Complete Specification Left, 24th June, 1895-Accepted, 27th July, 1895
PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Condensing and Washing Gas.
We, KIRKHAM, HULETT AND CHANDLER LIMITED, of 3 and 4, Palace
Chambers, Bridge Street, in the City of Westminster, Gas Apparatus Manu-
facturers, do hereby declare the nature of this invention (a communication from
Frederick Deacon Marshall, of Phillippa Vei, 8, Copenhagen, in the Kingdom
of Denmark, Engineer,) to be as follows:-
This invention relates to improvements in that class of condenser known as
battery condensers whereby the apparatus serves also as a washer.
According to this invention the gas enters through the inlet in the upper cover
of the apparatus and passes down between the pipes leaving the condenser through
the bottom outlet and the cooling water enters at the bottom of the apparatus and
passes upwards through a series of transverse pipes.
In the upper portion of the apparatus water is allowed to trickle over and
outside the transverse cooling pipes washing down and keeping the transverso
cooling pipes free from tar and naphthaline.
By this arrangement we provide an apparatus which is very compact and
powerful a very large cooling surface being offered to the gas, water being caused
to pass through the battery pipes instead of employing an air circulation as in the
ordinary arrangement.

Improvements in Apparatus for Condensing and Washing Gas.
We, KIRKHAM, HULETT & CHANDLER, LIMITED, of 3 and 4, Palace
Chambers, Bridge Street, in the City of Westminster, Gas Apparatus Manu-
facturers, do hereby declare the nature of this invention (a communication.
to us by Frederick Deacon Marshall, of Phillippa Vei, 8, Copenhagen, in the
Kingdom of Denmark, Engineer) 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 iu that class of condenser known as
battery condensers whereby the apparatus serves also as a scrubber.
According to this invention the gas enters through the inlet in the upper cover
of the apparatus and passes down between the pipes leaving the condenser through
the bottom outlet and the cooling water enters at the bottom of the apparatus and
passes upwards through a series of transverse pipes.
In the upper portion of the apparatus water is allowed to trickle over and
outside the transverse cooling pipes washing down and keeping the said cooling
pipes free from tar and naphthaline.

page_text: To enable the invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which.:—.
Figure 1 is a plan of the improved apparatus; and,
Figures 2 and 3 are scational elevations, the sections being taken on the
lines 2-2 and 3-3 respectively of Figure 1:
Figure 4 is a section on the line 4-4 of Figure: 3.
a, a are the walls of the apparatus which for convenience of construction are
made in sections, and b, b are, the cooling pipee, the said cooling pipes being carried
at their ends in sockets c, c formed on two opposite walls of the apparatus and
communicating with chambers d d formed in the said walls so that a cooling
medium will circulate from an inlet e in the direction of the arrows f, f, Figure 3;
all of the said parts being arranged in a well known manner and therefore requiring
no further description.
9, 9 are a series of troughs arranged over the cooling pipes b, and adapted to
be supplied with water through the tubes h, h provided with funnels, the said
troughs being notched at their edges as shewn most clearly in Figure 3, so as to
divide the water which overflows from the said troughs into fine streams and
thereby cause it to be distributed over the cooling pipes b; b. The water which
overflows from the said troughs trickles down over the pipes so that tar and other
impurities condensed from the gas on the pipes are washed off and carried to the
bottom of the apparatus whence they escape through an opening i, the gas passing
off through an opening covered by a cowl j. As the cooling water flows at
the bottom of the apparatus and cscapes at the top, it will be understood that
the hottest gas first comes in contact with the warmest of the cooling pipes.
and leaves the apparatus.after having passed over the coolest of the said cooling
pipes.
The apparatus constructed according to this invention is very compact and
efficient in operation, a very powerful cooling taking place owing to the use of
water in the cooling pipes instead of air which has usually been employed: in
apparatus of this class."
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be: performed,, we deolare that what we
claim is :-
1. In gas condensing apparatus of the kind wherein a series of tubes for the
circulation of a cooling medium are arranged in a suitable chamber, the provision
of means whereby water is caused to flow over the said tubes for the purpose of
preventing a deposit of tar or other impurity, upon the exterior of the, said tubes,
substantially as described.
2. In a gas condensing apparatus wherein a series of tubes for the oiroulating of
a cooling medium are arranged and in which wator is caused to, flow over the
exteriore of the said tubes, a circulation of water through the said. tubes. for
efficiently cooling the same, substantially as described.
3. The manufacture and use of the improved apparatus: for condensing and
washing gas substantially as hereiubefore desoribed and illustrated in the
accompanying drawings.
