Abstract
A rotary valve regenerative oxidizer generally includes a combustion chamber communicating with a first end of plurality of pie shaped heat exchange chambers and a rotary valve communicating with a second end of the heat exchange chambers. A contaminated gas is directed through an inlet of the rotary valve, through a first group of heat exchange chambers, and into the combustion chamber thereby heating and purifying the gas. The heated and purified gas is directed from the combustion chamber through a second group of heat exchange chambers and through an outlet of the rotary valve. A portion of the heated and purified gas received from the outlet of the rotary valve is directed through a heating element 56 for heating the gas to a temperature sufficient to volatilize organic solids for purging a third group of heat exchange chambers. The gas is directed from the third group of heat exchange chambers into the combustion chamber and out of the oxidizer through the second group of heat exchange chambers.
