The invention discloses an online impeller cleaning system for a centrifugal air compressor in an air separation device and a method. The system is mainly composed of a stainless steel water tank, a cleaning water pump, control valves, a check valve, a pressure gauge, a flow meter, pipelines and spray heads; and the cleaning water pump is connected to the stainless steel water tank through a pipeline, is correspondingly connected with the control valves, the pressure gauge and the flow meter through the pipelines behind, adjusts the flow parameters of cleaning water through the connected control valves, the connected pressure gauge and the connected flow meter, and then is connected to the at least two spray heads which are arranged in front of each of a second-stage impeller and a third-stage impeller by two pipelines through the control valves correspondingly. The method comprises the following steps that the cleaning water pump sucks the water from the stainless steel water tank andcompresses the water, th
