An Improved Apparatus for Washing Gas.
I, WILLIAM WILSON HORN. of the firm of Horn & Son, of 151 Strand, in the
County of Middlesex, Patent Agent, (a communiation to me from abroad by
Charles W. Jarrell, of Shelby, Alabama, United States of America, Inventor) do
hereby declare the nature of this invention to be as follows:--
This my invention relates to a new and improved apparatus for washing and
purifying gas, and it consists of an upright vessel having at or near its top an outlet
for the washed or purified gas and at or near its bottom a curved inlet or supply pipe
extending upwardly within said vessel. An inverted cup-shaped deflector is supported
above the inner end of said supply pipe. A pipe extends downwardly within the
vessel and terminates slightly above the deflector aforesaid, and which pipe passes
through certain circular inclined water shelves which are arranged centrally within
the vessel one above the other. Suitable spray-pipes are located above the aforesaid
shelves and by means of the spray therefrom the gas is washed and purified.
In an alternative form of my invention 1 provide a long horizontal casing having
inclined bridge-walls situated at intervals along its length and formed with suitable
openings. There are also double inclined division walls alternating with the aforesaid
bridge-walls and having enlarged spaces formed in them. The gas when coming in
contact with these walls is washed by spray which is directed against them by suitable
spray pipes suitably arranged for that purpose.

An Improved Apparatus for Washing Gas.
I WILLIAM WILSON HORN, of the firm of Horn and Son of 151 Strand London
Middlesex Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Charles Waddy Jarrell of Shelby Alabama,
United States of America, Inventor,) and in what manner the same is to ba
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to certain new and useful improvements in purifying apparatus
for gas, and it consists substantially, in such features of arrangement construction
and combination of parts as will be hereinafter more particularly described and
claimed. The invention has for its object to provide an apparatus for the purification
of furnace gases, in which the gas is made to pass through a flue or tank, while a
spray of water descends to the bottom of the tank through the gas. Further, the
invention has for its object to provide an apparatus for the purification of gases in
which two sets of inclined watershelves are so arranged relatively to each other that
the gas is caused to take a zig-zag course in its passage upward, and the spray of
water descending from above is broken in its fall so that the gas is more thoroughly
broken up and by the attrition the globules or vescicles are broken and the foreign
matters are released and caused to descend to the bottom of the apparatus. Finally

page_text: the invention has such other objects in view as will more runy neremarter appear
when taken in connection with the accompanying drawings, wherein,
Fig. 1 represents a vertical elevation of a gas purifying apparatus constructed and
arranged in accordance with my invention, and,
Fig. 2 is a top or plan view thereof, and
Fig. 3 represents a longitudinal sectional elevation of a modified form of my
invention.
Fig. 4 is a vertical transverse sectional view taken on the line a x and
Fig. 5 is a similar view on the line y y.
Fig. 6 is a top or plan view partly cut out to disclose the interior arrangement.
In carrying my invention into effect I provide a suitable upright apparatus
having at its top an outlet for the escape of the purified gas, and having in its side
at or near the bottom, an opening for receiving the upwardly curved pipe leading
from and communicating with the flue or "down-comer" from the furnace. Supported
above the upper end of the curved pipe is a deflector which causes the incoming gas
to pass downwardly and thence up thro' the water contained in the reservoir at the
bottom of the apparatus. Around the interior walls or sides of the apparatus and
above the deflector are a series of inclined water shelves, reaching a short distance
within the apparatus, and, intermediate of these shelves are arranged circular inclined
water shelves which are supported centrally of the apparatus, and the edges or
peripheries of which extend far enough to come slightly under the side shelves. I
employ a central pipe for discharging a stream of water upon the deflector to keep
it cool, and a circular perforated pipe arranged at the top of the apparatus for
discharging a spray throughout the whole interior thereof. The result of the con-
struction described is that the water issuing from the upper circular spray pipe will
first fall upon the upper one of the inclined side shelves, then flow or bound off on
to the circular shelf beneath, and thence on to the next side shelf, and so on, thus
being completely broken up in its fall several times before it reaches the bottom.
As the water is falling and being thus broken up in its fall, the gas is passing
upwardly and in and out from beneath the two sets of shelves, and the effect is
thoroughly to purify the gas and render it fit for use for many purposes in the
arts.
Reference being had to the several parts of the drawings by the letters marked
thereon A represents a gas-purifier constructed in accordance with my invention
the same being provided at or near its top with an outlet B for the passage of the
purified gas to a main or other source and having an opening in its side at or near
the bottom for receiving an upwardly curved pipe or flue (leading from the side of
the pipe D which conveys the gas from the furnace.
Supported interiorly of the purifier A, immediately above the mouth of the curved
pipe C, is a hollow inverted-cup-shaped deflector E that is beld in place by brackets a
fastened to the sides of the apparatus A as shewn. This deflector is for the purpose
of causing the incoming gas to be deflected downward, so as to pass thro' the body
of water b, that is constantly contained in the reservoir or bottom of A up to the level
indicated. The level of the water may always be regulated and controlled by means
of the surface cock c and the water-gage d both in the side of the purifier A. For
the purpose of keeping the deflector constantly cool, a pipe e is adopted, and is
arranged, as shewn, by which to discharge a stream of water immediately on top of
the deflector. The reservoir may be emptied at any time thro' the discharge cock f
in the bottom of the reservoir at the side, and the foreign matter accumulating in
the bottom of the reservoir may be cleaned. out thro' the man hole g provided for that
purpose.
Supported centrally in the purifier A are two or more circular water-shelves hoh
the tops of which incline outwardly from the centre to the periphery, as shown, the
said shelves being arranged a suitable distance apart centrally within the apparatus A
and being supported by the several brackets i. These centrally arranged circular
inclined shelves are made to alternate with several water shelves arranged around
the interior sides of the purifier A, and of a width sufficient to project inward slightly

page_text: beyond the edges of the circular shelves so that water discharged on to the upper
side shelf will bonnd off on to the circular shelf beneath it, and so on, thus keeping
up a series of breaks in the fall of the water down thro' the interior of the apparatus.
The arrangement of the interior and side shelves with respect to each other is also
such as to compel the gas to follow a zig-zag course in its passage upward, and it
will be observed that the fall of water is almost at a right angle to the course of the
gas, thus tending to a more complete attrition and breaking up of the vescicles or
globules of the gas, and a consequent better purification. A further advantage
obtained by inclining both the surrounding side shelves and the centrally-arranged
shelves is that the water is caused to be projected into the path of the upwardly
flowing gas with greater certainty, and, besides, the flow of the water is better
facilitated throughout the interior of the apparatus, thus inducing better results.
The water is sprayed down thro' the interior of the apparatus A from a circularly-
arranged perforated pipe F, located above and having two supply pipes ss as
shewn.
In the modified form of my invention as illustrated in Figs. 3-6, I provide a
longitudinal conduit or passage way A', in which are arranged or constructed a
series of double inclined bridge-walls D', which alternate with a series of division-
walls E', throughout the entire length of the apparatus.
Sufficient space is left between said bridge and division walls to allow of a free
flow or passage of gas and in order that such gas be subjected to a greater extent
of treatment in its passage thro' the apparatus it is made to travel in a zig-zag path.
To enable such a path to be followed openings or spaces a¹ are left between the tops
of the bridge walls and the top of the apparatus, while like openings d' are provided
between the lower ends of the division walls and the bottom of the apparatus.
Openings are formed in the bridge walls at the bottom to enable me to have a
continuous water bed along the bottom of the apparatus, such bed being usually
maintained on a level with the top of the openings in the bridge-walls, so as not to
permit the passage of gas therethrough and compelling it to pass upwards over the
tops of said walls.
The spaces between the lower ends of the division walls and the bottom of the
apparatus are larger than the openings in the bridge walls which permit of the passage
of the gas through and over the surface of the water-bed.
Above the top of each bridge-wall are two transverse spray-pipes g¹ so arranged
as to send a spray of water down upon each inclined side of said walls and the result
of my whole construction of apparatus is that by the attrition the globules or vescicles
more thoroughly broken up, and consequently a much better purification
obtained.
are
In the bottom, at the end to which the pipe C connects, a chamber a² is provided,
in which heavy particles of dirt and foreign matter fall, and which may be cleaned
out at any time through an opening g provide 1 for that purpose and closed over while
the apparatus is in use.
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
claim is,
1. In a gas washer or purifier the combination with the upright vessel A, having
at or near its top an outlet for the washed or purified gas, and at or near its bottom
with a curved inlet or supply pipe extending upwardly within said vessel, of an inverted
cup shaped deflector supported above the inner end of said pipe and the pipe e extending
downwardly within the vessel and terminating slightly above the deflector substantially
as shewn and for the purpose described.
2. In a gas washer or purifier the combination with the upright vessel A, having
gas inlet and outlet pipes and provided with the inverted-cup-shaped-deflector of the
circular inclined water shelves h h, arranged centrally within the vessel, the
surrounding inclined side shelves j, alternating therewith, and the spray pipes located
above said shelves within the vessel A, substantially as shewn and described.

page_text: 3. The shell or casing having the double inclined bridge-walls formed with the
openings, and the double inclined division walls alternating with said bridge walls and
having the enlarged spaces in combination with spray pipes so arranged as to cast a
spray against the sides of the bridge walls, substantially as described.
