Device and method for fluid purification

Abstract

A device is provided for separating solid particles or liquid droplets from a fluid. The device comprises an entry tube having an inlet port for receiving a fluid flow and a vortex section, the diameter of which decreases in the flow direction. The vortex section comprises at least one internal wall forming at least one helical channel. The helical channel preferably surrounds a core body extending along a central axis of the entry tube. The varying diameter end sections of the core body preferably have a conical shape. The device further comprises an annular exit port section having at least one peripheral exit opening, and an outlet tube extending along the central axis. According to an embodiment, the device is provided with a pre-separation unit in the form of a cyclone.
