Reinforced descaling type heat exchange device

The invention relates to a reinforced descaling type heat exchange device, and belongs to the technical field of energy sources. The reinforced descaling type heat exchange device can solve the problems of scale formation and low heat exchange efficiency in the unclean water and clean water heat exchange process. An unclean water inlet and two unclean water outlets are formed in an electric rotary reversing valve, one of the two unclean water outlets is communicated with an unclean water inlet of a first heat exchanger, the other unclean water outlet is communicated with an unclean water inlet of a second heat exchanger, unclean water outlets of the two heat exchangers are communicated with an unclean water outlet main pipeline, when the unclean water inlet is communicated with one of the two unclean water outlets, the unclean water inlet is not communicated with the rest one of the two unclean water outlets, when the unclean water inlet is not communicated with one unclean water outlet of the electric rotary reversing valve, the unclean water inlet is communicated with the rest one of the unclean water outlets, and two clean water branch pipeline outlets are respectively communicated with the clean water inlets of the two heat exchangers. The reinforced descaling type heat exchange device is used for unclean water and clean water heat exchange.
