Abstract
The invention discloses a metal compensator for a high temperature resistant circulating fluid bed boiler. The metal compensator is formed by two corrugated pipe compensator bodies connected through a middle connecting pipe, and each corrugated pipe compensator body comprises an inner connecting pipe, an outer connecting pipe, a corrugated pipe, a ring plate, a flow guide pipe, a third ring sleeve, a first ring sleeve and a second ring sleeve, wherein an inner cavity and an outer cavity are formed in a cavity in the corrugated pipe, the outer cavity formed by the first ring sleeve, the outer connecting pipe and the corrugated pipe is filled with alumina silicate fiber cotton, and the inner cavity formed by the flow guide pipe, the third ring sleeve, the outer connecting pipe, the inner connecting pipe, a ring flange and the first ring sleeve is filled with fiber felts. As duplex thermal insulation and a labyrinth structure of the inner cavity are adopted, the thermal barrier effect can be remarkably improved, meanwhile, high temperature media are effectively prevented from being flushed into wave nodes, the high temperature resistant performance of the metal compensator is remarkably improved, and the service life of the metal compensator is remarkably prolonged. The metal compensator is further characterized in that gaps between the third ring sleeves and the flow guide pipes are filled with composite thermal insulation layers. The metal compensator is good in thermal insulation effect, high temperature resistant and long in service life.
Description
Technical field
The present invention relates to a kind of pipe safety device, specifically, the present invention relates to a kind of circulating fluidized bed boiler metal compensator.
Background technique
In the pipeline configuration of circulating fluidized bed boiler, can adopt at present the displacement producing in the alignment error of metal compensator bucking-out system and running.The medium passing through in metal compensator from the pipeline configuration of circulating fluidized bed boiler is high-temperature flue gas, therefore, require metal compensator to there is good resistance to high temperature and sealing requirements higher., although this structure can play certain heat-blocking action, there is certain defect in fiberfill fibers felt in the cavity of prior art metal compensator between bellows and inner connecting tube: the one, and the heat insulation and preservation effect of fibrofelt is bad, affects the effect of heat insulation of compensator; The 2nd, fibrofelt easily comes off from the gap of honeycomb duct fit, causes the loose of thermal-protective material in cavity, and high temperature media easily pours in node, makes the resistance to high temperature of metal compensator poor, and the working life of compensator is shorter.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high temperature resistant, the high temperature resistant circulating fluidized bed boiler metal compensator of long service life.
The present invention is achieved through the following technical solutions technical goal.
High temperature resistant circulating fluidized bed boiler metal compensator, is formed by connecting by middle adapter by two groups of corrugated expansion joints, and every group of corrugated expansion joint comprises inner connecting tube, externally connected pipe, bellows, ring flat-plate, honeycomb duct and ring set III; The axial preset clearance of inner connecting tube at described middle adapter and two ends is arranged side by side; The inwall of described middle adapter, inner connecting tube is provided with resistant to elevated temperatures castable; On the outer wall of described middle adapter, inner connecting tube, be fixedly connected with respectively relative ring flange; Between described relative ring flange, by externally connected pipe, be connected with bellows, form collocation structure; On the inwall of described middle adapter, inner connecting tube, be fixedly connected with respectively relative ring flat-plate; On described relative ring flat-plate, be fixedly connected with respectively ring set III, honeycomb duct; Described ring set III gap is linked on honeycomb duct; Its improvements are: also comprise ring set I, ring set II; One end outer wall of described ring set I is fixedly connected with on the inwall of externally connected pipe at one end, and the other end Spielpassung stretches in the other end externally connected pipe; In the cavity forming at ring set I, externally connected pipe and bellows, fill aluminosilicate fiber cotton; In honeycomb duct, ring set III, externally connected pipe, inner connecting tube, ring flange, ring set I, be provided with ring set II, form mazy type cavity, fiberfill fibers felt in cavity.
In said structure, filled composite insulating in the gap that described ring set III, honeycomb duct close.
In said structure, described composite, insulating layer is composited by high temperature resistant stainless steel silk screen parcel ceramic fiber blanket.
The present invention compared with prior art, has following good effect:
1. be provided with inside and outside two-layer cavity, in the external cavity that ring set I, externally connected pipe and bellows form, fill aluminosilicate fiber cotton, fiberfill fibers felt in the inner cavity that honeycomb duct, ring set III, externally connected pipe, inner connecting tube, ring flange, ring set I form, by dual heat insulation, add the maze-type structure of inner cavity, can significantly improve effect of heat insulation, also effectively deaden high temperature media and pour in node, significantly improve resistance to high temperature and the working life of compensator simultaneously.
2. filled composite insulating in the gap that ring set III, honeycomb duct close, can deaden high temperature media and pour in node, further improves resistance to high temperature of the present invention and working life.
3. composite, insulating layer is composited by high temperature resistant stainless steel silk screen parcel ceramic fiber blanket, can play better deadening high temperature media and pour the effect in node.
