对提供液态添加剂的装置进行排空的方法
摘要：
本发明涉及一种用于使提供液态添加剂的装置(1)运行的方法，该装置带有用于输送液态添加剂的输送路径(2)，输送路径(2)具有至少一个第一区段(3)，在该第一区段中设有会被液态添加剂所沉淀出的沉积物(4)损坏的蠕动泵(24)，尤其是输送方向(5)可逆的蠕动泵，输送路径(2)还具有至少一个第二区段，在该第二区段中布置有对结冰敏感的部件(25)。在所述方法中，首先沿装置(1)的输送路径(2)输送液态添加剂。接下来停止添加剂输送。然后进行输送路径(2)的局部排空，其中在输送路径(2)的所述至少一个第一区段(3)中留有液态添加剂，而所述至少一个第二区段(26)则被排空。
摘要（英）：

The invention relates to a method for operating a device (1) for providing a liquid additive, comprising a conveying route (2) along which the liquid additive is conveyed, wherein the conveying route (2) comprises at least one first section (3), in which a peristaltic pump (24), in particular comprising a reversible conveying unit (5) is arranged, which unit can be damaged by deposits discharged from the liquid additive and the conveying route (2) furthermore comprises at least one second section (26), in which a freeze-sensitive component (25) is arranged. According to the invention at first liquid additive is conveyed along the conveying route (2) of the device. Subsequently, the conveying of liquid additive is stopped. The conveying route (2) is then partially emptied, wherein in the at least one section (3) of the conveying route (2) liquid additive remains, while the at least one second section (26) is emptied.
