The utility model relates to a chloroethylene degreaser which comprises a sealed barrel body. The chloroethylene degreaser is characterized in that an upper sealing head is arranged at the upper end of the barrel body; a gas phase outlet pipe is arranged at the top of the upper sealing head; a baffle plate I is arranged in a position, connected with the barrel body, in the upper sealing head; a gas phase inlet pipe is arranged at the lower part of the inside of the barrel body; one end of the gas phase inlet pipe is positioned on the outer side surface of the barrel body; the other end of the gas phase inlet pipe is arranged on a supporting plate on the inner side surface of the barrel body; a lower sealing head is arranged at the lower end of the barrel body; a discharge port is formed in the position, connected with the outside of the barrel body, of the lower sealing head; a baffle plate II is arranged at the lower part of the inside of the lower sealing head; a dirt discharge port is formed in the bottom of the lower sealing head; and an adsorbent is arranged between the baffle plate I and the baffle plate II. When the chloroethylene degreaser is used for degreasing a high-temperature chloroethylene gas, the degreasing rate is improved and the quality of the chloroethylene gas is improved. Meanwhile, the chloroethylene degreaser has the advantages of being simple and reasonable in structure, simple to operate and less in investment. Thus, the chloroethylene degreaser can be widely applied to a gas degreasing process and is particularly suitable for a chloroethylene gas degreasing process.
