Abstract

The invention belongs to the technical field of ozone generation, and discloses a semi-wet high-efficient ozone generation method and device. In the ozone generation method, ozone is generated under a semi-wet environment by combining pulse discharge technique of converting oxygen molecules and a part of water molecular into ozone. The device is composed of a pulse charger, an air inlet pipe, and an ozone generator. Oxygen and water are input into the air inlet pipe at the same time to form a high-speed oxygen-water mist mixture; the mixture enters the ozone generator; under the action of a series of pulse discharge, the oxygen and a part of water are converted into ozone for output; and water vapor mixed in the ozone is removed via condensation separation. According to the method and device, the electric energy efficiency is obviously improved, and the ozone can be output in a high concentration.

Description

technical field [0001] The invention belongs to the technical field of ozone generation, and in particular relates to a semi-wet type high-efficiency ozone generation method and device. Background technique [0002] As a strong oxidant, ozone has strong disinfection and oxidative decomposition capabilities, and is widely used in drinking water treatment, domestic sewage and industrial wastewater treatment. Compared with other oxidants, ozone disinfection and oxidation are rapid, and the product of ozone decomposition and reduction is oxygen, which is a green and efficient oxidant. At present, the methods for producing ozone are high-voltage discharge method, electrolysis method, and ultraviolet light irradiation method. The high-voltage discharge method has a large ozone output and is most widely used in industry. Theoretically, 1220g of ozone can be generated by consuming 1kWh of electricity. However, in the actual production process, the ozone produced by consuming 1kWh o...
