ABSTRACT:
In an arrangment for removal of precipitation from the vertical inner wall 1 of a tank having a floating roof, a water stripping element 2 is provided which interrupts the water film 6, running down the inner wall, absorbs the water and removes it at a suitable point. For this purpose, the stripping element 2 consists of a layered unit of elastic materials which are constructed in the vertical direction alternately of water absorbing and water permeable layers 3 and of water impermeable layers 4. The upper and the lower layers consist of water impermeable layers. The unit forms in the cross-section a rhomboid so that the individual layers 3, 4 are pressed at an acute angle towards the tank wall and each individual layer comes with its end face in full contact with the tank wall. The stripping element is combined of individual pieces to a closed ring which is held by the receiving elements and is pressed against the tank wall by spring elements.
