Abstract
The utility model discloses a cyclone separator for sampling fly ash, which comprises the following components: a cyclone barrel body, a cyclone barrel cover, an air inlet tube, a ceramic ring and a ceramic air leading ring. The upper end of the cyclone barrel body is provided with the cyclone barrel cover. The cyclone barrel body is internally provided with the ceramic air leading ring. An air leading pipe in the ceramic air leading ring is communicated with an air discharging pipe in the cyclone barrel cover. An upper barrel wall of the cyclone barrel body is provided with an air inlet along a tangential direction and is communicated with the air inlet tube through the air inlet. The inner wall of the cyclone barrel body is provided with the ceramic ring which is provided with an opening that is corresponding with the air inlet. According to the cyclone separator, the ceramic is adopted for protecting the upper part of the cyclone barrel body and the air leading tube in the barrel body so that the wearing of the cyclone barrel body and the air leading tube does not occur easily. The cyclone separator for sampling fly ash furthermore has the following advantages: greatly prolonged service life of the cyclone separator, remarkable effect and low cost.
Description
Technical field
The utility model relates to a kind of cyclone separator, particularly a kind of wear-resisting type cyclone separator to flying dust collecting and sampling in the station boiler flue.
Background technology
Dust-collecting efficiency is higher because cyclone separator structure is simple, so use very extensive in the dust collection industrial process that utilizes strength to carry.In power industry standard DL/T 9262005 " from odd test Fly ash sampling method ", propose to use a kind of small-sized cyclone separator and collected flying dust.And also substantially all adopt this mode to gather ash sample in the device of present online detection unburned carbon in flue dust, then sample is offered device and carry out on-line analysis.Because dust-laden is more and flow velocity is higher in the flying dust, Whirlwind barrel and air entraining pipe can be worn and cisco unity malfunction very soon, thereby have increased user's maintenance workload greatly, have also caused loss economically to the user simultaneously.
Summary of the invention
Goal of the invention: in order to address the above problem, the utility model provides that a kind of Whirlwind barrel and air entraining pipe are not easy to wear, the Fly ash sampling cyclone separator of long service life.
Technical scheme: a kind of Fly ash sampling cyclone separator, it comprises Whirlwind barrel, whirlwind cover, air inlet pipe, ceramic annulus and ceramic bleed ring; Be provided with the whirlwind cover in the upper end of Whirlwind barrel, be provided with ceramic bleed ring in Whirlwind barrel, the interior discharge duct of the bleed pipeline in the ceramic bleed ring and whirlwind cover is communicated with; On the barrel of Whirlwind barrel upper end, tangentially offer air inlet, and be communicated with air inlet pipe by air inlet; Be provided with ceramic annulus on the Whirlwind barrel inwall, ceramic annulus is provided with opening, and opening is corresponding with air inlet.
Wherein, described air inlet is a rectangular shape.
Wherein, the width of described air inlet is less than half of the difference of ceramic internal radius and ceramic bleed ring air entraining pipe external diameter.
Wherein, described air inlet height is less than ceramic bleed ring length.
Wherein, described air inlet does not exceed the air entraining pipe port of ceramic bleed ring.
Wherein, described air inlet pipe interior bone is by the rectangular shape of circular gradual transition to air inlet.
Wherein, described Whirlwind barrel lower end is conical.
Beneficial effect: the utility model adopts pottery that air entraining pipe in Whirlwind barrel top and the chamber is protected, and makes Whirlwind barrel and air entraining pipe not easy to wear, can prolong the service life of cyclone separator greatly, and effect is obvious and with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As depicted in figs. 1 and 2, Fly ash sampling of the present utility model comprises Whirlwind barrel 1, whirlwind cover 2, air inlet pipe 3, ceramic annulus 4 and ceramic bleed ring 5 with cyclone separator.The top of Whirlwind barrel 1 is cylindrical shape, and the bottom is conical, and cylindrical shell upper end and whirlwind cover 2 are fixedlyed connected by screw thread, and the assurance cyclone separator seals, and Whirlwind barrel 1 and whirlwind cover 2 form for metal material processing.Be provided with ceramic bleed ring 5 near whirlwind cover 2 places in Whirlwind barrel 1, be provided with the bleed pipeline in ceramic bleed ring 5 centers along the cylindrical shell axial direction, whirlwind cover 2 is provided with the discharge duct that is communicated with the bleed pipeline.Offer air inlet 6 in Whirlwind barrel 1 barrel upper edge inwall tangential direction, and be communicated with air inlet pipe 3 by air inlet 6; Air inlet 6 is a rectangular shape, and its width is less than half of the difference of ceramic annulus 11 internal diameters and ceramic air entraining pipe 12 external diameters, and its height is less than ceramic bleed duct length, and the lower edge of air inlet 6 does not exceed the tap air channel port of ceramic air entraining pipe 12; Air inlet pipe 3 interior bone are by the rectangular shape of circular gradual transition to air inlet 13.Be provided with ceramic annulus 4 on the annular inner wall around Whirlwind barrel 1 is positioned at air inlet 6, ceramic annulus 4 and Whirlwind barrel 1 usefulness ceramic glue are pasted firmly, and the air inlet 6 on the Whirlwind barrel 1 is consistent with the aperture position on the ceramic annulus 4, overlap good.Because it is high a lot of that ceramic annulus 4 and ceramic bleed ring 5 hardness ratio iron and steel are wanted, so increase greatly the service life of original part easy to wear, thereby prolonged the whole service life of cyclone separator greatly.
When this separator uses, dust granules enters Whirlwind barrel 1 inside by air inlet pipe 3, and along with air-flow rotates in Whirlwind barrel 1, because effect of inertia, dust granules is close to Whirlwind barrel 1 inwall and is rotatablely moved, simultaneously because the existence of gravity, the continuous spiral of dust granules is descended, finally fall from Whirlwind barrel 1 bottom ash discharging hole, the ash discharging hole bottom need closely link to each other with a closed container, a spot of particle dust and air then are inhaled into the bleed pipeline of ceramic bleed ring 5, and discharge by the discharge duct of whirlwind cover 2, thereby realize the centrifugation of gas and dust granules.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
