ALFRED STEINBART, OF CARLS'IADT, NEW JERSEY.
GENTRIFUGAL GAS-PURIFIER.
SPECIFICATION forming part of Letters Patent No. 775,462, dated November 22, 1904.
Application filed May l2, 1904. Serial No. 207,591. (No model.)
To all whom, it may concern:
Be it known that I, ALFRED STEINBART, a citizen of the United States, residing at Carlstadt, county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Gas-Purifiers, of which the following` is a specification.
The object of my invention is to provide a new and improved gas-purifier for the purpose of removing impurities from gas taken from blast-furnaces, coke-ovens, gas-generators, &c., and which is to be used for operating internal-combustion engines.
In the accompanying drawings, in which like letters of reference indicate like parts in all the figures, Figure l is a vertical transverse sectional View of my improved gas-purifier. Fig. 2 is a vertical central longitudinal sectional view of the same, parts being broken out and others shown in section. Fig. 3 is aside view of the same, parts being broken away and others shown in section, Figs. 2 and 3 being drawn on a smaller scale than Fig. l.
The purifier is constructed with a rotary fan mounted in a cylindrical casing, the axis of the fan being horizontal.
The case is formed with the two halves or sections A and B, lwhich are bolted together and are in turn supported on a suitable base. The half or section A is provided on its outer side with a central outwardly-extending enlargement C, which communicates with a tapering inlet-duct C', which, as shown in Fig. 3, is curved approximately spirally at the lower end, where it merges into the enlargement C, so as to give the entering gas a rotary movement before it enters the casing proper. A sleeve D is secured in an opening in said lateral enlargement or chamber() and projects from the inner and outer surfaces of the same, and in the outer end of said sleeve D a thrust-bearing Dl is screwed for the horizontal fan-shaft E, which is mounted at one end part in this sleeve D. A suitable oil-cup D2 is secured on the outer end part of the sleeve D for the purpose of lubricating the bearing. rlhe'other half or section, B, of the cylindrical casing for the rotary fan is also provided at its center on the outer side with the laterallyextending enlargement or chamber F, which vcommunicates with the flaring gas-outlet duct G, the lower end of which is also curved spirally where it communicates with the chamber F, so as not to check the rotary movement of the outgoing gas.
A sleeve H is secured in a central opening of the walls of the chamber or enlargement F to form a bearing for the fan-shaft E, which shaft carries a driving-belt pulley E at its outer end. A suitable lubricating-d uct H2 is secured on said sleeve H. Part of the shaft E is increased in diameter to form two shoulders E2. A hub J surrounds that part of the shaft of greater diameter, which hub has a flange J and an internal shoulder J 2, against which the left-hand shoulder E2 fits. A plate K2 rests against the right-hand shoulder E2 e and is adjacent to the inner surface of the wall of the enlargement or chamber F. Bolts K are passed through the iiange-of the hub through a metal disk K, resting against the flange J', the inner ends of which bolts are screwed into the plate K2, as shown.
A series of radial wings L are secured to the central disk K, each having its inner end beveled off, as shown at L, so as to taper from the edge of the opening forming communication between the'chamber C and fan-casing j toward the hub J, and the said plates or wings L are connected at their free edges by an annular disk M close to the side of the section `A of the fan-casing. To the opposite side of the disk K, L-shaped radial wings N are secured, the shorter inner arms N/ of which project outward into the enlargement or chamber F of the casing-section B. The outer edges of the longer arms of said wings N are connected by an annular disk O, which is close to the side wall of thev section B of the fancaSing.
Between the iianges of the sections A and B an annular water-chamber P is formed around the casing and is provided at the top with a pipe Q/ for admitting water Linder pressure. The inner wall of this chamber is formed by a rib R, projecting outward from an annular plate S, concentric with the rotary fan and a short distance from the circumference of the same and which, as shown, has slightly greater width than the fan. Within this rib a series of IOC openings or waterways T are formed which are tangential to the inner surface of the annular' plate S, and these waterways are formed at equal distances around the entire circumference of the fan. In the eXample shown there are siX; but there may bev more or less. At the bottom of the casing outlet-pipes a for the waste water and dirt are provided.
The fan-casing is provided at its circumference with a lateral enlargement W or annular chamber which is formed around the circumference of the fan-casing. As shown, this enlargement extends laterally-that is, it has greater width than the fan-casing, and where this chamber meets the outer side walls of the casing proper a knife-edged annular rib Y is formed which projects beyond the circumference of the fan proper. Between the edge and the outer side of the wall of this enlargement W an annular pocket I) is formed around the entire casing at each side, which pocket communicates with the chamber W.
The operation is as follows: The fan is rotated in the direction of the arrow fr, Fig. 2, and the gas to be purified enters in the direction of the arrow y, Figs. 2 and 3, and the purified gas is discharged in the'direhtion of the arrow e, Figs. l and 3, the speed of the entering gas is increased, and to this gas is given a rotary motion by the volute form of the inner end of the inlet-duct and enters that half of the fan between the central disk K and the lefthand casing-section A, Fig. 1, passes over the circumferential edge of the disk K, and enters that section of the fan between the disk K and the wall of the righthand casing-section B, and then passes into the volute inner end of the exit-duct, which volute conformation prevents a sudden checking of the gas. By centrifugal force the particles of solid matter and like impurities carried along with the gas are thrown outward against the inner surface of the annular plate S and are washed by the jets of water issuing from the fan-casing proper through the tangential opening Tin the direction of the movement of the fan and also of the movement of the gas carried around by the fan, and said water Hows to the side edges of the annular plate S and passes into the grooves and the enlargement W. rIhe knife-edges Y at the top of the upper half of the casing prevent the water from flowing from said grooves down the inner faces of the side walls of the casing. The water flows from these grooves into the bottom pockets WV and from the same is carried off through the bottom outlet-pipes a.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
