The utility model discloses a kind of high-temperature steam
heat pump systems based on waste water
waste heat recovery, including
waste heat tank, first heat exchange component, second heat exchange component and third heat exchange component, first heat exchange component includes first
heat exchanger, first
heat pump unit and first flash tank, the outlet
pipe of
waste heat tank is connected with first
heat exchanger, waste water carrying waste heat enters first
heat exchanger and exchanges heat with circulating water, second heat exchange component includes second heat exchanger, second
heat pump unit and second flash tank, the outlet
pipe of second heat exchanger is connected with first heat exchanger, waste water carrying waste heat enters second heat exchanger and exchanges heat with circulating water, third heat exchange component is used to heat first
water supply pump and the supplementary cold water delivered by second
water supply pump;Waste water carrying waste heat exchanges heat by first heat exchanger, second heat exchanger, third heat exchanger and fourth heat exchanger, waste heat is fully released by
cascade utilization, it is favorable to reduce waste heat temperature, with the advantages of high waste heat utilization degree, low comprehensive
energy consumption.
