New or Improved Water Heating and Purifying Apparatus:
Year: 1898

page_text: New or Improved Water Heating and Purifying Apparatus:
I, WARWICK JOSEPH WRIGHT, of Broad Sanctuary Chambers, Westminster, in
the County of London, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention has for its object apparatus wherein water may be heated by
exhaust or live steam and purified by treatment with suitable reagents and filtered.
Such apparatus I construct of three vessels of cylindrical or other shape. In
the first of these the steam to be utilized is first cleansed of grease or other matter
carried by it, and in the second the cleansed steam is brought in contact with
the water to be treated and the latter mixed with suitable reagents. The third
vessel is divided horizontally into two compartments, the larger of which forms a
settling tank and the smaller a filtering chamber.
The grease separating vessel is connected at its upper end on one side to the
steam supply pipe and at its opposite side to the lower portion of the heating
and mixing chamber. Between this inlet and outlet is arranged a central division
plate perforated in its lower portion, and which causes the steam passing through
the vessel to travel first downwards, then through the perforated portion of said
division plate, and then upwards. In each or either of the divisions are arranged
a number of horizontally projecting ledges extending completely round said
chamber or chambers, against which the steam in its travel strikes, and is so
given additional circulation.
The heating and mixing vessel is provided at its upper end with an outlet
for the unused steam and has fixed in it at a point above the steam inlet, a
horizontal tray, into which the reagents and the water to be treated are fed, the
latter through a pipe governed by a valve actuated by a float situated in the
settling division of the settling and filtering vessel.
The reagent is pumped in by an auxiliary pump drum from the pump which
draws the treated water from the filter, so that it always delivers an amount of
reagent in proportion to the water taken from the apparatus. From this trough
the water overflows and coming in direct contact with the ascending steam, is
heated. It then passes through a suitable pipe from the bottom of the mixing
and heating vessel to the bottom of the settling division of the settling and filter-
ing chamber and ascending in this overflows through a connecting pipe into one
side of the filtering chamber. In this chamber between the inlet and outlet
thereof is arranged a suitable filter bed between perforated plates or the like,
and through this the water overflowing from the settling division must pass before
escaping from the apparatus.

page_text: Suitable outlets are provided in the different parts of the apparatus to permit
of these being cleaned.

New or improved water Heating and Furying Apparatus.
I, WARWICK JOSEPH WRIGHT, of Broad Sanctuary Chambers, Westminster, in
the County of London, 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:―
My invention has for its object apparatus wherein water may be heated by
exhaust or live steam and purified by treatment with suitable reagents and filtered.
Such apparatus I construct of three vessels of cylindrical or other shape. In
the first of these the steam to be utilized is first cleansed of grease or other matter
carried by it, and in the second the cleansed steam is brought in contact with
the water to be treated and the latter mixed with suitable reagents. The third
vessel is divided horizontally into two compartments, the larger of which forms a
settling tank and the smaller a filtering chamber.
The grease separating vessel is connected at its upper end on one side to the
steam supply pipe and at its opposite side to the lower portion of the heating
and mixing chamber. Between this inlet and outlet is arranged a central division
plate perforated in its lower portion and which causes the steam passing through
the vessel to travel first downwards, then through the perforated portion of said
division plate, and then upwards. In each or either of the divisions are arranged
a number of horizontally projecting ledges extending completely round said
chamber or chambers, against which the steam in its travel strikes to arrest
impurities which may be in the steam.
The heating and mixing vessel is provided at its upper end with an outlet
for the unused steam and has fixed in it at a point above the steam inlet a
horizontal tray, into which the reagents and the water to be treated are fed, the
latter through a pipe governed by a valve actuated by a float situated in the
settling division of the settling and filtering vessel.
The reagent is pumped in by an auxiliary pump driven from the pump which
draws the treated water from the filter, so that it always delivers an amount of
reagents in proportion to the water taken from the apparatus. From this trough
the water overflows and coming in direct contact with the ascending steam is
heated. It then passes through a suitable pipe from the bottom of the mixing
and heating vessel to the bottom of the settling division of the settling and filter-
ing chamber and ascending in this overflows through a connecting pipe into one
side of the filtering chamber. In this chamber between the inlet and outlet
thereof is arranged a suitable filter bed between perforated plates or the like,
and through this the water overflowing from the settling division must pass before
escaping from the apparatus.
The accompanying drawings show a sectional elevation, Fig. 1, an elevation,
Fig. 2, and a plan Fig. 3, of apparatus as above described, and which will be
better understood with reference thereto.
As shown the apparatus consists of a settling and filtering tank a, a grease-

page_text: separating tank b, and a mixing tank c, the latter two or which may be either
attached to the first mentioned or otherwise conveniently arranged.
The tank a is divided by a horizontal division plate into two portions, the
upper forming a settling chamber and the lower à filtering chamber, and these
communicate with one another, through pipe e, so that the water as it rises in
the settling chamber may escape into the filtering chamber in which a filter bed
hold between perforated plates is arranged between the inlet and outlet thereof.
Above this tank a is situated the mixing chamber c the interior of which is in
communication with the lower portion of the mixing chamber of tank a through
a pipe such as f. This tank c has fitted in it a tray g into which the water to
be treated is fed by a supply pipe h governed by a float valve j having the float
thereof situated in the settling chamber of the tank a and into this tray is also
fed the reagents through a pipe k the supply being effected and governed by the
pump utilized for drawing the water from the filtering chamber of the tank a
and it will be thus seen that the reagents are so mixed with the water before the
latter overflows from the tray and falling in a spray to the bottom of the tank c
meeting the steam supply in its passage.
The steam supply enters the tank cat and that unused escapes through an
opening in the upper part of said tank at m. Before entering such tank, how-
ever, the steam passes through the grease-separating tank & fitted with a division
plate arranged between the inlet n and outlet o and perforated at its lower end,
and with projecting ridges p₁ against which the steain in its travel strikes.
Suitable outlets q are provided in the different parts of the apparatus to permit
of these being cleansed.
P
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) Water heating and purifying apparatus consisting of a mixing and heating
vessel a settling and filtering vessel and grease-separating vessel constructed
communicating and operating substantially as described and illustrated by the
accompanying drawings.
(2) In water heating and purifying apparatus a heating and mixing chamber
fitted with a tray into which the water to be treated and the reagent may be fed
and when mixed will overflow and in descending meet the steam on its upward
passage substantially as described and illustrated by the accompanying drawings.
(3) In water heating and purifying apparatus a grease-separator formed of a
chamber fitted with a division plate perforated at its lower end and arranged
between the inlet and outlet of such chamber and with internal annular pro-
jecting ledges substantially as and for the purpose described and illustrated by
the accompanying drawings.
