GEORGEV.-NORTHEY, both of the city, county;
and State of New York, have invented certain new and useful Improvements in Desulphurizing-Furn'aces, of which the following is a specification.
This invention has referencejtoan improved furnace'for desulphurizing ores in which the heavier particles of pulverized ore-are twice exposed tothe oxidizing-fire of the furnace, while the lighter particles are conducted off and passed through settling-chambers, where they are deposited by the action of sprays of water in the collecting-pans of the settling-chambers.
The invention consists in the combination and arrangement of parts, as hereinafter described and claimed.
The accompanying drawing represents a vertical longitudinal section of our improved furnace for desulphurizing ores.
A represents the vertical shaft of our improved furnace, at the bottom B of which is arranged a hopper-shaped car on rails, which car fills up the entire pit of the furnace.
At one side of the furnace, and immediately above the pit, is arranged an ore-injector, O, which is worked by compressed air or steam, and which receives the pulverized ore from a suitable feed mechanism, so as to take it up and conduct it, thoroughly mingled with air or steam, in upward direction through the furnace shaft.
On'or somewhat above the level of the oreinjector 'O is arranged a hydrocarbon-injector, D, which receives its supplyof hydrocarbonfrom a tank, D, at asuitable height above the injector, and its steam-supply from the steamboiler. The steam-supply pipe D of the hydrocarbon injector, as well as the pipe 0, which conducts the steam or compressed air to the ore-injector C, is'preferably conducted through the wall of the shaft A to the interior of the same, and exposed in the form of a coil, or otherwise, to the high temperature within the shaft, whereby the steam is superheated before it passes into the hydrocarbon-injector 1D, and also the air or steam heated up to-a high temperature before it passes into the oreinjec'tor G. The hydrocarbon injector D is arranged in acasing set into an opening of the wall of the shaft. The lllOlltltOf the opening has a slight upward curve, as shown clearlyin the drawi'ng, ,so that the flame from the hydrocarbon-injector is deflected in upward direction and thrown against the ascending column of ore particles. The particles of ore are consequently carried along by the draft of the flame and the sulphur oxidized by the oxygen which is supplied by the air,imp'el'- ling the ore particles'in upward direction, whereby the sulphur contained even in the smallest particles is oxidized. The decomposition of the steam used by the hydrocarbon injector increases the heat in the shaft, the
presence of the hydrogen gas exerting a special beneficial influence upon the ores treated. The light oxidized particles of ore are then carried through a cast-metal conducting-pipe, E, from the top of the shaft in downward direction into the first settling-chamber, F. Theheavier particles, which are not carried over by the draft of the flame, are dropped by the force of gravity, and are thereby compelled to pass a second time through the flame against the direction of the same, so that the sulphur contained therein is fully oxidized. The heavy particles of ore are then collected in the hopper-shaped car in the pit of the shaft. From the first settling-chambers, F, the lighter ore particles are conducted successively through a series of settling-chambers, F F F F-*, which are connected with each other by means of openings arranged alternately at the top and bottom of the partition-walls of the chambers. At the bottomof the settling-chambers are placed water-pans, in which the light particles of ore are deposited. chambers, F" and F, are connected by a conducting-pipe, G, of inverted U shape, which pipe is provided at its upper bent portion with spray-nozzles that are supplied with water by a pump, said nozzles being opened or closed by suitable mechanism, as shown in the drawing. The'sp'ray of water acts upon the column of light ore particles in the ascending and descending part of the pipe G, so as to cause the gradual settling of the same in the water-pans of the settling-chambers F F". If desired,--a second connectingrpipe, G, with water-spray arrangement, may be arranged in connection with the next adjoining settling-chambers.
The second and third set-tling- AVAILA 313 my;
From the last settling-cliambcr the gases of combustionand such particles of ore as are still carried along by the same are conducted by means of a cast-metal pipe, H, having an exhauster, H, and a water-spray, H into a settling-tank, I, which is filled with water, and
from which the remaining gases escape to the atmosphere. Alongside of outside of the settling-chambers is arranged a water-box, with which theoverflowpipes of the settlingpans communicate. The ore particles deposited in the settling-pans are removed from time to time'by means of doors at one side of the set fling-chambers.
In this desulphurizing-fur11ace,wl1ere the ore and flame injectors with upwardly-directed discharges are arranged opposite each other near the bottom of the shaft, the heavier particles of ore are exposed twice to the oxidizing action of the same flame within the shaft and allowed to settle at the bottom thereof, while the lighter particles are drawn off at once after passing through the flame. The desired result is obtained under this arrangement with greater economy of fuel. than in furnaces where all the ore particles are made to circulate repeatediy within the shaft, or in furnaces where the heavier particles are passed successively through separate chambers where scparate' hers for the finer ores, a pipe connecting the top of the shaft with said settling-chambers, and an exhausting device, substantially as descrilced.
In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
