Abstract

Verfahren und Vorrichtung zur Trocknung von entzündlichem Trocknungsgut in einem Trockner (3), bei dem ein Trocknungsgas, vorzugsweise Trocknungsluft, mithilfe einer Heizeinrichtung (9) erhitzt und dem Trockner (3) zugeführt wird, wobei das Trocknungsgas nach Verlassen des Trockners (3) in eine Kühleinrichtung (21), in dem das Trocknungsgas in Wärmeaustausch mit einem Kühlmedium, vorzugsweise Kühlwasser, steht, eingeleitet und über einen geschlossenen Leitungskreislauf (34, 14, 19, 28) in die Heizeinrichtung (9) rückgeführt wird. Das Kühlmedium in der Kühleinrichtung (21) durchläuft hierbei einen geschlossenen Kreislauf, wobei eine Regelung der Temperatur des Kühlmediums ab einer Temperatur des Trocknungsgases von etwa 80°C erfolgt.

Method and device for drying flammable drying material in a dryer (3), in which a drying gas, preferably drying air, heated by a heater (9) and the dryer (3) is fed, wherein the drying gas after leaving the dryer (3) in a cooling device (21) in which the drying gas is in heat exchange with a cooling medium, preferably cooling water, is introduced and recycled via a closed line circuit (34, 14, 19, 28) in the heating device (9). The cooling medium in the cooling device (21) in this case passes through a closed circuit, wherein a control of the temperature of the cooling medium from a temperature of the drying gas of about 80 ° C takes place.
