Description

Technical Field

[0001] The utility model relates to a photocatalytic reaction device, in particular to a split-type multifunctional photocatalytic reaction device. Background Art

[0002] Existing photocatalytic reaction devices usually work in the way of directly inserting ultraviolet lamps, that is, placing the ultraviolet lamps in the middle of reaction media such as water bodies, gases, etc. For example, the Chinese patent with the authorization announcement number CN211302631U discloses "an efficient photocatalytic oxidation device", which treats waste gas through multiple ultraviolet lamps installed in the middle of the reactor. This working mode of the reactor has defects. Since the lamps are placed in the reaction medium, only one experiment can be carried out at the same time, which is extremely inconvenient for the situation where multiple experiments are needed to screen the optimal reaction conditions. The Chinese patent with the announcement number CN215694028U discloses "a multi-channel reactor for experiments", which realizes multiple reactions simultaneously by evenly installing multiple single-channel reactor components around a round barrel. It has certain advantages for the situation where multiple experiments are needed to screen the optimal reaction conditions, but for the photocatalytic reaction system, this method has the serious problem of low utilization rate of ultraviolet lamps, directly resulting in the extension of the reaction time.

[0003] In addition, for the situation where multiple experiments are needed to screen the optimal reaction conditions, multiple comparative experiments not only need to be carried out at the same time, but also ensure that there are no significant differences in the reaction environments among the independent reaction channels. For example, it is necessary to ensure that the ultraviolet radiation doses received by each independent reaction channel are the same. Summary of the Utility Model
