Abstract
The utility model relates to a fixed rotary ash ejector used for a furnace arch of a large power station boiler, and the fixed rotary ash ejector comprises an outer sleeve (1), an inner sleeve (2), a sealing ring (3) and a fixed rotary ash ejector (4). The fixed rotary ash ejector provided by the utility model has the advantages that a single-nozzle fixed rotary ash ejector is arranged vertical to the slope, a gun barrel is made from a heat-resisting material, the gun barrel rotates to eject ash after being put in a hearth for appropriate distance, fixed and mounted, and the angle of a nozzle, ash ejecting pressure and flow are theoretically calculated and then are adjusted on site, so that the best ash ejecting effect is achieved; and the fixed rotary ash ejector provided by the utility model adopts a key technology that sealing of the connecting part of the ash ejector and a boiler wall is solved and also can resist high temperature higher than 1000 DEG C.
Description
Technical field
The utility model relates to the boiler sootblower field, is specifically related to a kind of fixing rotary soot blower for the large-sized station boiler furnace arch, furnace nose.
Background technology
At present, the usually serious dust stratification in large-sized station boiler (300MW and more than) furnace arch, furnace nose position, mainly be because there is an acclivity at this position, natural flow by flue gas can only be taken away the part dust, also have quite a few to be deposited on the slope, dust stratification thickness reaches more than 1 meter after a while, has a strong impact on the heat absorption of this position heating surface; Long telescopic soot blower is subjected to the impact of installing space and gun barrel winding degree, can't be near slope, and it is also undesirable to blow grey effect.
The utility model content
The purpose of this utility model is exactly for the usually serious dust stratification in present large-sized station boiler (300MW and more than) furnace arch, furnace nose position, mainly be because there is an acclivity at this position, natural flow by flue gas can only be taken away the part dust, also have quite a few to be deposited on the slope, dust stratification thickness reaches more than 1 meter after a while, has a strong impact on the heat absorption of this position heating surface; Long telescopic soot blower is subjected to the impact of installing space and gun barrel winding degree, can't be near slope, and blow also undesirable deficiency of grey effect, and a kind of fixing rotary soot blower for the large-sized station boiler furnace arch, furnace nose is provided.
The utility model is by outer sleeve, inner sleeve, sealing ring and fixing rotary soot blower form, perpendicular to having the outer sleeve installing hole on the boiler furnace arch slope face, outer sleeve is installed in the outer sleeve installing hole on the slope, and outer sleeve one end and slope are positioned on the same level face, the outer sleeve two ends are respectively the ash gun pipe installing hole of inner sleeve installing hole and fixing rotary soot blower, sealing ring is installed in the inner sleeve installing hole place of outer sleeve, inner sleeve is installed in the outer sleeve, and an end is against on the sealing ring, the ash gun pipe of fixing rotary soot blower is installed in the inner sleeve, the inner sleeve other end links to each other with the fixing rotary soot blower, and ash gun Guan Yiduan is positioned at outside the ash gun pipe installing hole of outer sleeve.
The utility model has the advantages that: vertical slope is installed single injector fixing rotary soot blower, gun barrel is exotic material, the suitable distance that puts in burner hearth installs and fixes rear rotation and blows ash, nozzle angle and blowing pressure and flow calculate through theoretical, adjust to reach the best grey effect of blowing through on-the-spot again.Also having a key technology is exactly the sealing that has solved soot blower and furnace wall connecting portion, and can also bear the high temperature more than 1000 ℃.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is by outer sleeve 1, inner sleeve 2, sealing ring 3 and fixing rotary soot blower 4 form, perpendicular to having outer sleeve 1 installing hole on the boiler furnace arch slope face 5, outer sleeve 1 is installed in outer sleeve 1 installing hole on the slope 5, and outer sleeve 1 one ends and slope 5 are positioned on the same level face, outer sleeve 1 two ends are respectively the ash gun pipe installing hole of inner sleeve installing hole and fixing rotary soot blower 4, sealing ring 3 is installed in the inner sleeve installing hole place of outer sleeve 1, inner sleeve 2 is installed in the outer sleeve 1, and an end is against on the sealing ring 3, the ash gun pipe 4-1 of fixing rotary soot blower 4 is installed in the inner sleeve 2, inner sleeve 2 other ends link to each other with fixing rotary soot blower 4, and ash gun pipe 4-1 one end is positioned at outside the ash gun pipe installing hole of outer sleeve 1.
