Improvements in Apparatus for Washing, Scrubbing, and
Purifying Gas.
We, SIDNEY HERSEY, Engineer, and KIRKHAM HULETT & CHANDLER
LIMITED, Gas Apparatus Manufacturers, all of 3 and 4, Palace Chambers, Bridge
Street, in the City of Westminster, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in apparatus for washing, scrubbing and
purifying gas.
In carrying out our invention we use a gas and water-tight vessel of suitable
shape in cross section divided into a number of superposed compartments. In a
number of these compartments we place one or more roses having an inlet pipe at
the centre for the gas surrounded by a number of outlet pipes which are advan-
tageously slotted serrated or perforated at their lower ends which dip into water or
other liquids or impinge on the surface of the same.
We provide overflow pipes with regulating valves to vary the levels of the
liquid in the compartments as may be desired to vary the seals or to unseal
the pipes.
In addition to the compartments containing the roses we arrange one or more
additional compartments which may be placed above, below or between the
compartments containing the roses. In these other compartments we place a
number of vertical plates constructed preferably of corrugated iron such plates
being kept equidistant from one another by washers or indentatious and placed one
set at right angles to the set in the next compartment.
We provide an inlet for the gas at the bottom of the apparatus and an outlet at
the top: also an inlet for the water or other liquid at the top and an outlet at the
bottom of the apparatus.
At the top of the apparatus we provide a tumbler or tilting vessel which is
supplied with liquid from the water inlet and as the balance is disturbed the water
or liquid is thrown down on to a perforated plate preferably sloped towards the
centre of the vessel.
The working of the apparatus is as follows, viz. :-The gas enters the vessel at
the bottom compartment travels upwards through the centre tubes of the roses and
down through the slotted, serrated or perforated tubes into and through the water
in the compartment and upwards to the next series of roses and between the
vertically arranged plates to the outlet.
Water or other liquid as above stated is admitted at the top of the apparatus
and is thrown down by the tumbler or tilting vessel on to and through the
perforated plates being divided into streams and passing down between the plates
and through the overflow pipes fitted to the compartments containing the roses
passing from the lowest compartment by an overflow arranged for the purpose.

We, SIDNEY HERSEY, Engineer, and KIRKHAM HULETT & CHANDLER,
LIMITED, Gas Apparatus Manufacturers, all of 3 and 4, Palace Chambers, Bridge
Street, in the City of Westminster, 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 relates to improvements in apparatus for washing, scrubbing and
purifying gas.
In carrying out our invention we use a gas and water-tight vessel of suitable
shape in cross section divided into a number of superposed compartments. In a
number of these compartments we place one or more roses having an inlet pipe at
the centre for the gas, surrounded by a number of outlet pipes which are advan-
tageously slotted or perforated at their lower ends which dip into water or other
liquids or touch the surface of the same.
We provide overflow pipes with regulating valves to vary the level of the
liquid in the compartments as may be desired to vary the seals or to unseal
the pipes.
In addition to the compartments containing the roses we arrange one or more
additional compartments which may be placed above, below or between the
compartments containing the roses." In these other compartments we place a
number of vertical plates constructed preferably of corrugated iron, such plates
being kept equidistant from one another by washers or indentations and placed one
set at right angles to the set in the next compartment.
We provide an inlet for the gas at the bottom of the apparatus and an outlet at
the top also an inlet for the water or other liquid at the top and an outlet at the
bottom of the apparatus.
At the top of the apparatus we provide a tumbler or tilting vessel which is
supplied with liquid from the water inlet and as the balance is disturbed the water
or liquid is thrown down on to a perforated plate preferably sloped towards the
centre of the vessel.
To enable our invention to be fully understood we will describe it by reference
to the accompanying drawings, in which:-
Figure 1 is a longitudinal vertical section of apparatus constructed according to
our invention:
Figure 2 is a vertical section at right angles to the section shewn in Figure 1:
Figure 3 is a section on the line 3-3 Figure 1:
Figure 4 is a vertical section shewn to a larger scale through one of the roses;
and,
Figure 5 is a section on the line 5-5 Figure 4.
a is the gas and water-tight vessel and a', a', a², a², a³, the compartments into
which the said vessel a is divided. b, b are the roses in the compartments a', al of
the vessel a; b, the central inlet pipes of the said roses the said pipes being
bolted or otherwise suitably secured to the partitions separating the compartments,
and 62, 6 the outlet pipes which project downwards from the roses b. These outlet
pipes 3, 6, are slotted (or they may be perforated) at their lower ends as shewn in
Figure 4 and the said lower ends dip into water or other liquid e as shewn clearly
in Figures 1 and 2. The outlet pipes 6 are clustered around the central inlet
pipe b', as shewn in Figure 3 and to a larger scale in Figures 4 and 5.

page_text: d, d are the outlet pipes having the regulating valves d', d¹ to vary the levels of
the liquid in the compartments a' so as to vary the seals or to unseal the pipes as
may be desired.
e, e are the corrugated iron plates arranged in the compartments a², a³ and
maintained equidistant from one another by washers or the like. The plates in
one compartment a² are arranged at right angles to those in the adjacent
compartment.
In the drawing we have shewn the compartments containing the roses below the
compartments containing the series or sets of corrugated iron plates but we can
arrange the compartments containing the corrugated iron plates below or between
those containing the roses.
fis the inlet for the gas arranged in the lowermost compartment a³ of the vessel a
and g is the outlet for the same at the upper end of the said vessel whilst h is the
inlet for the water or other washing or purifying liquid at the top of the
apparatus.
is the tumbler or tilting vessel into which the water or other liquid flows
through the inlet & the said vessel being mounted on pivots, in such a manner
that when it contains a certain quantity of water its balance is disturbed and it tilts
and throws down the water on to the perforated plate ; which, as shewn in
Figure 1, is sloped towards the centre and through which it escapes and falls down
the apparatus.
The operation of the apparatus is as follows:-The gas enters the vessel a at the
bottom compartment a³ through the inlet f, travels upwards through the central
inlet pipes 6 of the roses b and down through the slotted outlet pipes 62 through
the water c into the lower compartment a', thence through the roses in the upper
compartment a from which it passes upwards between the lower series of
corrugated plates e and finally through the upper series of corrugated plates e and
the perforated plate j so as to escape through the outlet g.
As above stated water or other liquid is admitted at the top of the apparatus
through the inlet h and is thrown down by the tumbler or tilting vessel i on to and
through the perforated platej which divides it into streams, the said water or other
liquid then passing down between the corrugated plates e into the chamber a¹ and
finally escaping through the upper overflow pipe d'into the lower compartment a¹
from which it escapes through the lower overflow pipe d.
By this construction of apparatus it will be obvious that the gas on flowing up
through the apparatus is thoroughly cleansed of ammonia by reason of the large
amount of wetted surface supplied by the corrugated plates e, e and also of tar by
the roses b, b.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Apparatus for washing, scrubbing and purifying gas, consisting of a gas and
water-tight vessel divided into a number of superposed compartments some of
which contain roses and some sets or series of vertical plates preferably corru-
gated, the said vessel being provided with an inlet and outlet for the gas and an
inlet and outlet for the water or cleansing liquid, substantially as hereinbefore
described.
2. In apparatus of the kind described in Claim 1 the employment of roses each
consisting of a vessel having a central inlet pipe and a cluster of downwardly
extending outlet pipes slotted or perforated at their lower ends, substantially as
hereinbefore described.
3. In apparatus of the kind described in Claim 1 the employment of a tumbler
or tilting vessel adapted to project water or other liquid into the apparatus and of
a perforated plate for spreading or dividing the said water or other liquid, substan-
tially as described and illustrated.

page_text: 4. The combination and arrangement of parts forming the improved apparatus
for washing, scrubbing and purifying gas, hereinbefore d scribed and illustrated in
the accompanying drawings.
