Abstract
The present invention, unlike traditional acid oxidized potential water preparing process, needs no tap water softening unit and ionic isolating film and produces no alkali waste water. The technological process includes pumping with metering pump electrolysis additive solution with certain concentration of sodium chloride and hydrochloric acid into electrolytic bath; electrolysis to produce water containing dissolved oxygen, effective chlorine and hydrochloric acid; and mixing the electrolytic water and tap water for dilution and further reaction to produce acid oxidized potential water with high oxidation-reduction potential, low pH value and low effective chlorine concentration.
Description
Technical Field
The electrolyzed oxidizing water generator is a device for generating electrolyzed oxidizing water by an electrolysis technology, adopts a brand new electrolysis technology, does not need an ion diaphragm and a tap water softening device, and directly electrolyzes tap water and an electrolysis additive solution to generate the electrolyzed oxidizing water.
Background
The acidic electrolyzed oxidizing water (also called as strong acidic water, electrolyzed oxidizing water, functional water, etc.) is water with high oxidation-reduction potential (ORP is usually between 1050 and 1180 mV), low pH (PH value is usually less than 2.7) and low effective chlorine concentration (concentration is usually 10-50mg/L), and the water has stronger oxidizing ability and rapid microorganism killing effect.
The working principle of the traditional acidic oxidation potential water device is as follows: adding 0.05% NaCl into tap water, and oxidizing with acidic electrolyzed water to obtain the final productThe combined electrolytic tank with ionic diaphragm is formed by electrolysis. Since the ion membrane separates the anode side and the cathode side of the electrolysis cell. The salt solution is dissociated into H by electrolysis+And OH-And OH-The positive electron bonded to the anode side becomes OH 4OH to water and oxygen, and 4H remains in the anode side of the cell+H is accumulated in the anode groove separated by the diaphragm+Therefore, the water obtained from the anode tank will exhibit acidity. The anode is made of chloride ion (Cl)-) Chlorine gas is formed and then further reacted with H2The O reaction generates hydrochloric acid and hypochlorous acid (HClO), so that the water obtained from the anode tank contains 10-50mg/L of available chlorine.
In addition at the anode H2O is also electrolyzed into oxygen (O)2) And hydrogen ions, as a result, the pH value of the water obtained in the anode tank is below 2.7, the effective chlorine concentration reaches 10-50mg/L, and the dissolved oxygen and the oxidation-reduction potential are remarkably increased, generally between 1050-1180 mV.
However, the electrolyzed oxidizing water apparatus has the following disadvantages: 1. because the electrolytic bath is divided into the acidic water tank and the alkaline water tank by the ionic membrane, only acidic water is useful, and alkaline water is waste water, so that not only a water source but also electric energy are wasted; 2. ion diaphragms are very expensive to manufacture; 3. since particles, impurities, suspended matters and ions with large diameters such as calcium and magnesium ions in tap water are easy to block the ion diaphragm, in order to avoid the phenomenon, the tap water needs to be filtered and softened before entering an electrolytic cell, and the cost is high.
Disclosure of Invention
In order to overcome the defects of complex structure, high cost (needing an ion diaphragm and a tap water softening device), water and electricity waste (containing alkaline waste water) and the like of the traditional electrolyzed oxidizing water device, the invention adopts a novel diaphragm-free electrolysis technology which is simple and easy to operate, and the generated electrolyzed oxidizing water has the same effect as the electrolyzed oxidizing water generated by the traditional electrolyzed oxidizing water device.
The technical scheme adopted by the invention for solving the technical problems is as follows: the electrolyte additive solution containing the mixed solution of sodium chloride and hydrochloric acid is electrolyzed in an electrolytic bath with anode and cathode. Water dissociation into H by electrolysis+And OH-And OH-Binding to the anode side to obtain positive electrons, which become OH, which are decomposed into water and oxygen (ii) a The anode is made of chloride ion (Cl)-) Chlorine gas is formed and then further reacted with H2The O reaction generates hydrochloric acid and hypochlorous acid (HClO), so that the generated acidic oxidation potential water contains 10-50mg/L of available chlorine; electrolysis of H in additive solution+Controlling the pH value of the acidic oxidation potential water to be below 2.7; dissolved oxygen and hypochlorous acid (HClO) in the water cause a significant rise in the redox potential, typically between 1050-1180 mV.
The beneficial effects of the invention are as follows: tap water does not need to be softened and can be directly used after primary filtration; an ion diaphragm is not needed in the electrolytic cell, and the electrolytic cell is not needed to be divided into an anode cell and a cathode cell; the generated water is all acidic oxidation potential water, and no alkaline wastewater is generated; the electrolysis additive solution containing the mixed solution of sodium chloride and hydrochloric acid is directly electrolyzed and then diluted with tap water, and the structure is simple.

Detailed Description

The effective chlorine concentration of the electrolyzed oxidizing water is adjusted through the current, the speed of a metering pump and the flow rate of tap water; the pH value of the acidic oxidation potential water is controlled by adjusting the concentration of the hydrochloric acid in the electrolytic additive solution, the speed of a metering pump and the flow rate of tap water.
