SLOTTED DRAFT TUBE MIXING SYSTEMS

摘要

A draft tube mixing system or reactor wherein the draft tube contains slots, perforations, or cut-out sections that allow cross flow of fluid through the draft tube wall. The perforations or slots can be practically any shape, however, simple geometric shapes such as rectangles and circles are preferred for ease of manufacture. The perforations or slots are typically arrayed in columns along a substantial section of the draft tube. In a preferred embodiment, the quantity and position of the perforations are such that a fluid filling the draft tube is capable of cross flow through the draft tube wall along substantially its entire length.
