Abstract
The utility model discloses the cold flare line structure of a kind of Coal Chemical Industry 300Kt synthetic ammonia liquid nitrogen washing, it comprises torch gas house steward (1), cold torch tracheae (2), cold torch gas fills with (3) and steam pipe (4), cold torch tracheae (2) is connected to cold torch gas and fills with on (3), the escape pipe (5) that cold torch gas fills with (3) is connected with torch gas house steward (1), steam pipe (4) is connected on escape pipe (5), on escape pipe (5), the tie point of steam pipe (4) is connected with knockout drum (6) to torch gas house steward (1) interface section, knockout drum (6) is provided with drain valve (7).The utility model increases a set of gas and water separator on cold flare line, and installs steam trap additional, completely solves the hydrogen sulfide corrosion problem that cold torch gas causes because torch pipe network brought into by the condensate liquid adding steam generation.
Description
Technical field
The utility model relates to the cold flare line structure of a kind of Coal Chemical Industry 300Kt synthetic ammonia liquid nitrogen washing, belongs to
large-scale coal chemical industry synthetic ammonia, methyl alcohol product installation torch pipe network improving field.
Background technology
Torch is used for processing in petrochemical plant the special combustion plant of fuel gas or the steam that cannot collect and reprocess, and is the important measures ensureing safety in production, reduce environmental pollution.The flare gas safe that device discharges is transported to torch and carries out burning process by flare discharge pipe network, is the important component part of flare system.After new environmental law is implemented, safety in production and environmental protection more and more come more to come into one's own, and chemical plant installations keeps the large-scale development.Flare system is the important measures of chemical plant installations safety, stable, long-term operation and environmental protection, and therefore, the safe and stable operation of torch pipe network system is one of important safety measure ensureing Coal Chemical Industry process units.
In use often there is one " water attack " phenomenon in existing circuit design, its reason is containing hydrogen sulfide gas in torch gas, hydrogen sulfide is water-soluble in acid, produce corrosion, torch pipe network is finally caused to occur that circumferential crack appears in many places, cause the gas in torch pipe network to leak in atmospheric environment, there is great potential safety hazard, also employee to be operated at the scene and tours of inspection brings healthy harm simultaneously.Although repeatedly process online the crackle leaked in production run, effect is very not good, and potential safety hazard can not thoroughly be eliminated, and forms the normal large hidden danger of producing of restriction.
meanwhile, existingammonia Production device flare line is divided into hot flare line and cold flare line, in design, cold flare line enters showing tremendous enthusiasm torch pipe network after being heated by cryogenic gas by the steam of 0.5MpA and 2.5MpA, due to the defect in design, produce water attack and corrosion and brittle fracture under low temperature after causing cold torch gas to enter hot flare line, very large harm is produced to flare stack network operation and brings very large safety, environmental protection hidden danger to production.
Summary of the invention
The technical problems to be solved in the utility model is: the cold flare line structure of Coal Chemical Industry 300Kt synthetic ammonia liquid nitrogen washing, it comprises torch gas house steward, cold torch tracheae, the filling of cold torch gas and steam pipe, cold torch tracheae is connected to cold torch gas and fills with, the escape pipe that cold torch gas is filled with is connected with torch gas house steward, steam pipe is connected on escape pipe, on escape pipe, the tie point of steam pipe is connected with knockout drum to torch gas house steward interface section, and knockout drum is provided with drain valve.
Be connected with steam jet in the end of steam pipe, the steam direction of steam jet ejection is identical with the gas flow in escape pipe.
On escape pipe, the tie point of steam pipe to fiery knockout drum interface section is provided with temperature measuring equipment, and temperature measuring equipment is connected to the lower surface of escape pipe.
Compared with the prior art, the utility model increases a set of gas and water separator on cold flare line, and installs steam trap additional, completely solves the hydrogen sulfide corrosion problem that cold torch gas causes because torch pipe network brought into by the condensate liquid adding steam generation.For the steam jet problem of cold flare system, steam jet is transformed, the steam direction that steam jet the is sprayed gas that completely solves identical with the gas flow in escape pipe flow to problem.Because of cold flare line temperature measuring point due to caliber excessive, cause the complete distortion of temperature survey, temperature measuring equipment be connected to by this to the lower surface of escape pipe, solve measure inaccurate problem.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Detailed description of the invention
embodiment 1, as shown in Figure 1,the cold flare line structure of existing Coal Chemical Industry 300Kt synthetic ammonia liquid nitrogen washing comprises torch gas house steward (1), cold torch tracheae (2), cold torch gas fills with (3) and steam pipe (4), cold torch tracheae (2) is connected to cold torch gas and fills with on (3), the escape pipe (5) that cold torch gas fills with (3) is connected with torch gas house steward (1), steam pipe (4) is connected on escape pipe (5), for solving etching problem, on escape pipe (5), the tie point of steam pipe (4) is connected with knockout drum (6) to torch gas house steward (1) interface section, knockout drum (6) is provided with drain valve (7).For solve high temperature and high pressure steam flow to problem, steam jet (8) is connected with in the end of steam pipe (4), the steam direction that steam jet (8) sprays is identical with the gas flow in escape pipe (5), for solving thermometric problem, tie point to fiery knockout drum (6) interface section that is upper at escape pipe (5), steam pipe (4) is provided with temperature measuring equipment (9), and temperature measuring equipment (9) is connected to the lower surface of escape pipe (5).
