Abstract

The invention discloses an organic waste gas purifying device and method. The method comprises the steps that dust particles in waste gas are gathered and separated; high-energy electrons generated by discharge of flowing light and pollution gas molecules collide, and chemical bonds in the molecules are broken and activated; ultraviolet light radiates a nanometer titanium catalyst to generate multiple free radicals and electron holes, and organic waste gas is oxidized and decomposed. By the adoption of needle array positive direct current flowing light discharge, energy density of corona discharge is increased, and more high-energy electrons with high activity can be generated to carry out activating decomposition on the organic waste gas molecules. By means of the synergistic effect of precious metal and the manganese dioxide catalyst, the reaction path is changed, the reaction activation energy is reduced, organic waste gas is promoted to be thoroughly oxidized into dioxide carbon and water, and intermediate products are reduced. Nanometer titanium dioxide generates photos and the electron holes under radiation of ultraviolet light, and then particles with high oxidability of hydroxyl, oxygen free radicals and the like are formed, and subjected to the photochemical oxidation reaction with pollutants.

Description

technical field [0001] The application belongs to the technical field of waste gas treatment, and in particular relates to an organic waste gas purification device and method. Background technique [0002] At present, the main treatment methods of volatile organic compounds at home and abroad include: adsorption method, absorption method, combustion method, plasma and photocatalytic oxidation, etc. Since most VOCs are insoluble in water, the efficiency of absorption method is relatively low, and it is only used as a pretreatment method. The adsorption method has high purification efficiency and can handle multi-component gases. Its disadvantages are that the equipment is huge, the adsorbent is expensive, and it needs to be regenerated or replaced after saturation, and the solid waste generated needs further treatment. The combustion method is suitable for the treatment of combustible gases with high concentration and small gas volume. The purification efficiency is high, an...
