I AUGUST KLÖNNE, Engineer, a subject of the King of Prussia and German
Emperor and a resident of the City of Dortmund in the Kingdom of Prussia and
German Empire do hereby declare the nature of my invention for IMPROVEMENTS
IN GAS WASHERS CALLED COLUMN WASHERS, to be as follows:-
My invention relates to those apparatus which are used to wash gas and to
purify it of tar ammonia and naphthaline. This is effected by dividing the gas
into fine streams and bringing it into close contact with water.
In my improved washer the gas is passed through a finely perforated plate which
is placed below the water in the water space. To the underside of this plate and
near its outer edge is secured a flange which serves so to speak to form a gas space
under the water.
The apparatus is constructed with a series of flat or conical shelves placed one
above the other and which form a series of trays to contain the water forming the
water space.
The gas enters below and passes through tubes inserted in the trays and under
caps which are placed on the perforated plate. These tubes may be of any shape
as round square or oblong. The gas streaming out from under the caps forms in
consequence of the flange on the underside of the perforated plate a gas space
under the latter and it passes through the perforations of the plate and rises
through the water above the plate where it parts with the ammonia originally
contained in it.
The washing water runs from one tray of the apparatus to the other in a zig zag
course through suitably arranged pipes until it finally runs off at the bottom by a
suitably placed cock. The height of the washing water is regulated by means of
adjustable regulators. These regulators are applied outside of the apparatus and
may either be fixed in a glass chamber or only the front plate of this chamber may
be made of glass so that the working may be from time to time observed.
The caps on the perforated plates are so arranged that they may if desired be
raised or lowered by means of an arrangement of bell crank levers and rods
from the outside of the apparatus and the perforated plates may also be made
adjustable.

I AUGUST KLÖNNE, Engineer, a subject of the King of Prussia and German
Emperor, and a resident of the City of Dortmund in the Kingdom of Prussia and
German Empire, 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 :-
My invention relates to those apparatus which are used to wash gas and to
purify it of tar, ammonia and napthaline. This is effected, according to my
invention, by dividing the gas into fine streams and bringing it in the finely
divided state into close contact with water, which is thereby enabled thoroughly
to wash it.
In my improved washer, the gas is passed through a finely perforated plate,
which is placed below the surface of the water in a water space.-To the undersidė
of this perforated plate, and near its outer edge, is secured a downwardly
projecting flange, which serves to form, so to speak, a gas space under the water,
which will prevent the adhesion of the water in the pores of the plate, and avoid
its cohesion with itself.
In the accompanying drawings, I have shown the improved washer in two forms,
Figs. 1 and 2, Sheet I, being respectively a sectional elevation and plan, partly in
section, of an oblong apparatus; and Figs. 3 and 4, Sheet II, similar views of a
cylindrical apparatus.
:
A is the body of the apparatus, which may be of any suitable material and
construction, and placed in any convenient position. Inside this body are a
number of partitions or shelves b, which may be flat or conical.
These flat or conical shelves form a series of trays to contain the water, which
I term the water space B.-The gas enters at E, and passes through tubes G
inserted in the trays b, and placed under caps H, which are carried by perforated
plates a. The plates are supported by standards bolted to the trays b, or in any
other convenient manner. The tubes G may be of any shape, as round, square, or
oblong, and may be arranged as shown at Fig. 2, or a number of smaller tubes may
be arranged in a row. The gas streaming out from under the caps H, forms, in
consequence of the flange c on the underside of the perforated plate a, a gas space
under the latter, and it then passes through the perforations of the plate a, and is
divided up into fine streams which pass through. the water above the plate a, where
the gas parts with the ammonia originally contained in it.
.
The washing water runs from one tray to another automatically in a zig-zag
course, through suitably arranged overflow pipes, that is to say, from d to e, from f
to g, from 1 to i, and so on, until it finally runs off at the bottom by a suitably
placed cock m. The height of the washing water is regulated by means of
adjustable regulators o. For this purpose the tubes which form these regulators
are raised or lowered by screws, as will be clearly understood on reference to the
Drawings. These regulators are applied outside of the apparatus, and are fixed in
a glass chamber p or in a chamber, the front plate only of which may be made

page_text: of glass, see Fig. 3, Sheet II, so that the outflow and graduation of the water can
always be observed from the outside.
The water from the hydraulic main, and from the condenser, may be conducted
direct, or after being cooled, into the second or third tray.
In the modification of the apparatus shewn at Sheet II, for the purpose of
straining the entire bottom uniformly, and to enable the gas to flow upwards with
as little loss of pressure as possible, the trays are made conical. The caps H on
the perforated plate a are arranged centrally, and can be pressed upwards by means
of a centre bar t and a screw t¹, the periphery of the perforated plate a being kept
down in position by means of the nuts 8.-In this arrangement the gas enters at
the centre. The perforated plates can also be held firmly in place between the
circumference walls of the apparatus, and can be made adjustable.
The caps on the perforated plates may also be so arranged that they may be
raised or lowered by means of an arrangement of bell crank levers, links, and rods,
from the outside of the apparatus, as clearly indicated at Fig. 3, Sheet II, of the
drawings. The gas, when thoroughly washed, will pass off at the upper part of
the apparatus by the pipe E¹.
Having now particularly described and ascertained the nature of the said
Invention and in. what manner the same is to be performed, I declare that what
I claim is
1. A gas washer constructed and arranged substantially as herein shown and
described.
2. In a gas washer, the combination of the shelves or trays b, having the tubes
or openings G, with perforated plates a, carrying caps H, arranged above the tubes
or openings G, so as to ensure the gas passing through the washing liquor, and a
flange or Hanges c placed underneath, and near the outer edges of the plates a, to
form a gear space, substantially as herein shown and described.
3. In a gas washer, the combination with the trays or shelves b, of the means
substantially as herein shown and described for regulating the height of the
washing liquor in the several trays or shelves, substantially as shown and
described.
4. In a gas washer, the means for raising and lowering the caps H and the
perforated plates a, substantially as herein shown and described.
