Abstract
Abstract A device for replacing common smoke stacks on industrial building roofs. This device includes a multiple number of pollution sensing devices on the interior of a chamber which contains a multiple number of spray nozzles which produce a high pressure fog. The chamber also includes a catch basin which allows the fluid to drain off into the sump.

An anti-pollution chamber, comprising in combination, a conical configurated hollow main body, support means carried by said chamber for holding it rigidly to a roof of a building, elbow means carried by said chamber for introducing the smoke into said main body, a plurality of high pressure fog producing nozzles carried by said body for 100 percent saturation of the interior of said main body, pollution sensing devices carried on the interior of said chamber for indicating the degree of pollution of the smoke introduced therein, a baffle containing stack means carried by said chamber for letting off the purified air, a catch basin carried by said stack means providing a drain off of the pollutant in order to return the same to sumps at a lower level, said smoke entering through said elbow of said main body at a smaller end of a chamber thereof, and a high pressure water line being provided with a plurality of spaced apart nozzles on the interior of said main body, said nozzles producing said fog so to remove the solid particles and to change a gas into a purer state, said conical chamber of said main body and the position of said high pressure nozzles tending to move particles laden smoke in a circular motion toward a point of exit to the outside atmosphere, the criticality of the circular motion of pollution laden smoke being intended to retard the flow of the vapors only so long as to extract particles there from, said stack means comprising a stack of short length and provided with said baffle, said baffle being positioned angularly upwards and being of a number as necessary to restrict the uptake until the pollutants are reduced to nearly zero when the output passes through said stack and catch basin at the lower portion of the larger diameter area of said main body receiving the solid pollutants, water and chemicals, and allow them to be carried down the return line to said sumps within said building wherein filtering takes place and the water and chemicals are recycled by pumping means through the lines having said nozzles, said catch basin of said chamber being positioned beneath said stack at the large diameter end of said main body and being fed the solid pollutants and water by gravity means due to the axis of said main body being substantially parallel with a roof top of said building.
