Further, the feed inlet of the cyclone is connected along the tangent line or the spiral line of the circumference of the cylindrical section of the cyclone.
Further, the washing water inlet is fed along a tangent line of the circumference of the washing water ring.
Further, the cleaning water outlet is communicated with the cavity along the tangential direction of the circumference of the cleaning water ring.
Preferably, the washing water outlet is one or more.
Has the advantages that: the utility model provides a can prevent effectively that fine particle from polluting's high-efficient hierarchical swirler in the coarse grain, at the centrum section of swirler, follow the direction of rotation and introduce new medium rivers, carry out secondary fluidization or seepage flow to the sedimentary deposit that cylinder section and last conic section formed and wash, bring the fine particle that wherein smugglies secretly into interior whirl wherein to finally discharge along with the overflow, reach the mesh that reduces the underflow and press from both sides thin and improve hierarchical precision.
