Abstract

The scrap tyres are first coked in absence of air and the resultant coke is then burnt in air, leaving only the steel insert and the mineral fillers. Coking is pref. carried out in a bath of molten metal, e.g. Pb (alloys), and the coke is then burnt without smoke or dust in a grate, tunnel kiln or shaft furnace.

Description

Verfahren zur umweitunschädlichen Beseitigung von Autoreifen Die Erfindung bezieht sich auf ein Verfahren für die Beseitigung von Sondermüll, insbesondere von Autoreifen, ohne Gefahr für die Gesundheit, für das Wasser, die Luft und den Boden.Method for the environmentally safe disposal of car tires The invention refers to a procedure for the disposal of hazardous waste, in particular of car tires, without danger to health, to the water, the air and the Floor.

Beien bekannten Verfahren zur Beseitigung von unbrauchbaren Autoreifen und dergl. durch Verbrennung entsteht unter sehr großer - nicht regelbarer - Wärmeentwicklung eine erhebliche Umweltschädigung.With known methods for removing unusable car tires and the like. By combustion arises with a very large - not controllable - heat development significant environmental damage.

Zur Verhütung solcher schädlichen Verbrennungsfolgen. bei derartigen Abfallstoffen werden erfindungsgemäß diese zuerst unter Luftabschluß einer Verkokung bzw.Schwelung unterzogen, wobei Gase mit sehr hohem Heizwert frei werden. Nach dieser Entgasung wird der dabei entstehende "Eok.Rw verbrannt und als unschädlicher REckstand fallen z.B. bei Autoreifen nur Stahleinlagen und mineralische Füllstoffe an, die sich leicht trennen lassen.To prevent such harmful effects of burns. with such According to the invention, waste materials are first coked in the absence of air or exhaustion, which releases gases with a very high calorific value. After this After degassing, the resulting "Eok.Rw" is burned and treated as a harmless residue For example, car tires only contain steel inserts and mineral fillers that can be separated easily.

Das neuartige Verfahren ist anwendbar für Erzeugnisse aus vulkanisiertem Natur- oder Kunstkautschuk und ähnlichem Sondermüll,der nicht in herkömmlicher Weise unschädlich beseitigt werden kann.The novel process can be used for products made of vulcanized Natural or synthetic rubber and similar hazardous waste that is not collected in a conventional manner can be disposed of harmlessly.

Die benötigte Wärmemenge für dieses Verfahren kann durch die Verbrennung des anfallenden Gases und Kokses gedeckt werden.The amount of heat required for this process can be obtained from incineration of the resulting gas and coke are covered.

Zur Erreichung einer raschen und vollkommenen Verkokung von hutoreifen wird diese erfindungsgemäß vorwiegend in einem Metallbad durchgeführt, das gleichzeitig einen einfachen und gasdichten Abschluß der Vergasungskammer ermöglicht.To achieve rapid and complete coking of hat tires this is carried out according to the invention predominantly in a metal bath, which at the same time allows a simple and gas-tight closure of the gasification chamber.

jis Metallbad, in das z.B.Autoreifen unmittelbar eingebracht werden, wird erfindungsgemäß vorzugsweise Blei oder eine Bleilagierung verwendet.jis metal bath into which e.g. car tires are placed directly, lead or a lead coating is preferably used according to the invention.

Die Verbrennung des Rtickstandkokses kann nach der Erfindung rauch- und staubfrei auf einem Rost oder in einem Kanal- oder auch Schachtofen erfolgen.The combustion of the residual coke can be smoke-free according to the invention and dust-free on a grate or in a duct or shaft furnace.
