Abstract
The utility model provides an inner side thermal insulation and resistance structure in the through-wall position of a collection box. The structure can effectively resist blowing of high-speed smoke to a packing thermal insulation structure, so that the shedding phenomenon of the packing thermal insulation structure cannot happen, nonmetal expansion joints on the outer side of a thermal insulation furnace wall can operate at the working temperature, the over-temperature phenomenon cannot be caused, the normal work life of each nonmetal expansion joint is ensured, and efficient and safe operation of a furnace is ensured. The inner side thermal insulation and resistance structure comprises the collection box and a thermal insulation furnace wall, wherein the collection box penetrates through the thermal insulation furnace wall, the packing thermal insulation structure is arranged in the position, where the collection box penetrates through the collection box, of the thermal insulation furnace wall, and after the collection box penetrates through the thermal insulation protecting wall, the nonmetal expansion joints are arranged between the outer side position of the collection box and the outer side of the thermal insulation protecting wall. The inner side thermal insulation and resistance structure is characterized in that a thermal insulating sheet is sleeved with the collection box at the position near the inner side wall of the thermal insulation furnace wall, and the inner annular surface of the thermal insulating sheet is tightly attached to the outer surface of the collection box.
Description
Technical field
The utility model relates to the technical field of waste heat boiler structure, is specially 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 speed flue gas, there is overheating problem, and then the overtemperature when operation of the non-metal expansion joint outside making, make non-metal expansion joint working life short, can not guarantee high efficiency boiler safe operation.
Summary of the invention
For the problems referred to above, the utility model provides the inner side insulation barrier structure at a kind of header place through walls, it can effectively stop that high speed flue gas is for the purging of filling insulation construction, make to clog insulation construction and there will not be obscission, and then the non-metal expansion joint that is incubated furnace wall outside can be moved under operating temperature, there will not be overheating problem, guarantee the normal working life of non-metal expansion joint, guarantee high efficiency boiler safe operation.
The inner side insulation barrier structure at a kind of header place through walls, its technical scheme is such: it comprises header, insulation furnace wall, described header is through described insulation furnace wall, the position through walls filling of described header and described insulation furnace wall has filling insulation construction, described header runs through between the external wall of outer fix after described insulation furnace wall and described insulation furnace wall and is 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, the outer surface of described heat shield covers after the inside region of all filling insulation constructions, the outer surface in its outside is close to the inside wall of described insulation furnace wall, the inner side, lower end of banking stop is welded to connect described insulation furnace wall, the inner surface in the outside of described heat shield is close in the inner side, upper end of described banking stop.
It is further characterized in that: described heat shield comprises 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, forms guiding cavity between the inside wall of described inner side steel plate and described insulation furnace wall, and insert in described guiding cavity in the outside of described heat shield.
Adopt after structure of the present utility model, because 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, the outer surface of described heat shield covers after the inside region of all filling insulation constructions, the outer surface in its outside is close to the inside wall of described insulation furnace wall, the inner side, lower end of banking stop is welded to connect described insulation furnace wall, the inner surface in the outside of described heat shield is close in the inner side, upper end of banking stop, banking stop has limited the movement of heat shield on header is axial, but do not limit it with header up and down or move left and right, heat shield effectively stops that high speed flue gas is for the purging of filling insulation construction, make to clog insulation construction and there will not be obscission, and then the non-metal expansion joint that is incubated furnace wall outside can be moved under operating temperature, there will not be overheating problem, guarantee the normal working life of non-metal expansion joint, guarantee high efficiency boiler safe operation.
