Background Technology

[0003] Generally, sodium hypochlorite (NaOCl) is a colorless, transparent liquid chlorine-based disinfectant used in sterilization devices at water purification plants and sewage treatment plants, cooling water boilers in general chemical plants, desalination process treated water, cooling water treatment in power plants, drinking water treatment, plant and vegetable processing, meat processing, laundry in swimming pools and paper manufacturing, and as a household bleach.

[0004] The method of manufacturing sodium hypochlorite based on the electrolytic principle of salt water is mainly used to produce sodium hypochlorite (NaOCl).

[0005] As an example, a large amount of salt is precipitated in water of a certain amount and pressure, and this state is maintained for 8 to 24 hours, at which point 28 to 30 percent of the salt is melted. Then, the saturated salt water of a certain amount and pressure, in which the salt is melted, is mixed with a pump or the like to produce a diluted salt solution with a salinity of 2.8 to 3.0 percent. Then, the salt in the diluted salt solution is electrolyzed by a direct current voltage applied to both sides of the electrode plates through a process in which this is passed through an electrolysis device having a series of electrode plates (anode and cathode).

[0006] That is, the 2.8–3.0% diluted brine introduced into the interior of the electrolysis device dissociates into sodium ions (Na+) and chloride ions (Cl-). The chloride ions are oxidized at the anode to become chlorine, and the sodium ions are reduced at the cathode to produce sodium. The produced sodium reacts with water to become sodium hydroxide (NaOH) and hydrogen, and then the chlorine produced at the anode reacts with the sodium hydroxide to produce sodium hypochlorite (NaOCl).

[0007] The sodium hypochlorite produced in this way is used as a safe form of brine for chlorine disinfection or as an oxidizing agent at sites requiring disinfection or oxidation; the production volume and concentration of sodium hypochlorite follow Faraday's law, and the production volume and concentration are determined by the diluted brine, which is a mixture of supplied water and salt water.

[0008] Typically, sodium hypochlorite is manufactured using either a membrane-free or membrane-based method, based on the electrolytic principle of saltwater.

[0009] As an example, a method for producing sodium hypochlorite without a diaphragm is a method of producing mildly acidic hypochlorous acid water by electrolyzing raw water to which 2 to 6% hydrochloric acid has been added in a diaphragm-free electrolytic cell, wherein chloride ions are oxidized at the anode to become chlorine, react with the raw water to produce hypochlorous acid, and are mixed and diluted with a large amount of raw water to produce mildly acidic hypochlorous acid water with a pH of 5.0 to 6.5.

[0010] This method has disadvantages such as a complex device structure and the need for fine adjustment of process conditions, making it difficult to operate; furthermore, because hydrochloric acid must be handled as an electrolyte, it poses a significant risk to users operating it arbitrarily at home.

[0011] As another example, a diaphragm-type method for manufacturing sodium hypochlorite involves placing a diaphragm for separating and collecting electrolytic products, collecting alkaline water and strongly acidic water at the cathode and anode, respectively, to produce hypochlorous acid, or mixing and neutralizing the two collected compositions or supplying separate hydrochloric acid to neutralize them to produce sodium hypochlorite.

[0012] This method has limitations as it is restricted to household applications such as health drinks, skin care, bean sprout or chili pepper cultivation, or kimchi fermentation. Furthermore, it has the disadvantages of being complex, difficult to operate, and expensive, as it requires precise flow rate control to maintain acidic and alkaline water at an appropriate pH, and mixing necessitates the installation of a storage tank to receive and store the generated electrolyzed water, as well as injection metering pumps and stirrers.

[0013] Although such sodium hypochlorite has the advantage of being usable for a wide variety of applications depending on the pH range, the pH of the sodium hypochlorite that can be produced is limited depending on whether the diaphragm-type or non-diaphragm-type method is used and the type of electrolyte. Furthermore, there are shortcomings in consistently supplying sodium hypochlorite at a stable ratio when diluted. Therefore, the present invention aims to devise a method for producing and diluting sodium hypochlorite of various pH values ​​applicable to multiple uses within a single set of devices.

[0016] Accordingly, the present invention has been devised in consideration of these points, and aims to provide a combination type chlorine disinfectant water manufacturing device capable of producing chlorine disinfectant water of a desired concentration for each application by implementing a new type of chlorine disinfectant water manufacturing device in which sodium hypochlorite generated in a diaphragm-free hypochlorite generator and a diaphragm-type hypochlorite generator is appropriately diluted in a hypochlorite diluent during the production of chlorine disinfectant water. This enables the production of sodium hypochlorite of various pH levels usable in various fields, such as strong acidity, weak acidity, and mild acidity, as well as the stable production of chlorine disinfectant water of various concentrations suitable for the intended use. means of solving the problem

[0018] To achieve the above objective, the combination type chlorine disinfectant water production device provided in the present invention has the following features.

[0019] The above-described combined chlorine disinfectant water manufacturing device comprises: a non-diaphragm type hypochlorite generator having a front saltwater inlet and a rear sodium hypochlorite outlet, which generates sodium hypochlorite by electrolyzing saltwater using internal "+" and "-" electrode plates; a diaphragm type hypochlorite generator having a front saltwater inlet and a rear sodium hypochlorite outlet, which generates sodium hypochlorite by electrolyzing saltwater using internal "+" and "-" electrode plates and a diaphragm; a hypochlorite diluent having a front water inlet, a rear chlorine disinfectant water outlet, and two side sodium hypochlorite inlets, which generates chlorine disinfectant water by diluting water and sodium hypochlorite; and components respectively connected between the sodium hypochlorite outlet of the non-diaphragm type hypochlorite generator and one sodium hypochlorite inlet of the hypochlorite diluent, and between the sodium hypochlorite outlet of the diaphragm type hypochlorite generator and another sodium hypochlorite inlet of the hypochlorite diluent. It includes two tubes of sodium hypochlorite.

[0020] Accordingly, the above-described combination type chlorine disinfectant water production device is characterized by the ability to produce chlorine disinfectant water of various concentrations by receiving sodium hypochlorite discharged from a non-diaphragm type hypochlorite generator and sodium hypochlorite discharged from a diaphragm type hypochlorite generator separately or mixed in a hypochlorite diluent, and then diluting them with water.

[0021] Here, an opening and closing valve may be installed at the sodium hypochlorite outlet of the diaphragm-free hypochlorite generator and the sodium hypochlorite outlet of the diaphragm-type hypochlorite generator as a means to control the discharge amount of sodium hypochlorite.

[0022] In addition, the above-mentioned diaphragm-type hypochlorite generator may further include a sodium hydroxide outlet installed parallel to the sodium hypochlorite outlet, having an opening and closing valve.

[0023] As a preferred embodiment, the hypochlorite diluent may include a hypochlorite diluent body having a flow path that is coaxially aligned with a water inlet and a chlorine disinfectant water outlet and is also perpendicularly aligned with a sodium hypochlorite inlet, and a stirring orifice installed in the flow path of the hypochlorite diluent body that rotates by the flow of fluid and induces a vortex.

[0024] As a preferred embodiment, the diaphragm-free hypochlorite generator may include a spacer that supports a "+" electrode plate and a "-" electrode plate stacked and combined in parallel at a certain interval, and maintains the gap between the "+" electrode plate and the "-" electrode plate using a plurality of protrusions, as well as maintains the gap with the inner wall of the hypochlorite generator.

[0025] As a preferred embodiment, the diaphragm-type hypochlorite generator may include a rectangular frame-shaped electrode / diaphragm support plate stacked in a stacked manner, having a "+" electrode plate and a diaphragm or a "-" electrode plate and a diaphragm in an inner empty space, a pair of internal inlets and internal outlets that communicate with a brine inlet, a sodium hypochlorite outlet, and a sodium hydroxide outlet at both ends, and simultaneously communicate with the space to which the "+" electrode plate or the "-" electrode plate belongs, and "+" electrode terminals and "-" electrode terminals connected to the "+" electrode plate and the "-" electrode plate.

[0026] At this time, it is desirable to isolate the pair of internal inlets of the electrode / diaphragm support plates through rubber seals so that the brine supplied from each brine inlet is separated and flows into the space containing the "+" electrode plate and the space containing the "-" electrode plate, respectively, allowing for balanced supply. Effects of the invention

[0028] The combination type chlorine disinfectant water production device provided in the present invention has the following effects.

[0029] First, by applying a new set of chlorine disinfectant water production devices consisting of a combination of a diaphragm-free hypochlorite generator, a diaphragm-type hypochlorite generator, and a hypochlorite diluent, it is possible to produce sodium hypochlorite of various pH levels usable in various fields, such as strong acidity, weak acidity, and mild acidity, and it is effective to consistently and stably produce chlorine disinfectant water of various concentrations and constant ratios suitable for the intended purpose.

[0030] Second, by combining a diaphragm-free hypochlorite generator, a diaphragm-type hypochlorite generator, and a hypochlorite diluent into a single set, the overall structure of the device can be simplified, manufacturing costs can be reduced, and the overall size of the device can be minimized, thereby enabling economical and efficient use tailored to specific applications in various fields.

FIGS. 4 and 5 are a perspective view and a cross-sectional view showing a hypochlorite diluent in a combination type chlorine disinfectant water production device according to an embodiment of the present invention. Specific details for implementing the invention

[0033] The present invention will be described in detail below with reference to the attached drawings.

[0034] FIG. 1 is a perspective view showing a combination type chlorine disinfectant water manufacturing device according to one embodiment of the present invention.

[0035] As illustrated in FIG. 1, the combination type chlorine disinfectant water manufacturing device is a device capable of producing chlorine disinfectant water of various concentrations for use in various fields such as industrial and domestic use by utilizing a combination of a non-diaphragm hypochlorite generator (14) that produces mildly acidic sodium hypochlorite without a diaphragm, a diaphragm hypochlorite generator (16) that produces weakly acidic or strongly acidic sodium hypochlorite with a diaphragm, and a hypochlorite diluent (20) that dilutes the sodium hypochlorite discharged from the non-diaphragm hypochlorite generator (14) and the sodium hypochlorite discharged from the diaphragm hypochlorite generator (16) to an appropriate concentration.

[0036] To this end, the above-mentioned combination chlorine disinfectant water production device includes a diaphragm-free hypochlorite generator (14) as a means of producing sodium hypochlorite by electrolyzing salt water in a diaphragm-free manner.

[0037] In the above-mentioned diaphragm-free hypochlorite generator (14), a salt water inlet (10a) is installed at the front and a sodium hypochlorite outlet (11a) is installed at the rear. Inside the diaphragm-free hypochlorite generator (14), a "+" electrode plate (12a) and a "-" electrode plate (13a) are respectively installed to cause an electrolysis reaction when voltage is applied from the outside.

[0038] Here, the unexplained symbol 27 represents a drain.

[0039] In addition, a manual or solenoid-type opening and closing valve (22) is installed at the sodium hypochlorite outlet (11a) of the above-mentioned diaphragm-free hypochlorite generator (14), and the amount of sodium hypochlorite discharged from the diaphragm-free hypochlorite generator (14) can be controlled by the operation of the opening and closing valve (22).

[0040] Accordingly, when hydrochloric acid or an aqueous solution of sodium chloride added to hydrochloric acid is electrolyzed in a diaphragm-free hypochlorite generator (14), which is a diaphragm-free electrolytic cell, mildly acidic sodium hypochlorite with a pH of about 5.0 to 6.5 can be obtained.

[0041] The structure of such a diaphragm-free hypochlorite generator (14) can be examined in more detail as follows.

[0042] As illustrated in FIG. 2, the diaphragm-free hypochlorite generator (14) comprises a rectangular upper case (14a) having a brine inlet (10a), a sodium hypochlorite outlet (11a), and a drain (27) on the upper surface, a rectangular lower case (14b) having a "+" electrode terminal (33a) and a "-" electrode terminal (34a) on the lower surface, and "+" electrode plates (12a) and "-" electrode plates (13a) installed inside the upper and lower cases (14a, 14b).

[0043] Here, the "+" electrode plate (12a) and the "-" electrode plate (13a) are formed in the form of multiple parallel plates that are alternately arranged between each other, and these multiple plates form a bundle by connecting one end to the other, and each bundle of plates is connected to the "+" electrode terminal (33a) and the "-" electrode terminal (34a) by welding, respectively, so that power can be supplied.

[0044] And, the above-mentioned diaphragm-free hypochlorite generator (14) includes a spacer (30) formed in the shape of a "C".

[0045] These spacers (30) serve to support one side of the "+" electrode plate (12a) and "-" electrode plate (13a) that are stacked and combined side by side at regular intervals, for example, the side of a bundle of plates that is not connected to each other.

[0046] At this time, a plurality of protrusions (29) are formed on the inner surface of the vertical member of the spacer (30), and each of the protrusions (29) formed in this way is fitted between the "+" electrode plate (12a) and the "-" electrode plate (13a), so that the gap between the "+" electrode plate (12a) and the "-" electrode plate (13a) can be maintained at a constant level.

[0047] And, the spacer (30) can be supported in close contact with the inner wall (e.g., the inner wall of the ceiling, floor, and side wall sections) of the upper and lower cases (16a, 16b) using its thickness, thereby maintaining a gap between the "+" electrode plate (12a) and the "-" electrode plate (13a) and the inner wall, while simultaneously creating a space through which fluid can flow.

[0048] Accordingly, when voltage is applied to the "+" electrode plate (12a) and the "-" electrode plate (13a), a membrane-free electrolysis reaction occurs between the "+" electrode plate (12a) and the "-" electrode plate (13a), and hypochlorite ions are generated in the space where the "+" electrode plate (12a) and the "-" electrode plate (13a) facing each other are located. Since the hypochlorite ions generated in this way are chemically unstable, they combine with sodium ions to produce alkaline sodium hypochlorite.

[0049] In addition, the above-mentioned combination type chlorine disinfectant water production device includes a diaphragm type hypochlorite generator (16) as a means of producing sodium hypochlorite by electrolyzing salt water in a diaphragm type.

[0050] In the above diaphragm-type hypochlorite generator (16), a salt water inlet (10b) is installed at the front and a sodium hypochlorite outlet (11b) is installed at the rear. Inside the diaphragm-type hypochlorite generator (16), a "+" electrode plate (12a) and a "-" electrode plate (13a) are each installed to cause an electrolytic reaction when voltage is applied from the outside, and a diaphragm (15) is installed between the "+" electrode plate (12a) and the "-" electrode plate (13a).

[0051] Here, the salt water inlets (10b) of the diaphragm-type hypochlorite generator (16) can be formed as a pair arranged side by side.

[0052] In addition, the above-mentioned diaphragm-type hypochlorite generator (16) is equipped with a sodium hydroxide outlet (23) that is positioned next to the sodium hypochlorite outlet (11b) and has an opening / closing valve (22) at the rear.

[0053] In addition, a manual or solenoid-type opening and closing valve (22) is installed at the sodium hypochlorite outlet (11b) of the diaphragm-type hypochlorite generator (16), and the amount of sodium hypochlorite discharged from the diaphragm-type hypochlorite generator (16) can be controlled by the operation of the opening and closing valve (22).

[0054] Accordingly, when an aqueous sodium chloride solution (table salt, salt water) of about 0.2% or less is electrolyzed in a diaphragm-type hypochlorite generator (16), which is a diaphragm-type electrolytic cell composed of an anode and a cathode separated by a diaphragm, a strongly acidic sodium hypochlorite with about 2.7 or less can be obtained from the anode side, or when an aqueous sodium chloride solution (table salt, salt water) of appropriate concentration is electrolyzed in a diaphragm-type hypochlorite generator (16), which is a diaphragm-type electrolytic cell composed of an anode and a cathode separated by a diaphragm, a weakly acidic sodium hypochlorite with about 2.7 to 5.0 can be obtained from the anode side or from the anode side and the cathode side.

[0055] The structure of such a diaphragm-type hypochlorite generator (16) is described in more detail as follows.

[0056] As illustrated in FIG. 3, the diaphragm-type hypochlorite generator (16) comprises a rectangular upper case (16a) having a sodium hypochlorite outlet (11b) and a sodium hydroxide outlet (23) at the rear end, a lower case (16b) having two brine inlets (10b) at the front end, and a "+" electrode plate (12b), a "-" electrode plate (13b), and a diaphragm (15) installed inside the upper and lower cases (16a, 16b).

[0057] And, several "+" electrode terminals (33b) and "-" electrode terminals (34b) that extend from the "+" electrode plate (12b) and "-" electrode plate (13b) respectively and are exposed to the outside can be connected to the power source by each adapter (37).

[0058] In particular, the above-mentioned diaphragm-type hypochlorite generator (16) includes a plurality of rectangular frame-shaped electrode / diaphragm support plates (35) that are stacked one on top of the other between the upper and lower cases (16a, 16b).

[0059] These electrode / diaphragm support plates (35) are of two types. One type of electrode / diaphragm support plate (35) is structured such that a "+" electrode plate (12b) and a diaphragm (15) are installed side by side with a certain distance between them in an empty space on the inside, and the other type of electrode / diaphragm support plate (35) is structured such that a "-" electrode plate (13b) and a diaphragm (15) are installed side by side with a certain distance between them in an empty space on the inside.

[0060] The two types of electrode / diaphragm support plates (35) made in this way can be alternately stacked between upper and lower cases (16a, 16b) and combined with the upper and lower cases (16a, 16b). In this combined state, the "+" electrode terminals (33b) of the "+" electrode plate (12b) installed on each electrode / diaphragm support plate (35) are exposed to the outside and positioned up and down on one side, and the "-" electrode terminals (34b) of the "-" electrode plate (13b) installed on each electrode / diaphragm support plate (35) are exposed to the outside and positioned up and down on the other side.

[0061] And, at the tip of the electrode / diaphragm support plate (35), a pair of left and right internal inlets (31) are formed that communicate with two saltwater inlets (10b), and each of the internal inlets (31) is connected to the space containing the "+" electrode plate (12b) and the space containing the "-" electrode plate (13b), respectively.

[0062] In addition, a pair of left and right internal outlets (32) are formed at the rear end of the electrode / diaphragm support plate (35) and are connected to the sodium hypochlorite outlet (11b) and the sodium hydroxide outlet (23), and each internal outlet (32) is connected to the space containing the "+" electrode plate (12b) and the space containing the "-" electrode plate (13b), respectively.

[0063] In particular, the left and right pair of internal inlets (31) of the electrode / diaphragm support plate (35) are separated from each other by a rubber seal (36), and accordingly, the saltwater supplied from the two saltwater inlets (10b) is divided into the space where the "+" electrode plate (12b) is located and the space where the "-" electrode plate (13b) is located, and is supplied in a balanced manner while being concentrated in each.

[0064] Of course, the left and right pair of internal outlets (32) of the electrode / diaphragm support plate (35) can also be isolated from each other by a rubber seal (36).

[0065] Accordingly, when a voltage is applied to the "+" electrode plate (12b) and the "-" electrode (13b) arranged with the above diaphragm (15) in between, a diaphragm-type electrolysis reaction occurs between the "+" electrode (12b) and the "-" electrode (13b).

[0066] Subsequently, strong alkaline electrolytic water is generated in the space containing the "-" electrode (13b), and acidic hypochlorous acid water is generated in the space containing the "+" electrode (12b), and eventually, strong acidic sodium hypochlorite with a pH of 3 or lower is generated.

[0067] For example, a sodium chloride aqueous solution of 0.2% or less can be electrolyzed in a diaphragm electrolytic cell space composed of an anode and a cathode separated by a diaphragm to obtain a strongly acidic hypochlorous acid solution from the anode side, and the strongly acidic hypochlorous acid solution obtained in this way can be supplied to the hypochlorite diluent (20).

[0068] Additionally, the above-mentioned combination type chlorine disinfectant water manufacturing device includes a hypochlorite diluent (20) as a means of appropriately diluting sodium hypochlorite supplied from a non-diaphragm type hypochlorite manufacturer (14) and / or a diaphragm type hypochlorite manufacturer (16) with water to produce chlorine disinfectant water of various concentrations.

[0069] As illustrated in FIGS. 4 and 5, the hypochlorite diluent (20) is composed of a hypochlorite diluent body (25) that provides a dilution space for water and sodium hypochlorite, and at least one stirring orifice (26) that stirs the water and sodium hypochlorite so that they can be diluted well.

[0070] The above-mentioned hypochlorite diluter body (25) is in the form of a rectangular block, with a water inlet (17) installed at the front and a chlorine disinfectant water outlet (18) installed at the rear, and in addition, two sodium hypochlorite inlets (19) are installed on the side of the hypochlorite diluter body (25).

[0071] And, inside the above-mentioned hypochlorite diluter body (25), a channel (24) is formed in the shape of a two-stage diameter hole that penetrates in a straight line parallel to the central axis.

[0072] The path (24) formed in this way is connected to the front water inlet (17) and chlorine disinfectant water outlet (18) in a straight line and coaxially, and is connected to the side sodium hypochlorite inlet (19) at a 90° right angle.

[0073] Accordingly, the water entering through the water inlet (17) and the sodium hypochlorite entering through the sodium hypochlorite inlet (19) are mixed in the flow path (24), diluted to an appropriate concentration, and then discharged through the chlorine disinfectant water outlet (18).

[0074] For example, when water entering through the water inlet (17) passes through the interior of the channel (24) at high speed, sodium hypochlorite entering through the sodium hypochlorite inlet (19) is naturally mixed with the water and diluted together by being driven by the flow rate of the water.

[0075] The above stirring orifice (26) is in the form of a disc with a plurality of holes (28) formed through its thickness, and is installed in the flow path (24) of the hypochlorite diluter body (25) to rotate by the flow of fluid and induce a vortex.

[0076] Accordingly, the stirring orifice (26) is freely rotated by the flow of water and sodium hypochlorite entering the interior of the channel (24) from the front and side and proceeding toward the rear, that is, toward the chlorine disinfectant water outlet (18). As the stirring orifice (26) rotates around its own axis inside the channel (24), it is possible to induce a vortex in the flow of water and sodium hypochlorite. Consequently, the stirring of water and sodium hypochlorite is actively carried out by this vortex flow, and the water and sodium hypochlorite can be uniformly and evenly diluted.

[0077] In a preferred embodiment, by controlling the flow rate of water supplied to the hypochlorite diluent (20), the flow rate and / or concentration of sodium hypochlorite, etc., it is possible to produce chlorine disinfectant water of various concentrations according to the purpose of use.

[0078] For example, it is possible to produce a high-concentration chlorine disinfectant solution diluted to a concentration of 100 ppm for washing or disinfecting hands, rags, dishcloths, cutting boards, etc., a medium-concentration chlorine disinfectant solution diluted to a concentration of 50 ppm for washing meat or fish, and a low-concentration chlorine disinfectant solution diluted to a concentration of 30 ppm for washing vegetables or fruits.

[0079] In addition, the above combination type chlorine disinfectant water manufacturing device includes two sodium hypochlorite tubes (21) as a means to allow sodium hypochlorite coming from a non-diaphragm type hypochlorite manufacturer (14) and / or a diaphragm type hypochlorite manufacturer (16) to enter a hypochlorite diluent (20).

[0080] The sodium hypochlorite tube (21) is connected and installed between the sodium hypochlorite outlet (11a) of the diaphragm-free hypochlorite generator (14) and one sodium hypochlorite inlet (19) of the hypochlorite diluent (20), and between the sodium hypochlorite outlet (11b) of the diaphragm-type hypochlorite generator (16) and another sodium hypochlorite inlet (19) of the hypochlorite diluent (20).

[0081] Accordingly, sodium hypochlorite discharged from the sodium hypochlorite outlet (11a) of the diaphragm-free hypochlorite generator (14) and the sodium hypochlorite outlet (11b) of the diaphragm-type hypochlorite generator (16) can enter the flow path (24) of the hypochlorite diluter (20) through each sodium hypochlorite tube (21).

[0082] The usage conditions of the combined chlorine disinfectant water production device configured in this manner are as follows.

[0083] When voltage is applied to the "+" electrode plate (12a) and the "-" electrode plate (13a) in the above-mentioned diaphragm-free hypochlorite generator (14), a diaphragm-free electrolysis reaction occurs between the "+" electrode plate (12a) and the "-" electrode plate (13a).

[0084] Accordingly, hypochlorite ions are generated in the space containing the "+" electrode plate (12a) and the "-" electrode plate (13a) facing each other, and at this time, the hypochlorite ions and sodium ions combine to produce mildly acidic sodium hypochlorite, and the sodium hypochlorite thus produced is supplied to the hypochlorite diluent (20) through the sodium hypochlorite tube (21).

[0085] When voltage is applied to the "+" electrode plate (12b) and the "-" electrode plate (13b) arranged with the diaphragm (15) in between in the above diaphragm-type hypochlorite generator (16), a diaphragm-type electrolysis reaction occurs between the "+" electrode plate (12b0) and the "-" electrode plate (13b).

[0086] Accordingly, strong alkaline electrolytic water is generated in the space containing the "-" electrode plate (13b), and acidic hypochlorous acid water is generated in the space containing the "+" electrode plate (12b). Consequently, strong acidic sodium hypochlorite with a pH of 3 or lower is generated, and the sodium hypochlorite thus generated is supplied to the hypochlorite diluent (20) via the sodium hypochlorite tube (21).

[0087] As an example, a strongly acidic hypochlorous acid solution can be obtained from the anode side by electrolyzing a sodium chloride aqueous solution of 0.2% or less in a diaphragm electrolytic cell composed of an anode and a cathode separated by a diaphragm.

[0088] As another example, the strong basic solution that passed through the above diaphragm (15) is discharged separately, and a weakly acidic hypochlorous acid solution with a pH of about 3 to 5 is generated by reducing Na in the diaphragm-free space.

[0089] By using a manufacturing device in the form of a single assembly that combines a diaphragm type, a diaphragm-free type, and a diluent, strong acidic, weak acidic, and mildly acidic hypochlorous acid water and sodium hypochlorite can be easily produced, and strong alkaline electrolytic water can also be produced simultaneously. In this way, chlorine disinfectant water for various uses can be prepared by easily selecting the pH of the hypochlorous acid water to suit various concentrations for industrial or domestic use and then diluting it.

[0090] In addition, while there is a risk that the sterilization ability of medicinal materials may decrease due to changes in concentration over time following storage or dilution, the manufacturing device provided in this invention is used simultaneously with operation, so the sterilization power can be maintained.

[0091] Furthermore, since the manufacturing device of the present invention uses inexpensive refined edible salt as a raw material, it not only saves on the cost of producing sterilized water and ensures excellent hygiene management, but also places no burden on the environment because it uses only natural ingredients such as salt and water, making it safe for the human body and naturally biodegradable.

[0092] Thus, the present invention provides a new chlorine disinfectant water production device capable of producing chlorine disinfectant water of a desired concentration for each application by appropriately diluting sodium hypochlorite produced in a diaphragm-free hypochlorite production device and a diaphragm-type hypochlorite production device in a hypochlorite diluent. This enables the production of sodium hypochlorite of various pH values ​​usable in various fields, such as strong acidity, weak acidity, and mild acidity, and allows for the stable production of chlorine disinfectant water of various concentrations suitable for the intended use at all times. Furthermore, it simplifies the structure of the device and enables the device to be manufactured compactly at a low cost. Explanation of the symbols
