    • PROBLEM TO BE SOLVED: To provide a device for separating both very small light particles and large heavy particles from a gas flow.SOLUTION: This device includes a rotor 14 having a plurality of adjacent surface elements 16 accompanied by an intermediate gas flow clearance 48, and fitted rotatably in an ambient casing 12, and both large heavy particles and small light particles can be separated from gas by a compound action of electrostatic attraction and a centrifugal force of a centrifugal separator 10 of such a type that the casing has an inlet 18 for dirty gas, an outlet 22 for clean gas and an outlet 24 for separated particles. A charging unit 44 ionizes particles on the upstream side of a rotor 14. Since ionized light particles are attracted toward the surface of a surface element by electrostatic force, an electric field is formed between the adjacent surface elements 16 of the rotor. Particles accumulated on the surface element are thrown out toward the inner surface of the casing by a centrifugal force formed by the rotor, to be thereby drawn out through the outlet.
    • 要解决的问题:提供一种用于从气流中分离非常小的小颗粒和大重颗粒的装置。 解决方案:该装置包括转子14,转子14具有多个相邻的表面元件16,其伴随着中间气体流动间隙48,并且可旋转地安装在周围的壳体12中,并且大的重颗粒和小的光粒子都可以从 气体通过静电吸引的复合作用和离心分离器10的离心力,这种离心分离器10的类型使得壳体具有用于脏气的入口18,用于清洁气体的出口22和用于分离的颗粒的出口24。 充电单元44离子化转子14的上游侧的颗粒。由于电离光粒子通过静电力被吸引到表面元件的表面,所以在转子的相邻表面元件16之间形成电场。 通过由转子形成的离心力将积聚在表面元件上的颗粒向壳体的内表面排出,从而通过出口被抽出。 版权所有(C)2012,JPO&INPIT
