Description
Technical field
The utility model is related to spread furnace apparatus, more particularly to a kind of diffusion furnace Quartz stove tube.
Background technology
Existing diffusion furnace all inserts a blast pipe, its reactor off-gas in technical process using tail part exhaust from stove tail
Discharged from stove tail by stove inside exhaust pipe.As shown in Fig. 1, remaining waste gas can enter blast pipe from fire door in diffusion technique
Flow to stove tail and drain through tail washings bottle, due to discharge duct it is very long（2250MM）Wherein P2O5 stretches out through stove tail gas exhausting pipe
Duan Shi, because the rapid drawdown of temperature, and the steam of surrounding are reacted, generates the acrid liquid metaphosphoric acid P of thick shape2O5+H2O=
2HPO3 As thick shape metaphosphoric acid is in the aggregation of tail pipe wall（Now it can be seen that tailpipe is with the presence of a little liquid）, the P of process2O5
Microcrystal grain some can be attached on thick shape metaphosphoric acid here aggregation growth.There is the inclined phosphorus of above-mentioned generation again when meeting steam
The reaction of acid.The P for constantly adhering to2O5 Particle and the thick shape HPO for generating3The structure of similar concrete-like is formed until blocking up completely
Plug blast pipe（Whole process about 20-25 days）.And constantly blast pipe is corroded, blast pipe will rupture within -70 days 50 days.
From exhaust blockage until the whole technical process of fracture is all in uncontrollable state, cell piece quality can inevitably decline together
The rising of Shi Zaocheng maintenance costs and the shortening of maintenance period, while existing boiler tube is easily clashed into cracking by fire door, sealing is poor.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of diffusion furnace Quartz stove tube.
The utility model solves the technical scheme that its technical problem adopted：A kind of diffusion furnace Quartz stove tube, including
Boiler tube body, described boiler tube body one end closing, another end opening of the boiler tube body, the boiler tube body closes one end center
Air inlet pipe is provided with, the boiler tube body closes one end bottom and is provided with blast pipe and temperature tube, outside described boiler tube body openings one end
The face of cylinder is provided with flange, and boiler tube body openings one end inner side is provided with arc ring, and the blast pipe is located at the boiler tube body
It is curved that side is provided with " V " type for arching upward upwards, and the curved one end of " V " type extends to blast pipe with the boiler tube body joining place, institute
Arc ring width is stated more than the flange width.
Utilize " V " type curved so that waste gas is cooled down during climbing in above-mentioned design so that metaphosphoric acid is back in the pipe of road,
Blast pipe blocking is not easily caused, boiler tube body openings one end arranges flange and arc ring, be easy to improve at boiler tube body openings
Intensity, stress at release boiler tube body openings prevents boiler tube body from ftractureing, while arc ring and flange can increase sealing surface
Product, increases sealing effectiveness.
Used as the further improvement of the design, the blast pipe and temperature tube and the angle of vertical plane are 20 °, are easy to pipe
The arrangement of line, more accurately measures temperature in boiler tube.
Used as the further improvement of the design, the blast pipe is close to the boiler tube inner body wall, is easy to adding for blast pipe
Heat, the metaphosphoric acid after being effectively heated to reflux prevents metaphosphoric acid from blocking blast pipe.
The beneficial effects of the utility model are：The utility model utilizes " V " type curved so that waste gas is cooled down during climbing,
So that metaphosphoric acid is back in the pipe of road, blast pipe blocking is not easily caused, boiler tube body openings one end arranges flange and arc ring,
It is easy to improve intensity at boiler tube body openings, stress at release boiler tube body openings prevents boiler tube body from ftractureing, while arc ring
Can increase sealing area with flange, increase sealing effectiveness.
