Description

Technical Field

[0001] The utility model belongs to the field of reactors, and in particular relates to a reactor with uniform heat exchange and convenient cleaning. Background Art

[0002] Reactors are pressure vessels used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. They are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. With the demand for various chemical reactions, the multifunctionality of reactors has become one of the hottest trends in reactor development.

[0003] A reactor typically consists of a reactor body, a heat transfer device, a stirring mechanism, a transmission mechanism, and a shaft seal. This heat transfer mechanism typically utilizes coiled tubes within the reactor body for heat exchange. In some chemical operations, significant amounts of heat exchange are required to meet these demands. Existing methods for enhancing heat exchange involve increasing stirring and the heat exchange area. However, due to the limited surface area of ​​the reactor's inner wall, the effective placement of heat exchange tubes and the arrangement of stirring mechanisms are difficult, thus impacting heat exchange efficiency. Furthermore, increasing the length of the coiled tube within the reactor body increases flow resistance and slows flow rates, resulting in ineffective heat exchange enhancement. Furthermore, considering the uniformity of actual heat exchange, conventional heat exchange tubes struggle to achieve uniform and efficient heat exchange.

[0004] Moreover, it is very inconvenient to clean the traditional reactor. Usually, the reactor needs to be opened or a cleaning mechanism needs to be added to clean it from the inside, which greatly reduces the working efficiency of the reactor and also shortens its service life.

[0005] Therefore, it is an issue that needs to be considered at present to propose a reactor with uniform heat exchange and easy cleaning, which can not only have better uniform heat exchange but also reduce the cost of cleaning the reactor. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Please see the attached Figure 1 With attached Figure 2 A reactor with uniform heat exchange and easy cleaning includes a reactor body, a heat exchange layer 4, a stirring mechanism and an infrared spraying device 13; the heat exchange layer 4 is evenly arranged on the outer surface of the reactor body to achieve uniform heat exchange of the raw material liquid inside the reactor body; the stirring mechanism extends from the top of the reactor body to the inside of the reactor body, and is driven by an external force so that the stirring mechanism can stir the raw material liquid inside the reactor body to accelerate the reaction efficiency of the raw material liquid; the infrared spraying device 13 is arranged on the stirring mechanism inside the reactor body, and cleans the inner wall of the reactor body through its own rotating spraying.

[0026] A motor fixing device 2 is fixedly provided at the top of the reactor body, a liquid guide tube 16 is provided inside the motor fixing device 2, and a liquid guide tube inlet 17 is provided at the upper end of the motor fixing device 2; a feed pipe inlet 3 is provided on one side of the upper end of the reactor body, and the feed pipe inlet 3 is arranged on the feed pipe, and the feed pipe extends into the interior of the reactor body. A feed pipe fixing device 7 is fixedly provided around the feed pipe extending into the interior of the reactor body, and the bottom end of the feed pipe is a feed pipe outlet 8, which is located above the bottom inner wall of the reactor body; a discharge port 9 is provided at the bottom of the reactor body, and the discharge port 9 is located directly below the stirring mechanism.

[0027] Heat exchange layer 4 is provided with a heat exchange tube inlet 5 on its left side and a heat exchange tube outlet 15 on its right side. Heat exchange liquid flows into heat exchange layer 4 from inlet 5, exchanges heat with the raw material liquid inside the reactor body, and is then discharged through outlet 15, achieving a heat exchange effect on the reactor body. Heat exchange layer 4 is surrounded by an insulation layer 6, which reduces heat loss during the heat exchange process and effectively improves heat conversion efficiency.

[0028] The stirring mechanism includes a motor 1, a stirring shaft 11, and stirring blades 10. The motor 1 is fixedly mounted on a motor fixture 1. One end of the stirring shaft 11 is fixedly mounted on the output end of the motor 1, and the other end extends downward into the interior of the reactor body and is fixedly connected to the stirring blades 10. Driven by the electric power of the motor 1, the stirring shaft 11 drives the stirring blades 10 to rotate, thereby stirring the raw material liquid in the reactor body. The stirring shaft 11 is also provided with an upper sleeve 14 and a lower sleeve 12, both of which are connected to a liquid guide tube 16.

[0029] A spray port 18 is provided at the center of the outermost end of the infrared spray device 13. The infrared spray device 13 is respectively arranged on the upper sleeve 14 and the lower sleeve 12. The infrared spray device 13 can receive infrared signals and rotate horizontally 360 degrees without dead angles with the upper sleeve 14 or the lower sleeve 12 as the central axis. When the heat exchange reaction of the raw material liquid in the reactor body is completed, the raw material liquid is discharged from the reactor through the discharge port 9. At this time, some raw material liquid may remain on the inner wall of the reactor body. If it is not cleaned in time, it will corrode the reactor body on the one hand and may affect subsequent reactions on the other hand. At this time, it is only necessary to open the infrared spray device 13 by infrared remote control and inject clean water from the liquid guide tube inlet 17. The clean water is introduced into the infrared spray device 13 through the liquid guide tube 16 and can be sprayed along the spray port 18 on the infrared spray device 13 onto the inner wall of the reactor body, thereby cleaning the residual liquid on the inner wall of the reactor body.

[0030] As an example of the present invention, the motor 1 can adjust the output power to achieve the rotation rate of the stirring shaft 11 and the stirring blade 10, thereby adapting to different types of raw material liquids and different degrees of heat exchange reactions.

[0031] As an example of the present invention, the stirring shaft 11 is a telescopic rod, and the extension length of the stirring shaft 11 can be adjusted according to the actual height of the raw material liquid, and the height of the stirring blade 10 can be adjusted to achieve rapid and uniform stirring of different depths of the raw material liquid.

[0032] As an example of the present invention, a plurality of spray ports 18 are provided at the outermost end of the infrared spray device 13 to improve the water spraying efficiency and the cleaning efficiency of the inner wall of the reactor body.

[0033] As an example of the present invention, the liquid conduit inlet 17 can be connected to a water pump to pump clean water from the liquid conduit inlet 17 into the liquid conduit 16 to increase the water pressure and increase the water outlet rate of the spray port 18.

[0034] The working principle of the present invention is as follows: when the raw material liquid enters the reactor from the feed pipe inlet 3 along the feed pipe downward, the raw material liquid flows from the feed pipe outlet 8 to the bottom of the reactor body, preventing the raw material liquid from falling directly from a high place to the bottom of the reactor, causing a reaction accident. As the raw material liquid continues to be injected, the liquid level of the raw material liquid gradually rises. At this time, the heat exchange liquid is injected into the heat exchange layer 4 from the heat exchange pipe inlet 5, and the motor at the top of the reactor is started. Under the operation of the motor, the stirring shaft 11 drives the stirring blade 10 to rotate at high speed. The high-speed rotating stirring blade 10 will stir the raw material liquid in the reactor at high speed, causing a heat exchange reaction in the reactor. After the continuous heat exchange liquid is heat-exchanged in the heat exchange layer 4, it is discharged from the heat exchange layer 4 through the heat exchange pipe outlet 15. When the reaction of the raw material liquid in the reactor is completed, the motor 1 is turned off, the stirring blade 10 stops stirring the raw material liquid, and the discharge port 9 is opened to discharge the raw material liquid that has completed the reaction from the discharge port 9 to the reactor. At this point, infrared spray device 13 is activated, rotating around upper sleeve 14 or lower sleeve 12. Cleaning fluid is injected into liquid guide tube inlet 17. The cleaning fluid enters infrared spray device 13 through liquid guide tube 16 and is ultimately sprayed from spray port 18 onto the inner wall of the reactor, cleaning the inner wall and removing any residue. The residue and cleaning fluid accumulate under gravity at the bottom of the reactor and are discharged from discharge port 9, completing the reactor cleaning process.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
