Abstract
The utility model discloses a combustion engine exhaust -heat boiler wall pipe high temperature expansion festival mainly forms by flange on the module expansion joint on the end backplate that contacts with the boiler and rather than the lower flange of combination, and the lower flange is equipped with the shroud ring outward, is equipped with nonmetal surrounding layer between last flange and lower flange, is equipped with the alumina silicate fibre cotton in nonmetal surrounding layer. The waste heat wall pipe passes end backplate and interior apron, and the bottom and the interior apron top of end backplate are equipped with the connecting frame, and the connecting frame is equipped with the endocyst hoop outward, is equipped with the surrounding layer between connecting frame and wall pipe, is equipped with the alumina silicate fibre cotton in the surrounding layer. The utility model is suitable for a wall pipe high temperature expansion festival of combustion engine exhaust -heat boiler top and bottom.
Description
Technical field
This utility model relates to expansion joint, specifically a kind of combustion engine waste heat boiler wall pipe high-temperature expansion joint.
Background technology
The afterheat steam of combustion engine waste heat boiler drains into steam turbine power generation by number of modules wall pipe, due to
The reason wall pipe of thermal expansion is the most constantly to be subjected to displacement, so, wall pipe and boiler
Top or bottom guard plate need retention gap, but its intermediate gap must assure that again sealing, it is impossible to fume leakage,
The most commonly used device for preventing leakage, due to reasons such as structure design or materials, uses a period of time all
Quickly leak air phenomenon, causes flue gas to leak in a large number, not only pollutes environment, and reduces the thermal efficiency,
Thus cause the waste of resource.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of combustion engine waste heat boiler is through walls
Pipe high-temperature expansion joint.The technical solution of the utility model is as follows to achieve these goals:
This utility model mainly by the module expansion joint upper flange on the end backplate contacted with boiler and and its
The lower flange of combination is formed, and lower flange is externally provided with shroud ring, is provided with non-gold between upper flange and lower flange
Belong to surrounding layer, in nonmetal surrounding layer, be provided with aluminosilicate fiber cotton.Waste heat wall pipe through end backplate and
Inner cover plate, the bottom of end backplate and inner cover plate top be provided with connection framework, connect framework and be externally provided with interior shroud ring,
It is provided with surrounding layer connecting between framework and wall pipe, in surrounding layer, is provided with aluminosilicate fiber cotton.
This utility model compared with prior art, has following clear advantage and innovation.(1) design is closed
Reason, using effect is good.This utility model wall pipe in boiler to three layers of nonmetal surrounding layer are installed,
Aluminosilicate fiber cotton, multiple heat insulation and sealing are filled up in centre, can guarantee that poling does not leaks
High-temperature flue gas.(2) service life is long, and general device just damaged in 6 months, and this expansion joint can
Reach 1 year more than half.
This utility model is applicable to the high-temperature expansion joint of the wall pipe of combustion engine waste heat boiler top and bottom
