Abstract
A hazardous gas abatement system decontaminates an exit gas stream containing global warming or contaminant gases using an electrical heater compartment and a water scrubber or dry chemicals in a tank. One or more top flow hazardous gas inlets introduce hazardous gases into a heater compartment. Air or oxygen is heated in a separate chamber surrounding the heater compartment. The heated streams are mixed and oxygen reacts with the hazardous gases. Solid particulates and heat are removed by a filter in a quick disconnect tank. Gas flows through an outer chamber insulated from surrounding the heater compartment and through water spray scrubbers or chemical agents. A heat exchanger surrounds the outer chamber. A moving cleaning ring cleans particles from the heater compartment. An air cylinder drives the cleaning ring up and down.
