FILM-FORMING DEVICE OF FILM APPARATUS TUBULAR ADAPTER Russian patent published in 2014 - IPC B01D3/28 B01D1/22 F28D3/04 

FIELD: process engineering.

SUBSTANCE: invention relates to hardware of heat exchange in gas-fluid system, particularly, to film heat exchangers and can be used for processing of heavy oil residues, for example, fuel oil. Proposed film-forming device is mounted at top section of pipes mounted at top and bottom tube plates. This device is composed of a bushing enveloping pipe end, its flow section increasing downward along pipe length. Cap enveloping bushing top part is arranged at film-forming device inlet and aligned therewith with clearance relative to tube plate. Holes are made on top side surface of said cap while at least two circular recesses are made at bushing top part.

EFFECT: higher efficiency of mass exchange.
