Description

Technical Field

[0001] The present invention relates to the technical field of chemical experimental equipment, and in particular to a device for photocatalytic degradation of organic dyes for teaching. Background Art

[0002] The existing teaching-use photocatalytic degradation of organic dyes device is equipped with eight reaction sites, and the light intensity received by each reaction site is consistent. It can carry out 8 parallel experiments at the same time, but the existing teaching-use photocatalytic degradation of organic dyes device has a low utilization rate of light. The following problems were found during the student experiment: First, because the box is black, it will absorb part of the light, resulting in a reduction in the light irradiated on the photocatalyst, and the experiment has a low utilization rate of light; second, because the device contains a condenser cooling system and a floor-standing iron stand, the space occupancy rate is large, which makes it very inconvenient for students to take samples, and there is even a risk of damaging the reaction vessel. In fact, only 6 reaction sites can be used, and the two innermost reaction sites of the device cannot be used due to crowded space, which greatly reduces the utilization rate of the reaction sites.
