Description
Technical field
The utility model relates to the technical field of shell-and-tube waste heat boiler, particularly a kind of improved waste heat boiler.
Background technology
In technological processes such as carbon monodixe conversion, synthetic ammonia, the conversion gas that exports out from reactor bottom, the temperature of synthesis gas (following general designation reacting gas) usually between 400 ℃～500 ℃, operating pressure is medium-pressure or high pressure.The main component of high temperature shift gas is H
2, CO, CO
2, water vapour and a small amount of special corrosive medium; The main component of high-temperature synthesis gas is H
2, N
2, NH
3Deng.Medium hydrogen dividing potential drop height, inflammable and explosive, and have high temperature special media corrosive environment, as the nitriding corrosion of high-temperature synthesis gas.
High-temperature reacting gas usually needs by the waste heat boiler heat exchange, enters next section flow process after the reduction temperature, presses saturated vapor in the by-product simultaneously.Reacting gas is walked the tube side of waste heat boiler.Because there is high temperature special media corrosive environment in tube side entrance side temperature height, warm anti-hydrogen corrosion resistant material during tube side must adopt.By heat recovery, the reacting gas temperature of tube side outlet side drops to about 220～280 ℃, material can adopt common in warm anti-hydrogen steel, and need not consider the corrosion of nitriding and other special media.But because the middle and high pressure of tube side and higher pipe, shell side temperature difference operating environment, waste heat boiler adopts U type tubular construction more, and tube side turnover oral-lateral need adopt commaterial, has caused the waste of material.
Simultaneously, because the pass partition of common U type tubular type waste heat boiler is provided with along the tube sheet diametric(al), tube sheet and bobbin carriage are divided into two symmetrical parts, a part contacts with the inlet high-temperature reacting gas, another part contacts with outlet low-temp reaction gas, causes having bigger thermal (temperature difference) stress with the pass partition contact position in pass partition both sides bobbin carriage and the tube sheet.When tube side is imported and exported the gas temperature difference above 80 ℃, just can produce significantly influence to the stress distribution of tube side.
When the heat exchanger tube of waste heat boiler is arranged according to common U type tubular type (the bend pipe center is point-blank), higher thermal (temperature difference) stress comprises following aspect to the influence of tube side:
1, because of the uneven overall temperature difference stress that produces that is heated, and because the stack of temperature difference strain produces bigger stress to tube sheet concentrates in layering dividing plate both sides.
2, the bobbin carriage cylindrical shell of mesohigh waste heat boiler and tube sheet often adopt and are welded to connect, and welding point produces thermal (temperature difference) stress near layering dividing plate both sides.
The maximum stress that higher thermal (temperature difference) stress and pressure medium produce on bobbin carriage, tube sheet is superimposed, makes peak stress in the metal material more near critical value, even transfinites.In high temperature hydrogen corrosion and nitriding corrosive environment, because the fragility of material itself can produce trickle crackle at the welding point place of tube sheet and heat exchanger tube, tube sheet and bobbin carriage during welding.Under the influence of high-temperature medium side hydrogen, nitrogen corrosion, higher peak stress causes the crackle expansion easily, thereby causes equipment part even global failure.
3, the mesohigh waste heat boiler often adopts the sealing of bobbin carriage end flange flat cover, it is bigger to import and export the medium temperature difference, will cause the pass partition both sides bobbin carriage axially non-homogeneous expansion of back that is heated, and destroys the perpendicularity of end face of flange and bobbin carriage axis, reduce the reliability of sealing, even cause seal failure.
