Improvements in Apparatus for Separating Dust and the like from
Blast-furnace and other Gases.
I, ANTON HEBELKA, of 102, Mainzer Street, Coblenz, in the Province of the
Rhine, German Empire, Engineer, 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:―
:
Hitherto in furnace-gas-purifiers the separated dust and the gases remained
within the same chamber, therefore it often happened that the dust when falling
down, at the bottom of the chamber met the gas again and was withdrawn from
In apparatus where the gas stream is pressed in at the top of the
apparatus, the dust took the same way as the gas and only was separated at the
bottom of the chamber.
the same.
The object of the present application is to provide an apparatus in which the
dust and the gas take separate ways within the purifier so that it is impossible
that the dust once separated again unites with the inflowing gas.
My invention will be the better understood with reference to the accompany-
ing drawing, in which two different forms of construction of my improved purifier
are represented, and in which:

be purified enter the purifier at A and leave the same through the tube B at the

bottom of the chamber. The interior of the purifier is provided with
of deflector plates ab arranged in a certain angle to the side walls. Owing to
the gas flowing down more rapid than the dust particles, the latter fall upon the
deflector plates and from there through openings e into a channel formed by
intercalation of a wall s. The arrangement of this channel d has the advantage
that the dust falls down directly without being in danger to meet again the stream
of the purified gas.
Arrived at the bottom of the channel, the dust particles are removed by a valve
of suitable construction which opens either at certain predetermined intervals
or which allows a constant dropping out of the dust particles. The gas arrived
at the bottom of the purifier flows out through the pipe B.
In Fig. 2 a modified construction of my apparatus is represented. In this
apparatus it is altogether impossible that dust particles are withdrawn by the
gas stream passing around the different deflector plates. A dust channel is ar-
ranged on both sides of the chamber, and the dust particles accumulated upon
the deflector plates a and b directly fall into the dust channels & d' appertaining
to the different deflector plates and evidently it is quite impossible that the gas
stream withdraws some particles of the falling dust.
By means of my apparatus the blast furnace gases are purified very thoroughly,
it thereby being possible to effect the purifying with less apparatus than heretofore
necessary, which will be an important point in industry."
This fact is of great importance in case the blast-furnace-gases are employed
for generating power in motors.

page_text: Evidently the apparatus can be employed not only for purifying blast furnace-
gases but for purifying all gases laden with dust, shavings or the like.
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. In a purifier for dust laden gases, the combination with a circular chamber,
deflector plates a b arranged within said chamber in same direction and at a cer-
tain angle, a dust channel d formed by an interposed wall e, openings e provided
in the walls and effecting the communication between the interior of the cham-
ber and the dust-channel, the purifying gases entering through an opening A
at the top of the apparatus, and flowing out at the bottom, the dust being retained
by the deflector plates a 6 and falling into the dust channel, substantially and
for the purpose as set forth.
2. In a purifier for dust laden gases, the combination with a circular chamber,
deflector plates ab arranged crosswise to another, dust channels & and
formed
on both sides of the chamber by interposed walls 8, openings e provided within
the walls and effecting the communication between the interior of the chamber
and the dust channels d d', substantially and for the purpose as set forth.
Dated this 6th day of October 1899.
