APPARATUS FOR DEAERATION 0F LIQUIDS.
Application led April 4,
To allfwhomt may concern:
Be it known that I, SELDEN H I-IALL, acitizen of the United States, residing at Poughkeepsie, county of Dutchess, and State ot New York, have invented a new and 'useful Improvement in Apparatus for Deaeration of Liquids, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
The object of my invention is the provision of simple and economical means to remove from' liquids, air or other gases which may have been entrained by agitation, atomization, or from any other cause.
I have 4observed that when liquids like milk, water or oils are discharged from a centrifugal machine, they are broken up into a fine spray and entrain a considerable uantity of air in such very finely divided from the liquid. I have even proven the presence of a large quantity of air in oil that has stood .quiescent for more than half an hour and I have seen milk froth remain in a tank for several hours.
I have devised novel and eifective apparaf tus wherein gassy liquid may be subjected to a partial vacuum, which will cause such expansion of the air bubbles that they`will expand, break and escape, leaving a gas-free liquid. The invention is adapted to the removal of gas from foamy liquids as well as from liquids which, while not substantially foamy, have small bubbles of air entrained therein which are more or `less uniformly distributed throughout the bulk of the liquid. It will be understood that the word gas is used in its physical sense to include air or any other gaseous fluid. It will also be understood that in using the term degasifying I mean to include, as well as defoaming, the substantial removal of gas 1n whatever form it may be entraincd.
The: ldrawings show two apparati embodyi-gmy invention.
Fig. 1 is a diagram, in vertical section, of
one such apparatus, and Fig. 2 is a siimlar view of another such apparatus. v a is a centrifugal machine which discharges into a tank b having an outlet pipe c, the inlets d to which may be closed by a valve e operated by a. ioat f. The pipe c leads to the top of a`- chamber g provided with shallow pans h, through which the liq- 1924. Serial No. 704,280.
uid ilows consecutively, thus being spread 4 lchamber g a pipe Ic leads to a liquid pump p.
The pipe extends up inside the chamber, has its upper end closed, and has ports m 1n its sides that are closed by a valve n when the liquid in the chamber allows the oat o to drop.
When in operation the areated liquid from the centrifugal machine a enters the tank b, where the large bubbles rise to the top. The liquid from the bottom, containin onl smaller bubbles, flows through the 1n ets and pipe c to the chamber g, where it .is spread out in thin layers on the pans h, giving anopportunity for rapid separation of the bubblesgreatly enlarged by the reduction of pressure caused by the vacuum pump j. With a vacuum of 15" of mercury, the bubbles are about twice normal volume; with 22 vacuum nearly 4 times; with 26" nearly 8y times; and-with 28 nearly 16 times normal volume. The above data are predicated on a 30 barometer. The liquid,'freed from air or gas, falls to the bottom of the chamber, raises the float o and valve n, opening the ports m, and then flows through these ports and the pipe lc to the pump p, which forces it to any desired location.
In Fig. 2, which shows another form of apparatus for carrying out my invention, the tank 1', correspondin in function to the tank g of Fig. 1, is p aced at an eleva.- tion, and instead of having in it a number of shallow trays, the tank itself is made long ang wide so as to obtain, ari-equivalent area an whic corresponds to the pipe lc of Fig. 1, is also made so long that, when it is filled with liquid, the weight of the liquid will overcome the atmospheric pressure outside and cause a flow from the tank r. A non-return valve is provided at 't to prevent the entrance of air when the apparatus is being started.
` The operation of the two apparati is the same except that no pump is needed to draw the liquid from the tank (r) in the apparatusshown in Fig. 2.
`In the claims, where reference is made to a high vacuum, yI meanto include a vacuum of twenty inches of mercury. or higher.
provided with a baffle u. The pipe s,
Havin now fully described my invention, what I c aim and desire to protect by Letters Patent is:
1. Apparatus for degasifying liquids comprising a. preliminary tank provided with an inlet to receive the liquid to be degassed and an outlet for the esca e of such liquid, means adapted to close sai outlet before the level of liquid in said tank falls to the level of said outlet, a second .treatin pipe connecting said outlet with the second chamber, means to maintain a high vacuum in the second chamber, means rovidin a. passage for the' withdrawal of egassed fiquid from the second tank, and means preventin the escapeof gases with the withdrawn iquid.
2. Apparatus for degasiyingli nids comprising, in combination, two tan s, pipes chamber, a
extending upward into the respective tanks 20 and adapted to communicate respectively with the same below the liquid leve s therein, float-controlled valves, one for each tank alxlapted to shut oil' communication between t e when the leve of the liquid drops below a redetermined height, the pipe communicatmg with the first tank communicating also with the upper portion of the second tank,
ody of li uid in each tank and said pipe 2 means within the second tank and above its 30 bottom portion adapted to spread the liquid in a Arelatively thin layer over la. relatively large area, and a vacuum pump communicatwith the second tank.
n testimony of which invention, VI havey 35 hereunto set m hand, at Poughkeepsie, on this 31st day o March, 1924.'
