Apparatus and method for withdrawing fluid from a zone

Means is provided for withdrawing fluid from a source in a body of fluid remote from the means of withdrawal by setting up a vortex (2, 31) extending from the withdrawal means (3, 22) to a structure (1, 32) bounding the fluid adjacent the zone from which fluid is to be withdrawn. The withdrawal mean...

Zusammenfassung:	Means is provided for withdrawing fluid from a source in a body of fluid remote from the means of withdrawal by setting up a vortex (2, 31) extending from the withdrawal means (3, 22) to a structure (1, 32) bounding the fluid adjacent the zone from which fluid is to be withdrawn. The withdrawal means includes a cylinder (7, 29) having an open end directed towards the withdrawal zone, means (11,30) for withdrawing fluid from the other end of the cylinder, and rotating elements (4, 26) within the open end of the cylinder to produce shear in the fluid. The fluid may be a gas or a liquid, and the vortex may be used to entrain fumes or particulate material to be withdrawn from the body of fluid. The means for withdrawing fluid may include means (9, 10) for withdrawing separate flows of fluid from the axial and peripheral portions of the vortex.
