[0026] In some embodiments, the photocatalytic reactor further comprises a light source module arranged at the outer periphery of the reaction chamber 3 and fixedly connected with the reaction chamber 3, and the light source module can provide light for the reaction chamber 3.

[0027] In some embodiments, the light source module comprises a plurality of light units 9, each light unit 9 comprises a lamp strip and an outer tube, each outer tube surrounds the outer periphery of the reaction chamber 3 at equal distances and is fixedly connected with the reaction chamber 3, and the lamp strip is connected to the outer tube and faces one side of the reaction chamber 3, the lamp strip can emit light towards one side of the reaction chamber 3, and the outer tube is used to circulate cooling medium to cool the lamp strip. A plurality of lamp strips surround the outer periphery of the reaction chamber 3 at equal distances, which can provide light to the reaction chamber 3 from different angles, reduce the light dead angle, and ensure that the photocatalyst at each position in the reaction chamber 3 can receive relatively uniform light, so that the photocatalytic reaction can be more uniformly carried out in the entire reaction space, which is conducive to improving the consistency of the reaction and the quality stability of the product, and the outer tube can conduct the heat generated by the lamp strip away, maintain the temperature of the lamp strip within a reasonable range, protect the performance of the lamp strip, and stabilize the light emission, so as to maintain a relatively stable temperature environment in the reactor, keep the photocatalyst at a relatively optimal working temperature, and ensure the efficient photocatalytic reaction.

The liquid inlet 8 and the gas inlet 7 are arranged separately, which facilitates independent adjustment of the liquid and gas feed amounts, more accurate control of the gas-liquid ratio, and achievement of optimal reaction conditions, thereby improving the conversion rate of the reaction and the quality of the product.

[0031] In some embodiments, the photocatalytic reactor further includes a plurality of temperature measuring devices 6, which are arranged in the upper, middle and lower parts of the reaction chamber 3 and can contact the liquid in the reaction chamber 3 to measure the liquid temperature in the reaction chamber 3.

[0032] In some embodiments, the materials of the reaction chamber 3 and the inner tube 5 are both quartz materials.

[0033] In some embodiments, the gas inlet pipe extends into the inner cavity of the reaction chamber 3 through the gas inlet 7, and the extension direction of the gas inlet pipe is along the tangential direction of the reaction chamber and perpendicular to the axis direction of the reaction chamber.

At the same time, the rotational flow is also helpful for more uniform distribution of the gas in the reaction chamber 3, avoiding local gas concentration being too high or too low, and making the reaction proceed more uniformly in the whole reaction chamber 3.
