An Improved Apparatus for Obtaining Distilled and Sterilised
Water.
I, JOSEF NAGEL of 73, Reichsstrasse, Chemnitz, in the Empire of Germany,
Coppersmith, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has for its object an apparatus for converting impure water into
good water fit for consumption, either by the water being evaporated and then
condensed, or simply boiled and then cooled down.
The apparatus, which is shown on the accompanying drawings in elevation and
vertical section, consists essentially of a cylindrical boiler or still A, with heating
tubes B on Field's system attached thereto, an upcast tube C, a second cylinder D
together with the tubes E and collecting vessel F contained therein.
The water which is to be distilled is conveyed from the supply tank g to the
boiler A by means of the pipe h, in proportion as it is used, which may be easily
regulated by means of a cock i and the quantity ascertained by means of the water
gauge glass k. The water is caused to boil by means of the furnace G, and the
steam resulting therefrom rises through the pipe C into the upper chamber 1, and is
finely divided in passing through the sieve in, so that an even trickling takes place
through the same, drops being formed, which fall through the tubes E and are
collected in the receiving vessel F and run off from thence in the form of water,
through the tube n.
The tubes E are constantly surrounded with cold water, which flows in at o and
out again at p, in such a way that a cooling of the distilled water takes place. The
water used for cooling the pipes may also, by the arrangement of a suitable tank,
be used for distillation. The cooling water which runs in in excess passes away
through the tube g.
In order merely to boil the water, the boiler A is sufficiently filled with it, which
is also done by means of the tube h, the cock i being closed and also the upcast
tube C, by means of the valve r. The steam evolved by the boiling exerts such a
pressure on the water that it is forced to escape through the tube S, it then rises
into the chamber l, flows through the sieve m and through the cooling pipes E into
the collecting vessel F, etcetera. This process is repeated as desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for producing distilled water characterised by an upcast tube C
connected with a boiler A, which tube C is surrounded with tubes E which are
encircled by a suitable cooling medium, and through which tubes E the steam
developed in the boiler A is condensed and conveyed from above downwards,
substantially as described and shown.
2. A modification of the apparatus described in Claim 1, for obtaining sterilised
water by means of boiling, characterised by the arrangement of an upcast pipe S
and a valve r, the water which is forced by the steam developed in the boiler A
during the heating of the water being caused to rise through the said tube S to
