Improvements in and relating to Vapor Condensers, and Apparatus
for Destroying Noxious Fumes, Recovering By-products from
Distillation, and like purposes.
We, SAMUEL GUEST MERRICK, Gentleman, and HENRY LUCIUS WASHBURN,
Lawyer, citizens of the United States of America, residing respectively at
82 Forrest Building in the City and County of Philadelphia and State of
Pennsylvania, and at 280 St. Nicholas Street, in the City, County and State of
New York, United States of America, 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 :—
Figure 1 of the drawings illustrates in end elevation a retort for the production
of gases, and in cross section the condensing apparatus of this invention.
Figure 2 is a central longitudinal section of the condenser, with some parts in
elevation.
Figure 3 is a broken view of a coil pipe, and
Figure 4, a broken view of such a coil inclosed in a cylindrical casing.
The drawings are intended merely as a guide in the construction of the device,
and do not necessarily show the proportions.
A, indicates a pipe from a furnace, or it might be from a retort, or from any
place where noxious gases, vapors containing residual products, or other vapors
desirable to condense, are generated or stored.
B, indicates a casing or tank into which gases are conducted. This tank has two
chambers, B' and B2, and divided from each other by a partition B³.
A shaft C, extends through the two compartments, being inclosed in stuffing
boxes C' in the walls, so as to make close joint. This shaft may be rotated by
power applied to pulley C², or in other suitable manner.
The shaft C is surrounded by coiled metallic pipes D, D, said coils being
supported on spiders D¹ or in other suitable manner, so that the rotation of shaft Č
rotates the coils, of which the shaft is the axis.
Each coil has a conical or enlarged mouth piece D³, which mouth piece is
inclined at the outer end, so that when the tank is filled with liquid, say about to
the dotted line, Figure 1, the mouths will be about parallel with the liquid at the
point of entry thereto.
The coils may be inclosed in a metallic casing E, or this casing may be merely a
collar E, at the place of passage through the partition, making a reasonably close
joint. The passage between the coils and shaft will also be closed in line with the
partition..
The vapors or gases will be drawn into the chamber B' by the rotation of the
coils, when arranged as in Figure 1. Or a fan blower F, may be placed inside or
outside the compartment B¹, to drive the gases toward the mouth of the coils.
When the tank is filled with liquid above the coils, and the coils are rotated as
indicated by the arrow, the mouths take in a quantity of gas, while passing above
the liquid. When the mouth is closed by entry into the liquid, this inclosed gas
or vapor will be compressed, and will be driven by the liquid along the coil, a
portion of the liquid following. The liquid in chamber B₁ should be preferably
above the body of the coil. The tendency of the coil will be to force the vapor
or gas and the liquid from the chamber B' to chamber B2.

page_text: Cocks or passages H, H, controllable from outside the tank, may regulate the
return of the liquid, from chamber B to chamber B'. A passage K governed by
a cock may permit the return of gas or vapor, and a pipe L may conduct the
uncondensed fumes, if any, away from the apparatus.
For condensing the fumes from some kinds of oil, the liquid used in the
chambers may be water. For condensing an acid gas, an alkaline liquid may be
used, and various liquid chemical reagents may be employed in various arts.
The apparatus gives a convenient means of bringing the fumes or vapors into
ultimate contact with the liquid under pressure.
In condensing vapors from the distillation of petroleum, the condensed
residuum has been found of sufficient value to pay the cost of condensation,
besides ridding the air of unwholesome vapors.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.
1. The rotating coils having enlarged mouths with inclined openings, arranged
with the ends of the coil in different compartments of the tank or chamber
containing liquid.
2. The tank having compartments and a rotating coil with the ends in the
different compartments, and passing through the partition with a close fit, and the
valves controlling the passage of liquid through the partition, so that the level
of the liquid in the different compartments can be controlled.
3. The liquid containing tank having compartments and a rotating coil with one
end in each compartment, and the blower near the mouth of the coils, and the
means for regulating the height of the liquid in the compartments.
Dated this Thirty-first day of December 1895.
