Abstract

The invention discloses a sea water desalination system based on steam trapping and waste heat recovery for flue gas from a power plant. A boiler is connected with a dust catcher, shell pass of a first steam absorber, shell pass of a flue gas waste heat recoverer, an induced draft fan, a desulfurizer, shell pass of a second steam absorber, a booster fan and a chimney through a pipeline; low-temperature fresh water is heated by the second steam absorber and the first steam absorber, enters a flash evaporator and flashes in the flash evaporator to produce steam which serves as heating steam of afirst-effect evaporator of the sea water desalination device; part of cooling drained water of a condenser passes through a concentrated water heat recoverer, a fresh water heat recoverer and a fluegas waste heat recoverer, after heat recovery, the water serves as a fed material to enter multiple effect evaporators. The sea water desalination system has the advantages that steam in the flue gascan be trapped, flue gas corrosion can be reduced, water consumption of the desulfurizer can be reduced, and sea water desalination can be realized by waste heat.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination and water vapor capture in flue gas and waste heat utilization, and more specifically relates to a seawater desalination system based on water vapor capture and waste heat recovery in power plant flue gas. Background technique [0002] my country has a large population, and the per capita water resources are seriously insufficient. The shortage of water resources has become an important factor restricting the sustainable development of my country's economy and society. Seawater desalination is an important means to increase the amount of water resources from the source and ensure water security, and it is being increasingly valued and developed. Through years of research, the relatively mature technologies for seawater desalination in my country include low-temperature multi-effect distillation and reverse osmosis seawater desalination. Low-temperature multi-effect distillation requ...
