APPARATUS FOR PuRii-'YING WATER FOR BoiLERs.
SPECIFICATION forming part of Letters Patent No. 2"l'1,8%1,7datedA February 6,. 1883.
I i Application filed December 6,1882. (No model.)
Apparatus for Purifying Tater for Boilers, off `which the following is a specification.
Myinvention relates to an appara-tusadapt-4 ed to be placed'in the interior of a boiler for thepurpose of-puritying the water previous to its use in the boiler.
1 flaring drip-funnel into the settler.
It consists of a closed cylindrical settler having a dri p-i'unnel opening into the settler to receive the inijowing water, and an overow through which the puiiied water escapes into the boiler. The settler has legs, which rest upon the tubes of the boiler, and the whole apparatus is placed above the Waterlevelin the boiler. i
The body of the settler maybe made square as Well as cylindrical.
The water is introduced into the apparatus through a perforated spiral pipe at or near the top ofthe boiler, abovethe water-line, and falls in'a fine spray` through the mouth of the It there deposits its impurities. Such as are sufficiently heavy sink to the bottom. while the lighter impurities float onV the surface above the level of the interior opening o`f the overflow, which extends for'some distance into the settler ior this purpose. The purified water then escapes by the exterior mouthot'the overflow, which' is on a lo'wer level than the mouth of the drip-funnel. The sediment is removed by means of a blow-off adapted to the settler. A check-valve in the overflow closes thatopening when the blow-olf is opened, so that the steam is caused to enter at the drip-funnel and effect a thorough cleansing ofthe settler by traversing it from -end to end. i
Itis necessary that the drip-funnel should extend some little distance into the settler, in
order to secure the air-space inside the settler into which the impurities mayrise. lt should not, however, extend as far in'to the settler as the overflow. By spraying the water previous to itsintroduction into the settler it is exposedwto the high heat of the boiler, and the depositing of its sediment greatly assisted.
In order to supply chemicals to the water in the settler, I attach a brauch pipe to the feed-pipe, through which the chemicals are forced by a force-pump or other suitable means into the feed-pipe, 4and thence carried to the settler.
`1n the accompanying drawing, which represents my invention, A is the boiler. B is the perforated spiral feed-pipe. C is the dripfunnel. D is the settler. F is the overow extending below the level of the Water iu the settler. VG is the checkvalve. H H are the legs of the settler, resting on the tubes l I of the boiler. K is the level of the water in the boiler. L is the level of the-water in the settler, and M that of the sediment deposit.
Iain aware 4that a branch pipe has been connected with the feed-pipe of a boiler for the purpose of supplying matter to the water within the boiler to prevent the formation of crusts in theinterior of the boiler. Such feed and branch pipes are. shown intPatent No. 22.249, granted J. H. Harnett,'Deceinber 7, 1858; but I am not aware that any such feed system for chemicals has been used in combination With'a settler within the boiler, Where- 'in the chemical .action to purify the water takes place within the boiler, and thus securesclaim as new, and desire to secure by Letters Patent, is-
1. The combination, with a closed settler within the boiler, of a. feed-pipe, a branch pipe attached to the feed-pipe, and means for forcing chemicals through the branch pipeV into the settler, substantially as hereinbefore set forth.
2. As a new article of manufacture, the apparatus for purifying water within a boiler,
consisting in the combination of the drip-fune` nel, the closed settler, the check-valve, the overflow extending into the settler, and thev blow-oft', substantially as`hereinloefore set forth.
