The invention discloses environmentally-friendly dedusting equipment, which comprises a box, a dust hopper and cloth bags. The box is fixed on a support. The bottom of the box is provided with the dust hopper, the bottom of which is provided with a dust discharging port. The dust discharging port is in threaded connection with a dust discharging cover. An air inlet pipe is connected at one side ofthe bottom of the box. One end of the air inlet pipe is connected to an air outlet end of a blower. An air inlet end of the blower is equipped with a metal filter screen layer. Several cloth bags arearranged inside the box. The top of each cloth bag is connected to a branch pipe of a jet pipe. By combining bio-enzyme in a honeycomb ceramic filter screen and an active carbon filter screen layer,various peculiar smell and harmful gases such as formaldehyde, benzene, toluene, xylene, smog and the like from materials in various occasions can be rapidly decomposed. With the arrangement of the cloth bags, dust is adsorbed onto the surface of the cloth bags. When much dust is gathered, dust will fall on the dust hopper under the action of gravity. When there is much dust, the dust dischargingcover can be opened to remove dust.
