Technology
1,AIR DISSOLVED SYSTEM:Unique technologyy----- High frequency common
railinjection,Powerful centrifugal force from high-speed rotation;
micron airintegrated injection system, the ratio of dissolved air
to water wasclose to the maximum value of Henry's law in 3 seconds
(27%),provide a platform for large scale micro bubbles, the
dynamicfactors are greatly reduced.
2,MICRO BUBBLEMANUFACTURING SYSTEM:Special structure for fast phase separation in microsecond, The 2
phases of watermolecules and air molecules in the dissolved gas
water are separated from each other indifferent directions in less
than 1 microseconds, form a uniform 3-7 m charge
bubbleInstantaneously, Under the condition of the same volume of
dissolved air, the bubbledensity is geometrically fission, Contact
area expansion of micro bubble flotation,improve the surface
tension of water molecules by integrated charged bubbles,accelerate
the bubble floating rate, adsorption of colored groups and some
hydrophiliccolloid. The dissolved air volume is a fixed value, the
service area of the micro bubble isinversely proportional to the
square of the diameter, the service area of the microbubble can be
expanded to hundreds of times, and the density of the micro bubble
isincreased to several thousand times, Theoretical research and
experimental resultsshow that the smaller the diameter of the micro
bubble, the stronger the adsorption ofsuspended matter.
