DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] like Figure 1-2 As shown, a UV glass pipe reaction system includes a material tank 1, a material pump 2, and a UV irradiation pipe 3, wherein the electric control valve 16 and the PLC controller shown in the figure are default settings in this embodiment, and the UV irradiation pipe 3 is a single pipe. The UV irradiation pipe 3 includes an outer pipe 4, an inner pipe 5 and a UV lamp 6, wherein the inner pipe 5 is a glass pipe, and the UV lamp 6 is arranged in the inner pipe 5. One end of the inner pipe 5 and the outer pipe 4 are both open ends, and the other end is a closed end, and the inner pipe 5 and the outer pipe 4 are connected by a conical fixing seat to ensure the smooth flow of the gap between the inner glass tube and the outer glass tube, i.e., the jacket 7; the feed port and the discharge port are respectively opened on both sides of the outer pipe 4.

[0028] The outer pipe 4 is sleeved on the inner pipe 5, and a jacket 7 for material circulation is formed between the inner pipe 5 and the outer pipe 4. The open ends of the inner pipe 5 and the outer pipe 4 are sealed and connected by a first flange fastening device. A feed port and a discharge port are respectively opened on both sides of the outer pipe 4. The feed port is connected to the material pump 2 through a pipeline, the material pump 2 is connected to the material tank 1 through a pipeline, and the discharge port is connected to the material tank 1 through a pipeline.

[0029] In this embodiment, the first flange fastening device includes a first flange 9, a second flange 8 and a first sealing gasket 10. The open end of the outer pipe 4 is provided with a clamping ring 11. The first flange 9 is sleeved on the outer pipe 4 and limited by the clamping ring 11. The second flange 8 is sleeved on the inner pipe 5. The first sealing gasket 10 is sleeved on the inner pipe 5. One end of the first sealing gasket 10 abuts against the clamping ring 11 of the outer pipe 4. The first flange 9 and the second flange 8 are fastened by bolts.

[0030] When the reaction system of this embodiment is running, when the feed liquid flows in the jacket 7 through the suction of the material pump 2, it will squeeze the first sealing gasket 10, and the first sealing gasket 10 will squeeze the second flange 8. However, the first flange 9 and the second flange 8 are fastened together by bolts, and the first flange 9 is limited by the clamping ring 11 at the end of the outer pipe 4. Therefore, even under the action of pressure, no displacement will occur, and a self-locking structure is formed to ensure that the sealing surfaces of the inner pipe 5 and the outer pipe 4 will not leak, increase the pressure bearing capacity of the equipment, increase the circulation flow rate, and reduce the reaction time. The system can withstand a pressure of up to 0.15MPa and a reaction capacity of up to 1200L / h.

[0031] Example 2

[0032] like Figure 1-2 As shown, the ultraviolet glass pipe reaction system provided in this embodiment is not described in detail in the same parts as those in Embodiment 1, except that the first sealing gasket 10 is conical, the bottom of the second flange 8 is provided with a second conical surface matched with the first conical surface of the first sealing gasket 10, and the first conical surface of the first sealing gasket 10 abuts against the second conical surface of the second flange 8. Through the cooperation between the first conical surface and the second conical surface, the first sealing gasket 10 can be well sealed and fixed between the end of the outer pipe 4 and the second flange 8.

[0033] At the same time, a first groove 12 is provided on the end surface of the collar 11 facing the first sealing gasket 10. The function of the first groove 12 is that when the first sealing gasket 10 is fixed between the collar 11 and the first flange 9, the first sealing gasket 10 is squeezed so that a part of its end surface close to the collar 11 is embedded in the first groove 12, so as to limit the first sealing gasket 10 and prevent the first sealing gasket 10 from radially deviating.

[0034] This embodiment further increases the sealing effect, circulation flow rate, and pressure bearing capacity of the reaction system, avoiding the possibility of sealing surface leakage caused by various angles and pressure changes; the system can withstand a pressure of up to 0.18MPa and the reaction capacity can reach 1600L / h.

[0035] Example 3

[0036] like Figure 1As shown, in this embodiment, based on the reaction system of embodiment 2, the ultraviolet irradiation pipeline 3 is increased to multiple, and the multiple ultraviolet irradiation pipelines 3 are connected in sequence to form a continuous U-shaped arrangement. The feed inlet and the discharge outlet of the ultraviolet irradiation pipeline 3 are respectively arranged at both ends; the feed inlet and the discharge outlet of the adjacent ultraviolet irradiation pipelines 3 are sealed and connected by a second flange fastening device.

[0037] like Figure 3 As shown, in this embodiment, the second flange fastening device includes a second flange 14 and a second annular sealing gasket 15, and the second sealing gasket 15 is respectively installed on the end faces of the feed port and the discharge port of the adjacent ultraviolet irradiation pipeline 3, and the second flange 14 fastens and seals the feed port and the discharge port of the adjacent ultraviolet irradiation pipeline 3 provided with the second sealing gasket 15. Second grooves 13 are respectively provided on the end faces of the feed port and the discharge port of the adjacent ultraviolet irradiation pipeline 3. In this embodiment, a long straight pipeline in the prior art is set as a continuous U-shaped pipeline, so that the feed liquid passes through the same length of the material pipeline, and the volume occupied by the material pipeline is smaller, and the role of the second groove 13 is that when the second sealing gasket 15 is tightly docked under the action of the second flange 14, the second sealing gasket 15 is squeezed so that its end face close to the feed port and the discharge port will be partially embedded in the second concave, and the second sealing gasket 15 is limited to avoid radial displacement of the second sealing gasket 15, so that the sealing effect is better.

[0038] This embodiment enhances the photoreaction effect and improves the reaction efficiency by increasing the photoreaction path, and the reaction time can be shortened to 1 / 3 of the conventional system; at the same time, the pressure resistance and circulation flow rate are further increased. The system can withstand a maximum pressure of 0.2MPa and a reaction capacity of 1800 / h.

[0039] In some preferred embodiments, the first sealing gasket 10 and the second sealing gasket 15 in Example 3 are both made of PTFE wrapped in EPDM rubber, the inner pipe 5 is a glass pipe or a pressure-resistant quartz pipe, and the outer pipe 4 is a pressure-resistant quartz pipe or other pressure-resistant and corrosion-resistant pipes made of non-glass materials.

[0040] Example 4

[0041] like Figure 1-3 As shown, this embodiment adds a pressure interlock device on the basis of the reaction system of Example 3, and the material pump 2 is a variable power material pump. The pressure interlock device is composed of an electric control valve 16, a PLC controller, and a pressure gauge. One end of the electric control valve 16 is connected to the pipeline between the material tank 1 and the discharge port through a pipeline, and the other end is connected to the pipeline between the material pump 2 and the feed port through a pipeline; the PLC controller is connected to the press, the electric control valve 16, and the material pump 2.

[0042] This embodiment maintains the pressure stability of the reaction system by adding a pressure interlock device. When the system pressure value exceeds the maximum tolerable value, the PLC controller controls the electric control valve 16 to open, diverts and reduces the pressure, and reduces the operating power of the material pump 2 at the same time, so that the system operates within the tolerable pressure range, avoids system damage and personnel injury caused by pressure overload, and can cope with a variety of reaction scenarios; when the system pressure value is lower than the normal operating pressure, the PLC controller increases the operating power of the material pump 2 while keeping the electric control valve 16 closed, increases the material circulation flow, and ensures that the reaction efficiency is fully utilized.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
