Description

technical field [0001] The invention relates to the field of industrial waste gas purification, in particular to an efficient integrated heat storage catalytic oxidation system for concentration fluctuating waste gas. Background technique [0002] In recent years, air pollution control has received widespread attention. Common air pollution control technologies are divided into two categories, one is the recycling method, and the other is the destruction method. The recovery technology is mainly aimed at the waste gas components with recycling value, while the waste gas with no recycling value often adopts the destruction method to directly destroy and remove the waste gas. Common recovery methods include: adsorption, absorption, condensation and membrane separation. Common destruction methods include: direct combustion method, catalytic combustion method, regenerative thermal oxidation method and regenerative catalytic oxidation method. The regenerative oxidation method ...
