Aeration, stirring and temperature control are integrated by aerating in solution and adjusting the temperature of gas used by aeration, so that precise and quick temperature control is realized, a stirring effect is achieved, the overall uniformity of the solution is realized, the photochemical reaction module is simplified, and the cost is reduced; meanwhile, the illumination wavelength can also be controlled, a plurality of experiments can be simultaneously performed at one time, and the experiment efficiency and the comparability of an experiment result are improved.

Description

technical field [0001] The invention relates to an experimental device, in particular to a research device for photochemical conversion of environmental pollutants integrated with temperature control, aeration and stirring. Background technique [0002] Photochemical degradation is an important transformation process of pollutants in the water environment, and the study of the mechanism of pollutant photochemical degradation is the basis for clarifying the environmental fate of pollutants and evaluating the environmental risk of pollutants. However, there are many factors affecting the degradation of pollutants in water bodies, such as temperature, oxygen content, light wavelength and other parameters will directly affect the pathways, products and mechanisms of the photochemical degradation of pollutants. It is difficult to strictly control the above influencing factors by using the existing photochemical photochemical reaction module, which directly affects the accuracy an...

AI Technical Summary

Problems solved by technology

[0003] (1) The relatively simple device cannot be tested in parallel, and only a single influencing factor can be considered, resulting in poor accuracy and precision of the experimental results (such as patent 201320130115.3)

[0004] (2) Although the more complex design can comprehensively consider the conditions of stirring, filtering and aeration, the temperature conditions are not considered (such as patents 200720196142.5, 201010293017.2, 201410361142.0)

Long-term irradiation of the sample by a high-power light source will cause the temperature of the reaction system to rise, which will affect the accuracy of the experimental results

[0005] (3) The realization of stirring mostly adopts electromagnetic stirring or motor stirring, which increases the complexity of the device and increases the cost;

[0006] (4) The modularity of the overall design is poor, which causes the overall design to be too complicated when multiple factors are considered comprehensively, which increases the cost and affects the expansion of the photochemical reaction device function;
