Improvements in or connected with the Destruction of Distillery
Refuse.
We, DAVID BRUCE CUMMING, of 16, Brunswick Street, Liverpool, in the County
of Lancaster, Consulting Engineer, and JoHN HAMILTON FULLARTON, D.Sc., of 10,
Octavia Cottage, Greenock, in the County of Renfrew, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to the destruction of liquid refuse of distilleries;
and has mainly for its object to effect this end economically.
According to this invention, the liquid is first ridded of the solid matters in
it, in suspension, by passing it through filters or centrifugal separators. Some
of this liquid is then utilized as feed water for the steam generator used on the
premises of the distillery; and when the density of the liquid in the boilers
becomes, such that it contains 15 ounces of foreign matters in solution to the
gallon, a part of it is blown off into special evaporators or small boilers heated
by the escaping gases from the fires under the stills. The other portion of the
original refuse liquid, which has not been delivered into the steam generators, is
also pumped into the said evaporators or small boilers, and the whole is evaporated
down to the consistency of syrup, which is drawn off through a suitable cock.
The evaporators or small boilers are then again charged.
By the above mentioned treatment and method, it will be seen that the object
is very economically effected, the liquid refuse being destroyed with little or no
expense.

Improvements in or connected with the Destruction of Distillery
Refuse.

of Lancaster, Consulting Engineer, and JOIN HAMILTON FULLARTON, of 10,
Octavia Cottage. Greenock, in the County of Renfrew, Doctor of Science, do

page_text: 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 has reference to the destruction of liquid refuse of distilleries;
and has mainly for its object to effect this end economically.
According to this invention, the liquid is first ridded of the solid matters in
it, in suspension, by passing it through centrifugal separators; and is then
delivered into special evaporators or small boilers heated by the escaping gases
from the fires under the stills or boilers of the distillery, and is evaporated down
to the consistency of syrup, which is drawn off through a suitable cock. The
evaporators or small boilers are then again charged.
By the above mentioned treatment and method, it will be seen that the object
is very economically effected, the liquid, refuse being destroyed with little or no
expense.
The drawing hereto annexed illustrates this invention, shewing it in general
sectional plan.
Referring to the drawing, a may be taken to represent the flue by which the
waste or residual heating gases are conveyed away from stills, boilers, or heating
apparatus of the distillery; b represents the chimney stalk through which these
gases are passed; and c is the common flue leading from the separate flues a to b.
In these parts c, the evaporators or small generators d are disposed, in which
the refuse material is evaporated down.
e represents a tank into which the refuse liquor is first introduced; f is a
donkey pump adapted to feed the liquid from the store tank
e to the
evaporators; and h is a centrifugal separator on the pipe e¹ leading to the
pump, for removing from the liquid, matters in suspension in it.
i represents a feed heater, by which the refuse liquid supplied to the
evaporators d is heated on its way, and as it is delivered by the pump f; the
liquid being heated by the vapour from the evaporators d, conveyed by the
pipes d', and passed through a heating coil in . The hot feed passes from
the heater i to the evaporators, by pipes k, and past a check valve k¹ on d. In
the case shewn, also the donkey pump f is driven by steam from the evaporators
or small boilers d, steam being conveyed by the pipe to the cylinder; and the
steam cylinder of the pump may also be supplied with steam through the pipe m
from the main boiler, so that it can be driven by either when required.
o represents a pipe, and o¹ a spray nozzle. Through this pipe and spraying
nozzle the heavier and concentrated portions of the boilers d may be blown down,
and discharged into the chimney stalk; but it is to be stated that this spraying
of the refuse forms no part of the present invention and patent.
The heating surface of the evaporators d may consist of tubes passing through
it from end to end, or of any other suitable form.
With regard to the general action, the liquid distillery refuse supplied to the
tank e first passes to the centrifugal separator h, by which it is ridded of solid or
suspended matters; and it is then drawn into the pump f, and forced into the
steam heater i; and thence by the pipe k, past the check valve ¹, into the
small steam generators or evaporators d, in the flues c, wherein the waste heating
gases passing through them from the works, boilers, heating apparatus, or
furnaces, to the chimney stalk b, evaporates the liquid.
In the feed heater i, the liquor supplied to the evaporators d is heated up by
the steam generated in the evaporators themselves. By this means, the amount
of refuse which can be got rid of, is increased. When the boilers or evaporators d
contain a considerable quantity of dense or heavy or concentrated matters, it is
blown out of the boiler bottoms through the pipes o. In the drawing, the pipe
is shewn entered into the chimney stalk; and in such cases, it is sprayed into the
uprising gases into the chimney stalk b.
The liquors requiring to be destroyed in distilleries are mostly spent-lees,
burnt ale, washings of the vessels, and the like.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. The destruction of distillery liquid refuse, by the evaporation of such
liquors in evaporators or small boilers, disposed in the flues of the distillery
plant conveying the waste hot gases from the heating apparatus thereof to the
chimney stalk; substantially as in the manner herein set forth.
2. In the destruction of distillery liquid refuse, ridding the liquid of solid or
non-liquid matters by means of a centrifugal separating machine; supplying
said liquid to, and concentrating and evaporating it in, small boilers or evaporators
in the waste gas flues of the distillery heating apparatus or furnaces; and then
blowing down"
the syrupy or analogous fluid formed therein, from same;
substantially as herein set forth.
