GAS-CLEANING- MPARATUS.

Application filed September 8, 1920. Serial No. 408513.

To all whom it may concern: 4

Be it known that I, GEORGE P. Pmnme, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in a Gas-Cleaning Apparatus, of which the following is a specification,

My invention 1s for a gas cleanlng apparatus and has for its particular ob]ect the;

provision of means for cleaning blast furnace gas as it comes from the blast furnace, by washing the gas so as to remove the particles of dust and dirt therefrom, at the same time to cause the gas to pass through a pair of rotors or beaters having fiat blades and which will thoroughly remove all particles of dirt and dust from the gas.

Another object of m invention is the provision of means whic are simple and ellicient in operation and which can be easily cleaned, and at the same time thoroughly washing and cleaningthe gas so that all articles of dust and dirt are removed thererom. Y

These and other objects of my invention 'will be more fully and better understood by re er to like parts throughout, a rectangular shaped receptacle 10 is shown having a gas inlet pipe 11 at one of the upper corners and a gas outlet pipe 12 centrally locatedof said casing and on the opposite side from the inlet pipe. Mounted in said receptacle 10 in suitable bearings and extending longitudinally thereof, is a shaft 13 at the outer end of which a gear wheel 14 is secured. Secured to the said shaft 13 is a rotor 15 comprising a plurality of blades or paddles 16, the said blades being four in number, and extending outward from the shaft 13 at right angles to each other. Mounted below the said shaft 13 and parallel therewith is a second shaft 17 mounted in said receptacle in the same manner asthe shaft 13 having a ear. wheel 18 on the outer end thereof.

ounted upon the said shaft 17 is a rotor 19 comprising a pluralit of blades or paddles 20 extending outwar from said shaft and at right angles to each other in the same manner as the rotor described above. The rotors 15 and 19 are mounted in such manner that the blades of one rotor are onequarter of a turn ahead of the blades of the other rotor, so that the blades 16 and 20 of the rotors respectively will pass between each other as. they are rotated, very much on the principle of an old fashioned egg beater. A motor 21, to which is secured a gear wheel 22 in mesh with the gear wheels 14 and 18 respectively, upon the shafts 15 and 17, provides means for turning the rotors 15 and 19. Mounted above the-casing 10 and leading to a suitable source of water supply is a pipe 23 having a series of connecting pipes 24 leading from said pipe 23 into and through the casing of the receptacle 10, so that a supply of water is directed down upon the gas passing through the casing 10 and upon the rotors 15 and 19. Pins 25 are provided which are inserted into the casing of the receptacle 10 and crossed over each other over the pipes 24 so that the streams of water passmg into the casing from the pipes 24 will be broken up. In practice spray nozzles may be secured to the ends of the pipes 24 so that a spray of water is directed upon the rotors 15 and 19 if desired. A siphon outlet pipe 26 is rovided which is secured to the casing of t e receptacle 10 at one of the lower corners thereof, so that the supply of water in the receptacle 10 is maintained at a uniform height at all times as long as water is supplied to the washer through the spray nozzles. A plug 27 is also provided in the lower part of the gas washer to provide means for cleaning the dust and dirt out of the receptacle 10 which is likely to collect in the bottom of the casing 10 and which will not be carried out through the pipe 26.

The operation" of the device, as will be readily understood, is comparatively simple, the gas entering through the pipe 11 is impinged against the upper rotor 15 upon which the streams of water from the pipes 24 are being directed. The rotor 15 in combination with the rotor-19 revolving rapidly break up the currents of gas and subject the gas to a beating operation so that particles of dust and dirt are impinged against the blades of the rotors and arewashed down into the bottom of the receptacle by the streams of water passing down over the rotors. The water rises to a height as indicated at 28, so that the blades of the rotor 19 pass downward into the water and are efiectively washed at each rotation of the rotor. The gas assing into the rotor is thus thoroughl beaten and asses. downward against t e rotor 15 an on down to a point between the rotors 1.).and 19 and thence out-ward through the outlet pipe 12 so that it is impossible for the gas to pass through the rotor without coming in contact with the blades of the rotor so thatthe particles of dust anddirt are removed from the as. v

ile I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departin from the spirit or scope of my invention.

claim: L 1 a 1. A washer for blast furnace gas, comprising a chamber, a pair of horizontaland super osed rotary gas beaters mounted in the e amber, means above the-heaters for spraying water downwardly thereon, a gas aeeaore zontal and superposed rotary gas heaters .mounted in the chamber, each gas beater having a plurality of radial blades extending longitudinally-of the beater, the heaters being disposed so that the bladesv of each beater .pass between the blades of the other beater during rotation of the heaters, a gas inlet conduit leading into the chamber above the heaters and near one end of the upper beater, a gas outlet leading from the chamber. opposite the gas inlet and at a level between the axes of the beaters, means above the beaters for spraying Water downwardly thereon, and an overflow device for maintaining a water level below the as outlet and above the bottom of the lower ater.
