ROTARY scimisiinn AND WASHER;
Application filed June 30, 1924Serial No. 723,391, and in Great Britain J'uly l16, 1923. y
or relating to rotary scrubbers and washers for use in the manufacture of gas and the like, such for instance, as the purification of gas and the absorption of ammonia, naphthalene, cyanogen, and'benzol.
The `invention has more particular reference to washer-scrubbers of the kind in which one or a series of revolving bundles, porous screens, or elements are mounted to rotate within a cylinder or chamber containing the solvent liquid. Heretofore it has been the common practice in such apparatus to work with the liquid level almost upto the central line or bearing shaft ofthe machine, or at any rate, sufficiently high to ensure the complete immersion of the lower sections or .buiidles, and it has also been proposed in such an arrangement to provide buckets on. the periphery of the bundles for the purpose of raising thewater or liquid and causing it to percolatezthrough the upper bundles, the said buckets being provided with perforated walls at their inner sides for this purpose.
The object of the present invention is to provi-de an improved rotary scrubber and washer having increased efficiency and capacity for a given size and which can be used with a less quantity of solvent than heretofore. i v
Now according to the present invention l provide a rotary scrubber and washer of the kind described for use in the manufacture of gas and the like having bundles or wetted elements which are arranged to revolve entirely above or almost entirely above the levelv of the liquid so as to be more fully eX- posed to the flow of gas and a plurality of buckets associated therewith and so constructed and arranged as to dip into the liquid and pick up the solvent and to retain same during the lower portion of their upward travel and to discharge same over the bundles when aty or near the top of their travel. v
In order that the present invention may be clearly understood and more readily carried into eifect it is hereinafter described with reference to the accompanying drawings, in which Y Y Figure 1 is a sectional side elevation'of a single section of a five-bay rotary scrubber lustrating the arrangement. of the buckets in relation to the solvent; f j
F igure 3 is a detail sectional view to an enlarged scale illustrating the arrangement of a bucket on the vperiphery of one of the bundles; i f
Figure l is a similar detail view illustrating one of the bucketsv detached from its bundle; i 1 Figure 5 vis an enlarged end or side tion of said bucket; 1 Figure 6 is a plan view of said bucket, and Figures i', 8, 9 and l() are substantially similar detail views to Figures 3, 4, 5 and 6 illustrating a bucket of greaterv width than the widthv of the bundle to which it is secured, but having a mouth of the same width as the bundle. f
[is shown and" in one convenient lmannerv of carrying the present invention vinto effect the improved machine may be built up in the well known manner in one `or more outer cylindrical casings such as a, having a hori- Zontally arranged shaft t drivenbya suitable engine or gearing and carrying a plurality of radially arranged bundles c of corrugated iron, wood or other suitable or preferred material. The machine may be conelevastructed in one or more sections or casings a inthe well known manner with'one or more intermediate bearings such as d, and may be provided with a connecting pipe e for the passagev of the gas from section to section, i
and each section may comprise any preferred number of bays a a2 t3 a,4 `and a5, as will be readily understood. The buckets f, which may, as shown, be of rectangular or other formation, as preferred, are suitably fixed, as by metal straps g, to the periphery of the circular plates L carrying` the revolving bundles 0, and conveniently one such bucket f would be provided in conjunction with each bundle c. lThe buckets f are so'designed and angu-V larly arranged that they do not begin to discharge their contents'until at or near the horizontal centre line when the buck-ets are vertical, as indicated inFigure 2, and they dis?- chargetheir total contents 'when at or near the top. For instance, the buckets f could be -deep and narrow, as shown, with a relatively small or narrow opening or mouth f at the inner leading edge. Thus in opera-` tion the plates h as they revolve carry with them the buckets f which are so shaped and arranged that they pick up the solvent z in the casingsa at the lower portion of their travel,
and then when at or near the horizontal centre line begin to distribute saine evenly and regularly over the whole surface or the Y for a predetermined length. or time, or partbundles, c.
ly returned to the adjoining compartment of the washer. By this means it will be manifest thatvit is not necessary to provide a large quantity oit solvent e andthe level of the solvent in the washer can be considerably lowered as compared with the present practice, being` inerely up to the underside ci the circular plates Il thus leaving exposed to the 'flow 'of gas the whole ot the wetted area of the The level ot the solvent can be maintained constant by suitably arranging the overl'low pipes from one section to another.
The buckets 7 may, in Figures l to 5, be of the same width as the bundles or they may, as in Figures 7 to l0, be ol' greater width than the bundles. In the latter case the mouth is preferably made of the same width as the bundles,` as will be' readily understood. It will be obvious that the bundles 0 may it desiredbe increased in length towards the shaft always providing` that suliicient space is left tor the passage of gas from one compartment to another; that is to say, a space equal in area to the area of the inlet and outlet gas connections.` The gas enters the machine at the left liant -side of the saine, flows inwardly through the bundle in a, flows outwardly through the bundle in a2, then downwardly on the outside of said bundle in a2 and between the saine and igea-,eea
in 0,37 then outwardly between the wall andY the bundle in a4 and inwardly through the bundle in said casing at, outwardly through the bundle a5 and then escapes through thev outlet on the right hand side ofthe machine.
lt will thus be seen that bythe .present invention it is possible to obtain an increase of incre thanSO per cent of the wetted area eX- posed to ilow of the gas, as compared with present practice; to reduce considerably the amount oi solvent carried in the washer and also the weight ol the'inacliine; to obtain im-V proved wetting ei the bundles with increased absorption results; and also to obtain greatly increased capacity with a consequent proporticnate saving in ground space and housing ccoinmodation.
`What l claim is A rotary gas scrubber and washer, comprising a rotating series oi bundles of elements to Vserve as the carriers ol a solvent for the purifi- TOM JQNoDnN.
