Improvements in Apparatus for Drying Purifying, Separating Oil or
Grease from and Condensing Steam, and for Heating and Purify-
ing Water for Boiler Feed and for other Manufacturing purposes.
I, WILLIAM HINCHLIFFE, of Ings Cottage, Denby Dale Road, Wakefield, in
the County of York, Engineer, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to apparatus for separating water from steam, for purify-
ing exhaust steam, of condensing and non-condensing engines, from dirt and
lubricating grease, and for utilizing the purified steam for the purposes of heating
and purifying water, and removing lime and other impurities therefrom previous
to such water being employed, or used for boiler feed or for manufacturing
purposes.
The apparatus employed for purifying steam consists of a steam tight shell or
hollow vessel, which may be formed rectangular or cylindrical which may herein
after be referred to as the purifier. The purifier internally is divided into two
chambers by fixing two division plates, baffles or bridges therein, for the purpose
of diverting, directing and controlling the steams course through the purifier.
The first baffle plate is fixed some distance from, but opposite to the steam inlet
and extends from the top of the purifier to some distance below the steam inlet,
the deflected steam passes under the lower edge of said plate into the adjoining
chamber. This baffle plate or deflector is of a concavo-convex form across its
perpendicular and may be set at a slight angle in relation to the steam inlet in
order to throttle and tend to keep the expanded steam in the first chamber. Its
lower edge is scrolled so as to form a gutter or grease receiving channel on the
steam side of said plate, the separated grease deposited on its face descending into
said channel and to convey the same to corresponding conducting channels formed
on each down side of this deflecting plate, to the bottom of the purifier, or to the
A second
surface of the water of condensation which may be on the said bottom.
baffle plate or bridge is fixed vertically from the bottom of the purifier and extends
to within a suitable distance from the top plate or cover of the purifier forming
a second chamber. Immediately behind or in close proximity thereto, a number
of grates are arranged at an angle to meet the out rushing steam. On the face of
these grates the bars or intervening ribs or partitions are of a channelled or gutter
form, and each rib in each grate is arranged to be opposite to the intervening
spaces, perforations, or apertures. The steams course on entry to the purifier is
downwards in the first chamber under the first baffle plate and upwards in the
second chamber and to pass in a horizontal line from the bridge to the delivery
pipe in a zig-zag direction through the intervening spaces of the grates, and the
particles of grease, dirt or water which appear in suspension are received on to
the said baffle-plate, and in the gutters formed on the faces of the grates and are
thus conducted by force of the steam to the bottom of the purifier. A pipe is
A pipe is fixed to the bottom
arranged at the side to carry off the greasy scum etc.
to drain the water of condensation away. Like grates may be applied in the

page_text: first chamber of the purifier, and the latter may be placed between the high
pressure cylinder of a condensing engine and its condenser or other convenient
position.
The purified steam is so diverted as to come in contact with the water to be
treated and is conducted to a feed water heater of a condenser form in order to heat
the water, and the more readily to conduce to separation or to bring into suspension
the mineral salts which may be in solution. The re-agent employed for the
purpose of effecting deposition is supplied along with the water or separately into
the water chamber which mingles with and so neutralizes the water.
The condenser may be of cylindrical or of a rectangular form and consists of a
water chamber, and a circular steam channel, the water and re-agent are fed
through the top or lid and fall on to a flat perforated plate which is arranged to
fit and rest on a circular lip, formed internally on the heater or condenser shell,
a circular perforated or annular ring is placed underneath this plate and a steam
channel is formed between the condenser shell and the outer periphery of the
perforated ring. As the steam is permitted to enter the said circular channel, it
passes through the perforations in the ring and is condensed by the falling water.
The water thus heated passes from the condenser and flows down a channel or
gutter to a pipe leading to the bottom of the settling tank. This water channel
may be set at an angle on the top of the settling tank or at a suitable elevation for
the water to flow from the condenser to the tank. The channel has a removable lid
for cleaning out purposes and a steam escape pipe may be placed thereon. A
series of plates may be placed vertically across the channel alternately from each
side arranged for to guide the down rushing water to pass alternately from one side
of the channel to the other, and round the alternate ends of the said plates, or
a series of V or angular shaped plates or projections may be placed centrally in
the channel with corresponding plates set at an angle towards the centre from the
sides behind the water on meeting the apex of the A shaped plate is divided
and turned to the sides and the plates projecting behind induce the treated water
to converge and meet in the centre of the channel after each operation. The course
of the water is zig-zag or contortionate thereby causing the re-agent employed
to become thoroughly mixed with the water and the particles in suspension.
Settling tanks of any convenient form and capacity may be employed, and may
be subdivided into any number of compartments, but an oblong and rectangular
tank containing three or four compartments is preferred. Each compartment is
connected to each other by a channel or by a syphon or conduit pipe arranged to
carry the water out of one compartment, from a point near its upper surface, to a
point in the adjoining compartment near its bottom. These conduit pipes or
channels may be arranged internally at right angles to the tank or on the outside
of the settling tank. Each compartment may have a flat bottom or be formed with
sloping sides or a false bottom may be formed therein, by placing plates against the
sides and sloping them towards the centre or towards the sludge-plug or pipe in
order to facilitate the removal of the sludge or other deposit.
In order to prevent loss of water during the operation of and removal of the
sludge there is applied a trap door which may be made in one or more separate
parts and may be hinged to the sides of the compartment the trap door may rest on
a liner or cross bar or other like form of support at some desirable distance from
the bottom thus forming a sludge chamber below the doors. These trap doors are
intended to be closed only during the operation of letting off of the sludge.
Each compartment is provided with a sludge cock or plug controlled by rod and
hand lever and an overflow pipe and a perforated steam pipe, or a steam pipe
having an arrangement of jets projecting therefrom may be carried along the sides
of cach compartment the said projecting jets are set at an angle pointing in the
direction of the orifice of the overflow pipe, and arranged for the purpose of blowing
the scum which may form on the surface of the water through and down the
overflow pipe.
Any so formed scum or sediment may be conveyed by pipe or channel from

page_text: the tank to a filter bed composed of small coke or engine ashes or other suitable
filtering media.
For the purpose of feeding the re-agent against steam pressure, over the water
chamber a receiver is formed for the feed water to enter, which contains an or
syphon shaped pipe one end of this syphon pipe is fixed into the lid of the
water chamber, and the re-agent is then permitted to flow into the receiver by
gravitation or under pressure.
The steam escaping after, or during the process of heating of the water may pass
through pipes or coils placed in a reservoir or tank in which the water to be treated
may pass through to the heater in order that the waste heat from the steam may be
further absorbed etc.
In heating of the water a series of pipes of S or bend form connected at their
ends to two water reservoirs may be placed in the flue between the boiler and
chimney stack to be heated by the waste gases of combustion. The water to pass
through these pipes to the water inlet of the apparatus, or the apparatus may be
connected to and in conjunction with a
66 Green's Economiser" or other form of
water heater.

Improvements in Apparatus for Drying, Purifying, Separating Oil or
Grease from and Condensing Steam, and for Heating and Purify-
ing Water for Boiler Feed and for other Manufacturing purposes.
I, WILLIAM HINCHLIFFE, of Ings Cottage, Denby Dale Road, Wakefield, in
the County of York, 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 apparatus for separating grease and
fat from and drying or condensing steam, and for heating or purifying water or
trade effluents and removing impurities therefrom. The invention consists of
apparatus for purposes aforesaid and each apparatus may be used independently
for its own purpose or the three may be used in combination as for instance when
employed in connection with a steam engine where it is desired to purify the
exhaust steam and remove therefrom the dirt and lubricating grease and utilizing
the purified steam for the purpose of heating water and amalgamating therewith
a re-agent or disinfecting body, after which the water may be passed through
settling tanks when solid bodies or particles in suspension are retained and pure
water alone escapes.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a sectional side elevation of the part of the apparatus specially
designed for removal of the lubricating grease and dirt from steam, but applicable
also for drying steam.
Fig. 2 is a sectional plan view of Fig. 1.
Fig. 3 is a sectional side elevation of the apparatus into which the purified
steam is passed for heating and purifying water, and which serves for condensing
the steam

page_text: g. is a horizontal sectional view of Figs. 3 and 4.
Fig. 6 is a plan view of a series of settling tanks designed for use in combination
with the purifying apparatus.
Fig. 7 is a sectional elevation of Fig. 6.
Fig. 8 is an end sectional view of one of the settling tanks.
The apparatus employed for purifying and drying steam and removing grease
and oil therefrom consists of a steam tight shell or hollow vessel 1 (see Figs.
and 2) which may be formed rectangular or cylindrical and which is hereinafter
referred to as the purifier. The purifier 1 internally is divided into two chambers
by fixing two division plates, baffles or bridges therein, for the purpose of diverting,
directing, and controlling the steams course through the purifier. The first baffle
plate 2 is fixed some distance from, but opposite to the steam inlet 3 and extends
from the top of the purifier 1 to some distance below the steam inlet 3 and the
deflected steam passes under the lower edge of said plate 3 into the adjoining
chamber. The baffle plate or deflector 2 is of a concavo-convex form across its
perpendicular and is set at a slight angle in relation to the steam inlet 3 in order
to throttle and tend to keep the expanded steam in the first chamber. The lower
edge of the plate 2 is scrolled so as to form a gutter or grease receiving channel 4
on the steam side of said plate 2, the separated grease deposited on its face descending
into said channel 4 which conveys the same to corresponding conducting
channels 5, 5 formed on each down side of this deflecting plate 2 to the bottom of
the purifer 1 or to the surface of the water of condensation which may be on the
said bottom. A second baffle plate or bridge 6 is fixed vertically to the bottom
of the purifier 1 and extends to within a short distance from the top plate or
cover of the purifier 1 forming a second chamber. Immediately behind or in close
proximity to the plate or bridge 6 are a number of grates 7 arranged at an angle
to meet the out rushing steam. On the face of these grates 7 the bars or interven-
ing ribs or partitions 8, 8 are of a channelled or gutter form (see Fig. 2) and each
rib 8 in each grate 7 is arranged to be opposite to the intervening spaces,
perforations, or apertures. The steams course on entry to the purifier 1 is down-
wards in the first chamber under the first baffle plate 2, and upwards in the second
chamber, and to pass in a horizontal line from the bridge 6 to the delivery pipe 9
in a zig-zag direction through the intervening spaces of the grates 7, 7, and the
particles of grease, dirt, or water which appear in suspension are received on to the
said baffle plate 2, and in the gutters 8, 8 formed on the faces of the grates 7, 7
and are thus conducted by force of the steam to the bottom of the purifier 1. A
pipe or outlet 10 is arranged at the side of the purifier 1 to carry off the greasy
scum and dirt, and a pipe 11 is fixed to the bottom to drain the water of condensa-
tion away.
Grates such as 7, 7 may be applied in the first chamber of the
purifier I and the latter may, be placed between the high pressure cylinder of a
condensing engine and its condenser or other convenient position.
The purified steam is so diverted as to come in contact with the water to be
treated and is conducted from the outlet 9 to a feed water heater (see Sheet 2) of a
condenser form in order to heat the water, and the more readily to conduce to
separation or to bring into suspension the mineral salts which may be in solution.
The re-agent employed for the purpose of effecting deposition is supplied along
with the water or separately into the water chamber which mingles with and so
neutralizes the water.
The condenser 13 may be of cylindrical or of a rectangular form and consists of
a water chamber 14 and a circular steam channel 15. The water and re-agent are
fed through the top or lid 15" and fall on to a flat perforated plate 16 which is
arranged to fit and rest on a circular perforated annular ring 18 resting on a
lip 17 formed internally on the heater or condenser shell, and a steam channel 15
is formed between the condenser shell and the outer periphery of the perforated
ring 18.
As the steam is permitted to enter the said circular channel 15 it passes
through the perforations in the ring 18 and is condensed by the falling water.
The water thus heated passes from the condenser and flows down a channel or

page_text: gutter 20 to a pipe 21 leading near to the bottom of the settling tank 22. This
water channel may be set at an angle (see Fig. 3) on the top of the settling tank 22,
or at a suitable elevation for the water to flow from the condenser to the tank.
The channel 20 has a removable lid 23 for cleaning out purposes and a steam
escape pipe may be placed thereon. A series of baffle or diverting plates 24
may be placed vertically across the channel 20 alternately from each side arranged
to guide the down-rushing water to pass alternately from one side of the channel
to the other, and round the alternate ends of the said plates 24, or a series of V or
angular shaped plates or projections may be placed centrally in the channel 20
with corresponding plates set at an angle towards the centre from the sides behind.
The water on meeting the apex of the V shaped plate is divided and turned to the
sides and the plates projecting behind induce the treated water to converge and
meet in the centre of the channel after each operation. The course of the water is
zig-zag or contortionate thereby causing the re-agent employed to become
thoroughly mixed with the water and the particles in suspension.
Settling tanks 22, 22, 22 of any convenient form and capacity may be employed
and may be subdivided into any number of compartments but an oblong and
rectangular tank 22 containing three or four compartments is preferred. Each
compartment is connected to the succeeding one by a channel, or by a syphon or
conduit pipe 25 arranged to carry the water out of one compartment from a
point near its upper surface to a point in the adjoining compartment near its bottom.
These conduit pipes or channels 25 may be arranged internally at right angles to
the bottom of the tank, or on the outside of the settling tank. Each compartment
may have a flat bottom, or be formed with sloping sides as shewn, or a false
bottom may be formed therein by placing plates against the sides and sloping
them towards the centre or towards the sludge plug or pipe 26 in order to
facilitate the removal of the sludge or other deposit.
In order to prevent loss of water during the operation of and removal of the
sludge there is applied to each compartment a trap door 27 hinged to the sides of
the compartment and when closed resting on a liner or other support at some
desirable distance from the bottom, thus forming a sludge chamber below the
doors. These trap doors 27 are intended to be closed only during the operation of
letting off the sludge.
Each compartment is provided with a sludge cock or plug 26 controlled by
lever 25, rod 27, and hand lever 29, and an overflow pipe 30, and a perforated
steam pipe 31 or a steam pipe having an arrangement of jets projecting therefrom
may be carried along the sides of each compartment, the said projecting jets are
set at an angle pointing in the direction of the orifice of the overflow pipe 30
and arranged for the purpose of blowing the scum which may form on the surface
of the water through and down the overflow pipe 30. Any so formed scum or
sediment may be conveyed by pipe or channel from the tank to a filter bed
composed of small coke or engine ashes or other suitable filtering media, (or into a
series of settling tanks as illustrated by Figs. 6, 7 and 8).
For the purpose of feeding the re-agent against steam pressure I place (see
Fig. 4) near the water chamber 14 a receiver 31 for the feed water to enter
which contains a nor syphon shaped pipe 32 one end of which syphon pipe 32
is fixed into the lid of the water chamber 14 and the re-agent is then permitted to
flow into the receiver by gravitation, or under pressure.
When the settling tanks (see Sheet 3) are employed the effluent or water to be
purified passes into the tank 33 where it may be mixed with a re-agent or
disinfectant by means of the agitators 34, 34 and then flow along the sloping
channel 35 where it follows a zig-zag course owing to the baffle plates 36 and passes
into the settling tank 37 where the solid matters are precipitated and the water
flows over the top of the divisional plate or wall 38 by way of the conduit 39 into
the next tank, and so on through the series, the solid matter being precipitated in
each tank until thoroughly purified. The sludge or solid matter which collects
at the bottom of each tank can be removed by a pipe 40 (see Fig. 8) through which

page_text: it is forced by the weight of water in the tank, the pipe 40 being normally closed
by a valve or door.
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 general construction, arrangement, and combination of parts constituting
the improved apparatus as and for the purpose herein described and substantially
