Abstract:
PURPOSE: A single thread cyclone fine particle separator using variable gas discharge pipes is provided to control the particle recovery efficiencies and pressure drop level. CONSTITUTION: A single thread cyclone fine particle separator using variable gas discharge pipes comprises a main body(1), a swirl inducing part(2), a gas exhausting tube(3), a length changing tool, a flow rate measuring tool(5), and a control unit(6). The main body has an enlarged part(11), a particle collecting part(12) and an inlet pipe(13). The high pressure mixing gas is flowed into the inlet tube. The swirl inducing part is formed at the inner upper end of the main body and includes the inflow mixed gas to be closely attached to the inner wall of the main body.
