Description
Technical field
It the utility model is related to technical field of blast furnace process, and in particular to a kind of blast furnace water punching based on itself permeation filtration
Slag device, more particularly to it is a kind of by blast furnace itself production grain slag come carry out the blast furnace water-flushing-slag apparatus of itself permeation filtration with
Realize that pulp water separates.
Background technology
Blast furnace slag is the high-temperature fusion silicates material discharged when blase furnace cast iron is smelted from blast furnace.In blast furnace process
When, the components such as iron ore, fuel (coke) and flux are added from furnace roof, and hot wind and coal dust are blown into from air port, hot wind with
The fuel such as coke, coal dust burn in tuyere zone, there is provided load melting heat and the reducing agent of reduction of iron ore so that containing iron furnace
Material is constantly reduced and heated, when in-furnace temperature reaches 1400~1500 DEG C, material melting becomes liquid during decline
Phase, floats over molten iron upper strata, by iron mouth through the separation of sow skimming tool or slag by fully fusing and reduction reaction, liquid phase clinker
Mouth discharge, here it is blast furnace cinder.In modern blast furnace ironmaking production, the processing of blast furnace cinder is mainly carried out using water quenching method,
That is flush slag technique, accounts for blast furnace cinder processing more than 90%, dry Slag treatment mode is just used only in emergency management.
Bottom filter method is to use most Handling Blast Furnace Granulated Slag methods at present.Its technical process is:Blast furnace cinder is by porous spray
After the high speed water of head (pelletizer) injection carries out water quenching, the agitated groove of slag-water slurry (guiding device) enters filtering ponds.Filtering
The cobblestone filtrate that the bottom in pond is laid with multilayer (generally 3~4 layers) different-diameter filters slag-water slurry, by pulp water
Separation.Washing slag water after filtering continues cycling through utilization by pumping plant.Grain slag in filtering ponds by grab bucket directly catch entrucking (or
Belt feeder) outward transport.The residues processing technique is since equipment is few, and investment is small, and maintenance cost is few, easy to operate, obtained grain slag quality
Good, sewage is low without outer row, power consumption, and integrated operation cost is low, is Handling Blast Furnace Granulated Slag technique widely used at present.
On the other hand, it is selection and the paving of filtering layer of filtering material particle using the key of the Handling Blast Furnace Granulated Slag technique of bottom filter method
If.It is general to select cobblestone to be used as filtrate, in the fine grained cobblestone of the upper strata of filtering layer laying minor diameter, downward filtering layer successively
Filtering material particle diameter constantly increases, and the bottom of filtering layer selects cobblestone that diameter is about 20mm to form.Since cobblestone is filtered
The density of material is higher, and thickness is big, big to the pressure of filter tank bottom after multilayer cobblestone filtrate is laid with, and slag-water slurry
Into after filter tank, pressure bigger；Simultaneously because the high speed of slag-water slurry flows into, grain slag particle is easy to directly into filtering layer,
Destroy the sandwich construction of filtering layer；The fine particle and suspended matter of slag-water slurry, filtering is constantly rested on the impact of current
In duct, formed and blocked；When the water hardness of washing slag water is big, as water temperature raises after flushing cinder, calcium ions and magnesium ions are separated out in filtrate
Duct gap, causes filtering layer to occur hardened.All these problems, once occurring, will to filter in multilayer thick-layer filter structure
The filter capacity of layer drastically reduces, and rate of filtration fluctuation is uneven, ultimately causes filtering layer blocking, can not carry out normal filtration, must not
Filtrate is not replaced, increase maintenance cost, substantial amounts of discarded object can be also produced during filter material replacement.
