Method of and Apparatus for Washing and Compressing Sulphurous
Acid and other Gases or Fumes.
I, ERNST PORÁK, Manufacturer, of Kienberg, Bohemia, in the Austro-
Hungarian 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 apparatus for the treatment of sulphurous acid or other
gases which have been produced by combustion or destructive distillation and are
intended for charging liquids or for other purposes, the sulphurous acid obtained
from sulphur or pyrites serving only as an example. The chief object of my device
is, to avoid the use of air pumps and compressors which are expensive and troublesome,
besides favouring the formation of sulphuric acid.
For this purpose I produce a forced circulation of water or other appropriate
fluid by means of a jet, which sucks the sulphurous acid or other gas as it arrives
from the combustion or distilling apparatus. The said jet discharges into a closed
tube which dips into the fluid contained in a closed reservoir, and thus the
sulphurous acid or other gas is at the same time washed and put under pressure
by the action of the jet itself. From the top of the reservoir the sulphurous
acid or other gas is led under the required pressure to its place of destination.
And in order that my invention may be more clearly understood, reference is
made to the accompanying drawings, in which
Fig. 1 is a sectional elevation of an apparatus embodying my invention;
Fig. 2 is a plan of the same; and
Fig. 3 is an axial section of the ejector or water jet, on a large scale.
The closed reservoir G is filled with an appropriate fluid, preferably water.
From its bottom this fluid is drawn by any suitable pumping machine E, and is
forced through the pipes F', injector F and pipe F3 back to the same reservoir G,
the pipe F preferably reaching into the fluid contained in G. The liquid thus
makes a complete circuit.
A represents a burner, retort, or other apparatus suitable for producing
sulphurous acid or other gases to be used for the saturation of liquids, such
sulphurous acid or other gases being led through the tubes B, C, D, and the
central pipe S into the ejector pipe F. As the pipe S is surrounded by the
jet of liquid descending into G, the sulphurous acid or other gas or fume
will be drawn from the tube D into the tube S and injected into the liquid
contained in G. It is therefore washed and compressed at the same time, and
may then be led through the circuit H, or through other suitable appliances to
its place of destination. In this condition the said gas is suitable for charging
liquids.
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
laim is:
1. The method of washing and compressing sulphurous acid and other gases or
fumes supplied by a sulphur burner or other gas generator, which consists in sucking
the said gases or fumes from the supply pipe by a jet apparatus adapted to force
them into a liquid contaiued in a closed receptacle, and maintaining a continual

page_text: circulation of the said liquid through the said jet apparatus and receptacle by
means of a pump, substantially as described.
2. Apparatus for washing and compressing sulphurous acid and other gases or
fumes, comprising in its construction a supply pipe D, water jet apparatus S, F2,
closed water reservoir G, pump E, and circulating pipe Fs, substantially as
described.
3. The combination of a sulphur or pyrites burner or analogous gas generator,
with a water jet compressing and washing apparatus, and a saturating or charging
apparatus, the whole being adapted to operate substantially as described.
