Title:
SECONDARY FLOW FORMATION DEVICE, SOLID-LIQUID SEPARATION DEVICE, AND SOLID-LIQUID SEPARATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/243448
Kind Code:
A1
Abstract:
A secondary flow formation device (1) causes a fluid having solid particles dispersed therein to flow through a flow passage (7) and forms a secondary flow of the fluid in the transverse-section direction, the secondary flow formation device comprising a flow passage part (2) that includes the flow passage (7), and a plurality of baffle plates (5) that are formed at the flow passage part (2). The flow passage (7) has a rectangular transverse section such that an aspect ratio (AR), which is a flow passage width (w) divided by a flow passage height (h), is within a range of 3-100. Inner walls forming the flow passage (7) include a top wall (3a) as a first wall and a bottom wall (4c) as a second wall, which are oriented toward each other in the direction in which the flow passage height (h) is defined. The plurality of baffle plates (5) each have a rod-shaped part disposed to the second wall so as to protrude toward the first wall. The extension direction of the baffle plates (5) is parallel to the second wall and is inclined at a fixed inclined angle with respect to the extension direction of the flow passage (7).
