Abstract
An apparatus for removing dust from hot gas under pressure comprises a housing for filter units disposed in cascade between an upper inlet and a dust funnel at a lower part of the housing. Each filter unit comprises a grate array of collecting ducts to which rigid filter candles of porous ceramic tubes are connected. Clean-gas pipes communicate with the ducts and extend within the housing to a clean-gas chamber at which they open through nozzles juxtaposed with drive gas pipes capable of propelling gas through the clean-gas pipes for dislodging deposits of the filter candles.
