Specific embodiment
The hypergravity High Temperature Rotating deduster of the present invention is similar to cyclone dust collectors, but is different from common cyclone dust removal
Device makes dust-contained airflow rotate, and grit is separated from air-flow by means of centrifugal force and is trapped in wall, then by gravity
Effect makes grit fall into conical head, and the hypergravity High Temperature Rotating deduster of this patent is that use is more increasingly complex than fixed blade
The multi-layer cylinder of the straight triangular fin of band more efficiently drives dusty gas to rotate, and makes gas solid separation.With it is traditional
Cyclone dust collectors are compared, efficient, good separating effect, and dusty gas runner increases.
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
Referring to the drawings 1,2,5, hypergravity High Temperature Rotating deduster is by by motor 1, radial impeller 2, housing 3, shaft 4, set
Cylinder 5 forms.1 power of motor ensures to centrifuge the demand of high pressure classification inlet flow rate so that dusty gas obtains enough centrifugal force,
Success gas solid separation.5 length of sleeve is unsuitable long, in order to avoid prevent the shake of whole system and reduce dusty gas temperature.Spiral shell
It revolves shape spiral case 3-1 and cylindrical tube 3-2 to weld, but housing is unconnected with shaft.When shaft rotates, dust-laden is avoided
Gas is mixed with purification gas.The structure of radial impeller and housing is similar to cyclone separator, and rotation removes in advance in the housing
Dirt, radial impeller 2 are fabricated with 5 overall vacuum soldering processes of sleeve, and shaft 4 uses 310S heat-resisting materials, and sleeve 5 uses
2025 stainless steels it is possible to prevente effectively from particle wears housing, and can guarantee the steady of structural strength and operating.
Referring to the drawings 3, sleeve is composed of multiple concentric thin-walled cylinders, and triangle is housed between neighboring concentric thin-walled cylinder
Fin, multilayer concentric thin-walled cylinder are connected to a fixed by fin between layers, and the thickness of concentric drums is 0.2mm, together
The fin of heart cylinder interior be triangular fin, fin height 6mm, fin width 4mm, fin thickness 0.2mm.Dust-laden
Gas enters sleeve, and under the influence of centrifugal force, solid particle is thrown out of, and is trapped by the fin in sleeve, in gravity
Under, it is recycled in bottom.Multilayer thin-walled cylinder to ensure with one heart and circularity, axis rotation steadily, avoid the occurrence of significant shock.
Referring to the drawings 4, there is a truncated cone-shaped bearing block 7 in conical head 3-3 left sides solid particle exit, and effect is
The solid particle isolated is made preferably to converge at bottom, facilitates discharge, is recycled.
Referring to the drawings 6, high-temperature dusty gas is tangentially downwardly into the hypergravity High Temperature Rotating from gas inlet tube and removes
Inside dirt device, high-temperature dusty gas is avoided to be directly leaked into top wind turbine, inner tube wall of the gas along the cylindrical tube, from upper and
Under make spiral rotating movement, the larger particle of a part of grain size from air-flow will be separated by means of centrifugal force and be trapped in device
Wall, then by gravity grit is made to fall into conical head 3-3, realize the pre-separation of high-temperature dusty gas；When what is be rotated down
After air-flow reaches cone base, then upwards, into inside sleeve 5, sleeve 5 rotates at a high speed under the drive of motor 1, in centrifugal force
Under effect, solid particle is separated with gas in high-temperature dusty gas, is trapped by the fin in sleeve, afterwards in top radial direction leaf
Top spiral case is inhaled under the action of piece and is then discharged the hypergravity High Temperature Rotating deduster, completes dust removal process.
The foregoing is only a preferred embodiment of the present invention, not makees limitation in any form to the present invention, appoints
What those skilled in the art, without departing from the scope of the present invention, technical spirit according to the invention to
Any simple modification that upper embodiment is made, equivalent variations and modification, are still within the scope of the technical scheme of the invention.
