DEVICE AND APPLICATION METHOD FOR HEAT AND MASS EXCHANGE BETWEEN GAS AND LIQUID Russian patent published in 2018 - IPC B01D3/14 B01F3/04 B01J19/32 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to the chemical, metallurgical, energy and other spheres of industry and is associated with heat and mass exchange and chemical exchange, and interaction between two fluid media, such as gas and liquid, for example, for the gas dust and chemical contaminants removal. It can be used as scrubber, absorber, stripper, heat exchanger or chemical reactor. Fluid media mixing device includes upstream channel for the first fluid media, nozzles, forming the two-dimensional grate across this channel so that the first fluid medium passes through this grate, and means for the second fluid medium introduction into the channel above the grate. Plurality of nozzles have such shape and are located within this grate in such a way, that passing through this grate the first fluid media, was forming in the channel above this grid, at least by one stream of the first fluid medium for each of the plurality of nozzles. Each stream is formed by one of plurality of nozzles, is differently directed with at least one stream formed by the neighbouring nozzle. Plurality of streams are formed by nozzles so, that in the channel above the grate they form the first fluid medium nonlinear flow and in the channel above the grate interact with the introduced into this channel second fluid medium. Device implements the fluid media mixing method. Multiple fluid medium streams forming nozzle consists of housing with inlet and outlet openings, having side walls and central axis, and fixed inside this housing blades. Each blade has at least four edges. Each blade two adjacent edges are attached to the side wall, the other two adjacent edges are free. If you draw lines along the free edges, then these lines will surround the housing central axis.

EFFECT: technical result: high heat and mass transfer efficiency, high reliability.
