Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction equipment, in particular to a vertical dynamic tube reactor. Background Technique

[0002] In chemical process plants, reactors are one of the common process equipment and are the core places for raw materials to be converted into products, providing necessary controllable conditions such as pressure, temperature, and flow rate for chemical reactions.

[0003] The existing patent (publication number: CN218901832U) discloses a new type of vertical dynamic tube reactor, which includes a reaction device, a sealing device, and a power device. The reaction device includes a stirring shaft, a cylinder body, and an outer jacket. The cylinder body is a vertical cylinder body, and a stirring shaft is arranged inside the cylinder body. The stirring shaft is connected to the cylinder body through the flange plates at both ends of the cylinder body; the stirring shaft adopts a hollow structure to form a first heat exchange cavity, and the opposite ends of the stirring shaft are respectively provided with a first connection end and a second connection end; the outer jacket is arranged outside the cylinder body, and the opposite ends of the outer jacket are also respectively connected to the first connection end and the second connection end. A second heat exchange cavity is formed between the outer jacket and the cylinder body; a mechanical seal is adopted between the stirring shaft and the cylinder body. The new type of vertical dynamic tube reactor adopts a vertical tube space structure, which can achieve high mass transfer efficiency and high heat transfer efficiency, and effectively solves the "backmixing" phenomenon that occurs when gas phase participates.

[0004] The reactor in the above patent technology provides cooling water through a water storage tank to exchange heat with the heat generated during the reaction in a water-cooling manner, so as to dissipate heat and maintain the normal temperature inside. After the cooling water undergoes heat exchange, the heat of the cooling water will increase, resulting in a worse and worse subsequent cooling and heat dissipation effect, and it is impossible to achieve a good cooling and heat dissipation effect. Therefore, a vertical dynamic tube reactor is proposed. Content of the Utility Model

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6, the present utility model provides a technical solution: a vertical dynamic tube reactor, including a base 1. The outer surface of the top of the base 1 is fixedly connected with a reaction cylinder 2 and a water storage cylinder 3. A spiral tube 4 is connected inside the reaction cylinder 2. A water pump 5 is fixedly installed on the outer surface of the top of the base 1. The input end of the water pump 5 is fixedly communicated with a water suction pipe 6, and the output end of the water pump 5 is fixedly communicated with a drain pipe 7. The water suction pipe 6 is fixedly communicated with the inside of the water storage cylinder 3. One end of the drain pipe 7 away from the water pump 5 is fixedly communicated with the inside of the spiral tube 4. One end of the spiral tube 4 away from the drain pipe 7 is fixedly communicated with a circulation pipe 9, and the other end of the circulation pipe 9 is fixedly communicated with the inside of the water storage cylinder 3. A refrigeration pipe 8 is arranged inside the water storage cylinder 3, and the other end of the refrigeration pipe 8 is fixedly communicated with the output end of an external refrigerator. A number of rotating shafts 10 are arranged inside the spiral tube 4, and a number of first spoiler plates 11 are arranged on the outer surfaces of the number of rotating shafts 10. In this embodiment, when performing heat exchange, the water pump 5 is turned on. The water pump 5 pumps out the cooling water in the water storage cylinder 3 through the water suction pipe 6 and pumps it into the spiral tube 4 through the drain pipe 7. Heat exchange is carried out by the cooling water and the heat generated during the reaction process. After the cooling water enters the spiral tube 4, under the action of the water flow, the first spoiler plates 11 cause turbulence to the water flow, making the heat exchange effect better. And the cooling water enters the water storage cylinder 3 through the circulation pipe 9. The refrigerator delivers cold air to the refrigeration pipe 8, and heat exchange is carried out between the refrigeration pipe 8 and the cooling water, keeping the cooling water in a cooled state, thus ensuring the cooling and heat dissipation effect.

[0026] A reaction tube 12 is arranged inside the base 1. One end of the reaction cylinder 2 is fixedly communicated with a feed pipe 16, and the feed pipe 16 extends to the outside of the reaction cylinder 2. A number of fixed shafts 13 are arranged inside the reaction tube 12, bearings 14 are sleeved on the outer surfaces of the fixed shafts 13, and a number of second spoiler plates 15 are fixedly connected to the outer rings of the bearings 14. In this embodiment, when the reaction substances enter the reaction tube 12, under the action of the fluid flow, the outer ring of the bearing 14 drives the second spoiler plates 15 to rotate, making the movement trajectory of the fluid irregular and changing the uniform flow field during the flow of the fluid in the reaction tube 12, thus being conducive to the full mixing of the reaction substances.

[0027] A connecting pipe 17 is fixedly connected to the outer surface of the top of the feed pipe 16, a funnel cylinder 18 is fixedly communicated with the outer surface of the top of the connecting pipe 17, pressure relief holes 21 are formed on the outer surface of the funnel cylinder 18, a spring 19 is fixedly connected to the inner surface of the top of the funnel cylinder 18, and a plug 20 is fixedly connected to the outer surface of the bottom of the spring 19. In this embodiment, when the pressure inside the reaction tube 12 reaches a certain level, under the action of the pressure, the plug 20 is pushed up and the spring 19 is compressed, and the pressure is balanced from the pressure relief holes 21, so that there is enough pressure inside the reaction tube 12 to enable the substances to react fully, and thus the substances can react fully with each other.

[0028] The outer surface of the reaction cylinder 2 is provided with a number of heat dissipation fins. In this embodiment, the heat dissipation fins are used to enhance the heat dissipation and cooling effect.

[0029] A movable rod is movably inserted into the outer surface of the top of the funnel cylinder 18. The bottom outer surface of the movable rod is fixedly connected to the blocking block 20. The spring 19 is sleeved on the outer surface of the movable rod. In this embodiment, by providing the movable rod, the spring 19 is prevented from deforming obliquely.

[0030] The blocking block 20 is in the shape of a frustum of a cone with a thicker upper part and a thinner lower part. A sealing gasket is fixedly connected to the outer surface of the blocking block 20. In this embodiment, the frustum-shaped blocking block 20 with a thicker upper part and a thinner lower part fits with the funnel cylinder 18, and together with the sealing gasket, the sealing effect is enhanced.

[0031] Working principle: When the present utility model is in use, the reaction substances are conveyed from the feed pipe 16 into the reaction pipe 12. When heat exchange is carried out, the water pump 5 is turned on. The water pump 5 pumps out the cooling water in the water storage cylinder 3 through the water suction pipe 6 and pumps it into the spiral pipe 4 through the drain pipe 7. Heat exchange is carried out between the cooling water and the heat generated during the reaction process. After the cooling water enters the spiral pipe 4, under the action of the water flow, the first flow disturbing piece 11 generates a disturbance to the water flow, making the heat exchange effect better. And the cooling water enters the water storage cylinder 3 through the circulation pipe 9. The cooler conveys cold air to the refrigeration pipe 8, and heat exchange is carried out between the refrigeration pipe 8 and the cooling water, keeping the cooling water in a cooled state, thereby ensuring the cooling and heat dissipation effect.

[0032] When the reaction substances enter the reaction pipe 12, under the action of the fluid flow, the outer ring of the bearing 14 drives the second flow disturbing piece 15 to rotate, making the movement trajectory of the fluid irregular, changing the uniform flow field of the fluid during the flow in the reaction pipe 12, which is beneficial to the full mixing of the reaction substances. When the pressure in the reaction pipe 12 reaches a certain level, under the action of the pressure, the blocking block 20 is pushed up and the spring 19 is compressed, and the pressure is balanced from the pressure relief hole 21, so that there is sufficient pressure in the reaction pipe 12 to enable the substances to react fully, and thus the substances can react fully with each other.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
