Simulation of the Dust-Air Flow Near a Rotating Disk Cylinder Suction Unit

Аннотация

We study a dust-air flow near a vertical rotating cylinder with suction unit placed on the lateral surface. On the basis of the developed computer model of this suction unit, we determine the influence of the disks mounted on the cylindrical surface on the intake air flow and on the capture of dust particles by the suction unit. We also determine the design and operating parameters of the proposed disk cylindrical suction unit promoting the decrease in the dust loss. The influence of the size of disks, their number, and the aspirated air flow on the dust removal is established. The proposed design of a rotating disk cylinder suction unit can be used in the aspiration shelters equipped with the function of dust-collecting chamber.
