[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figure 1-3 This utility model provides an embodiment of a cascade reaction device for the synthesis of methyltetrahydrofolate from carbon dioxide under photocatalytic conditions. The device includes a base 1, with four support frames 14 arranged side-by-side from left to right. Within each support frame 14, from left to right, are arranged a catalytic tank 9, a biosynthesis tank 5, a non-polar column filter tank 3, and a collection tank 2. This constitutes a complete process for the production of methyltetrahydrofolate. A gas supply pipe 17 is installed at the bottom of the catalytic tank 9 to supply carbon dioxide. A transparent cover 16 is vertically installed in the middle of the catalytic tank 9, and an aurora column 20 is arranged inside the transparent cover 16, with the aurora column 20 having a uniform surface... The biosynthesis tank 5 is equipped with evenly distributed LED light-emitting chips. The light catalyzes the reaction of carbon dioxide and water to produce methyltetrahydrofolate. A stirring shaft 19 is rotatably connected inside the biosynthesis tank 5 to promote the synthesis of methyltetrahydrofolate. A feed pipe 6 is provided at the top of the biosynthesis tank 5. The bottom side of the biosynthesis tank 5 is connected to the top of the first pipe 8 and the non-polar column filter tank 3. A light shield 4 is provided on the outside of the biosynthesis tank 5. Methyltetrahydrofolate is easily decomposed by light, so the reaction is protected from light. A heating plate 22 is provided at the bottom of the biosynthesis tank 5. The heating plate 22 can heat the solution inside the biosynthesis tank 5 to ensure that the enzyme reaction is carried out under mild conditions.
[0029] A first pump body 7 is installed on the first pipe 8. The first pump body 7 is located at the top of the non-polar column filter tank 3. One side of the liquid outlet end of the bottom of the non-polar column filter tank 3 is connected to the bottom side of the collection tank 2 through the third pipe 13 for easy pumping. A second pump body 10 is installed on the third pipe 13. The bottom end of the stirring shaft 19 penetrates the bottom wall of the biosynthesis tank 5 and is connected to the output end of the reducer. The reducer is located inside the base 1. The input end of the reducer is connected to the motor 18. The motor 18 drives the stirring shaft 19 to rotate through the reducer, making the methyltetrahydrofolate reaction more uniform and rapid. The motor 18 is located inside the base 1. A water pipe 15 is installed at the top of the catalytic tank 9. An oxygen pipe 21 is installed on one side of the top of the catalytic tank 9, through which the oxygen generated by the reaction flows out. A cover is installed at the top of the collection tank 2. The bottom of the biosynthesis tank 5 is connected to the bottom of the catalytic tank 9 through the second pipe 11. A third pump body 12 is installed on the second pipe 11.
[0030] Working principle: In the actual production of methyltetrahydrofolate, firstly, pure water is introduced into the catalytic tank 9 through water pipe 15, and carbon dioxide gas is introduced into the catalytic tank 9 through gas supply pipe 17. At this time, the aurora column 20 emits light, and carbon dioxide and water react to produce methyltetrahydrofolate. Then, the third pump body 12 introduces liquid methyltetrahydrofolate into the biosynthesis tank 5 through the second pipe 11. The protein ligand of the catalytic protease is introduced into the biosynthesis tank 5 through the feed pipe 6 to promote the further reaction of carbon dioxide and water to produce methyltetrahydrofolate. At the same time, the motor 18 drives the stirring shaft 19 to rotate through the reducer to make the reaction of methyltetrahydrofolate more uniform and rapid. Then, the first pump body 7 introduces the mixed liquid containing methyltetrahydrofolate into the non-polar column filter tank 3 through the first pipe 8 for filtration. The filtered methyltetrahydrofolate then enters the light-shielded collection tank 2 through the third pipe 13 and the second pump body 10, and then proceeds to the next solid purification process.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
