Air pollution control apparatus and air pollution control method
View Patent ↗An air pollution control apparatus according to an embodiment of the present invention includes: a stack that discharges flue gas discharged from a boiler outside; a blower that is provided downstream of the stack and draws in the flue gas; and a CO 2 recovering apparatus that recovers CO 2 in the flue gas drawn in by the blower. The stack includes a controlling unit that suppresses release of the flue gas outside from the stack and suppresses inflow of atmosphere to the stack, and the controlling unit is a channel forming unit that forms a serpentine channel through which the flue gas and the atmosphere in the stack flow.
1. An air pollution control apparatus comprising: a stack that discharges flue gas, discharged from an industrial facility, outside; a blower that is provided downstream of the stack and draws in the flue gas; and a CO 2 recovering apparatus that recovers CO 2 in the flue gas drawn in by the blower, wherein the stack includes a controlling unit that suppresses release of the flue gas outside from the stack and suppresses inflow of atmosphere to the stack, and the controlling unit is a static mixer that mixes the flue gas and the atmosphere.
2. The air pollution control apparatus according to claim 1 , further comprising a flue gas return flow channel that returns, into the stack, a part of the flue gas fed to the CO 2 recovering apparatus by the blower.
3. An air pollution control method using the air pollution control apparatus according to claim 1 , comprising using a density difference between flue gas discharged from the industrial facility and atmosphere flowing in from outside of the stack, the density difference being caused by a temperature difference therebetween, to prevent the flue gas from flowing outside.
4. An air pollution control method using the air pollution control apparatus according to claim 1 , comprising mixing flue gas discharged from the industrial facility and atmosphere flowing in from outside of the stack to prevent the atmosphere from flowing further inside of the stack.
5. An air pollution control method according to claim 4 , comprising using the air pollution control apparatus to prevent the flue gas from flowing outside of the stack.
