Abstract
Description
Die Erfindung betrifft ein Verfahren und Einrichtungen zur Beseitigung halogenierter Aromaten oder Aliphaten emittierender Dicht- und Dehnungsfugenmassen.The invention relates to a method and devices for eliminating halogenated Aromatic or aliphatic emitting sealing and expansion joint compounds.
Dauerelastische Dehnungsfugenmassen sind häufig schadstoffbelastet, z. B. durch polychlorierte Biphenyle (PCB), polyzyklische aromatische Kohlenwasserstoffe (PAH), polychlorierte Dibenzodioxine und Furane (PCDD/PCDF) etc. Durch die aus den Dehnungsfugen austretenden Schadstoffe sind die benachbarten Bauteile bzw. die entsprechenden geschlossenen Bauanordnungen häufig mit den Schadstoffen an der Oberfläche gleichfalls kontaminiert. Eine entsprechende Kontamination kann bei der Herstellung der Bauteile oder Bauanordnungen auch über die Aufnahme von Schalöl oder dgl. auftreten.Permanently elastic expansion joint compounds are often contaminated, e.g. B. by polychlorinated biphenyls (PCB), polycyclic aromatic hydrocarbons (PAH), polychlorinated dibenzodioxins and furans (PCDD / PCDF) etc. through the The contaminants emerging from the expansion joints are the neighboring components or the corresponding closed building arrangements often with the pollutants the surface is also contaminated. Corresponding contamination can the manufacture of the components or building arrangements also via the inclusion of Formwork oil or the like occur.
Bauteile bzw. Bauanordnungen mit den zuvor erörterten Voraussetzungen müssen saniert werden. Dazu sind mechanische Räumverfahren bekannt (US-PS 3 110 054). Eine Weiterentwicklung demgegenüber ist schon vorgeschlagen worden EP 01 62 389 A2).Components or building arrangements with the previously discussed requirements must be refurbished. Mechanical clearing methods are known for this purpose (US Pat. No. 3,110,054). A further development, on the other hand, has already been proposed (EP 01 62 389 A2).
Das bekannte Verfahren nutzt zum Entfernen der Dehnungsfugenmasse zwei an beiden Seiten in der Dehnungsfuge geführte Schneidmesser. Dadurch wird der Streifen der Dehnungsfuge herausgetrennt. Dieses Verfahren hat zunächst keine vollständige Entfernung der Dehnungsfugenmasse zur Folge, da die Vernetzung der Dehnungsfugenmasse mit den angrenzenden Kontaktflächen der Bauteile wegen der Dauerelastizität und der normalerweise gewählten Einbringungsart sehr eng ist. Deshalb wird hier eine Nachbearbeitung der Dehnungsfuge derart vorgenommen, daß die anhaftenden Rückstände der Dehnungsfugenmasse mittels eines Stickstoffstrahls versprödet und durch drehende Stahlbürsten entfernt werden.The known method uses two to remove the expansion joint compound Cutting knives guided on both sides in the expansion joint. This will make the Strips of the expansion joint cut out. Initially, this procedure has none complete removal of the expansion joint compound as a result of the crosslinking of the Expansion joint compound with the adjacent contact surfaces of the components because of the Permanent elasticity and the type of application normally chosen is very narrow. Therefore, the expansion joint is reworked in such a way that the adhering residues of the expansion joint compound by means of a nitrogen jet embrittled and removed by rotating steel brushes.
Weiterhin ist in Patentschrift DE 40 28 434 C2 ein Vereisungsverfahren zur Entfernung von Dehnungsfugen beschrieben, das unmittelbar vor dem mechanischen Entfernen eines bestimmten Abschnitts der Dehnungsfugenmasse diese auf eine erheblich unter 273 K liegende Temperatur schockartig abkühlt und so erhärtet und versprödet, daß ein mechanisches Entfernen durch Herausschlagen erfolgen kann.Furthermore, patent specification DE 40 28 434 C2 describes an icing process for removal described by expansion joints immediately before mechanical removal of a certain section of the expansion joint compound this significantly temperature below 273 K cools suddenly and thus hardens and embrittled that mechanical removal can take place by knocking out.
Der angemeldeten Erfindung liegt die Aufgabe zugrunde, ein staubfreies und schadstoffemissionsfreies Verfahren zu entwickeln, das ohne den oben genannten mechanischen Aufwand auskommt und dennoch kostengünstig und frei von Schadstoffbildung arbeitet. Außerdem soll eine vollständige Entfernung der Fugenmasse gewährleistet sein und keine Nachbehandlung nötig sein.The registered invention is based on the object, a dust-free and pollutant-free Process to develop that without the mechanical above Effort comes out and yet inexpensive and free of pollutants is working. In addition, a complete removal of the grout should be guaranteed be and no after-treatment is necessary.
Diese Aufgabe wird gemäß Anspruch 1 gelöst.This object is achieved according to claim 1.
Durch das Verfahren gemäß Anspruch 1 werden die Fugenmassen und die beinhalteten Schadstoffe thermisch zerstört. Dabei wird die Bildung der hochgiftigen Schadstoffe (polychlorierte Dibenzodioxine und Furane (PCDD/PCDF etc.) bei der Verwendung einer Langmuirfackel durch die Anwesenheit von atomarem Wasserstoff und bei Verwendung eines Brenners durch die reduzierte Atmosphäre verhindert. Die bei dem Prozeß entstehenden Gase, die Abbauprodukte der Dehnungsmasse und der enthaltenen Schadstoffe enthalten, werden mit Hilfe einer Absaugvorrichtung entsprechend Anspruch 5 entfernt. Vorteilhaft ist die Verwendung einer Langmuirfackel nach Anspruch 3, da hier die höchsten Temperaturen, die selbst vorhandenes Restdioxin thermisch spalten, erreicht werden. Auch werden durch die reduktive Kraft des atomaren Wasserstoffs die polychlorierten Biphenyle sehr leicht dehalogeniert bzw. zerstört und die Bildung von Dioxin ausgeschlossen. Bei Verwendung einer reduzierenden Flamme nach Anspruch 4 können die oben genannten Bedingungen unter günstigen Umständen ebenfalls erreicht werden.By the method according to claim 1, the grout and the included Thermally destroyed pollutants. This causes the formation of highly toxic pollutants (polychlorinated dibenzodioxins and furans (PCDD / PCDF etc.) when using a Langmuir torch due to the presence of atomic hydrogen and prevented by the reduced atmosphere when using a burner. The gases generated in the process, the degradation products of the expansion compound and of the contained pollutants are removed with the help of a suction device removed according to claim 5. The use of a Langmuir torch is advantageous according to claim 3, since here the highest temperatures, the existing ones Thermally split residual dioxin can be achieved. Also through the reductive Due to the atomic hydrogen, the polychlorinated biphenyls are very easily dehalogenated or destroyed and the formation of dioxin excluded. Using a reducing flame according to claim 4 can meet the above conditions can also be achieved under favorable circumstances.
