Title:
CYCLONE SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/213242
Kind Code:
A1
Abstract:
The cyclone separation device comprises an inlet, a rotational flow generation unit, an outlet, and a discharge port. When the discharge port is placed at the lowest position with the central axis of a rotation chamber provided in a housing being horizontal, an air inflow control plate is disposed above the discharge port in a separation chamber. As seen from the front of the housing, the air inflow control plate is a plate with a through-hole side inclined downward. In addition, the separation chamber is an annular space straddling the four quadrants in the coordinate plane centered on the central axis. The through-holes are positioned in the second quadrant of the coordinate plane in the air flow rotational direction inside the rotation chamber. The separation chamber has a curved face along a space dividing plate in the third quadrant and the fourth quadrant of the coordinate plane and has two parallel planes on each coordinate plane axis in the first quadrant and the second quadrant.
