Improved Method of and Apparatus for Treating Smoke.
I, HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, 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 has for its object the washing and burning of smoke in the course
of its transit from the furnace to the chimney. To secure this end, I employ the
following parts :--
1st. A smoke scrubbing or scrubber chamber, or chambers, which are constructed
in the line of the chimney flue, and through which the smoke, as it passes, is
subjected to spray jets of water.
2nd. An engine fan water scrubber, or scrubbers into which the smoke is drawn
and whirled round by a fan wheel, whilst a jet or jets of water water play inside
the fan.
3rd. A smoke consumer proper, which is a chamber or chambers constructed in
the line of the chimney flue, and through which, as the smoke passes, it is subjected
to furnace heat.
In the accompanying drawing;
Fig. 1 is a plan view of an apparatus constructed according to this invention;
Fig. 2 is a section on the line 1-2; &
Fig. 3 is a section on the line 3-4, both of Figure 1.
Water
A is the smoke scrubbing chamber, which may be constructed of ordinary
brickwork, plastered with cement plaster, or of any other suitable material.
The transverse sectional area should be at least twice that of the chimney
fluc. The length of the chamber depends upon the degree of washing required.
For eight furnaces, the chamber is 4 feet wide, 10 feet high, and 16 feet long.
Three water spray jets B are fitted to each chamber, but there may be more or
fewer than three spray jets, according to the degree of washing required.
is supplied to the spray jets by hydraulic pipes, connected with either a raised
reservoir or a direct-acting pump. The pressure of the water head should be
sufficient to throw the spray jets of water forcibly up to the ceiling, and against
the walls of the chamber. The waste water, or water after use, drains away
rom the chamber through a syphon. Each water spray jet should be provided
vith a stop valve, so that its discharge may be regulated, or wholly cut off.
C is the engine fan water scrubber, which may be constructed of metal, or any
ther suitable material. Its capacity and speed of rotation should be sufficient to
ct as an exhaust fan to the furnaces, and at the same time to drive the smoke
orward, so as not to impede the action of the furnaces.

A water jet or jets is or
horoughly mill and wash or scrub the smoke, and keep the fan wet and clean and
ee from soot. The waste water, or water after being used in the fan, also drains
F through a syphon.
D is the smoke consumer proper, and consists of one or more blast furnaces
serted or placed, after the manner shewn in the drawing, in or on the floor of the
rizontal flue. Each blast furnace is provided with two doors a b, an upper door a
r the purpose of feeding the blast furnace, and a lower door b for the purpose
cleaning it out, & for supplying a natural through force draught or blast
the furnace. The quantity of air admitted below the furnace should be
gulated by a small disc air inlet, as the smallest quantity of air (the blast

fire to an incandescent heat.
The manner of making and using the invention so far as this has not been
described in the foregoing, is as follows:-
The smoke combustion, or gases which emanate from the furnaces, take a course
indicated by the arrows. The smoke passes, in the first instance, through the first
smoke scrubber chamber A. Here it is subjected to the action of the spray water
jets previously mentioned, while the waste water drains away through the syphon
delineated to the left, and thence into the drain or drain pipe outside.
The smoke,
on leaving this chamber, is deprived, by condensation, of the vapour it contained,
and it also parts with a material percentage of its sooty elements.
It then passes
on to the smoke consuming furnace, in which it is subjected to furnace heat,
whereby its character is materially improved by further destruction of its insoluble
or sooty particles. Then it passes on into a second smoke scrubber chamber B',
similar to that firstly above described, where it is again subjected to the cleansing
and dissolvent action of water. It here passes through the engine fan water
scrubber C, where it is whirled or revolved by a fan wheel in which jets of water
constantly play, thereby further depriving the smoke of deleterious and other
constituents which may have escaped destruction in the previous processes.
this chamber again the waste water is carried off through a syphon into a
drain which joins the main drain connected with the waste water system of the
smoke scrubber chamber firstly described. The cleansed smoke thereafter con-
tinues its course, and escapes through the chimney. The chimney obviously need
not be constructed as high as would be necessary where deleterious vapours are
discharged into the air under ordinary circumstances. It will thus be seen that in
the plan as above described there are two separate smoke scrubber chambers, an
engine fan water scrubber, and a smoke consumer proper having six furnaces.
This arrangement of scrubber chambers, fan water scrubber, and crematorium, may
be varied as to their relative positions in the line of the chimney flue, to suit
local conditions, such as ground space, or its conformation or otherwise, i.e., there
can be one or more smoke scrubber chambers or engine fan water scrubbers or
furnaces.
In
Having now described the nature of the said invention, as communicated to me
by my foreign correspondent, and explained the means for carrying the same into.
effect, I would have it understood, that it is not intended to limit or restrict the
invention to the precise arrangement of parts and apparatuses, nor to the precise
dimensions and forms of component or constituent parts hereinafter described with
reference to the accompanying drawing, as, when regard is had to the character
of the smoke and the degree of washing and burning of it that may be required,
these may be variously modified and applied without departing from the nature of
the invention, but what I claim is :-
1. The improved method of treating the smoke of furnaces hereinbefore
described.
2. The means as herein described, whether used separately or in combina-
tion as hereinbefore stated, for treating the smoke of furnaces, for the purpose set
forth.
