` SPECIFICATION forming part of Letters Patent. No. 419,530, dated January 14, 1890.
Application fled April 4, 1889. Serial No. 305,917.' (No model.)
Be it known that '.I, GEORGE F. KNOX, of San Antonio, in the county of Bexar and State of Texas, ha've invented@ certain new and user ful Improvement in Combined Feed-Vater Heaters, Filters, and Lime Extractors, of which the following is a full, clear, and enact description, reference being had tothe accompanyin g drawings, forming part of this speciication.
This invention relates to devices for the combined simultaneous heating and purifying of feed-water for engines, duc.; and the invention consists in features of novelty, hereinafter fully described, and pointed out in the claims. l
Figure I is an elevation of the apparatus, in which the feed-water is heated and purified at the same time, with part Abroken away to show the interior of the apparatus. Fig. II is a vertical sectionof the same, and shows thesupply-pipe which discharges water into the surmounting tank, the means for discharge of said Water from said tank onto the alternating scatterplates from which the spray descends to the hotv well, the inlet-pipe for the product. of the steam-exhaust from the engine to heat the spray, the hot Well', and the filter that purifies the feed-water, &c. Fig. III
is a top view of the apparatus, andshows the positions of the supply-pipe, the dischargepipe that delivers theheated and purified feed-water to the'boilerfor other destination, as the case may be, and the exhaust-pipes through which escapes the exhaust-steam from the apparatus. Fig. IV is a horizontal section taken on line IV IV, Fig. Il, 'and shows the top plate of the filter, through perforations in which the heated purified water l .are tightly clamped together and held by is discharged into the sui-mounting dome preparatory to its entrance into the dischargepipe that carries it to its destination. Fig. V is a horizontal section taken on line V V, Fig. II, and shows the circular plate that forms the bot-tom of the supply-tank, which plate also forms the top of the annular heatingchamber. Fig. VI is a horizontal section taken on line VI VI, Fig.` I, and eshows the hinged coupling of the vertical flanges of the sections at one side of the sectional cylinder and supply-water tank,which hinges, after the clamping-boltsarereinoved,providethemeans for unfolding the sections of said cylinder and of the supply-water tank and the consequent Opening up of the apparatus for cleaning the same.
Referring to the drawings, l represents the hot-well tank or basin, which is preferably of cast-iron cast in one piece, and is Vsurniounted by a peripheral flange 2 at top, and rests Onsupporting-
legs 3, that are secured to it by screw-bolts 4i or by any other suitable means. Y
5 5 represent the sections of the cylinder or outer shell 5fL of the annular heating-chamber 6. These two sections of the cylinder 5 (which are preferably of sheet metal, but may be of cast metal) surmount and rest on the upper edge or brim of the hot well, tank, or basin l, to which they are secured by sec- ,tional circle angle-irons 7, that are seated around the base of the
cylinder 5a, to which they are fastened by rivets 8, that pass through perforations 9 in said angle-irons and through the shell of the cylinder, and are riveted thereto; and screw-bolts 10 are seated in and pass through perforationsll in the peripheral flange 2 of the hot-well basin, and through the lower flange of the circle angle-iron 7, and thus the sections of the cylinder 5 are secured to said angle-iron and by it to the hot-well basin. the cylinder are also provided with vertical union flanges 12, which arecoupled together at one side of the column 'by hinges 13, the sections of which hinges are themselves coupled by the drop-pins 14. The inner flanges l2, both on the side of the cylinder that is hinged and on the reverse side also,
the screw-bolts 1 5, which at certain intervals pass through the perforations 1G in said union flanges, and where t-he hinges supervene similar screw-bolts, sufficiently elongated, pass through registering perforations in said hinges, as also through those in the union flanges, SO as all along t-he junctionline to effect water and steam tight joints.
17 represents a central cylindrical shell, that rises vertically from the center of the The two sections ofv IOO bottom of the hot-Well basin upward within the
cylinder 5, and which central shell is filled with charcoal 18 or other filtrant. A circle angle-iron 19 embraces the base of said central shell, to which it is secured by rivets 20.
21 represents a semi-globular Water tank or basin, which is secured to the bottom of the hot-well basin, from which it hangs pendent, and to the lower flange of the angle-iron 19 by screw-bolts 22, that pass through perforations 23 in the
peripheral flanges 24 of the basin 21 and through the said bottom of the hot-Well basin and said angle-iron.
25 represents a circular perforated plate, which forms a cover for the basin 21, and intervenes between the same and the filtrant in the filter-chamber above it.
26 represents a perforated plate that surmountsthe central shell, which incloses the filter-chamber, and which itself is sui-mounted by a semi-globular dome 27, which receives the hot purified feed-water from the filter and delivers it to the discharge-
pipe 28, which carries it to the boiler or other destination.
The threaded end of said discharge-pipe is` surmounts the cylinder 5l and surrounds the shell ofthe filtering-chamber. The said plate sits on and projects peripherally from the top of the said
cylinder 5, and is itself surmounted by the vertical sections 36 36 of the cylindrical water-supply tank or basin 56, to which the ring- plate 35 forms the bottom, and which bottom is provided with pertorations 37, through which the feed-water gradually percolates into the annular heating-chamber to be operated on. The sections 36 36 of the cylindrc water-suppl y tank areprovided with vertical union flanges 38 at their junctionline,which are on line with the similar union flanges of the sections 5 5 of the cylinder 5, that surrounds the annular heating-chamber, and on one side the flanges are coupled together by a hinge vertically directly over the hinges already described, that couple said sections 5 5. sections of the cylindric water-tank is a counterpart of those that connect the cylindric sections 5 5 beneath, as shown in Fig. VI, and is alike numbered and so need not be again here described.
Screw-bolts 39 engage in perforations`40in the union flange 38 of the water-tank and tightly enforce the connection to produce water-tight joints on cach side of the tank, and a similar screw-bolt, but suil'iciently that embrace the top of the
sections 5 of the cylinder 5, as also duplicates thereof, both the base and top of the sections 36 of the cylindrical Water-tank. These angle-iron sections, as do those at the base of the sections 5, are so placed that their junction ends register wit-l1 the junction edges of the semicylinders that they embrace. The circle angle- irons 41 are secured to the cylindrical sections they embrace by rivets 42, which pass through perforations 43 in the vertical flanges of the angle-irons and the sectional cylinders.
44 represents the circular top -pl'ate that covers the supply-water tank and surmounts the
whole cylinder 5.
Thehorizontal flanges of the sectional circle angle-
irons 41, that embrace and are riveted, as stated, to the top of the sections 36 of the water-tank, are secured to the said top plate by screw- bolts 45, which pass through perforations 46 in said angle-irons and said top plate and are screwed down, so as to secure a tight joint.
Similar screw-bolts 47 pass, respectively, through perforations 48 in the horizontal flanges of the union angle-
irons 41, that embrace and are riveted to the top of the cylinder 5, and through those sections that are riveted to the base of the sections 36 l of the cylindrical tank, and also through the intervening ring- plate 35, that separates the annular' heating-chamber from the watertank, and the screw-nuts of said bolts being f screwed down tight a water and steam tight joint is effected thereby.
pipe 28, that rises from the apex of the semi-globl ular dome 27, passes through a hole 49 in the 4;center of the top plate 44 and through the angle-flange collar 50, which is secured to said top plate by rivets 82. Three exhauststeam pipes 51, whose threaded lower ends have a steam-tight engagement in the screwthreaded perforations 52 in the ring- plate 35,
`ascend through perforations 53 in the
top plate 44 and through the angle-flange collars 54. These pipes carry off the exhaust-steam i after it has been fully utilized, and act also as lbloW-off pipes to facilitate the ascent ofthe steam through the annularheating-chamber. The hinge that connects the 55 represents the supply-pipe, which receives the feed-water from the hydrant `or any other convenient and suitable supply,
" and delivers it into the cylindrical watersupply tank 56. The said supply-pipe enters the said tank through the angle-flange collar 57 and the perforation 58 in the top plate of the tank, and union elbow-joint pipes 59 connect the sections 55 of the water-supply pipe.
60 represents scatter-plates, that are secured by rivets to
brackets 61, which by the same IOO IIO
419,53o f s means are secured in alternate succession to the central
cylindrical shell 17 and to the sectional cylinder 5n in the annular' heatingchamber 6.
62 represents the exhaust-steam pipe from an engine or other device using steam, the Iianged collar 63 on the front end of which pipe is secured to the projecting boss-
collar 64, that surrounds the open port 65, that passes through one of the sections 5 near its base, and is secured to said cylinder by the screw bolts 66, which pass through said anged collar, through the packing-ring 67, of rubber or other suitable material, that intervenes between the flange-collar and bosscollar, so that when said bolts are 'screwed home a steam-tight joint is'effected.
68 representsthe suction-pipe to the boilerfeed pump, thescrew-threaded end Vof which pipe is ti ghtseated within the screw-threaded collar-flanged opening 69, that enters the hot Well near its base, and 70 is the return forcepipe from the boiler-feed pump, the screwthreaded end of which has Aa steam-tight screw-seat within the collar-hanged opening 7l into the semi-globular tank 2l, beneath the central filter-chamber.
7 2 represents the blow-oit pipe, whose screwthreaded upper end is steam-tight, seated within the screw-fianged collar 73 at the bottoln of the semi-globnlar tank or basin 2l,
and 74 is a globe-cock which is adjustable" Within said pipe to provide, respectively, an open or closed port, as is differentially re'- quired when blowing oft', iiushinggror otherwise. This blow-off pipe, which is used when cleansing the heater, discharges into the sewer or any other suitable drainage.
I will now describe the automatic device by which the supply of feed-water is made self-adjusting and dependenton the exhaustV of the water in the hot Well. 75 represents a cut-od valve of usual construction that works within the valve joint-pipe 8l, which j oint-pipe connects two sections of the watersupply pipe 55. The operating-rod 7 6, that carries and actuates said valve, passes horizontally through the steamt'ight packing-box 77 and is rigidly attached'to' the crank-arm 7 S, from which hangs pivoted the pendent rod 79, to which is attached the buoyant ball 80, that floats on the surface of the water in the hot-Well basin. As the Water subsides in said hot well, the lowering of its surface carries with it the buoyant ball 80,'that floats thereon, which, by its pendent connecting? rod 7 9,turns the crank-arin7 S, the operatingrod 77, and the cut-off valve 75, by which the port in said valve is brough-t nearer into coincidence vwith the tube-opening` of the supply-pipe, so as to increase the supply of feedwater. It will thus be seen that the lower the surface of the water falls in the hot well the nearer will the open ports of said valve be brought to register Wit-h the tube-open in gs' of the supply-pipe, and also, Vvice vversa,whe n the supply exceeds the demand and the water in the hot well in consequence'rises the valveports are thereby turned in 'the reverse direction to any degree required, even', if need be, before the Water rises sufficiently to flood the steam-port 65 to constitute the valve a complete cut-off until the subsidence of the water in the hot Well. lVhile I prefer to use said ball-and-valve device to automatically regulate the supply of feed-water to the apparatus, yet when desired a common globe-V valve similar to the one shown and described in the blow-off pipe, and which is then actuated by the vhand of the operator, may be substituted in the place of said automatic 3 device. S3 represents the glass water-gage that indicates the height of the Water in the hot Well, so that the operator may observe if the necessary supply of feed-Water is cutshort from any cause. 84 represents the hand-hole in the side of the hot-Well basin, to give access tothe same for cleansing it of scale and deposits of mud, lime, duc. j The shutter-plate 84, that (when the apparatus is in operation) closes the hand-port, is retained to its seat, so as to preserve a water-tight joint, by the screw-bolt 86, which passes through the concavo-conveX plate 87, and Whose screw threaded end engages in said shutter-plate and brings it tightly home toits seat.- 88 represents a globe valve or cock in the Watersupply pipe 55,which vis used as a cut-od when itis desired'to shut down the operation of the apparatus, and it may'also be used'to regulate the supply of feed-water when it is not desired to use the floating ball-valve. 'The supply-pipe may either take thewater direct from the hydrant or any other Water-supply that has sufficient head to deliver into the IOO supply-tank 56 at the summit of the appa-l ratus, or the water may, when circumstances make i-t desirable, be transferred from a prefI paratory feed-water heater, for `the invention is applicable in either case. i
The operation of the apparatus is as fol-v lows: The feed-water enters through the supply-pipe 55 into the supply-tank I56, from which it percolates at the speed required, as indicated by the straight arrows, through the perforations 37 in the circular ring-
plate 35,Y which forms the bottom of the supply-tank and the top of the annular heating-chamber. The "water as it thus. percolates into said heating-chamber drips onto the succession of scatter- plates 60, that are, as shown in Figs.l I and II, respectively, alternately projected outwardly from the central cylindrical shell 17, that incloses the filter, and inwardly from the sections 5 5 of the cylinder 5, forming the outerwall of the annular heating-chamber 7. The Water drops and splashes from one scatter-plate to another in its descent from the supply-Water tank at the summit of the apparatus to the hot well at its base, dashing alternately outward'and inward in a fine spray from scatter-plate to scatter-plate A At the same time the hot steam, provided by an engine exhaust-steam-pipe 62, enters through the open port G5, near the base of the cylinder 5, and as it ascends, as indicated by curved arrows within said' heating-chamber, it comes in contact with the descending feedwater,which, being separated into a fine spray as it dashes from plate to plate, is quickly heated by the ascending steam. During the utilization interchange of temperature between the ascending steam and descending spray, a large portion of the lime, sulphur, dirt, and other impurities that are contaminating the feed-water is deposited on the scatter-plates. By the time the water has reached near the base of the heating-chamber it has come to be in a highly-heated condition. Vhen on a line with the open steamport it encounters the superheated steam on its first entrance within the chamber, and while experiencing the still further sudden increase in temperature thereby engendered, the remainder of the lime, sulphur, and other impurities still left in the water is precipitated to the bottom of the hot well. The water is drawn from the hot well by any suitable engine-pump that is not subservient to the adverse movement of the steam that evaporates from the water, and said water, passing through the suction-pipe G8, is forced, iria the return-pipe 70, into the semi-globular tank or basin 25, and through the filtrant within the central shell, from which the pressure discharges it through the perforated plate 26 into the semi-globular dome 27, and finally through the discharge- pipe 28 to the boiler, when used for feed-water, or when the apparatus is used for purifying purposes, as in breweries, bakeries, hotels, the., to their clearwater tank or reservoir. There is an especial advantage in the water increasing in temperature as it passes downward, the steam at the same time rising upward and at the waters highest temperature meeting the steam when hottest, thereby causing the remnants of lime, sulphur, or any other impurities therein to be precipitated or extracted, or should there in some cases be a very small amount of said impurities left, the filter is abundantly able to cleanse out the last vestige thereof and furnish to the boiler or reservoir, as the case may be, perfectly-pure feedwater. When it is desired to blow 01T or fiush the apparatus to cleanse it, when the globe valve or cock in the blow-off pipe is turned to register its open port in line with the tubeopening of the pipe the cleansing is usually easily effected, the supply-water being turned on and the pump being operated at the same time. Vhen, however, the scale and deposit in the hot well are so extensive that it is desired otherwise, to remove them, the hand-hole plate is removed, as stated, and easy access is thus had thereto. lVhen it is desired to open up thc cylinder 5, or the cylindric water-tank, the clamping and connecting screw-bolts are removed from the flanged edges of their section -plates and from the angle-irons and hinges, when the sections can be easily opened out on their hinges, so as to remove thc scale from the scatter-plates, 8vo., and to clean up the heater and tank, also, when required. It is very seldom required, however, to open up the water-supply tank 5G, and it will be seen that when half of the bolts that connect the said tank with the cylinder 5n are removed, the latter isfreeto be opened out on its hingeswithout disturbing or opening the tank. Should it be desired to take the sections of the cylinders completely apart, the drop-pins 14 can bc drawn out of the hinges 1 3, and thus the hinges and the sections they carry are uncoupled.
Some of the advantages of this feed-water heater and purifier are: It obviates the necessity of putt-ing any back-pressure on the engine; heats the water by actual test to 210o and 212 Fahrenheit; extracts all lime, sulphur, mud, and other impurities from the water, and keeps the boilers free from scale or deposit; also, the simple construction of the heater and the facility of removal of the scale and deposit afforded by the sectional construction of the outer shell of the apparatus provide the means for opening up the same when cleaning.
I have shown and described a sufficient number of clamping-bolts along thc vertical` lianged edges 12 of the
sections 5 to enforce a tight joint along the flanges; but, if desired, a large proportion of said bolt-s may be dispensed with by providing vertical re-enforce clamping iron bars on each side of the flanges, through perforations in which bars, registering with others in the flanges, screw-bolts are secured. It is evident that when the nuts on said bolts are screwed home tight the stiffness of the clamping-bars pressing against the fianges will preclude the necessity of using as many bolts.
It will be seen that as no part of the apparatus is subjected to dry heat, the scale and deposit are generally sufficiently soft and free, when the valve in the blow-olf pipe is opened, for the steam in blowing off or the water in flushing to thoroughly cleanse the apparatus.` Then steamy when blowing off may be furnished by the engine that provides steam to the exhaust-steam pipe 12 by connecting, if desired, with the pipes 2S and 51 at the top of the apparatus, when it is desired that the blow-off shall be direct from top to bottom.
In conclusion, I call attention to the fact that there are no coils or other secretive parts in the apparatus, but when opened up for cleaning all parts are readily accessible to both the eye and the hand.
