Abstract

The invention provides an ozone generation and purification system. The ozone generation and purification system comprises an oxygen supply device, an ozone generation device, an ozone separation device, a control device and a gas path pipeline; the oxygen supply device can provide oxygen; the ozone generation device can electrolyze oxygen into mixed gas containing oxygen and ozone; the ozone separation device can separate ozone in the mixed gas, and an ozone adsorption device is arranged in the ozone separation device; the oxygen supply device, the ozone generation device and the ozone separation device are sequentially communicated through a gas path pipeline, and the gas path pipeline comprises a plurality of branch pipelines; the control device can control the branch pipelines to be opened or closed, and the control device can regulate and control the air pressure of the plurality of branch pipelines. The ozone adsorption device is arranged in the ozone separation device of the ozone generation and purification system, ozone can be collected, the control device can control the plurality of branch pipelines to be opened or closed, the air pressure of the plurality of branch pipelines is regulated and controlled, increase of the air path pressure is effectively prevented, and the safety coefficient is high.

Description

technical field [0001] The present application relates to the technical field of ozone preparation, in particular to an ozone generation and purification system. Background technique [0002] Molecular beam epitaxy technology is a very advanced scientific research technology for growing thin films. Oxide molecular beam epitaxy technology needs to use ozone to provide oxygen elements for thin films. Since ozone is easy to decompose and difficult to transport, it needs to be produced and used now. [0003] At present, most of the ozone generator products used in the industry use air as the oxygen source for direct electrolysis. Since there is a large amount of nitrogen in the air, the ozone produced by this method is impure and mixed with nitrogen compounds, so it cannot be used for oxidation that requires high vacuum and high purity. thin film growth. Moreover, due to the lack of an ozone collection process, the purpose of preparing and reusing within a period of time canno...
