NOZZLE MEMBER FOR MASS TRANSFER AND SEPARATION APPARATUSES Russian patent published in 1999 - IPC

FIELD: chemical mechanical engineering; may be used in the capacity of internal device in mass transfer and separation apparatuses for provision of phase contact and separation of dropping liquid from flow of gas (steam). SUBSTANCE: nozzle member has a set of parallel rods and plates with holes through which rods are passed and provided with plates which have additional holes to pass gas (steam) and partitions installed from atop and over the entire perimeter of plates for maintaining bubbling bed. Plates are installed at the height of nozzle member at some interval between one another, for instance, with cascade arrangement relative to one another. Plates are installed at an acute angle relative to rods. Installed in plate holes partially or in all holes are two or more rods of the same different diameters. Plates are made of cut-through drawn sheet. EFFECT: higher efficiency of contact and phase separation due to more rational organization of phase movement with formation of bubbling zones and more rational utilization of working area and volume of apparatus. 5 cl, 9 dwg
