Description

Technical Field

[0001] This utility model relates to the field of chemical reaction vessel technology, specifically to a thermal circulation chemical reaction vessel. Background Technology

[0002] Thermal circulation chemical reactors achieve the recycling of heat to meet the temperature requirements of the reaction, thereby ensuring the smooth progress of the chemical reaction.

[0003] A search revealed that patent document CN221182738U discloses a thermal circulation chemical reactor. When the reactor needs to be kept warm by the hot gas generated by the reactor body, multiple cavities are formed around the reactor body through staggered baffle plates 1 and 2, in conjunction with a protective cover. The multiple cavities are connected in an S-shape by through holes 1 and 2, thus forming a hot gas passage. When it is necessary to keep the reactor body warm, the hot gas generated by the reactor body is introduced into the inlet of the formed hot gas passage. The hot gas passes through multiple cavities in sequence and is discharged outward, thus circulating around the reactor body, achieving heat preservation and heating of the reactor body, and effectively utilizing the generated hot gas.

[0004] However, during the use of the reactor, when it is necessary to add reaction additives into the reactor, the raw materials inside the reactor have a certain temperature, while the additive itself has a lower temperature. This will cause the additive to cool down the raw materials inside the reactor when it enters the reactor, which can easily affect the materials in the reaction process and reduce the stability of the reaction. Utility Model Content

[0005] In view of the problems existing in the current thermal circulation chemical reactor, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a thermal circulation chemical reactor that solves the problem that the low-temperature additives added during the use of existing reactors can easily affect the reaction process already underway inside the reactor.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A thermal circulation chemical reactor includes a reactor body and a heat-conducting ring sleeved on the lower outer side of the reactor body. A feed pipe is fixedly inserted through the top of the reactor body. The heat-conducting ring is hollow and filled with heat-conducting oil. Two symmetrically arranged vertical pipes are fixedly inserted through the top of the heat-conducting ring. The openings of the two vertical pipes are respectively connected to an inlet pipe and an outlet pipe. A heat-conducting pipe is fixedly sleeved on the wall of the feed pipe. The upper ends of both the inlet pipe and the outlet pipe are connected to the heat-conducting pipe. A pump body is fixedly installed on the top of the reactor body and is fixedly sleeved on the outer wall of the inlet pipe.

[0009] Preferably, the tops of both vertical pipes are connected to the inlet pipe and the outlet pipe via connecting flanges.

[0010] Preferably, the top of the heat-conducting ring is fixed with two symmetrically arranged mounting plates, and each of the two mounting plates is threaded with a locking bolt, the threaded end of which is inserted into the interior of the vessel body.

[0011] Preferably, a plurality of heat-conducting plates are fixedly provided on the lower end of the outer wall of the vessel body in a symmetrical arrangement around it, and the side of the heat-conducting plate is in contact with the inside of the heat-conducting ring.

[0012] Furthermore, an oil change pipe is fixedly inserted through the lower side of the heat-conducting ring, and an oil change valve is fixedly sleeved on the wall of the oil change pipe.

[0013] Preferably, both the feed pipe and the heat pipe are arranged in a spiral shape.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention effectively avoids the cooling effect of low-temperature additives on the reactants inside the reactor by preheating the additives entering the reactor, ensuring the relative stability of the material temperature during the reaction process, reducing reaction abnormalities caused by temperature fluctuations, and significantly improving the stability of the reaction and product quality.

[0016] This invention effectively utilizes the heat generated by the reactor itself to preheat the additives, thereby achieving heat recycling and improving energy efficiency. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a thermal circulation chemical reaction vessel.

[0025] This utility model provides, for example Figure 1-3 The illustrated thermal circulation chemical reactor includes a reactor body 1 and a heat-conducting ring 2 fitted around the lower outer side of the reactor body 1. Two symmetrically arranged mounting plates 11 are fixedly mounted on the top of the heat-conducting ring 2. Locking bolts 12 are threaded through the two mounting plates 11, with the threaded ends of the locking bolts 12 inserted into the reactor body 1. A feed pipe 3 is fixedly mounted on the top of the reactor body 1. The heat-conducting ring 2 is hollow and filled with heat-conducting oil 4. Two symmetrically arranged vertical pipes 5 are fixedly mounted on the top of the heat-conducting ring 2. The openings of the two vertical pipes 5 are respectively connected to an inlet pipe 6 and an outlet pipe 7. The tops of the two vertical pipes 5 are connected to the inlet pipe 6 and the outlet pipe 7 via connecting flanges 10. A heat-conducting pipe 8 is fixedly fitted onto the wall of the feed pipe 3. Both the feed pipe 3 and the heat-conducting pipe 8 are spirally arranged. The upper ends of the inlet pipe 6 and the outlet pipe 7 are connected to the heat-conducting pipe 8. A pump body 9 is fixedly mounted on the top of the reactor body 1, and the pump body 9 is fixedly fitted onto the outer wall of the inlet pipe 6.

[0026] During the chemical reaction, the reaction inside the vessel 1 generates heat, which is transferred to the outer wall of the vessel 1. The heat-conducting ring 2 surrounding the lower outer side of the vessel 1 plays a role. Multiple heat-conducting plates 13 at the lower outer wall of the vessel 1 conduct the heat to the heat-conducting oil 4 inside the heat-conducting ring 2, causing the heat-conducting oil 4 to heat up. When it is necessary to add reaction additives into the vessel 1, the additives enter through the feed pipe 3. Since the wall of the feed pipe 3 is fixedly fitted with a spiral heat-conducting tube 8, the pump body 9 is started. The pump body 9 pumps the heat-conducting oil 4, which has been heated in the heat-conducting ring 2, into the heat-conducting tube 8 through the liquid inlet pipe 6. The heat-conducting oil 4 flows in the spiral heat-conducting tube 8, and fully exchanges heat with the additives in the feed pipe 3, preheating the additives. The temperature of the preheated additives increases and is closer to the temperature of the reactants inside the vessel 1, thereby reducing the impact of the additives on the temperature of the reactants inside the vessel 1 when they enter the vessel 1, ensuring stable mixing of the additives with the reactants inside the vessel 1, and reducing interference with the reaction process.

[0027] In order to make full use of the heat generated during the reaction in vessel 1, such as Figure 3As shown, a plurality of heat-conducting plates 13 are fixedly provided on the lower end of the outer wall of the vessel body 1 in a symmetrical arrangement around it, and the side of the heat-conducting plate 13 is in contact with the inside of the heat-conducting ring 2.

[0028] The heat-conducting plate 13 can transfer the heat generated during the operation of the vessel body 1 and heat the heat-conducting oil 4 inside the heat-conducting ring 2, thus ensuring the effective recycling of heat.

[0029] In order to ensure the heat conduction effect and allow for the replacement of the internal heat conduction oil 4 after prolonged use of the heat conduction ring 2, such as... Figure 3 As shown, an oil change pipe 14 is fixedly inserted through the lower side of the heat conduction ring 2, and an oil change valve 15 is fixedly sleeved on the wall of the oil change pipe 14.

[0030] If the thermal conductivity of the heat transfer oil 4 decreases after prolonged use of the heat transfer ring 2, the oil change valve 15 can be opened, and the old heat transfer oil in the heat transfer ring 2 can be discharged through the oil change pipe 14, and new heat transfer oil can be injected to ensure the heat transfer effect of the heat transfer ring 2 and maintain the normal operation of the entire thermal cycle system.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
