The utility model relates to a calcined
coke waste heat utilization
system, and belongs to the technical field of
waste heat recovery. The device comprises a first-stage cooler, a second-stage cooler, a
waste heat lifting device and a
deaerator, and calcined
coke is cooled and output sequentially through the first-stage cooler and the second-stage cooler; the first-stage
cooling pipe is communicated with the heating medium
pipe to form a circulating pipeline, and external
softened water is communicated with a second deoxidizing inlet of the
deaerator through a first
refrigerant pipe; external
softened water is connected with an inlet of the second-stage
cooling pipe through a second
refrigerant pipe, an outlet of the second-stage
cooling pipe communicates with a first inlet of the
deaerator, and an outlet of the deaerator conveys high-temperature water to the outside. The
system is simple in structure, waste heat of calcined
coke can be recycled more sufficiently, energy waste is avoided, steam can be heated by the recycled waste heat of the calcined coke, steam cost is reduced, energy is saved, the
system is stable and reliable, calcined coke materials with the temperature below 100 DEG C can be output, and energy is saved. And the
discharge temperature of the calcined coke is low, so that the requirement on the
cooling temperature of the calcined coke material can be met.
