Air pollution control apparatus and air pollution control method

摘要

An air pollution control apparatus according to an embodiment of the present invention includes: a stack (15) that discharges flue gas discharged from a boiler outside; a blower (13) that is provided downstream of the stack (15) and draws in the flue gas; and a CO 2 recovering apparatus (22) that recovers CO 2 in the flue gas drawn in by the blower (13). The stack (15) includes a controlling unit that suppresses release of the flue gas outside from the stack (15) and suppresses inflow of atmosphere to the stack (15), and the controlling unit is a channel forming unit (23A) that forms a serpentine channel through which the flue gas and the atmosphere in the stack (15) flow.
