Abstract
A system for removing contaminants from a gas in an exhaust stack. A cone structure having a plurality of stacked cones is located in the exhaust stack in combination with a spray system including a water input pipe with a misting spray nozzle. Air or gas containing contaminants flows in the exhaust stack. The water from the nozzle system mixes with the air or gas to form a mist. The cones of the cone structure are stacked and held by rods to create slight changes in the flow direction of the mist. The flow of the gases drive the condensed liquid to the outside perimeter of the cones and to the inner wall of the stack or chimney where it is collected in a trough and removed.
