A rotary barrel photocatalytic reaction device

Abstract

The invention discloses a rotary drum type photo-catalytic reaction device. A metal reactor bracket is connected with an outer cylinder barrel; the outer cylinder barrel is supported by the metal reactor bracket; a certain included angle is formed between the outer cylinder barrel and the ground; an inner cylinder barrel is placed in the outer cylinder barrel; three uniform annular permanent magnets are mounted on the outer wall of the inner cylinder barrel and are matched with the outer cylinder barrel; a light source is inserted into the center of the outer cylinder barrel and is not in contact with the outer cylinder barrel; a shoveling plate is mounted on the inner wall of the inner cylinder barrel and is parallel to the light source; an annular permanent magnet is parallel to the three uniform annular permanent magnets and is mounted outside the outer cylinder barrel; the shoveling plate and the inner cylinder barrel rotate together, so that a catalyst can be updated; a sealing metal flange is mounted at the top of the outer cylinder barrel; a gas inlet and a gas outlet are symmetrically formed in the sealing metal flange and cannot rotate along with the inner cylinder barrel; screws are arranged at two ends of the sealing metal flange. The surface of the catalyst can be updated, and the problem of sealing caused by mechanical stirring is solved.

Description

technical field [0001] The invention relates to a photocatalytic experimental reaction device, which belongs to the field of photocatalytic instruments and devices. Background technique [0002] Since the discovery of photocatalyst by Professor Fujishima Akira of the University of Tokyo in 1967, photocatalysis has been gradually proposed. In 1972, Fujishi and others published "Electrochemical photolysis of water at semiconductor electrode" on Nature, which opened the prelude to a new era of photocatalysis. In the following decades, photocatalysis technology has received widespread attention. Photocatalysis is a substance that does not change itself under the irradiation of light, but can promote chemical reactions. In recent years, with the lack of energy and the aggravation of environmental pollution, the photocatalytic field is also constantly improving the requirements, so it is imperative to improve the utilization rate of the photocatalytic equipment for the catalyst. ...
