Title:
METHOD AND DEVICE FOR RECYCLING AND REUSING A ROOFING BITUMINOUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2005/087380
Kind Code:
A1
Abstract:
The invention relates to material recycling, in particular to recycling and reusing roofing bituminous wastes. The inventive method consists in grinding wastes and in loading said wastes in a tank for melting bitumen and removing a paperboard base therefrom in the presence of a liquid contact heat carrier. During heating, a combustion gas is removed under a pressure from the furnace of the tank through a duct in order to reduce the combustion gas pressure and through a pipeline to a gas separator for retaining and deposing carbon. Afterwards, the gas is led to a filtering unit and exhausted to the atmosphere in the form of a pure air. The molten bitumen and a paperboard paste are removed from the melting tank and cooled to a temperature equal to or less than 140 °C. The paperboard paste is washed in a bitumen-solving reagent and is used for producing roofing materials and/or as a burning material. A liquid phase remaining after washing is used in the form of a base for producing bituminous paints, the carbon is used at least for producing mechanical rubber goods or as a dyestuff or as a pigment for a paint and varnish production. The device for carrying out said method and the elements thereof such as a gas separator, a gas filtering unit and a bitumen-melting boiler are also disclosed. Said invention makes it possible to optimise a process for a nonwaste and ecologically clean recycling of the roofing bituminous wastes, to increase the low-energy and low material consuming high performance production, reduce the reprocessing time, simplifies the method and reduce the material consumption of the device.
