Description
Technical field
The present invention relates to flue gas desulfurization application field more particularly to a kind of smoke processing system and methods.
Background technology
It is promulgated with national environmental protection portion《Fossil-fuel power plant atmospheric pollutant emission standard》(GB13226-2011) reality
It applies, it is desirable that coal-burning boiler dust emission standard reaches 30mg/Nm3, SO2 contents, which are distinguished to control by newly-built and existing power plant, to exist
100mg/m3、200mg/m3, key area flue dust and SO2 discharge capacitys are controlled in 20mg/m from now on3、50mg/m3.It is increasingly stringenter
Atmosphere pollutants emission standards, force coal-burning power plant and other coal-burning boiler enterprises to need to change flue gas emission
It makes, to meet ultra-clean emission request.Currently, coal-burning boiler generally uses Gypsum Wet technology to carry out at flue gas desulfurization
Reason.
Since the flue-gas temperature after use Gypsum Wet technology desulfurization is low and is substantially at saturation state, exist
Problems with：
(1) on the one hand since exhaust gas temperature is low, sulfur dioxide, sulfur trioxide in flue gas are formed with the condensed water of precipitation
Sulfuric acid and sulfurous acid generate corrosion to flue and chimney.
(2) desulfurization fume outlet water capacity is big, lies substantially in saturation state, and carry gypsum particle secretly, in discharge process,
Flue-gas temperature reduces, and the elutriation in flue gas goes out, and phenomena such as chimney periphery forms " gypsum rain ", " white haze ", causes unnecessary
Economic loss and environmental problem.

Sulfur content, it is synchronous to reduce desulfurization slurry consumption, and then the water capacity of flue gas is reduced in reduction flue gas while slurries entrainment；
By the energy heats neat stress of former flue gas, ensure that exhaust gas temperature on dew point, reduces the humidity of flue gas, mitigate to flue and
The corrosion of chimney improves the rising height of discharge flue gas, realizes ultra-clean discharge truly, eliminates " white haze ", " gypsum
The problems such as rain "；By using the gas-gas heat exchanger of straight passage structures, existing flue gas heat-exchange unit blockage problem is solved, is realized simultaneously
It is transformed using original flue system, improvement expenses is greatly reduced.
