Abstract

The invention relates to a device for preparing high-concentration ozone and recycling residual oxygen. According to the invention, oxygen is adopted as a raw material, and ozone is prepared through corona discharge. The device comprises an oxygen buffering tank (1), an ozone generator (2), a mixed gas buffering tank (3), a pressure swing adsorption tower A (4), a pressure swing adsorption tower B (5), and an ozone storage tank (14). The oxygen buffering tank (1) is connected with the ozone generator (2). The ozone generator (2) is connected with the mixed gas buffering tank (3). The mixed gas buffering tank (3) is connected with the pressure swing adsorption towers. Oxygen outlets of the pressure swing adsorption tower A (4) and the pressure swing adsorption tower B (5) are connected with the oxygen buffering tank (1). Ozone outlets of the pressure swing adsorption tower A (4) and the pressure swing adsorption tower B (5) are connected with the ozone storage tank (14). The device provided by the invention has the advantages that: ozone and oxygen are absorbed and separated by the pressure swing adsorption towers; the concentration of obtained ozone is high; oxygen utilization rate is high; and device structure is simple.

Description

technical field [0001] The invention relates to a device for producing ozone by using oxygen as a raw material through corona discharge, especially for producing high-concentration ozone and recovering and reusing residual oxygen. Background technique [0002] At present, ozone has been widely used in water treatment, medicine, food industry and many other fields. At present, there are two main methods for preparing ozone: one is electrolysis, direct current electrolysis of pure water, and the hydrogen and oxygen obtained by electrolysis are separated by membrane technology. , so as to obtain ozone; the other is high-voltage corona discharge to obtain ozone. The ozone concentration obtained by these two methods is very low. The ozone content of the former is about 20%, and the remaining 80% is oxygen; the ozone content of the latter is lower, with oxygen as the raw material, the ozone content is about 10%, and the remaining 90% is oxygen. If air is used as the raw material,...
