Abstract

PURPOSE:To generate a gently turning flow in a bent part and in a pipe after the bent part and prevent collision of grains, by jetting gas from gas injection nozzles provided in the front peripheral part in the bent part of a transport pipe which transports pulverized coal or the like of large quantity further in a long distance by gas. CONSTITUTION:A turning flow generating means (gas injection nozzle) 8 injecting gas tangentially from the periphery of a transport pipe is provided to the front of a bent part 2 of the transport pipe. Gas is interruptedly or continuously injected into the transport pipe from this nozzle 8. Injection of the gas generates a gently turning flow in the part 2 and in the pipe after the part 2 to prevent local collision of transported granular bodies additionally form a flow in a secondary side transport pipe of the bent part to a uniform streamline and reduce a total pressure drop.

多い程着しい。When transporting powder or granules using a high-pressure aJ concentration transport device such as a gas tank, some of the powder or granules may adhere to the inner wall of the transport pipe.
As a result, the pressure loss in the pipeline increases and the energy consumption increases.The longer the transport distance and the more curved pipes 1ji6, the more likely this effect will occur.

In addition to this, the particles collide with the inner wall (6) of the outer peripheral part of the pend part, causing local wear of the saddle part. Unfavorable phenomena such as increased pressure loss occur.

。As shown in FIG.
1- By providing a plurality of gas injection nozzles (8) that produce a flow in the outer peripheral part (7), and ejecting gas from the nozzles intermittently or continuously), the pend part and its After that, a gentle swirling flow is created in the tube, and the particles are heated to 1.
This prevents partial collisions and makes the flow of the secondary transport pipe at the bend part a partial streamline to reduce the overall pressure loss.

An arbitrary gas such as Urast gas or safety gas is released intermittently or continuously from this vent hole U3 to the bottom II1 of the transport pipe. Reduce the pressure loss caused by slowing down.
