PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing, Purifying, and
Scrubbing Gas.
I, JOSIAH CLEMENT CHANDLER, of 223, Brixton Road, in the County of
London, Gas Engineer, do hereby declare the nature of this invention to be as
follows:
-
This invention relates to improvements in apparatus for washing, purifying and
scrubbing gas.
In carrying out my invention I employ a gas and water-tight vessel divided
transversely into a number of water-tight compartments or bays by means of
division-plates varying in height and having other aud corresponding division-plates
suspended from the top of the vessel. In the spaces between the upper and lower
division-plates I place perforated plates, and in the said perforations I fix tubes.
The said compartments are charged with water or other liquid up to or above the
mouth of the tubes.
Overflow pipes are fixed to each compartment at different heights to carry the
liquid from compartment to compartment, and a regulating valve is applied to each
of these overflows in order to raise or lower the level of the liquor as necessity
arises to seal or bare the tubes.
Man-holes are placed on the side of the vessel in order to draw out and replace
my tubes, if necessary, in clusters.
I apply all necessary liquor cocks to the various bays for testing purposes, and a
clean supply of water at the outlet end of my machine must be provided for as
usual.
The gas enters the first compartment at the lowest water level, travels down
through the cluster of tubes, whereby it is minutely split up or divided, and impinges
on the water in the compartment, then rises through the said tubes and up the space
between the two division plates, over the top and down again through the next
cluster of tubes or devices and so on through the entire vessel leaving at the highest
water level, freed from its impurities.
Clean water is here run in, and the water-line in each bay being lower than the
one preceding, the water gravitates through to the opposite end and away by the
outlet.

*Improvements in Apparatus for Washing, Purifying, and
Scrubbing Gas.
I, JOSIAH CLEMENT CHANDLER, of 223, Brixton Road, in the County of
London, Gas 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 relates to improvements in apparatus for washing, purifying and
scrubbing gas.
In carrying out my invention I employ a gas and water-tight vessel divided into
a number of water-tight compartments or bays in which are placed perforated

water.
UL WHICH
Overflow pipes are fixed to each compartment at different heights to carry the
liquid from compartment to compartment, and a regulating valve is applied to each
of these overflows in order to raise or lower the level of the liquor as necessity
arises.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which
Figure 1 is a plan partly in section of my improved apparatus for washing,
purifying and scrubbing gas; and
Figure 2 is a sectional elevation of the same.
Figure 3 is a vertical transverse section of my apparatus looking in the direction
of the arrow 1, Figure 2, the right hand side of the section being taken on the
line, and the left hand side of the section on the line y, y.
Figures 4 and 5 are respectively a plan and elevation, drawn to an enlarged scale,
of part of one of the perforated plates with the tubes fixed therein.
Figure 6 is a sectional side elevation illustrating the construction of a modified
form of my apparatus; and,
Figure 7 is a sectional end elevation of the same.
Figure 8 is a plan of one of the chambers or compartments of this modified form
of apparatus with the cover or superstructure removed; and,
Figures 9 and 10 are respectively a partial inverted plan and a vertical section
shewing the arrangement of the perforated plates and tubes used in this modified
form of apparatus.
Similar letters of reference indicate corresponding parts in the several figures.
a is the outer casing or shell of the apparatus which is divided into a series of
compartments b, b, and c, c are the perforated plates supported in the several com-
partments and carrying the tubes d, d. e, f are the gas inlet and outlet respectively,
and g
hare the water inlet and outlet respectively. i, i are the overflow pipes for
conveying the water or liquor from one compartment to the other of the apparatus.
In the arrangement of my invention shewn in Figures 1, 2 and 3 (in which the
several compartments or bays are arranged side by side) the compartments or bays
are formed by division plates i, j, the division plates j, j extending upwards from
the bottom of the casing a and the division plates j', downwards from the top
thereof. The perforated plates c, e which are rectangular and have the tubes d, d
depending therefrom, as shown in Figures 4 and 5, are supported between the said
plates jon ledges k, k in such a manner that they can slide so that when man-hole
covers, with which the several compartments are provided are removed the said
perforated plates with their tubes can be drawn bodily out of the apparatus for
cleaning or repairs. The overflow pipes ii which are provided with regulating
cocks are attached to the plates j, j and are arranged in such positions that the
water level is lowest in the chamber b adjacent to the inlet e and highest in the
chamber adjacent to the outlet f.
The operation of the apparatus shewn in Figures 1, and 3 is as follows, that is
to say, the unpurified gas enters through the inlet opening e into the adjacent
chamber b, over the top of the division plate; and theuce passes down through the
tubes d, d and through the water into which the bottom of the said tubes dip and
thence under the division plate j' into the next adjacent compartment b. From this
compartment the gas passes downwards through the tubes d, d therein and into the
next compartment b and so on from one compartment to the other until it finally
escapes over the division plate j' to the outlet f. The wasbing water enters the
chamber b adjacent to the outlet f and containing the purest gas, and thence over-
flows through the pipe i into the adjacent chamber b, thence to the next chamber
and so on through all the chambers when it finally escapes through the outlet e so
that the unwashed gas first meets with the dirtiest water and in passing the tubes in 5
the last chamber comes into contact with comparatively clean water.

page_text: In the modification of my invention illustrated in Figures
to 10 I have repre-
sented the several compartments b, 6 as being arranged vertically one above the
other, the said compartments being separated by means of division plates 1³, 1³
arranged between the sections forming the casing a. The perforated plates c
carrying the tubes d form the bottoms of small chambers m, m connected with their
respective compartments b, 6 by means of tubular pillars n, n, which chambers m, m
and tubular pillars n, n practically form continuations or extensions of the said
compartments b, b.
In practice I prefer to make the said tube plates c, c circular so as to leave
spaces o, o through which the gas, issuing through the tubes d, d, can pass.
The operation of the apparatus last described is practically the same as that
previously described, that is to say, the gas entering through the inlet e at the
lower end of the apparatus flows into the compartment above, thence up through
the tubular pillars n, n into the chambers m, m, and thence down through the
tubes d, d and into the next chamber b. From the latter chamber the gas passes
up through the tubular pillars n, n and through the tubes d, d thereof into the next
chamber b and so on until it finally escapes through the outlet f.
The water inlet pipe g, the overflow pipes i, i and the outlet pipe h are so arranged
that the water will enter at one end of the uppermost compartment and thence
escape at the other end into the compartment next beneath it, thence through this
compartment into the next compartment and so on until it finally escapes through
the outlet h.
It is to be understood that in constructing my apparatus any desired number of
compartments or bays may be arranged according to the nature of the gas to be
washed.
"
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
(1.) Apparatus for washing, purifying and scrubbing gas provided with a series
of compartments in each of which is arranged a perforated plate or plates provided
with depending tubes dipping with their lower ends into the water in the bottom of
the compartment and so arranged that as the gas passes through one compartment
to the other it will be caused to flow down through the said tubes into contact with
the water, substantially as described.
(2.) In apparatus for washing, purifying and scrubbing gas and provided with a
series of compartments, each of which contains a perforated plate or plates carrying
depending tubes, arranging manholes in the walls of the various compartments in
such a manner that the perforated plates with the tubes carried thereby can be
readily withdrawn from the apparatus, substantially as described.
(3.) The improved apparatus for washing, purifying and scrubbing gas constructed
and arranged substantially in the manner hereinbefore described and illustrated in
Figures 1 to 5 of the accompanying drawings.
(4.) The modified form of apparatus herein before described and illustrated in
Figures 7 to 10 of the accompanying drawings.
