It travels in the form of an airflow, and presses heavy mist and dust against the outer wall side of the wind path by its centrifugal force, and can be separated from mist and dust having little or no mass. Mist dust can be dropped and collected as it is on the dust box side, and mist dust with little or no mass flows through the substantially S-shaped bypass flow path side. Separated and settled, dust The effect of the separation and collection makes it possible to increase the one-stage.

４Ｔに向けて進行させる。Since the pre-dust separator according to the present invention has the construction as described above, the stationary blade 3 as shown in FIG. 1 or the as shown in FIG. 2, FIG. 3 and FIG. Due to the supply from the tangential direction by the supply pipe 2K, the dust-containing air sucked and advanced into the substantially conical air path 4R or the narrow air path 4R 'while rotating in the circumferential direction is centrifuged. The heavy mist dust MR is separated by the swirling action on the outer wall side of the air passage 4R or 4R ', and is advanced toward the lower end port 4T along the outer wall without being subjected to the centrifugal turning action. The gas containing the mist dust ML having a small or no mass is made to advance toward the lower end port 4T while keeping the gas along the inner wall side of the air passage 4R or the outer surface of the inner cylindrical body 10.

Since the air flows as the shortest flow path and has the fastest flow velocity, only air that does not contain mist and dust that has proceeded while turning on the inner wall side of the air passage 4R passes through this portion and passes through the bypass passage 5T 'substantially in the S direction. Change the course and move forward, or
In FIG. 4, it descends at the interval 11 and then is sucked through the exhaust duct 7 to the dust collector side.
