The invention discloses a method for recycling phosgene in a continuous production process of toluene di-isocyanate, comprising the following steps: importing gas streams generated in the preparation process of the toluene di-isocyanate to the bottom of a first phosgene absorption tower and leading in inert organic solvent to the first phosgene absorption tower to absorb; separating the gas streams exhausted from the top of the first phosgene absorption tower by a phosgenation reaction flash separator lead in by a liquid ejector pump and leading the acquired gas streams into a second phosgeneabsorption tower; leading part of tower bottom absorption solution in the first phosgene absorption tower which is pressurized by the tower bottom liquid pump of the first phosgene absorption tower to the second phosgene absorption tower and leading in inert organic solvent to the second phosgene absorption tower to absorb; and reusing the phosgene inert organic solvent solution acquired from thebottom of the second phosgene absorption tower to the continuous production process of the toluene di-isocyanate. The method reduces the investment on a large-scale compressor and reduces the cost onoperation and maintenance, thereby achieving the purpose of recycling the phosgene at a lower cost.
