In wind guide tank inside spin uplink, wind guide tank plays good guiding role close to cylindrical shell part circulation to flue gas, the part
Circulation is according to hand of spiral uplink, and the guiding role that the circulation far from cylindrical shell inner wall is subject to is less, therefore spiral
Trend it is relatively slow, so that circulation and close the circulation layering rising from cylindrical shell inner wall far from cylindrical shell inner wall,
It is referred to as inside circulation and outside circulation, the dust granule in the circulation of inside in this way can collide in contact zone, after collision
The momentum of dust reduce, can be sunk by leak hole, in sinking watching can and the dust granule of lower layer continue to collide so that its
His dust granule momentum reduces, and declines dust granule successively by leak hole, eventually enters into ash bucket, final to realize
Flue dust of flue gas during spiral uplink gradually is detached from, and the flue gas after dedusting is discharged by the smoke outlet tube at top.
Further, the spacing of the two adjacent ring wind deflectors is 0.4~0.8 times of cylindrical shell internal diameter, the model
Spacing in enclosing can be supplied to the enough spiral spaces of flue gas.
Further, the width of the wind deflector is 0.1~0.3 times of cylindrical shell internal diameter.
Further, the width of the wind deflector is 0.15 times of cylindrical shell internal diameter.
Further, the leak hole is round hole, and leak hole internal diameter is 0.3~0.7 times of the width of wind deflector.
Further, the axial length of the flue gas inlet tube is 0.5~2 times of cylindrical shell internal diameter, gas inlet
Pipe is connect with flue dust delivery outlet to be processed, thus flue gas inlet tube need enough length come to the direction of motion of flue gas into
Row guiding makes flue gas when entering flue gas inlet tube along section tangential direction.In addition, wind can be added before flue gas inlet tube
Machine promotes the kinetic energy of flue gas with this.
Further, the axial length of the flue gas inlet tube is 1.1 times of cylindrical shell internal diameter.
Further, the reducer pipe that the flue gas inlet tube can be gradually increased for diameter uniform straight tube or diameter.
Further, on-position height of the flue gas inlet tube on cylindrical shell is the 1/ of cylindrical shell height
At 10~1/2.
Further, on-position height of the flue gas inlet tube on cylindrical shell is the 1/ of cylindrical shell height
At 5, be conducive to the effect of rotating separation and sedimentation close to the on-position of cylindrical shell bottom end.
Further, the ash bucket is reverse frustoconic shell, and the big diametral plane of ash bucket is communicated with the lower end of cylindrical shell.
Compared with prior art, it is hardened to joined wind-guiding on the basis of original Cyclonic separating apparatus for the utility model
Structure, so which produces the collisions between the flue gas particle of two sides inside and outside the flue gas of upper rotation receives guiding role and be divided into, and
Declined by leak hole, form layer-by-layer sedimentation separation, enhance the effect of eddy flow, overcome internal disorder stream, improve
Isolated efficiency saves the occupied space of separation equipment.
