[0002] In the process of preparing trifluoromethylthionyl chloride using trifluorobromomethane as a raw material, it is necessary to recycle the unreacted trifluorobromomethane in the synthesis reactor. The existing trifluorobromomethane recycling equipment mainly includes a synthesis reactor and a recovery tank, and the remaining trifluorobromomethane in the synthesis reactor is recycled to the recovery tank.

[0003] After searching, the utility model patent with announcement number CN202131245U discloses a recycling equipment for bromotrifluoromethane, including a synthesis reactor and a recovery tank. There are more than two synthesis reactors, and the multiple synthesis reactors are connected in series. The residual gas in the synthesis reactor that has finished the reaction first enters another synthesis reactor for reaction. The bromotrifluoromethane outlet of the synthesis reactor is connected to the recovery tank; the patent greatly reduces the consumption of bromotrifluoromethane by connecting multiple synthesis reactors in series; the tail gas absorption load is reduced, and the damage to the atmosphere is cured. However, the above patent still has the following shortcomings: heat is generated when the compressor is running, and the heat generated by the compressor when it is running is not dissipated in time, which will affect its working quality and service life. For this reason, we propose an automatic bromotrifluoromethane recovery device with good heat dissipation effect. Utility Model Content

[0027] In this embodiment, the water in the water tank 4 is cooled by the cooling surface of the semiconductor refrigeration sheet 12, and the heat dissipation fins 13 on the outside of the semiconductor refrigeration sheet 12 are used to dissipate the heat generated when the semiconductor refrigeration sheet 12 is in operation.
