Description
Technical field
This utility model relates to a kind of coke drying device, and the coke particularly relating to a kind of coke bin is dried air-distribution device.
Background technology
Coke as blast furnace ironmaking fuel and reducing agent, its product quality and directly affect ironmaking quality and effect containing water stability
Benefit.China, as coke production big country, produces amount of coke per year and is about 4.76 hundred million tons, and wherein 200,000,000 tons use CDQ, burnt
Charcoal aqueous 1%, 2.76 hundred million tons use wet quenching, coke aqueous 4%～8%.
Wet quenching coke is directly entered blast furnace ironmaking without dry substantially.Owing to wet quenching coke moisture is too high or winter
When coke freezes, the coke powder sticking to coke surface is difficult to sift out before State of Blast Furnace, after entering blast furnace with coke, deteriorates blast furnace
Breathability so that affect smooth operation of furnace.Coke moisture content height blast furnace coke ratio increase (moisture increase by 1% coke ratio increase by 1.1～
1.3%)；When water content is more than 4%, then stove dust quantity substantially rises, smooth operation of furnace is deteriorated, and also can cause that top temperature is low to be caused
Degradation adverse effect under the hardening of dry method dust cloth bag, process pipe blocking, blast furnace gas calorific value.
Existing coke drying device is hot waste gas to be passed directly into coke storage bunker bottom dry wet coke, and hot waste gas exists
In coke bin random distribution bottom coke bin to coke bin top flow, coke from coke bin top to coke bin flows heat exchange.Because of it
Without air-distribution device bottom coke bin, hot blast at coke bin surrounding and center position skewness, cause coke bin surrounding and in anxious
Charcoal can not uniformly be dried by Synchronous Heating, and heat drying efficiency is low, and coke bin outlet coke moisture fluctuation is big.
Existing coke bunker (coke bin) is transformed so that it is integrate coke storage being dried is that to improve coke moisture uniform
The optimal path of property.At present, burnt storehouse coke storage before the State of Blast Furnace of the coke screening station of coke-oven plant and coke bin coke bunker, iron-smelter
Storehouse, and the most square cone bucket concrete silo such as the coke bunker of calcium carbide factory, can not affect normal production when transformation,
And in order to reduce cost, the transformation to warehouse should be the least.
Summary of the invention
This utility model provides a kind of coke and is dried air-distribution device, it is adaptable to existing coke bin transform as collection coke storage and is dried
Improvement project in one；The hot blast that can effectively solve to enter in storehouse is uniformly distributed, favorably storehouse inner rim and center position
The uniform heating of coke in realizing storehouse, thus improve the uniformity of coke bin outlet coke moisture；Existing system is changed simultaneously
Make little, small investment, instant effect.
In order to achieve the above object, this utility model realizes by the following technical solutions:

Upper surface lays abrasion-proof backing block respectively.
The outside in described annular passage, cross air channel and a word air channel is all coated with replaceable abrasion-proof backing block.
Described coke bin is circular coke bin or square coke bin.
Compared with prior art, the beneficial effects of the utility model are:
1) it is applicable to transform existing coke bin as and integrates the improvement project that coke storage is dried, and existing system is changed
Make little, small investment, instant effect；
2) use vane from bickering periphery ecto-entad air feed and central authorities' blast cap combines from central authorities' air feed from inside to outside of bickering
Air feed form, the hot blast that can effectively solve to enter in storehouse is uniformly distributed storehouse inner rim and center position, is advantageously implemented storehouse
The uniform heating of interior coke, thus improve the uniformity of coke bin outlet coke moisture；
3) due to central authorities' blast cap and the existence in cross air channel, coke bin central authorities choke flow is improved to a certain extent fast, coke bin
The shortcoming that surrounding choke flow is slow；
4) it is applicable to there is a need to coke and is dried the situation of storage, there is drying integrated, the simple in construction of storage, regulation spirit
The advantages such as work, reduced investment, low, the energy-conserving and environment-protective of operating cost；
5) coal chemical enterprise can utilize coke oven flue waste gas residual heat to enter the wet quenching coke in coke screening station and coke bin bunker
Row damping is dried；Integrated iron and steel works can utilize the low temperature waste gas of sintering circular-cooler Low Temperature Thermal waste gas or blast funnace hot blast stove to height
Wet quenching coke in the bunker of Jiao storehouse, stove stokehold carries out damping drying；Drying hot blast source wide, energy utilization rate is high.
