Abstract
A cyclone separator, for the separation of particulate materials from a particle-bearing gas or vapour, in which the particle-bearing gas or vapour is injected into a separating chamber (10), and the particles centrifuged to a separating chamber wall (12) of the separating chamber (10) for collection, the separating chamber wall (12) being wetted by a liquid to assist in collection of the centrifuged particles from the separating chamber wall (12), the separating chamber wall being at least partly porous, the separating chamber wall (12) being wetted by the passage of the liquid through the porous part, to provide a more uniform wetting of the separating chamber wall (12), and hence more efficient particulate collection than previously achieved by prior art methods. The cyclone separator of the invention may also be used for the separation and collection of gas or vapour-borne vapours, in place of particulates.
