page_text: I, FRANCIS JOSEPH COLLIN, of Dortmund, Germany, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a tubular apparatus for cooling gases which is provided
with a special lower part or base carrying an arrangement of dip-pipes, whereby the
gas is forced, in whatever direction it may be passing through the apparatus, to pass
through the washing liquid contained in the said base, that is to say, either before or
after it passes through the cooler proper. -
The washing liquid trickles continuously from above into the base and is thus
always brought intimately into contact with the gases, whether the gases and liquid.'
flow in the same or in contrary directions.
The said apparatus is shewn on the accompanying drawing. Figure 1 shews a
longitudinal section through the upright cooler, while Figures 2 and 3'shew sections-
through the cooler, taken respectively above the preliminary washer d and through.

As shewn at Figure 1, the apparatus has at top a gas distributing chamber a, which-
chamber communicates through the system of cooling tubes 6 with the gas collecting

casing, so that the space round the cooling tubes can always be kept full of cooling:
water entering and flowing off respectively through the branches and l.
space c.
The gas collecting space c is also separated from the dip-pipe chamber or base d by..
means of a plate e in which the dip-pipes fare fixed gas tight, the lower ends thereof
being immersed below the level of the water, the height of which is determined by:
a discharge siphon g. Above the water level is provided a branch pipe h for the.
discharge of the gas.
The apparatus operates as follows:
Spraying nozzles i uniformly distributed under the cover of the gas distributing
chamber, lead the washing liquid in the form of spray into the gas distributing:
chamber a, from which, in the arrangement shewn, it flows down the inner surfaces:
of the cooling tubes b, falling thence through the gas collecting space c, and through:
the dip pipes f into the dip-pipe chamber d whence it flows off through the siphon y.
The cooling pipes 6 are energetically cooled by means of the cold water continuously
entering through and flowing off through L.
b
The gas enters the gas distributing chamber through the supply pipe m, and
is there already brought in contact with the spray of washing liquid, and is brought
into further intimate contact therewith in flowing down through the numerous cooling
tubes. The large number of cooling tubes offer so great a distributing surface for the
liquid and gas, that a sufficient washing is effected thereby.
Of course the external cooling of the tubes 6 at the same time effects a consider-
able reduction of the temperature of the gas passing through.
This gas
is finally obliged, after passing through the collecting space c, to
pass through the dip pipes and washing liquid in order to reach the discharge
branch.h.

page_text: The gas can also be made to travel in the contrary direction, the gas entering
through branch h being made to pass through the washing liquid before it flows
through the dip-pipes f, space c, and tubes b.
The mode of operating can also he modified so that the gas is not made to pass
through the tubes of the cooler but through the space surrounding these.
In this case the cooling water passes through the tubes b, which are all connected
to the same supply and discharge.
The supply of washing liquid however takes place from above as before, and
descends in the spaces between the tubes b, in intimate contact with the gas flowing
upward through the same spaces.

I, FRANCIS JOSEPH COLLIN, of Dortmund, Germany, 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:-
This invention relates to a tubular apparatus for, cooling gases which is provided
with a special lower part or base carrying an arrangement of dip-pipes, whereby the
gas is forced, in whatever direction it may be passing through the apparatus, to pass
through the washing liquid contained in the said base, that is to say, either before or
.after it passes through the cooler proper.
The washing liquid trickles continuously from above into the base and is thus
always brought intimately into contact with the gases, whether the gases and liquid
flow in the same or in contrary directions.
The said apparatus is shewn on the drawing accompanying my Provisional Specification
Fig. 1 shews a longitudinal section through the upright cooler, while Figures 2 and 3
shew sections through the cooler, taken respectively above the preliminary washer d
and through the cooling pipes b.
As shewn at Figure 1, the apparatus has at top a gas distributing chamber a, which
chamber communicates through the system of cooling tubes b with the gas collecting
space c. The system of cooling tubes is enclosed by a cover, a base plate, and a side
casing, so that the space round the cooling tubes can always be kept full of cooling
water entering and flowing off respectively through the branches k and l.
The gas collecting space c is also separated from the dip-pipe chamber or base d
by means of a plate e in which the dip-pipes f are fixed gas-tight, the lower ends
thereof being immersed below the level of the water, the height of which is determined
by a discharge siphon g. Above the water level is provided a branch pipe h for the
discharge of the gas.
The apparatus operates as follows:
Spraying nozzles i uniformly distributed under the cover of the gas distributing
chamber, lead the washing liquid in the form of spray into the gas distributing
chamber a, from which, in the arrangement shewn, it flows down the inner surfaces
of the cooling tubes b, falling thence through the gas collecting space c, and through
the dip-pipes into the dip-pipe chamber d whence it flows off through the siphon g.
The cooling pipes bare energetically cooled by means of the cold water continuously
entering through k and flowing off through l.
The gas enters. the gas distributing chamber through the supply pipe m, and is
there already brought in contact with the spray of washing liquid, and is brought

page_text: into further intimate contact therewith in flowing down through the numerous
cooling tubes. The large number of cooling tubes offer so great a distributing surface
for the liquid and gas, that a sufficient washing is effected thereby.
Of course the external cooling of the tubes b at the same time effects a consider-
able reduction of the temperature of the gas passing through.
This gas is finally obliged, after passing through the collecting space c, to pass
through the dip-pipes and washing liquid in order to reach the discharge branch h.
The gas can also be made to travel in the contrary direction, the gas entering
through branch h being made to pass through the washing liquid before it flows
upward through the dip-pipes f, space c and tubes b, to the discharge pipe m.
The mode of operating can also be modified so that the gas is not made to pass
through the tubes of the cooler but through the space surrounding these.
In this case, the cooling water passes through the tubes b, which are all connected
to the same supply and discharge.
The supply of washing liquid however takes place from above as before, and
descends in the spaces between the tubes b, in intimate contact with the gas flowing
upward through the same spaces.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
Apparatus for cooling and washing gases consisting of the combination of the
cooling apparatus b with a washing chamber d situated below it in which are dip-
pipes e open at top and dipping with their lower ends into the layer of liquid main-
tained in the said chamber the washing liquid being made to flow through the gas
channels of the cooler and through the dip-pipes into the bottom chamber, whereby
a very intimate contact between the gas and the washing liquid during its entire
passage through the apparatus is insured, substantially as described.
