NOVELTY - The utility model claims a dust filtering device for municipal road construction, comprising a transmission pipe; the left end of the transmission pipe is fixedly installed with a connecting plate close to the middle position; the connecting plate is movably installed with a connecting bolt; the front and back ends of the transmission pipe are fixedly installed with a supporting column at the position close to two sides; the position of the middle of the transmission pipe close to the left side is fixedly installed with an exhaust fan; the position of the middle part of the transmission pipe upper end to the right side is movably installed with a handle; the lower end of the handle is fixedly installed with a connecting frame. The utility model is capable of primarily filtering the dust through the graphene filter screen when filtering the dust; at the same time, it can absorb the particles in the dust through the polytetrafluoroethylene filter plate; during the period, it also can open the sprayer, so as to filter the dust; larger particles will be separated from the air under the driving of the liquid, and the liquid filter plate is wet, so it can better filter the dust.
