[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1 to 4 As shown, the desulfurization bioreactor aeration device includes an aeration main pipe 1, which is connected to an air source. After the aeration main pipe 1 extends into the reactor, it is connected to a support pipe 2. The support pipe 2 is perpendicular to the aeration main pipe 1 and located in the center of the reactor. A turbine 3 is installed at the connection between the aeration main pipe 1 and the support pipe 2. Specifically, the turbine 3 is located inside the aeration main pipe 1. The lower end of the turbine 3 is mounted on the lower wall of the aeration main pipe 1 through a bearing, and the upper end is mounted on another bearing through a support rod 4. The turbine 3 is rotatably connected to the bearing. The upper end of the turbine 3 is fixedly connected to the inner wall of the support pipe 2 through a connecting rod 5.

[0028] The lower end of the support pipe 2 is connected to the aeration main pipe 1 by a sealed shaft.

[0029] At least two diagonal supports 6 are installed on the aeration main pipe 1. The upper ends of these diagonal supports 6 are fixed together on a ring 7. The ring 7 is fitted on the support pipe 2 and supports the support pipe 2, but does not affect the rotation of the support pipe 2.

[0030] The top of the support pipe 2 is integrally connected to the hollow aeration distribution plate 8. The aeration distribution plate 8 is circumferentially connected to the aeration branch pipes 9. These aeration branch pipes 9 are preferably evenly distributed radially around the aeration distribution plate. Each aeration branch pipe 9 is connected to several aeration branch pipes 10. The upper end of each aeration branch pipe 10 is connected to the aeration plate 11.

[0031] A protective cylinder 12 extends upward from the upper end of the aeration disc 11. The protective cylinder 12 is fitted with an end cap 13. The end cap 13 is preferably T-shaped, meaning that the diameter of the upper end of the end cap 13 is larger than the outer diameter of the protective cylinder 12. Two guide rods 14 are installed on the end cap 13, and two guide rings 15 are installed on the protective cylinder 12. The guide rods 14 are located inside the guide rings 15.

[0032] To facilitate the return of the end cap 13 to its original position, a return spring 16 is fitted onto the guide rod 14, with both ends of the return spring 16 fixed to the end cap 13 and the guide ring 15, respectively.

[0033] To prevent the end cap 13 and guide rod 15 from detaching from the protective cylinder 12, a limiting plate 17 is provided at the lower end of the guide rod 15.

[0034] The work process is as follows:

[0035] High pressure oxygen enters from the aeration main pipe 1, forms a strong impact on the turbine 3, the turbine 3 rotates, drives the support pipe 2 to rotate through the connecting rod 5, thereby drives the aeration branch pipe 9 and the aeration sub-pipe 10 to rotate, forms agitation to the solution in the reaction tower, high pressure oxygen from the aeration main pipe 1, the support pipe 2 (passing through the gap between the support rod 4 and the aeration main pipe 1), the aeration distribution plate 8, the aeration branch pipe 9, the aeration sub-pipe 10 is finally released to the reaction liquid in the form of micro-bubbles through the aeration disc 11, and is fully dissolved and diffused with the reaction liquid under the rotation agitation of the support pipe 2, improves the aeration effect.

[0036] When stopping aeration, the end cover 13 blocks the protection cylinder 12 under the action of the return spring 16, so that the solution and dirt are prevented from entering the pipeline from the aeration disc 11.
