Abstract

The present invention provides a discharge electrode and a photocatalyst reaction device, which utilizes a three-dimensional discharge electrode that discharges effectively and stably, the relationship between the discharge light emitted from the discharge electrode and the photocatalyst, and can effectively, long-term, and stably remove harmful substances. The discharge electrode is a three-dimensional electrode. The main body (3) of the honeycomb electrode is formed of a conductive film. The shape is honeycomb when viewed from the front and back. Gases containing harmful substances can pass from the front to the back. The sides of the electrode are conductive. The casing (4) covers the electrode and has a specified thickness in the direction from the front to the back of the electrode. In addition, the photocatalyst reaction device includes at least one group of unit structures (2). The unit structure (2) has: at least one photocatalyst component (6) and a honeycomb electrode (5), wherein the photocatalyst component (6) ) holds a photocatalyst on its ceramic substrate with a three-dimensional network structure; among a pair of electrodes sandwiching the photocatalyst component 6 between the honeycomb electrode (5), at least one electrode is composed of a conductive shell (4) and It is composed of honeycomb electrode body 3.

Description

technical field [0001] The present invention relates to a photocatalyst reaction device, which can effectively and stably remove harmful substances by using a three-dimensional discharge electrode capable of effectively and stably discharging and the relationship between the discharge light (ultraviolet rays) emitted from the electrode and the photocatalyst. technical background [0002] Dioxins and NO contained in the atmosphere x It is a well-known fact that environmental pollution caused by harmful substances such as pollutants and harmful substances in sewage has become a social problem. Research and development of methods for effectively removing these harmful substances are actively being carried out. In addition, in recent years, ethylene gas as an anti-corrosion gas in refrigerators; formaldehyde, toluene, xylene, and p-dichlorobenzene, which are known as the cause of housing syndrome; Hazardous substances have become a subject for research. [0003] Conventionall...
