Abstract:
An apparatus for treating pulp with a gaseous reaction medium, comprising:a fluffer having a pulp inlet and a comminuting zone for receiving a mixture of a pulp and a gaseous reaction medium and for fluffing and refining said pulp in the presence of said gaseous reaction medium to produce a partially reacted pulp;a pulp static bed reactor having an inlet positioned directly below said fluffer for receiving said fluffed and refined pulp and gaseous reaction medium directly from said fluffer, whereby said fluffed pulp falls downward through an atmosphere of said gaseous reaction medium in said reactor, said reactor having a pulp outlet at a lower end thereof;a rotating distributor disposed in said reactor and spaced below said inlet for receiving said fluffed pulp falling downward through said reactor and for substantially uniformly distributing said pulp across the diameter of said reactor and forming a substantially uniform and homogeneous pulp bed having a substantially uniform upper surface and bed height; anda supply inlet for introducing a gaseous reaction medium into said reactor and passing said gaseous reaction medium through said pulp bed.
