Embodiment 1

[0030] refer to Figures 1 to 3 As shown, the parallel irradiation reaction device of the present invention includes: a support 1, a sample holder 2 and an internal illumination mechanism 3, the internal illumination mechanism 3 includes an internal illumination motor 32 and an internal illumination cylinder 31, and the internal illumination cylinder 31 is a cylinder structure, the inner tube 31 can be rotatably arranged on the support 1 around its axis of rotation, that is, the inner tube 31 can rotate around its own axis of rotation; the inner tube 32 is connected with the inner tube 32, and the inner tube 32 is used To drive the inner cylinder 31 to rotate. The sample holder 2 is arranged on the support 1, and the sample holder 2 is located around the outside of the inner lighting tube 31 for holding the reaction vessel 5; the outer surface of the inner lighting tube 31 is provided with a plurality of light sources 6 for irradiating and placing Reaction vessel 5 on sample ...

Embodiment 2

[0040] This embodiment is basically the same as Embodiment 1, and the same parts as Embodiments 1 and 2 will not be repeated in this embodiment. Multiple light sources are not exactly the same, and more than two kinds of LED lamps, xenon lamps, mercury lamps and halogen lamps are used. For example can have following combination: (1) the light source on the inner lighting tube 31 all adopts LED lamp, and the light source on the outer lighting tube 41 all adopts xenon lamp; (2) the light source on the inner lighting tube 31 adopts LED lamp, xenon lamp And three kinds of mercury lamps; And the light source on the outer lighting tube 41 adopts three kinds of LED lamps, xenon lamps and halogen lamps. The use of different light sources has two advantages: (1) the reaction vessel can be irradiated with light of different wavelengths; (2) different light sources can be lighted for experiments in different reaction stages, without changing the filter, making the light source The selec...

Embodiment 3

[0042] This embodiment is basically the same as Embodiments 1 and 2, and the same parts as Embodiments 1 and 2 will not be repeated in this embodiment. (not shown in the figure), and a filter (not shown in the figure) is arranged between the outer tube 41 and the sample holder 2.

Abstract

The present invention relates to the field of photocatalysis and photochemical reaction, and discloses a parallel irradiation reaction device, comprising a holder, a sample holder and an internal irradiation mechanism, the internal irradiation mechanism comprises an internal irradiation motor and an internal irradiation cylinder, the internal irradiation cylinder can be rotatably arranged on the holder around the rotation axis, the internal irradiation motor and the internal irradiation cylinder are connected for driving the rotation of the internal irradiation cylinder, the sample holder is arranged on the holder, located at the outer side periphery of the internal irradiation cylinder, and used for placing a reaction vessel; and the outer surface of the internal irradiation cylinder is provided with a plurality of light sources for irradiating a sample placed in the reaction vessel on the holder. The internal irradiation cylinder is provided with the plurality of light sources, when in use, the sample holder is stationary, the reaction vessel is uniformly irradiated by the rotation of the internal irradiation cylinder, the reaction vessel is lightened evenly, the sample holder does not move, and online detection can be realized; and by use of the plurality of light sources, even if part of the light sources are aged, other light sources can reduce the effects on test results of light source aging.

Description

technical field [0001] The invention relates to the field of photocatalysis and photochemical reaction, in particular to a parallel irradiation reaction device. Background technique [0002] With the continuous deepening of research in the field of photocatalysis and photochemical reactions, a large number of novel catalysts continue to emerge, and more and more reactions and their parameters need to be investigated and tested. Photocatalysis and photochemical reaction tests under comparable parallel light irradiation conditions are of great importance. Catalyst performance evaluation and reaction parameter screening are particularly important. Compared with the reaction device of non-parallel irradiation, a large amount of experimental resources can be saved. [0003] Existing parallel irradiation reaction devices are generally side-illuminated, mainly including a sample holder and a light source. The sample holder revolves around the axis; the light source is generally s...
