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. Instead 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.

[ We claim:] [1.] For use in a flue gas treatment device having its interior divided by vertically spaced partition plates into a plurality of separate chambers, a plurality of gas dispersion pipes, each comprising:a generally straight, axially elongated, hollow cylindrical pipe body mounted for vertical disposition by a hole formed in one of said partition plates;a contraction pipe portion detachably connected to a top end of said pipe body and being formed as an annular member formed of resilient material having a downwardly constricting, curvilinear circumferential surface extending to, and being substantially flush with, an interior surface of said hollow cylindrical pipe body; andmeans for detachably connecting said contraction pipe portion to said pipe body including:a reinforcement pipe concentrically attached to said pipe body adjacent the top end thereof,an annular positioning ring attached to, and extending radially outwardly from, said reinforcement pipe; andannular recess means formed about a bottom end of said contraction pipe member for receiving said top end of said reinforcement pipe and said annular ring.
