APPARATUS FOR COOLING AND PURIFYING GASESL Application filed. April 25, 1927, Serial No. 186,455, and in Great Britain July 21, 1926.

This invention relates to apparatus for the cooling and purifying or treatment of gases by fluids and particularly to that type using liquid for the coolingand purifying medium in which the is passed through a series of perforated members, alternatively fixed and revolving, and wherein the cooling and purifying liquid introduced and is broken up into small particles bythe revolving mem bers and thereby intimately mixed with the gas; the particles of dust or dirt in the gas are thereby saturated and entrained in the water which is thrown outwardly by centrifugal force, whilst the gas is drawn through the perforated members by a fan or other known means provided for the purpose.

The present invention comprises apparatus for cooling, pu "ifying or treating gases, consisting of one or more pairs of perforated discs of which one member of each pair is fined while the other rotates, the gases being forced or drawn through the perforations in the discs so to be intercepted by transversely moving streams of liquid passing radially between the discs. One or both of the adjacent: surfaces of'each pair of discs between which the liquid passes is or are provided with projections arranged to break up the liquid. i

A manner of carrying out the invention is illustrated by the accompanying drawings wherein Figure 1 is a partly sectional elevation of a washing device made in accordance with the present invention, liigure 2 a side elevation of .liigure 1, Figure 3 an enlarged, view of the main details of the apparatus, Figure -l is an alternative COIlSlTl'llCllOll of the main details shown in Figure 3, Figures 5 and t3 areiront and side elevations of a modified construction of one of the discs and Figure 7 a modification of liigure 5.

In these

drawings

2, and 3, 2" and 8, 2 and 3 are three pairs of perforated discs, 4: being the perforations in thediscs. The

discs

2, 2 and 2", are fixed to a hollow annular member 5 secured. in a main casing (l of the apparatus, while the

discs

3, 3 and 3" areiixed on a rotary drum 7 fixedon a driving shaft 8 and of which the outer end is open, while the inner end is formed as an extension of the boss 9 of a centrifugal fan having blades 10 so that the fan is rotated simultaneously with the

discs

3, 3 and 3".

All the discs have central holes and the 55 drum 7 is of step like or conical formation to take the

discs

3, 3 2tll( 3" which are of gradufrom the axis of the shaft, they may be of any other suitable shape adapted to allyincreasing size, the annular member 5 being similarly stepped to receive

theiixed plates

2, 2 and 2". The dru1n7 is provided with a series of perforations 11 so arranged that as the drum 7 rotates these per'lbrations come oneafter the other immediately in register with a number of :iixed jet nozzles 12 through which is forced washing water or other liquid with which the gases are to be treated. The fixed pipes 12 of the jet nozzles 12 extend into the open end of the drum 7 and the nozzles are arranged to deliver radial jets towardsthe openings 11 in the. drum 7. The annnlaranember 5 is provided with a diametrically oppositescries of perforations 13 which convey the water after it has treated the gases to a waste water pipe 1-l which ortends downwards into a reservoir in which the water is kept at a level 15 to form a water seal over the end of the pipe It.

On the adjacent surfaces of the pairs of

discs

2 and 3, .2 and 3, 2 and 3" are provided a suitably spaced series of projections 16, those on the fixed discs being arranged at radial distances from those on the rotating discs. The projections on the discs may be placed thereon as shownin Figures 1 and 3, or radiating from the centre as shown on the revolving discs in Figure 4; or they may be placed at any intermediate angle as may be found most suitable.

The projections 16are shown inclined away however,

break up the jets of water passing between the discs.

The gases enter the casing (3 through. the inlet 1.) and are drawn through the perforations 4 of the discs by the blades 10 of the fan and discharged from the casing (3 through an outlet 20. a

The series of pairs of discs, 2 and 3, 2" and 3, 2" and 3" are duplicated on the other side of the fun, there being a corresponding inlet 19 to this duplicate series of pairs of discs. A discharge outlet 14, is provided for the washing water, thegas discharge outlet 20 being common to the series of discs on both sides of the fan. The gas outlet 20 provided with a drain pipe 21 extending into the same" reservoir as the pipes 14: and 14:.

Inthe modification illustrated by Figures 5 and (S, the

discs

2, 3, etc, are constructed with a number of uniformly disposed openings 25 in each of which is fixed a meshing 26 formed by interlaced bars or wires.

In v the further: modification illustrated by Figure 7, each opening in the

discs

2, 3,

etc. is covered by meshing 26 heldover the opening25 by bolts 27.

By means of the above apparatus the gas and water are brought-intothorough and inwards until it timate contact during the rotation of the fan by the shaft 8, the apparatus being in a manner similar to a turbine, the fixed discs, 2, 2

and 9 being the stator element while the

rotary discs

3,3 and 3" are the rotary element,

projections'ltl the blades of the turand the bine.

The

discs

2 and 3, 2 and 3 2" and 3" are show-n withprojections 16 on one side only, they may however be provided on both sides anda corresponding additional system of jets and openings provided as'shown in Figure 4;. l/Vhile the discs are'rotatlng the liquid from the jets 12 received by'the inner series of ro- *tating projections 16 is thrown by centrifuprovided with clean water jets, the partly cleaned gas from the perforations 4 of the firstpair is subjected to a second cleaning 'while passing through the perforations of the second pair of discs and so on through the third pair of discs, thereby effecting a most thorough and effective purification of the gases under treatment.

The discs may be made 'in' the form of plates with holes drilled or punched therein and with projections bolted or otherwise secured thereto, or they may have the holes and projections pressed out, or otherwise integrally formed. The discs may if. desired consist of interlaced bars forming a meshing, as has already been proposed in other washers.

The

fixed discs

2, 2 and 2" are secured to a separate ring 5, so disposed that it can be moved within limits in a direction parallel vto thecentre shaft, by means of screws and nuts 6 and 6", by whichlmeans the discs secured thereto may be placed at any desired distance from the revolving discs, and the in tensive washing action of the apparatus increased or'decreased without dismantling.

Thefapparatus may be constructed with one pair of discs where a high degree of cleaning 'isnotdesired, and any number of subsequent pairs of discs may be added to suitthe degree of cleaning desired.

"Instead of constructing the apparatus within the casing of a centrifugal fun it may be constructed within a self-contained chanr ber, and the gas be either forced or drawn through the discs by any known means.

\Vhat I claim and desire to secure by Letters Patent is 1. Apparatus for treating gases comprising a series of fixed annular perforated discs, a series of rotary annular perforated discs, a series of fixed radial liquid jet nozzles, a casing in which the fixed discs are secured and means-for drawing the gases through the perforations in the discs, a rotary stepped drum, the rotary discs being fixed on the steps of the drum, and the rotary drum provided with openings in its periphery arranged over the fixed radial liquid jet nozzles.
