Description

Böden wurden oftmals durch darauf stehende und betriebene Fabrikanlagen durch ausgelaufene und eingesickerte Öle ver­ seucht. Sie müssen oft bis zu beachtlichen Tiefen ausgehoben und auf Sondermülldeponien gebracht werden, was sehr kost­ spielig ist. Auch bei Ölunfällen wird Erdreich oft verseucht und muß gereinigt werden. Eine andere Methode besteht in der Erhitzung auf ca. 700°C in Drehrohröfen. Eine weitere Metho­ de besteht darin, solche Böden, Lehme etc. mit Hochdruckwas­ ser zu reinigen, was aber nur bei Sanden und ähnlichen Granu­ laten vollständig gelingen dürfte.Soils were often created and operated on Factory plants by leaking and infiltrated oils ver plagues. They often have to be excavated to considerable depths and brought to hazardous waste sites, which is very expensive is playful. Soil is also often contaminated in oil spills and must be cleaned. Another method is Heating to approx. 700 ° C in rotary kilns. Another metho de consists of such floors, loams etc. with high pressure water to clean, but only with sand and similar granu laten should succeed completely.

Aufgabe der Erfindung ist es, solche Böden nicht nur zu be­ handeln, sondern daraus ein verwertbares Wirtschaftsgut herzustellen und zwar unter besseren Reinigungsbedingungen der Böden selbst und unter Einhaltung lufthygienischer Er­ fordernisse.The object of the invention is not only to be such floors act, but a usable economic asset to manufacture and under better cleaning conditions of the floors themselves and in compliance with air hygiene standards requirements.

Erfindungsgemäß wird vorgeschlagen, zur Entsorgung von mit Ölen oder sonstigen Kohlenwasserstoffen verseuchte Böden, Tone, Lehme oder ähnliches Bodenmaterial zu Formlingen zu formen, zu Trocknen und zu brennen.According to the invention it is proposed to dispose of with Soils contaminated with oils or other hydrocarbons,  Clays, loams or similar soil material to form shape, dry and burn.

Dabei ist das Brennen in einem Durchlaufofen mit integrier­ ter thermischer Abgasverbrennung durchzuführen, z. B. nach DBP 26 43 406, so daß die Pyrolysegase aus der Anwärmzone in der Hochtemperaturzone restlos verbrannt werden können.The firing is integrated in a continuous furnace ter thermal flue gas combustion to perform, for. B. after DBP 26 43 406 so that the pyrolysis gases from the heating zone can be completely burned in the high temperature zone.

Im Falle die verseuchte Erde zum Verformen z. B. auf Strang, pressen nicht bildsam genug ist, wird ein Bindeton zugemischt, um die dazu erforderliche Bildsamkeit herzustellen.In the case of contaminated earth to deform z. B. on strand, pressing is not sufficiently plastic, a binding clay is mixed in, to create the necessary plasticity.

Im Falle ein solches Materialgemenge genügende Eigenschaften aufweist, so werden daraus Mauerziegel hergestellt. Falls die Qualität nicht ausreicht, so werden die gebrannten Form­ linge gebrochen oder vermahlen zu Schotter, Split oder Ton­ mehl weiterverarbeitet.In the case of such a material mixture, sufficient properties bricks are made from them. If the quality is not sufficient, so the fired shape linge broken or ground to crushed stone, split or clay flour processed.

Solche Materialien eignen sich besonders für Wege und Sport­ anlagenbau oder als Filtermaterial.Such materials are particularly suitable for trails and sports plant construction or as filter material.
