Abstract:
1. An apparatus for removing a pollutant from a gaseous stream, comprising: a first vessel defining a first cavity; a second vessel adjoining said first vessel and defining a second cavity, said second vessel being of different dimensions from said first vessel, and said first and second cavities being combined to form a common chamber having an upper end and a floor; means for drawing a gaseous stream into said chamber at a first location and for drawing said gaseous stream out of said chamber at a second location; a plurality of partitions extending substantially from the upper end of said chamber to said floor, said partitions forming spaces therebetween; and a dry chemical medium disposed within said spaces between said partitions for neutralizing a pollutant in said gaseous stream; wherein said partitions have openings therein of a sufficiently large size to permit said gaseous stream to flow therethrough, and said openings being of a sufficiently small size to prevent said dry chemical medium from passing therethrough.
