2 Claims.
This invention relates to a new and improved
gas washer and more particularly to apparatus
, of this type especially adapted for the final
23, which forms a coke receiving chamber 24
closed at the top by a removable cover Z5. ` The
chamber 24 is provided with division walls 26, as
shown in Figure 2, so that .alternate sections
discharge in opposite directions at their lower 'f
ends. The section shown in Figure l discharges
cleaning and drying of gases, as for example,
blast furnace gas, after the gas has had prelim
inary cleaning treatment in the usual stationary
spray towers or in other cleaning apparatus ‘ to the right between the perforated sloping walls
21 and 28, which define a space 29 for receivingsuch .as disintegrators.
Many forms of gas cleaning vapparatus have cleaning material. The wall 28 is supportedby
been developed, including simple spray towers the cross beams 30, and the upper wall 21 is se¢
and towers partly filled with banks of hurdles or cured to the cross beams 3|. It should be noted
of tile to secure better contact with the gas and that the solid division wall 23 continues down to
greater elimination of dust. The most eñ‘lcient meet the upper edge of the perforated wall 28.
The similar perforated walls 32 and 33 sup
of the usual forms of apparatus ordinarily re
15
duces the dust to approximately one-fourth of a ported by beams 34 and 35, respectively, fo-rm a
grain per cubic foot. These forms of apparatus space 36 on the opposite side of the main cham
do not, however, reduce the moisture content of ber to the space 29, to receive cleaning material.
The clean-out passages 31 and 38 are provided at
the gas to any amount approaching normal sat

It is a further object to provide apparatus of the perforated wall 32 on the incoming side of

The third series of spray nozzles 41 is provided
and moisture eliminating purposes.
It is an additional object to provide apparatus below the wall 28 and these nozzles are directed
having a reverse flow of gases making a double upwardly in order. to spray the under side of the

pass through the cleaning means for the purpose material in the space 29.

It is a further object to provide apparatus in heavy Wire mesh or of perforated sheet metal,
which the cleaning means may be rapidly and the openings being such as to permit ready flo-w
of gases and fluids without permitting the loose
easily removed and replaced.
Other and further objects will appear as the cleaning material to fall through. The cleaning 35
material, which may be coke, broken pieces of
description proceeds.
We have shown a preferred embodiment of our
invention in the accompanying drawings, in
which
Figure l is a vertical section _of the apparatus;
and
-
Figure 2 is a plan View of the apparatus.
The apparatus comprises a chamber II which
is enclosed by a circular shell I2 and enclosed at
45 the bottom by a conical shell I3. The top wall
I4 of the shell is provided with an inlet passage
I5 and an outlet passage I6. A drain pipe I1
leads from the lowest portion of the sump in the
conical bottom I3, .and extends to the sealing fit
ting I8 discharging into pipe I9. The pipe 20,
controlled by valve 2|, is provided for the intro
duction of fluid under pressure to blow sediment
which may collect, past the seal I8.
,
The upper portion of the chamber I I is divided
55 into two sections by a multiple dividing wall 22,
ceramic material or similar material providing
large contact areas, is introduced by removing
the cover plate 25 and permitting the material
to fall by gravity into the chambers 24. From 40
these chambers 24 the material flows both to the
right and left, as seen in Figure 1, and by gravity
fills-up the spaces 29 and 36.
The spray nozzles 4I are normally continuously
in-operation, wetting down the material in the 45
space 36. The gas to be cleaned enters down
wardly through the passage I5 and passes through
the material in the space 36 into the lower por
tion of the cleaning apparatus. As it passes
through this material, such as coke, in space 36, it 50
leaves in the bed of material a considerable '
amount of the dust and moisture which it con
tains.
The gas then makes a reverse bend and
ñows upwardly through the material in the space
29. This sharp turn has the additional tendency
2
to throw out particles of dust and globules of
water, which fall downl into the sump in the bot
tom of the chamber. The gas> passes upwardly
as come within the spirit and scope of the ap
pended claims.
We claim:
through the material in the space 29, which serves ,
1. In a gas washer, a closed vertical chamber,
to remove additional dust and also toI remove a
very large proportion of the water or moisture
remaining in the gas.
The material in the space 29 gradually be
comes clogged by the deposit of dirt and moisture
10 and is intermittently sprayed by means of the
nozzles 4d and 41 to clean the material. When
the material in either side of the chamber has
become so clogged as to impair its efliciency, it
may readily be removed by taking ciî the covers
15 39 or 40, when the material will flow out by grav
ity and new material will be’ allowed to flow in
by gravity through chute 24.
ing means to both sides of said means, and
means for introducing gas into the inlet cham 15
ber and for withdrawing gas from the outlet
chamber.
The circular cross-sectional shape of the cham
ber aids in causing the material to flow easily to
20 the discharge passages 3l and 38. The apparatus
is so designed that the gas cannot by-pass the
lower portion of the central partition but must
pass completely through both beds of coke or
other cleaning material. This material is cheap
25 and may be removed and replaced with low labor
cost so that the apparatus may be kept in eñicient
'operating condition. It will be understood that
the‘cleaning beds may be of varying thicknesses
and have different types and sizes of cleaning
30 material, depending upon the conditions to be
met.

While we have shown one preferred embodi
ment of our invention, it is capable of change
and modification to meet Varying conditions and
35 requirements and we contemplate such changes
