'1 Claims. (Cl. 261-89) This application relates to apparatus for cleaning and tempering air for ventilation purposes by bringing it into intimate contact with fresh water, and my object is' to devise apparatus for this purpose which will effect an efiicient multistage intimate contact'between the water and air without excessive height of apparatus and in which the conditioned air is efiectively freed from entrained water as it passes from the apparatus.

The invention is hereinafter fully described and illustrated in the accompanying drawings in which Fig. 1 is a vertical section of the improved apparatus; a

Fig. 2 a section on the line 2-2 in Fig. 1; and

Fig. 3 a section on the line 3-3 in Fig. 1.

In the drawings like numerals of reference in-- dicate corresponding parts in the different figures.

The apparatus as far as its basic features are 2 concerned comprises a casing I through which air is caused to flow from the bottom to the top, on its way passing through successive disk shaped sprays of water. The water thrown outwardly in any one spray contacts with the wall of the eas- 05 ing,-is collected and led to the axis of the casing to be again thrown out in a spray one step lower and so on.

The treatment is thus in a plurality of stages. As head room is usually limited it is necessary to cut down the height of each stage asmuch as possible without. sacrificing efllciency, and to cut down the resistance to air flow as much as possible. This result is attained by the construction which I will now described.

A shaft 6 is vertically journalled in the casing I and may be driven in any suitable manner.

To this shaft are secured a series of equally spaced slingers 5 whose function is to throw water in a radial spray outwardly against the casing l.

Plain disks are not effective as the friction become the first mentioned defect, but it is not possible to put enough vanes on a disk to give a sumciently large number of fine Jets. I overcome the difllculty by' forming the slingers as circular bristle brushesjthe bristles of each of which are substantially in contact to form a radially ribbed resilient disk which readily imparts a whirling 66 motion to water dropped upon it, and discharges it in a multitude of fine Jets between which the air will flow in fine streams. The bristles of the slingers may be of organic material or of metal.

. Below each slinger an annular'trough 3 is $8- cured to the wall of the casing. The inner wall of the trough is eccentric to its outer wall, thus forming an eccentric waterway, widening towards that side of the waterway from which leads the spout 4. Conversely, the waterway of the trough decreases in cross-sectional area each way from the spout 4 which is substantially U shaped in cross-section. The capacity of the trough thus increases near the discharge spout which facilitates flow to the spout. Such a trough allows a maximum space therethrough for the passage of the air, and as the spout adjacent the trough has substantially as great capacity as the trough, friction is kept down to a minimum and the spout need not be inclined 20 downwardly, the hydraulic gradient of the surface of the water being sufficient to eilect discharge. Referring to Fig. 1 it will be noted that the top edge of each trough is below its slinger to catch the water thrown thereby and that the 25 I bottomof the discharge end of each spout overlies the next slinger so that the water thrown by one slinger is fed to the next slinger. The bottom of the discharge end of each spout is in a plane close to a plane passing through the top edge of the trough to enable the slingers to .be spaced as close as possible. The portion of each spout connecting its discharge end with a trough may be inclined to increase the cross-sectional area of the spout so that it will be substantially the same as that of the trough at its point of connection therewith. In other words, the depth and width of the spout at this point will agree with the depth and width of the trough at the point of connection. 0

It will be seen on reference to Fig. 1 that the inner wall of each trough slopes outwardly from the top to bottom so that water dripping down the wall of a trough is caught by the trough next below and is fed to the corresponding slinger. It should also be noted that while the preferred form for the troughs is to make each trough a circular annulus in plan, other forms are possible whereby the waterway of the trough inthus enabling me to get a suflicient number of stages within the head room usually available. Further it follows from the eccentric design of the water trough that a maximum area of air passage is provided through the trough relative to the liquid flow capacity of the trough.

The casing l is supported on a pan 2 which is of greater diameter than the casing so as to catch any water of condensation which may drip from the latter. The lower end of the Shaft is secured to the rotor of a pump I0 into which water from the pan 2 may flow.

A pipe 9 connects the outlet of the pump with the inlet [2 leading through the casing above the top trough 3. This inlet might however be directly connected to any outside source of supply.

The pan is provided with an overflow ll. If the pump circulation be employed make-up water may be added to the pan from time to time.

Near the top of the casing a fan 8 is secured to the shaft 8. Water laden air passing up to the fan is thrown outwardly against the casing and is then directed inwardly again by the frusto-conical flange I3. An inwardly directed flange I4 is positioned just below the fan blades.

From this it follows that air flowing centrally up the apparatus is thrown outwardly adjacent the top of the apparatus thus losing velocity which gives any water entrained therein the opportunity of dropping out by gravity and being returned to the interior of the apparatus by the flange l4. i

The shaft is shown as being driven by the motor l, the shaft of which carries a pulley i5 belted to the pulley l6 secured to the shaft 6. Obviously other drives might be employed.

It will be distinctly understood that this apparatus may be used for purposes other than conditioning air, for instance it may be used to bring other gases and liquids into intimate contact for various purposes, to separate solids from gases by cleaning the gas or reclaiming the dust, to condense liquids out of gases, to evaporate liquids into gases, to transfer heat from gas to liquid or vice versa, to effect chemical reactions between gas and liquids, or to evaporate one liquid from another liquid without boiling.
