Abstract
The integrated device for adsorptive purification and catalytic regeneration of VOCs is provided and includes a filtration adsorption coupling filter, a catalytic combustion regeneration box and a housing, where the housing includes a filter inner cavity and a combustion inner cavity that are communicated in sequence. The VOC exhaust gas is adsorbed and filtered by the filtration adsorption coupling filter. Moreover, under an operating condition of desorption regeneration, the catalytic combustion regeneration box is utilized to perform thermal desorption and regeneration on the filtration adsorption coupling filter, and catalytically combust and purify the VOC exhaust gas obtained by thermal desorption.
