INSTRUMENT FOR INJECTING FLUID INTO APPARATUS, PARTICULARLY COLUMN

PROBLEM TO BE SOLVED: To provide a fluid introduction injection capable of constituting a structure which is stable at elevated temperatures. SOLUTION: A fluid injection instrument (1) is provided on an apparatus (10), particularly a column (10'). Inflow protrusions (2) present on a wall (11) in the apparatus functions to feed a fluid which may be a single phase or multiphase. The distribution chamber (3) is located adjacent to the downstream side of the inflow protrusions. A guide lamella (4) is disposed on at least one release side of this chamber, whereby a fluid (2a) fed into the apparatus can be distributed on the surface of the apparatus and can be guided on a curved path. In the case of a dual-phase fluid, a dispersed phase having a higher density can be at least partially separated simultaneously with distribution by taking advantage of centrifugal force. Wall panels (5, 6) on closed side of the distribution chamber, particularly a base panel and a top panel, together with the guide lamella fixed to them, constitute a structure in a stable shape. All the guide lamellae are connected to a wall panel at its side edge through a stopper joint which provides connection compatible with the shape. The stability of the structure is established by fixation to one or all stopper connection parts by an additional connection means. COPYRIGHT: (C)2006,JPO&NCIPI
