As the air is continuously blown out, the water continuously rotates upwards with the air, forming turbulent flow, and the interface between the air and the water moves relative to each other, forming interface shear. At the same time, the air entering the upper air chamber from the upper row of air guide holes is blown out from the tiny gap between the rubber plate and the movable pallet to form tiny bubbles. Therefore, the utility model has both shearing air diffusion and blowing out of tiny bubbles, and the two methods are coordinated with the input of oxygen in the air to the sewage tank.
The utility model has the following advantages
1. High oxygen transfer efficiency. At present, many waste water diffusers have only the single function of hydraulic shearing or sending out tiny bubbles. The present utility model not only has the performance of turbulent flow and shearing diffusion of liquid, but also Release tiny bubbles, so the oxygen transfer efficiency is high.
2. No blockage. Due to the elasticity of the rubber disc and the reasonable structure design between the rubber disc and the movable pallet, and between the movable pallet and the disc body, when the air is stopped, the gap between the two air outlets is quickly closed. Causes blockage, which solves the thorny problem of clogged wastewater diffuser encountered by designers and managers for a long time.
3. Wide range of application Because of the ingenious design of the utility model and the selection of high molecular polymers as the material of the parts, it is suitable for sewage with various water qualities.
