▎ 摘  要

NOVELTY - Graphene adsorption-regenerative catalytic combustion purification device comprises an exhaust gas pretreatment unit and an exhaust gas purification unit, where the exhaust gas purification unit is provided with a continuous combustion chamber and graphene porous ceramic heat storage in order from bottom to top body. The combustion chamber is provided with a gas nozzle and a primary-stage graphene catalyst for catalyzing combustion of volatile organic compounds (VOCs), and secondary-stage graphene catalyst provided in the graphene porous ceramic regenerator. The three-dimensional mesoporous graphene skeleton is provided with volatile organic compounds degradation catalyst. The exhaust gas pretreatment unit communicates with the combustion chamber via a heat exchange tube provided in the graphene porous ceramic regenerator, where the exhaust gas pretreatment unit includes alkaline graphene purification column and acid graphene purification column. USE - Graphene adsorption-regenerative catalytic combustion purification device. ADVANTAGE - The graphene adsorption-regenerative catalytic combustion purification device has high purification efficiency of volatile organic compounds and prevents catalyst poisoning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using graphene adsorption-regenerative catalytic combustion purification device, which involves: (A) passing volatile organic compounds exhaust gas into exhaust gas processing unit to perform pretreatment; (B) entering pre-treated volatile organic compounds exhaust gas into the combustion chamber to occur flameless combustion under action of the graphene catalyst; (C) entering the flameless combustion volatile organic compounds exhaust gas to the graphene porous ceramic regenerator to undergo catalytic degradation reaction with the latter stage graphene catalyst; and (D) degrading catalytically volatile organic compounds exhaust gas to undergo deep catalytic reactions.
