Gases or Fumes, and for similar Purposes.
I, JAMES BALLANTYNE HANNAY, of Cove Castle, Loch Long, in the County of
Dumbarton, North Britain, Chemist, do hereby declare the nature of this Invention
to be as follows, that is to say :-
My said Invention has for its object to improve the construction and action of
apparatus for condensing, absorbing, or washing gases or fumes and for similar
purposes.
My improved apparatus contains one or more vertical screens of wire gauze or
other suitable permeable material. These screens which may be straight or cylindrical
or otherwise curved in horizontal section are supported in a suitable vessel so as to
extend down from a horizontal board or plate, and the space above the plate is divided
by a partition, on opposite sides of which are the inlet and outlet for the gases which
to get from one to the other must pass through the screens. The vessel is kept filled
with water or other suitable liquid to a level slightly higher than the horizontal board
or plate from which the screens depend so that the gases or fumes pass through and
the screens
become thoroughly washed by the water in passing through the screens,
minutely subdividing the gases and insuring intimate contact of every particle with
the water. The sublimate or fume separated by the water descends to the bottom of
the vessel and can be removed periodically. With this improved condensing apparatus
a comparatively very small pressure is required to cause the gases or fumes to pass
through the water and screens; and the apparatus may be advantageously used for
washing any kind of gas or funie and separating solid or soluble portions of the
mixture, or for acting on a liquid with a gas or gases.

BY COPIES
I, JAMES BALLANTYNE HANNAY, of Cove Castle, Lock Long, in the County of
Dumbarton, North Britain, Chemist, 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, that is to say :-
My said Invention has for its object to improve the construction and action of
apparatus for condensing, absorbing or washing gases or fumes and for similar
purposes.
My improved apparatus contains one or more screens of wire gauze or other
suitable permeable material. These screens, which may be straight or cylindrical or
otherwise curved in horizontal section are supported in a suitable vessel so as to
extend down from a horizontal board or plate; and the space above the plate is divided
by a partition, on opposite sides of which are the inlet and outlet for the gases, which
to get from one to the other must pass through the screens. The vessel is kept filled
with water or other suitable liquid to a level slightly higher than the horizontal board
or plate from which the screens depend, so that the gases or fumes pass through and
become thoroughly washed by the water in passing through the screens, the screens
minutely subdividing the gases and insuring intimate contact of every particle with
the water. The sublimate or fume separated by the water descends to the bottom of
the vessel and can be removed periodically.
On an accompanying sheet of explanatory drawings a convenient modification of
my improved apparatus is represented, figure, 1, being a transverse vertical section,
and figure, 2, a longitudinal vertical section.
The vessel, A, is in the form of a rectangular wooden box bound together by iron
straps or bars and rods. On a number of transverse beams or bearers, B, there are
fixed longitudinal bars, C, and boards, D; and between the inner ends of the boards
there is fixed a partition, E, in the form of an inverted channel and extending from
one end of the vessel, A, to the other. The inlet, F, for the gases or fumes is at one
end of the vessel, A, and communicates with the inside of the partition or inverted
channel, E, whilst the outlet, G, communicates with the space outside that partition or
inverted channel. The screens, H, which may be of wire gauze or other suitable permeable
material, flat pieces of simple wickerwork being found convenient and effective in
many cases, are fixed close under the boards, Ď, so as to extend downwards from
them. Water is filled into the vessel up to about the level of the boards, D, and
when the gas enters with a slight pressure it depresses the water down to the bottom
edges of the partition, E, or a little lower and then the gas passes towards both sides
through the water and through the screens, H, and being minutely subdivided by the
screens becomes well washed. Whatever remains in the gaseous form escapes
upwards at the outer sides of the screens, H, and passes off by the outlet, G. Fumes
or insoluble matters separated from the gas descend to the bottom of the vessel and

page_text: may be removed periodically through one or more doors, J ; whilst the water may be
renewed from time to time, inlet and outlet pipes, K, L, with stopcocks being
connected to the vessel for the purpose.
With my improved apparatus a comparatively very small pressure is required to
cause the gases or fumes to pass through the water and screens; and the apparatus
may be advantageously used for washing various kinds of gas or fume and for
separating solid or soluble portions of the mixture or for acting on a liquid with a gas
or gases.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
In apparatus for condensing, absorbing, or washing gases or fumes and for similar
purposes, arranging one or more vertical screens so as to extend down from a board
or plate in a vessel suitably filled with water and having an inlet and an outlet arranged
relatively to a partition or partitions so that the gas or fumes must pass through the
water and screens substantially as hereinbefore described.
