Abstract
The invention relates to a low-shearing rotational flow air flotation device for removing suspended matters. The device comprises an inflow coagulation system, a rotational flow chamber and a pressurizing air injection system. The sewage containing the suspended matters and a coagulation drug are tangentially pumped into the rotational flow chamber and are mixed along a same direction under the effect of weak centrifugal force; when the mixture moves to an air injection section, micro-bubbles and the suspended matters are thoroughly collided, adhered and formed into a flocculating constituent; and the flocculating constituent is upward discharged along with the overflow and the clean water phase is discharged from the bottom. According to the invention, the efficient separation of suspended matters and water is realized through a series of physical and chemical processes; the whole set of device is free from motion part, is high in processing capacity, is convenient in operation and is stable in running; the low-shearing rotational flow air flotation device for removing suspended matters can be popularized and applied to chemical engineering and environmental protection industries.
