Specification of Letters Patent.
Patented Feb. 1, 1910..
Application filed August 17, i907. Serial No. 388,959.
vented certain new and useful Improvements in Gas-Cleaning Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and" use the Samt-'2.
My invention relates to gas cleaning apparatus and more particularly to apparatus for cleaning th'e gas issuing from blast furnaces.
The object of my invention is toprovide means for separating the heavier and finer particles of solid material from the gas by gravity and centrifugal action, means for reheating the gas before using, and also means for washing the gas in such cases where that course is desirable, and the invention consists in the novel construction hereinafter described and claimed.- My cleaning apparatus can also be used in connection with metallurgical processes for the 4,extraction of valuable particles from the gases or from' the dust and for various similar purposes in the different arts.
In the accompanying drawings forming art of this speclcation and in which simi i ar characters refer to corresponding parts,
modification, and Fig. 6 is a vertical trans-4 verse sectionof a modified form showing parts in side elevation.
Referring to the drawings by number, 1 represents the tunnel-head of a furnace having the risers 2 which are preferably in pairs, each pair being connected 'with ay down-comer 3 which is brought to a level suitable for the location of the cleaning apparatus. the furnace and the main section of the cleaning apparatus has an opening in the A-dust-catcher d located between side thereof to which the down-comer is connected. rlhis dust-catcher consists of a central, cylindrical portion 5 with conical upper and lower sections 6 and 7, and the downcomer is connected with the cylindrical portion at a point near the top thereof.
'At the apex of the cone forming the upper section, a pipe Sis connected, which leads to the se arator and cleaner 9, and the lower conica section is provided with an opening, normally closed by a dust-valve 10, of the ordinary construction.
The cleaning apparatus 9 consists of a horizontal cylindrical casing 11 with a assageway or gas return pipe 12 extent ing through the central portion thereof, and an internal helical partition 13 located between the outer casing and the central return pipe or conductor just referred to. An outlet 14, through which the gas passes as it leaves the apparatus, is located at the end of the casing. Connected to the lower side of the casing 11 and located between each of the flanges of the helical partition is a trap 15 into which the dust falls through the opening 16, between the circumferential portion 23 of the casing 11, and the approximately tangential portlon 17 which latter is turned downward as shown, this arrangement serving to catch and retain the dust particles in the trap 15, as they are projected therein by the combined action of centrifugal force and gravity. The traps are normally closed by dust-valves 18 of the ordinary construction. The traps are substantially frustum-shaped in cross section and the upper portion of the side walls coincides with the flanges of the helical partition, thereby formino' a continuous chamber for the passage of5 the dust particles. ln the drawings l have shown these traps as located on the lower side of a horizontal casing, but it is not essential that this particular form ofconstruction should be adhered to, inasmuch as the lforce of the current ofgas is sufficientto carry the dust into the tra s if the latter are connected to the sides o a casinp arranged vertically. 0n the other hand,li the separatinor apparatus is arranged horizontally the faorce of gravity may be depended upon to aid in carrying the heavier particles to the bottom. Cleaning holes 19 and 20 in the casing and danges are closed by ordinary covers.
- not make its exit from the casing until it is then drawn ol' through the pipe 8, and is has passed through said return. In this modification I have also shown a water pipe 22 located near the inner surface of the casing, in this instance on the upper side thereof, and passing through the flanges of the helical partition.
The operation of the apparatus is as follows :-'l`he gas passing from the furnace envters the dust-catcher 4 through the connecting pipe 3 and byreason of the decreased ve- Alocity of the gases in said dustcatcher due to its large size as compared with its cong .necting pipes, the. heavier particles carried by the gas gradually fall by gravity to the i lower conical section 7, where the force of current is diminished, the dust descending to the lowest point, where it can be readily removed by the operation of the valve 10. The gas freed from these heavier particles carried to my separating apparatus 9, where it is conducted throu h the space between the flanges of the helical partition and escapes through the outlet 14. During the passage of the gas through the spaces formed by the flanges of the he ical partition, the parl ticles of dust will fall into the traps and will be held there until removed by the operation of the valves 18. The plates 17, partially covering the entrance to the traps, prevent the current of gas from stirring up i the dust after it has passed from the cleaner proper, and owing to the fact that the side walls of the traps coincide with the walls of i the helical partition, there is as little obstruction as possible in the path of the dust particles. It will thus be seen that both centrifugal force and the force of gravity are l made use 'of in the process of separation. In reheating the gas before using it, in order that the temperature of combustion may be higher, it is passed through the central rei turn pipe 12, where it will take up a portion of the heat given off by the gas passing around the return pipe. In using the modification shown in Figs.` 5 and 6 the gas is sprayed with water as it passes through the space between the fianges of the helical partition, and then immediately enters the central return pipe withi out passing from the casing. During the passage through the return pipe the gas is reheated and as a portion of the heat is thus extracted from the gas tiowing around the return pipe, less water is required for the washing operation. The Water sprayed into the apparatus renders the dust particles bottom and into the traps more rapidly, and
the pools of water formed in the traps will still further aid in the operation of separating the foreign material rfrom the gas.
