Abstract
The invention discloses a kind of methods of dry coke quenching auxiliary hot repair heat preservation decompression, it is a kind of new and innovative maneuver for combining daily two kinds of operating methods of heat-insulation pressure keeping and decrease temperature and pressure, it takes and coke dry quenching furnace is kept the temperature, and boiler reduced pressure operation, this method is used when maintenance, it is not only scientific to save the repair time, the effective run time of dry coke quenching auxiliary is extended, while substantially increasing dry coke quenching yield.
Description
Technical field
The present invention relates to Dry Quenching Technology fields, more particularly, to a kind of side of dry coke quenching auxiliary hot repair heat preservation decompression
Method.
Background technique
It is domestic and after the every production run of world's large size dry coke quenching auxiliary 1 year due to the particularity of dry coke quenching auxiliary, according to
Convention should all carry out annual overhaul, and Baogang's dry coke quenching auxiliary is no exception, will carry out the annual overhaul of a wheat harvesting period time by a definite date every year, together
When our factory dry coke quenching auxiliary by north of china in winter climatic effect, each annual overhaul must be staggered half a year Heating Period, practical annual effectively fortune
The row time is only 10 wheat harvesting periods.
Summary of the invention
In order to solve the above-mentioned technical problem, the object of the present invention is to provide a kind of dry coke quenching auxiliary hot repair heat preservations to be depressured
Method, it is not only scientific to save the repair time, extend the effective run time of dry coke quenching auxiliary, substantially increase simultaneously
Dry coke quenching yield.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of method of dry coke quenching auxiliary hot repair heat preservation decompression, comprising:
S1 keeps the temperature dry coke quenching by coke dry quenching furnace；
S2 guarantees in coke dry quenching furnace insulating process the brick temperature at chute bracket position at 650 DEG C or more；
S3 should guarantee coke dry quenching furnace temperature for coke dry quenching furnace insulating process, boiler inlet temperature be reduced again, using to pot
Furnace, which carries out set water operation, reduces boiler inlet temperature；
S4, in coke dry quenching furnace heat preservation, long-time cold operation causes recyclegas combustible component exceeded, puts out using by dry
Furnace, which prestores chamber pressure and is adjusted to micro-positive pressure, to be diffused, to reduce combustible component.
Further, heat in coke dry quenching furnace is increased using stage dress coke in the S2, to guarantee chute bracket portion
The brick temperature of position is at 650 DEG C or more.
Compared with prior art, advantageous effects of the invention:
Putting out furnace chute portion successfully realizes the target of 650 DEG C of heat preservation or more, and boiler system, which realizes, is depressurized to normal pressure
State has successfully completed every upkeep operation, has reached ideal effect；By production run in 1 year, this method safely might be used
It leans on, it is not only scientific to save the repair time, the effective run time of dry coke quenching auxiliary is extended, while substantially increasing dry put out
Burnt yield；
By calculating, every set dry coke quenching is every can to save fund about 6,000,000 using the advanced maneuver of primary hot heat preservation decompression
Member in addition, dry coke quenching hot repair heat preservation is depressured first method there are very big promotion and application to be worth, overhaul dry coke quenching auxiliary
Period, which reaches 1.5 years or more, becomes possible, brings considerable economic benefit for dry coke quenching development.
Specific embodiment
A kind of method of dry coke quenching auxiliary hot repair heat preservation decompression, comprising:
S1 keeps the temperature dry coke quenching by coke dry quenching furnace；
S2, guarantee in coke dry quenching furnace insulating process the brick temperature at chute bracket position at 650 DEG C or more, using stage dress it is burnt come
Increase heat in coke dry quenching furnace, to guarantee the brick temperature at chute bracket position at 650 DEG C or more；
S3 should guarantee coke dry quenching furnace temperature for coke dry quenching furnace insulating process, boiler inlet temperature be reduced again, using to pot
Furnace, which carries out set water operation, reduces boiler inlet temperature；
S4, in coke dry quenching furnace heat preservation, long-time cold operation causes recyclegas combustible component exceeded, puts out using by dry
Furnace, which prestores chamber pressure and is adjusted to micro-positive pressure, to be diffused, to reduce combustible component.
By analyzing coke dry quenching furnace observing and controlling parameter, coke dry quenching furnace chute portion successfully realizes 650 DEG C of heat preservation or more
Target, boiler system, which realizes, is depressurized to normal pressure state, has successfully completed every upkeep operation, has reached ideal effect.
By production run in 1 year, this method was safe and reliable, not only scientific to save the repair time, extended dry coke quenching auxiliary
Effective run time, while dry coke quenching yield is substantially increased, and provide for our hot repair dry quenching system equipment
Thinking has established valuable practical experience.
By calculating, every set dry coke quenching is every can to save fund about 6,000,000 using the advanced maneuver of primary hot heat preservation decompression
Member in addition, dry coke quenching hot repair heat preservation is depressured first method there are very big promotion and application to be worth, overhaul dry coke quenching auxiliary
Period, which reaches 1.5 years or more, becomes possible, brings considerable economic benefit for dry coke quenching development.
By facts have proved: keeping the temperature the method being depressured when maintenance using dry coke quenching auxiliary hot repair, not only scientific section
The repair time has been saved, the effective run time of dry coke quenching auxiliary is extended, while having substantially increased dry coke quenching yield.By annual overhaul
(calculating by 30 days) shorten to item and repairs, and makes entirely to overhaul reality and has only just been fully completed with 3 days, and achieves good effect
Fruit can at least save the repair time 27 days in this way, substantially increase the efficiency of maintenance.It, can since dry coke quenching coke quality improves
Blast furnace feeding coke ratio is set to decline 2%~5%, while blast fumance ability improves about 1%.Blast furnace uses the coke production of dry coke quenching
Afterwards, dry quenched coke generates ironmaking using the program by this calculating than reduced rate 2%, blast fumance ability increase rate about 1%
Extension Benefit it is also considerable.
Embodiment described above is only that preferred embodiment of the invention is described, and is not carried out to the scope of the present invention
It limits, without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements, should all fall into claims of the present invention determine protection scope in.
