Abstract
The utility model provides a high temperature expansion compensator guide plate structure, including taking over wall, bellows, interior guide plate, outer guide plate, insulating layer, crown plate, pull rod, pouring the material, it is provided with the pull rod to take over the wall top, bellows parcel insulating layer passes takes over the setting of wall top surface, the insulating layer below has set gradually outer guide plate, interior guide plate, outer guide plate bottom side is provided with the crown plate, interior guide plate and crown plate welding, it pours the material all to be provided with on the inner face of takeover wall and interior guide plate. The utility model discloses pour the material with interior guide plate and the wear -resisting temperature resistant of taking over wall preparation an organic whole to guarantee in high temperature flue gas and bed material not direct contact, with the deflection that reduces the guide plate and erode, consequently overcome current guide plate and received high temperature flue gas and bed material to influence deformation, carbonization, erode, lead to the condition that equipment damaged, the device parks, improved circulating fluidized bed boiler life and guaranteed the circulating fluidized bed boiler safety steady operation.
Description
Technical field
The utility model relates to a kind of high-temperature expansion compensator deflector structure.
Background technique
In recirculating fluidized bed, between material returning device and lower furnace and material returning device standpipe place all establishes expansion appliance, make recirculation high-temperature flue gas and bed material get back to burner hearth continuously and stably from expansion appliance, FlexbleJoint utilizes effective dilatation of the elastic element bellows of FlexbleJoint to absorb the thermal expansion caused by high-temperature flue gas and bed material.As shown in Figure 2, in current technology, circular inner deflector 3 directly contacts with high-temperature flue gas and bed material, inner deflector 3 is subject to the effect of high-temperature flue gas and bed material, and with temperature generation mechanics performance variation, creep strain, surface erosion and guide plate carbonization phenomenon appear in inner deflector 3, very easily cause thermal-protective coating 5 to adhere to high-temperature flue gas after there is this situation to take away, make bellows 2 that scaling loss occur, thus life of equipment is declined, working efficiency reduces.Finally affect service life of equipment, economic loss and security risk.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of high-temperature expansion compensator deflector structure, this high-temperature expansion compensator deflector structure overcomes existing guide plate affects distortion, carbonization phenomenon by high-temperature flue gas and bed material, the situation causing device damage, device to stop, improves circulating fluidized bed boiler working life and ensure that circulating fluidized bed boiler safe and stable operation.
The utility model is achieved by the following technical programs.
A kind of high-temperature expansion compensator deflector structure that the utility model provides, comprises adapter wall, bellows, inner deflector, outer guide plate, thermal-protective coating, ring flat-plate, pull bar, pouring material; Described adapter wall top is provided with pull bar; Described bellows parcel thermal-protective coating is arranged through adapter wall end face; Outer guide plate, inner deflector is disposed with below described thermal-protective coating; Described outer guide plate bottom sides is provided with ring flat-plate; Described inner deflector and ring flat-plate welding; The inner face of described adapter wall and inner deflector is provided with pouring material.
Pouring material on described inner deflector inner face is wholely set with the pouring material on adapter wall inner face.
Described pouring material is wear-resistant temperature-resistant pouring material.
The welding position welding surplus of described inner deflector and ring flat-plate is greater than 40mm.
The size of described ring flat-plate is consistent with inwall passable size.
Described inner deflector is also provided with bitch to fix.
The beneficial effects of the utility model are: wear-resistant temperature-resistant pouring material inner deflector and adapter wall are made into one, to ensure directly not contact in high-temperature flue gas and bed material, to reduce the amount of deformation of guide plate and to wash away, therefore overcome existing guide plate to affect distortion, carbonization by high-temperature flue gas and bed material, wash away, the situation causing device damage, device to stop, improves circulating fluidized bed boiler working life and ensure that circulating fluidized bed boiler safe and stable operation.

Embodiment
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of high-temperature expansion compensator deflector structure as shown in Figure 1, comprises adapter wall 1, bellows 2, inner deflector 3, outer guide plate 4, thermal-protective coating 5, ring flat-plate 6, pull bar 7, pouring material 8; Described adapter wall 1 top is provided with pull bar 7; Described bellows 2 wraps up thermal-protective coating 5 and arranges through adapter wall 1 end face; Outer guide plate 4, inner deflector 3 is disposed with below described thermal-protective coating 5; Described outer guide plate 4 bottom sides is provided with ring flat-plate 6; Described inner deflector 3 and ring flat-plate 6 weld; The inner face of described adapter wall 1 and inner deflector 3 is provided with pouring material 8.
Further, exist cause problem not to be resolved for avoiding gap, the pouring material 8 on described inner deflector 3 inner face and the pouring material 8 on adapter wall 1 inner face are wholely set.
Specifically, described pouring material 8 is wear-resistant temperature-resistant pouring material.
Further, for ensureing enough welding performances, avoid the harmful effect that deformation brings, the welding position welding surplus of described inner deflector 3 and ring flat-plate 6 is greater than 40mm.
The size of described ring flat-plate 6 is consistent with inwall passable size.
Described inner deflector 3 is also provided with bitch fix.
