[0021] Example 1

[0022] like Figure 1-2As shown, the specific structure of the utility model is: a circulating atomizing internal light source photo-oxidation reaction device, comprising a reactor 1 and a base 2, a light source 3 is arranged at the center of the reactor 1, characterized in that a circulating pump 4 is arranged on the base 2, the circulating pump 4 is connected to the bottom of the reactor 1, and atomizing nozzle groups are distributed in a ring shape in the reactor 1, each atomizing nozzle group is composed of at least two atomizing nozzles 6 of different heights, the atomizing nozzle 6 is connected to the circulating pump 4 through a circulating pipe 5, and the atomizing nozzle outlet specification is 1-4mm, and the flow rate is 30-200L / h.

[0023] The specific operation of this embodiment is as follows: the material to be reacted is put into the reactor 1, and then oxygen is introduced into the reactor 1, and then the light source is started to promote the photo-oxidation reaction of the material and oxygen under the action of light, and then the circulation pump 4 (the pump is equipped with a driving motor) is operated to send the material at the bottom of the reactor 1 to the atomizing nozzle 6 through the circulation pump 4 and the circulation pipe 5, and then the material is sprayed in the form of a spray onto the inner and outer sides of each light-transmitting glass tube through the atomizing nozzle, so that the material can be in contact with oxygen in an atomized state, achieving sufficient contact of gas-liquid atomization, improving the reaction speed, and being able to circulate and atomize the material in the reactor to ensure that the photo-oxidation reaction of the material is complete.

[0024] Example 2

[0026] Compared with Example 1, in this embodiment, each atomizing nozzle group supplies multiple atomizing nozzles through a nozzle connecting pipe 7. Compared with each atomizing nozzle being connected to a circulation pipe 5, the structure of the entire circulation pipeline can be simplified.

[0027] Example 3

[0028] Compared with Example 1, in this embodiment, a temperature increasing and decreasing jacket 8 for adjusting the temperature of the material in the reactor is sleeved on the outer side of the reactor 1 .

[0029] During the photo-oxidation reaction, a certain reaction temperature is sometimes required. In this case, the temperature of the material deposited at the bottom of the reactor 1 can be adjusted by raising and lowering the temperature jacket 8, and then after the circulating spraying, the atomized material can be ensured to reach the temperature required for the reaction.

[0030] Example 4

[0031] Compared with Example 1, the upper cover of the reactor 1 of this embodiment is provided with an oxygen supply interface 11, and the oxygen supply interface 11 is connected to an oxygen supply pipeline structure. The upper cover of the reactor 1 is provided with a material input interface 9, and the material input interface 9 is matched with a sealing cover 10.

[0032] Compared with Example 1, when feeding, this embodiment first opens the sealing cover 10, and then connects the material input interface 9 with the material conveying structure (the material can also be poured into the material input interface by manually holding a container), and the material is put into the reactor from the material input interface 9 through the material conveying structure, and then the material input interface 9 is closed through the sealing cover 10, and the oxygen delivery pipeline is connected to the oxygen supply interface 11. When it is used specifically, a pressure meter can also be set in the reactor, and the oxygen supply pipeline structure connected to the oxygen supply interface 11 can be used to maintain the pressure in the photoreactor at 1-1.1 bar. The subsequent cyclic spray photooxidation reaction is consistent with Example 1.
