Description

Technical Field

[0001] The utility model relates to the technical field of heating desalted water, in particular to a desalted water step heating device. Background Art

[0002] Refers to the finished water obtained by removing suspended matter, colloids, inorganic cations, anions and other impurities in water through various water treatment processes. Waste heat is the energy that is not utilized in energy utilization equipment under certain economic and technical conditions, that is, redundant and waste energy. Waste heat recovery is an important way to improve economy and save fuel.

[0003] The patent with publication number CN 208154454 U discloses a waste heat power generation desalted water deoxygenation system, which includes a desalted water tank, a desalted water pump, a deaerator, a feed water pump, and a waste heat boiler connected in sequence by pipelines, and also includes a desalted water heating device, and the desalted water heating device includes a heat exchanger. The device realizes secondary waste heat utilization of the high-temperature flue gas of the calcining furnace after cooling by the waste heat boiler, reduces resource waste, protects the environment, and has good economic and social benefits. However, the device has the problem that the high-temperature flue gas discharged from the calcining furnace through the waste heat boiler is introduced into the heat exchanger to heat the desalted water and then discharge the flue gas. However, when this device system is used, the high-temperature flue gas is discharged by a fan after passing through the heat exchanger only once. At this time, the flue gas should still have a certain temperature, and it is too wasteful to discharge it directly from the chimney. For this reason, a desalted water step heating device is proposed to solve the problem that the existing desalted water step heating device cannot fully utilize the heat of the high-temperature flue gas.
