Abstract

"MéTODO E DISPOSIçãO PARA TRATAR POLPA". A presente invenção refere-se a um método e a uma disposição para tratar polpa. O método e a disposição de acordo com a invenção são apropriados para uso na produção de polpa química em situações nas quais gás precisa ser separado da polpa e a polpa precisa ser diluída. Um aspecto caracterizador do método e da disposição para tratar polpa de acordo com a invenção, método no qual a polpa é transferida de um primeiro aparelho de tratamento de polpa (5), que trata a polpa em uma consistência mais alta, para um segundo aparelho de tratamento de polpa (50), que trata a polpa em uma consistência mais baixa, é que gás é separado da polpa em uma consistência mais alta do que a referida segunda consistência, a polpa é bombeada por meio de uma bomba (26) para um segundo tratamento realizado em consistência baixa, sendo que a polpa é diluída com um aparelho (28) localizado depois da bomba (26) para a referida segunda consistência, antes do tratamento na referida consistência."METHOD AND PROVISION FOR TREATING PULP". The present invention relates to a method and arrangement for treating pulp. The method and arrangement according to the invention are suitable for use in the production of chemical pulp in situations where gas needs to be separated from the pulp and the pulp needs to be diluted. A characteristic feature of the method and arrangement for treating pulp according to the invention is the method in which the pulp is transferred from a first pulp treatment apparatus (5) which treats the pulp at a higher consistency to a second apparatus. pulp treatment (50), which treats the pulp at a lower consistency, is that gas is separated from the pulp at a higher consistency than said second consistency, the pulp is pumped by means of a pump (26) to a second treatment performed at low consistency, wherein the pulp is diluted with an apparatus (28) located after the pump (26) for said second consistency, prior to treatment at said consistency.
