Abstract

Esillä olevan keksinnön kohteena on menetelmä ja laitteisto massan käsittelemiseksi. Erityisen hyvin keksinnön mukainen menetelmä ja laitteisto soveltuvat käytettäväksi kemiallisen massanvalmistuksen yhteydessä tilanteissa, joissa massasta on poistettava kaasua ja jossa massaa on laimennettava.&sr;Keksinnön mukaiselle menetelmälle ja laitteistolle massan käsittelemiseksi, jossa menetelmässä massa siirretään ensimmäisestä, korkeammassa sakeudessa massaa käsittelevästä massankäsittelylaitteesta (5) toiseen matalammassa sakeudessa massaa käsittelevään laitteeseen (50), on ominaista, että massasta erotetaan kaasua mainittua toista sakeutta korkeammassa sakeudessa, massa pumpataan pumpulla (26) matalassa sakeudessa tapahtuvaan käsittelyyn, ja massa laimennetaan pumpun (26) jälkeen sijoittuvalla laitteella (28) mainittuun toiseen sakeuteen ennen ao. sakeudessa tapahtuvaa käsittelyä.&sr;(Fig. 2)The present invention relates to a method and apparatus for processing pulp. The method and apparatus according to the invention are particularly well suited for use in connection with chemical pulp production in situations where gas must be removed from the pulp and where the pulp must be diluted.&sr;The method and apparatus according to the invention for processing pulp, in which the pulp is transferred from a first pulp processing device (5) processing pulp at a higher consistency to a second pulp processing device (50) processing pulp at a lower consistency, is characterized in that gas is separated from the pulp at a higher consistency than said second consistency, the pulp is pumped by a pump (26) for processing at a low consistency, and the pulp is diluted by a device (28) located after the pump (26) to said second consistency before processing at the said consistency.&sr;(Fig. 2)
