Abstract
The invention relates to a desalination process system utilizing waste heat. The system comprises a multi-effect evaporator, a heat exchanger, a pipeline, a desalination water pump, a water supply pump, a crystallization tank, a boiler, a desalination water tank and a circulating pump. Boiler flue gas waste heat or low-enthalpy-value steam pumped out from a low-pressure cylinder of a steam turbine is used as an energy source, and through the heat exchanger and the multi-effect evaporator, salt-containing water is changed into distilled water to realize a desalination purpose; the produced distilled water can be directly used as production water for a power plant or domestic water. According to the system, compared with the prior art, the electricity consumption, the occupied land size and the operation cost are greatly reduced, and secondary pollution caused by medicine utilization is avoided; the system is safe, simple, practical and reliable; by recycling flue gas exhaust heat discharged from the boiler or low-enthalpy-value steam pumped out from the steam turbine, the desalination process operation cost is greatly reduced, and a very high economic value is realized.
