Abstract
Apparatus and a method for handling a gas and a liquid in a manner to cause a specific interaction between them. The gas is placed into circulation to cause it to make a liquid circulate in a vortex fashion to present a liquid curtain. The gas is then passed through the liquid curtain by angled vanes to cause the interaction between the two fluids, such as the heating of the liquid, scrubbing of the gas, adding a chemical to the liquid and the like. The vanes are spaced apart and project inwardly from the inner periphery of an annular support so that the circulating liquid readily moves into the spaces between the vanes to create the liquid curtain. A number of embodiments of the invention are disclosed.
Claims22
Apparatus for creating an interaction between a gas and a liquid comprising:
- a housing having a gas inlet, a gas outlet and means defining a circular path of travel for a gas between the inlet and outlet, said housing further having a pair of vertically spaced members, the lower member having an annular portion defining a generally continuous inner periphery, there being structure coupled to and extending downwardly from said lower member, and a plurality of spaced vanes mounted in fixed positions within the housing between said members, each of said vanes projecting inwardly of said inner periphery of the lower member, said vanes being at acute angles relative to each other and arranged in a circular pattern in surrounding relationship to a central, liquid-receiving space in the housing, the central space communicating with the outlet, the spaces between the vanes defining fluid passages in flow communication with said central space and in fluid communication with said path and extending substantially along said path, there being means coupled with the housing for introducing a liquid thereinto, whereby a gas flowing through said fluid passages and into said central space will create a vortex action in the latter to cause a liquid therein to move upwardly with respect to said structure past said inner periphery and to enter said fluid passages to thereby form a penetrable liquid curtain extending across the fluid passages for contact with the gas as it flows from said path into said central space.
A method of creating an interaction between a gas and a liquid comprising:
- providing a circular fluid flow path in surrounding relationship to an open central space;
- providing a generally continuous inner peripheral opening between the path and the central space;
- forming a number of spaced fluid passages near the inner periphery of the path with the fluid passages projecting inwardly of said inner peripheral opening and communicating with said path, said central space and a region below said opening;
- moving a gas along said path, said fluid passages extending at acute angles to the direction of travel of the gas to thereby permit portions of the gas to enter said central space through said fluid passages and to create and maintain a vortex action therewithin adjacent to the inner ends of said fluid passages;
- forming and maintaining a penetrable liquid curtain extending upwardly from said region and across the inner ends of said fluid passages in response to said vortex action;
- directing the gas through said liquid curtain and into said central space;
- and allowing the gas to move out of said central space.
