Apparatus for Separating Water from Steam, Compressed Air,
or other Gas or Vapour.
I, WILLIAM NATILAN DACK, Consulting Engineer, No. 6, Old Lane, Noor Side,
Swinton, near Manchester, do hereby declare the nature of this invention to be
as follows:
My invention relates to an improved means of separating the watery particles
of wet steam or other vapour and is applicable to any purpose where dry vapour
is required.
It consists of a number of concs or conically formed pieces fixed together by
any suitable means. The smaller end of the first conical piece which faces the
flow of the vapour shall have inserted or cast therein a tube of any convenient
diameter (or for some purposes it may be closed).
This tube will extend towards or or beyond the larger diameter of the first
conical piece and on the larger diameter of this first conical piece another conical
or bell mouthed piece is formed. The smaller diameter of this second conical
piece shall be attached to or form part of the central tube and its smaller diameter
shall look in the direction of the flow of the steam or vapour and in the opposite
direction to that of the smaller diameter of the first cone. Attached by riba or
otherwise to this second or inverted cone is a third conical or bell-mouthed piece
which forms part of the conveying pipe after water has been separated. These
second and third conical or bell mouthed pieces form an annular port or passage
through which the dry vapour that passes on the outside of the first conical piece
may pass into the conveying pipe. The watery particles in this outside flow of
vapour being heavy will be thrown forward by impetus accross the port or passage
owing to their greater density into the the chamber or enlarged pipe in which
the conical tubes are fixed. This chamber forms part of the range of conveying
pipes and may be of any form to suit circumstances. In this chamber is formed
a pocket or well to which may be connected a steam trap to take the separated
water away. It is found by observation that the dyest steam or vapour flows
along the centre of conveying-pipe. This by its less gravity and friction flows at
a greater velocity than the heavier or more saturated vapour thus throwing this
heavier vapour towards the periphery of the conveying pipe. This added to the
condensation which naturally occurs by cooling at the periphery of conveying pipe
is thrown forward at the outside of first cone and caught in the chamber provided
for it.
The annular passage or port formed at large end of first conical piece may be
made in any other manner otherwise than by conically formed pieces or parts.
This invention is a development of that described in Specification of my prior
Application No. 6389-1898 of which ▾ received notice of acception of Complete
dated March 11th 1899.

I, WILLIAM NATHAN DACK, of 6, Old Lane, Moor Side, Swinton, near Man-
chester, in the County of Lancaster, Consulting Engineer, 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:-
1
My invention relates to an improved means of separating the watery particles
of wet steam or other vapour and is applicable to any purpose where dry vapour
in required.
i
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the drawing hereunto
annexed and the following explanation thereof.
The drawing shows a longitudinal section of my improved apparatus.
The invention consists of an outer casing we in which a number of cones or
conically formed pieces are fixed together by any suitable means, the smaller end
of the first conical piece 6 which faces the flow of the steam or vapour has inserted
or cast therein a cylindrical tube of any suitable diameter. This tube o
extends backwards beyond the larger end of the first conical piece b, and inside
the larger diameter of the said piece a second conical or bell-mouthed piece d is
attached in an inverted position, the smaller diameter of this second cone fits on
and is attached to, or forms part of the central tube c, this cone being placed in
the opposite direction to the first cone, that is, with its smaller end in the direction
of the flow of steam or vapour.
Attached by ribs or otherwise to this second or inverted cone is a third conical
or bell-mouthed piece e which is attached to or forms part of the conveying pipe f
which carries the dry steam or vapour on after the water has been separated.
The space between these second and third conical or bellmouthed pieces id
and e forms an annular port or passage through which the dry steam or vapour passes
into the conveying pipe f whilst the watery particles on the outside flow of the
vapour being heavy will be thrown forward by the impetus across this port or
passage owing to their greater density, into the chamber formed by the enlarged
part of the outer casing a in which the conical tubes are fixed.
This chamber forms part of the range of conveying pipes, and may be of any
convenient form to suit circumstances. In this chamber is formed a pocket or
well g to which may be connected a steam trap to take the separated water away.
It is found by observation that the dryest portion of the steam or vapour flows
along the centre of the inner tube c and the conveying pipe f. This owing to
its less gravity and friction flows at a greater velocity than the heavier or more
wet steam or vapour thus throwing the latter towards the periphery of the con-
veying pipe. This wet steam added to the water of condensation which naturally
occurs by cooling at the periphery of the conveying pipe is thrown forward from
the outer edge of the first cone & past the port or passage between the second-
and third cones and is caught in the chamber or pocket provided for it.
The annular passage or port formed at the larger end of the first conical piece b
may be made in any convenient manner other than by forming it by conical pieces
or parts.
г
This invention is an improvement upon or development of the invention for
which Letters Patent No. 6389 were granted to me bearing date the 16th day

page_text: 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:
The improved apparatus for separating water from steam, compressed air, or
other gas, or vapours, substantially as hereinbefore described and illustrated by
the annexed drawing.
