Abstract:
PCT No. PCT/GB96/00125 Sec. 371 Date Jul. 31, 1997 Sec. 102(e) Date Jul. 31, 1997 PCT Filed Jan. 23, 1996 PCT Pub. No. WO96/23590 PCT Pub. Date Aug. 8, 1996A liquid cleaning system, which includes a barrier type filter having a back-flush arrangement for recovering filter contaminants from the back-flushed liquid which is available only at a low, not necessarily consistent, rate, includes a fluid-powered centrifugal cleaner which, in addition to the normal shaft-mounted rotor through which liquid is passed to separate contaminants centrifugally due to rotor speed, includes fluid drive means in the form of fluid reaction drive nozzles supplied with pumped liquid from the system as a drive fluid to rotate the rotor at a speed above the minimum to effect centrifugal separation of the contaminants from the back-flushed liquid in the rotor and accumulation of the outlet of the rotor. The spent drive fluid mixes with the cleaned back-flushed liquid in a discharge region and both may be re-used in the system. The intermittently available cleaned liquid may emerge from the rotor by conventional fluid reaction nozzles and supplement the reaction of the drive nozzle means. Control valve means permits the rotor to be removed whilst liquid flows in the system.
