Centrifugal submersible aerator

Category：

The submersible centrifugal aerator has a direct-connected structure and is a self-priming aerator. The centrifugal force generated by the high-speed rotating impeller creates a strong negative pressure at the impeller inlet, drawing in air and water. In the mixing chamber, a certain proportion of air and water is mixed. Under the action of strong centrifugal force, the mixture is ejected along the tangent direction of the impeller through the flow passage, diffusing in the circumferential direction, causing the water flow to circulate in convection. The small and fragmented air bubbles have a large specific surface area and a slow rising speed, ensuring sufficient mixing with the water, thus achieving the effect of highly efficient oxygen-enriched aeration.

1. Equipment Overview:
The submersible centrifugal aerator has a direct-connected structure and is a self-priming aeration device. The centrifugal force generated by the high-speed rotating impeller creates a strong negative pressure at the impeller inlet, drawing in air and water. In the mixing chamber, a certain proportion of air and water is mixed. Under the action of strong centrifugal force, the mixture is ejected along the tangent direction of the impeller through the flow passage, diffusing in the circumferential direction. This creates a convective circulation of the water flow. The fine and small air bubbles have a large specific surface area and a slow rising speed, ensuring sufficient mixing with the water, thereby achieving the effect of highly efficient oxygen-enriched aeration.
2. Application Range:
Submersible centrifugal aerators are suitable for various wastewater biotreatment processes as dedicated aeration and mixing equipment.
3. Equipment Features
1. Self-positioning, easy installation, and can be freely arranged without interrupting process operation;
2. Compact design, utilizing self-priming function without the need for external air source;
3. Submersible operation of the main unit reduces floor space and noise;
4. Can be used directly in oxidation ponds, saving infrastructure costs;
5. Independent mobile aeration device with both aeration and mixing functions during aeration;
6. The chassis can be specially designed according to user requirements.
