ABSTRACT:
A filter apparatus and filtering system which is particularly applicable for extracting particulated material from hot gases comprising a collector overlying a portion of the upstream face of the filter element for applying a reduced pressure to the particulate filter cake formed thereover to effect a dislodgement and recovery of the filtered particulate material. The collector is movable to progressively traverse substantially the entire upstream face of the filter element to effect a cleaning thereof by removal of the filter cake without interruption of the operation of the filtering system. The invention further encompasses a separator for cleaning the granular filter medium withdrawn from the filter apparatus and for recycling the cleaned filter medium back to the filter apparatus.
