Description
Technical field
Technical field is utilized the invention belongs to desalinization and fume afterheat, is related to a kind of with flue gas reheat function
Power-plant flue gas waste heat direct-evaporation-type seawater desalination system.
Background technology
Shortage of water resources is the significant problem for being related to human survival and social development in world wide, with economic society of China
The fast development and the continuous propulsion of urbanization process of meeting, shortage of water resources have turned into the sustainable development of socio-economy of restriction China
Key factor.Desalinization is just increasingly paid attention to and developed as the effective means of water resources quantity is increased from source.Seawater
Desalination technology is greatly improved by development for many years.But desalting process ripe at present is also asked in the presence of some
Topic, on the one hand must all consume mass energy, the energy consumption cost of desalinization is direct determines using Re Fa or embrane method
The key factor of its application；On the other hand, to prevent fouling and corrosion, the highest evaporating temperature of low temperature multiple-effect distillation seawater
No more than 70 DEG C, and the low temperature multiple-effect distillation sea water desalting device heat source stream for depending on power plant is mainly derived from steam turbine the 4th
Section is drawn gas, for 600MW and above unit, and extraction temperature is higher than 320 DEG C, and parameter of drawing gas is far above required parameter, reduces vapour
Turbine does work, and also result in the waste of high-grade energy.
Coal-burning power plant can also produce substantial amounts of waste heat while energy generating is consumed.The heat energy that fire coal is produced, it is most of
In the form of exhaust steam in steam turbine, by condensation heat be cooled water take away, be discharged into environment, due to exhaust steam in steam turbine temperature compared with
Low, energy utilization value is little.And flue gas loss is maximum in boiler heat loss one.To ensure stable operation, power plant's pot
The exhaust gas temperature of stove is general between 120 DEG C~150 DEG C, and the heat for accounting for coal low heat value 8~12% scatters and disappears with smoke evacuation.Closely

Heat has been transferred in the flue gas after desulfurizing tower by the heat exchange of heat medium water.
Current fume afterheat desalinization, what is utilized is usually the waste heat of higher temperature flue gas.Generally indirect method, i.e.,
Produce hot water or steam first by high-temperature flue gas, be subsequently used for desalinization.The flue gas utilized is generally from internal combustion engine, because
This exhaust gas volumn is limited, and flue gas sea water desalinating unit scale is smaller, is mostly used for ship and offshore oil platform.Due to containing in flue gas
Some corrosive gas can condense precipitation when temperature is reduced, and dew point corrosion is caused in heat exchanging face, therefore lower temperature flue gas
Waste heat recovery has more difficulties.MGGH systems are operated under environmental condition of the cigarette temperature less than 150 DEG C, belong to cryogenic heat exchange equipment.
At present, the low-temperature corrosion of MGGH systems, dust stratification and abrasion the problems such as on have accumulated rich experience.These experiences are use
The direct desalinization of boiler of power plant fume afterheat, which is provided, uses for reference.
