In order to achieve the above object, the present invention uses a negative electrode made of titanium and a DSA insoluble electrode coated with iridium on titanium, and is a cylindrical new electrolytic reactor provided with a porous ceramic membrane between the electrodes. Next, the cylindrical ceramic membrane is composed of a negative electrode, followed by a plurality of electrolytic reactors, in which the surface of the electrode is maximized, so that a sufficient amount of acidic and alkaline water can be produced in one operation. It is characterized by that.

In addition, the present invention adopts a device for circulating the negative electrolyte to allow the electrolytic reaction to occur continuously by repeating the electrolyzed negative electrolyte solution, even when saturated brine is used to minimize the loss of brine and also to increase the concentration of alkaline water As it can be adjusted to the required degree, it has the characteristic of increasing the electrolysis efficiency very much. In other words. Compared to the existing technology without the recycling of electrolytic solution, even though saturated brine with a very high concentration is used, there is no loss of brine and it is economical and the electrolyte concentration can be adjusted. It has economic and technical significance.

The present invention is composed of a portion for recovering or cooling recovery of the electrolytic reactor and the deodorizing sterilization water to generate the deodorizing sterilization water.

Hereinafter, the configuration of the present invention in more detail with reference to the accompanying drawings as follows. However, since the accompanying drawings are only examples shown to specifically describe the technical idea of the present invention, the technical idea of the present invention is not limited to the form of the accompanying drawings.

First, the structure of the electrolytic reactor which is a structural unit of the present invention will be described with reference to FIGS.

Figure 1 shows a vertically sheared side of the drawing of the electrolytic reactor assembled in accordance with a preferred embodiment of the present invention and Figure 2 is to illustrate this in three-dimensional cross-section to facilitate understanding.

The electrolytic reactor 26 has a cylindrical shape with an internal positive electrode 10, the outside of which is surrounded by a porous cylindrical ceramic film 7 and a cylindrical negative electrode 5 on the outer side thereof. There is a space between the positive electrode 10 and the ceramic film 7, which is a positive electrolytic chamber 8 and a negative electrolytic chamber 6 between the ceramic film 7 and the negative electrode 5. The upper and lower sides are symmetrical, and the upper and lower sides are the same shape, and the upper and lower positive and negative charge chamber inlets and outlets 3 and 3a and the upper and lower negative electrolyte compartment inlets and outlets 4 and 4a connected to the positive and negative charge chambers 8 and the outside thereof, and And an outer fixing head 15, an inner fixing head 16, and an auxiliary head 17 made of plastic material to fix the positive electrode 10, the negative electrode 5, and the ceramic film 7. . In addition, the positive electrode hole 9 is formed in the positive electrode 10 so that the positive charge chamber and the brine in the positive electrode are distributed so that the positive electrode liquid moves to the positive electrolyte chamber. The terminal 2 is located in the middle.

The negative electrode is made of titanium material, and the positive electrode is made of DSA insoluble electrode made of titanium coated with iridium to suppress oxidation or corrosion. In particular, since the present invention is designed to use saturated salt water, when the DSA insoluble electrode is not used in the positive electrode, the lifetime of the electrolytic reactor may be shortened due to corrosion or oxidation, and thus there is no practicality.

3 illustrates the coupling relationship of the electrolytic reactor.

The electrolytic reactor first assembles the auxiliary plate 13, the connection nut 12, the positive electrode terminal 1, and the other connection nut 11 at an appropriate height in the support tube 14, and then the external fixing head 15, the internal The fixed head 16 and the auxiliary head 17 and the O-ring 18 are sequentially sequentially assembled, and then some of the fastened devices are turned up and down, and then sequentially tightened in the reverse order to tightly coupled with the electrolytic reactor 26. ).

The electrolytic reaction path of the brine in the electrolytic reactor and the migration path of the generated acidic and alkaline water are as follows.

The salt solution flows into the positive electrode 10 through the lower positive electrolytic chamber inlet 3a, enters the positive electrolytic chamber 8 through the positive electrode hole 9, and undergoes an electrolysis reaction to form acidic water. Water and natrion ions which have passed through the porous ceramic membrane 7 by pressure flow into the negative electrolytic chamber 6 to continue the electrolytic decomposition reaction. The positive electrolyte in the positive electrolyte chamber is moved to the upper collector 31 (see FIG. 5) through the upper positive electrolyte chamber outlet 3, and the negative electrolyte in the negative electrolyte chamber is circulated through the negative electrolyte chamber 4 It is transferred to the unit 22 (see FIGS. 4 and 5) and stored in a separate reservoir as required by the cooling process. In FIG. 2, when power is applied through the positive electrode terminal 1 and the negative electrode terminal 2, the power is applied from the positive electrode terminal 1 to the positive electrode along the support tube 14, which is a metal conductor, and the negative electrode terminal 2. The negative electrode is applied from the positive electrode chamber 8 and the negative electrode chamber 6 to cause electrolysis reaction, so that acidic water is generated in the positive electrode chamber and alkaline water is generated in the negative electrode chamber.

At this time, when electricity is applied, the reaction in the negative charge chamber is

2H ₂ O + 2Na ⁺ + 2e → 2NaOH + H ₂

_{2H 2 O + 2e → H 2} + 2OH -

ego,

The reaction that occurs at the positive electrode

2Cl ^-- 2e → Cl ₂

2H ₂ O-4e → 4H ⁺ + O ₂

Cl ₂ + H ₂ O ↔ HClO + HCl.

Here, the negative electrode in the pH of the -900mV at about -700 ORP (oxidation reduction potential) of 9 or more, the active ingredients are NaOH, O ₂ ^- and, ₂ and HO, HO ₂ ^-, OH ^-, and OH, HO ₂ ^- ,.

The positive electrode produces a strong acid solution with a pH of 2-3 and an ORP of +800 to + 1200mV. HClO, ClO, as active ingredient yiyongaek ln ^-, O _3, and a HO, HO ₂ and.

Can be applied as needed, the same solution as above is produced by the present invention, for example NaOH, O ₂ generated in the negative electrode ^- and, HO ₂ and, HO ₂ ^-, OH ^- OH and, HO ₂ ^- are steel It can be used to neutralize or reduce acidic gas such as hydrogen sulfide, methyl mercaptan and the like as alkaline solution. On the other hand, mixing an oxidizing agent generated in the cathode HClO, ClO ^-, O _3, and HO, HO ₂ and the like may be used to remove by oxidation of ammonia that is a basic gas, trimethylamine gas. It is important to mist spray them so that they do not diffuse or disperse into the air with oxidation and reduction to produce any secondary pollutants.

In addition, the mixed oxidant solution may be added to water to sterilize bacteria or bacteria, such as bacteria in the water, or may be used to continuously sterilize in water by sustainability. At this time, the solution produced in the negative electrode may be used by mixing to neutralize the acidity of the mixed oxidant.

4 and 5 show the cross-section of the completed device of the present invention and the three-dimensional cross-section thereof showing an example in which four electrolytic reactors 26 are installed, and four or more electrolytic reactors 26 are provided as necessary. It will be appreciated by those skilled in the art that it may be possible.

4 and 5 illustrate the apparatus of the present invention, in which a set of four electrolytic reactors 26 is provided, and the upper and lower collectors 31 and 29 and the cooler 27 are installed in the lower part of the negative electrolyte circulation unit ( The apparatus of the present invention for producing oxidized water and reduced water having 22) as main components is shown.

Specifically, the negative electrolyte circulating part 22 functions as a kind of heat exchanger having a cooler 27 having a cooling function at a lower portion thereof, and the negative electrolyte circulating tube 23 passes through the tube 23. When the negative electrolyte solution (alkaline water) introduced by the pressure from the negative electrolytic chamber outlet 4 of the electrolytic reactor through the negative electrode connecting tube 25 flows up and becomes higher than the height of the negative electrolytic solution circulation tube 23 , And some are collected in the lower collector 29 along the negative electrolyte circulation tube 23 and circulated back to the negative electrolyte chamber 6, and some are collected in the separate reservoir through the alkaline water outlet 33. It will be used, together with the hydrogen discharged to the alkaline water outlet 33 is sent to the outside. That is, the negative electrolyte passing through the negative electrolytic chamber 6 in the four electrolytic reactors 26 is collected through the negative electrode connecting tube 25 to the negative electrolyte circulating part 22 and through the upper negative electrolytic solution circulating tube 23. It cools down in the cooler 22 while descending to the lower part, and is circulated by the natural circulation boiler principle through the negative electrolytic chamber collector 28 and flows into the negative electrolytic chamber 6 again, and part of the alkaline water outlet 33 together with hydrogen is discharged. Discharged.

The cooler 27 enters the coolant into the lower coolant inlet 38 and discharges the coolant to the coolant outlet 35. The circulation is cooled by a conventional method of circulating CW or coolant using a circulating pump (not shown). do.

The brine (salt water) enters the positive electrolyte chamber 8 of the four electrolytic reactors 26 through the lower collector 29 through the salt solution supply port 30, and part of the brine enters the porous ceramic membrane 7 Through the negative charge chamber 6 is introduced. The brine solution passed through the positive electrolyte chamber of the electrolytic reactor 26 may use a saturated solution and the acidic water, which is a mixed oxidant generated, is collected in the upper collector 31 through the connecting tube 24 and the mixed oxidant outlet 32 is opened. Collected through a constant tank. Air is discharged through the upper collector exhaust port 21 for cleaning the electrolytic reactor, and the internal solution may be discharged through the drain valve. In particular, in the case of using only alkaline discharge water, the amount of brine flowing into the positive electrolyte chamber 8 is filled up to a certain height, and the negative electrolyte in the negative electrolyte chamber 6 is continuously charged through the negative electrode connecting tube 25. (22) is cooled down in the cooler (27) while descending to the lower through the upper negative electrolytic solution circulation tube (23) and is circulated by the natural circulation boiler principle through the negative electrolytic chamber collector (28) of the negative electrolytic solution To increase the conversion rate, and therefore, using a high concentration of saturated brine to increase the conversion rate and thus there is an advantage that can also save power.

In addition, as another example of the present invention, in the case of using only sterilized water, the above apparatus may be partially modified and described in detail with reference to FIG. 6. 6 is basically a sterilization apparatus composed of one set of the same four electrolytic reactors as in FIG. 4. For convenience, the shape of the electrolytic reactor combined with one electrolytic reactor is briefly illustrated. It can be easily seen from FIG. 4 that it is comprised by the set.

6 shows a negative electrolyte solution from a plurality of electrolytic reactors 26 and a negative electrolytic chamber 6 of a plurality of electrolytic reactors (four are used in the present invention, but the number of electrolytic reactors is not limited). Part of the negative electrolytic solution introduced into the unit 51 falls down through the inner tube 52 penetrating through the diaphragm 42 and is collected in the negative electrolytic chamber collector 53 and is negative again by a natural circulation method. Some of the other negative electrolyte flowing into the electrolytic chamber 6 and introduced into the negative electrolyte inlet 51 may include chlorine gas introduced from the positive electrolyte chamber 8 in the mixing chamber 54 through the inlet hole 55. The water inlet pipe 60 through the cooling pipe 56 is mixed with the cooling water introduced through the inlet pipe 59 is made in such a way that the sterilization solution is generated. In the above apparatus, the movement of the negative electrolyte from the positive charge chamber of the electrolytic reactor to the negative charge chamber is caused by the back pressure because the chlorine gas generated in the positive charge chamber 8 passes through the narrow connecting pipe 58. The mass transfer takes place and eventually is mixed in the mixing chamber 54 to flow out to the outlet (57).

At this time, the chemical reaction occurring in the mixing chamber 54 is considered to proceed as follows.

Cl ₂ + H ₂ O ↔ HOCl + HCl

HOCl + HCl + 2 NaOH ↔ Na + OC - - + NaCl + 2H 2 O

Therefore, the generated hypochlorous acid (LOX) can be used as sterilized water, so that it can be stored in the storage tank through the outlet 57 in the mixing chamber 54, if necessary, and then used at the required place and time.

FIG. 7 illustrates another embodiment of the present invention, which is implemented in a form having a plurality of electrolytic reactors 26 (four in the drawing), the mixing chamber 54 connected to the electrolytic reactor as shown in FIG. 5, The negative electrolyte inlet 51 and the negative electrolyte chamber 53 are implemented in an independent form so as to correspond to the respective electrolytic reactors 26. However, the positive electrolyte chamber inlet 3a (see FIG. 2) formed in each of the electrolytic reactors 26 to supply the salt solution through one salt solution supply port 30 as shown in FIG. Is connected by the positive electrode compartment outlet 3 is connected by the upper collector (31). In addition, the means for cooling is connected by a tube to have one coolant inlet 38 and one coolant outlet 35, and has a structure of a mixing chamber 22a in the form of a tube. Since the internal structure has a structure as shown in FIG. 5, no detailed structure is described. In addition, according to the structure of Figure 7 it will be obvious to those skilled in the art will also be easily modified if having an internal structure as shown in FIG.

The present invention relates to an apparatus for generating deodorizing sterilization water, which generates deodorizing sterilization water in the field, and sprays ionic gas into ionic gas as necessary to remove odor in oxidation or reduction, while not generating secondary by-products. do. It can be used according to the kind of gas to be generated and removed by generating salt deodorized water with salt solution only in the field. Especially, it can be used for water treatment such as drinking water, swimming pool and cooling tower as sterilization water. Since the generated water is a odorant or a mixture widely used in water treatment, safety is already secured.
