Improvements in Apparatus for the Distribution of Liquid in
Gas Scrubbers.
I, SAMUEL CUTLER of Providence Iron Works, Millwall, in the county of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows
This invention has for its object the construction of parts of gas scrubbers in such
a manner as to render the distribution of the liquid used therein regular, complete
and easily controlled while the various parts are so arranged as to be casily removed
for cleaning and other purposes.
The invention consists in attaching to the upper part of the scrubber a horizontal plate
of cast iron or other suitable material, which for the sake of convenience is made in
six or more, or less, segments and bolted together, each segment being provided with
flanges for that purpose. All round the upper side of each segment the plate is
thickened, raised or otherwise formed so as to make it into a shallow tray that will
contain liquid and support a top plate that is fixed to it, the space between the two
plates thus becomes a liquor chamber.
Both plates have a number of holes formed therein. In the lower one plugs or
distributors with hexagonal tops and secured by screws or other suitable means are
inserted, each plug having four or more, or less holes diverging from the perpendicular.
Over each hole in the top plate a small cover plate is provided, and in the centre of
this plate there is a hole which is ordinarily closed by a screwed plug.
Instead of making the distributors as before described they may each be formed of
a tube the bottom of which may be turned conically on the inside so as to receive a
conical plug having grooves in its edge, and supported by a rod that passes through
the cover plate. The rod is screwed at the upper part, so that by turning a nut the
disc or conical plug may be raised or lowered, and the way for liquid increased or
diminished. Instead of grooves on the conical plug, the said plug may be perforated,
and withdrawn by the rod before mentioned.

page_text: The action of the apparatus is exceedingly simple. Water or other liquid is supplied
to the liquor chamber by means of two or more, or less automatic syphons which
produce an intermittent stream with a pressure varying with the height of liquid in
the tank into which the long leg of the syphon enters. Instead of the liquid being
supplied through syphons an intermittent supply may be obtained by an ordinary
tumbling box arrangement. When the liquid has entered the liquor chamber and
risen sufficiently high, it will flow over and down the distributors, and as the exit
holes are made divergent, and the pressure variable the jets of liquid will fall below
at varying angles to the perpendicular thereby ensuring a constant and uniformly
wetted surface being presented to the gas.
In the event of the exit holes getting stopped it is only necessary in the case of the
distributors first described to unscrew the plug in the cover plate, when a brush or
other suitable instrument may be passed down the holes to remove the obstruction.
On a clearance being effected the plug may be replaced. In case of a stoppage of
any of the holes in the second form of distributor mentioned it is only then necessary
to give a few turns to the screw of the rod protruding through the cover plate when
the exit holes or spaces will become enlarged, so that on Hushing them, whatever
obstruction existed will be readily removed.
In case it is desired to remove for any purpose one or more distributors, it is only
necessary to take off a cover plate when the distributor immediately below the same
can be withdrawn.

Improvements in Apparatus for the Distribution of Liquid in
Gas Scrubbers.
I, SAMUEL CUTLER of Providence Iron Works, Millwall in the County of
Middlesex, 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:
This invention has for its object the construction of parts of gas scrubbers in such
a manner as to render the distribution of the liquid used therein regular, complete
and easily controlled, while the various parts are so arranged as to be readily removed
for cleaning and other purposes.
In order that the invention may be easily understood drawings are attached hereto
of which the following is a description. Fig. I is a plan of an overhead water or
liquid supply tank and shows the position of the syphon or tumbler tanks in duplicate
and the top of the scrubber. Fig. 2 is a vertical section through A. B Fig. 5, of the
plates forming the top of the scrubber. Fig. 3 is a vertical section of parts of the
same plates and exhibits in detail the form of the distributors, while Fig. 4 is a plan
of one of these same distributors. Fig. 5 is a plan of one plate or segment of the
top plate of the scrubber. Fig. 6 is an alternative form of distributor, Fig. 7 being
a plan of it. Fig. 8 is a plan of the guides, and Fig. 9 a plan of the disc relating to
Fig. 6.
The invention consists in attaching to the upper part of the scrubber a horizontal
plate E of cast iron or other suitable material, which for the sake of convenience is
made in six, or more, or less segments and bolted together, each segment being
provided with flanges for that purpose. All round the upper side of each segment
the plate is thickened, raised or otherwise formed so as to make it into a shallow tray
that will contain liquid and support a top plate F Figs. 2, 3 and 6, that is fixed to it,
the space G between the two plates thus becomes a liquor chamber, liquid being
admitted by the pipes D Figs. 1, 2 and 5.
Both plates have a number of holes formed therein. In the lower one E plugs or
distributors H with hexagonal tops and secured by screws or other suitable means, are
inserted, each plug having four or more or less holes I Fig. 3. diverging from the
perpendicular. Over each distributor is a removable cover covering the hole in the
top plate F, and in the centre of the covering plate is a hole ordinarily closed by
a screwed plug K, Fig. 3. A cover plate J is also shown over one of the holes in
Fig. 5.
Instead of making the distributors as before described they may each be formed of
a tube L Fig. 6, the bottom of which may be turned conically on the inside so as to
receive a conical plug or disc M having grooves N in its edge and supported by a
rod O that passes through the cover plate F. The rod O is screwed at the upper part,

page_text: so that by turning a nut P the disé or conical.plug M may be raised or lowered, and
the way for liquid increased or diminished. Instead of grooves on the conical plug,
the said plug may be perforated and withdrawn by the rod before mentioned.
The action of the apparatus is exceedingly simple. Water or other liquid is
supplied from the water or liquid tank Fig. 1, to the liquor chamber by means of
two, or more, or less automatic syphons placed in tanks QQ Fig. 1, which produce an
intermittent stream with a pressure varying with the height of liquid in the tank into
which the long leg of the syphon enters. Instead of the liquid being supplied
through syphons an intermittent supply may be obtained by an ordinary tumbling
box arrangement. When the liquid has entered the liquor chamber G and risen
sufficiently high, it will flow over and down the distributors HI FI Figs. 2 and 3, and
as the exit holes I are made divergent, and the pressure variable, the jets of liquid
will fall below at varying angles to the perpendicular thereby ensuring a constant and
uniformly wetted surface being presented to the gas.
In the event of the exit holes getting stopped it is only necessary in the case of
the distributors first described and shown in Figs. 2 and 3, to unscrew the plug in the
cover plate F, when a brush or other suitable instrument may be passed down the
holes to remove the destruction. On a clearance being effected the plug may be
replaced. In case of a stoppage of any of the holes in the second form of distributor
mentioned and shown in Fig. 6 it is only then necessary to give a few turns to the
screw nut P of the rod O protruding through the cover plate F when the exit holes
or spaces will become enlarged, so that on flushing them whatever obstruction existed
will be readily removed.
In case it is desired to remove for any purpose one or more distributors, it is only
necessary to take off a cover plate when the distributor immediately below the same
can be withdrawn.
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 :—
1st. The plates E and F forming the top of the scrubber and made and arranged as
herein described and shown on the drawings.
2nd. The distributors H and cover plates J Figs. 3 and 4 as herein described and
shown on the drawings, and,
3rd. The distributors constructed as herein described and shown on the drawings
as Figs. 6. 7. 8 and 9.
