Electrode steam boiler waste heat recycling system and electrode steam boiler system

The utility model belongs to the field of high-voltage electrode steam boilers, and particularly relates to an electrode steam boiler waste heat recycling system and an electrode steam boiler system. In order to solve the technical problem that in the prior art, waste heat of high-temperature sewage is not recycled, so that the operation cost of an electrode steam boiler system is high, the utility model provides a waste heat recycling system of an electrode steam boiler. The steam pipeline is used for communicating the blowdown flash tank with the deaerator and/or the water supply tank, and the heat exchanger is used for being arranged between the steam boiler water supply system and the blowdown flash tank. The utility model further provides an electrode steam boiler system using the electrode steam boiler waste heat recycling system. By means of the steam pipeline and the heat exchange device, waste heat of high-temperature sewage in the blowdown flash tank can be effectively utilized, and the technical ef
