Description

Technical Field

[0001] The utility model relates to a cyclone dust collector for converter flue gas treatment, belonging to the technical field of dust collectors. Background Art

[0002] As disclosed in the cyclone dust collector with the publication number CN107744886A, which includes a dust removal barrel. An air inlet is provided at the upper part of the dust removal barrel, and an ash collection box is provided at the bottom of the dust removal barrel. An exhaust pipe is arranged inside the dust removal barrel. The exhaust pipe is of a cylindrical structure, and spiral guide vanes are arranged outside the exhaust pipe. A straight guide vane with a frustum structure is provided at the bottom of the exhaust pipe. An inverted cone is arranged inside the bottom of the frustum. After the air flow enters the cyclone dust collector, it directly makes a spiral movement downward under the action of the guide vanes, effectively suppressing the formation of the upper ash ring. During the process of rotational separation of dust particles, due to the existence of the spiral guide vanes, the dust particles moving inward can only fall on the vanes and are re-lifted by the high-speed rotating air flow for further separation, rather than being discharged along with the inner air flow. The existence of the guide vanes reduces the pressure loss generated by the rotation of the air flow.

[0003] Based on retrieval and analysis, we find that there are still deficiencies in the existing technology:

[0004] The wind direction swirling structure in the existing technology is an inner or outer swirling structure, which will cause the swirling flow direction to be easily deformed. Moreover, the inner side of the dust collector is relatively smooth and not convenient for dust collection, resulting in poor dust removal effect. And as the air pressure flows, the agglomerated dust particles are peeled off from the inner wall and fall off naturally during the discharge process, which will cause inconvenient falling off. Therefore, a cyclone dust collector for converter flue gas treatment is needed to improve the above deficiencies. Summary of the Utility Model
