Abstract
"MéTODO DE ALVEJAMENTO DE POLPA DE CELULOSE E LINHA DE ALVEJAMENTO PARA O MéTODO". A presente invenção se refere a um método de alvejamento de polpa de celulose em uma linha de alvejar possuindo pelo menos duas etapas de alvejamento (D~ 1~, D~ 2~) de tipo alcalino ou acídico, e a uma linha de alvejamento para o método, no qual a distribuição de filtrado é conduzida através da linha de alvejamento em contra-corrente para o fluxo de polpa de celulose estabelecido na linha de alvejamento. Ao invés de uma distribuição de filtrado convencional incluindo tanques de filtrado, um conduto principal de junção único (1) é utilizado para as etapas de alvejamento do mesmo tipo. Filtrado de lavagem obtido a partir das etapas de lavagem do mesmo tipo utilizado depois ou antes da etapa de alvejamento, é conduzido para um ponto de ramificação (A~ 1~, A~ 4~, A~ 6~) sobre o conduto principal (1), que está posicionado depois do ponto de ramificação para extração de líquido de lavagem e/ou de líquido de diluição para a etapa de lavagem em questão (A~ 1~, A~ 3~, A~ 5~, A~ 7~). Todos os pontos de ramificação no conduto principal de junção estão em comunicação aberta um com o outro no conduto principal, pelo menos como observado em uma direção a partir da última etapa de alvejamento. Por intermédio disso, um sistema de distribuição de filtrado simplificado e aperfeiçoado com uma operacionalidade aperfeiçoada é obtido. (Figura 2)
