GAS-LIQUID CONTACT GAS DISPERSION PIPE, AND GAS-LIQUID CONTACT METHOD AND APPARATUS USING THE SAME

摘要

A gas dispersion pipe into which gas is introduced through its top end portion and blown out from its bottom end portion into liquid for gas-liquid contact, and a method and a device for gas-liquid contact employing the gas dispersion pipe are disclosed. The gas dispersion pipe has its top end portion formed in a contraction pipe with its horizontal cross-sectional area decreasing downward and/or its bottom end portion formed in a nozzle structure with its horizontal cross-sectional area decreasing downward. In stead of making the gas dispersion pipe with its bottom end portion in the nozzle structure, a gas guide member with its horizontal cross-sectional area increasing downward may be disposed within the bottom end portion of the gas dispersion pipe.
