Improvements in or relating to Apparatus for Washing or Purifying
Smoke or the Products of Combustion from Boiler or other
Furnaces or Fireplaces..
I, GIOVANNI MUGNA, of 5, Baratti Street, Forli, Italy, Engineer, do hereby
declare the nature of this invention to be as follows: —
This invention relates to an apparatus for washing or purifying smoke or the
products of combustion from boiler or other furnaces or fire-places.
And in order that the invention may be easily understood I will proceed to
describe same with reference to the drawings hereunto annexed.
Referring to the drawings-Fig. 1 is a vertical sectional view of the apparatus.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a cross sectional view on line G-T Fig. 1.
Fig. 4 is a cross sectional view on line K-L Fig. 1.
Fig. 5 is a cross sectional view on line m-n Fig. 1.
Fig. 6 shows the apparatus according to one method of applying same for
washing the smoke or products of combustion from the furnaces of locomotives.
Similar letters of reference indicate corresponding parts throughout.
A are vanes of fan serving to draw the smoke or products of combustion coming
through the washing water in the bottom of the tank C and eject same through
the outlet G. as indicated by the arrows de f.
B is smoke box or chamber into which the smoke or products of combustion
are led through the inlet pipe H in the direction of the arrows a b c—the lower
(and contracted) part of said chamber B terminating a little distance above the
top of the washing water in the tank C and is provided with a flange or circular
disc P9
which limits the space or passage st through which the products of
combustion pass after having been washed by the water agitated by the revolving
vanes D.
C is tank to contain water and advantageously provided with means to auto-
matically keep same constantly supplied with water at or about the level of
the line mn.
DD are revolving arms or agitators partly immersed in the water in the
chamber C and against which said revolving vane throws the smoke or products
of combustion.
E is tap (of any suitable construction) for discharging dirty water.
Fis pulley which sets in motion the vertical spindle F¹ on which latter are
fixed the vanes A and D.
The pulley is revolved by a belt for instance in the manner shown in the
diagram Fig. 6 or said pulley or the spindle F¹ may be revolved in any other
desired and suitable manner.
Gis outlet through which the products of combustion are discharged from the
outlets after being washed or purified therein.
His inlet through which the products of combustion are led into the apparatus

page_text: said inlet H being controlled by valve V or any other suitable valve to regulate
the admission.
is tap by which is regulated the supply of water coming through the pipe z
to the tank C.
y is oil feed pipe.
It will thus be seen that the products of combustion are drawn in through the
inlet H and passed down through the chamber B and by the revolving vanes D
are forced into the water towards the centre of the tank C whence they escape and
pass up through the annular passages and are ejected from the apparatus by
the exhaust fan A through the outlet C as indicated by the arrows abcde and f.
In Fig. 6 a railway car containing this apparatus and a motor to revolve the
vanes is shown attached to a locomotive with a pipe O leading direct from the
funnel of the locomotive so as to convey the smoke or products of combustion of
the latter direct into my apparatus.

Improvements in or relating to Apparatus for Washing or Purifying
--Smoke or the Products of Combustion from Boiler or other
Furnaces or Fireplaces.
I, GIOVANNI MUGNA, of 5, Via Baratti, Forli, Italy, Engineer, do hereby
-declare-the-nature-of-this-invention_and_in_what_manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to an apparatus for washing or purifying smoke or the
products of combustion from boiler or other furnaces or fireplaces.
And in order that the invention may be easily understood I will proceed to
describe same with reference to the drawings filed with the Provisional Specifica-
tion and also with reference to the drawings hereunto annexed.
Referring to the drawings left with the Provisional Specification herein--
Fig. 1 is a vertical sectional view of the apparatus.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a cross sectional view on line G-T Fig. 1.
Fig. 4 is a cross sectional view on line K-L Fig. 1.
Fig. 5 is a cross sectional view on line mn Fig. 1.
Fig. 6 shows the apparatus according to one method of applying same for
washing the smoke or products of combustion from the furnaces of locomotives.
Similar letters of reference indicate corresponding parts throughout.
A are vanes of fan serving to draw the smoke or products of combustion coming
through the washing water in the bottom of the tank C and eject same through
the outlet G as indicated by the arrows de f.
B is smoke box or chamber into which the smoke or products of combustion are
led through the inlet pipe H in the direction of the arrows a bc-the lower
(and contracted) part of said chamber B terminating a little distance above the
top of the washing water in the tank C and is provided with a flange or circular
disc pq which limits the space or passage t through which the products of
combustion pass after having been washed by the water agitated by the revolving
vanes D.

page_text: Water may be supplied to the. interior of the casing in any suitable manner to
replace that lost (by, evaporation or otherwise) in the operation of the apparatus-
in the arrangement shown the water is supplied from above through the pipe T
to the annular water box formed in the bearing R and thence by the pipe T with
cock T at the lower end thereof through the funnel T2 and pipe T3 into the
lower part A of the casing.

V is draw-off tap by which the water in tank A can be changed when desired
for instance when it becomes thick with soot.
The spindle P is revolved in any suitable manner for instance by a motor pro-
vided for this purpose.
This apparatus can be applied to a locomotive (the apparatus being made. if
desired only 60 centimetres diameter) and can be operated by power transmitted
from the locomotive. When fixing the apparatus to a locomotive the mouth of
the chimney must be closed by a suitable cover provision being of course made
for the escape of steam.
The smoke is drawn in by the fan 0 (by which the water is agitated) and washed
and is then drawn up by the fan N which ejects it through the outlet pipe. M
which latter is directed in the opposite way to that in which the locomotive runs
and advantageously directed towards the ground.
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
-
1. The hereinbefore-described method of washing smoke or products of com-
bustion (from boiler or other furnaces) by forcing same by centrifugal force into
or against water which is simultaneously agitated-substantially in the manner
hereinbefore set forth.
2. The herein described apparatus for washing smoke, etc. constructed combined
and arranged to act substantially in the manner and for the purposes herein
before described with reference-to-the-drawings.
