Background technique
At present; the requirement of arranging outward smelter due to Environment Protection Policy is more and more higher; simultaneously in order to meet the requirement that ISO14001 improves smelter work site environments factor; integrate with international standard further; smelter sintering machine dedusting ash is improved to totally enclosed pneumatic conveying mode by the Automobile Transportation (semi-open-type or canned) in past; thoroughly solve the leakage in dedusting ash loading, unloading and transportation process, problem of splashing; improve work site environments, decrease the wasting of resources.
The general technology of sintering machine dedusting ash Geldart-D particle is: dedusting ash enters pipeline after entering bin type pump fluidisation, and conveyance conduit need be spaced a distance through air compensation device tonifying Qi supercharging, realizes the long-distance sand transport of dedusting ash; Simultaneously according to the product ash quantity of the different operating mode of sintering machine, by the conveying capacity (casting sand transporting system technique is identical with sintering dust separation ash transporting system, no longer repeats to set forth) regulating air compensation to control dedusting ash.
Smelter sintering machine dedusting ash recycles the air-transport system of link and is cast as in molding sand pipeline system, needs to set up air compensation device in the middle of long-distance transmission pipeline.Hardness due to fed sheet of a media is high large to abrasion of conveying pipes, causes the monometallic air compensation device life-span used in existing two links short; And adopt the air compensation device of monometallic lined ceramics material, because ceramic lining impact resistance is poor, when carrying high hardness medium, these two kinds of air compensation devices all cannot solve the problem that equipment attrition is serious, working life is short.
, in use there is following problem in current sintering machine dedusting ash Geldart-D particle link and the air compensation device being cast as the use of molding sand conveying process:
1, the monometallic air compensation device used in pulverized coal injection delivery technology is continued to use, because sintering dust separation ash contains through metallurgy sintered process metallic oxide, its density and hardness is much larger than the density of blast furnace pulverized coal, and fed sheet of a media is to the air compensation device wearing and tearing especially severe in pipe-line system.But above two kinds of structure air compensation devices, adopt conventional carbon steel manufacture owing to making material, abrasion resistance properties is poor, can't resolve high hardness, fed sheet of a media to the wear problem of air compensation device.
2, adopt follow-on air compensation device of compound lining stupalith, the technique adopted at present has:
(1), self-propagating technique; (2), high temperature sintering mosaic technology; (3), technique is pasted; (4) spraying coating process etc., but no matter the wear-resistant pipe of lined ceramics material adopts any adherence method, due to the inherent defect of the impact resistance difference of ceramic materials, when carrying the larger medium of the high hardness such as sintering dust separation ash and cast moulding, density, often because ceramic-lined taking the lead in comes off, cause equipment Fast Wearing, need often change, safety, requirement that is stable, conveying high hardness medium efficiently cannot be met.
