Title:
VARIABLE CLASSIFICATION TYPE CYCLONE
Document Type and Number:
Japanese Patent JP3696929
Kind Code:
B2
Abstract:
PURPOSE: To adjust classification characteristics variably by installing more than one blade which can adjust an angle in the lower part of an inner cylinder installed to discharge purified gas outside with an opening in the lower part faced the upper part of a separation chamber.
CONSTITUTION: In a variable classification type cyclone equipped with a gas intake 1 for introducing exhaust gas and an inner cylinder 6 for discharging purified gas, more than one blade 7 which can adjust an angle is installed in the lower part of the inner cylinder 6. The blades 7 are connected interlockingly with each other by a link member and can change an angle by an actuator 9 such as a solenoid to be able to adjust classification characteristics changeably. In this way, when a revolving current collides against the blades 7, coarse particles loses inertia force and falls downward to be stored in a dust banker 4, while only fine particles are discharged from the inner cylinder 6 to be collected by a filter 11. In this process, a controller 8 computes a pressure loss on the basis of the signal of a pressure detection means 12 and controls the actuator 9 to minimize the pressure loss.
