PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing and Scrubbing Gas.
We, SAMUEL CHANDLER, Junior, and JOSIAH CHANDLER, both of Central Works,
Kennington Oval, Engineers, and KIRKHAM, HULETT AND CHANDLER, LIMITED,
of 3 and 4, Palace Chambers, Bridge Street, Westminster, Manufacturers, all
in the County of London, do hereby declare the nature of this invention to be as
follows:-
-
Our invention relates to gas washing and scrubbing apparatus which is es-
pecially adapted for use in connection with small gas plants wherein there is no
motive power which can be utilized for driving a pump or operating an apparatus
which requires to be kept in motion, but which is also applicable for use with
other plants.
In an apparatus constructed according to our invention the pressure of the gas
is utilized for keeping the plates wet and we employ a suitable casing formed
with a series of chambers, each of which is adapted to hold a certain quantity of
water or liquor, circulating pipes being provided for allowing the water, to
gravitate from one chamber to another and for flushing out the said chambers
when required. The gas to be washed is preferably introduced into the chamber
at the lowest level from which it passes successively through the other chambers
to a suitable outlet. If desired, however, the gas may circulate in the opposite
direction.
The inlet for the gas into each chamber is through a kind of trap which con-
sists of an upwardly extending tube or passage over which is placed a hood or
cap extending downwards and having its lower end adapted to dip into the water
so that the gas which enters the chamber has to pass through the water in the
bottom of the same.
Beside or around this inlet trap a series of vertical plates is arranged upon
suitable cross bars or supports so that their lower edges dip into the water. With
this arrangement it will be understood that as the gas rises up through the water
and passes between the said plates it will cause the water to bubble up or rise
between the plates and so keep the latter in a wet condition.

We, SAMUEL CHANDLER, Junior, and JOSIAH CHANDLER, both of Central Works,
Kennington Oval, Engineers, and KIRKHAM, HULETT AND CHANDLER, LIMITED,
of 3 and 4, Palace Chambers, Bridge Street, Westminster, Manufacturers, all
in the County of London, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
Our invention relates to gas washing and scrubbing apparatus which is es-
pecially adapted for use in connection with small gas plants wherein there is no
motive power which can be utilized for driving a pump or operating an apparatus
which requires to be kept in motion, but which is also applicable for use with
other plants.
In an apparatus constructed according to our invention the pressure of the gas
is utilized for keeping the plates wet and we employ a suitable casing formed
with a series of chambers, each of which is adapted to hold a certain quantity
of water or liquor, circulating pipes being provided for allowing the water to
gravitate from one chamber to another and for flushing out the said chambers
when required. The gas to be washed is preferably introduced into the chamber
at the lowest level from which it passes successively through the other chambers
to a suitable outlet.
The inlet for the gas into each chamber is through a kind of trap which con-
sists of a number of short pipes screwed in the bottom plate of each chamber
and over which is placed a hood or cap extending downwards and having its
lower end adapted to dip into the water so that the gas which enters the chamber
has to pass through the water in the bottom of the same. In lieu of the said short
pipes a rectangular casting with flanges at the foot may be bolted to the bottom
plate.
Beside or around this inlet trap a series of vertical plates is arranged upon
suitable cross bars or supports so that their lower edges dip into the water.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which:-
Figure 1 is a sectional elevation of apparatus provided with a number of
superposed chambers;
Figure 2 is a sectional plan of the same; and
Figure 3 is a sectional end elevation.
a is the casing of the apparatus which is preferably formed of flanged cast iron
plates, the said casing being provided with a series of horizontal partitions b, b
which divide the said casing into a series of superposed chambers c, cl, c², etc.
d, d are the pipes, a series of which is screwed into each partition b and through
which the gas passes from one chamber to another and c, e and f are the longi-
tudinal plates which form the hood or cap over the pipes d, d the said plates
being jointed together so that the gas which passes up through the pipes d, d
shall be compelled to pass downwards beneath the plates e, e which, when the
apparatus is in operation, dip more or less into water contained by each chamber.
In the plates e, e above the plate f are apertures g, g through which the gas
passes to the pipes d, d of the chamber next above and so on as will be clearly
seen by reference to Figure 3.
h, h are the plates of metal or other suitable material which are arranged
vertically between the plates e, e and the walls of the apparatus and which are
maintained at suitable distances apart by distance pieces i, i. These plates are

derstood that as the gas rises up through the water and passes between the said
ates, it will cause the water to bubble up or rise more or less between the
ates h, h and so maintain the latter in a wet condition.
It will be understood that after the gas has passed through one chamber it
aters into the next superposed chamber and is again subjected to a similar washing
rocess and so on according to the number of chambers employed.

chamber below whence the water flows through the pipe

chamber p and u, u are covers over openings v in the sides of the chambers c, c¹,
the said openings being of sufficient size to permit of introducing or removing
the bundles of plates h, h into and from the apparatus.
Although we have described our apparatus as being provided with a series of
superposed chambers, it will be obvious that a series of chambers can be arranged
side by side. It will also be obvious that instead of having bundles of flat
plates h, h beside the tubes d, d plates may be arranged concentrically around
the said tubes or in any other desirable manner.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
30 we claim is:-
1. Apparatus for washing and scrubbing gas wherein the plates which are to
be kept in a wet condition are supported with their lower edges immersed in
water in such a manner that the gas to be treated and which is admitted above
the level of the water has to pass downwards through the water and to pass up
35 wards between the plates in order to escape, thereby producing a bubbling
action which maintains the said plates in a wet condition, substantially as de
scribed.
2. In apparatus for washing and scrubbing gas, the combination of a casing,
pipe or pipes projecting up through the floor of the said casing, a hood coverin
40 the said pipe or pipes and having its lower edges dipping into water and bundle
of plates arranged adjacent to the said hood in such a manner that the gas as
escapes from the said hood through the water will rise between the said plate
substantially as, and for the purpose, described.
3. The improved apparatus for washing and scrubbing gas, hereinbefore d
45 scribed and illustrated in the accompanying drawings.
