System for scrubbing exhaust emissions

Abstract

A system for scrubbing chemicals and particulate matter from exhaust emissions using steam and water is provided. The system includes an exhaust pipe having an inlet and an outlet. The exhaust pipe is inclined by at least 2 degrees with respect to horizontal. Water and steam supply lines run parallel to the exhaust pipe and connect to a plurality of water and steam nozzles to inject water/steam into the exhaust pipe cocurrent to the direction of emissions flow. The nozzles are positioned along the length, and around the circumference, of the exhaust pipe to inject water/steam into the exhaust pipe from multiple directions to saturate at least a cross sectional area of the interior volume of the exhaust pipe with water/steam. Absorbed chemicals and particulate matter collect as wastewater at bottom of the exhaust pipe and drain by gravity into a reservoir positioned below the outlet.
