Novel cyclone separator capable of effectively inhibiting top ash ring phenomenon

The invention relates to a novel cyclone separator capable of effectively inhibiting a top ash ring phenomenon, which comprises an exhaust pipe, an inlet, secondary air inlets, a column section and a conical section, and the two symmetrical secondary air inlets are arranged above a top plate of the column section. The two secondary air inlets formed above the top plate of the column section of the cyclone separator can introduce airflow with a certain flow speed and the flow direction the same as that of the axis of the cyclone separator, and when particles entering the cyclone separator form a top ash ring below the top plate, the introduced airflow can blow the particles forming the top ash ring to a separation space; therefore, the phenomenon of a top ash ring is reduced, wall surface abrasion is reduced, and the service life of the cyclone separator is prolonged. 本发明涉及一种可有效抑制顶灰环现象的新型旋风分离器，包括排气管、入口、二次风入口、柱段和锥段，所述柱段顶板的上方设置两个对称的二次风入口。本发明中旋风分离器柱段顶板上方设置的两个二次入风口会引入一定流速且流向与旋风分离器轴线相同的气流，当进入旋风分离器内部的颗粒在顶板下方形成顶灰环时，引
