Cleaning gas flows through the granules falling down through the device against the direction of their fall. In the inlet area there is provided a guiding device (19) for the inflowing mixture (1) and a retention unit (2) for the larger particles (3). The distributing plate (6) is provided with a covering hood (16) having a recess (17) for the inflowing mixture. Between the distributing plate (6) and the covering hood (16) there is provided a slot (8), which preferably has a height of about 8 to 15 mm.
