Abstract

Zur Reinigung und/oder Trocknung der Innenwände bei verlegten Fernrohrleitungen wird innerhalb der Fernrohrlei­ tung der Druck abgesenkt und der durch Verdampfung der an der Rohrinnenwand haftenden Substanz gebildete Dampf und die gegebenenfalls vorhandenen Fremdgase aus der Fernrohrleitung abgesaugt. Das abgesaugte Medium pas­ siert nach Verlassen der Fernrohrleitung und vor Eintritt in die Absaugeinrichtung einen Kondensationsapparat, dessen Kühlflächen auf einer tieferen Temperatur als die Rohrwand­ temperatur gehalten werden. Bei einer ausreichenden Tem­ peraturdifferenz, um den Substanzdampf an diesen Kühlflä­ chen niederzuschlagen, konnte die Trocknungsleistung ge­ genüber einer reinen Vakuumtrocknung wesentlich gestei­ gert werden. For cleaning and / or drying the inner walls at Telescopes are laid within the telescope device the pressure is reduced and that by evaporation of the Vapor formed on the inside of the tube and any foreign gases from the Telescope suctioned off. The aspirated medium pas after leaving the telescope and before entering the suction device a condenser whose Cooling surfaces at a lower temperature than the pipe wall temperature are maintained. With a sufficient tem temperature difference to the substance vapor at this cooling surface drying, the drying performance could be reduced significantly increased compared to pure vacuum drying be tied.
