INDUSTRIAL PROCESS FOR THE DIRECT TEMPERATURE INDUCED TRANSFORMATION AND RECYCLING OF ASBESTOS CONTAINING WASTES USING A TUNNEL KILN |
摘要 |
An industrial process for the temperature induced, complete transformation of packages of plastic material containing roofing cement-asbestos slates or other asbestos containing wastes such as friable asbestos. The industrial firing process ensures a complete transformation of both the package and the asbestos containing material via a decomposition reaction of the organic compounds and a decomposition and recrystallization of all the inorganic mineral phases including the asbestos minerals.
To this aim, the steps of the firing cycle which are required are:
Step 1: a heating non-isothermal run up to the maximum firing temperature of 1200- 1300 °C not shorter than 8 h;
Step 2: an isotherm at the maximum firing temperature of 1200-1300 °C not shorter than 12 h;
Step 3: a slow cooling non-isothermal run down to room temperature not shorter than 6 h. |
