Abstract

Continuously extracting surface film of water involves using the water surface tension. Sound waves are used to create droplets when they leave the water, using the waters surface tension. The droplets are collected by absorption, using fine nets.

Description

Die Gewinnung des Oberflächenfilmes vom Wasser ist ein essenetieller Bestandteil wenn es um die Wechselwirkungen Wasser zur Gasphase geht. Denn in den oberen 50 – 100 Mikrometern des Wasser finden viele entscheidende Raktionen statt ( zB. Photochemie ).The extraction of the surface film Water is an essential ingredient when it comes to interactions Water goes to the gas phase. Because in the top 50 - 100 microns of water there are many decisive reactions (e.g. photochemistry).

Hier sind die Konzentrationen der Substanzen, die aus der Luft in das Wasser eingetragen werden, um den Faktor 10 – 100 höher, als in den etwas tieferen Wasserschichten ( ab 2 mm ). In den vergangenen 20 Jahren hat es eine Vielzahl von Versuchen gegeben, den microlayer-Film zu beproben ( siehe Anlage Seite 27 ).Here are the concentrations of the Substances that are introduced into the water from the air the factor 10 - 100 higher, than in the somewhat deeper water layers (from 2 mm). In the past There have been many attempts over 20 years, the microlayer film to be sampled (see attachment on page 27).

Dem im Patentanspruch 1 angegebenen Verfahren liegt das Problem zugrunde, dass die undefinierten Probenahme-Methoden wie zB.

  • a) Walzen rotieren im Wasser, mit einer Art Scheibenwischer wird das haftende Waser von der Oberfläche gestrichen.
  • b) feine Netze werden auf das Wasser gelegt, nach dem Abheben wird das haftende Wasser als Oberflächenfilm betrachtet
durch eine definierte Methode ersetzt werdenThe method specified in claim 1 is based on the problem that the undefined sampling methods such as.
  • a) Rollers rotate in the water, the adhesive water is wiped off the surface with a kind of windshield wiper.
  • b) fine nets are placed on the water, after lifting off the adhering water is considered as a surface film
be replaced by a defined method

Diese Probleme werden durch die im Patentanspruch 1 aufgeführten MerkmaleThese problems are caused by the im Claim 1 listed characteristics

Verfahren zur kontinuierlichen Gewinnung des Oberflächenfilm von Wasser in Form von aufspringenden Tropfen, ihr Inhalt an Substanzen wird an feinen Netzen durch Absorbtion gesammelt,
um den Oberflächenfilm zu erhalten, wird ein Lautsprecher an den Boden eines Metallgefäss angbracht. Die Schwingungen der Membrane übertragen sich auf das Wasser und die frei werdende Energie lässt Tropfen von der Oberfläche aufspringen, ihr Inhalt an Substanzen wird an feinen Netzen durch Absorbtion gesammelt. Die Oberflächenspannung ist hierzu der Schlüssel. Es wird eine quantitative Aussage möglich gelöst.Process for the continuous extraction of the surface film of water in the form of sprinkling drops, their content of substances is collected on fine meshes by absorption,
to obtain the surface film, a loudspeaker is attached to the bottom of a metal vessel. The vibrations of the membrane are transferred to the water and the energy released lets drops jump up from the surface, their content of substances is collected on fine meshes by absorption. The surface tension is the key. A quantitative statement is possible.

Die mit dem neuen Verfahren erziehlten Vorteile bestehen insbesonders darin:
mit der Messgrösse Oberflächenspannung gibt es eine klare Definition zur Probenahme. Abhängig von der Leistung ( Watt) und Wellenart (Sinus-, Rechteck-, Sägezahn-Verlauf) der Schallwellen läst sich die Ausbeute, in der Anzahl der Tropfen, steuern.The advantages achieved with the new process are in particular:
the surface tension measurement parameter provides a clear definition for sampling. Depending on the power (watts) and the type of wave (sine, rectangular, sawtooth) of the sound waves, the yield, in the number of drops, can be controlled.

Somit wird es möglich im Durchflusssystem kontinuierlich den Oberflächenfilm definiert zu sammeln. Da dies dann auch von einem fahrenden Schiff bei ruhiger See erlaubt ist kann erstmals ein quantitativer Vergleich vom Oberflächenfilm zur darüber stehenden Luft und den unteren Wasserschichten erfolgen.This makes it possible in the flow system continuously the surface film defined to collect. Since this is also from a moving ship Calm sea is allowed for the first time a quantitative comparison from the surface film to the one above Air and the lower water layers are made.
