Improvements in Apparatus for Purifying Gas.
I, NARCISSE ALEXANDRE GUILLAUME, of 15, Rue du Louvre, Paris, in the
Republic of France, Engineer, do hereby declare the nature of my invention to
be as follows:-
My invention relates to apparatus for the purification of gas more especially
intended for use in connection with gas generators working by suction under
the action of a pump or motor. The purifying apparatus constructed in accord-
ance with my invention is provided with two chambers one above the other
through which chambers the gas to be purified passes in succession. The upper
chamber is for the purifying process and is divided into compartments by two
sets of partitions those of one set being provided with openings and conical nozzles
for dividing the gas and those of the other set being corrugated or provided with
a covering which will retain liquid and impurities. The gas after travers-
ing these compartments passes from the last of them into the lower chamber
from which it is withdrawn.
The two chambers aforesaid are separated from each other by a horizontal
partition and the plates which divide the upper chamber into compartments are
preferably arranged to slide between guides or angle irons.
At the upper part of each of the partitions which alternate with those carrying
the nozzles an opening or openings is, or are, formed for the passage of the
gas into the adjacent compartment.
The upper chamber is provided at one side with a cover fixed to levers mounted
on a shaft and balanced by counter-weights. The said cover is secured by means
of locking bolts round its edges. To prevent the escape of gas through the joints
of the cover I fix between the walls of the chamber and angle irons an elastic
packing which extends beyond the edge of the walls and angle irons and is kept
in position by a filling piece. When the bolts are screwed up the packing is
compressed and the escape of gas prevented by the tight joint thus formed.
The liquid and impurities entering with the gas are arrested in each compart-
ment of the chamber by the corrugated partitions or reticulated perforated or
other plates and passes downwards and through pipes into a reservoir arranged
on one side of the lower chamber. These pipes close the direct passage of the
gas from one chamber to the other and to secure this should dip into a sufficient
quantity of liquid in the reservoir.
an
There is overflow pipe for
regulating the level of liquid in the reservoir and conducting the
excess of liquid by suitable conduits to outside the apparatus. An auxiliary
passage may be provided to regulate the outflow of liquid. The gas enters the
apparatus at the inlet to the first compartment of the upper chamber and passes
successively through the several compartments thereof, and as it passes through
the nozzles of the partitions of the one set it strikes against the corrugated par-
titions of the other set or the sheets applied thereto which intercept the liquid
and impurities, the gas passing from compartment to compartment by the

page_text: openings in the last named partitions into each compartment successively and
after repeated impacts reaches the last compartment completely purified, in the
bottom of which compartment are openings forming a direct communication
between the upper and lower chambers. The gases pass by the said openings
into the lower chamber which constitutes a reservoir and is provided with a
depending and elastic partition, this chamber acting to a certain extent as a gas
pocket or bag. A discharge outlet for the gas leads from the said lower chamber.

Improvements in Apparatus for Purifying Gas.
I, NARCISSE ALEXANDRE GUILLAUME, of 15, Rue du Louvre, Paris, in the
Republic of France, 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 by the following statement:
My invention relates to apparatus for the purification of gas more especially
intended for use in connection with gas generators working by suction under
the action of a pump or motor. The purifying apparatus constructed in accord-
ance with my invention is provided with two chambers one above the other
through which chambers the gas to be purified passes in succession. The upper
chamber is for the purifying process and is divided into compartments by two
sets of partitions those of one set being provided with openings and conical nozzles
for dividing the gas and those of the other set being corrugated or provided with
a covering which will retain liquid and impurities. The gas after travers-
ing these compartments passes from the last of them into the lower chamber
from which it is withdrawn.
Referring to the accompanying drawings Figure 1 is a longitudinal section of
apparatus constructed in accordance with my invention the section being taken
ou the line A, B, of Figure 2. Figure 2 is a transverse section on the line C, D,
Figure 1 and Figure 3 shews drawn to a larger scale a gas tight joint which can be
advantageously employed in the construction of the apparatus.
a and are the two chambers aforesaid separated from each other by the
horizontal partition c. The upper chamber a is divided into compartments, by
the plates and e preferably arranged to slide between guides or angle irons f
The partitions are provided with openings and nozzles g decreasing from the
partition d towards the partition c. The partitions e are provided with corrugated
surfaces or reticulated, perforated or equivalently formed plates on the side
presented to the nozzles so as to present a large surface against which the gas
issuing from the nozzles impinges.
At the upper part of each of the partitions e and opening or openings i is, or
are, formed for the passage of the gas into the adjacent compartment.
The upper chamber a is provided at one side with a cover j fixed to levers-k
mounted on a shaft m and balanced by counter-weights n.
The said cover is
secured by means of locking bolts o round its edges. To prevent the escape of
gas through the joints of the cover jl I employ the arrangement shewn in detail
in Figure 3 which consists in fixing between the walls of the chamber a and the
angle irons p an elastic packing g of any suitable material which extends beyond

page_text: the edge of the walls and angle irons and is kept in position by a filling piece r.
When the bolts o are screwed up the packing is compressed and the escape of
gas prevented by the tight joint thus formed."
The liquid and impurities entering with the gas are arrested in each compart
ment of the chamber a by the corrugated partitions e or reticulated perforated
or other plates and pass downwards and through pipes s into a reservoir t
arranged on one side of the lower chamber b. These pipes close the direct
passage of the gas from one chamber to the other and to secure this should dip
into a sufficient quantity of liquid in the reservoir t. u is an overflow pipe for
regulating the level of liquid in the reservoir t and conducting the excess of
liquid by suitable conduits as shewn in Figure 1 to outside the apparatus. v is
an auxiliary passage to regulate the outflow of the liquid. The gas enters the
apparatus at the inlet to the first compartment of the upper chamber a and
passes successively through the several compartments thereof as indicated by
the arrows and as it passes through the nozzles g of the partitions d of the one
set it strikes against the corrugated partitions e of the other set or the sheets
thereof applied thereto which intercept the liquid and impurities; the gas passes
from compartment to compartment by the openings into each compartment
successively and after repeated impacts reaches the last compartment completely
purified, in the bottom of which compartment are openings y forming a direct
communication between the chambers a and b. The gas passes by the said
openings y into the lower chamber which constitutes a reservoir and is pro-
vided with a depending and elastic partition w, and is drawn off by the supply
passage formed by the walls 1 and 2 on the one side and the depending elastic
partition on the other.
If from any cause the gas is taken off too rapidly, the increased suction causes
the elastic partition w to approach the wall I thus reducing the section of the
gas passage; so that the said partition regulates the supply of gas, the chamber b
with its moving partition thus acts to a certain extent as a gas pocket or bag.
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-
1. Apparatus for the purification of gas comprising two chambers one above
the other one containing a series of perforated plates provided with nozzles for
directing the gas onto another series of corrugated partitions, or reticulated,
perforated, or like plates, for intercepting the liquid and other impurities which
How into the lower chamber which is provided with an overflow arrangement
substantially as hereinbefore described and illustrated in the accompanying
drawings.
2. In combination with a gas purifying apparatus as claimed in the preceding
claiming clause the arrangement in the reservoir chamber of an elastic partition
forming one of the walls of the gas supply passage for regulating the flow of
the gas therethrough substantially as herein before described and shewn in the
accompanying drawings.
