HEAT EXCHANGER.

,application illed August 8, 1921. 'ScriaLNm 499,540.

To all whom it 'may con/cem:

' Be it known that l, JOSEPH F. MUsseL- MAN, a citizen ot the United States, and resi- ',dent-of Bronxvillein the county of West'- chesterl and State of New York, have in# vented certain new and useful Improvements in Heat Exchangers, of which the following is a specification.

My invention relates to the separation from water or similar liquid ofl the dissolved oxygen or other corrosive and inert gases contained therein, and more particulerly to apparatus for such purpose, and

l has for one of its objects the provision of such apparatus having improved means for causing a Vcontinuous circulation of the water.

Another object is to provide means for bathing the water so as to more thoroughly separate `'the air and allow time for its escape. l

Another object is to provide a tank of this class in which the water from which the corrosive and inert gases are to be separated will be subjected to alarger heating surface :than in the tanks heretofore provided.

These and other objects will be more fully kbrought out in the following specification and claims, and illustrated in the accornpanying drawings, in which1 Figure 1 is a side .elevation of the tank.

Figure 2 is a vtransverse section on the line ll-H of Figure 1.

Figure 3 is a sectional elevation, the section being taken on the line lll-III of Figure 1.

Referring to the drawings, the letter A designates the tank in general, which is composed of side walls 2, a'dished bottom 3 and a top t, and supported on legs e". The top ispiovidcd with a centrally arranged in tcrnally threaded aperture 5 surrounded by a shoulder 6. A nipple 7 is threaded into the aperture 5 and carries a screw threaded cap 8 provided with an air escape aper- ,ture 9.

i A diaphragm 10 is loosely mounted on a plurality of spaced angle brackets 11 se- 'cured to the side walls 2 of the tank, thus dividing the tank intov two portions or chambers, the lower and largest being the heat exchanging chamber C, and the upper and smaller chamber, the air separating chamber D.

A baffle ring 12 of less diameter than the tank A, is spaced above the diaphragm 10, and supported by spaced angle members 13 which are secured to the diaphragm.

A manifold member 14, having'a closed inner end and a threaded o uter'end adapted supply, is passed through the side wall 2 ad-I jacent the lowerend of the tank and is held in position by a nut 15 in threaded engagement with the threaded outer terminal.

A pluraltiy of helical coils 16, 17 'and 18 vare arranged within the tank A, each Within the other, the coil 17` being of less diameter than the coil 16, and the coil 18 being of less diameter than the coil 17. i

The coils. 16, 17, and 18 have their bottoni terminals connected to the cold water manifold 14 and their. upper terminals extend upwardly through loose fitting apertures formed in approximately the center'of the diaphragm 10 to approximately the top of the baille ring 12 which marks the water level.

A plurality of circulation pipes 19 are arranged on the outside of the tank A, and have their upper ends communicating with the separating chamber D, through inlets 20, and. their lower ends connecting with the lower portion of the heat exchanging chamber C,- through. inlet 21.

Hot water enters the heat exchanging Ato be connected to-a source of cold water chamber C of the tank A, 'through an inlet 22 arranged adjacent the 'top of said chaink,is suppliedto the tank through the hot water inlet 22, and ilows out to the circulating system (not shown) through the' outlet 23.

Cold water enters the manifold 14 from a source (not shown) and passesupwardly through the coils 16, 17, and 18, becoming heated by absorbing heat from the hot water in the tank, and as the water flows upwardly, the air naturally contained in it 1s progressively freed from solution :in the water in the form of tine bubbles. During the course of upward travel of the water, these bubbles have a tendency to be thrown outwardly, due to centrifugal force caused by the "travel through the coils, and they unite forming larger bubbles which break upon reaching the chamber D. The water after it reaches the chamber D is ballled by the baille ring 12, thus allowing it to remain within the chamber a sutiicient length of time to permit the air to esca be. The water in the two chambers C and D is continuously circulated through the'pipos 19, the baille l2 serving to break up the body of water in the chamber D, and prevent the formation of circulation eddies or zones.

It will be readily apparent from the above description that I have provided an improved apparatus that will more thoroughly separate the corrosive and inert gases from water than those heretofore constructed, and one that will have a more ellicient water circulation.

lhile I have shown and described one particular form of tank it will be readily apparent to those skilled in the art that various changes in design and con'ibination of parts may be made within the scope of the appended claims without departing from the spirit of my invention. For instance, any number of coils may be employed, or the diaphragm 10 may be rigidly secured in place, and the various parts may be. assembled and secured in other ways than described.

In a tank of the class described, a diaphragm for dividing said tank into upper and lower chambers, said lower chamber being provided with hot water inlet and outlet ports for causing a circulation of hot water therethrough, at least one helical coil within said lower chamber adapted to be connected to a eold'water supply and terminating in said upper chamber, and means raeaeee ger causing a circulation between said chainers.

2. In a tank of the class described, a diau phragm for dividing said tank into upper and lower chambers, said lower chamber being provided with hot water inlet and outlet ports for causing a circulation or hot water therethrough, at least one helical coil within said lower chamber' adapted to be connected to a Coldwater supply and terminating in said upper chamber, and at least one circulation pipe extending along said tank and Iconnnunicating with both of said chambers.

3. In a tank of the class described, a dia,- phragm for dividing said tank into upper and lower chambers, said lower chamber being provided with hot water inlet and outlet ports for causing a circulation of hot water therethrough, a plurality of helical coils withinsaid lower chamber adapted to have their lower ends connected by a suitable manifold to a cold water supply, said coils passing' up wardly through approximately the center or said diaphragm and having their upper ends terminating within said upper chamber, and a plurality of circulation pipes extending along the sides ot said tank in suitable spaced relation and having their ends ter'- minating in and communicating with said upper and lower chambers.

4.
