 2. Working principle and structure

 Efficient shallow air flotation device is an advanced fast air flotation system that successfully applies the "shallow theory" and "zero speed principle" on the basis of traditional air flotation theory. Through careful design, it integrates flocculation, air flotation, slag skimming, and mud scraping, making it an efficient equipment for water quality purification treatment.

 The high-efficiency shallow air flotation device addresses the shortcomings of traditional air flotation tanks by designing its raw water inlet and purified water outlet as mobile devices, in order to shorten the time for bubbles to float in the raw water. This means that while the raw water flows towards the air flotation tank, the water distribution pipes in the tank move in the opposite direction of the raw water flow, causing the raw water entering the tank to be in a relatively static state. In this way, the bubbles in the water float vertically towards the water surface, The floating speed is close to the floating speed of solid particles in the raw water (4-10cm/min), so the suspended particles in the raw water can quickly float to the water surface, while the purified water under the floating slag remains in place. When the purified water collection pipe is moved here, the purified water can be discharged outside the pool. In order to synchronize the movement of the inlet and outlet, the machine is designed to be circular. The inlet and outlet pipes are placed on a rotating frame to rotate around the center. This moving water distribution method generates zero speed. The suspended solids in the raw water float from the water to the surface at a fast speed, and the raw water can meet the purification requirements in three minutes.

 
The high-efficiency shallow air flotation machine is cylindrical in shape, compact in structure, and has a shallow pool. Including components such as pool body, spiral water distribution mechanism, dissolved gas release mechanism, rotating frame, water collection mechanism, slag skimming mechanism, dissolved gas system, return water pipeline, and electrical control cabinet. The inlet, outlet, and sludge discharge are all located within the rotating area of the equipment. The water distribution mechanism, water collection mechanism, and dissolved gas release mechanism are tightly connected to the frame and rotate around the center of the tank. This device provides a complete set of equipment assemblies and control systems, which are combined with centralized and decentralized control to achieve optimal operation of the equipment.
