Abstract

processo de sinterização sinérgica de resíduos sólidos e disposição de pelotizantes. a presente invenção apresenta um processo sinérgico de sinterização e pelotização no descarte de resíduos sólidos. o processo de descarte compreende: peneirar resíduos sólidos obtidos por meio da submissão de resíduos sólidos de múltiplas fontes à incineração e/ou a um tratamento de pirólise, depois misturar e transportar resíduos sólidos de partículas grossas e matérias-primas de sinterização para um procedimento de sinterização, e misturar e transportar resíduos sólidos de partículas finas e matérias-primas de pelotização para um procedimento de pelotização. o resíduo sólido pode substituir parte do combustível, de modo que o custo de produção seja reduzido; além disso, ao adicionar seletivamente ao procedimento de sinterização ou ao procedimento de pelotização, também podem ser evitadas situações em que a qualidade da sinterização é reduzida devido à mistura direta de resíduos sólidos de partículas finas nas matérias-primas de sinterização e em que o resíduo sólido de partículas grossas que entra nas matérias-primas de pelotização não é benéfico para a pelotização. além disso, uma fonte de calor gerada durante o procedimento de incineração e/ou o procedimento de pirólise do resíduo sólido também pode entrar em um sistema de pré-tratamento de minério com alto teor de água como fonte de calor. visando oferecer uma nova maneira de realizar o descarte de vários resíduos sólidos durante todo o processo, o impacto dos resíduos sólidos no meio ambiente e o risco de poluição secundária são completamente eliminados, ao mesmo tempo, em que se garante a qualidade de um minério de sinterização e de um minério de pelotização.synergistic sintering process of solid waste and pellet disposal. The present invention presents a synergistic process of sintering and pelletizing for the disposal of solid waste. The disposal process comprises: sifting solid waste obtained by submitting solid waste from multiple sources to incineration and/or a pyrolysis treatment, then mixing and transporting coarse particle solid waste and sintering raw materials to a sintering, and mixing and transporting fine particle solid waste and pelletizing raw materials for a pelletizing procedure. solid waste can replace part of the fuel, so that the production cost is reduced; Furthermore, by selectively adding to the sintering procedure or pelletizing procedure, situations can also be avoided in which the sintering quality is reduced due to the direct mixing of fine particle solid waste into the sintering raw materials and in which the residue Coarse particle solid entering pelletizing raw materials is not beneficial to pelletizing. Furthermore, a heat source generated during the incineration procedure and/or the solid waste pyrolysis procedure may also enter an ore pretreatment system with a high water content as a heat source. aiming to offer a new way of disposing of various solid waste throughout the process, the impact of solid waste on the environment and the risk of secondary pollution are completely eliminated, at the same time, guaranteeing the quality of an ore. sintering and a pelletizing ore.
