Also, since flue-gas temperature is relatively high, contacted from after chimney discharge with the lower surrounding air of temperature, flue-gas temperature can continue
Decline, causes the water recovery Cheng Shui in flue gas.Condensing water droplet generates refraction, scattering to light, keeps plume white or grey
The condensed water that color causes visual pollution, and largely generates will cause precipitation, snowfall in being discharged into Atmospheric processes, influence part
Regional climate.
Currently, in wet desulfurizing process, in order to mitigate above-mentioned visual pollution and the influence to local regional climate, usually
Flue gas can be cooled down, to reduce the vapour content in flue gas.A kind of common type of cooling is in the prior art: setting
Then slurries after cooling are passed through desulfuration absorbing tower that is, by cooling down to the slurries of wet desulphurization by slurry heat exchanger
Spray tube layer in sprayed, with this achieve the purpose that reduce flue-gas temperature.
But found in practical application, when using the above-mentioned type of cooling, there are following two aspects drawbacks:
On the one hand be that slurry heat exchanger fouling, attrition and attack are serious, cause operation stability it is poor, safeguard operation cost
It is high；
It on the other hand is that water level frequently transfinites in desulfuration absorbing tower, the water balance of desulphurization system is destroyed, and it is de- to influence wet process
