Chloroethane separation system

The invention discloses a chloroethane separation system, which comprises a chloroethane separation device base, an impurity discharging pipe, a condensing pipe, a water storage box, a chloroethane separation device body, a chloroethane steam passage and a guide plate, wherein the chloroethane separation device body is welded on the top surface of the chloroethane separation device base; a pipeline connecting seat is welded on the top surface of the chloroethane separation device body; a mixed steam inlet passage is arranged at the bottom of the inner side of the chloroethane separation devicebody. The caliber from the inlet position of the mixed steam inlet passage and the outlet position is gradually reduced, so that the chloroethane mixed gas can be extruded so as to lower the temperature of the chloroethane mixed gas; a great amount of cooling water can be stored in the water storage box in one step; the problem of frequent change of cooling water of the existing equipment is avoided; through a temperatur
