VACUUM-DISTILLATION APPARATUS Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: portion of initial fluid is fed to the evaporator through system 14. Hose 4 is wound on drum 3. The hose creates rarefication in the evaporator and unwinds belts 8,9. When the pressure of the initial fluid becomes lesser than the saturation pressure at a given temperature, the fluid boils up and its vapors are purified due to its contact with the adsorbent applied to belt 8. Hose 4 displaces the vapor in collector 16 due to moving the hose over the evaporator. The exhaust fluid is drained in system 15. EFFECT: improved design. 1 dwg
