Abstract

MéTODO E DISPOSITIVO PARA LAVAGEM DE LAMA DE CAL. A presente invenção refere-se a um método e a uma disposição para desidratação e lavagem de uma pasta fluida de cal (106), antes da lama de cal desidratada ser passada para um forno de lama de cal (200). A invenção se fundamenta na desidratação da pasta fluida de cal em um filtro pressurizado de lama de cal (102), do tipo disco ou tambor. O filtro pressurizado de lama de cal (102) é pressurizado através de um compressor (111), que arrasta na(s) sua(s) parte(s) de sucção a fase gasosa proveniente do tanque de filtrado (108) e pressuriza na parte pressurizada (p) do compressor o vaso de pressão (105), na superfície da lama de cal do filtro. Uma certa quantidade predeterminada de fase gasosa no sistema de circulação de gás é liberada e uma quantidade predeterminada equivalente de ar fresco é adicionada à fase gasosa reciclada, com o objetivo de manter a pressão parcial do oxigênio gasoso acima de um nível mínimo predeterminado.
