<p>The invention provides a liquid distribution device for use in, for example, extraction beds. The device comprises an elongate chamber or hollow arm 5 defined by two plates 1 and 2, a cylinder 9 closed at one end by a wall 11 and opening at the other end into the chamber 5 through one of the plates 1 and a pipe 12 opening tangentially into the cylinder 9. Liquid enters the cylinder 9 through the pipe, and flows around the side wall 10 of the cylinder and impinges upon the opposed plate 2 of the chamber, where it is spread along the plate 2 and leaves through the slot 8 between inclined portions 6 and 7 of the plates.</p> |
