Rotating wheel replacement method for flue gas total heat recovery system and heat supply system

The invention discloses a turning wheel replacement method for a flue gas total heat recovery system and a heat supply system.The flue gas total heat recovery system comprises at least two waste heat recovery modules and a control module, each waste heat recovery module comprises a turning wheel device, a boiler in the heat supply system is connected with each waste heat recovery module, and the turning wheel device is connected with the control module. The rotating wheel replacement method comprises the steps that the use state of a rotating wheel device in a target waste heat recovery module which is running is obtained; whether the use state is an abnormal state or not is judged, and if yes, the workload borne by the target waste heat recovery module is transferred to the replacement waste heat recovery module; adjusting the power of the replacement waste heat recovery module which increases the workload; and the target waste heat recovery module is shut down to replace the rotating wheel device.
