FOREIGN MATTER REMOVAL DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/013885

Kind Code:

A1

Abstract:

In a foreign matter removal device (1) that removes foreign matter contained in a fluid within piping by using a swirling flow generated within a trap section (2), the fluid is caused to flow into the trap section (2) and is separated into an inner fluid that flows inside a separation section (5) and an outer fluid that flows outside the separation section (5). First foreign matter, which has a higher specific gravity than the fluid contained in the outer fluid, is captured in a gap between the inner wall of the trap section (2) and the separation section (5), and second foreign matter, which has a lower specific gravity than the fluid contained in the inner fluid, is discharged to the outside from a foreign matter discharging means (8) via a foreign matter discharging means connection part (9) provided to the ceiling of the trap section (2) at a location vertically above the center of the trap section (2), separation of the second foreign matter being promoted by a gas-liquid separation unit (11).
