Description

Technical Field

[0001] The utility model relates to the technical field of heat storage combustion, and more specifically, to a heat storage type low-temperature catalytic combustion device. Background Art

[0002] Regenerative combustion technology is a technology that uses a heat storage body to recover flue gas waste heat, increase the temperature of the combustion air, and achieve efficient and clean combustion. Its principle is to heat the organic waste gas to a high temperature, so that the volatile organic compounds in the waste gas are oxidized and decomposed into carbon dioxide and water. At the same time, a special ceramic heat storage body is used to recover the heat generated by combustion, which is used to preheat the subsequent organic waste gas, thereby saving energy consumption and improving thermal efficiency. Regenerative combustion technology has the advantages of high treatment efficiency, wide application range (can treat low- and medium-concentration, multi-component organic waste gas), stable and reliable operation, and low maintenance workload. It is one of the organic waste gas treatment technologies currently widely used at home and abroad.

A gas supply valve 8 is provided on one side of the support base 1. A feeder 9 is provided on the other side of the support base 1. A first hose 10 for guiding flow is provided at one end of the gas supply valve 8. A combustion chamber 14 is provided at one end of the first hose 10.
