NOVELTY - The utility model claims a pipeline type air purifying and sterilizing device for workshop of chemical plant, comprising a primary filter module, a dust charging module, a micro-electrostatic dust removing module and a nano photo-catalytic sterilizing module, which can realize the air purifying process of filtering-electrostatic dust-removing-photocatalytic sterilizing three-stage combination in the same device. the primary filtering module and the nanometre photocatalysis sterilizing module are respectively connected with the upstream and downstream of the air inlet/outlet pipeline. The dust charging module adopts high impedance carbon needle for corona discharge, ionizing air generating plasma, decomposing organic pollutant, killing bacteria, and charging the dust particles through. the micro-electrostatic dust removing module adopts plate electrode plate; the surface of the electrode plate is coated with graphene material to form an ordered micro-channel structure; the charged dust particles in the air are strongly adsorbed under the low pressure condition. The nano photo-catalytic sterilizing module adopts double-wavelength nano photo-catalysis technology, effectively removing VOCs, odour, bacterial virus and dust.
