However, the recycling of small-sized semiconductor materials must be considered in an open system, because unrecycled small-sized semiconductor materials may be more harmful to the environment, especially nanopowder materials
In addition, when photocatalytic oxidation technology treats large-flow industrial waste gas, due to the short residence time of organic waste gas in traditional photocatalytic oxidation equipment, semiconductor photocatalysts cannot effectively and completely oxidize and degrade organic pollutants at one time.

Abstract
The invention discloses a composite photocatalytic oxidation reaction device for treatment of industrial waste gas. The device includes gas-solid phase photocatalytic reaction equipment and liquid-solid phase photocatalytic reaction equipment. Specifically, the gas-solid phase photocatalytic reaction equipment comprises an outer shell, a "spring-shaped" pipeline, a loaded type semiconductor photocatalytic material and light sources, the loaded type semiconductor photocatalytic material is filled in the "spring-shaped" pipeline, and the "spring-shaped" pipeline and the light sources are arranged in the outer shell; the liquid-solid phase photocatalytic reaction equipment comprises a container, light sources, liquid, a powder semiconductor photocatalytic material and a gas distributor, wherein the light source and the liquid are arranged in the container, the gas distributor is arranged at the bottom of the container, the powder semiconductor photocatalytic material is dispersed in theliquid, and the "spring-shaped" pipeline is connected to the gas distributor via the bottom of the outer shell through a glass pipeline. The composite photocatalytic oxidation reaction device has an excellent degradation effect.
Description
technical field [0001] The invention relates to a photocatalytic oxidation reaction, in particular to a composite photocatalytic oxidation reaction device for treating industrial waste gas. Background technique [0002] The rapid economic development has brought serious environmental problems to human beings, especially the atmospheric environment on which human beings depend has been seriously polluted. The large discharge of volatile organic compounds (volatile organic compounds, VOCs) is the chief culprit of atmospheric environmental pollution. These compounds not only destroy the atmospheric environment, but also pollute the water environment and soil environment. As we all know, the vast majority of volatile organic compounds are toxic, and even some compounds can induce diseases and have "three-cause" effects (carcinogenic, teratogenic, and mutagenic). Therefore, volatile organic compounds have seriously threatened the living environment of human beings. Effectively c...
