Air pollution control system and method
View Patent ↗SO x removal equipment for reducing sulfur oxides from flue gas from a boiler, a cooler which is provided on the downstream side of the SO x removal equipment, for reducing the sulfur oxides from the flue gas and for decreasing a gas temperature, CO 2 recovery equipment including: an absorber for bringing CO 2 in the flue gas into contact with a CO 2 absorption liquid so as to be reduced; and a regenerator for causing the CO 2 absorption liquid to emit CO 2 so as to recover CO 2 and regenerate the CO 2 absorption liquid, and a wet type electric dust collector for reducing a mist generation material which is a generation source of mist that is generated in the absorber of the CO 2 recovery equipment before introducing the flue gas to the CO 2 recovery equipment, are included.
1. An air pollution control system comprising:
SO x removal equipment for reducing sulfur oxides from flue gas from a boiler;
a cooler which is provided on a downstream side of the SO x removal equipment, for reducing the sulfur oxides that remain in the flue gas and for decreasing a gas temperature;
CO 2 recovery equipment including:
an absorber for bringing CO 2 in the flue gas into contact with a CO 2 absorption liquid so as to be reduced; and a regenerator for causing the CO 2 absorption liquid to emit CO 2 so as to recover CO 2 and regenerate the CO 2 absorption liquid; and
a wet type electric dust collector for reducing a mist generation material which is a generation source of mist that is generated in the absorber of the CO 2 recovery equipment before introducing the flue gas to the CO 2 recovery equipment.
2. The air pollution control system according to claim 1 , further comprising:
NO x removal equipment for reducing nitrogen oxides from the flue gas; and
a dry type electric dust collector for reducing particulates.
3. The air pollution control system according to claim 1 ,
wherein a SO x removal unit is provided to be integrated into the cooler, and a wet type electric dust collection unit is provided on a downstream side of the SO x removal unit.
4. An air pollution control method comprising:
on an upstream side of CO 2 recovery equipment for bringing CO 2 in flue gas into contact with a CO 2 absorption liquid so as to be absorbed and reduced,
on a downstream side of SO x removal equipment, reducing particulates and mist from the flue gas by a wet type electric dust collector; and
decreasing an amount of mist generation material in the flue gas introduced to the CO 2 recovery equipment to a predetermined amount or less.
5. The air pollution control method according to claim 4 ,
wherein a SO x removal unit and a wet type electric dust collection unit are included in a cooler to perform SO x removal and reduce particulates and mist.
