in separators
Year: 1899

page_text: EDWARD HENRY BECKETT, of 35, Queen Victoria Street, London, E.C., Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in oil separators. That is to
say, in apparatus for automatically separating the oil or grease, or lubricant,
from steam or vapour passing through pipes, such as the exhaust steam from
steam engines which is well known to contain portions of oil or grease or other
lubricant used in the steam cylinder. The object of the invention is to purify
the steam or vapour in such a way as the steam or vapour, after being condensed
may be used for other purposes in which the presence of foreign substances
might prove deleterious. It has been found, that by inserting a vessel, in which
a check, or baffle is placed, in a run of pipes through which steam passes, so as
to arrest the flow; that grease or oil contained in the steam, is to a large extent
separated and retained. I therefore construct my vessel or oil separator in
such a way as I describe hereafter in order to complete as far as possible the
separation of oil or grease the separation of oil or grease from the steam con-
veyed.
My vessel or oil separator is constructed mainly of a tank of iron or steel or
other metal with an inlet and outlet branches, to connect to steam pipes or ex-
haust mains. Inside the tank or vessel I place a vertical convex curved or angular
deflector or baffle plate against which the substance primarily impinges and from
which it is guided on to two concave circular or angular deflectors or baffles
which arrests its passage. Hence passing under the secondary baffle and rising
in a zig-zag course guided by horizontal baffles constructed of wood or metal to
the outlet. The oil or grease &t. is retained by the portions as above described,
and deposited in the lower portion of the vessel from which it is drawn off
through the pipe provided. If the steam pipe or exhaust main be open to atmo-
sphere or other pressure, the oil or grease &. is drawn off by gravity but should
the steam or exhaust main be under vacuum, a pump must be employed.

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 apparatus for separating oil, grease and other impuri-
ties from exhaust steam and thus rendering the said exhaust steam, when con-
densed, more suitable for boiler feed.
The apparatus employed in carrying out this invention consists of a shell of
wrought or cast iron or of other suitable material and preferably cylindrical in
shape, with branches in the sides for the inlet and outlet of the exhaust steam.
from the steam engine.
The interior of this shell is fitted with baffles, or obstructions to the free flow
of the steam, arranged as shown on the drawing and hereinafter described.
The drawing accompanying this specification consists of Fig. I, which repre-
sents a sectional elevation and Fig. II which represents a sectional plan.
The two branches referred to are marked respectively inlet A and outlet C,
and the direction of passage is denoted by the arrows.
The internal baffles are marked respectively B, B1, B2.
The method of separation is as follows:
The steam enters the inlet branch A and strikes or impinges against the
baffle plate B which is convex in shape and diverts the direction of flow against
the two sides where it is caught by the baffle 131 which consists of two concave
plates (or one plate bent in similar form as shown) and guided on to the back
or concave surface of the baffle plate B.
The plate B is carried down to the bottom of shell so that all the steam passes
by the sides only. The plate B¹ is carried down nearly to the bottom but arranged
so that all the steam passes under.
After passing under the plate B' the direction of flow is checked by the baffle
plates B2 arranged as shown in the drawing.
The baffle plates may be of iron or other metal or of wood.
The oil or grease or other foreign substance in the exhaust steam is arrested
in the surfaces of the several baffles during the passage of the steam and from
these it drips or runs down into the bottom of the shell or body from whence
it is drained away through the drain pipe marked D.
In the case of a condensing engine this drain must be connected to a small
pump but in the case of a high pressure engine a simple drain cock only is neces-
sary.
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
1. The apparatus for separating grease or other foreign matter from steam
consisting of shell casing of iron or other suitable material fitted with a series
of baffles combined and arranged as described in this specification and the accom-
panying drawings.
