Specific embodiment
With reference to the accompanying drawings, the function that the structure of this system is described in detail and is realized.
A kind of cyclone separator for coal-burning boiler comprising flue gas separation conducting element 1 is arranged for detecting coal-burning boiler
The velocity sensor 2 and control unit 3 of the flow velocity of flue gas out, the result control point that control unit 3 is detected according to velocity sensor 2
Operation from the scalable rotary table component 15 in conducting element 1, in which:
Separating conducting element 1 includes scroll casing type air intake vent 11, cylindrical sleeve 12, is welded on the cone of 12 lower section of cylindrical sleeve
Body cylinder 13, ash barrel 14, and the liftable rotary table component 15 of 14 bottom of ash barrel is set, in which:
Ash barrel 14 is set to the lower section of cone cylinder 13, is used to collect from cylindrical sleeve inner wall and cone cylinder inner wall
The coal particles in flue gas slid；
Liftable rotary table component 15 is used to reduce when flue gas is inverted to inside vortex from outer vortex because direction of rotation is prominent
The pressure loss caused by change comprising:
Round estrade 151 is set to the bottom of cone cylinder 13, and side is made of elastic material resistant to high temperature, top surface and
Bottom surface is made of steel plate；
Helical blade 152 is made of elastic material resistant to high temperature, is set to the outer surface of round estrade, and its by
Helical trajectory on down is consistent with the conduct direction of inside vortex；
Telescopic rod 153 is set to the inside of round estrade, and its upper and lower side is fixed with the top surface of round estrade with bottom surface respectively
Connection stretches under the driving of motor 154 and round estrade 151 is raised and lowered；
Flue gas is tangentially entered in cyclone separator by scroll casing type air intake vent, is formed outer be vortexed and is dropped to cone cylinder bottom
It forms inside vortex afterwards to rise, the coal particles in flue gas make centrifugal movement and are separated and fall into ash barrel；
Control unit 3 is configured as:
When the speed of velocity sensor detection flue gas is greater than standard speed value, show the speed for the outer vortex that flue gas generates
It is larger, biggish local pressure loss can be generated after reaching the mutation of bottom direction of rotation, the separating effect of flue gas can be generated
Negative effect then controls motor driven telescopic rod and stretches round estrade reduction, so that the distance between helical blade reduces, helical-blade
