Abstract
The invention relates to a unit () for deaeration of drainage water from a paper machine, said unit comprising an inlet () for receiving the drainage water in a first flow direction, an outlet () for removing the drainage water to a subsequent deaeration channel, and a first chamber () that is arranged downstream of the inlet, said first chamber comprising a first chamber part (), which comprises a guide wall portion () for redirecting the drainage water in a second flow direction that differs from the first flow direction, said guide wall portion being formed by a plurality of curved guide walls () which interact with the drainage water so that the drainage water is decelerated and air is forced out of the drainage water, and two end walls () which are arranged on respective sides of the guide walls, wherein each end wall of at least one of the flow channels exhibits an opening () that communicates with the flow channel for removing air that has been released from the drainage water in the flow channel. The invention also relates to a method for such a deaeration.
