Title:
CYCLONE-TYPE FOREIGN MATTER SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2023/286419
Kind Code:
A1
Abstract:
Provided is a cyclone-type foreign matter separator affording a high defoaming effect that effectively suppresses foaming caused by bubbles in a processing fluid. A cyclone-type foreign matter separator 1 comprises: a cyclone body 2 equipped with a cylindrical section 2A and a conical cylindrical section 2B that extends downward, with a gradually decreasing diameter, from a lower end of the cylindrical section 2A; a processing fluid inlet pipe 3 equipped with an inlet port 3a that opens, in a tangential direction, into the cylindrical section 2A; an upper case 4 provided to the upper section of the cyclone body 2; a processing fluid discharge pipe 5 that is open to the upper case 4; a connecting pipe 6 that is arranged coaxially with the axial center O of the cyclone body 2 and that connects the interior of the cyclone body 2 to the interior of the upper case 4; and a defoaming pipe 7 which is porous, is arranged vertically inside an upper case 14 so as to be coaxial with the axial center O of the cyclone body 2, and has its lower end inserted into the connecting pipe 6. The cyclone-type foreign matter separator, wherein a vortex flow holding means (slit 14) for holding a vortex flow generated in the defoaming pipe 7 is provided to the defoaming pipe 7.
