LIQUID AND GAS CONTACT APPARATUS.

This invention pertains to liquid and gas contact apparatus and has to do more particularly with the means employed to eliminate the moisture from the gas prior to its 15 leaving the apparatus.

More specifically," the invention pertains to an improved construction of the moisture eliminator wherein the gas as'it passes from the zone of contact with liquid is caused to take a somewhat circuitous path and is there brought into intimate frictional contact with a series of plates or a series of wires, or both, whereby substantially all entrained moisture will be removed and returned to the apparatus.

One embodiment of the invention-is illustrated in the annexed drawings, wherein:

Fig. 1 is a vertical sectional viewof. the upper portion of so much of a scrubber as is necessary to an understanding of the invention;

Fig. 2 a transversesectional view on the line 11-11 of Fig. 1;

Fig. 3 an enlarged vertical section of the eliminator proper; and

Fig. 4 a detail perspective view of the wires employed in or used as the eliminator.

The eliminator for the purposes of description is shown in conjunction with a liquid spraying element of the Feld type but it is to be understood that it is in no wise restricted thereto and that the eliminator may be used in connection with any type of scrubber.

In the drawings, 1 denotes the shell or casing through which extends a vertical shaft 2 adapted to be rotated by any suitable means (not shown).

Secured to the shaft is a series of inverted 4o frusto-conical pumping and spraying members 3, the outermost one of which adjacent its upper end is perforated. Said members at their lower ends extend down into the liquid within a pan or receptacle 4 and serve to withdraw the liquid and to spray the same outwardly toward and against the inner wall of the casing. Such sprayed liquid is returned to the pan 4 by an annular downwardly inclined shelf or deflector 5 extending around the interior of the casing. Liquid is introduced through a suitable pipe 6. The construction above described is typical of the well known Feld scrubber but as will be evident, anyother means for securing an intimate contact between the sprayed or which is projected laterally by the pumping, and spraying elements 3, and thence to a. centrally disposed port or passage 7. Said port or passage is formed centrally of an annular plate 8 which inclines downwardly from the center port and is secured at its outer edge to the inner wall of the casing. The plate in effect forms the bottom of the eliminator chamber, while the upper section'of the easing forms the outer wall of said chamber,

said section being surmounted by a top or cover plate 9. An exhaust port 10 extends through the side wall as indicated in Figs. 1 and 2.

' Extending upwardly from the inner edge of plate 8, say for approximately half the extent of said edge, is a plate 11-,- said plate being fastened to the cover 9, and at one end,'see Fig. 2, being deflected laterally and extending to one side of the gas exhaust port 10. There isthus produced an eliminator chamber of tunnel form communicating at one end with port or passage 7 and at its opposite end with exhaust port 10.

Any gas forced through the scrubber must of necessity pass through the eliminator chamber to port 10 and durin such passage it is desirable, to denude it of a 1 liquid which it may carry along. To that end there is mounted within the chamber a series of vertically disposed spaced plates 12, the plates by preference (see Fig. 3) being held in such spaced relation by top and bottom plates 13 and 14 to which they are secured. The plates are curved to conform to the cross section of the casing and partition plate 11 and may be assembled as a unit and placed in position as such.

While such plates will be found all sufiicient under ordinary conditions to elfect the removal of the moisture from the gas by reason of the frictional contact between said plates and the plates, I may position between the plates a gas passing between the series of vertically disposed wires. This may be readily accomplished by tying together a series of vertically disposed and spaced wires 15 by means of horizontal strands 16 and cross ties 17, the arrangement being the same at the top and bottom (see Fig. at).

Said fabricated wire structure may be placed in the spaces between the contact plates 12 and held in such position by crossbars 18, Fig. 3, secured to the plates. Wires thus positioned will of course break up any be seen upon reference to Fig. 3, the exhaust gas is caused to flow in a constantly changing direction by reason of the fact that the eliminator chamber and the plates therein are curved; hence a greater frictional contact inheres than would obtain were the tunnel or chamber straight.

What is claimed is:

In an apparatus of the character specified, the combination of a casing; a laterally curved chamber located at the upper portion thereof and in communication at one end with the interior of the casing through a passage extending centrally of the casing, the chamber at its opposite end being connected to a discharge port; a series of vertically disposed plates arranged in spaced relation within the chamber; and a series of 'ver tically disposed spaced wires located between the plates.

In testimony whereof I have signed my name to this specification.

WILLIAM JOSEPH MOGURTY.
