Abstract

Cyclonic separating apparatus comprising a cyclone (114) for effecting cyclonic separation and a tangential inlet for supplying fluid to the cyclone (114), the tangential inlet having at least two points of entry (152) into the interior of the cyclone (114). Each point of entry consists of a longitudinal slot (152) located in the cyclone for directing fluid into the cyclone in a tangential manner and each slot has a vane (154) for directing fluid through the respective slot. Providing two or more points of entry (152) to the interior of the cyclone (114) effectively spreads the inlet over a greater proportion of the circumference of the cyclone (114). The dimensions of the apparatus (110) can therefore be reduced and, furthermore, losses due to friction can be minimised. <IMAGE>
