A REACTOR FOR MIXING LIQUID, GAS AND SOLID MATERIAL

摘要

The reactor (10) comprises a vertical cylindrical reactor tank (11) and a concentrically within the reactor tank (11) positioned vertical draft tube (100). The draft tube (100) comprises a first conical portion (110), a first cylindrical portion (120), a second conical portion (130) and a second cylindrical portion (140). An axial flow impeller (20) is positioned at a lower end (122) of the first cylindrical portion (120) and a vertical shaft (35) extends upwards through an upper end (12) of the reactor tank (11). A baffle arrangement (180) is positioned within the second conical portion (130) and a gas supply device (170) is positioned within the draft tube (100) below the impeller (20).
