Title: Apparatus for removing condensable vapours and a method of operating such apparatus
IPC: B01D5/00
Filed: 1960-04-25
Abstract: <PICT:0917733/III/1> Apparatus for removing condensable vapour, particularly water vapour, by exhausting a vessel 1 containing, e.g. material 3 to be vacuum dried, comprises a separator 6 for condensing the vapour under vacuum, the separator having a surface condenser 7 and a spray nozzle 12 for spray condensation of the vapours, the condenser and nozzle being arranged so that the injected spray liquid impinges upon the surface condenser and exchanges heat therewith. The apparatus is operated in two stages.  First, the vessel 1 is evacuated by starting a compression refrigerating machine 11, a rotary piston pump 27 and a gas ballast pump 28 whilst liquid is sprayed from the nozzle 12 on to the cooling coil of the surface condenser 7 and recirculated by a pump 16.  In this stage the compression refrigerating machine is throttled so that the temperature of the surface condenser is maintained above the freezing point of the sprayed liquid, e.g. between 0,5 DEG C. and 2 DEG C. Additional liquid for injection may be supplied from a pipe 20, supply being regulated by a valve 19 coupled to a temperature-sensitive element 29 in the separator wall.  If the liquid level in the floor 15 of the separator rises excessively the float-operated switch 23 closes and the valve 17 prevents further recirculation, surplus liquid being ejected through a relief valve 18.  In the second stage further spray injection of liquid is stopped and the liquid remaining in the floor 15 is pumped out through valve 18, after which pump 16 is switched off. The machine 11 is then operated at full throttle, thereby cooling the coil 7 considerably, e.g. to between 0 DEG C. and -50 DEG C., and causing residual water vapour to freeze on to the coil surfaces.
