EVAPORATOR FOR SALT-BEARING SOLUTIONS Russian patent published in 1995 - IPC

FIELD: chemical industry and metallurgy. SUBSTANCE: evaporating apparatus has separator, up-going and down-going pipelines of evaporating solution, located on down-going pipeline tubular vertical heating chamber, second vertical heating chamber with branch-pipes of steam feeding and condensate removal, boiling-up chamber, circulation pump, made in the form of horizontal disk and hollow vertical blades and mounted in the second heating chamber vortex generator. The heating chamber is located in separator and coupled to up-going circulation pipeline through fitting on. In the heating chamber solution is swirled by blades and at a high speed is fed in boiling-up chamber, where solution is separated for fractions due to centrifugal effect. The evaporator allows to increase solution evaporation efficiency due to transformation of rectilinear movement of solution stream into swirling one, to decrease drops wasting and apparatus dimensions, to decrease metal consumption. EFFECT: increased productivity, decrease apparatus dimensions. 2 cl, 2 dwg
