WILLIAM K. srnvnus, OF MANSFIELD, oHIo,
FEED- WATER PURIFIER.
SPECIFICATION forming" part of Letters Patent No, 293,537, dated February 12, 1884.
Application filed August 3, 1883. (No model.)
To all whom it may concern.-
-Be it known that 1, WILLIAM ILSTEVENS, of Mansfield,- in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Feed-Water Purifiers, of which the following is a specification.
My invention relates to apparatus for heating and for removing the impurities from feedwater for steam-boilers; and it consists of certain devices for the heating and purifying of the water under pressure whilein transit from the feed-pump to the boiler, all of which will be fully described hereinafter.
' In the accompanying drawings, in which similar letters of reference indicate similar parts, Figure l is a front elevation of a steamboiler, showing my improvement attached thereto. Fig. 2 is a partial elevation and partialsection of the parts shown in Fig. 1. Fig, 3 is a plan of Figs. 1 and 2. Fig. 4 is a plan of the lead strainer; Fig. 5, a sectional eleva tion, and Fig. 6 a bottom plan, of the filterchamber.
A is a steam-boiler of any approved type; B B, steam-pipes leading from boiler A to precipitating-chambers O O, and provided, re spectively, with valves 1) b.
D is the line offeed-pipe through which the feed-water is delivered to the first precipitating-chamber, G.
c and o are headsto the precipitating-chambers 0G,where the condensation of the steam and heating of feed-water takes place.
0 is a bent pipe of relatively large diameter, connecting the bottom of chamber 6 with top or head 0' of chamber 0, (the chamber '0 being arranged relatively above chamber 0, in
order that the contents of the former may flow by gravity into the latter.)
E is a down-pipe, connecting, by means of pipe 0, the bottom of chamber 0 with thelower portion of filter-chamber F.
F is the filter-shell, mounted upon legs f within the chamber F, and provided with a perforated bottom, f, of wire-cloth.
l G is a mass of lump coke completely filling the filter-shell F, and surmounted bya heavy perforated disk of lead, H.
F is the lid or cover of filter-chamber F, which is hinged and secured to flange of chamber by means of bolts and nuts, in the usual manner. The covers 0 c of precipitatingchambers O O are also hinged, as shown in Fig. 2,,and secured to the flanges of the respective chambers by bolts and nuts, in the manner customary with work of this character.
D is a continuation of the feed-pipe, connecting the upper part of filter-chamber with the lower part of the boiler A, and provided with a valve, (1.
6 is the blow-out pipe, controlled by valve 6 by means of which the filter-chamber F may be purged of the heavy residuum.
The opei ation of the apparatus is as follows: The feed-pipe D, precipitating-chambers O G, down'pipe E, pipe 6, filterchamber F, and pipe D being full of water at boiler-pressure, and intransit toward the boiler by the impulse of any approved form of feed-pump, steam is admitted from the boiler A through pipe B into chamber G, and by pipe B into chamber 0. 'The live steam, flowing into the precipitating-chambers, heat-s the feed-water to any desired temperature within the corresponding temperature of the steam at boilerpressure, and precipitates upon the walls and bottom of these chambers the impuritiesas carbonate of lime'in solution in the water. The water, freed from the most objectionable salt in solution, passes downward from the lower precipitatingchamber,G, through pipe E, and. thence into the filtering-chamber F by means of connecting-piper, thence upwardly through the wire-gauze strainer f, coke G, and perforated lead disk H, and finally through feedpipe D to the boiler A. The passage of the water upward through the filtering-chamber F F removes all the heavy matter in sus pension and delivers it to the boiler practi cally free from any injurious impurities.
I am aware that feed-water heaters and purifiers which perform the triple ofiice of removing the principal salts in solution, filtering from the water the matter in mechanical suspension, and finally heating the water approximately to the boiling-point are not new, and that my invention is limited to the devices substantially as shown and described. The amount of live steam requisite for the precipitating of the salts in solution is Sllffichamber F, containing the shell F, providedwith the perforated bottomf, perforated lead I 5 disk H, and intermediate filtering material, and the several connecting-pipes, substantially as described.
In testimony whereof I have signed my name to the foregoing specification in the presence 20 of two subscribing Witnesses.
\VILLIAM K. STEVENS.
