Abstract

The utility model relates to an RCO combustion heat accumulation air collection chamber which comprises a case, a connecting pipe and a heat accumulation pipe, wherein organic waste gas enters a catalytic cavity from a heat accumulation cavity through the connecting pipe for catalytic combustion, a great amount of heat energy is carried by the burnt gas, the burnt gas enters the heat accumulation pipe through a guide cavity, the heat accumulation cavity is subjected to heating treatment by a spiral section, the organic waste gas enters the heat accumulation cavity through an air inlet pipe, the organic waste gas is subjected to preheating treatment, and the heat energy carried by the organic waste gas can be effectively transferred to the heat accumulation cavity. The heat energy transfer enables the organic waste gas in the heat storage cavity to be preheated, and the preheating enables the organic waste gas to reach a certain temperature before entering the catalytic cavity, thereby being beneficial to accelerating the catalytic combustion process. Higher initial temperatures may reduce the time to reach the temperature required for combustion, thereby improving combustion efficiency. The preheating reduces the energy input required to reach the combustion temperature, thereby reducing the cost of organic waste gas treatment.
