Condensation heat recycling device and working method thereof

The invention provides a condensation heat recycling device and a working method thereof. The condensation heat recycling device comprises a steam turbine, a condenser, a circulating cooling water system, a condensate pump, a high-temperature heat pump, a high-low pressure heater and a boiler, the steam turbine discharges steam into the condenser, the condenser is divided into two paths, one path passes through the circulating cooling water system and the high-temperature heat pump to form a loop, the steam is condensed to form condensate and condensation heat is absorbed by the high-temperature heat pump; and the other path sequentially passes through the condensate pump, the high-temperature heat pump, the high-low pressure heater, the boiler and the steam turbine to form the loop, and is used for heating the condensate left at the bottom of the condenser by utilizing the condensation heat in the high-temperature heat pump. According to the condensation heat recycling device and working method thereof, stru
