System, method, and reaction apparatus used for continuous reaction process for preparation of trifluoroethane

A system for preparing trifluoroethane through continuous reaction, comprising:

• a vinylidene chloride liquid feed pipeline and a hydrogen fluoride feed pipeline, the vinylidene chloride liquid feed pipeline and the hydrogen fluoride feed pipeline are in communication with a rotary cutting component and a submersible pump;
• a housing comprising a reaction chamber body and a gas exit passageway in communication with the reaction chamber body;
• the rotary cutting component arranged inside the reaction chamber body, wherein the rotary cutting component comprises an annular filler and a liquid distributor located in a center of the annular filler, and threads are formed on a surface of the annular filler used for cutting a fluid into micro/nanoscale fluid micro elements;
• the submersible pump arranged at a bottom of the reaction chamber body;
• and
• a flow deflector comprising two sets of flow-deflecting plates, each set of said flow-deflecting plates comprising a plurality of flow-deflecting plates, the two sets of flow-deflecting plates being respectively fixed on two opposing sidewalls, and adjacent two flow-deflecting plates being in offset alignment, wherein each flow-deflecting plate is tilted upwards along a direction towards the sidewall on which the flow-deflecting plate is fixed, wherein a plurality of protrusions are formed on a lower surface of each flow-deflecting plate,
• wherein the submersible pump is coupled with a discharge pipeline, and the rotary cutting component is coupled with a feed pipeline.
