Abstract

MéTODO E APARELHO DE SECAGEM DE MATéRIA-PRIMA úMIDA. A presente invenção refere-se a introdução de uma matéria-prima úmida, tal como carvão a ser carregado em um forno de coque, por meio da introdução de um gás de alta temperatura em uma secadora de camada fluidizada (4) como uma fonte de calor e de um gás fluidizante, a parte do gás de alta temperatura é soprada para dentro de um conduto de carregamento (6) para carregar a matéria-prima úmida na secadora de camada fluidizada (4). Conseqúentemente, é possível impedir que a matéria-prima úmida seja aderida ou depositada no conduto de carregamento da secadora de camada fluidizada em um baixo custo com uma estrutura simples.WET RAW MATERIAL DRYING METHOD AND APPARATUS. The present invention relates to the introduction of a wet raw material such as coal to be charged in a coke oven by introducing a high temperature gas into a fluidized layer dryer (4) as a source of heat and a fluidizing gas, the high temperature gas portion is blown into a loading duct (6) to load the wet raw material into the fluidized layer dryer (4). As a result, it is possible to prevent the wet raw material from being adhered to or deposited in the fluidized layer dryer loading duct at a low cost with a simple structure.
