Description

Technical Field

[0001] The utility model relates to the field of photo-oxidation reaction, in particular to a double falling film internal light source photo-oxidation reaction device. Background Art

[0002] Photooxidation reaction is the reaction of materials with oxygen under the action of light. Current photooxidation reaction devices all include container-type reactors. A light source is arranged at the center of the reactor, oxygen is contained in the reactor, and then the materials are put into the reactor for photooxidation reaction. Such photooxidation reaction devices have certain defects, such as short contact time between materials and oxygen, small effective contact area, and relatively low reaction efficiency. Therefore, it is urgent to design a photooxidation reaction device that can achieve full contact between materials and oxygen. Utility Model Content

[0003] The utility model aims to provide a double falling film inner light source photo-oxidation reaction device. Through the design of a light-transmitting glass tube and the film-distributing nozzles on both sides of the glass tube, the material input into the photoreactor through a pump is evenly distributed on the inner and outer walls of the glass tube to form a film, so that the material on the inner and outer walls of the light-transmitting glass tube can be in good contact with the oxygen / air and light in the inner cavity of the photoreactor, thereby promoting the photo-oxidation reaction and improving the photo-reaction efficiency.

[0004] In order to achieve the above objectives, the technical solution adopted by the utility model is: a double falling film internal light source photo-oxidation reaction device, including a reactor and a base, a light source is arranged at the center of the reactor, a mounting frame is arranged at the bottom of the reactor, a light-transmitting glass tube is arranged on the mounting frame, and film-distributing nozzles are arranged on both sides of the light-transmitting glass tube in the reactor.

[0005] Preferably, at least two layers of light-transmitting glass tubes are arranged on the mounting frame, and all the light-transmitting glass tubes are centered on the light source, and film-spreading nozzles are arranged inside and outside the light-transmitting glass tubes.

[0006] Preferably, a circulation pump is arranged on the base, the circulation pump is connected with the bottom of the reactor, and the circulation pump is connected with the film spreading nozzle through a circulation pipe.

[0007] Preferably, leakage holes are provided at the center of the mounting frame and in the area between adjacent light-transmitting glass tubes.

[0008] Preferably, the film-making nozzles in the reactor are distributed in a ring shape with the light source as the center, and the film-making nozzles in the same radial direction are connected to the same nozzle connecting pipe, and the other end of the nozzle connecting pipe passes through the reactor and is connected to the circulation pump through the circulation pipe.

[0009] Preferably, an oxygen supply interface is installed on the upper cover of the reactor, and the oxygen supply interface is connected to an oxygen supply pipeline structure.

[0010] Preferably, a material input interface is installed on the upper cover of the reactor, and the material input interface is matched with a sealing cover.

[0011] Preferably, the outer side of the reactor is sleeved with a temperature raising and lowering jacket for adjusting the temperature of the material in the reactor.

[0012] The technical effects of the utility model are:

[0013] Through the design of the light-transmitting glass tube and the film-dispensing nozzles on both sides of the glass tube, the materials on both sides of the light-transmitting glass tube can be in good contact with the oxygen / air in the inner cavity of the photoreactor, thereby promoting the photooxidation reaction and improving the reaction efficiency.

[0014] The design of multi-layer light-transmitting glass tubes can further increase the full contact between the material and the oxygen in the reactor.

[0015] The design of the circulation pump and circulation pipe can cooperate with the film-making nozzle to circulate the materials and make the films on the inner and outer walls, ensuring that all materials can complete the photo-oxidation reaction.

[0016] The design of the mounting frame and the leakage hole can realize the installation of multi-layer light-transmitting glass tubes without affecting the circulation of materials.

[0017] Connecting the film-distributing nozzles in the same radial direction to the same nozzle connecting pipe can simplify the circulation pipeline structure.

[0018] The design of the oxygen supply interface and the material input interface together with the sealing cover can replenish oxygen during the cyclic reaction process.

[0019] The design of the temperature raising and lowering jacket can adjust the temperature of the material to ensure that the material forming the film in the photoreactor has a suitable reaction temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0024] Example 1

[0025] like Figure 1-2 As shown, the specific structure of the utility model is: a double falling film 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, and is characterized in that a mounting frame 12 is arranged at the bottom of the reactor 1, and no less than two layers of light-transmitting glass tubes 13 are arranged on the mounting frame 12, and all the light-transmitting glass tubes 13 are centered on the light source 3, and film-making nozzles 6 are arranged on both sides of the light-transmitting glass tubes 13 in the reactor 1, a circulation pump 4 is arranged on the base 2, and the circulation pump 4 is connected to the bottom of the reactor 1, and the circulation pump 4 is connected to the film-making nozzle 6 through the circulation pipe 5, and a leakage hole 14 is arranged at the center of the mounting frame 12 and in the area between adjacent light-transmitting glass tubes 13.

[0026] 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 between 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 film-making nozzle through the circulation pump 4 and the circulation pipe 5, and then the material is uniformly filmed on the inner and outer walls of the glass tube through the film-making nozzle, so that the material can be in contact with oxygen in the form of a thin film, and sufficient contact between the gas and liquid film can be achieved, thereby increasing the reaction speed, and the materials that have completed the photo-oxidation reaction and the materials that have not completed the photo-oxidation reaction will fall to the bottom of the reactor, and the leakage port 14 on the mounting frame 12 can ensure that the material can enter the bottom of the reactor, and cooperate with the function of the circulation pump to form a double falling film on the inner and outer walls for continuous circulation, and to carry out a cyclic photo-oxidation reaction, thereby ensuring that the photo-oxidation reaction of the material is complete.

[0027] Example 2

[0028] Compared with Example 1, in this embodiment, the film-making nozzles 6 in the reactor 1 are distributed in a ring shape with the light source 3 as the center, and the film-making nozzles 6 in the same radial direction are connected to the same nozzle connecting tube 7. The other end of the nozzle connecting tube 7 passes through the reactor 1 and is connected to the circulation pump 4 through the circulation pipe 5.

[0029] Compared with Example 1, in this embodiment, the film-making nozzles 6 are distributed in a ring shape with the light source as the center, and all the film-making nozzles 6 in the same radial direction are circulated and fed through the nozzle connecting pipe 7. Compared with each film-making nozzle being connected to a circulation pipe 5, the structure of the entire circulation pipeline can be simplified.

[0030] Example 3

[0031] Compared with Example 1, the upper cover of the reactor 1 of this embodiment is equipped with an oxygen supply interface 11, and the oxygen supply interface 11 is connected to the oxygen supply pipeline structure. The upper cover of the reactor is equipped with a material input interface 9, and the material input interface 9 is equipped 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 inner and outer wall film photooxidation reaction is consistent with Example 1.

[0033] Example 4

[0034] Compared with Example 1, the reactor 1 of this embodiment is sleeved with a temperature increasing and decreasing jacket 8 for adjusting the temperature of the material in the reactor.

[0035] During the photo-oxidation reaction, a certain reaction temperature is sometimes required. In this way, 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 cyclic film formation, it is ensured that the film-forming material reaches the temperature required for the reaction.
