Description
Technical field
The present invention relates to a kind of thermal power plant minimum discharge MGGH (intermediate heat media flue gas heat-exchange unit: Media Gas-
GasHeater) energy-saving environmental protection device and method, belongs to thermal power plant's minimum discharge MGGH technical field.
Background technology
The minimum discharge problem of coal-fired plant boiler smoke evacuation has obtained country's attention, in developed area such as
The place such as the Yangtze River Delta, Zhujiang River triangle emits white cigarette to chimney and the most quite payes attention to.The leakage of the GGH system owing to using in the past causes
It is unable to reach minimum discharge, so the application of MGGH is more and more universal.
Flue gas desulfurization (Fluegasdesulfurization is called for short FGD).The lime-gypsum stone wet method cigarette of coal-fired flue-gas
Desulfurization technology is the desulfurization technology that current application is the widest, efficiency is the highest.For coal-burning power plant, considerably long in modern later
In period, FGD will be the main method controlling SO2 discharge.Flue gas desulfurization mainly has dry type flue gas desulfurizing and wet process of FGD
Two kinds.Wherein wet fuel gas desulfurizing technology flow process, form and mechanism are similar, mainly use limestone (CaCO3), Calx
(CaO) or the serosity such as sodium carbonate (Na2CO3) makees detergent, in reaction tower, flue gas is washed, thus remove in flue gas
SO2.This technique history of existing 50 years, after continuously improving and improving, Technical comparing is ripe, and has desulfurization effect
Rate high (90%~98%), unit capacity is big, and coal adaptability is strong, and operating cost is relatively low and the advantage such as side-product easily recovery.Also
Wet desulfurizing process just so that flue gas after desulfurization water capacity increases, these with saturated wet flue gas state from desulfurizing tower discharge into
Enter chimney and arrange the flue gas to air, cause grand chimney and emit white cigarette phenomenon.
Since saturated wet flue gas state can emit white cigarette from chimney discharge, then heating neat stress disengages it from saturation again
Discharge just can alleviate and emit white cigarette phenomenon, thus utilize the neat stress after the heating desulfurizing tower of the flue gas heat before desulfurizing tower, MGGH skill
Extensively arising at the historic moment of art.After solving the key technical problem of flue gas low-temperature corrosion, the economy of MGGH system seems
Important, how on the premise of reaching neat stress emission request, improve benefit of saving coal as far as possible and become as vast electric power skill
The target that art worker pursues
Existing MGGH (tubular type flue gas heat-exchange unit, hydrophily formula flue gas heat-exchange unit, tubular type GGH) system, uses auxiliary in winter to steam
The mode of vapour heating regulates flue-gas temperature, and whole system is when summer condition runs, and substantial amounts of smoke discharging residual heat enters with heat medium water
Desulfurization fume exhaust, the waste that assembly is meaningless.Meanwhile, before lacking regulation cleaner unit summer, gas cooler exports the means of cigarette temperature, presses
Heat exchange area bigger than normal need to be designed according to existing design with summer condition gas cooler, cause the waste of metal material, in the winter time
Under operating mode and be not suitable with.Meanwhile, need to control well the inlet flue gas temperature of cleaner unit, for electric dust collector, reduce flue-gas temperature, subtract
Lack flue gas volume flow, reduced the ratio resistance of dust, improve efficiency of dust collection, reduce dedusting power consumption.Cloth bag is removed
Dirt device, controls flue-gas temperature, prevents overtemperature flue gas from entering, it is ensured that the safety of device and reduce dedusting power consumption.Mesh
It is poor that front MGGH system adapts to seasonal variations ability to work.
