To all whom it may concern: y l
Be it known that I, Lawrence Anbsasox, a. citizen of the United States and a resident of Chicago, in the county of-Cook and State of Illinois, have invented certain new and useful Improvements in Dust-Se arators; and I do hereby declare that the ollowin is a full, clear and exact, description tiereof, reference bein had to the accompanying drawings, an to the letters of reference marked thereon, which form a part of this specification.
This invention relates to an im rovement in dust separators and consists o the matters hereinafter describedfandmore par-' ticularly pointed out in the appended claims.
My improved dust separator 1s adapted for the separation of dust, dirt, cinders, or other particles heavier than air from a gas or from air which is driven or drawn through the separator in a current flowing at a rapid rate and dependsfor its 0 ration upon the centrifugal force deveoped by the rapidly movin current of gps'or, air. while passingthrougi the separa r,
My ust separator is shown herein moonnection with'a system adapted. to collect and store for commercial purposestbe 'fuel gas given ofi'.,as a by-productbyua blast furnace and is'desi ed to ;extract.the' cin ders, dust and dirt mm the said fuel see as to make it suitable for use for lig t-iug and heating and power purposes In the drawin Figure 1* is a view. representing in si e elevation -my improved dust separator and a blast furnace to which i is connected. Fig. 2 is a view representing a section through one. of the spiral coils comprising m improved separator, the section being ta on in a plane indicated by the line 2-2 of Fig.1. lFi 8- is a view representing a section of anot er of said spiral coils in a plane indicated by the line 3-8 of Fig. 1. Fi .4 is a view,

Fig..5 isv a view representing a "cross v sect1on through the spiral coil shown in, F1 Lina, lane; indi cate lliy,;the. l1no.5 ;6 t ereotfla. ig. detail, sec ional view.',on an. showing'pne1ofythe,sprayc zal c imbe a .Iie et insimai ateaarm is" e e ar ed as m ent of m invention illustrated in the drawings, indicates a blast furnace of familiar construction which is adapted for the delivery of fuel gas, its by-product, throu h ipes a, a connected to the stack 13 of sa1 urnace.
0 indicates my improved dust separator, as a whole, the said separator havmg one end 0 connected to the pipes a, a leading from the stack of the furnace and being adapted for the iassage of gas therethrough. The other end Y of said separator may be connected directly to a gas reservoir or storgge tanky'o r in case a more refined product is required for the purpose to which the ms is to be put, it may be connected to 0t 101 gas washers or purifiers in which the gas is urther washed and purified.
The separator consists of a metal pipe 0' of comparatively large cross-sectional area, and havingthe form of a helical coil with a plurality of convolutions F. The pipe 0' may be of an convenient form in cross section and, as 8 Own herein, is circular in cross section. .The force of the blast from thefurnace drives the s through the convolutions of the helica coil comprising the separator in a stream which flows at a rapid rate, the gaswhirling about the central axis of the said" helical coil as itv advances through-[the separator,
The" process carried out in the separator in extracting the dirt, dust and the like from the sis threefold and in that embodiment. of, t e invention shown herein, is divided into three so arate stages which occur in succession. n the first stage, the gas is subjected to a process of dry separation; in the second stage, the gas is washed and may be said to. be subjected to a process of wet separation; and in the third stage, the gas is su ectedto a deh drating process, that is tosay, a process or the extraction of the water from thegus. The several stages of the threefold roccss depend for their 0pgifati'on upon-t 1e centrifugal force developed ln thejdust, dirt and water particles carried ",".-:f,j,l o,,carryjout' the threefold process in the it clsuccessive stages above referred, to,
'the bbnvolutioiis of the helical coil Carc into three sets, each set, as shown herein, ineluding" ioprteonvoiutionsa wt in.-. d cates theconvohitlons o! the first set; 0" the convolutions of the second set; and a", those of the third setea-Amshown-in the drawings, the convolutions are formed from a single metal pipe. The body of each con-"- volution is an inte ral part of said pipe, and in this respect t to construction -andcon-* ncction of all the convolutionsotone set are alike. The convolutions'of the first'set. are alone lined with a heat resistingmeans, such as fire-brick or tile, for thepurp'ose, as hereinafter described. As the body of each convolution of all the sets are-made'of metal, a descri tion of one of each set will suiiice for a1 Each" of the convolutions 0' of the helical coil is provided with a fire brick or tile lining D (see Fig. 2) to protect the metal wallsof the pipe (1', since the gas whenit firstlenters he separator from the blast 'furnace is ve' hot."'At circumferentially spaced points m the outer peripheral wallofthe convolution" 0', that is to say, that part of the'pipe wall 'whichl is located at the greatest ra ial distance tram the central axis of the 'helica lcoil, are located o'ckets or chambers d, said pockets or cham rs opening into the interior of the pipe in a direction opposed to the direction m which the as is fiowing through th'e'convolution of t e'helical ipe as indicated by the arrows to in Fi ihe pockets'or c ambers on either si e 01 the convolution o' are connected 'with'api ed, each 3mg s leading to a common disc arge pipe N shown in the drawings the'pipes are provided with branches dfeach ofwhich has an open end projecting into the p1 e C, and constituting the pocketor eham erreferred to; The "ends of saidbranches are turned so that they are directed opposite to the direcion of flow of the gas through the convolution of the helicalcoil. i
The operation as'the as passes throu h the convolutions ois as ollows: Under't e force of the draft from the f urnace, the gas delivered thereby passes through the convo-' lntions of the coi in the direction of the arrows at a very rapid rate, and owing to the centrifu al force developed by this circular flow 0 the gas, the heavier particles of cinders and dirt arethrownoutwardly against the outer eripheral wa'lls"ofjthe convolutions a. T e heavier. particles' are thus carried along in contact wlth this buter peripheral wall until-they reach oneotthe pockets or chambers d n whichth'e 1am arrested and from which they passin o the ipes 'df {and thence intd I the comrnjonfdw ivery' p1 "d". As shown;irr'tlie' drawings, thobrane cs d'otthe i as d3 copstitnting' the pockets, are so curve at dullt'apd cinder par icleswill strike against that'i-walli-of-t into a trough the; is as follows:

Enough convolutions are included in this first section of the helical coil, so that practically all of the larger and heavier particles of cinders and dirt will have been removed from the gas after they have passed throu b said section of the dust separator. "Eac of the convolutions c of the helical coil, comprising the second section of the separator, is provided with circumferentially spaced pockets or chambers f in its outer peri heral wall similar to those provided m t e convolutions c' of the first section, said pockets or chambers being in like manner connected with pi 788 f leading to a common discharge ipe which empties into the trough E an is sealed by the water therein. As before, the pockets or Cillllllbars are' formed by branch piges f connected with thepipes f.

The pleats J provide a space J next to the outer peripheral wall of each convolution c" containin a body of as that is practically unaffecte by the rapi 1y moving current of as in the interior of said convolutions. A ischarge pipe K connected with the lowest part of the convolution, leads down to the trough E and is sealed by the water therein, as in the case of the other discharge pipes. As the gas passes throu 11 this section of the separator, the finely ivided particles of moisture carried in suspension therein, being heavier than the gas, are thrown by centrifugal. force against the plates J and to some extent through the a ertures between the sides 0:! the lates an between the ends of the plates an the wall of the convolution c". The water accumulating on the plates J, and on the walls of the coils, enters the space J and bein there unaffected by the main current of t e gas, flows by gravity through said space and along the outer peripheral walls of the convolutions into the dischar e Pipes K whence they flow into the tank 0 gas when it passes through the outlet end of the separator is comparatively cleanand free of moisture. From the separator-it may be led directly to a place for consumption, maybe conducted to storage tanks or may be directed through other ap- "paratus adapted to further free it from impurities as may be done when the gas is to beused' in explosive engines for power purposes. At the top of each turn of the spiral "I provide a manhole L closed by a gravity controlled hinged ca L which is weighted and serves as a safety valve in case, through the entrance of am with the gas, an explosion occurs, or for any other reason a pressure higher than that desi ned to be borne by the iple comprising the elicalcoil is develope t erein. In each of the pipes f, draining the sections 0 of the sp1ral,I preferably provide a hand-valve f, by means of whichsaid pipes may be closed so that if desired one or more of the sections cflmay-ibe allowed to become partially filled with .water to provide a water seal to prevent a back-flower the gas from the storage tanks, or other parts of the s stem supplied by,-;thedevice, in case it is esired to open up'the blast furnace or for any other reason.
