Problems solved by technology

In addition, ozone is an insoluble gas, and its solubility in water is low. Using the current commercial ozone gas generator, the highest concentration of ozone water prepared by the above method is about 20mg / L, which greatly limits the application of high-concentration ozone water

Embodiment 1

[0044] In this embodiment, high-concentration ozone water is prepared by dissolving ozone gas under 1 atmospheric pressure.

[0045] Install a three-way valve at the inlet of the booster pump, and connect the three-way valve with the outlet valve on the water storage tank and the ozone water generation tank. By adjusting the three-way valve, the booster pump inlet can be placed between the water storage tank and the ozone water generation tank. to switch. A water inlet check valve is installed at the outlet of the booster pump, and a water inlet valve is installed on the ozone water generating tank. The water inlet check valve and the water inlet valve are connected to prevent the gas in the tank from flowing backward from the water inlet. Install a variable-diameter nozzle in the ozone water generating tank and connect it with the water inlet valve on the tank. The volume of the ozone water generation tank is 10L.

Abstract

The invention discloses a method and a device for intermittently preparing high-concentration ozone water. The method is as follows: vacuumize the ozone water generating tank and fill it with ozone gas, then water enters the variable-diameter nozzle provided in the ozone water generating tank through a booster pump, and sprays into the ozone water generating tank in the form of micron-sized droplets The ozone gas is efficiently dissolved in the tank; finally, the residual ozone gas is completely dissolved through the internal circulation of the water in the ozone water generating tank to obtain high-concentration ozone water. The method of the invention is simple, the equipment cost is low, and it is easy to implement, and can be implemented by using a common commercial ozone gas generating device. Compared with the conventional ozone mixed gas-dissolving method, the invention has the advantages of high gas-dissolving efficiency, low energy consumption, no loss of ozone gas, and high concentration of prepared ozone water. The invention adopts the method of generating tanks for ozone water, has no residual ozone gas, avoids the use of an ozone tail gas decomposer, has simple equipment, and can prepare high-concentration ozone water on a large scale.

Description

technical field [0001] The invention relates to the technical field of ozone utilization, in particular to a preparation method and device for high-concentration ozone water. Background technique [0002] Ozone is a highly active gas, slightly soluble in water, and it is also a strong oxidant with an oxidation potential of 2.07V. The strong oxidizing property of ozone makes it rapidly sterilize and disinfect, and its disinfection ability is better than that of chlorine, chlorine dioxide and chloramine. In addition, as water sources are polluted by organic chemical industrial products, chlorinated organic compounds such as chloroform, dichloromethane, and carbon tetrachloride will be produced after chlorine disinfection of water. These substances are carcinogenic, while ozone disinfection of water does not produce secondary pollution compound. It takes 1-2 hours for ozone to sterilize in the air, but only a few minutes in water. Therefore, objects that can be sterilized wi...
