METHOD AND APPARATUS FOR GAS EXCHANGE BETWEEN LIQUID AND GAS MEDIA Russian patent published in 1997 - IPC

FIELD: mass-exchange processes. SUBSTANCE: invention concerns a method of mass exchange between liquid and gas media by way of spraying liquid medium into forced gas medium stream as well as to apparatus related to the method, e.g. for wetting air or for treating flue gases. Method consists in that gas medium is passed through consecutively arranged, in direction of gas passage, narrowings and expansions of pathway thereby exerting velocity and pressure changes upon passing gas and spraying material being in contact with gas medium. Liquid medium is injected by means of at least one high- pressure nozzle into gas medium stream which has passed at least one narrowing. Apparatus is provided with deflectors installed in at least one part of flow channel and directed perpendicularly to flow channel axis. Outlet opening of nozzle is disposed in one part of flow channel, whereas the part accommodating deflectors has its beginning before outlet opening of high-pressure nozzle in stream direction. EFFECT: improved structure of apparatus and enhanced efficiency of process. 9 cl, 9 dwg
