Photocatalytic water treatment reactor

Abstract

The invention relates to a device used for sewage treatment, in particular to a photocatalytic water treatment reactor designed for the optical catalyst of two-dimensional nano-optical catalytic film loaded by a substrate, particularly to a visible light catalytic film developed in recent years. The reactor comprises a reaction container, an ultraviolet lamp (or xenon lamp), a catalyst carrier installation device, a mixing device and an air aerating device. The reactor is characterized in that the middle part of the lower end surface of the cover plate of the reaction container is fixedly connected with a lampshade; the catalyst carrier installation device is a polyhedron slot frame; the glass sheet of a supported catalyst film is arranged on the polyhedron slot frame from top to bottom; the upper end of the mixing shaft of the mixing device passes through the mixing shaft hole on the soleplate of the reaction container and is arranged in the reaction chamber of the reaction container; and the polyhedron soleplate of the polyhedron slot frame is fixedly connected with the upper end of the mixing shaft. The device has the advantages of simple structure and convenient installation and replacement of the optical catalytic film and simultaneously can carry out the optical catalytic reaction of the variable light source by an artificial light source or solar light under the condition of ultraviolet light or visible light and natural light.

Description

Technical field [0001] The invention relates to a device for sewage treatment. Background technique [0002] The research and design of photocatalytic reactors is one of the focal issues that need to be solved in the practical process of photocatalytic oxidation. The first heterogeneous photocatalytic reactor was designed for research in the laboratory. Its structure is very simple and its operation is very convenient. The main body of the reactor is generally a container with an open opening and is placed on a magnetic stirrer. The reaction liquid reacts under the irradiation of a fluorescent or ultraviolet lamp, and the distance between the lamp and the liquid surface is adjustable. Until now, there are still many researchers using this type of reactor to evaluate the activity of the catalyst or to study the degradation of pollutants.

Problems solved by technology

[0003] Since the use of photocatalytic reactors to degrade refractory organic compounds through photocatalytic oxidation reactions under ultraviolet light, many researchers have devoted themselves to the study of such advanced chemical oxidation technologies, but there are few large-scale industrial applications. The problem is the lack of suitable high-efficiency photocatalytic reactors
