The invention discloses a waterless airborne-dust
processing apparatus used for building
engineering. The waterless airborne-dust
processing apparatus comprises a housing, and has an ingenious structure to realize waterless
processing, a water resource is saved, airborne dust on a
building construction place is sucked in a purifying bin by a suction fan through an air-supply
pipe, an electrostaticprecipitation net is arranged at the bottom of a material
discharge canister, fine airborne
dust particles are sucked in a suction housing, the large airborne
dust particles in the housing are bumpedwith a sidewall of a dedusting pipeline in the purifying bin and then fall into a material-collection groove and are introduced into the material
discharge canister, and then are discharged from thedischarge mechanism in the material
discharge canister, dedusting efficiency is high, the dedusting pipeline is set as an U shape, a bump area of the airborne
dust particles is increased, the airbornedust is introduced into the dedusting pipeline and then is intercepted, the intercepted airborne dust passes through a material-guiding
pipe and then is introduced into a storage bin, the dedusting effect is increased, a heating wire at a flow deflector outside the dedusting pipeline is energized for heating air in the housing, the bump frequency of the airborne dust in air and the outer wall ofthe dedusting pipeline is increased, and the dedusting effect is increased.
