Improvements in and relating to Oil Separators and Steam Dryers.
I, WILLIAM JAMES BAKER, of Peasholme House, Scarborough, in the County
of York, Consulting 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:-
-
This invention relates to improvements in and relating to oil separators and
steam dryers.
According to this invention I provide a shell or casing having a steam inlet,
a steam outlet, and a water well at the lower part thereof, the steam inlet open-
ing into an expansion chamber from the bottom of which tubes extend nearly
to the surface of the water in the bottom of the shell which also contains a number
of upright plates provided with baffles. An overflow pipe for the water in the
well is also provided.
The steam enters the expansion chamber through the steam inlet, where a
certain quantity of the grease and oil is deposited, and then flows down the tubes
leading to the bottom of the said chamber on to the surface of the water in the
bottom of the shell after which it is deflected up and flows through the shell
in a zig-zag path until it reaches the outlet, the remaining grease and oil being
deposited upon the surface of the water and upon the baffles.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure 1 is a sectional elevation of an oil separator made according to the
invention; and
Figure 2 is a plan thereof with the cover removed.
a is the outer shell which may be of any suitable shape, such as cylindrical,
as shewn in the drawing, b is the inlet branch through which the steam to be
purified enters the shell and c is the outlet branch for the purified steam
from the said shell, d is the water in the bottom of the shell and e is the overflow
pipe.
f is the expansion chamber which is formed or fixed in the shell a opposite the
inlet pipe b which opens into the same. g, g are the tubes extending from the
bottom of the said expansion chamber f nearly to the surface of the water < in
the bottom or well of the shell a, and h, are the vertical plates secured in the
shell and having the baffles i, i, the said plates being secured alternately to opposite
sides of the shell so that the steam is forced to take a circuitous path; to further
baffle and extract grease from the steam the baffles i, i are arranged and fixed at an
angle to the plates h, has clearly shewn in Figure 2.
With this arrangement the greasy steam enters the separator through the inlet
branch b, immediately expands in the chamber f and deposits a large portion
of its grease therein which said grease and separated water as well as the steam
pass down the pipes 9, 9, the steam impinging upon the surface of the water d
in the well whereby further portions of grease are attracted and separated. The
steam is then deflected up and passes between the parallel plates h, h and the
grease is deposited in the angles formed between the said plates and the baffles i, i,

by the overflow pipe e. The purified and dried steam escapes through the outlet
branch c.
:>
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. Apparatus for separating oil and grease from, and drying, steam, such
apparatus comprising an outer shell of suitable shape having inlet and outlet
branches, the former of which opens into an expansion chamber from which tubes
extend vertically downwards, the said shell also containing upright plates carry-
ing baffles arranged at an angle thereto, substantially as, and for the purpose,
herein before described.
2. The manufacture and use of the apparatus for drying, and for separating
oil and grease from steam, constructed substantially as herein before described
and illustrated in the accompanying drawing.
