according to the principle of bruedenkompression working destillationseinrichtung.

摘要

The present invention concerns a distilling means (10) operating on the thermocompressor principle. The distilling means (10) comprises a frame part (11), a boiling space (12) for the liquid to be distilled, a heating means (13) for heating the liquid to be distilled in said boiling space (12), a feed line (14) for conducting liquid to be distilled into the boiling space (12), a blower means (19) arranged to impart extra energy to the vapour formed from the liquid being distilled, whereby the temperature of the vapour rises on the discharge side of said blower means (19), and a discharge line (25) for discharging distillate from the distilling means (10). Inside the distilling means (10) is placed at least one heat exchange tube (17), along which the mixture composed of liquid being distilled and of vapour is arranged to flow, and a droplet separator)18) based on centrifugal separation. Inside the distilling means (10) is disposed substantially in the middle a central tube (22), inside which is placed an inner tube (23), whereby in the central tube (22) is defined an annular flow duct (24). The flow duct (24) is closed by a bottom (25) at a point substantially below the middle The annular duct (24a) below the bottom (25) of the annular duct (24) is provided with a discharge aperture (27). The blower means (19) is placed in the lower part of the distilling means (10), the mixture composed of liquid being distilled and of vapour that has been formed being arranged to flow from the heat exchange tube (17) through the central tube (22) to the blower means (19) provided to impart extra energy to the vapour and to direct the vapour into the annular duct (24a) below the bottom (25) of the annular duct (24), wherefrom the vapour discharges through the discharge aperture (27) into a condenser (28). In the annular duct (24) is provided a discharge connector (26) for removing the effluent water. The droplet separator (18) is a droplet separator with helical vanes (20), placed in the upper part of the annular duct (24).
