Title:
SEPARATION DISC STACK
Document Type and Number:
WIPO Patent Application WO/2017/203565
Kind Code:
A1
Abstract:
The present invention is a separation disc group 61 obtained by forming, on first separation discs 63A, ribs 63a that extend radially from the center of rotation in a first direction that is slanted in one direction of the direction of rotation and forming, on second separation discs 63B, ribs 63b that extend in a second direction that is slanted in the opposite direction of the direction of rotation from the one direction, and stacking said first and second separation discs 63A and 63B alternately in the axial direction of a spindle 52, wherein the ribs 63a and ribs 63b that are adjacent to each other can be stacked vertically so as to intersect in at least one place, thereby increasing rigidity in the vertical direction during rotation, and balancing the stacked separation discs 63 as a whole. Since it is also possible to maintain uniform clearances between the separation discs 63A and 63B that are adjacent to each other in the vertical direction, it is possible to prevent reduction in separation efficiency and to limit the resistance applied on the gas flow.
