The utility model discloses a ship limited space operation exhaust device which comprises an air blowing mechanism used for conveying pure air into an operation space and an air draft mechanism used for exhausting air in the operation space, and the air blowing mechanism and the air draft mechanism are in transmission connection through a transmission mechanism. Pure air is provided for an operation space through compressed air entering; meanwhile, the kinetic energy of compressed air is utilized, the gear shaft is utilized to drive the air draft mechanism, exhaust of vitiated air in the space is accelerated, the ventilation efficiency in the operation space is improved, meanwhile, the air exhaust device is light in weight, convenient to arrange on site and convenient to use in a narrow space, the ventilation efficiency is guaranteed, meanwhile, the air exhaust device does not need to be driven by electricity, and the cost is low. And the potential safety hazard of electricity utilization caused by the arrang
