APPARATUS FOR SEPARATlNt-FANDCOLLECTING IMPURI TIES'FROM METALLURGICAL-FURNACE GASES.

SPECIFICATION forming part of Letters Patent No. 725,352, dated April 14, 1903.

Application filed November 3, 1902. Serial No. 129,900. (No model.)

To all whom it may concern:

Be it known thatI, EDWARD J. MCALEER,

a citizen of the United States, residingat.

bad therein to the accompanying drawings.-

The object of my invention is to provide new and improved apparatus for removing and collecting dust, impurities, &c., carried in the gases or fumes given err frommetallurgical furnaces, and particularly blast-furnaces.

In the accompanying drawings,whichillus1- trate an applicationof my invention, Figure 1 is a part-elevational view and a part-s'ectional view of an apparatus constructed in accordance with my invention. Fig.2 is a broken part-elevational and part-sectional' view of the separating-chamber. Fig. 3 is an enlarged detail sectional view of collectingtank, and Fig. 4 a'similar view taken at right angles to view of Fig. 3.

Referring to the drawings, the separatingchamber 1 is supported by columns 2 and is preferably of the constructionillustrated.

Gases from affurnace or a set of furnaces are. introduced into the separating-chamber at its top through-an inlet-pi'pe3 and pass downwardly and upwardly through passages 4: and

5, formed in the chamber 1 by the sides there of and a dividing-wall'6. The gases, after their travel through the chamber, pass into a flue or passage 7, from whencethey are conveyed to hot-blast stoves, boilers, &c. as may be desired. Conveniently placed within the separating-chamber is a slotted or apertured pipe 8, through which a fluid is discharged into the path of travel of the'gases, thereby causing said gases topass through the stream from said pipe. The bottom of the separating-chamber is preferablyprovided with inclined walls 9, which'communicate with a discharge-nozzle 10. Discharge-nozzle 10 extends down into a receiving or collecting tank 11, into which the particles freed from the moving gases are precipitated. In practice tank 11 is kept supplied with a sufficient quantity of water, so that the lower end of the discharge-nozzle willextend under the surface of the water a sufficient distance to overcome the gas-pressure. Theremoval of the dust, &c., which settles at the bottom of the tank is effected through discharge-pipe 12, which, as illustrated by Fig. 1, extends into a T- coupling- 13. From the coupling the dust is conveyed through pipe 14 to any convenient point. It may sometimes be necessary in order to prevent clogging of the T and pipe 14 to employ a water-pressure. If

so,water may be obtained from pipe 15. The

discharge from the tank is controlled by a valve 16, the stem 17 of which is connected with a hand operating-lever 18. u 19 is an overflow-pipe convenientlylocated within the tank.

For the purpose of maintaining a sufficient .quantity of water in the tank 11, and particularly at the time when the dust is being removed from said tank,I introduce water thereto through a pipe 20, located directly over the top of said tank.

What I claim is 1. An apparatus for removing impurities from blast-furnace gases and collecting the impurities, comprising, in combination with a separating-chamber having inlet andoutlet openings, an open passage for the blast-furnace gases through the chamber formed by the walls of the separating-chamber and a centrally-disposed dividing-wall, a fluid-supply located in the separating-chamber through which the gases pass, a tank below the separating-chamber into which the fluid and impurities fromthe gases fall, anda valve for controlling the discharge from said tank, substantially as set forth.

2. An apparatus for removing impurities from blast-furnace gases and collecting the impurities, comprising, in combination with a separating-chamber having inlet and outlet openings, an open passage for the blast-furnace gases through the chamber formed by the walls of the separating-chamber and a centrally-disposed dividing-wall, a'fluid-supply located in the separating-chamber through which the gases pass, a tank below the separating-chamber, a discharge-nozzle leading from the separating-chamber into the tank, and a valve for controlling the discharge from the tank, substantially as set forth.

3. An apparatus for removing impurities of thefluid in the tank, a discharge-pipe from blast-furnace gases and collecting theimleading from the tank, a valve forcontrolling purities, comprising, in combination with a the discharge from the tank, and means for separating-chamber having a. fluid-supply 10- operating the valve,substantially as set forth.
