Method of accelerating contact reactions in fluids and apparatus therefor

Abstract

In a method of operating such chemical and physical reactions as oxidation, reduction, absorption, mixing, heat exchanging, deodorizing of a fluid or fluids, an improved method of performing a multi-effect operation of any one of a combination of such chemical and physical reactions with a substantial acceleration effect comprising the steps of passing a fluid mixture of exhaust gases and an absorbent solution under appropriate pressure and flow velocity conditions through a flow deflecting member provided within a reacting area, thereby causing the fluid mixture to flow in an accelerated whirling flow state and to be split into concentrically dual layers of a generally liquid fluid and a generally gaseous fluid under effect of centrifugal force produced from the whirling motion of the fluids, and thereafter directing the dual fluid flows to collide against a plurality of projection members having a special cross-sectional shape, thereby causing the fluid mixture flow to be agitated violently and developing dispersion of fine particles of fluids within the reacting area. This finely dispersed state of the fluid mixture occurs efficiently at the moment of the collision action, splitting and rejoining with each other, resulting in remarkable improvement in the molecular motion within the boundary films of such dispersed fine particles of fluids and reduction of resistance of the boundary films thereof, and increase in a mass transfer rate thereof, whereby eventually there is attained an extraordinary contact efficiency between a gas and a liquid.
