Description

A device for increasing hydroxyl radicals in ozone water produced by an electrolytic ozone generator

Technical field:

The invention relates to a device for increasing hydroxyl radicals produced by an electrolytic ozone generator to produce ozone water, and belongs to the field of ozone technology and applications.

Background technique:

Ozone water sterilizes and decomposes pollutants in two ways: direct reaction - the new ecological oxygen atoms produced by ozone decomposition directly act on bacteria or pollutants; indirect reaction - the formation of hydroxyl radicals ( OH ) acts on bacteria or pollutants. The direct reaction is selective and slow; the indirect reaction is non-selective, OH (E0=2.8V) has high potential, strong reaction ability and fast speed, and can trigger a chain reaction. The existing ozone water machines simply mix water with ozone gas, so the converted hydroxyl radical (·OH) content is low, and its bactericidal effect and ability to decompose pollutants are limited.

Invention content:

The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art and provide a kind of structure simple and practical, improve sterilization and decompose organic matter ability, improve the device of the hydroxyl free radical of electrolysis ozone generator manufacture ozone water.

The purpose of the present invention can be achieved by the following measures: improve the device for the hydroxyl radicals of the ozone water produced by the electrolytic ozone generator, which includes a pure water replenishment device, the pure water replenishment device is connected to a pure water tank, and the water outlet of the pure water tank is connected to the electrolytic ozone generator The anode water inlet of the electrolytic ozone generator is connected, the cathode drainage and exhaust port of the electrolytic ozone generator is connected to the sewage outlet, the anode gas outlet of the electrolytic ozone generator is connected to the air inlet of the pure water bucket, and the gas outlet of the pure water bucket is connected to the ozone water through a one-way valve. The ozone gas inlet of the mixing tank is connected, and the water inlet on the ozone water mixing tank is connected with the water inlet through a one-way valve and a water inlet solenoid valve. It is characterized in that the outlet of the ozone water mixing tank is connected to the reaction tank through a one-way valve, and the reaction tank is connected to the water outlet. The reaction tank is equipped with a UV lamp, and the UV lamp, water inlet solenoid valve and generator are all connected to the electrical control unit. connect.

In order to further realize the purpose of the present invention, the water inlet is connected to the water inlet of the alkaline water mixing tank through a water inlet solenoid valve and a one-way valve; the water outlet of the alkaline water mixing tank is connected to the reaction tank through a one-way valve, and the alkali Slow-release alkaline particles are arranged in the mixed water tank, and the water inlet solenoid valve is connected with the electric control unit.

Compared with the prior art, the present invention can produce the following positive effects: research has found that under the irradiation of ultraviolet light, ozone water can rapidly produce hydroxyl radicals (OH); ·The generation rate of OH is greatly improved. The study also found that the rate of ozone decomposing in water to produce OH increases with the increase of pH value. When pH<4, the decomposition of ozone in aqueous solution is negligible, and the reaction is mainly to dissolve ozone molecules and reduce them in the treated aqueous solution. When the pH is higher than 4, the decomposition of ozone cannot be ignored. When the pH is higher, the ozone is mainly decomposed into highly reactive substances through a series of chain reactions under the catalysis of ^OH- . free radicals for non-selective oxidative degradation of reducing substances. If the pH value increases by one unit of ozone, the rate of forming OH is about 3 times faster; the present invention adds an alkaline water mixing tank to produce alkaline ozone water; greatly improves the generation rate of OH; and improves the effect of disinfection and sterilization. At the same time, alkaline water also improves the ability of degreasing and decontamination. Therefore, this product is a promising advanced oxidation disinfection and sterilization product.
