简介 PURPOSE : A descending pipe and a fluidized bed reactor are provided to efficiently re-inject particles collected from a cyclone into the fluidized bed reactor. CONSTITUTION : A descending pipe(30) for a fluidized bed reactor is in the shape of a pipe with an inlet(31) and an outlet(33). The outlet includes a slanted cut side. The cut side of the outlet forms an angle of 30 to 60 degrees based on the surface of the ground. A screw(32) is arranged at the outer circumference of the inlet. The fluidized bed reactor further includes a fluidized bed reaction part, a cyclone, and a restricting member. The cyclone separates solid particles and gas. The descending pipe is connected to the cyclone and re-circulates the separated solid particles into the fluidized reaction part. The restricting member is installed under the descending pipe and restricts the flow of the solid particles.
