The invention discloses a chloroethane recovery and absorption system and method in an alkyl metal production process, the chloroethane recovery and absorption system comprises a buffer tank, a vacuum pump, a leaching tower, a solvent pump, a condenser, a recovery tank and a connecting pipeline, the buffer tank is connected with the vacuum pump through the connecting pipeline, the vacuum pump is connected with the leaching tower through the connecting pipeline, and the leaching tower is connected with the condenser through the connecting pipeline. The condenser is connected with the recovery tank through a connecting pipeline, and the upper end and the lower end of the leaching tower are connected with the solvent pump through connecting pipelines. The chloroethane recovery and absorption system solves the problems that an existing chloroethane absorption device is incomplete in absorption and cannot perform integrated recovery operation, resource waste is caused, efficiency is greatly reduced, operation safe
