The present invention relates to an axial flow type dust collector and a pre-collecting device for an axial flow type dust collector. The present invention is to provide an axial flow type dust collector, capable of preventing the clogging due to dust of introduced dirty gas and increasing dust collection efficiency and operation rate, and a pre-collecting device for the axial flow type dust collector. To this end, the axial flow type dust collector according to the present invention comprises: a housing which has an inlet on one end thereof and an outlet on the other end thereof, forms a dust collection space inside, and includes a first outlet and a second outlet opened downward, and sequentially spaced apart from each other in a flow direction; a division part which is installed between the first outlet and the second outlet and divides the dust collection space into a front pretreatment part and a rear post-treatment part; a delivery pipe part which is concentrically disposed in the dust collection space so as to connect the pretreatment part and the post-treatment part; and a gas flow unit including a diffusing conical-shaped part, which is installed on the pretreatment part and diffuses the flow of dirty gas entering the inlet, and a converging conical-shaped part, which is installed on the downstream of the diffusing conical-shaped part and makes the flow of the dirty gas converge into the delivery pipe part. Therefore, the dust collector is capable of using only the pretreatment part detached from the axial flow type dust collector or using the axial flow type dust collector integrally, has low static pressure loss, is easily managed, and has high dust collection efficiency. |
