The invention discloses dust removal equipment for processing rice noodles. The dust removal equipment comprises a dust removal device, a purification device and a sucker; the sucker is connected witha draught fan by an air inlet pipe; the draught fan is connected with the dust removal device by an air inlet pipe; a material collecting tank is arranged below the dust removal device; the dust removal device is connected with the purification device by an air outlet pipe; and a wastewater collecting tank is arranged below the purification device. When the dust removal equipment works, the draught fan is started to suck dust-containing gases into the dust removal device by the sucker, and according to the design, dust is separated from the gases by virtue of gravity settling of the dust, andthe gases further advance, so that the aim of removing dust is achieved; the dust is removed by virtue of gravity, so that the cost is reduced; in the dust removal equipment, the dust-removed gases enter the purification device from the air outlet pipe, the gases are treated by using activated carbon and water, and odors in the gases are removed and are discharged through an air outlet, so that the aim of air cleanliness of a production line of the rice noodles is achieved, the production quality of the rice noodles is guaranteed, and the production demand is met.
