PROVISIONAL SPECIFICATION.
Improved Apparatus for Evaporating and Distilling Liquids.
RICHARD HARBURN Engineer 2 Fern Avenue Southwick Sunderland do hereby
declare the nature of this invention to be as follows:-
An apparatus for evaporating and distilling liquids by the aid of steam in a
chamber or chambers the pressure of which is reduced to a practical degree below
atmospheric pressure. The said chamber or chambers having outlets to condenser
and to pump or pumps the duties of which are to carry away matters not intended
for evaporation.
The method by which the evaporation or distillation is conducted is as follows-
A valve or valves the outlet or outlets of which are so arranged as to mix the
steam and liquid or liquids as they enter evaporating chamber.
In this chamber are fitted suitable plates for intercepting matters not intended
for evaporation this matter being carried away by pump or pumps for that
purpose. The evaporated or distilled portion being carried to condenser by
connection for that purpose.

COMPLETE SPECIFICATION.
Improved Apparatus for Evaporating and Distilling Liquids.
RICHARD HARBURN 2 Fern Avenue Southwick Sunderland Durham Marine
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 :-
The object of my invention is to evaporate and distil liquids by the aid of steam
in a chamber or chambers in a manner herein described.
The pressure in the said chamber or chambers may be reduced to a practicable
degree below the atmospheric pressure, the said chamber or chambers having
outlets to a condenser or condensers and to pump or pumps, the duties of the pump
or pumps being to carry away matter not intended for evaporation or distillation,
and the outlet to the condenser or condensers being to carry away the evaporated
or distilled portion.
The method by which the evaporation or distillation is conducted is as
follows.-
The steam and liquid are admitted into a special mixing apparatus so arranged
that the steam comes in contact with the liquid or liquids immediately before they
enter the chamber which we call an evaporating chamber.
In the chamber or chambers are fitted (but in some cases these are not required)
suitable plates for intercepting matter not intended for evaporation or distillation,
these matters being carried away by the pump or pumps for that purpose. The
evaporated or distilled portion being carried to the condenser or condensers by
connection for that purpose.
In order that the principle may be fully understood the accompanying drawings
explain the nature of the invention the letters of reference indicating the same or
corresponding throughout all the figures.
A B Fig. 1 represents the shell of the evaporator.
C represents the outside case of mixing apparatus.

page_text: The baffle plates in the evaporating chamber do not fit so as to make a joint
with the chamber, but are placed to intercept the unevaporated matter and are
fixed for easy removal for cleaning when necessary.
The plates may or may not be perforated but as may be suitable for the purpose
required.
The principle of the invention may be applied to a variety of purposes such a
in the manufacture of sugar and for separating the salts and alkalis in chemical
manufacture and the purifying of sea water for use in marine engine boilers.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The construction and arrangement of an apparatus for the evaporation or
distillation of liquids substantially as herein described and illustrated.
2. The fixing on the said apparatus of a special form of mixer, substantially as
herein described and illustrated.
3. The special form of mixer herein described whereby the steam and liquid are
made to come into immediate contact and discharged in the form of a spray at high
temperature instead of being separated by coils as heretofore, substantially as
herein described and illustrated.
