Abstract

Es wird ein Verfahren zur Reinigung von pneumatischen Förderleitungen (2) mit einem Bypass-Molch (1) beschrieben, der druckluft-getrieben in der Förderleitung (2) längs bewegt wird und mit seinen am Außenumfang angeordneten Abreinigungswerkzeugen (18) die Innenwandung der Förderleitung (2) abreinigt, wobei die Druckluft durch in Längsrichtung angeordnete Öffnungen (14,15) den Molch (1) durchströmt und in Bewegungsrichtung nach vorne aus dem Molch (1) austritt und hierbei Feststoffe (z.B. ein Granulat (32)) von der Rohrwandung entfernt und mitnimmt. Um eine gute Abreinigungswirkung auch in mit Granulat (32) gefüllten Förderleitungen (2) zu erreichen, ist vorgesehen dass das Verhältnis von Molchgeschwindigkeit zu Förderluftgeschwindigkeit c/v kleiner 1 ist, und dass die Förderluftgeschwindigkeit geeignet ist, dass Granulat (32) in der Art einer Flugförderung zu bewegen.
