Способ рециркуляции отходов минеральных волокон, имеющих органическое покрытие из связующего вещества, осуществляется в стекловаренной печи с высокой степенью перемешивания, в которой органическое связующее покрытие разрушается под воздействием тепла. Углерод из органического связующего покрытия окисляется на поверхности расплавленного стекла. После окисления углерода стекловолокна диспергируются в расплаве. Остаточный углерод может окисляться после включения в расплав. Очищенное стекло, пригодное для формирования стеклянных волокон, подвергается дальнейшей обработке на обычном оборудовании для формирования стеклянных волокон. Способ может также включать операцию предварительной обработки отходов стекловолокон путем их измельчения или превращения в порошок для облегчения подачи отходов в стекловаренную печь с высокой степенью перемешивания. Установка для осуществления способа представляет собой стекловаренную печь, имеющую электрический нагрев джоулевым теплом. Крыльчатка стекловаренной печи перемешивает расплав с высокой скоростью, чтобы создать всасывающий эффект, обеспечивающий втягивание волокон в расплав.The method of recycling waste mineral fibers with an organic coating of a binder, is carried out in a glass melting furnace with a high degree of mixing, in which the organic binder coating is destroyed by heat. The carbon from the organic binder coating is oxidized on the surface of the molten glass. After carbon is oxidized, glass fibers disperse in the melt. Residual carbon can be oxidized after incorporation into the melt. Purified glass suitable for forming glass fibers is further processed using conventional glass fiber forming equipment. The method may also include the operation of pre-treatment of waste glass fibers by grinding them or turning into powder to facilitate the supply of waste in a glass furnace with a high degree of mixing. Installation for implementing the method is a glass furnace with electric heating Joule heat. The impeller of the glass melting furnace mixes the melt at high speed in order to create a suction effect that draws the fibers into the melt.
