CYCLONE TYPE LIQUID-VAPOR SEPARATOR AND FORCED CIRCULATION TYPE EVAPORATOR USING THE SAME

A cyclone type liquid-vapor separator includes a chamber including: an internal space wherein the treatment liquid introduced into the internal space is depressurized and evaporated; a vapor outlet formed on a top of the chamber and through which vapors generated through the evaporation is discharged; and a concentrated liquid outlet formed on a bottom of the chamber and through which the concentrated treatment liquid is discharged; an inlet part coupled to a side surface of the chamber in a tangent line direction of an inner peripheral surface of the chamber, the treatment liquid introduced into the chamber is turned in the form of vortexes along the inner peripheral surface of the chamber, and at least one partition wall disposed in an area between the inlet part and the vapor outlet of the internal space of the chamber and protruding from the inner peripheral wall of the chamber to prevent mist contained in the vapors from moving upwardly.
