Pneumatic conveying starting pipeline turbulent flow device

The utility model discloses a pneumatic conveying starting pipeline turbulent flow device, and belongs to the technical field of gas-solid two-phase flow. The pneumatic conveying starting pipeline turbulent flow device structurally comprises a conveying main pipe. A bypass pipeline which is evenly provided with a plurality of holes is arranged on one side of the conveying main pipe. The holes of the bypass pipeline are communicated with the conveying main pipe through grey pipes. A mother pipe which is connected with an air source and communicated with the bypass pipeline is sequentially provided with a hand valve, a pneumatic valve, a check valve and a throttling orifice plate in the air flow direction. By means of the pneumatic conveying starting pipeline turbulent flow device, the problems that solid and gas can not be well mixed and conveying is influenced at the low flow rate can be well solved.
