Description
Technical field
The utility model belongs to gaseous fuel burners, relates in particular to the not gas burner of premix.
Background technology
Coke-stove gas is through the desulfurization of vacuum potash method, and vacuum column parses H
2S gas adopts the claus reaction stove to produce monomer sulphur.In this production technology, the claus oven furnace head burner is vital equipment.Current, the burner of employing is provided with igniter burner, auxiliary burning nozzle and main burner, and three sections burners are by igniter burner gas pipe, igniter burner air hose, auxiliary burning nozzle gas pipe, auxiliary burning nozzle air hose, main burner air hose and main burner H
2The S tracheae is coaxial to connect and compose, the side pipe of above-mentioned all pipes by operated pneumatic valve respectively with gaspipe line, air pipe line and H
2The S air pipe connects, and operated pneumatic valve is connected with collecting and distributing control device DCS, and the terminal burner interior with placing claus oven of burner is connected, by three sections burner combustion processes of DCS control.
At first, starting ignition burner; When the DCS system detects the igniter burner place burning things which may cause a fire disaster is arranged, restart auxiliary burning nozzle, igniter burner cuts off coal gas and air automatically, quits work; When fire box temperature greater than 850 ℃, reach and possess H
2S gas is gone into the condition of stove burning, and main at last burner starts, H
2S gas and air burn through passage entering burner hearth separately, and auxiliary burning nozzle promptly quits work automatically.
Its defective is: three sections burner coaxial design, and the passage that source of the gas is provided is 6 layers, when main burner was worked, other 4 layers of passage quit work, because H
2S gas is non-clean gas, wherein contains a large amount of salts substances, in combustion process, produces a large amount of solid deposits; Under the furnace pressure about 8kPa, these deposits will cause passage to stop up attached in idle 4 layers of passage; Can't onlinely clean, have to carry out shutdown maintenance; Crouse's burner burner overall pulling down during maintenance rolls off the production line 6 passages is cleared up one by one, and maintenance is frequent, and furnace outage time is long, and directly influence is produced; H during maintenance
2The S toxic gas leaks, and causes environmental pollution; Moreover, be in claus oven temperature highest point with the terminal burner that is connected of three sections burners, temperature up to 1100-1200 ℃ between, H
2S gas at high temperature burns and has extremely strong corrosivity, and the corrosion obscission just appears in the combusting device stove burner operation in the time of 6 months, and service life is short, and the spare part loss is big, and operating cost is high.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of the utility model provides a kind of anti-clogging claus oven furnace head burner, solves the problem of passage obstruction of desulphurization system claus oven furnace head burner inoperative and burner seriously corroded, makes medium channel unimpeded; Normal operation of claus oven and stable sulphur output reduce H in the coal gas that dispatches from the factory
2S content prolongs burner service life, reduces spare parts consumption, reduces environmental pollution.
Anti-clogging claus oven furnace head burner comprises igniter burner, auxiliary burning nozzle and main burner, and these three sections burners are by igniter burner gas pipe, igniter burner air hose, auxiliary burning nozzle gas pipe, auxiliary burning nozzle air hose, main burner air hose and main burner H
2The S tracheae is coaxial to connect and compose, and above-mentioned all pipes are respectively by operated pneumatic valve and gaspipe line, air pipe line and H
2The S air pipe connects; Operated pneumatic valve is connected with collecting and distributing control device DCS; The terminal burner interior with placing claus oven of burner is connected, and by three sections burner combustion processes of DCS control, is characterized in establishing respectively on igniter burner gas pipe, igniter burner air hose, auxiliary burning nozzle gas pipe and the auxiliary burning nozzle air hose protection nitrogen arm; Be connected the manual opening-closing valve with nitrogen pipeline by manually-operated gate.During work, starting ignition burner at first, coal gas and the air passage through separately gets into burner hearth and burns; After DCS detects the igniter burner place burning things which may cause a fire disaster is arranged, start auxiliary burning nozzle automatically, coal gas and the air passage through separately gets into burner hearth and burns, and igniter burner promptly cuts off coal gas and air automatically, quits work; During greater than 850 ℃, reach H in auxiliary burning nozzle burner hearth temperature
2S gas is gone into the condition of stove burning, and automatic main burner starts H
2S gas and air burn through passage entering burner hearth separately, and auxiliary burning nozzle quits work automatically.When main burner is worked; Open four manually-operated gates, nitrogen gets into igniter burner gas pipe, igniter burner air hose, auxiliary burning nozzle gas pipe and auxiliary burning nozzle air hose, and nitrogen pressure is higher than furnace pressure; Both improved the pressure under the pipeline off working state; Again passage is separately purged, the solid particle after the burning is blown into burner hearth, thereby keeps above-mentioned four layers of passage unimpeded.
The utility model further improves, and described burner adopts acidproof, high temperature resistant stainless steel member, prolongs burner service life.
The utility model further improves again, and described protection nitrogen arm is connected with nitrogen pipeline, steam pipework, and realization nitrogen, steam uses separately or mix use.Control the catalyst internal junction carbon that the claus oven end flue temperature causes when preventing the water gas reaction imperfect combustion effectively and stop up, practice thrift nitrogen use level again.
Compared with prior art, advantage is:
The utility model is novel, compact conformation is reasonable, has solved the problem of obstruction of claus oven furnace head burner inoperative passage and burner seriously corroded, makes medium channel unimpeded, and burner is stable, helps producing carrying out smoothly; Prolong burner service life, reduced spare parts consumption, reduced environmental pollution, improved sulphur output, H in the coal gas that dispatches from the factory
2S content reduces.
