Abstract

Patente de Invenção: " TROCADOR DE CALOR DE LEITO DE CHUVA E MéTODO DE UTILIZAçãO". Um trocador de calor de leito em queda que inclui: uma coluna oca; uma entrada de alimentação localizada próxima ao topo da coluna para introduzir o material particulado na coluna de modo que o material caia através da coluna; uma entrada de gás localizada próxima ao fundo da coluna para introduzir gases ascendentes na coluna de modo que os gases fluam em sentido contrário ao material em queda; uma pluralidade de defletores suportados dentro da coluna entre as entradas de alimentação e de gás para retardar o material em queda e prolongar sua exposição aos gases; e uma seção de desengate localizada próxima ao topo da coluna para separar dos particulados de gases introduzidos pelos gases em elevação. A seção de desengate inclui uma tela posicionada dentro da coluna e possui um pluralidade de aberturas através das quais os gases ascendentes passam a fim de separar suficientemente os particulados introduzidos. Alternativamente, a seção de desengate pode incluir meio de filtro para separar os particulados introduzidos. Também, pelo menos um dos defletores pode incluir um tubo oco e isolamento refratário circundando o tubo oco. O trocador de calor pode ser conectado a um ciclone para formar um sistema trocador de calor que inclui um mecanismo de geração de fluxo adaptado para reintroduzir continuamente os particulados separados pelo ciclone de volta ao trocador de calor. A invenção caracteriza também um método de usar um trocador de calor de leito em queda para preaquecer eficientemente e calcinar parcialmente o calcário antes de distribuir o calcário a um forno de calcinação.
