Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a hexachloroethane reaction vessel that is easy to clean. Background Technology

[0002] After dehydration, tetrachloroethane is reacted at 90-100℃. When the reaction solution changes from turbid to clear and crystals appear, chlorination is stopped. The temperature is then raised to 120℃ to remove residual chlorine. After discharge, the material undergoes hot water washing, neutralization, centrifugal filtration, and finally drying and pulverizing to obtain the final product.

[0003] Tetrachloroethane and chlorine typically react in a vacuum reactor. After the reaction is complete and the material is discharged, the inside of the reactor usually needs to be cleaned. Currently, most methods involve manual rinsing through the cleaning port. Some methods use cleaning pipelines installed inside the reactor. However, existing cleaning pipelines require fixing to the inner wall of the reactor using fasteners. To install these fasteners, screw holes need to be drilled in the inner wall of the reactor. Furthermore, the pipelines have poor stability and a short service life. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

A jacket 7 is provided around the vessel body 1. A heat exchange medium inlet 20 is provided at the lower part of the jacket 7, and a heat exchange medium outlet 21 is provided at the upper part of the jacket 7. Several support seats 22 are also provided around the jacket 7. The heat exchange medium (such as hot gas or hot oil) enters the jacket 7 through the heat exchange medium inlet 20 and the heat exchange medium outlet 21, thereby achieving... The heating inside the reactor body 1 is achieved by supporting and fixing the reactor body through the support base 22. A chlorine gas inlet 16 is provided at the lower part of the side wall of the reactor body 1. The chlorine gas inlet 16 passes through the jacket 7 and is connected to the inside of the reactor body 1.

A thermometer port 18 and a pressure gauge port 19 are provided on the side wall of the reactor body 1 to install a thermometer and a pressure gauge respectively, thereby realizing the monitoring of the temperature and pressure inside the reactor body 1.

[0022] The water distribution plate 8 is bolted to the lower surface of the vessel cover 2. The upper surface of the water distribution plate 8 has an annular groove 9. The side wall of the water distribution plate 8 has several side water outlet holes 10. The water distribution plate 8 is located at the annular groove 9 and has several bottom water outlet holes 11 along the axial direction. The upper surface of the vessel cover 2 is provided with a water inlet 12, which is connected to the annular groove 9 of the water distribution plate 8. A central hole is provided at the center of the water distribution plate 8. A bearing sleeve 13 is provided at the central hole of the water distribution plate 8. The stirring shaft 4 passes through the bearing sleeve 13 and cooperates with the bearing sleeve 13.
