1. A system for reclaiming corrosion inhibitor in a heat exchange system including a compressor, a condenser and an evaporator connected in sequence, wherein the system for reclaiming corrosion inhibitor comprises:
an ejector comprising a high-pressure fluid inlet connected to an outlet of the compressor, a suction fluid inlet connected to the heat exchange system to extract a liquid-state refrigerant in the heat exchange system, and a fluid outlet leading to bearings of the compressor, wherein a pressurizing device is provided between the outlet of the compressor and the high-pressure fluid inlet of the ejector;
wherein the pressurizing device is an additional compressor.
