AI Technical Summary
Traditional dissolved air flotation equipment suffers from problems such as high energy consumption, unstable bubble generation, rapid sedimentation of suspended solids, and easy corrosion of equipment when treating wastewater with high oil content and high suspended solids, resulting in poor treatment effect and low operating efficiency.
The inclined tube vortex air flotation device includes a flocculation reaction tank, a vortex aeration tank, and an inclined tube packing air flotation tank. Through the combined treatment of flocculation reaction, vortex aeration, and inclined tube packing air flotation, the device utilizes the mechanical rotation to generate microbubbles and the blocking effect of the inclined tube packing, combined with a corrosion-resistant slag scraping device, to achieve efficient removal of suspended solids.
It improves the removal rate of suspended solids and oil, extends equipment life, reduces energy consumption, ensures operational stability and treatment effect, and solves the shortcomings of traditional equipment.
