PROCESS AND DEVICE FOR DEGASSING A PAPER STOCK SUSPENSION

摘要

Process and apparatus for degassing a flowing fibrous paper suspension. T he process includes separating the suspension into partial streams, spraying th e partial streams into a degassing chamber under vacuum, arid exposing the suspension to the degassing vacuum for at least 10 seconds. In this manner, gas within the suspension is separated from the suspension. The process also includes suctioning the separated gas out of the degassing chamber. The apparatus includes a degassing chamber structured to subject the suspension to a vacuum sufficient for degassing, a n element arranged at an inlet of said degassing chamber for dividing the suspension into a plurality of partial streams, and a suction device for removing separated ga s from said degassing chamber. The apparatus is structured and arranged so that the suspension is subjected to the degassing vacuum for a duration of at least 10 seconds.< /SDOAB>
