WILLIAM H. ROBERTSON, OF BROOKLYN, YORK.
DUST-COLLECTOR.
Specification of Letters Patent.
Patented J an. 2, 1917.
- Application filed June 1916. Serial No. 108,706.
To all whom it may concern Be it known that I, WILLIAM M. ROBERT-l SON, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Dust-Collectors, of which the following is .a specification.
The invention relates to apparatus for separating and arresting dust from air or gas currents, and is designed more particularly for' service in arresting and removing ore-dust from the gases in their travel from the furnace to the acid chambers in the manufacture of sulfuric acid.
The object of the invention is to provide an eflicient apparatus, economically constructed and operated, through which the current is slowly led and so subdivided and baflied in its travel as to form a succession of dead spaces or pockets in which the gas lies practically motionless and favorably conditioned to permit the particlesheld in suspension to settle in open receptacles located in such relation to the dead spaces as to receive .and retain the dust.
A further object is to provide receptacles of such shape and arrangement as to themselves serve as battles in producing the dead spaces, and another important object is to provide convenient and easily operated means for emptying such receptacles and removing the accumulated dust from the apparatus.
The invention consists in certain novel features of construction and arrangement by which the above objects are attained, .to be hereinafter described and claimed.
The accompanying drawings form a part of this specification and show an approved form of the invention. V
Figure 1 is a vertical longitudinal section through a dust chamber of a sulfuric acid plant, constructed in accordance with the invention. Fig. 2 is a corresponding transverse section, taken on the line 22 in Fig. 1, and partly in elevation. The remaining figures are on a larger scale. Fig. 3 is a vertical section through portions of two groups of receptacles, corresponding to a portion of Fig. 1. Fig. 4 is a plan view of one of the receptacles, partly in horizontal section. Fig. 5 is a corresponding elevation, partly in vertical section. Fig. 6 is an end vieW of the same. Fig. 7 is a vertical transverse section taken on the line 7-7 1n Flg. 5, and partly in elevation.
Similar letters of reference indicatethe same parts in all the figures.
A is a dust chamber receiving gas from a furnace, not shown, through a connection B and vertical passage B controlled by a valve B which delivers the gas at a low point in the chamber. After traversing the latter the gas escapes from a low point therein 1nto a vertical passage C controlled by a valve C ,'and thence through the connection C to the acid chamber, not shown, or other portion of the plant. Any parts of the dust chamber not represented may be understood to be as usual. p
The chamber A is divided by a wall A into portions A A communicating with each other at the top of the chamber above the wall or partial partition A At the bottom the side walls of the chamber converge downwardly to a screw-conveyor A,
extending through the partition A arranged to be revolved by any suitable means, not shown, and carry away any dust received at the bottom of the chamber.
It will be noted that the two portions of the chamber are each of very much greater area than the inlet and outlet passages B and C so that the movement of the dust laden gas current is correspondingly reduced in its upward traverse through the portion A of the chamber and its downward passage through the portion A thus affording quiet conditions favorable to the deposition of the dust.
In each portion of the chamber is a group vided tortuous paths provided by the spaces between the troughs, the inclined exterior side faces of the latter serving as angular baffles.
The paths followed by the ascending gas in the portion A and the descending currents in the portion A are indicated by the arrows in Fig. 3, and it will be seen that in and above each trough is I a dead space, marked at a, in which the movement is extremely slow and favorable to the deposition of dust in the trough. The multiplicity of such pockets ofi'ers suflicient opportunity for arresting the dust and when the latter has once settled in thetroughs it is completely out of the current and lies undisturbed until removed.
Each. trough comprises a relatively fixed- "side plate D and a movable side plate D they form an open-topped trough of triangular section, and when the movable plates of any vertical series are swung, as indicated by the dotted lines in Fig. 3, a clear vertical "channel is offered through which the dust collected in that series may fall directly to the bottom of the chamber and to the conveyer A On the interior of the side walls of the chamber are lining plates F F each having openings f f covered by castings G Gr adapted to support the side plates D D of the troughs. Eachcasting has a vertical rib G on its inner face serving as a stop for the adjacent wing D formed on the ends of each movable side plate D and each casting G has a boss G receiving the adjacent trunnion D? on such plate. The casting G has a similar boss G but the latter is 'open at the outer end and the trunnion D projects therethrough and is squared to receive a crank D bywhich themovable plate D may be swung or oscillated from and to the fixed plate. e
Each fixed plate D is supported at each end in the castings G G and is formed with spurs or hooks D D engaged in. corresponding recesses in the castings to hold it in fixed relation to the movable plate.
It will be observed that each movable plate may swing in an are determined by its stop G in one direction and the fixed plate D of the adjacent trough of the next series, in the opposite direction, as illustrated by the dotted lines in Fig. 3, and by successive oscillations of the movable plates against such stop and plate, all are effectively jarred and any dust-bridges broken, and the dust caused to descend. The valves B C are closed, as shown in Fig. 1, during this emptying operation to prevent the escape of dust through the passages B and C, and remain closed until the chamber is cleaned and any remaining dust has again settled.
By removing the outer cover-plate A access is had to the castingsG and by the removal of such castings broken or worn sideplates D D may be readily removed and new ones substituted with little labor or loss of time.
The number and. arrangement. of the troughs may be varied, or their-angularity modified, and other means may be employed for their sup ort, and for the removal of the dust accumu ated therein. The chamber may be equipped with several groups of troughs and arranged to cause the current to traverse them successively, or the chamber and troughs may be arranged to .serve for a. single long traverse.
I claim Y 1. In an apparatus of the character set forth, a chamber, and a group of opentopped receptacles therein arranged in staggered relation, with the margins of each receptacle overlapping the adjacent margins of the pair of receptacles next below, said receptacles having upwardly divergent sidefaces, whereby dust-laden currents between said receptacles are deflected by such sidefaces to produce a dead space in and above each of said receptacles and permit dust to settle undisturbedly in the letter and means for opening and closing each of said receptacles having upwardly divergent side-faces,
