Abstract
This utility model provides a kind of boiler hanging pipe, including roof tube band steel, it is characterized in that, use three sections of sleeve structures, be cased with ground floor wear-resistant sleeve on base tube top, ground floor wear-resistant sleeve top passes second layer wear-resistant sleeve, and the welding support of second layer wear-resistant sleeve upper end hangs at roof tube adjacent two between band steel, be outside equipped with the dilatation joint of 10～20mm at second layer wear-resistant sleeve, peripheral area pours heat resistance concrete.Second layer wear-resistant sleeve uses 15CrMo steel pipe to process.This utility model intensity is high, and wearability is good, can greatly reduce booster phenomenon, reduces fault rate, makes boiler operatiopn more steady, effectively extends the service life of boiler, reduce spare parts consumption and maintenance load, it is ensured that what dry quenching system produced is smoothed out.
Description
Technical field
This utility model belongs to technical field of mechanical equipment, particularly relates to the hanging pipe of a kind of waste heat boiler.
Background technology
Along with promulgation and the enforcement of the new environmental law of country, coking plant, for the requirement also increasingly stringent of dry coke quenching operation, is compeled
Make dry quenching system must reduce fault rate.And as the waste heat boiler of dry quenching system major part, due to boiler use
Hanging pipe directly withstands on roof tube band steel, the most often occurs that periodic structure is damaged, the problems such as booster even occurs, not only
Add spare parts consumption and maintenance load, and directly affect the life-span of boiler and being smoothed out of dry quenching system production.
Summary of the invention
This utility model aims to provide a kind of solid wear-resisting, can reduce fault rate, and the boiler in prolonged boiler service life hangs
Hanging tube.
To this end, the technical solution that this utility model is taked is:
A kind of boiler hanging pipe, including roof tube band steel, it is characterised in that use three sections of sleeve structures, on base tube top
Being cased with ground floor wear-resistant sleeve, ground floor wear-resistant sleeve top passes second layer wear-resistant sleeve, and second layer wear-resistant sleeve upper end is welded
Connect support to hang between adjacent two roof tube band steels, be outside equipped with the dilatation joint of 10～20mm at second layer wear-resistant sleeve, outward
Exclosure side pours heat resistance concrete, can be incubated, and can keep again body of heater structural strength.
Described second layer wear-resistant sleeve uses 15CrMo steel pipe to process.
The beneficial effects of the utility model are:
Use result proves, this utility model intensity is high, and wearability is good, can greatly reduce booster phenomenon, reduces fault rate,
Make boiler operatiopn more steady, thus effectively prolonged boiler service life, reduce spare parts consumption and maintenance load, it is ensured that dry put out
What burnt system produced is smoothed out.
Accompanying drawing explanation
Fig. 1 is that pipe installment state schematic diagram hung by boiler.
In figure: base tube 1, ground floor wear-resistant sleeve 2, second layer wear-resistant sleeve 3, roof tube band steel 4, dilatation joint 5.
Detailed description of the invention
As seen from Figure 1, this utility model boiler hanging pipe, it is to use three sections of sleeve structures, i.e. adds on base tube 1 top and be cased with
Ground floor wear-resistant sleeve 2, ground floor wear-resistant sleeve 2 Upper Upper passes second layer wear-resistant sleeve 3, on second layer wear-resistant sleeve 3
End welding support hangs between adjacent two roof tube band steels 4, is outside equipped with the dilatation joint 5 of 15mm at second layer wear-resistant sleeve 3,
Peripheral area pours heat resistance concrete, can be incubated, and can keep again body of heater structural strength.Second layer wear-resistant sleeve 3 uses
15Cr1Movg steel pipe processes, and to improve the overall wear resistance energy of hanging pipe, increases the service life.
Claims (2)
1. a boiler hanging pipe, including roof tube band steel, it is characterised in that use three sections of sleeve structures, overlaps on base tube top
