Efficient shallow air flotation equipment

Efficient shallow air flotation equipmentIt is an air flotation device that integrates coagulation, air flotation, skimming, sedimentation, and mud scraping functions. It generates a large number of fine bubbles through a dissolved gas system, allowing air to adhere to suspended particles in the form of highly dispersed small bubbles. By utilizing the principle of buoyancy, it floats on the water surface, thereby achieving solid-liquid separation. This device is particularly suitable for removing small suspended particles with a specific gravity close to water, such as oil, fibers, algae, etc.

working principle

The core components of an efficient shallow air flotation device include the tank body, rotating water distribution mechanism, dissolved air release mechanism, etc. These components are closely connected and rotate around the center of the tank body, achieving efficient treatment through careful design. The device adopts high-frequency common rail jet strong solution cutting technology, which generates strong centrifugal force through high-speed rotation. The micrometer level air integrated jet system enables the concentration of dissolved gas and water to reach the theoretical maximum value in a very short time, improving the manufacturing efficiency of microbubbles. In addition, the application of microsecond level rapid phase separation devices enables water molecules and air molecules in dissolved gas water to be rapidly separated in different directions in a very short time, forming uniformly charged small bubbles. These bubbles not only increase bubble density, but also change the surface tension of water, effectively adsorbing colored groups and some hydrophilic colloids.
