DEVICE AND METHOD FOR REDUCING THE PRESSURE OF A FLUID CONTAINING GRANULES

摘要

A device and a method for reducing the pressure of a fluid containing granules. The device comprises a free space devoid of moving rotor blades and a housing with an inlet and an outlet. The shape of the wall within the housing and of the free space therein applies a centripetal flow component to the fluid containing the granules flowing therethrough. The pressure of the fluid containing the granules is decreased after the flow has passed through the device. The device and method further and impart a rotational motion to the fluid containing the granules in the area of the outlet, which is generally located in the central area of the free space.
