Abstract

Gaseous fluid dust separator apparatus comprising a porous layer separating a powder fluid intake chamber from a purified fluid collection chamber, and a gas intake duct for countercurrent cleaning of the porous layer, comprising a shut-off valve intended to put said duct, at the moment of its opening, in communication with the collection chamber and to isolate this chamber from the outside, characterized in that it includes, in the collection chamber, the purified fluid, wave emission means voices towards said porous layer intended to reinforce the action of the cleaning countercurrent.
