Abstract (en)

[origin: WO9855194A1] The invention relates to a method for separating solid material from water, comprising providing an enclosed space, supplying an air flow into the space, generating a strong vortex in the air flow, feeding a mixture of water and solid material in dosed manner into the air flow, causing the water to evaporate out of the mixture in the air flow and discharging the solid material and the air from the space, wherein the air flow in the space is guided in one principal direction from the feed to the discharge. The invention further relates to a device for performing this method. The device comprises a conical chamber, an air supply conduit debouching into the chamber tangentially at a large diameter thereof and an elongate channel which connects onto a small diameter of the chamber and which is provided with an air discharge connection on an opposite end, wherein the channel extends away from the chamber.
