Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a photocatalytic test device for environmental detection. Background Art

[0002] Semiconductor titanium dioxide has been widely used in the photocatalytic degradation of organic pollutants, but it is mainly through the free radical oxidation reaction of hydroxyl radicals produced by the action of light and titanium dioxide with organic pollutants; photocatalytic degradation is the process of using highly active free radicals produced by radiation and photocatalysts in the reaction system, and then degrading pollutants into inorganic substances through processes such as substitution between free radicals and organic pollutants and electron transfer.

[0003] A Chinese patent (publication number CN 215449138 U) discloses a photocatalytic test device for environmental detection, including a test box, a reduction motor is fixedly installed at the bottom of the test box, a vertical axis is fixed on the output shaft of the reduction motor, a test bench is fixedly sleeved on the outer side of the vertical axis, and four test cylinders are fixedly installed on the top of the test bench. The test box of this patent has a good sealing effect. Through the cooperation of the clamping rod, the clamping groove, the reset spring and the slide groove, it is convenient to fix the rotating shaft on the vertical shaft. Through the cooperation of the reduction motor, the vertical axis, the test bench, the test cylinder, the rotating shaft, the incomplete bevel gear, the driven bevel gear, the horizontal axis, the torsion spring, and the lamp tube, the photocatalyst in each test cylinder can be evenly illuminated to avoid uneven illumination of the photocatalyst, which affects the accuracy of the test results.

[0004] When the above scheme is implemented, as water is introduced into the interior of the test box through the water outlet pipe and the cold water pipe, the interior of the test box except the interior of the test tube will be filled with water. On the one hand, a large amount of water resources will be consumed in the process of continuously cooling down and introducing cold water. On the other hand, the water level in the test box needs to be observed at any time. If the water level is too high, the water will flow back into the test tube, causing the reaction in the test tube to fail, which is a great hidden danger. Utility Model Content
