The invention discloses a dust removal device for
building construction, wherein the dust removal device comprises a base, unidirectional wheels, universal wheels, a first water pump, a first connecting
pipe, an arc-shaped
pipe, a first
nozzle, a second water pump, a second connecting
pipe, a first mesh cover, a second mesh cover, a water tank, a filter screen, an
activated carbon layer, a dust removal chamber, a fixed rod, an annular pipe, second nozzles, a push rod, a fan, a dustproof mesh, a dust suction port, a water inlet, a sealing cover and a driving motor; the water tank is fixed on the base, and the water pumps are fixed at the left and the right of the bottom of the water tank are the first water pump and the second water pump; the first water pump is connected with the arc-shaped pipe through the first connecting pipe; the arc-shaped pipe is provided with the
nozzle; the upper end of the tank is provided with the dust removal chamber; the bottom of the dust removal chamber is provided with the
activated carbon layer; the annular pipe is arranged above the interior of the dust removal chamber, and the fan is arranged at the rear side face of the dust removal chamber. Dustin air is quickly sucked and adsorbed to be removed by spraying, spraying and dust removal works on the ground are carried out at the same time, spray pipes are not required to be additionally added,and the labor intensity is reduced.
