QWLILSB ARTHUR FAGET, OF SAN FRANCISCO, CALIFORNIA.

WATER-DISTILLATION SYSTEM.

To all whom it may concern:

'Be it known that I, ARTHUR FAGET, a

I citizen ofthe United States. residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful lVater-Distillation System, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and'use the same.

This invention relates to a distillation system for ice plants, and its object is to .produce considerably less than one hundred tons, and to make up the extra amount, additional water must be distilled.

The object of this invention is to make use of the great amount of heat in the steam passing from the distillation apparatus, and

from the engine, to reduce to the smallest degree the heat necessary to evaporate the desired quantity of water.

A. further object of the invention is to reduce the condensation of steam at the exhaust steam, but in the system here employed, the heat units are not wasted since a greater expansion can be secured. in the engine, and the quantity of water at exhaust opening is reduced, thus reducing the quan tity of oil emulsion from the oil separator from 10 to 25%, The feed water is also heated to a considerable extent, first in the Specification of Letters Patent.

Application filed January 17, 1910.

Patented Sept. 27, 19i. Serial No. 538,511.

evaporator following the oil separator and, second, in the heater between the feed pump and the boiler.

The drawing is a diagram of such a distillation system, the same numeral representing the same portion throughout.

The numeral 1 represents a boiler, which may be of any desired type, said boiler having a superheating' attachment 2. Connected with the boiler is a pipe 8 having a.

branch 4 and a branch 5, each of the latter being provided with valves.

The numeral 6 represents a simple engine having a steam jacket 7. Leading from the engine is the usual exhaust pipe 8, connected with the heating coils of the water evaporator 9, said coils leading through the pipe 10 to the condenser chamber 11. This water evaporator has a supply pipe 12 and has a pipe 13 wherebythe steam produced in the evaporator .will be drawn into the condenser chamber 11. The condenser is maintained at the desired vacuum by means of the pump 14,- which latter is connected to the condenser by means of a pipe 15. The condenser is so situated that any Water collecting therein will run into a vacuum reboiler 16 through a pipe 17, and connected with the top of the reboiler and condenser chamber is a pressure equalizing pipe 18. The

superheated steam is led through the pipe 5 to the steam jacket 7, and from there through the pipe 19 into the feed water heater 20, and from the latter through a pipe 21 to the coils Within the vacuum rcoiler 16. The feed water is pumped into the boiler from the pump 22 through pipes 23 and 24. The pipe 21 terminates in the vacuum reboiler 16, and the exhaust pipes S and 10 terminate in the condenser chamher, after passing through the evaporator 9. The water is drawn from the vacuum reboiler 16 through a pipe 25 to a suitable storage receptacle, not shown.

The result of the construction shown will be, first: the economical use of the steam operating the engine 6 by'reason of the reduction in cylinder condensation therein due to operation at a slightly higher temperature; second: the evaporation of a considerable quantity of water in the water evaporator by means of the exhauststeani from the engine 6; third: the heating of ti feed water by means of the steam fr steam jacket 7 on the engine 6; .fourtn. ti reboiling of the water in the reboiler 1'6 by means of the heat retained in the ste m from the steam acket T.

It will be observed that all of the avater leaving this plant passes out through the pipe 25, and will be at the temperature of steam under the absolute pressure produced by the vacuum pump 14.

It will be noted that the supply pump 22 is connected by means of a pipe 26, with the water heater evaporator 9, the object being to take all water into the plant through the pipe 12, and to initially heat the water used in the boiler 1 in two places: first, by means of the exhaust steam which heats it to a certain extent by reason of the connection with the condenser chamber 11 which evaporates a certain percentage thereof; second, this water heated substantially to the temperature of the water in the boiler by means of the steam escaping from the steam jacket 7. The valve on the pipe 5 will be left open, in order to keep the cylinder 6 at substantially the temperature of the boiler, while the valve in the pipe 19 will be regulated to permit the heater 20 to be kept as hot as may be desired, the valve in the pipe 21 determining the actual quantity of steam permitted to escape into the reboiler 16.

It will be understood by those skilled in the art that a suitable oil separator 8 should be interposed in the path of the exhaust from the steam engine, inorder that the water from the condenser may be kept free from oil; such additional quantity of water required for the ice-making plant will be allowed to distil by passing off around the steam jacket of the engine.

s The quantity of water allowed to distil through the pipe 21 varies with the engine construction, since with a wasteful engine, a great deal of water will be passed through the engine exhaust, while with a very economical engine a smaller quantity of water will be obtained at the exhaust of the engine, therefore, the most satisfactory condition is that one in whichthe largest proportion of the distilled waterrequired passes off through the pipe 21, instead of through the engine.
