The important topic of technical staff's research.
Whirlwind powder selector is using the gas-solid mixture centrifugal force produced when making to rotate at a high speed, by dust from air-flow
The dry type gas-solid separation equipment separated.Conventional（Cut stream）The primary structure of tangential introducing-type cyclone separator is a circle
Conically shaped, cylinder epimere tangential direction is equipped with the blast pipe of certain depth in insertion tube equipped with a gas inlet pipe, barrel top,
There is the meal outlet for receiving fine powder at conically shaped bottom.Dust-contained airflow typically enters cyclone separator with 12-30m/s speed by air inlet pipe
When, air-flow will be changed into circular motion from linear motion.The overwhelming majority of swirling eddy, it is twist downward along wall from cylinder
Towards cone flowing.In addition, particle under the influence of centrifugal force, is thrown toward wall, grit is once contacted with wall, just loses inertia
Power, and fall by the momentum of the speed axially downwards near wall along wall, into ash releasing tube, collecting bag is fallen into by meal outlet
In.The outer rotational gas flow declined is rotated, is constantly flowed into during decline to the core of separator, forms centripetal radial direction gas
Stream, this fraction, which is just constituted, rotates upward inward eddy.The direction of rotation of inside and outside eddy flow is identical.Final purification gas
Outside through blast pipe displacer, a part of relatively dustshot got off that is not separated is also escaped therewith.
The said equipment is in use, the eddy flow of powder and air-flow in separator relies primarily on tangentially-arranged gas inlet pipe
Drainage is carried out, drainage effect is poor.
