Description

Production system for hypochlorons acid

The present invention relates to a dental chloric acid generation system for effectively sterilizing objects hygienically, ranging from drinking water such as drinking water, to food and medicine, and particularly, through plate electrodes having holes having a predetermined diameter (about 4 to 5 mm). As the discharge time of the aqueous solution in which the electrolyte solution (NaCl + HCl) and the tap water (H ₂ O) are mixed is controlled, the generation of hypochlorons acid (HOCl) can be more easily performed through electrolysis of the naturally circulating aqueous solution. It relates to a production system of dental chloric acid.

Conventionally, in addition to chlorine (Cl ₂ ) produced by electrolysis of salt for disinfection of various drinking water, drinking water, food, etc., including tap water, hypochlorite (NaOCl), hypochlorite (CaCOCl · 2H ₂ O) Chlorination has been done in the form.

In addition, chlorine chloride (HOCl) has a sterilizing effect, but it has not been used in mass production and manufacturing, and no method and apparatus have been proposed that can be efficiently used for the method and apparatus.

In addition, chlorine gas (Cl ₂ ) is inconvenient to store, and because it is obtained and used in the gas phase, not only was very dangerous to handle, but also had a low sterilizing effect.

In the prior art, but performing the sterilization by using an electrode with a diaphragm membrane between a cathode and an anode with saline to eliminate the same problem described above, the tooth sodium hypochlorite (OCl ^-) are disinfection of 1/80 compared to the hypochlorous acid (HOCl) Therefore, it is manufactured as an aqueous solution of 4% (4000ppm) or more according to the law and is used as disinfectant water.

At this time, since the use of a high concentration of aqueous solution flows into the sewage after use of the aqueous solution causes environmental pollution, there was no environmental pollution could not be easily used to prepare disinfectant sterilized water at home.

In the related art, when an electrolyte solution (NaCl + HCl) and tap water (H ₂ O) are introduced into an electrolytic cell, an aqueous solution consisting of a mixture of electrolyte solution and tap water is made by pumping the pump, and then power is supplied to the mesh electrode. The present invention provides an apparatus for producing desired sterilized water (chlorochloric acid) through electrolysis of an aqueous solution mixed in the electrolytic cell.

However, the chlorine acid generation system as described above is a structure in which the aqueous solution is forcedly circulated through the mesh electrode by the driving of the pump, and when the circulation rate of the forced circulating aqueous solution proceeds rapidly, electrochlorination cannot be performed at one time. In the case of the mesh electrode, the maintenance of the chlorine acid generation system adds a considerable cost.

In addition, the conventional chlorine acid generation system has been proposed to allow the introduction of tap water automatically from the opening and closing of the automatic valve in which the time is set in the electrolytic cell, while the pumping of the pump is proposed to be made automatically for the set time. This was followed by the inconvenience that the production of chloric acid was not continuous.

Here, look at in more detail with respect to the hypochlorous acid as follows.

Hypochlorite has been reported to have no toxicity through acute toxicity test, eye irritation test, primary skin irritation test, skin cumulative irritation test, sensory test, cytotoxicity test, mutagenicity test.

In such chlorine acid, chlorine gas (Cl ₂ ) is produced by electrolyzing sodium chloride (NaCl), which is a main component such as salt, and when salt water is electrolyzed in an electrolytic cell,

2NaCl + 2H ₂ O → 2NaOH + Cl ₂ ↑ + H ₂ ↑,

When the chlorine gas generated here are water reactive, Cl _2, HOCl, OCl ^-, and be present in the form of, which Cl _2, HOCl, OCl, depending on the pH value exponent (pH) ^- has been found to the existing ratio of Varies .

In other words, it was found that pH is usually present in the form of Cl ₂ in acid, HOCl in neutral, and OCl ⁻ in alkali.

In the case of double hypochlorous acid (HOCl) OCl ^- it has a bactericidal with.

_{Cl 2 + H 2 O ↔HOCl +} H + + Cl -

HOCl ↔H ^{+ +} OCl ^-

_{Ca (OCl) 2 · 2H 2} O → Ca + + 2OCl -

HOCl concentration change according to the above pH is shown in FIG.

Looking at Figure 1, it can be seen that the most effective chlorine (HOCl) abundance ratio when the pH is 5-7.

In particular, when pH = 5.5, it can be seen that it is present in the form of almost 100% of hypochlorite (HOCl).

For example, at pH = 9, since the form of HOCl is 4% and the form of OCl ⁻ is 97%, it is most effective to adjust the pH near 5.5 to exist in the form of HOCl close to 100%.

On the other hand, HOCl in water inhibits the metabolic reaction of the microorganism by the oxidation reaction, chlorination reaction, bringing a bactericidal effect.

That is, R-H + HOCl → R-OH + HCl (oxidation reaction)

RH + HOCL → R-Cl + H ₂ O (chlorination)

Furthermore, chlorine hypochlorite (HOCl) is more toxic and safer than glutaruru, poppiedon, ethanol, cresol, and phenol, which are currently used as fungicides.

On the other ^{_{hand, CaCl 2 · Ca (OCl -}} ) 2 · 2H 2 O ( commercial product has a concentration of 33-38%) is in the water, ^{_{Ca (OCl 2) → 2Ca +}} 2OCl - and a, NaOCl FIG Na → Na ⁺ + of the water OCl ^- there is the ionization chamber to the OCl ^- in order to increase the sterilizing effect is lowered, so when in the form germicidal FIG 1/80 compared with the HOCl form OCl ^- is used, the concentration of more than 4000rpm and has the drawback of involving the end toxicity .

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to add an aqueous solution in which an electrolyte solution (NaCl + HCl) and tap water (H ₂ O) are mixed into an electrolytic cell having a sensor for detecting a water level. After making this automatic, the bottom surface of the electrolytic cell is configured to form a plate electrode having a hole having a predetermined diameter (about 4 to 5 mm) to maintain the discharge time constantly while naturally circulating the aqueous solution. Through the electrolysis of the naturally circulating aqueous solution, it is possible to continuously produce HOCl, which has high sterilizing power at low concentrations, as well as the cost of maintaining the chlorine acid generation system generated when the conventional mesh electrode is applied. To provide a system for the production of chloric acid that can reduce the amount of chlorine.
