Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a cooling reaction tank for stirring in petrochemical processes. Background Technology

[0002] In the petrochemical industry, stirred tank reactors are one of the core pieces of equipment for material mixing and chemical reactions. In many reaction processes, reactants need to be thoroughly stirred under specific temperature conditions to ensure efficient reaction and stable product quality.

[0003] Announcement No. CN211864993U discloses a petrochemical stirring and cooling reaction vessel, comprising a stirring tank and a cooling device. The stirring tank has a horizontally arranged permeable baffle that divides the interior into an upper steam cooling chamber and a lower stirring chamber. The stirring tank wall has a hollow water-cooled jacket. A stirring shaft with a hollow cavity is rotatably connected within the stirring chamber, and symmetrically arranged on the stirring shaft are hollow stirring blades formed by coiled water-cooled pipes. A stirring motor is located at the top of the stirring tank, and the output shaft of the stirring motor extends to the bottom of the stirring shaft and is fixedly connected thereto. The portion of the output shaft located in the steam cooling chamber is connected to an exhaust device via a gear structure.

[0004] The aforementioned petrochemical stirring and cooling reaction tank, by stirring the high-temperature liquid, ensures that the perforated stirring blades are in full contact with the liquid. The circulating cooling medium absorbs the high temperature and discharges the generated vapor, thus accelerating the cooling effect. However, the hollow water-cooled jacket in this device can only cool the surface of the stirred material. The middle part of the material cannot directly contact the jacket, and although the perforated stirring blades stir it out, the heat is difficult to transfer quickly, resulting in a slow cooling rate. This makes it difficult to meet the requirements of rapid and uniform cooling for temperature-sensitive petrochemical reactions. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling reaction tank for petrochemical stirring.

[0006] This utility model is achieved using the following technical solution: a cooling reaction tank for petrochemical stirring, comprising a reaction tank, a feed pipe fixedly connected to the top of the reaction tank, a stirring device installed inside the reaction tank, a support rod fixedly connected to the bottom of the reaction tank, a water inlet pipe fixedly connected to the surface of the reaction tank, a drain pipe fixedly connected to the bottom of the reaction tank, a discharge pipe fixedly connected to the bottom of the reaction tank, a partition fixedly connected inside the reaction tank, the partition separating the interior of the reaction tank into a hollow water-cooled jacket and a stirring chamber, a hollow column fixedly connected in the middle of the partition, and a heat exchange device fixedly connected to the top of the reaction tank.

[0007] Through the above technical solution, the partition separates the interior of the reaction vessel into a hollow water-cooled jacket and a stirring chamber, so that the cooling system and the reaction stirring system are relatively independent yet cooperate with each other, ensuring the cooling effect without affecting the stirring and reaction of the materials.

[0008] As a further improvement to the above solution, the stirring chamber is connected to the feed pipe and the discharge pipe, and the stirring chamber is located inside the hollow water-cooled jacket.

[0009] As a further improvement to the above scheme, the hollow column is connected to the hollow water-cooled jacket, and the hollow column is located inside the stirring chamber.

[0010] Through the above technical solution, the hollow column is connected to the hollow water-cooled jacket and is located inside the mixing chamber, which allows the cooling water to directly exchange heat with the material, playing the role of cooling the material.

[0011] As a further improvement to the above solution, the stirring device includes a motor, and a stirring rod is fixedly connected to the output end of the motor.

[0012] Through the above technical solution, the stirring rod rotates under the drive of the motor, causing the material to flow around the hollow column and form a complex vortex, thereby achieving full mixing of the material and promoting uniform reaction.

[0013] As a further improvement to the above scheme, the motor is located at the top of the reaction vessel, the bottom of the motor is fixedly connected to the top of the reaction vessel, and the stirring rod is located on the outside of the hollow column.

[0014] As a further improvement to the above solution, the heat exchange device includes an outlet pipe, one side of which is connected to a heat exchanger, and a support base is fixedly connected to the surface of the heat exchanger.

[0015] As a further improvement to the above solution, the gas outlet pipe is located at the top of the reaction vessel and is fixedly connected to the top of the reaction vessel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a hollow column. Material enters the mixing chamber through the feed pipe, and a motor drives the stirring rod on the outside of the hollow column to create a vortex for thorough mixing. Cooling water enters the hollow water-cooled jacket through the inlet pipe, and exchanges heat with the material through the hollow column. After heat exchange, the water is discharged through the drain pipe, which can quickly remove the heat generated by the reaction, effectively control the reaction temperature, and ensure that the reaction takes place under suitable temperature conditions, avoiding adverse effects on the reaction and equipment due to excessively high temperatures.

[0018] This invention incorporates a heat exchanger, where the hot gas generated during the reaction is introduced into the heat exchanger through a top outlet pipe. With the support base in place, the heat exchanger performs heat recovery processing on the hot gas, thereby achieving heat recovery and utilization, improving energy efficiency, and reducing energy consumption.

A hollow column 11 is fixedly connected in the middle of the partition 8. A heat exchange device 12 is fixedly connected to the top of the reaction tank 1. Material enters the stirring chamber through the feed pipe 2. 10. The top motor 301 drives the stirring rod 302 located outside the hollow column 11 to rotate, causing the material to flow around the hollow column 11 and form a complex vortex, achieving thorough mixing. The water inlet pipe 5 injects cooling water into the hollow water-cooled jacket 9. Since the hollow column 11 is connected to the jacket and is located inside the stirring chamber 10, the cooling water directly exchanges heat with the material generated by the cross-convection of the material stirred by the stirring rod 302 in the hollow column 11, quickly removing the heat of the reaction. The cooling water after heat exchange is discharged from the drain pipe 6, which can quickly remove the heat generated by the reaction, timely and effectively control the reaction temperature, ensure that the reaction is carried out under suitable temperature conditions, and avoid adverse effects on the reaction and equipment due to excessive temperature.

[0029] The stirring chamber 10 is connected to the feed pipe 2 and the discharge pipe 7, and the stirring chamber 10 is located inside the hollow water-cooled jacket 9.

[0030] The hollow column 11 is connected to the hollow water-cooled jacket 9, and the hollow column 11 is located inside the stirring chamber 10.

[0031] The stirring device 3 includes a motor 301, and a stirring rod 302 is fixedly connected to the output end of the motor 301.

A support base 123 is fixedly connected to the surface of the heat exchanger 122. The hot gas generated during the reaction is introduced into the heat exchanger 122 through the top outlet pipe 121. With the support base 123 fixed, the heat exchanger 122 performs heat recovery treatment on the hot gas, realizes heat recovery and utilization, improves energy utilization efficiency, and reduces energy consumption.

[0034] The vent pipe 121 is located at the top of the reaction vessel 1 and is fixedly connected to the top of the reaction vessel 1.

[0035] The implementation principle of a petrochemical stirring and cooling reaction tank in this embodiment is as follows: Material enters the stirring chamber 10 through the feed pipe 2. The top motor 301 drives the stirring rod 302 located outside the hollow column 11 to rotate, causing the material to flow around the hollow column 11 and form a complex vortex, achieving thorough mixing. Cooling water is injected into the hollow water-cooled jacket 9 through the water inlet pipe 5. Because the hollow column 11 is connected to the jacket and located inside the stirring chamber 10, the cooling water directly exchanges heat with the material through the cross-convection generated by the stirring of the hollow column 11 and the stirring rod 302, quickly removing the heat of reaction. The cooling water, after heat exchange, is discharged from the drain pipe 6, which can quickly remove the heat generated by the reaction, effectively control the reaction temperature, ensure that the reaction is carried out under suitable temperature conditions, and avoid adverse effects on the reaction and equipment due to excessive temperature. The hot gas generated during the reaction is introduced into the heat exchanger 122 through the top vent pipe 121.
