Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, specifically to an anti-reflux condenser for esterification reactions. Background Technology

[0002] Esterification is a type of organic chemical reaction in which an alcohol reacts with a carboxylic acid or an oxygen-containing inorganic acid to form an ester and water. The esterification reaction of a carboxylic acid with an alcohol is reversible. A typical esterification reaction is the reaction of ethanol and acetic acid to produce ethyl acetate, which has an aromatic odor and is a raw material for the manufacture of dyes and pharmaceuticals. Esterification is widely used in fields such as organic synthesis.

[0003] In existing reactor equipment, during the esterification reaction, the product contains water, which easily forms water vapor that adsorbs onto the inner wall of the reactor. After condensation, the water vapor turns into droplets and flows back into the reactor, affecting the forward progress of the reaction. To address this, we propose an anti-reflux condenser for the esterification reaction. Utility Model Content

[0030] The condensing mechanism is mounted on the cover 2 and includes a motor 4, a condensing plate 5, and multiple connecting plates 6. The motor 4 is mounted on the cover 2. The condensing plate 5 and the multiple connecting plates 6 are all fixedly connected inside the cover 2. A condensing tube is installed inside the condensing plate 5, and both ends of the condensing tube are connected to an inlet pipe 7 and an outlet pipe 8, respectively. Both the inlet pipe 7 and the outlet pipe 8 pass through the cover 2. The output end of the motor 4 passes through the cover 2 and is fixedly connected to a fixed shaft 9. The fixed shaft 9 passes through the condensing plate 5 and is fixedly connected to two support plates 1. 0. A scraper 11 is detachably connected to the support plate 10. A guide groove 12 is fixedly connected between the support plate 10 and the fixed shaft 9. An outlet is opened on the guide groove 12. A collection tank 13 is fixedly connected between multiple connecting plates 6. A drain pipe 14 is connected to the collection tank 13. The drain pipe 14 passes through the cover plate. A valve is installed on the drain pipe 14. The condenser pipe, the inlet pipe 7, etc. are used to inject coolant. The condenser plate 5 is used to condense steam. The scraper 11, the guide groove 12, etc. are used to scrape off water droplets and guide them, and then the condensed water is discharged.

[0031] A rotating ring 15 is rotatably sleeved on the collection tank 13. Two support frames 16 are fixedly connected to the rotating ring 15. Support seats are fixedly connected to the support frames 16. The support seats are fixedly connected to the guide channel 12 and the support plate 10 to provide a certain support effect and improve the stability of the support plate 10.

[0032] The support plate 10 has two detachable threaded grooves, and the scraper 11 is fixedly connected to the mounting plate 17. The mounting plate 17 has two mounting holes, and bolts 18 are placed in the mounting holes. The bolts 18 are threaded into the threaded grooves for easy disassembly and replacement of the scraper 11.

[0033] The support plate 10 has a positioning groove 19, and the mounting plate 17 is fixedly connected to a positioning block 20. The positioning block 20 is located in the positioning groove 19 and is used to quickly position the mounting plate 17 to facilitate the installation of bolts 18.

[0037] In summary, the working principle and process of the anti-backflow condenser for esterification reaction are as follows: First, place the anti-backflow condenser at the desired location. Then, when using it, connect the inlet pipe 7 and outlet pipe 8 to the external coolant pipeline. The coolant enters the condenser tube, cooling the condenser tube and condenser plate 5. Then, the vapor generated by the esterification reaction in the reactor body 1 will be condensed into water droplets by the condenser plate 5. At this time, start the motor 4. The motor 4 drives the fixed shaft 9 to rotate, and the fixed shaft 9 drives the support plate 10, scraper 11, etc. to rotate. The scraper 11 scrapes off the condensed water droplets, which will flow into the collection tank 13 through the guide channel 12. When it is necessary to discharge the condensed water droplets, the operator can open the valve to discharge the condensed water droplets, effectively preventing the condensed water droplets from flowing back and improving practicality.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
