Abstract
Description
Es ist bekannt, Altlasten-Sanierungen durchzuführen, d. h. kontaminierte Böden auszugraben, thermisch zu behandeln oder waschtechnisch zu reinigen und mit Bodenbakterien zu versehen, um den Boden dann wieder als Wachstumsboden zu verwenden.It is known to remediate contaminated sites, d. H. Dig up contaminated soils thermally treat or wash and clean with To provide soil bacteria to the soil again to use as growth soil.
Es gibt verschiedene Methoden der thermischen Boden reinigung, wobei grundsätzlich bei den bekannten Ver fahren der Boden ausgebaggert und einer thermischen Behandlung in einer Vorrichtung dafür zugeführt wird.There are different methods of thermal soil cleaning, basically with the known Ver drive the ground dredged and a thermal Treatment is supplied in a device for this.
Weiterhin ist bekannt, Böden durch Sickerbrunnen und Schöpfbrunnen zu reinigen.It is also known soils through seepage wells To clean the well.
Die nachstehende Erfindung hat zur Aufgabe, bestimmte verunreinigte Böden an Ort und Stelle thermisch zu be handeln in der Form, z. B. fetthaltige Böden wie ölge tränkte Böden bzw. Böden, die mit leichten bis mittleren Kohlenwasserstoffen durch Straßenunglücksfälle z. B. ver seucht sind, preiswert zu reinigen.The following invention aims to determine certain to contaminate soils on the spot act in the form, e.g. B. fatty soils such as oil soaked floors or floors with light to medium Hydrocarbons from road accidents such. B. ver are addicted to clean inexpensively.
Erfindungsgemäß wird daher vorgeschlagen, in den Boden Injektionslanzen einzudrücken oder bohr technisch näher zu bringen, um aus dem Injektions lochtiefsten brennbare neutrale Stoffe ausfließen zu lassen, - die Gasbrennlanzen -, die z. B. gleich zeitig mit einem Luftüberschuß aus dem Injektions lochtiefsten eine regelrechte Hochtemperatur im Bereich des Austritts erzeugen und das Erdreich derart erhitzen, daß eine weitere Zündung und Anbrennen der Stoffe, die brennfähig sind, wie Altöle und dergleichen, erfolgt, um somit an Ort und Stelle, ohne den Boden ausbaggern zu müssen, ein Abbrennen der Bodenbelastung zu erzielen. Damit die Abgase nicht die Umwelt belasten, wird eine deckelförmige Bewehrung vorgesehen, und diese wird mit bekannten trockenen oder nassen Gas reinigungsverfahren gekuppelt, so daß die Rück standsprodukte aus dem Boden verbrannt werden und die Abluft aus dieser Verbrennung der gereinigten Atmosphäre übergeben wird.According to the invention it is therefore proposed in the Pushing in or lancing soil injection lances to bring technically closer to out of the injection Outflows of flammable neutral substances to let - the gas firing lances - the z. B. the same early with an excess of air from the injection deep down a veritable high temperature in the Generate area of exit and soil heat so that another ignition and Burning the substances that are flammable, such as Waste oils and the like, is done in order to be in place and place without having to dredge the ground to burn off the floor load. So that the exhaust gases do not pollute the environment a lid-shaped reinforcement is provided, and this comes with known dry or wet gas cleaning process coupled so that the return stand products are burned from the ground and the exhaust air from this combustion of the cleaned Atmosphere is passed.
Selbstverständlich ist die Erfindung nicht auf die im einzelnen beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, kontaminierte Böden, die mit leichten bis mittel schweren Kohlenwasserstoffen belastet sind, injektionstechnisch aus dem notwendigen tiefsten Injektionsloch mit Luftüberschuß und brennbaren Stoffen wie Gas zu versehen, so daß eine Hoch temperaturzone zwangsläufig im Erdreich geschaffen wird, die zur Zündung und sukzessiven Verbrennung bis zur Oberfläche des kontaminierten Bodens führt.Of course, the invention is not limited to that limited form of training described in detail, there are numerous changes possible without deviating from the basic idea, contaminated soils with light to medium heavy hydrocarbons, injection technology from the deepest necessary Injection hole with excess air and flammable To provide substances like gas, so that a high temperature zone inevitably created in the ground which is used for ignition and gradual combustion leads to the surface of the contaminated soil.
