Description

technical field [0001] The invention relates to the field of photochemical reactions, in particular to a light irradiation multi-sample parallel reaction device. Background technique [0002] With the continuous deepening of research in the field of photochemical reactions, the performance evaluation of different reactants and catalysts under the same light irradiation conditions is particularly important in the experimental research process. Especially in the field of photocatalysis, due to the long time period of photocatalysis experiment, from several hours to several days, if the catalyst is directly used in the experiment, it will take a long time and energy, and at the same time, many other resources such as light source, measurement Instruments, consumables, etc. It takes weeks or even months to complete parallel comparative experiments on the catalytic effects of several sets of samples. [0003] Existing light irradiation parallel reaction devices are generally si...

AI Technical Summary

Problems solved by technology

[0004] (1) It is difficult to guarantee the consistency of smoothness and roundness when the reaction bottle or test tube wall is processed, resulting in poor consistency of the radiation intensity incident into the solution during the parallel comparison experiment, which affects the accuracy of the comparison experiment results

[0005] (2) The utilization rate of light from side incidence is very low

On the one hand, the cylindrical surface of the test tube has high reflectivity and low incident rate of light; on the other hand, the light in the gap of the test tube cannot be used

The existing technology is to strengthen the experimental results by increasing the power of the light source, resulting in a waste of resources

[0006] (3) During the experiment of the reaction device, the test tube rotates around the light source, which increases the difficulty of online sampling and detection, and cannot realize fully automatic operation

[0007] (4) Poor flexibility

Due to the lack of light intensity adjustment system, when choosing different experimental wavelengths, it is necessary to replace the filter, resulting in a significant decrease in luminous flux
