Description
【発明の詳細な説明】 （産業上の利用分野） この発明は、固体粒子の輸送方法に関するものである。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for transporting solid particles.
さらに詳しくは、この発明は、コアンダスパイラルフロ
ーによる固体粒子の高速輸送方法に関するものである。More specifically, the present invention relates to a method for high-speed transport of solid particles using Coanda spiral flow.
（従来技術とその課題）
従来、石炭、石灰、セメント、無機化合物、金属、ある
いは有機物の固体粒子を管路によって流体輸送するには
、空気、不活性ガス等の気体や液体の高速流に対してこ
れらの固体粒子を送入して輸送することが行われている
。(Prior art and its problems) Conventionally, in order to fluidly transport solid particles of coal, lime, cement, inorganic compounds, metals, or organic materials through pipes, it is difficult to transport solid particles of coal, lime, cement, inorganic compounds, metals, or organic materials through high-speed flows of gases or liquids such as air or inert gas. These solid particles are introduced and transported by means of transport.
この従来法においては、高速流体が乱流状態にあるため
、固体粒子は流体と乱流混合する。In this conventional method, since the high-speed fluid is in a turbulent state, the solid particles mix turbulently with the fluid.
このため、固体粒子は輸送の過程において輸送管の内面
壁と激しく衝突し、この内面を摩耗させる。この摩耗は
、輸送管を破損し、粒子の輸送を回動にする。For this reason, the solid particles collide violently with the inner wall of the transport tube during the transport process, causing abrasion of this inner surface. This wear damages the transport tube and causes the transport of particles to rotate.
また、乱流混合による粒子の管内壁、粒子相互間との衝
突は、輸送プロセスの圧損失、内壁の摩耗によって輸送
プロセスの制御を難しくする。粒子の形状の維持が必要
なものについても、従来の乱流混合による方法は適用で
きない。In addition, collisions of particles with the inner wall of the pipe and between particles due to turbulent mixing cause pressure loss in the transport process and wear of the inner wall, making it difficult to control the transport process. Conventional turbulent mixing methods cannot be applied to particles that require maintenance of particle shape.
ざらにまた、乱流混合によって大口の固体粒子を゛効率
的に行なおうとすれば、流体の高速化のために装置を大
型化しなければならなかった。大きな粒子形状のものに
ついても、この従来法では流体輸送に限界があった。Furthermore, in order to efficiently mix large particles of solid particles by turbulent mixing, it was necessary to increase the size of the equipment in order to increase the velocity of the fluid. Even with large particles, this conventional method has limitations in fluid transport.
このため、輸送効率、経済性に優れた固体粒子の流体輸
送の方法の実現が強く望まれていた。For this reason, it has been strongly desired to realize a method for fluid transportation of solid particles that is highly efficient and economical.
（発明の目的）
この発明は、このような事情に鑑みてなされたものであ
り、従来の乱流混合による輸送法の問題点を解決した、
固体粒子の輸送方法を提供することを目的としている。(Object of the invention) This invention was made in view of the above circumstances, and solves the problems of the conventional transport method using turbulent mixing.
The purpose is to provide a method for transporting solid particles.

輸送を行うことを特徴としている。(Structure of the Invention) In order to achieve the above object, the method for transporting solid particles of the present invention adopts a single Coanda spiral flow method in place of the high-speed turbulent mixed transport of the conventional method, and In particular, it is characterized by transporting solid particles using this Coanda spiral flow method.

制されるのである。In other words, the inventor of the present invention
- When a vector in the pipe radial direction is added to the pipe, the fluid is rotated,
Based on this circulation flow, a dynamic boundary layer is formed near the inner wall of the pipe,
It was discovered that the fluid moves at high speed in the direction of the pipe while drawing a spiral. When solid particles are mixed into this spiral flow, the particles move in the direction of the pipe while drawing a spiral, and contact between the particles and the inner wall of the pipe is suppressed.
このようなコアンダスパイラルフローの応用について検
討を行うことにより、特定の条件を採用する場合には、
固体粒子の流体輸送が高速で、効率的に、かつ粒子と管

である。By considering the application of such Coanda spiral flow, when adopting specific conditions,
It has recently been discovered that fluid transport of solid particles can be achieved at high speed, efficiently, and while suppressing collisions between the particles and the inner wall of the pipe. This invention is based on such new knowledge.
