Abstract
A scrubber for exhaust gas cleaning onboard a marine vessel, comprising a scrubber shell (12) forming a scrubber chamber; and a tubular pipe (18) running through the scrubber shell for feeding scrubber liquid into the scrubber chamber; a concave bowl (32) for connecting the tubular pipe to the scrubber shell, the concave bowl having the shape of a solid of revolution, and the shape curving smoothly from the rim (46) of the concave bowl to the bottom (48) of the concave bowl. The tubular pipe runs through the bottom of the concave bowl in such a way that the bottom encircles the tubular pipe, and the tubular pipe and the bottom are connected to each other. The concave bowl is placed in an opening (34) in the scrubber shell in such a way that the scrubber shell encircles the rim of the concave bowl, and the scrubber shell and the rim are connected to each other.
