Abstract
SISTEMA PARA RECEPÇÃO E TRANSPORTE DE LAMA DE CAL DE UM FILTRO DE LICOR BRANCO A invenção se refere a um sistema para a recepção e transporte de lama de cal seca de um filtro pressurizado que opera continuamente 1 em um processo de caustificação. De acordo com a invenção, uma válvula de tubo 14 é usada como meios de saída do processo pressurizado. A válvula de tubo tem um comprimento mínimo que é duas vezes o diâmetro do tubo, e uma coluna de lama de cal pode ser segurada dentro disso como uma trava de pressão, e a coluna de lama de cal pode ser descendida através da válvula de tubo por controle da diferença em pressão entre a superfície interna e a superfície externa do tubo tal que o diâmetro do tubo se expande essencialmente uniformemente ao longo do seu comprimento por 5-10% ou por pelo menos 4-6 mm.
