Abstract
Process to ascertain combustion and/or decomposition of gaseous and/or by air or other gas carried particulate pollutants. The invention makes possible an effective and safe combustion and/or decomposition of pollutants not desired to escape into the environment. The pollutants are fed into a combustor (1) in which the pollutants are self combusted and/or are made to self decompose, whereby in the combustor outgoing gas is made to heat ingoing gas and/or by air or other gas carried particulate pollutants through counter current regenerative heat exchange. The invention also refers to an equipment for accomplishment of the process.
Claims13
A process for treatment of gas, vapor, or air-borne particulant pollutants comprising the steps of:
- feeding the pollutant gas into a chamber having a heated bed with heat-accumulating and heat-exchanging properties, to raise the termperature of the pollutant gas to cause combustion or decomposition thereof;
- and
- reversing the direction of gas flow in the chamber to cause treated pollutant gas to raise the termperature of the incoming untreated pollutant gas comprising the step of re-routing pollutant gas from the input of the heated chamber to a storage chamber at the time of the changing of direction of gas flow, and from which storage chamber, the pollutant gas is later routed back into the heated chamber.
An apparatus for treatment of gas, vapor, or air-borne particulant pollutants comprising:
- a heated chamber in the form of a bed of sand, stone, or other material having heat-accumulating and heat-exchanging properties.
- means for heating through an external fuel source, a central portion of said bed to a temperature that will cause combustion or decomposition of the pollutant gas passing thereover;
- and
- means for alternating the direction of pollutant gas into the heated chamber for treatment to cause gas flow in opposite, alternate directions.
