. 7 Claims. 1
This invention relates to an improvement in a method and apparatus for cooling fluids.
' One of the objects of my invention is the provision of means whereby the fluid to be cooled is successively cooled by both air and vapor cooling means.
Another object of my invention is the provision of means whereby air is first passed over a set of conduits through which the hot fluid to be cooled is delivered, whereby the temperature of the air is raised, and then passing the heated air over a second set of conduits to which the fluid is delivered from the first set of conduits over which water for vaporization is passed, whereby the rate of vaporization will be increased.
Another object of my invention is the provision of means for wetting the second set of conduits over which the heated air is passed.
A still further object of my invention is the provision of means for continuously delivering water to the second set of tubes as well as the air which is passed over both sets of conduits.
Having now described, in a general way, the nature and purpose of this invention, I will now proceed for illustrative purposes to a detailed description of preferred embodiments thereof with reference to the accompanying drawings, in which:
Fig. l is a vertical section through one form of apparatus for cooling fluids;
Fig. 2 is a sectional plan view on the line 2-2 of Fig. 1 of the greater portion of the appara- Fig. 3 is a view similar to Fig. 1 showing another form of apparatus for cooling fluids; and
Fig. 4 is a sectional plan view on the line 44 of Fig. 3 of the greater portion of the apparatus.
Referring first to the construction shown in Figs. 1 and 2, the apparatus comprises a, casing having an upper head ill, a lower head l2 and a cylindrical side wall l4 between the heads, which is provided with a plurality of perforations [5 through which the air passes to the apparatus while the upper head it is also provided with a plurality of perforations 15 through which the air passes from the apparatus.
Located within the casing are two outer coils a and b of tubes and three inner coils c, the tubes of coils a and b being encircled with heat transfer fins l8, and may be supported in any desired manner, the supporting means being omitted for clearness, the convolutes of adjacent coils being in staggered relation to each other.
Supported within'the head") is an annular 2 channel member having an annular flange 20 connected to the side wall of the head ID, an annular flange 22 concentric with the flange 20 and a perforated web 24, there being an annular water trough 25 formed between flanges 20 and 22 to which water is delivered as hereinafter described, and from which trough water trickles in a continuous manner over the inner coils 0f tubes 0. The lower head [2 is arranged to form a water receptacle to which water is supplied through an inlet pipe 26, the flow thereto may be controlled by a valve in the pipe 26, or it may be controlled by means of a float. The level of the water is maintained by means of an overflow pipe 28 to which is connected a drain pipe 30 having a valve 32 for emptying or flushing the water receptacle.
Extending upwardly from the bottom of the lower head I 2 is a tubular extension 34 which extends to a position somewhat above the water level in the head I 2. Rotatably mounted in a supporting bearing (not shown) in the tubular member 34 and a bearing 36 connected to the head I0, is a shaft 38 having a motor 40 connected to the lower end thereof.
Mounted on the shaft 38 is a fan 42 for drawing air through the perforations l5 over the coils a, b and c, while water for keeping the tubes of coils 0 wet is delivered to the annular trough 25 in the head In, is supplied from the water receptacle in the head l2 through a plurality of tubes 44 connected to the shaft 38 by means of rods 46 at the upper and lower portions of the tubes 44. The tubes 44 are placed diametrically opposite each other and are of the same weight and bent exactly alike so as to be in balance with each other and contain the same amount of water which enters the lower ends of the tubes which are curved in the direction of rotation of the shaft 38, as shown at 41, which act as impellers to force the water through tubes 44.
In order to break up the direct flow of air passing over the tubes of coils a, b and c, an annular slotted baffle 48 surrounds the water tubes 44 concentric with the axis of the shaft 38 within the coils, and forms a cylindrical flue for the air extending in a vertical direction substantially the full height of the coils.
The fluid to be cooled enters the outer annular coil of air cooled tubes at at 50, passes downwardly through coil a, passes from the lower end thereof to the lower end of the coil b, through a U-shaped connection 52, then upwardly through coil b, the upper end of the coil b is connected to a header 54. The three coils c are connected at their upper ends to the header 54 and at their lower ends to a similar header 56 having anoutlet pipe 58 connected thereto.
During the operation of condensing a gas or cooling a liquid, the fluid is passed through the successive coils a, b and c from inlet 50 to outlet 58, and during its passage therethrough, water is continuously fed to the trough 25 in the head l0, which wets the coils c by trickling over the coils while air is drawn in through perforations I5, which is heated by contact with the coils a and b and the heat transfer fins [8, partially cooling the fluid passing through coils a and b, and the fluid is finally cooled by the evaporation of the mosture from the coils c by the heated air passed over coils a and b, the air passing through the perforations 16 in the head It.
When condensing gases, it is desirable to re: move the condensate from coils a and b by bleeding the condensate from these coils directly to the outlet 58 by means 9; a trap to connected to th l-lrs ed connec ion cr wded w th 11 alve 52 therein whe eb he low t r u h the t ee 5 lee p t o t i liquid i pas e t rees-i the ap r tus i er oo in h t l u e h wn inF ss- .3 en eemsriees substantia l the sa e lem nt h wn in F 1 an 1 e cep t e m an e b ed n l quid free; t ai oo ed o l an hic the :i ew o ai is e ersed as el as the a p el d nd a r cooled cells- In Fies- 3 a a t e sam ie en eh e ere ha e b en a l e t th m element a i i 1 nd? i h i i' i e a d he end of the h ad i s ne e teii er the inl o th ai hile th a s es eut t ou a ou t .H in t e s e wel W o he eatin Ihe flange -25 of the trough 25' is Secured to he e d p o o th hea H1 at the c t e e 91 the perforated portion of the head 13' and iiorrns an inlet ior the air passing to a squirrel cage fan t? which forms aslotted air due within the coils substantially the full height of the coils, wh e th er :fle iee :23 forms a partition .-l etween the inlet and outlet of the ian.4 2, the air 21111512 p sa e iremth et O t tem t cas n fi t pass s e i e e ce a an b and he e the :wet eei e w i a ke t we ted by water tri klin rom tliet e eh Z5- El e water from the receptacle in head L2 is d ver d to the tr u 5 h ou h etube 45 and dieme ic y ppes te es 4! e nd n redially therefrom.
