Abstract
The utility model relates to a kind of built-up type ammonia-feeding pipe of chemical industry ammonia decomposition furnace pipe, comprise the steel pipe be installed on flange, steel pipe is in-built is equipped with vitrified pipe, between the two ends of vitrified pipe and steel tube end part, device has end part seal ring, described vitrified pipe comprises more piece, and between the vitrified pipe of adjacent segments, device has middle part wear ring.The utility model adopts more piece vitrified pipe structure, can resist the corrosion of high temperature ammonia on the one hand, reduces tooling cost on the other hand; Be provided with the wear ring of angle staple, both facilitated the connection between adjacent ceramic pipe, and ensured sealing property, do not affect again the outer wall being placed on vitrified pipe of steel pipe, it has installs feature that is simple to operate, good sealing effect.
Description
Technical field
The utility model relates to chemical equipment technical field, particularly relates to ammonia destruction furnace.
Background technology
Preparing hydrogen by ammonia decomposition carries out in ammonia decomposition furnace pipe, and because the working temperature in flue is higher, ammonia has corrodibility to stainless steel under 400-500 DEG C of temperature condition, therefore, the work-ing life of the ammonia-feeding pipe of traditional stainless steel is short, and need periodic replacement, its cost is higher.
At present, the existing vitrified pipe that adopts is built in ammonia-feeding pipe structure in steel pipe, solve the etching problem of high temperature ammonia, but its shortcoming existed is: the integrally-built vitrified pipe of device in steel pipe, vitrified pipe due to length longer, its manufacturing cost promotes greatly.
Utility model content
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, provides a kind of built-up type ammonia-feeding pipe of chemical industry ammonia decomposition furnace pipe, its have unhurried current effective, improve sorbent material utilization ratio, feature that intake efficiency is high.
The technical scheme that the utility model adopts is as follows:
A kind of built-up type ammonia-feeding pipe of chemical industry ammonia decomposition furnace pipe, comprise the steel pipe be installed on flange, steel pipe is in-built is equipped with vitrified pipe, and between the two ends of vitrified pipe and steel tube end part, device has end part seal ring, described vitrified pipe comprises more piece, and between the vitrified pipe of adjacent segments, device has middle part wear ring.
Further improvement as technique scheme:
The upper and lower surface of described middle part wear ring respectively with the end contact of vitrified pipe, its inner and outer ring side is with the angle staple contacted with the inside and outside wall of vitrified pipe.
Described angle staple symmetry is positioned at the upper and lower surface of middle part wear ring.
The beneficial effects of the utility model are as follows:
The utility model adopts more piece vitrified pipe structure, can resist the corrosion of high temperature ammonia on the one hand, reduces tooling cost on the other hand; Be provided with the wear ring of angle staple, both facilitated the connection between adjacent ceramic pipe, and ensured sealing property, do not affect again the outer wall being placed on vitrified pipe of steel pipe, it has installs feature that is simple to operate, good sealing effect.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model.
In figure: 1, steel pipe; 2, vitrified pipe; 3, flange; 4, end part seal ring; 5, middle part wear ring; 51, angle staple.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the built-up type ammonia-feeding pipe of the chemical industry ammonia decomposition furnace pipe of the present embodiment, comprise the steel pipe 1 be installed on flange 3, steel pipe 1 is in-built is equipped with vitrified pipe 2, between the two ends of vitrified pipe 2 and steel pipe 1 end, device has end part seal ring 4, vitrified pipe 2 comprises more piece, and between the vitrified pipe 2 of adjacent segments, device has middle part wear ring 5.
The upper and lower surface of middle part wear ring 5 respectively with the end contact of vitrified pipe 2, its inner and outer ring side with the angle staple 51 contact with the inside and outside wall of vitrified pipe 2, the upper and lower surface of wear ring 5 in the middle part of angle staple 51 symmetry is positioned at.
The utility model adopts more piece vitrified pipe structure, can resist the corrosion of high temperature ammonia on the one hand, reduces tooling cost on the other hand; Be provided with the wear ring of angle staple, both facilitated the connection between adjacent ceramic pipe, and ensured sealing property, do not affect again the outer wall being placed on vitrified pipe of steel pipe, it has installs feature that is simple to operate, good sealing effect.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
