Improvements in Apparatus for Effecting the Absorption of Gases
by: Liquids, and for Cooling Gases,
I, ALBERT MÜLLER, of 34, Friedenstrasse, Berlin, in the German Empire,
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 bý the
following statement :-
The object of this invention is to effect as minute as possible a division or
atomization of alkaline fluids, for the purpose of absorbing gases, and this without
the use of steam or compressed air, as the immediate agent in producing the
atomization, since the condensed steam has an injurious effect upon the fluid, and
the air upon the gases, by diluting them.
The apparatus consists essentially in the application of one or more spindles
furnished with arms carrying buckets in a closed chamber, the spindles being set
in rapid rotation whereupon the buckets take up and atomize a portion of the fluid
which lies upon the floor of the chamber, and throw it into contact with the gases
which are passed into the chamber. The buckets possess at the lower part of their
fore end a flat slot, or holes corresponding to their whole breadth from which the
fluid is thrown and finely atomized as they rotate.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a plan of an apparatus constructed according to my invention for
effecting the absorption of gases by liquids and for cooling gases, the apparatus
being shewn closed:
Figure 2 is a cross section of the same shewing the buckets and spindle :
Figure 3 is a sectional side elevation of part of the apparatus shewing the
atomizer in action; and,
Figures 4 and 5 are respectively a longitudinal sectional elevation and an end
elevation of one pair of the arms and buckets drawn to an enlarged scale.
Through a chamber A enclosed on all sides runs the spindle.c made tight by
stuffing-boxes, and on one end of this spindle is carried a driving pulley d. On tho
spindle are a number of arms h, h, spirally arranged so that as the spindle rotates
only one bucket at a time enters the fluid which lies at the bottom of the chamber,
or fills itself.
'
The buckets h, h attached to the ends of the arms carried by the spindle are
open above and in front for the reception of the alkaline fluid, but closed below by
a wall n which is provided with a slot i or a row of holes and through these the
fluid which has been taken up is flung out forcibly as the spindle rotates rapidly,
and is atomized as finely as possible. The fluid thus atomized is driven against the
gases of combustion coming from a lime kiln or coke oven and composed of carbonic
acid gas, carbonio oxyde gas, sulphurous acid, etc. and which enter the top of the
chamber through a pipe attached at g. The fluid takes up the carbonic acid gas
and falls to the floor of the chamber to be atomized again.
The alkaline fluid which consists of a solution of carbonate of potassa or
carbonate of sodium and has the property of absorbing carbonic acid gas but not
carbonic oxyde gas is admitted through a pipe attached at a and is discharged
through a pipe at b. The gases of combustion not absorbed pass off through a
tube at f.
When the alkaline fluid has become sufficiently in pregnated with carbonic acid
gas, it is boiled in order to expel the said gas which is collected in a receiver and
is then ready to be liquefied.

page_text: It is evident that this apparatus will serve as well for cooling gases as for their
absorption.
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 :-
0
1. An apparatus for effecting the absorption of gases by fluids and for cooling
gases in which one or more spindles c are set in rapid rotation in a closed chamber A,
these spindles being furnished with arms carrying buokets h, h, which latter as the
spindle rotates take up a portion of the fluid which lies on the floor of the
chamber, project it forcibly, and atomize it, such apparatus being distinguished by
the fact that the buckets are furnished with a flat slot i or with a number of
holes through which the fluid is forced and is thus finely atomized substantially as
set forth.
2. In an apparatus such as is described in the first claiming clause, the spiral
arrangement of the arms which carry the buckets h, h upon the spindle o so that
only one bucket is ever allowed to dip into the fluid at a time as the spindle rotates
substantially as set forth.
3. The improved apparatus for effecting the absorption of gases by liquids and
for cooling gases substantially as hereinbefore described and illustrated in the
accompanying drawing.
