Abstract
"MéTODO E DISPOSITIVO PARA A MANIPULAçãO DE POLPA DE CELULOSE". A presente invenção diz respeito a um método e a um dispositivo para a diluição de polpa de celulose desaguada os quais mantêm a polpa de celulose com uma consistência de 30 % ou maior. Em concordância com a presente invenção, o referido método e o referido dispositivo estão caracterizados pelo fato de que: - a esteira é finamente dividida pelo desfibramento do parafuso desfibrador (8) de maneira tal que a polpa de celulose é granulada para um tamanho que está normalmente distribuído em torno de uma dimensão na faixa de 5 mm - 40 mm; - a polpa de celulose granulada a partir da saída do parafuso desfibrador (8) é alimentada para cair livremente em uma tubulação de subida (22, 40<39>) conectada para a extremidade de saída da cobertura exterior (23) do parafuso desfibrador (8); - e de que o fluido de diluição (Liq~ DIL~) é adicionado sob pressão para a tubulação de subida (22, 40<39>) através de um número de bocais (62) dispostos em torno da periferia da tubulação de subida (22, 40<39> e acima de um nível (Liq~ LEV~) de polpa de celulose diluída estabelecido na tubulação de subida (22, 40<39>); - onde a quantidade de fluído de diluição adicionado (Liq~ DIL~) estabelece uma consistência da polpa de celulose na faixa de consistência de meio de 8 % - 16 % e de que esta quantidade adicionada, para mais do que 50 %, preferivelmente para mais do que 75 % - 90 %, é adicionada através dos referidos bocais (62) dispostos acima de um nível (Liq~ LEV~) de polpa de celulose estabelecido na tubulação de subida (22, 40<39>); - depois do que a polpa de celulose nesta consistência de meio é alimentada para frente para subseq³entes etapas de tratamento para a polpa de celulose por uma bomba (41) conectada para tubulação de subida (22, 40<39>) na sua extremidade inferior próxima para o fundo da tubulação de subida (22, 40<39>); - e onde a diluição na tubulação de subida (22, 40<39>) da polpa de celulose a partir de uma alta consistência de 30 % ou maior na parte superior da tubulação de subida (22, 40<39>) para uma consistência de meio de 8 % - 16 % antes que bombeamento na parte inferior da tubulação de subida (22, 40<39>) venha a acontecer exclusivamente sob a influência de efeitos hidrodinâmicos a partir da adição do fluido de diluição (Liq~ DIL~) através dos referidos jatos de fluido (62) e onde não estão dispostos agitadores mecânicos entre a saída do granulado seco a partir do parafuso desfibrador (8) e o subseq³ente bombeamento.
