Abstract
1. Process for the regenerative purification of a filter medium in granulate form charged with impurities which forms a filter bed (F) between the gas-permeable walls (W1, W2) of a vertically positioned filter element and which is sucked upwards at least partially during a regeneration phase from the lower area of the filter element into a lower inlet opening (5a) of a conveying tube (5) arranged in the centre of the filter element and is sucked upwards in this conveying tube and fed into a separation process taking place above the filter element in a separating apparatus (1, 53, 54, 29), in which the impurities are separated from the filter medium and the purified filter medium is fed back into the filter bed in the upper region of the filter element, characterized by regulation of the quantity of granular filter medium fed into the lower inlet opening 5 a of the conveying tube in the lower region of the filter element so that the upper limit of the portion of the filter medium arriving in the vicinity of the inlet opening (5a) of the conveying tube is below the lower edge of this inlet opening and a fluidised zone is formed from the said portion of the filter medium in the vicinity of the lower inlet opening (5a) of the conveying tube, using the suction in the conveying tube (5) as well as a supply of cleaning or flushing gas into this protion of the filter medium from an area above the inlet opening of the conveying tube.
