[0023] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0024] like Figure 1As shown, the utility model shows a specific embodiment of a desulfurization solution oxidation air surplus recycling device, including a Roots blower 1, the vent of the Roots blower 1 is connected to the main air pipe 3, the main air pipe 3 is provided with multiple stages or multiple distribution pipes 4 connected to the main air pipe 3, and the other ends of the distribution pipes 4 are respectively provided with aeration pipes 6.

[0025] In this embodiment, the Roots blower 1 is used to provide a power source for surplus gas. The main air pipe 3 is connected to the vent of the Roots blower 1, and is used to recover the surplus gas of the Roots blower 1 and send it to the sulfur foam tank 7. The distribution pipe 4 is connected to the main air pipe 3, and is used to evenly distribute the surplus gas of the Roots blower in various areas in the sulfur foam tank 7. The aeration pipe 6 is connected to the distribution pipe 4 and is placed in the sulfur foam tank 7. The air holes on the aeration pipe 6 distribute the surplus gas distributed by the distribution pipe 4 to the sulfur foam tank 7, and the liquid in the sulfur foam tank is stirred by air pressure and flow to avoid sulfur deposition. The sulfur deposition in the sulfur foam tank can be reduced to below 0.2 meters by the blowing and stirring of the aeration pipe 6.
