Improvements in Apparatus for Washing Gas.
I, NARCISSE ALEXANDRE GUILLAUME, of 15, Rue du Louvre, Paris, in the
Republic of France, Engineer, do hereby declare the nature of this invention
to be as follows:-
"
This invention is more especially applicable to apparatus working under
suction. The gas enters in the form of a thin sheet in proximity to water fall-
ing as it is about to leave the apparatus the gas subsequently rising and tra-
versing the apparatus down through which the water flows, the gas being
directed into contact with the water by means of serrated hoods dipping into
the water in troughs so that the gas is repeatedly washed as it passes upwards
by water which passes downwards.
The apparatus is conveniently constructed of a series of superposed rectangular
troughs fitting into each other by ribs on the one engaging with grooves on the
other and secured together by means of vertical bolts or otherwise by joints
giving a sufficiently tight closure. The lowermost trough is mounted on columns,
supporting the apparatus and extending up beside the troughs and each pro-
vided internally with a screw, the movement of which is controlled by bevel
wheels and a pulley at the top of the apparatus. By means of this device the
several troughs can be lifted or lowered so as to secure a uniform tightening
of the joints.
Each trough is divided by a partition into two compartments, the one of which
is small, these small compartments when the troughs are superposed constitut-
ing a vertical conduit for the outlet of the washed gases, and the larger com-
partments constituting the troughs in which the washing takes place. The
troughs have each a splayed tube passing through the bottom of the said trough,
and a cup, both being so arranged that the lower end of the tube is immersed
in the water contained in the cup of the trough beneath. The gas enters each
washing trough by several long and narrow openings at bottom with sides ris-
ing into the trough and over these, hoods are placed which hoods have serrated
lower edges and are supported at their ends so that the serrations dip into the
water in the troughs and offer a gradual increase of the area for the passage of
the gas when the water level in the hoods falls.
The lowermost trough is provided with a tubular entrance conduit for the gas,
the said conduit extending into the lowest trough and being flattened out toward
its end so that the gas passes from this conduit in the form of a horizontal sheet
to meet the water which has served for washing the gas and which overflows in
a thin sheet from a box situated before the incoming stream of gas. The said
lowermost trough has a sloping bottom and the washing water passes off at the
lowest part through an outlet provided with a float valve. When the suction by
which the gas is drawn in becomes too strong the float valve closes.
The water enters through a pipe in the upper trough, this pipe being flexible
in order not to loosen the joint and the entrance for water may be controlled

and it flows through this tube into the cup beneath, which it overflows and
passes into the next trough and so flows down from trough to trough, till it
overflows the box in the lowermost trough in front of the incoming gas as afore-
said, which gas impinges against this water-and then passes through the open-
ings in the trough and under the hood and between the serrations and through
the water that surrounds the hood and which retains the impurities contained
in the gas. The gas thus successively passes through the water in each trough
and then descends in a washed condition through the vertical conduit formed
by the aforesaid smaller compartments constituting the gas outlet.

Improvements in Apparatus for Washing Gas.
I, NARCISSE ALEXANDRE GUILLAUME, of 15, Rue du Louvre, Paris, in the
Republic of France, 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 is more especially applicable to apparatus working under
suction. The gas enters in the form of a thin sheet in proximity to water fall-
ing as it is about to leave the apparatus the gas subsequently rising and tra-
versing the apparatus down through which the water flows the gas being
directed into contact with the water by means of serrated hoods dipping into
the water in troughs so that the gas is repeatedly washed as it passes upwards
by water which passes downwards.
And in order that my invention may be clearly understood, I will describe the
same with reference to the accompanying drawings, in which
Figure 1 is a longitudinal section of my apparatus.
Figure 2 is a transverse section thereof, part on the line A B C D E F and part
on the line G H of Figure 1.
Figure 3 is a horizontal section thereof on line M, N, of Figure 1.
The apparatus as shewn is constructed of a series of superposed rectan-
gular troughs a fitting into each other by ribs on the one engaging with
grooves on the other and secured together by means of vertical bolts 6 or other-
wise by joints giving a sufficiently tight closure. The lowermost trough e is
mounted on columns supporting the apparatus and extending up beside the
troughs and each provided internally with a screw e, the movement of which is
controlled by bevel wheels f and a pulley g at the top h of the apparatus. By
means of this device the several troughs can be lifted or lowered so as to secure
a uniform tightening of the joints.
Each trough a is divided by a partition into two compartments, the one of
which is small, these small compartments when the troughs are superposed
constituting a vertical conduit for the outlet of the washed gases and the larger
compartments constituting the troughs in which the washing takes place. The
troughs have each a splayed tube & passing through the bottom of the said trough
and a cup m, both being so arranged that the lower end of the tube k is immersed
in the water.contained in the cup m of the trough beneath. The gas enters
each washing trough by several long and narrow openings n at bottom (Figure 3)
with sides o rising into the trough and over these hoods P. are placed which

page_text: hoods have serrated lower edges and are supported at their ends so that the serra-
tions dip into the water in the troughs and offer a gradual increase of the area
for the passage of the gas when the water level in the hoods falls.
The lowermost trough is provided with a tubular entrance conduit r for the
gas the said conduit extending into the lowest trough c and being flattened
out toward its end so that the gas passes from this conduit in the form of a hori-
zontal sheet to meet the water, which has served for washing the gas and which
overflows in a thin sheet from a box t situated before the incoming stream of
gas. The said lowermost trough has a sloping bottom c and the washing water
passes off at the lowest part through an outlet u provided with a float valve v.
When the suction by which the gas is drawn in becomes too strong, the float
valve v closes.
The water enters through a pipe y in the upper trough, this pipe being flexible
in order not to loosen the joint and the entrance for water may be controlled by
a float.
In each compartment the water rises till it overflows the splayed tube k afore-
said and it flows through this tube into the cup m beneath, which it overflows
and passes into the next trough and so flows down from trough to trough till
it overflows the box in the lowermost trough in front of the incoming gas as
aforesaid which gas impinges against this water and then passes through the
openings in the trough and under the hood and between the serrations and
through the water that surrounds the hood and which retains the impurities con-
tained in the gas. The gas thus successively passes through the water in each
trough and then descends in a washed condition through the vertical conduit
formed by the aforesaid smaller compartments constituting the gas outlet
leaving the apparatus at X formed in the lowermost trough c.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In apparatus for washing gas more especially applicable to apparatus work-
ing under suction, the arrangement of superposed troughs, constructed as des-
cribed, up through which the gases rise and down through which the water for
washing the same descends, and the discharge of water into the lowermost trough
for a preliminary washing of the incoming gas substantially as herein before set
forth and illustrated in the accompanying drawings.
2. In apparatus for washing gas of the kind described mounting the troughs
by superposition of the same so as to form a closed column, the whole being
held together by screws and worked from outside, for example, by bevel wheels
and a pulley, substantially as herein before described and illustrated in the
accompanying drawings.
3. In apparatus for washing gas having superposed troughs, the means pro-
vided for effecting the admission and discharge of the gas at the lowermost
trough, substantially as and for the purpose herein before described and illu-
strated in the accompanying drawings.
4. The general construction, arrangement and combination of parts con-
stituting improved apparatus for washing gas substantially as herein before
described and shewn in the accompanying drawings.
