Description
Technical field
The present invention relates to metallurgy industries to smelt iron field, and particularly a kind of blast furnace grain slag system filtering ponds steam disappears white dress
It sets.
Background technique
It can be generated when blast furnace process high-temperature liquid state slag (1350 DEG C -1500 DEG C), domestic annual 700000000 tons of molten iron of production produces
Raw 2.5 hundred million tons of high-temperature liquid state slag.Precipitating filtration method (often claiming bottom filter method) grain slag technique is generallyd use both at home and abroad to carry out slag
Processing.Hydraulic discharged slag is carried out before State of Blast Furnace, after being smashed slag with water quenching, is become slag-water slurry (often claiming grain slag), grain slag warp
Sluice enters filtering ponds, and liquid water is recycled after the filter layer filtering in filtering ponds, and solid-state slag particle is left in filtering ponds,
Then slag particle is grabbed by transporter grab crane, entrucking outward transport.
Since washing slag water water is more in filtering ponds, temperature is high, a large amount of sulfur-bearing steam is given out, especially winter temperature is low,
Quantity of steam is bigger.Water granulated slag steam has corrosivity, and surrounding enviroment are polluted in dissemination process, corrodes the equipment of surrounding, while by
It is close in distance of the filtering ponds away from blast furnace, therefore the steam distributed can also cause certain corrosion to blast-furnace equipment.
Increasingly severeer with Environmental Protection in China situation, more there is the disappear demand of white technology of filtering ponds steam in iron and steel enterprise
Strongly.The correlative study of many years has been carried out both at home and abroad, it is desirable to eliminate filtering ponds steam, it is white to realize that steam disappears.
Chinese patent CN202209390U, May 2 2012 publication date disclose a kind of " slag flushing movable cover plate power
Equipment transmission device ", in the patent by slag flushing movable cover plate covered in the way of reduce the external discharge of filtering ponds steam.
From Figure of description as can be seen that the cover board is since structure problem cannot realize thoroughly sealing to filtering ponds, during flushing cinder
With the increasing of pool surface quantity of steam is filtered, steam will necessarily be overflowed from the gap of cover board, cause steam contamination, corrosion week
Peripheral equipment.
Chinese patent CN202808827U, March 20 2013 publication date disclose a kind of " Slag treatment steam backwater
Device ", the device utilize the cover board of domes, make steam condensation and flow into catch basin.When quantity of steam is less in filtering ponds this
Kind of condensate return device, which can play a role, to be reduced steam and externally discharges, but the quantity of steam during flushing cinder in filtering ponds
Increasing, the speed for inevitably resulting in steam condensation is far smaller than the increased speed of quantity of steam, and final steam is from cover board gap
It overflows, causes environmental pollution.
Chinese patent CN108384908A 2018 publication dates August 10th, discloses a kind of " granulating pit steam condensation
Gas gathering mask is arranged in device and its gas gathering mask and application method ", the patent above filtering ponds, utilizes the demister inside gas gathering mask
Realize the white processing that disappears of steam of flushing cinder.Since filtering pool area is larger, length is 20m or so, thus to the bending resistance of gas gathering mask
Qu Qiangdu proposes very high requirement, which is arranged the entirety weight that multi-stage demister has aggravated gas gathering mask again inside gas gathering mask
Amount is easy to cause the overall structure of gas gathering mask to generate bending deformation.
By being analyzed above it is found that although the white side that disappears of blast furnace grain slag system filtering ponds steam has been provided in the prior art
Method, but there have various defects to have in different degrees of and different aspect to be to be solved, it is necessary to study new blast furnace grain slag system mistake
Filter tank steam disappears white device, effectively reduces environmental pollution caused by steam of flushing cinder.
