Problems solved by technology

However, although the increase in the size of the reactor can significantly increase the ozone production and this method is also commonly used in industrial and agricultural production, for applications that require on-site ozone treatment, the increase in the size of the reactor will significantly increase the size of the ozone generator. Difficulty in operation and transportation

Abstract

The invention discloses a novel discharge module based on surface catalytic film enhanced ozone synthesis. The novel discharge module comprises a discharge unit package board, a venting element I sleeving an air inlet end of the discharge unit package board and a venting element II sleeving a gas outlet end of the discharge unit package board. The discharge unit package board comprises a sealing plate I and a sealing plate II. The lower surface of the sealing plate I is provided with a groove I. The upper surface of the sealing plate II is provided with a groove II corresponding to the grooveI. The groove I is opposite to the groove II. The sealing plate I and the sealing plate II are bonded through tops of groove walls of the groove I and the groove II. A discharge unit is arranged in aspace formed from the groove I and the groove II. A semiconductor film is electroplated on the lower surface of a dielectric plate 1 with a sheet metal electrode and / or the surface of a grid-shaped metal electrode, and in oxygen-containing gas as a gas source, the ozone synthesis is further promoted through a series of heterogeneous reactions in contact with plasma because of a large specific surface area.

Description

technical field [0001] The invention relates to an ozone synthesis module, in particular to a discharge module based on a surface catalytic film to enhance ozone synthesis. Background technique [0002] As a recognized green strong oxidant, ozone is widely used in industrial and agricultural production such as sewage treatment and air purification, and the effect is remarkable. [0003] Recently, with the rapid development of industrial and agricultural production, the environmental pollution problems to be dealt with have become more and more serious, which has correspondingly increased the demand for ozone, thus putting forward higher requirements for the ozone synthesis performance of the ozone generator. As far as the commonly used dielectric barrier discharge ozone generator is concerned, increasing the size of the reactor and rationally designing the electrode structure can effectively increase the ozone production. However, although the increase in the size of the re...
