Abstract

The invention discloses an ultraviolet photo-catalytic oxidation device which comprises a reactor. One end or two ends of the reactor are connected to reflective hoods, an ultraviolet reflective coating is arranged on the inner surface of each of the reflective hoods, the reflective hood is connected to a first ultraviolet lamp, a photo-catalytic oxidation layer is connected to the inner wall of the reactor, an air inlet is formed in any side, connected to the reflective hood, of the reactor, an air outlet is formed on the other side of the reactor, and the photo-catalytic oxidation layer is located between the air inlet and the air outlet. The ultraviolet photo-catalytic oxidation device disclosed by the invention can reduce the quantity of the used ultraviolet lamps, so that the cost is greatly lowered, and meanwhile, the irradiating effect of the ultraviolet lamps enhances the ultraviolet photo-catalytic effect.

Description

technical field [0001] The invention specifically relates to an ultraviolet photocatalytic oxidation device, which belongs to the field of photocatalytic equipment. Background technique [0002] VOC is the English abbreviation of volatile organic compounds, which can cause harm to human health. The current technology for degrading VOC includes photocatalytic oxidation. VOC photocatalytic oxidation usually refers to the gradual oxidation of organic waste gas VOC into low-molecular intermediate products and finally CO 2 、H 2 O and other ions such as NO 3 - 、PO 4 3- , Cl - Waiting process. But so far, the ultraviolet photocatalytic devices on the market generally need to use multiple ultraviolet lamps at the same time and the ultraviolet light emitted by the ultraviolet lamps is scattered, which in turn will cause the problems of low ultraviolet photocatalytic efficiency and high equipment cost. Contents of the invention [0003] The technical problem to be solved by ...
