ROTARY GAS-SCRUBBER.

SPECIFICATION forming part of Letters Patent No. 444,300, dated January 6, 1891.

Application iiled July 12,1890. Serial No. 358,492. (No model.)

To @ZZ whom it may concern:

-Be it known that I, WILLIAM MooNEY, of North Plainfield, in the-county of Somerset and State of New Jersey, have invented a new and useful Rotary Gas-Scrubber, of

which the following is a full, clear, and exact description.

This invention relates to improvements in gas-scrubbers of the rotary type wherein the gas is introduced and made to impinge on wet surfaces to remove impurities.

My invention further consists inthe construction and combination of parts, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a portion of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation, partly sectional, of the scrubber, showing one division or compartment of the casing provided with dashers revolubly mounted upon a center shaft. Fig. 2 is a partly-sectional plan' view taken on the line 2 2 in Fig. 3. Fig. 3 is a transverse section with the dashers removed, taken on the line 3 3 in Fig. 2. Fig. 4 is a longitudinal section'of one gas-compartment in the scrubber enlarged, taken on the line 4 4 in Fig. 5. Fig. 5 is a transverse sectional elevation of one segmental portion of a washer-compartment in the scrubber; and Fig. 6 is an enlarged broken sectional view of two dashers and spindles between the dashers, showing the relative position of the spindles with regard to the perforations in the dashers.

The outer casing of the scrubber, as shown, consists of a rectangular tankA and a coversection A', having side wings or extensions C, which extend along the sides, which wings are connected by a segmental top or cover e. The casing is divided by transverse partitions g into equal-sized compartments D, the partitions extending across the wings C and being provided in the wings with openings p at alternate ends nearly the size of the crosssection ot' the wing. At diagonally-opposite corners of the casing the wings are provided, respectively, with an inlet and an outlet opening F and G.

As shown, the casing consists of a baseplate, to which are secured the end pieces g and the sectional side pieces g2, provided with side flanges d2, a marginal flange c extending around the upper edges of the end and side pieces, these parts forming the body of the tank A. The partitions g are secured to the base-plate and between the flanges a2, and in marginal contour conform to the cross-section of the completed casing. Upper end pieces g3 complete the ends. Angle or L-shaped pieces 6o d', provided with flanges c2, rest on the tlange c of the side pieces g2 between the partitions g and between the partitions and end pieces. Segmental cover-plates e., flanged and united at e2 and provided with straight end portions 65 e', rest on the upper flanged ends of the anglepieces c between the partitions g, the whole being secured together in any suitable manner; but the casing may be constructed in any approved manner.

A shaft B,supported in brackets d, secured to the ends of the casing, extends longitudinally of the casing about centrally thereof, passing through stuffing-boxes a ine the casing ends to preventpthe leakage of gas, and -7 5 through thimbles d3 in the partitions g. The shaft is provided at one end with a drivingpulley B. On the shaft B between the partitions are xed hubs h, having polygonal rims h', which each support two parallel 8o spaced disks close to the partitions g, which disks are provided on their inner sides with radial ribs t', the pair of disks in each compartment forming a hollow wheel fitting closely in the compartment and adapted to revolve therein.

The hollow wheels support segmental scrubhing-frames I, consisting of segmental side plates t2, adapted to fit between the ribs t", and of perforated flasher-plates m, preferably 90 of Wood, parallelly arranged and extending between the plates i2 at right angles therewith, as shown. The .perforations m of the dashers m are arranged in spaced rows, and between the dashers aligning the perforations therein are arranged rows of spindles n, held in the plates 112, so that currents of gas passing through the perforations m will impinge upon the spindles and. be divided, as shown in Fig. 6. A

At a proper point, preferably on one end of the casing, is a water-inlet pipe H, said pipe IOO being bent to produce a trap to prevent escape of gas, and at the opposite end, at a point aligning the bottoms of the openings p in the partitions g, is a trapped outlet-pipe I', by which location of the outlet the tank A will be kept full of water.

The shaft B, with the wheels carrying the scrubbing-frames, being revolved, gas entering the scrubber through the inlet-pipe F traverses the first compartment D through the revolving wheel in lthe direction of the arrow y. It then passes through the opening p in the first partition into the second compartment D, passing through the wheel in said compartment in the direction of the arrow ywhence the gas passes through the remaining compartments in the direction of the arrows l, 2, and 3.

The gas in its passage through the perforations of the dashers ot' the scrubbing-frames.

and against the4 spindles, which are all kept wet by their immersion as the Wheels revolve in the water in the tank A, will be thoroughly purified, and as the peripheries of the. wheels closely t the top or cover of the casing the gas is compelled to pass through the scrubhing-frames.

By the frictional contact of the gas with the wet scrubbers tarry matter not previously7 taken out will be mechanically removed, and atthe same time any ammonia and carbonio acid remaining in the gas will be taken up by the water.

From the peculiarconstruction an d arrangement of this device it is apparent that alarge frictional area is afforded tor impinging contact of the gas, as the gas enters and passes, through the revolving scrubbers at right angles to their axis of revolution.

While it is preferred to use the spindles n, they may be dispensed with, and an increased number of dashers m be used with good results. I

Having th us described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In agas-scrubber, ascrubbing-frame consisting of two parallel-spaced segmental plates i2, a series of transverse parallel foraminated plates m, and a series of rods or spindles between each pair of foraminated plates and in line with the opposing perforations m m therein, as shown and described.

2. A gas-scrubbing machine consisting of the tank A, having a curved top A', opposite longitudinaliy-extending side wings or eXtensonsC, transverse partitions g,confo1;m ing in marginal contour to a transverse section through said tank, top, and wings and having openings, p at alternate ends Within` said wings or extensions, inlet F and outlet G, a longitudinal shaft B, and scrubbingwheels. on the said shaft, one for every compartment, and each consisting of two circular plates t' t', having radial ribs t" t, segmental frames seated between plates 'L' on said ribs and formed of parallel segmental plates, i?, transverse parallel foraminated plates m,y connecting the plates t2, and rods or spindles n, between the foraminated plates and in line with their opposed apertures, the said wheels fitting closely the sides and curved top of the several compartment-s, substantially as set forth.
