Abstract
The invention provides the inner side insulation barrier structure at a kind of header place through walls, it can effectively stop that high velocity smoke is for clogging the purging of insulation construction, make to clog insulation construction and do not have obscission, and then the non-metal expansion joint outside insulation furnace wall can be run at the working temperature, do not have overheating problem, guarantee the normal working life of non-metal expansion joint, it is ensured that high efficiency boiler safe operation.It includes header, insulation furnace wall, described header passes described insulation furnace wall, the position through walls of described header and described insulation furnace wall is packed with clogging insulation construction, described header run through described insulation furnace wall after outer fix and described insulation furnace wall external wall between be provided with non-metal expansion joint, it is characterized in that: described header is set with heat shield near the inside wall position of described insulation furnace wall, the interior anchor ring of described heat shield is close to the outer surface of described header.
Description
Technical field
The present invention relates to the technical field of waste heat boiler structure, the inner side insulation barrier structure at a kind of header place through walls.
Background technology
The header two ends of waste heat boiler pass from insulation furnace wall, the filling insulation construction of the position that header passes from insulation furnace wall comes off under the purging of high velocity smoke, overheating problem occurs, and then make the non-metal expansion joint operationally overtemperature in outside, make non-metal expansion joint working life short, it is impossible to guarantee high efficiency boiler safe operation.
Summary of the invention
For the problems referred to above, the invention provides the inner side insulation barrier structure at a kind of header place through walls, it can effectively stop that high velocity smoke is for clogging the purging of insulation construction, make to clog insulation construction and do not have obscission, and then the non-metal expansion joint outside insulation furnace wall can be run at the working temperature, do not have overheating problem, it is ensured that the normal working life of non-metal expansion joint, it is ensured that high efficiency boiler safe operation.
nullA kind of inner side insulation barrier structure at header place through walls，Its technical scheme is such that it and includes header、Insulation furnace wall，Described header passes described insulation furnace wall，The position through walls of described header and described insulation furnace wall is packed with clogging insulation construction，Described header run through described insulation furnace wall after outer fix and described insulation furnace wall external wall between be provided with non-metal expansion joint，It is characterized in that: described header is set with heat shield near the inside wall position of described insulation furnace wall，The interior anchor ring of described heat shield is close to the outer surface of described header，After the outer surface of described heat shield covers the inside region of all filling insulation constructions、Outer surface outside it is close to the inside wall of described insulation furnace wall，The lower end inside of banking stop is welded to connect described insulation furnace wall，The inner surface in the outside of described heat shield it is close to inside the upper end of described banking stop.
It is further characterized by described banking stop and includes outside band steel, inner side steel plate, and the outer end of described inner side steel plate is welded to connect the inner face of described outside band steel, and the outer surface of described outside band steel is welded to connect the inside wall of described insulation furnace wall；
Described inner side steel plate is specially the steel plate of circular configuration, and described heat shield is specially the steel plate of circular configuration, is formed and guide cavity between the inside wall of described inner side steel plate and described insulation furnace wall, and the outside of described heat shield is inserted in described guiding cavity.
nullAfter using the structure of the present invention，Owing to header is set with heat shield near the inside wall position of described insulation furnace wall，The interior anchor ring of heat shield is close to the outer surface of described header，After the outer surface of described heat shield covers the inside region of all filling insulation constructions、Outer surface outside it is close to the inside wall of described insulation furnace wall，The lower end inside of banking stop is welded to connect described insulation furnace wall，The inner surface in the outside of described heat shield it is close to inside the upper end of banking stop，Banking stop limits heat shield movement on header is axial，But it is not intended to it up and down or move left and right with header，Heat shield effectively stops that high velocity smoke is for clogging the purging of insulation construction，Make to clog insulation construction and do not have obscission，And then the non-metal expansion joint outside insulation furnace wall can be run at the working temperature，Do not have overheating problem，Guarantee the normal working life of non-metal expansion joint，Guarantee high efficiency boiler safe operation.
