Embodiment Construction

[0055] The purpose and advantages of the present invention can be more fully understood from the following detailed description with reference to the accompanying drawings.

[0056] When a certain intensity of light emitted by the ultraviolet or visible light source 1 irradiates the catalyst 3 supported on the electrode 2, the electrons in the valence band transition to the conduction band, generating electrons and holes, respectively. Strong oxidizing and reducing properties, react with water vapor and oxygen in the air to generate active free radicals, such as OH groups such as OH, H, O 2 - , H, etc., they have a strong ability to react with other substances, break the bonds of organic pollutants to degrade them, and finally generate carbon dioxide and water.

[0057] When the photoelectric catalytic reactor is used for gas fluid, it includes:

[0058] Cathode 4 with reducing properties and anode 5 with oxidizing properties, solid electrolyte 6 separates cathode 4 and anode 5, ...

Abstract

This invention discloses one photoelectric reactor to degrade organic pollute and one method to remove the pollute assistant with catalyze reactor, wherein, the reactor is located with conductive multi-hole materials load compound semi-conductor photo catalyze positive and negative electrodes; the optimized catalyze can be used as light source; it uses conductive solid electrolyte applied to degrade pollute with gas and liquid and to separate metal ions.

Description

Technical field [0001] The invention relates to a photoelectric synergistic catalytic reactor, in particular to a photoelectric catalytic reactor for degrading organic pollutants and a degradation method. Background technique [0002] There are harmful volatile organic compounds such as formaldehyde released from decorative materials in homes, entertainment venues (such as dance halls, etc.), cars, etc., as well as the volatile sweat smell of organisms and harmful microorganisms, bacteria and viruses. These harmful gases not only damage people's physiological functions, but also increase the chance of spreading diseases. Therefore, solving the problem of indoor air pollution is particularly important for people's health. [0003] The currently used scented air purifiers only cover up the unpleasant odor of organic matter, but cannot eliminate their harmfulness. [0004] Another method is adsorption, such as using activated carbon particles to adsorb organic molecules in the gas, ...
