Abstract

método e aparelho de tratamento do gás de escape. a presente invenção refere-se a um gás de escape descarregado a partir de um mecanismo para sitetização de minério de ferro em um processo de elaboração de ferro ou semelhante é submetido a um tratamento de remoção de pó e é posteriormente aquecido por meio de um queimador de aquecimento do gás de escape (5), qualquer óxido de nitrogênio no gás de escape é removido por uma ação catalítica, um calor do gás de escape depois da remoção do óxido de nitrogênio é recolhido e é reutilizado para o aquecimento para a remoção de óxido de nitrogênio do gás de escape através da atividade catalítica e, em seguida, qualquer óxido de enxofre ou semelhante é removido do gás de escape, do qual a temperatura foi diminuída, utilizando uma solução de absorção removida. desta forma, torna-se possível realizar a dessulfuração e desnitrificação em um gás de escape, mesmo quando o gás de escape é um descarregado a partir de outro aparelho além dos aparelhos de queima que utilizam carvão ou afins como um combustível.
