NOVELTY - The utility model claims a novel RCO active carbon adsorption and concentration catalytic combustion device, comprising a pre-drying filter device, a catalytic combustion tank, a mixed air blower, a desorption drainage fan, an adsorption tank; discharging drainage fan and discharging pipe; the filter box of the front dry-type filtering device is orderly provided with a front metal filter screen; the graphene filter module; and an active carbon filter screen or a glass fibre filter screen; each graphene filter of the graphene filter module comprises a filter frame and a continuous V-shaped folded graphene filter paper. The layout of the utility model is reasonable; the front dry-type filter device can perform three-stage purifying and filtering for the waste gas; the subsequent adsorption tank can absorb the pollutant in the waste gas; when the active carbon in the adsorption tank is saturated, it can make the pollutant into the catalytic combustion tank to burn by desorption; The purifying and filtering effect of the utility model is good; the efficiency is high; the energy consumption is low.
