An apparatus for removing harmful gas is provided to decrease the height of an absorption tower, thereby reducing size and weight of the apparatus, by forming a spiral flow of gas within an absorption tower so as to lengthen the path of gas. An absorption tower(10) has an upper face closed and a lower face opened. A gas inducing pipe(30) is connected to a lateral wall of the absorption tower so as to induce gas containing harmful gas within the absorption tower and form a spiral flow along an inner circumferential wall of the absorption tower. An absorption liquid jetting unit(40) jets an absorption liquid(4) to the gas induced within the absorption tower. A repair layer(15) for repairing the absorption liquid is positioned below an entrance of the gas inducing pipe within the absorption tower through a spiral flow forming space. The repair layer is installed so as to close an inner space of the absorption tower. A liquid receiving unit is installed below the repair layer to receive the absorption liquid dropped through the absorption layer. An exhaust path communicates with a lower portion of the repair layer. A gas inducing unit induces the gas containing harmful gas within the absorption tower from the gas inducing pipe to exhaust the gas from the exhaust path.
