Description
Technical field
The utility model belongs to grain slag separating device field, is specifically related to a kind of blast furnace granulated slag pulp water shield retaining.
Background technology
In the processes such as ironmaking and copper metallurgy, nickel, lead, zinc, can produce the slag of a large amount of high temperature fused states, the treatment process of these slags roughly has two kinds: a kind of is traditional grain slag water quenching and natural cooling; Two is the broken and evaporations of Bao Er Water Company of Luxembourg grain slag water.These grain slags are former is a kind of waste produced in smelting, but if select water quenching process, the heat of grain slag just can be made to be fully utilized, turn waste into wealth.
Adopt above-mentioned grain slag water quenching, after grain slag dehydration, because the water ratio of grain slag is higher, can not transport immediately, in order to avoid the sewage in transport road in grain slag spills on road surface, affect environmental health, therefore, need to arrange control water grain slag field, grain slag is placed in grain slag field control water and reaches requirement to the water ratio of grain slag and just can be transported to other place, can not realize disposablely online completing dehydration in grain slag control water process, reach moisture requirement and directly to set out on a journey transport.
Mainly there is following defect in above-mentioned grain slag treatment process:
1, control grain slag field floor space large, the control water time is long, meets wind and plays dust pollution environment;
2, dewatering system maintenance is large, and labor strength is large, and running cost is high;
3, the calorific loss of washing slag water in dehydration, heat energy is not all recycled.
Method conventional is at present that grain slag is delivered to water slag groove, then delivers to the condensation of granulation tower, is expelled to granulating pit, then is delivered to grain slag field control water.Above-mentioned system and method, still can not solve moisture content height in grain slag needs special grain slag field to grain slag control water problem.
The people such as Wang Maohua deliver " Treating Methods for BF Slag " in the 2nd phase in 2006 total 338th phase " Anshan iron and steel plant technology ", disclose in this article, end filter method is adopted to process blast furnace slag, its technical process is: after the high pressure water that blast furnace slag is sprayed by porous nozzle in Punched box carries out shrend, Water Quenching Slag flows through shot tank and enters detritus pool, grain slag in detritus pool is caught by grab bucket and is deposited in the continuation dehydration of dry slag field, water in detritus pool and suspended substance flow into isolation tank by channel of allocation, gravel sealing coat is laid in isolation tank, and establish shaped steel to protect, washing slag water after isolation is reused after header is pressurizeed the cooling of feeding cooling tower by pump.
In above-mentioned method, the speed that grain slag is separated is still slow, generally needs the time of 3-4 days.Therefore, need to improve for above-mentioned defect, design a kind of pulp water shield retaining that can realize blast furnace granulated slag fast and be separated.

Embodiment
Below in conjunction with specific embodiment, the utility model is further described, so that those skilled in the art more understands the utility model, but does not therefore limit the utility model.
Embodiment 1
In granulating pit 1, pulp water shield retaining is set, three layers of sealing coat that this shield retaining comprises separation net 3 and is positioned at below separation net 3, three layers of sealing coat are the sealing coat I 4, sealing coat II 6 and the sealing coat III 7 that arrange from top to bottom successively, and sealing coat I 4, sealing coat II 6 and sealing coat III 7 are solid filler---pebbles.
The thickness of sealing coat I 4 is about 40cm, and the thickness of sealing coat II 6 is about 50cm, and the thickness of sealing coat III 7 is about 60cm.
It is the solid filler of diameter about 50mm in sealing coat I; It is the solid filler of diameter about 70mm in sealing coat II; It is the solid filler of diameter about 90mm in sealing coat III.
The material of separation net 3 is DN50 steel pipes, and separation net 3 is in square frame-shaped fenestral fabric, and the specification of grid is 1m × 1m.
Bottom granulating pit 1, below shield retaining, have water absorption tube 5, this water absorption tube 5 is connected with water suction pump, and by water suction pump effect, the water in the sealing coat above it pumps out by water absorption tube 5 fast, realizes pulp water and is separated.
Adopt above-mentioned pulp water shield retaining, pulp water can be realized be separated fast, the 72 hours original grain slag control water time is shortened to about 15 minutes by the utility model, process grain slag dewatering time is short, do not need grain slag field, grain slag dehydration after water ratio≤12%, direct Automobile Transportation, in transport, grain slag does not drip, floor space is little, and running cost is low, stable, good reliability, in dehydration, the heat of washing slag water can be recycled, and is a kind of energy-saving environment protecting waste processed technique.
Comparative example 1
If sealing coat is set to from top to bottom: sealing coat II, sealing coat I, sealing coat III; It is the solid filler of diameter about 50mm in sealing coat I; It is the solid filler of diameter about 70mm in sealing coat II; It is the solid filler of diameter about 90mm in sealing coat III.
Namely change the position of sealing coat, in every layer of sealing coat, the diameter of solid filler is constant;
Due to sealing coat II is arranged on the top, along with the carrying out of isolation, slag can fill the space of the solid filler of sealing coat II, slows down the isolation speed of pulp water; Result shows, in comparative example 1, isolation time can 30-40% longer than embodiment 1.
Comparative example 2
If sealing coat is set to from top to bottom: sealing coat III, sealing coat II, sealing coat I; It is the solid filler of diameter about 50mm in sealing coat I; It is the solid filler of diameter about 70mm in sealing coat II; It is the solid filler of diameter about 90mm in sealing coat III.
Namely change the position of sealing coat, in every layer of sealing coat, the diameter of solid filler is constant;
Result shows, in comparative example 2, isolation time can 50-60% longer than embodiment 1.
Comparative example 3
If sealing coat to be set to the thickness of 150mm, identical with embodiment 1 thickness, but only lay the solid filler that diameter is about 50mm in whole sealing coat; Dewater same slag, and the time in comparative example 3 is 1 hours; Longer than the time of embodiment 1.
Comparative example 4
If sealing coat to be set to the thickness of 150cm, identical with embodiment 1 thickness, but only lay the solid filler that diameter is about 70mm in whole sealing coat; Dewater same slag, and the time in comparative example 3 is 2 hours; Treatment time is longer than embodiment 1 far away.Analyzing, may be because solid filler diameter is comparatively large, the space of slag in isolation processes between the easy blocking of the carrying out along with isolation solid filler, thus slows down the speed of dehydration.
Comparative example 5
With comparative example 1 unlike, the thickness of sealing coat I 4 is set to about 25cm, and the thickness of sealing coat II 6 is about 30cm, the thickness of sealing coat III 7 is about 45cm, the thickness of whole sealing coat is 100cm, and the time of dehydration is 1.5 hours, also will be longer than the dewatering time in embodiment 1 far away.
As can be seen from above contrast, the setting of sealing coat of the present utility model be dewatering speed the most fast.Change the diameter of solid filler or the thickness of sealing coat, all can have an impact for dewatering speed.
