The reactor (10) includes a vertical cylindrical reactor tank (11) and a vertical suction pipe (100) concentrically located in the reactor tank (11). The suction pipe (100) includes the first conical part (110), the first cylindrical part (120), the second conical part (130) and the second cylindrical part (140). The axial flow impeller (20) is located at the lower end (122) of the first cylindrical part (120), and the vertical shaft (35) passes upwards through the upper end (12) of the reactor tank (11). The partition system (180) is located in the second conical part (130), and the gas supply device (170) is located in the suction pipe (100) below the impeller (20). |
