Patent ID: 7972423

Claim:
Apparatus for stripping with strengthening and subsequent condensing and strengthening of an easily vaporizable component of an aqueous mixture, wherein the heat necessary for stripping and strengthening is transferred through a common heat transmission body ( 3 ), where the heat is derived from condensing the vapour generated by stripping and strengthening, which vapour via compression using a heat pump ( 26 ) has obtained the increase in boiling point necessary for condensation, said apparatus being comprised of two sections, namely a stripping and strengthening section or first section ( 1 ) and a condensing and final strengthening section or second section ( 2 ), said sections being joined around a common heat transmission body ( 3 ) forming a dividing wall, each section being further defined by a horizontal partially cylindrical housing ( 13 ) and an end wall at each end, and where each of said sections is provided with an atomizing rotor ( 4 ) adapted to throw liquid from each side from the bottom of the horizontal partially cylindrical housing ( 13 ) inward against the common heat transmission body, an axial liquid channel ( 5 ) providing a continuous passage of liquid through the apparatus extending along the bottom.
