Description

TECHNICAL FIELD

[0001] The utility model relates to light reaction device technical field especially is related to a continuous flow light reaction device. BACKGROUND

[0002] In the Chinese patent with publication number CN207887147U, a spiral coil pipe type tubular photocatalytic reaction device is disclosed, which is provided with multiple light sources between the cylindrical reflector and the spiral coil pipe type reactor, and the cylindrical reflector and the spiral coil pipe type reactor are coaxially placed for light reflection. However, the device does not have a material temperature control structure, and cannot control the temperature of the reaction material. In addition, the device adopts a design of multiple light sources in the outer ring of the ultraviolet lamp, which increases the design cost compared with the design of a single light source in the inner irradiation type, and the utilization rate of the reaction light source is too low. In addition, the reaction light source does not have a light source heat dissipation system, which makes it unable to be compatible with higher power UV light sources and other visible light high power light sources.

[0003] In the Chinese patent with publication number CN207680585U, a vitamin D2 light reaction device with improved reaction efficiency is disclosed. In the device, the light reaction tube, the ultraviolet light emitting device, and the light reflector are coaxially fixed in a closed light-tight box. The light reaction tube adopts an inner and outer double-layer spiral coil quartz tube. The ultraviolet light emitting device irradiates the reaction disc tube on a single side at the top of the box, and then the light reflector at the bottom of the box reflects the light source for light reaction. The outer coil of the light reaction disc tube is connected to the reaction liquid, and the inner coil is connected to the cooling water. Compared with the liquid bath type temperature control structure, the heat exchange area of this temperature control structure is small, and the special irradiation position at the top of the plane will cause the direct irradiation area of the light reaction tube to be too small, and the light source utilization rate is too low. In addition, the reactor light source structure is special and does not have a light source temperature control, which cannot be compatible with the columnar light emitting light source.

[0004] The applicant found that the existing technology has the following technical problems: for the existing tubular light reaction device, the reaction disc tube used in the device is usually in a planar coiled or single-layer axial spiral coiled manner. At the same time, most of the light sources of the reaction device are in a planar irradiation manner, which irradiates the reactor disc tube on one side or both sides through the planar light source. The above setting mode has the problems of limited light irradiation area of the reaction disc tube and low reaction efficiency. In addition, most of the reaction light sources do not have a light source heat dissipation system, which makes it unable to be compatible with higher power columnar light emitting light sources, and the light source utilization rate is too low.
