Biomass wood powder conveying system

The utility model discloses a biomass wood powder conveying system, which comprises a spiral conveyer and a draught fan, wherein biomass wood powder is input into the draught fan by the spiral conveyer, an outlet of the draught fan is connected with a cyclone separator, a blanking opening of the cyclone separator is connected with a furnace-front stock bin, under the effect of the draught fan, the biomass wood powder is conveyed into the cyclone separator, air is pulled away by the cyclone separator, and the biomass wood powder without air falls into the furnace-front stock bin. The biomass wood powder conveying system has a storage function, the fuel storage quantity can be uninterruptedly increased, the manual in-time feeding operation is not needed, and the labor cost is reduced. Fuels conveyed by the draught fan are not directly supplied to a terminal equipment boiler, so the air quantity of the draught fan is not influenced by the load condition of terminal equipment, the constant air speed is maintained, the conveying process is very smooth, and the blockage is avoided. Before the fuels enter the furnace-front stock bin, clean air is separated out by the cyclone separator, so the environment pollution is reduced.
