Description
Technical field
The present invention relates to coke Storage Techniques field, more particularly to a kind of coke to store damping integrated apparatus and in its base
The method for realizing coke damping on plinth using technique hot waste gas.
Background technology
Coke as blast furnace ironmaking fuel and reducing agent, its product quality and containing water stability directly affect ironmaking quality and
Benefit.China is as coke production big country, and it is about 4.76 hundred million tons to produce amount of coke per year, wherein 200,000,000 tons use Dry Quenching, coke contains
Water 1%, 2.76 hundred million tons use wet quenching, the aqueous 4%-8% of coke.
Coke is directly entered blast furnace ironmaking without drying substantially during wet quenching.Since wet quenching coke moisture is excessive
Or during the icing of winter coke, the coke powder for being adhered to coke surface is not easy to sift out before State of Blast Furnace, after entering blast furnace with coke, deteriorate
The gas permeability and then influence smooth operation of furnace of blast furnace.Coke water content height can cause blast furnace coke ratio increase, and (moisture often increases by 1% coke ratio
Increase by 1.1~1.3%)；When water content is more than 4%, then stove dust quantity substantially rises, and smooth operation of furnace is deteriorated, and can also cause furnace roof
Temperature is low, causes the adverse consequences such as dry method dust cloth bag is hardened, process pipe blocks, blast furnace gas calorific value declines.
Existing coke drying means is that hot waste gas is passed directly into coke storage bunker bottom to dry wet coke, and heat is useless
Gas in coke bin random distribution from coke bin bottom to coke bin at the top of flow, coke is exchanged heat to coke bin flows at the top of the coke bin.
Because its in coke bin bottom without air-distribution device, hot wind causes coke bin surrounding coke cannot be equal in coke bin peripheral direction skewness
Even Synchronous Heating drying, heat drying efficiency is low, and coke bin outlet coke moisture fluctuation is big.
The content of the invention
The present invention provides a kind of coke moisture control method of coke storage damping integrated apparatus, set in coke storage bunker bottom

Into；The upper chamber and lower chamber for independently of each other and closing ring-shaped air chamber, on the corresponding coke bunker cone bucket wall of upper chamber
Open up annulus and form annular passage；Lower chamber connects central blast cap by central air passage respectively, is connected by middle part air passage
Middle part blast cap, middle part blast cap and central blast cap are along high to being arranged at coke bunker centre from bottom to top；Upper chamber and lower gas
Outdoor is respectively equipped with air duct, and volume adjusting apparatus is set respectively in air duct.
The volume adjusting apparatus is electric rotating plate valve.
The diameter of the middle part blast cap is more than the diameter of central blast cap.
The sum of the quantity in the middle part air passage and central air passage is 3-8.
Based on a kind of coke moisture control method of coke storage damping integrated apparatus, including：
1) using the low temperature hot waste gas of sintering circular-cooler low temperature hot waste gas or blast funnace hot blast stove as dry source of the gas, Low Temperature Thermal
Exhaust gas air duct outside upper chamber is introduced in upper chamber, by annular passage from coke of the periphery into middle STRENGTH ON COKE bunker into
Row drying；
2) low temperature hot waste gas air duct outside lower chamber is introduced in lower chamber, and a part of low temperature hot waste gas passes through middle part air passage
Middle part blast cap is reached, is dried by middle part blast cap by coke of the middle part to the periphery in STRENGTH ON COKE bunker；Another part low temperature
Hot waste gas reaches central blast cap by central air passage, and by central blast cap, by center, the coke in STRENGTH ON COKE bunker carries out to the periphery
Drying；
3) air quantity into the low temperature hot waste gas in upper chamber and lower chamber can be adjusted by volume adjusting apparatus, made low
Warm exhaust gas is uniformly distributed circumferentially in coke bunker, and STRENGTH ON COKE carries out being evenly heated drying, improves outlet coke moisture
Uniformity.
Compared with prior art, the beneficial effects of the invention are as follows：
1) orlop even distributing wind device is used and supplied from inside to outside from circumferential annular air passage ecto-entad air feed, by central blast cap
Wind, the air feed form being combined by middle part blast cap by the outside air feed in middle part, the hot waste gas effectively solved into putting in storage are store in coke
In storehouse circumferentially be uniformly distributed problem, being evenly heated for coke in storehouse is advantageously implemented, so as to improve outlet coke moisture
Uniformity；
2) intake in each air passage is adjusted by volume adjusting apparatus, STRENGTH ON COKE moisture is accurately controlled；
2) due to there is provided central blast cap, central air passage, middle part blast cap and middle part air passage, being conducive to improve in coke bunker
The problem of choke flow is fast, surrounding choke flow is slow is entreated, realizes the even drop down of coke and drying in storehouse, it is same to reach coke storage
When adjust moisture purpose；
4) coke bin suitable for coke-oven plant and sieve coke bunker, stokehold Jiao's groove of iron-smelter, and the coke bunker of calcium carbide factory
Deng having the advantages that the drying integrated, flexible adjustment of storage, reduced investment, operating cost is low, energy-saving and environmental protection.
