Ratio≤1:2 of flue gas flow is discharged into atmosphere after being sufficiently mixed later by the flue gas mixing arrangement on chimney outer cylinder top, real
Existing flue gas takes off white.
The utility model has the beneficial effects that
1, the flue gas after the suitable semi-dry process flue gas desulphurization system of the utility model takes off white, after can effectively solve semi-dry desulphurization
White cigarette problem of the flue gas in autumn and winter is invested low compared with other methods with operating cost.Operating cost is compared with prior art decline about 30%
Left and right.
2, chimney is designed using inner/outer tube, effectively solves the problems, such as environment monitoring；Chimney height is reduced simultaneously, city can be improved
The skyline on area periphery.
3, mix and conditioner and air heating apparatus be set at air port, by adjust air capacity and air themperature come
It is white to realize that the flue gas under different temperatures takes off.
Detailed description of the invention
Fig. 1 is the schematic diagram for taking off white device for being suitble to semi-dry process flue gas desulphurization system.
Wherein, 1 is chimney outer cylinder, and 2 be chimney internal cylinder, and 3 be gas inlet flue, and 4 be CEMS system, and 5 be to mix air port, 6
It is air heating apparatus for conditioner, 7,8 be flue gas mixing arrangement, and 9 be air preheater hot blast conveying pipe road.
