| abstract | 1361282 Evaporators, falling-film type IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Feb 1972 [3 March 1971] 5923/71 Heading BIB A falling-film evaporator comprises a cylindrical column 1 surrounded by a heating jacket 21, the liquid which is to be submitted to evaporation being maintanied as a film on the inner wall of the cylinder by means of resilient demountable blades 19 made of organic polymeric material, preferably polytetrafluoroethylene, which are freely mounted in slots in horizontal arms 18 attached to rotor rod 5, the arrangement being such that, when the rotor is in motion, the blades 19 exert light pressure on the inner wall of the column. The column 1 and the rod 5 may be made of glass. A liquid mixture is supplied to the evaporator from slide funnel container 11, flow control tube 15 being adjusted by screw joint 14 so that the gap between socket 13 and the taper cone at the lower end of tube 15 is regulated whereby a steady feed of the liquid mixture to column 1 is achieved. The more volatile constituents of the mixture flows as vapour to condenser 9; and the condensate is collected in receiver 10. The resdiual liquid flows to receiver 3. Inert gas, such as nitrogen, may be passed through the evaporator from inlet 26. Reduced pressure may be applied at the neck 25 of receiver 10. The jacket 21 may be supplied with the vapours of toluene, xylene, o-chlorotoluene, o-dichlorobenzene, acetophenone or chloronaphthalene by boiling the appropriate liquid in flask 22. The evaporator may be used for separating o-dichlorobenzene from a solution of an organic polyisocyanate. |
