Abstract: 1,096,221. Evaporators; suppression of entrainment; distillation of water. AQUACHEM. Inc. Dec. 24, 1964 [Dec. 26, 1963], No. 52500/64. Heading B1B. Droplets of liquid entrained in vapours from a vapourizing chamber 13 are removed in a separation zone 34 by passing the vapours firstly through wire mesh demisters 38, 39 which are washed by wash liquid from a spray system 42, second by directing the vapours by means of a bubble cap arrangement 47 into contact with a trough of wash liquid, and finally passing the vapours through a spray system 48 to a unwashed demister where any remaining droplets are removed, the wash liquid being at approximately the same temperature as the vapours. Hot condensate from a condenser 61 is returned through line 63 as wash liquid to the sprays and trough, overspilling wash liquid being collected in tray 37 and recycled. The high temperature of the wash liquid is maintained by providing heating surfaces in the trough 46 and tray 37, heat exchange of the liquid with the rising vapours while in the trough and during spraying also helping to maintain a high temperature. The apparatus may be used for the distillation of water. In the condenser 61 vapours are condensed by heat-exchange with feedwater entering through line 65, which feed water is further heated in heater 66 where it is in countercurrent flow with a minor stream of vapour rising through line 70 before being passed through apertured pipe 15 into the evaporating chamber 13 containing steam heated tubes 17. Sprays and baffles provided within the chamber 13 to some degree return droplets to the body of water therebelow. In a modification (Fig. 3) a bubble cap system, in which the vapours are directed by hoods 91 into the water in the troughs, together with a spray 89 and an unwashed demister accomplishes the separation, a liquid trap 96 maintaing the level of liquid in the troughs.

The body is formed with a handle 14 and a rectangular portion 16 on which is a second handle 15. The motor 19, such as a vane-type motor, is mounted in the body and has a driven shaft 20 rotatable about an axis 21. An eccentric portion 43 of the shaft is received in bearings 45 in a housing 46 on the unit 33 which consists of a plate 35 connected by flexible posts 47 to the body 13. A deformable rubber pad 39 on a metal plate 40 is removably secured to the plate 35 and a sheet of sandpaper 34 or the like is releasably retained on the pad by spring actuated clips 41. When air is supplied through a pipe 27 to the motor, the plate 35 is driven with a circular translatory motion. The air from the motor passes through a passage 29, Fig. 4, extending along the centre of a tube 62 of the aspirator which, at one end communicates with a pipe 69 leading to a container (12, Fig. 1, not shown), and at the other end communicates with a vertical passage 260 connected by a flexible pipe 58 to a passage 56 on the plate 35. The passage 56 is connected through an opening in the plate with channels 55 in the pad 39, the channels'being connected to apertures 52 in the pad and sandpaper sheet whereby the air passing from the motor through passage 29 to the pipe 69 causes a secondary flow of air and dust particles through the apertures 52, channels 55, passages 56, 58, 260 and tube 62 to the container (12). The air supply to the motor is controlled by a valve 31 actuated by a trigger 32. In another embodiment, the valve is actuated by a plate like element on the upper part of the body. In a further embodiment the sandpaper carrying assembly is reciprocated. In another embodiment a rotary vane-type motor drives a circular sanding head with an orbital movement, the head being disposed within a resilient shroud adjustably mounted on a part of the casing. In yet a further embodiment, the circular sanding head is rotated.
