A static distributor is provided with a top surface that slopes upwardly from the center port opening through which chlorine dioxide and pulp stock are pumped into a bleaching tower. The upwardly sloping sides of the distributor provide a dish-shaped or concave configuration influencing the flow from the center port opening upwardly and outwardly toward the circumference of the tower. The static distributor is provided with side openings formed by vertical support plates. The vertical support plates are spaced about the circumferences of the concave or dish-shaped flow surface to support the same on a base and change the flow distribution so that a good portion of the flow is radial between the plates rather than vertical. The radial flow is mixed with the flow undergoing upward influence provided by the dish-shaped center portion of the distributor, which causes more complete mixing and the formation of a vortex-type flow in the bleaching tower. Together with the improved mixing, improved economics in energy and/or power costs are realized.
