FILM HEAT AND MASS TRANSFER APPARATUS Russian patent published in 2021 - IPC B01D3/28 

FIELD: heat and mass transfer technology and reactor devices.

SUBSTANCE: invention relates to heat and mass transfer technology and reactor devices and can be used in chemical and other industries for the implementation of various processes of physical and chemical interaction between gas and droplet liquid flows, in particular to a film heat and mass transfer apparatus. The apparatus consists of a housing with a bottom and a lid located inside the housing of the distributing pipe, a distribution device and a plane-parallel nozzle made of vertically arranged sheets with through flow channels between them. Wherein the plane-parallel nozzle is made with the formation of closed slotted cavities between adjacent vertical sheets, while the closed slotted cavities and through flow channels alternate with each other, and each of the closed slotted cavities is divided by a partition into interconnected parts and is connected by an inlet and outlet, respectively, to the inlet and outlet pipes for the coolant, where the distribution devices are formed by the upper and extension of the side walls of the closed slotted cavities.

EFFECT: invention increases efficiency of the apparatus and expands its functionality.
