FARBENIND USTRIE AKTIENGESELL SGHAFT, OF FRANKFORT-ON-THE-MAIN, GERMANY, A CORPORATION OF GERMANY ArrARA'rUs non connmrsmo connnnsentn muons Application filed November 20, 1928, Serial No. 320,686, and in Germany November 29, 1927.

The present invention relates to apparatus by surrounding the opening of the vapor supfor condensing condensable vapors without noise by direct contact with liquids.

All the formerly used apparatus which have served to blow vapors into a liquid for the purpose of condensing the vapors or for warming the liquid have the disadvantage of producing loud noises and concussions. Also the known apparatus in which the vapor stream is broken up through sieve-like perforated exit pipes, or by surroundin the vapor exit with layered, more or less 'nely divided substances, have not succeeded in the main purpose of removing the noise.-

l't has now been found that the lack of success of all these apparatus is due to the fact that on the one hand-they do not avoid the release of vapor bubbles from the supply openings, and on the other hand, at the surface between the vapor and the liquid a layer of hot liquid is formed. which, at first, prevents the further condensation of the vapor, so that the following vapor presses the liquid forward until suddenly, from any side, cold liquid enters the Vapor space, causing the sudden explosive-like condensation of the vapor, so that the surface of the liquid continually undergoes a violent pendulum-like movement.

According to the present invention these disadvantages are removed by introducing the stream of vapor into the liquid stream 111 such a way that the vapor and the liquid are combined in an even-flowing downward.

stream. This results in forming a vapor bubble at the opening of the vapor tube, the surface of which functions as acondensation surface from which the condensation product as well as the warmedliquid continually flow 01?. The downward flow is necessary because otherwise the vapor bubbles are released frolnthe opening of the :va or tube by their own buoyancy and are shown to be 'well to support the vapor bubbles ply pipe with a loosely packed solid material of any sort, for example, spheres, Raschig rings orgravel. The capacity of this'appa ratus may also be increased by the combination of several vapor supply openings or pipes in one apparatus.

An embodiment ofour invention is shown in the accompanying drawing, but it is not restricted to the particular 'form shown therein.'

The vapor entering through the blast pipe 1 is carried to the nozzles 2 which are, in this case, attached to a partition or tube sheet 3. The water flowing in through the blast pipe 4 is forced to combine with the vapor strea1n ing out from the nozzles in a downward-flowing'stream. This occursin the illustrated apparatus because the vapor nozzles pass through the holes 5 in a partition wall-6, so that the water exit surrounds the vapor nozzles in the shape of a ring. In order to prevent the vapor bubbles from being torn from the nozzles by the whirling of the water, the

space about the nozzle openings is filled up 1 with broken up material in the form of spheres 7 which, contrary to the many known,

I applications in which they' are supposed to effect a breaking up of the entering vapor watermixture, support the permanent vapor bubble.

This supporting of the bubble of steam is performed in the following manner: The bubble, which is in a labile equilibrium on the opening ofthe pipe, is prevented by the loosely packed material from suddenly turning aside under the influence of whirlings of the water current and from detaching from the opening of the pipe. This effect of supporting the bubble and diminishing the movements of the bubble, is principally section, caused by the filling material. Through the pipe 8 the warmed water leaves the apparatus.

We claim: 1. An apparatus for condensing condensable vapors by direct contact with liquids comprlsmg a container, a horizontal partition in the upper part of said container provided with one, or more holes a vertical pipe passbased on the narrowing of the cross ing through each hole and spaced from the si es thereof, said pi es communicating with a vapor supply at t eir upper ends and at their lower'ends opening into the space beneath the said partition, means for feeding liquid into the space above said partition, meansfor wlthdrawing liquid from said con-' to said space, a second horizontal partitlon spaced below the first partition and provided with one or more holes, a vertical plpe communicating with the space above the first partition and passing through each hole in the second partition spaced from the sides of said holes, means for supplying liquid to the space above the second partition, a third horizontal' partition spaced below said second partition and perforated, a bed of loosely packed solid material between the second and third partitions, said bed reaching up to the lower ends of said vertical pipes, and means for withdrawing liquid from the lower part of the container. I

In testimony whereof we have hereunto set our hands.
