Description

technical field [0001] The invention relates to experimental equipment, and more particularly to a photocatalytic magnetic suspension stirring device and a refrigerated reaction box using the device. Background technique [0002] The photocatalytic reaction means that the reaction system containing the catalyst excites the reaction molecules under the irradiation of light or stimulates the catalyst to form a complex with the reaction molecules, converts the light energy into chemical energy, and promotes the reaction process. [0003] In the prior art, the magnetic levitation photocatalytic stirring is mostly driven by the bottom of the magneton, and the magneton easily blocks the illumination area of ​​the light source, which affects the photocatalytic rate and experimental results. Most of the refrigerated reaction boxes above are easy to cause the reaction temperature to be higher than the required reaction temperature due to the self-heating of the light source during op...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, most of the magnetic levitation photocatalytic stirring is driven by magnetons at the bottom, which can easily block the illuminated area of ​​the light source, affect the photocatalytic rate and experimental results, and easily lead to poor stability of the magnetic field, thereby affecting the stirring effect. Due to the self-heating of the light source, most of the refrigeration-type reaction boxes in the world tend to cause the reaction temperature to be higher than the required reaction temperature, and cannot maintain the system environment of 5°C-room temperature, so that the reaction conditions are unqualified and affect photocatalysis.

[0004] Chinese patent application CN201210134726.5 discloses a photocatalytic reaction treatment device, the application includes a box, a light source, a photocatalytic reactor, a lifting platform, a magnetic stirrer, a magnet and an electrical system, through the center of the photocatalytic reactor top plate There is a sunken circular light source cylinder matching the tubular light source. A magnet is placed on the bottom plate of the cylinder. The magnet is wrapped with cloth or gauze and is provided with a cloth or gauze thread at both ends. The magnet is placed on the magnetic stirrer. Under the action, the air in the reactor is stirred to imitate the polluted gas, so that it can fully contact and mix with the photocatalyst, so as to improve the photocatalytic rate of the experiment. The difference between this application and this application is that the magnetron is driven at the bottom, which is easy to block the illuminated area of ​​the light source , affecting the photocatalytic rate and experimental results

[0005] Chinese patent application CN202120006222.X discloses an auxiliary device for photocatalytic reaction. The rotor, fixed sealing sleeve and other structures realize the uniform irradiation of the reaction device without dead angle, providing a stable light source for the reaction device, and the arrangement of the electronic refrigeration sheet in the interlayer of the box can effectively reduce the temperature in the box. This application uses a refrigeration sheet To cool down the box, but the refrigeration technology is immature, the energy consumption is high, the application is not wide, and it cannot be recycled
