Description

Technical Field

[0001] This utility model relates to the field of acylation equipment technology, specifically to an acylation condenser. Background Technology

[0002] The acyl chloride series products are all produced by reacting o-methylbenzoic acid (m-methylbenzoic acid, p-methylbenzoic acid, 3,5-dimethylbenzoic acid, 2-methyl-3-methoxybenzoic acid) with thionyl chloride to produce crude benzoyl chloride. The crude benzoyl chloride is then purified by distillation to obtain the corresponding finished methylbenzoyl chloride. The acylation reactor is required for the reaction during production. Currently, the acylation reactor is generally used with an acylation condenser to condense the reaction solution.

[0003] CN213434348U discloses a continuous countercurrent acetylation reaction apparatus, in which the water and acylating agent produced by the acetylation reaction are separated by an acylation tower and raised to an acylation condenser. After condensation, the water enters a dilute acid storage tank in the form of a dilute acid. CN214183071U discloses a production apparatus for a difenoconazole intermediate, in which the reaction liquid is fed into an acylation condenser, chilled water is introduced through a chilled water inlet and returned through a chilled water outlet, and the temperature is controlled not to exceed 30°C. Then the liquid is fed into an acylation material high-level tank. The above-mentioned prior art all use an acylation condenser to condense the reaction liquid. However, the cooling water carries heat when it is discharged through the outlet, which causes the cooling effect to decrease after the cooling water is circulated for a period of time.

The condenser body is provided with an air guide assembly, which is connected to the air blowing assembly. The air blowing assembly is used to blow airflow into the air guide assembly, and the air guide assembly is used to guide the airflow so that the airflow flows upward along the periphery of the heat dissipation pipe.

[0015] 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.

[0016] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: An acylation condenser includes a condenser body 1, which is provided with an inlet 2 and an outlet 3. The reaction liquid in the acylation kettle enters through the inlet 2 and is discharged through the outlet 3. A cooling pipe is provided inside the condenser body 1, and one end of the cooling pipe is connected to a cooling water inlet 4, and the other end of the cooling pipe is connected to a cooling water outlet 5. The cooling pipe cools the reaction liquid. Cooling water outlet 5 is connected to heat dissipation pipe 6 spirally wound on the outside of condenser body 1. The heat dissipation pipe 6 is set on the outside of condenser body 1, which can reduce the area occupied and improve practicality. A return pipe 7 is connected to the heat dissipation pipe 6, which recovers and recycles the cooled water. The condenser body 1 is equipped with an air guide assembly, which is connected to the air blowing assembly. The air blowing assembly is used to blow airflow into the air guide assembly, and the air guide assembly is used to guide the airflow so that the airflow flows upward around the heat dissipation pipe 6. The air blowing assembly ensures that the heat dissipation pipe 6 is blown through the air guide assembly, which can remove the heat on the heat dissipation pipe 6, thereby cooling the cooling water after use.

[0017] The air guiding assembly includes two semicircular plates 8, which are connected by a bolt assembly 9, making them detachable. A return pipe 7 passes through one of the semicircular plates 8. Bolt assemblies 11 are provided on both the top and bottom sides of the two semicircular plates 8, and semicircular rings 10 are connected to both the top and bottom sides of the semicircular plates 8 through bolt assemblies 11, making the semicircular rings 10 detachable. The two semicircular rings 10 on the top and bottom sides are in contact with the outer wall of the condenser body 1, forming an air guiding space with the semicircular plates 8 and the outer wall of the condenser body 1. Ventilation pipes 13 are connected to the two semicircular rings 10 on the top and bottom sides, and support rods 12 connected to the condenser body 1 are evenly arranged on the two bottom semicircular rings 10. The support rods 12 are used to support the two bottom semicircular rings 10, thereby supporting the upper semicircular plates 8 and semicircular rings 10. The heat dissipation pipe 6 is located between the two semicircular plates 8 and between the top and bottom semicircular rings 10, allowing airflow to flow around the heat dissipation pipe 6.

[0018] The air blowing assembly includes a fan 15 powered and controlled by existing technology and two transmission channels 14. The air outlet of the fan 15 is connected to one of the transmission channels 14. Both transmission channels 14 are semi-circular in shape and are interconnected. The two transmission channels 14 are respectively connected to the vent pipes 13 on the two bottom semi-circular rings 10. The air inlet of the fan 15 is provided with a filter plate 16. The outside airflow is filtered through the filter plate 16 and then sent to the bottom vent pipe 13 through the transmission channel 14, so that the airflow enters between the semi-circular plate 8 and the condenser body 1, and then blows air onto the heat dissipation pipe 6. Finally, the heat is blocked by the top semi-circular ring 10 and discharged through the top vent pipe 13.

[0019] Heat sink 17 is evenly arranged on the outer side of the condenser body 1, and heat sink 2 18 and heat sink 3 19 are evenly arranged on the inner and outer sides of the semi-circular plate 8. When the airflow passes through, it can also carry away the heat on heat sink 17 and heat sink 2 18, and at the same time help heat sink 3 19 to cool down, thereby helping the condenser body 1 to cool the reaction liquid, and also helping the heat dissipation pipe 6 to cool further.

[0020] The outer side of the semi-circular plate 8 is uniformly provided with miniature electric telescopic rods 20 powered and controlled by existing technology. The output end of the miniature electric telescopic rod 20 is provided with a movable block 21, and the movable block 21 is opposite to the top vent pipe 13. When exhausting, the movable block 21 does not block the top vent pipe 13. When not in use, the top vent pipe 13 is blocked by the miniature electric telescopic rod 20, which can prevent dust and impurities from entering, thereby reducing the dust adhesion on the heat dissipation pipe 6 and thus reducing the impact on heat dissipation. The reason for not using a filter screen is that if the air blows continuously, it is easy to damage the filter screen.

[0021] The second implementation differs from the first implementation in that the movable block 21 is also provided with a sealing gasket 22 opposite to the top vent pipe 13. The sealing gasket 22 can improve the sealing effect with the top vent pipe 13 and better isolate dust and impurities.

[0022] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0023] During use, cooling water flows inside the heat dissipation pipe 6, and the airflow blown out by the bottom vent pipe 13 enters between the semi-circular plate 8 and the condenser body 1, thus ensuring that it flows around the heat dissipation pipe 6 and can cool the heat dissipation pipe 6. The heat carried away is blocked by the top semi-circular ring 10 and discharged through the top vent pipe 13. While carrying away heat, it can also carry away heat from the heat dissipation fin 17 and the heat dissipation fin 18. This not only helps the condenser body 1 cool the reaction liquid, but also helps to further cool the temperature between the condenser body 1 and the semi-circular plate 8, thereby helping to further cool the heat dissipation pipe 6.
