PROVISIONAL SPECIFICATION.
Improved Method of Destroying the Noxious Fumes or Gases arising
from Chemical Manufactures or Processes.
I, ANDREW NOBLE BERTRAM, of Milngavie, in the County of Dumbarton, North
Britain, Paper Manufacturer do hereby declare the nature of this invention to be as
follows:
This Invention relates to an improved method of destroying the noxious fumes or
gases arising from chemical manufactures or processes.
The Invention has more particular reference to condensing and destroying the gases
and saturated vapours arising from recovering soda from the Lyes in paper mills but
the Invention may also be applied to Chemical works and all trades where noxious
fumes are germinated.
In accordance with my Invention the gases are drawn into an air tight brick
chamber with arched roof and which may vary in area according to the density and
volume of the gases; the drawing in of the air being preferably effected by a rotary
fan As the gases enter the chamber they are made to pass through a spray of water
which plays upon the boss and blades of the air propeller; by this means the gases
are caused to combine with the water and I prefer to further encourage the combination
or condensation by covering the brick floor with 12 inches or so of water.
:
Crossing at right angles to the Air propeller a wall is built to within, usually
about, two feet six inches of the arched roof. The blast of the air propeller drives
the saturated gases against this wall which is kept cool by a current of air passing
through the centre of it and in order that the gases which escape, being non-
condensed, may get free, the blast is caused to take its course over the top of the
wall and as it curls over, the blast will be met again by a spray of water under
pressure and its further progress is retarded by another wall which is built from
the roof to within, usually, about two feet of the floor. After the gases which remain
still in vapour have passed under this wall they will finally be subjected to another
spray of water before passing up the chimney. The gases which have reached the
last stage of operations are freed from any mineral or organic matters which carry
the noxious odor and pass up and out from the chimney.

Improved Method of Destroying the Noxious Fumes or Gases arising
from Chemical Manufactures or Processes.
1, ANDREW NOBLE BERTRAM Senior Partner of the Ellangowan Paper Company
Milngavie, in the County of Stirlingshire, North Britain 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 an improved method of destroying the noxious fumes or
gases arising from Chemical Manufactures or Processes.
My Invention has more particular reference to condensing and destroying the gases
and saturated vapours arising from Recovered Soda from Lyes, in Paper Mills, but
my Invention may also be applied to Chemical Works and all trades where noxious
fumes are generated.
In accordance with my Invention the Gases are drawn into an air-tight brick
chamber, with arched roof, which may vary in area according to the density and

page_text: volume of the Gases; the drawing-in of the air, being preferably effected by a
rotary fan; As the Gases enter the Chamber, they are made to pass through a spray
of water, which plays upon the boss and blades of the Air Propeller; by this
means the gases are caused to combine with the water, and I prefer to further
encourage the combination or condensation, by covering the Brick floor, with
12 inches or so of water.
the
Crossing at right angles to the Air Propeller, a wall is built to within, usually,
about two feet six inches of the arched roof. The blast of the Air Propeller drives
the saturated Gases against this wall, which is kept cool by a current of air; and
in order that the gases, which escape, being non-condensed, may get free, the blast
is caused to take its course over the top of the wall, and as it curls over,
blast will be met again by a spray of water under pressure, and its further progress
is retarded by another wall, which is built from the roof to within usually about two
feet of the floor. After the gases which remain still in vapour, have passed under this
wall, they will finally be subjected to another spray of water before passing up the
Chimney. The gases which have reached the last stage of operation are freed from
any mineral or organic matters, which carry the noxious odour, and pass up and out
from the Chimney.
In order that my said Invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings in which similar letters and
figures of reference indicate corresponding parts.
Fig. 1. is a General Plan of my Invention which shews the walls A A A A of the
arched roof chamber, B B are the walls upon which the Fumes are dashed, after
passing through the sprays C, and the Fan D. E is a damper which can be used at
pleasure, either to pass the Fumes through the Chamber or up the Chimney. F is also
another damper which can be closed at any time to retard the draught, or close the
chamber when not in use. G G are doors for admittance into Chamber. His
discharge water pipe to drain. I is main flue to chimney.
Fig. 2. is a Cross Section of the chamber mentioned in foregoing description of
Fig. 1. K is driving shaft with pulley at end. L perpendicular outline of Fan. M is
the circular frame of Fan. N are tye-bolts holding binding plates. O is water-pipe
for feeding sprays. P is discharge pipe for water from sprays, and the 12 inches
of water which cover the floor.
Fig. 3. is a Longitudinal section of the foresaid Chamber, and shews D a vertical
outline of the Fan, and its position. I is the port into main flue. B B are the walls
referred to in my description and Fig. 1. The space between walls are air-spaces-
His discharge water pipe to drain.
Fig. 4 is a Front Elevation of the Chamber mentioned in the foregoing figures.
GG are the entrance doors referred to in Fig. 1. B are the walls mentioned in
Figs. 1 and 3. N is the binding strap for tye-bolts. R is an inspection port-hole.
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
1st. The washing-out and removing the noxious smelling vapours and gases liable
to be evolved from all Chemical Manufactures or Processes.
2nd. Creates better draught in Processes.
3rd. Preserves all brick-work of Processes connected with Flues and the Chimnies.
Also prevents incrustation of Mineral matters in aforementioned.
4th. Particularly successful in washing out and removing the noxious smell, vapours
and gases, liable to be evolved from all forms of Roasters, used in Paper Mills.
5th. Also for destroying the noxious smells evolved, from the burning-off of the
Carbon in the Recovered Soda, which has been reduced to a solid, in the Roasters
of all types used in Paper Mills.
