Taal? whQm tn/bay concern.: 'I y v Beit known that I, VV'ILLIAM HENRYBARR, a subject of the Queen of Great Britain and. Ilieland,'residing-at", Bury, iuthe count-y of Lancaster,`England,'have invented certain I newand useful Improveinentsin Methods of andpApparatus for Filtering and Deodorizing Steam,(for which I have made application for patent `in Great Britain, No.` 13,128, dated June 24,'1899,)'of"which the following is a 'speciflcation.,y i y My invention relates toa method of and apparat-us for use in filtering anddeodorizing steam, by means of which exhaust or live steam maybe filtered to remove oily particles,

. moisture of condensation, and foreign mataccompanying drawings show tersA held in suspension'. Further, when required, bad smells due'to hydrogen sulfid or to-otherrvolatile organic substances may be removed and the steam thus deodorized. The the apparatus devised for this purpose. v

Figure l is a sectional elevation ofa single unit apparatus for filtering and deodorizing steam. Fig. 2 is a sectional elevation of .an apparatus suitable for the treatment of very large'yolumes of steam. Fig. 3 is a plan of Fig. 2 with the' cover removed. Fig. 4 is an enlarged detail -view of a portion of one of 30 jshown in Figs. 2 and 3.

the lter-beds employed with the apparatus Referring in l-tllerst place to Fig. l, the apparatus consists of a pressure-proof casing v a, carried by asuitablestand b. A'cov'er c is supplied, secured by means of hinged bolts c', While a dis-k c2 of asbestos provides'a fluid- "tight joint between the lid or cover c and the casing a. Tol'the cov'er c is secured a filterbed d, which consists of a perforated metallic tube. When larger than tw'o inchesin diamstretching process omitted, so that the interstices are reduced in size and at the same time the tensile strength of the cloth bers is The tube d is formed at each endl increased, andthe cloth is thus rendered very suitable as a sti-ainingmatelial. The straining-jacketl is secured to the tube d by means of a cord Wrapped around the grooves d2.

To Iilter the steam, I throw into the bottom of the clean empty casing a a small quantity of porous earth, such as kieselg-uhr or agalite or any other suitable porous land absorbing substance of a likecharacter, sufficient iu A quantity to cover the jacketed cylinder d to the'thickness of from one thirty-second to one-` eighth of an inchl A thicker coating of filtering-earth may be used, but for all ,practical porosity and absorbing powers, but other filtering-earths-such as agalite, chalk, and the So far I have only-provided for the removal ofoily particles, foreign matters in suspension, and moisture of condensation; but when it is desired to remove badsmells from the\'5 steam, due to hydrogen, s-uliid, or to other volatile organic substances, I use about equal proportions of a lterigeartb, such as kieselguhr or agalite, and oxid of zinc or other basic metallic oxid, which is deposited at the bottom of the pressure-'proof casing a, and

During the workingol the apparatus the terebene is'introdnced daily through the cup f, and when required for cleansing `pin-poses thel filter-bed d, attached to the lid,can be removed therewith, so that the cloth strainer' can. be removed and cleansed.

For filtering and deodorizing larger volumes of steam I employ a number of filtering unitsarranged-as shown in Figs. 2 to 4.

I employ any suitable number of filteringcylinders,.according to the volume. of steam to treated, and mount such filtering-cylinders in concentric circles, as shown in the plauvview- Fig. 3, Within avpressure-p'roof cas- `44fing g. The vcylinders deliver thel purified arrangement forsixty-one cylinders.

Thepe'r-forated drainagetubes n serve' to carry and support pervious cylinders'o, a concentric circulating-space being provided by distance-pieces p.
