Description

Verfahren zur elektrischen Abscheidung von Körnchen und Tröpfchen aus Gasen mittels Röntgenstrahlen. Bekanntlich bringen Röntgenstrahlen bei ihrer Absorption in Körpern negative Elektronen zur Emission, so daß insonderheit die bestrahlten festen oder flüssigen Körper, wenn sie isoliert sind, unter- der Einwirkung der Röntgenstrahlen eine positive Ladung annehmen. Je stärker die Absorption ist, desto stärker ist die Emission negativer Elektronen und damit die positive Aufladung. Wirken daher Röntgenstrahlen auf Gase ein, in denen sich Schwebekörper befinden, so müssen diese gegebenenfalls beim Durchgang des Gases durch ein entsprechend starkes elektrisches Feld aus dem Gas niedergeschlagen werden können.Process for the electrodeposition of granules and droplets from gases by means of X-rays. It is well known that X-rays bring in her Absorption in bodies negative electrons for emission, so that in particular the irradiated solid or liquid bodies, if they are isolated, under the influence of the X-rays take on a positive charge. The stronger the absorption, the stronger the emission of negative electrons and thus the positive charge. Therefore, if X-rays act on gases containing floats, so this must be necessary when the gas passes through a correspondingly strong electric field can be deposited from the gas.

Diese Tatsache wird nach der Erfindung zur Trennung verschiedener, in gewissen Hochofengasen gemischter Schwebekörper ausgenutzt. Die Absorption von Röntgenstrahlen in chemischen Atomen von verschiedenen Gewichten ist nämlich je nach der Wellenlänge der Röntgenstrahlen verschieden groß, und da letztere in chemischen Elementen von großem Atomgewicht stärker absorbiert werden als in solchen von geringerem Atomgewicht, so können mit dem Verfahren aus einem Gemisch von chemisch verschiedenen Körnchen oder Tröpfchen, die in einem Gase schweben, diejenigen Tröpfchen und Körnchen abgeschieden werden, die ein hohes Atomgewicht, wie z. B. Silber, Blei, Gold, Platin, besitzen, während die übrigen Schwebekörper im Gas verbleiben. Aüf diese Weise kann man beispielsweise Gold aus den Abgasen bei der Verhüttung von arsen-und kupferhaltigen Erzen gewinnen, das von dem Arsen mit fortgenbmmen wird.This fact is used according to the invention for the separation of different, Float mixed in certain blast furnace gases is used. The absorption of X-rays in chemical atoms of different weights is namely each different in size according to the wavelength of the X-rays, and there the latter in chemical Elements of high atomic weight are absorbed more strongly than those of lesser ones Atomic weight, so can with the process of a mixture of chemically different Granules or droplets suspended in a gas, those droplets and granules are deposited that have a high atomic weight, such as. B. silver, lead, gold, platinum, own, while the remaining floats remain in the gas. In this way you can For example, you can get gold from the exhaust gases in the smelting of arsenic and copper Extract ores that are carried away by the arsenic.

Macht man die Intensität der Röntgenstrahlen gerade für die Röntgen-Eigenfrequenzen eines bestimmten chemischen Elementes vorzugsweise groß, dann lassen sich allgemein aus dem Gemisch vorzugsweise oder selektiv die das bestimmte chemische Element in erheblicher Konzentration enthaltenden Körnchen oder Tröpfchen mit Hilfe des vorstehenden Verfahrens abscheiden.Make the intensity of the x-rays just for the x-ray natural frequencies of a certain chemical element preferably large, then can be general from the mixture, preferably or selectively, the particular chemical element in granules or droplets containing substantial concentration by means of the above Process.

PATENTANSPRUCH: Verfahren zur elektrischen Abscheidung von Schwebekörpern aus Gasen mittels Röntgenstrahlen und eines elektrischen Feldes, dadurch gekennzeichnet, daß die Gase behufs Abscheidung von bestimmten Schwebekörpern mit Röntgenstrahlen solcher Intensität behandelt werden, daß sie für die Röntgen-Eigenfrequenz des abzuscheidenden Stoffes vorzugsweise groß ist, so daß die Röntgenstrahlen gerade von den aus diesem Stoffe bestehenden Schwebeteilchen absorbiert, diese dadurch vorzugsweise positiv aufgeladen und infolgedessen durch ein elketrisches Feld abgeschieden werden. Claim: method for the electrical separation of floating bodies from gases by means of X-rays and an electric field, characterized in that the gases are treated for the separation of certain floating bodies with X-rays of such intensity that it is preferably large for the natural X-ray frequency of the substance to be deposited, so that the X-rays are absorbed by the suspended particles consisting of this substance, which are thereby preferably positively charged and consequently separated by an electrical field.
