FLUID SPRAYING APPARATUS

摘要

A fluid spraying apparatus (10) comprising a generally cylindrical body defining a longitudinal axis, which body comprises: a first fixed part (12) comprising inlet means (16) adapted for connection to a pumped supply of fluid, and turbine means (40, 42, 44) arranged to be driven by said fluid; and a second rotatable part (14) comprising gear means (46-60), and one or more nozzles (82) in fluid communication with the turbine means for outletting the fluid as one or more jets, which nozzles extend radially of the longitudinal axis, which rotatable part is drivable by the turbine means through said gear means such that said nozzles are caused to rotate about said longitudinal axis; characterised in that none of the nozzles extends radially of the longitudinal axis further than the body. The apparatus is adapted to operate at a working pressure of 4-8 bar to provide a flow-rate of 400-700 m<3>/hr, and is thus suitable for use with low pressure pumps of the kind often found at oil refineries.
