ABSTRACT:
This pollution eliminator is comprised of three concentric vertical stacks or chimneys, wherein the outer stack is higher than the inner stack. Exhaust flue gases primarily from a furnace is directed up through the central stack, wherein the hot flue gases rise, as in a conventional chimney. The flue gases, on exiting the central stack, expand laterally wherein the fly ash is captured by the intermediate stack and drops down the annular space formed therebetween. The flue gases, on exiting this intermediate stack, further expand within the outer stack. Means are provided in the annular space between the outer and intermediate stack to cause water vapor to rise therein. The vapor reacts with some of the oxides of the gases from the flue to form acid molecules which are condensed on the upper inner wall of the outer stack. Means are provided, also in the outer stack, to cause the flue gases to spin, to enhance the capture of acid molecules on the wall thereof. To further enhance mixing of the flue gases with the water vapor, the intermediate stack has openings or apertures in its wall, primarily in the region above the center stack to allow water vapor to enter this stack.
