Transparent sleeve photothermal reactor

Abstract

The invention discloses a transparent bushing type photo-thermal reactor. The transparent bushing type photo-thermal reactor comprises a box body, a transparent bushing and lamp tubes, wherein the transparent bushing is arranged in the box body; the lamp tubes are positioned at two sides of the transparent bushing and are fixed to the inner wall of the box body; the transparent bushing comprises an outer tube and an inner tube; a top opening is formed in the outer tube, and an air inlet is formed in the side wall of the outer tube; the outer tube is provided with a sealing plug for sealing the top opening in the outer tube; the inner tube is arranged at the inner part of the outer tube and is in threaded connection with the bottom part of the sealing plug; an air outlet which is communicated with the inner tube is formed in the sealing plug; the inner tube is ladder-shaped, and openings are formed in both two ends of the inner tube; the pipe diameter of the bottom part of the inner tube is smaller than that of the top part; a screen is positioned in the inner tube; a silica wool layer I, a catalyst sample and a silica wool layer II are sequentially positioned at the top end of the screen. According to the transparent bushing type photo-thermal reactor disclosed by the invention, the problem of replacement of a catalyst is fully considered; a transparent bushing structure is adopted, so that the sealing performance is good, the disassembly is convenient, the cleaning is convenient, and an application range is wide.

Description

technical field [0001] The invention relates to the technical field of catalyst reaction performance testing, in particular to a transparent casing type photothermal reactor. Background technique [0002] The photothermal reaction process is a combination of light and heat. At a certain reaction temperature, with the assistance of light, the reaction performance of the catalyst is generally much higher than that of a single photocatalytic and thermal catalytic activity. Therefore, to achieve the same reactivity, the temperature of the reaction can be significantly reduced and the selectivity of the reaction can be improved under the participation of light. Conversely, the existence of the heat source can reduce the energy of the required light source, that is, at a certain temperature, the reaction that originally requires a high-energy light source can be performed in the commonly used white light (390-780nm) and ultraviolet light source (254nm). Finish. It is disclosed i...

AI Technical Summary

Problems solved by technology

[0003] There are still many problems in the existing fixed bed reactors, such as less selectivity of the light source, poor sealing effect, no temperature control or low temperature control accuracy, etc. In order to make full use of the light source, the reactor wall is generally made of transparent materials, such as glass quartz, etc. Although the light factor is considered, it is easily affected by external natural light, which will cause errors in the test of catalyst reaction performance and lose the meaning of photothermal reaction test; or use a sealed box to cover, and it is impossible to observe the color change of the catalyst sample in real time

Moreover, the existing photothermal catalytic reactor has a single structure and does not consider the separation and recovery of the catalyst, which makes the replacement of the catalyst very troublesome and inconvenient for experimental operation, which greatly limits its application.
