Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Behandlung eines Fluids, einer wässrigen Lösung oder Flüssigkeit oder dgl., in einem Reaktionsraum, insbesondere zur Verringerung des Anteils an unerwünschten Bestandteilen, (vor allem Toxine).The The invention relates to a method for treating a fluid, an aqueous solution or liquid or the like., In a reaction space, in particular for reduction the proportion of unwanted Ingredients, (especially toxins).
Unter derartigen Bestandteilen werden neben Toxinen auch Keime, Sporen, Herbizide, Fungizide, Pestizide, Restdüngemittel, Restmedikamente undgl. verstanden.Under such constituents, in addition to toxins, also germs, spores, Herbicides, fungicides, pesticides, residual fertilizers, residual medicines and the like. Understood.
Es ist bekannt Ultraschall einzusetzen, um Flüssigkeiten zu desinfizieren. Wenngleich hier Einflüsse z. B. auf Endotoxine zu erwarten sind, so hat sich doch in Versuchen gezeigt, dass sich mit Hilfe des Ultraschalls in biologischen Flüssigkeiten der Anteil an Endotoxinen nicht zufrieden stellend herabsetzen lässt, schon gar nicht so weit, dass von Endotoxinfreiheit gesprochen werden könnte, d. h. unter 0,4 EU/ml an Endotoxinen in der Flüssigkeit verbleiben.It It is known to use ultrasound to disinfect liquids. Although here influences z. B. are expected to endotoxins, it has yet in trials shown using ultrasound in biological fluids the proportion of endotoxins can not be reduced satisfactorily, not so far as to speak of endotoxin freedom could, d. H. remain below 0.4 EU / ml of endotoxins in the fluid.
Es ist auch bekannt, Wasserstoffperoxid zur Entkeimung von Flüssigkeiten einzusetzen, wenngleich dessen Reaktion mit organischen Substraten träge abläuft. Eine Einwirkung auf Toxine z. B. wäre nur dann möglich, wenn mit relativ hohen Konzentrationen vorgegangen wird. Dies führt dann zwangsläufig dazu, dass in der behandelten Flüssigkeit Rest-Wasserstoffperoxid verbleibt, was abhängig vom Einsatzzweck der Flüssigkeit andere nicht tragbare Risiken mit sich bringt.It is also known, hydrogen peroxide for the sterilization of liquids although its reaction with organic substrates is sluggish. A Exposure to toxins z. B. would only be then possible when proceeding with relatively high concentrations. This then leads inevitably to that in the treated liquid residual hydrogen peroxide remains what depends on Purpose of the liquid other non-viable risks.
Es ist auch bekannt, Keime in Flüssigkeiten mit Hilfe von UV-Strahlung zu inaktivieren, eine Verringerung des Anteils an Toxinen hat sich nicht gezeigt.It is also known to carry germs in liquids Help inactivate UV radiation, reducing the proportion toxins have not been shown.
Die vorliegende Erfindung ist nicht auf die Behandlung von Flüssigkeiten hinsichtlich der Toxin- oder Endotoxinfreiheit begrenzt, sondern soll allgemein einsetzbar sein, wenn es darum geht, die eingangs genannten Bestandteile neben anderen Fremdstoffen aus Fluiden oder wasserhaltigen Flüssigkeiten oder Lösungen zu entfernen.The The present invention is not for the treatment of liquids limited in toxin or Endotoxinfreiheit, but should be universally applicable when it comes to the beginning mentioned constituents in addition to other foreign substances from fluids or hydrous liquids or solutions to remove.
Für die vorliegende Erfindung ist der Einsatz von vier Verfahrens-Merkmalen wesentlich, bedeutsam ist jedoch auch die sich aus der Verwendung dieser Merkmale ergebenden Wechselwirkungen, die bislang in diesem Zusammenhang nicht eingesetzt oder beschrieben worden sind.For the present Invention, the use of four process features is essential However, it is also significant that the use of these features resulting interactions, so far in this context have not been used or described.
Das erste wesentliche Merkmal der vorliegenden Erfindung ist die Erzeugung eines Radikalbildners in einem separaten Reaktionsraum, abgetrennt vom eigentlichen Reaktionsraum, jedoch mit diesem über eine Zuleitung verbunden. In diesem separatem Reaktionsraum kann ein H2O2-Aerosol und/oder ein Peressigsäure-Aerosol mit Hilfe eines Schallgenerators mit einer Frequenz von ca. 1,6 MHz gebildet werden.The first essential feature of the present invention is the generation of a radical generator in a separate reaction space, separated from the actual reaction space, but connected to this via a feed line. In this separate reaction space, an H 2 O 2 aerosol and / or a peracetic acid aerosol with the aid of a sound generator with a frequency of about 1.6 MHz can be formed.
Die so erzeugten Radikalbildner gelangen in den Reaktionsraum und werden dort mit Hilfe eines UV-Strahlers zu einem Aerosol umgewandelt, das nun wiederum auf die zu behandelnde Flüssigkeit einwirken kann. Die zu behandelnde Flüssigkeit wird im Reaktionsraum den Schwingungen eines Schallgenerators bei ca. 40 kHz ausgesetzt, so dass die Flüssigkeit fein zerstäubt vorliegt und eine sehr effiziente Wirkung der relativ großen Aerosol- Tröpfchen des Radikalsbildners auf diese zerstäubten Flüssigkeit eintreten kann.The Radicals generated in this way enter the reaction space and become converted there to an aerosol with the help of a UV lamp, which in turn can act on the liquid to be treated. The liquid to be treated becomes in the reaction space the vibrations of a sound generator 40 kHz exposed so that the liquid is finely atomized and a very efficient effect of the relatively large aerosol droplets of the Radicalizer on this atomized liquid can occur.
Die sich hieraus ergebene Wirkung ist, dass die Bestandteile sowie sie eingangs erwähnt worden sind, aufgespalten werden, insbesondere werden Toxine in unwirksame Toxinreste aufgespalten. Dies bedeutet mit anderen Worten, dass die Flüssigkeit hochgradig von Fremdbestandteilen befreit werden kann, jedenfalls von Bestandteilen, die in irgendeiner Weise noch eine Wirkung ausüben können. Es kann also eine sehr effektive Sterilisation und Elimination von organischen Substanzen erreicht werden.The The resulting effect is that the ingredients as well as them mentioned in the beginning In particular, toxins will be in inactive toxin residues split. In other words, this means that the fluid is high grade may be exempted from foreign components, in any case from constituents, which in some way can still have an effect. So it can be a lot effective sterilization and elimination of organic substances be achieved.
Bei diesem Vorgang können auch Wasserperoxid und Peressigsäure entstehen. Da aber ein UV-Strahler in dem Reaktionsraum vorhanden ist, kann er sowohl das Wasserstoffperoxid als auch die Peressigsäure umwandeln in Radikalbildner, die nun wiederum auf die zu behandelnde Flüssigkeit einwirken können. Es liegt auf der Hand, dass hierdurch eine beachtliche Effizienzsteigerung erzielt werden kann.at this process can also water peroxide and peracetic acid arise. But since there is a UV lamp in the reaction space is, he can convert both the hydrogen peroxide and the peracetic acid in radical formers, which now turn on the liquid to be treated can act. It is obvious that this results in a considerable increase in efficiency can be achieved.
