Description
Technical field
The invention belongs to technical field of metallurgical iron-making devices, particularly a kind of blast-furnace slag processing system.
Background technology
At present, smelting iron enterprise both at home and abroad handles to blast-furnace slag that to be generally advection method (conventional bath method), INBA method and wheel method etc. several.Wherein advection method (conventional bath method) have simple in structure, the advantage that blowing rate of slag is high, but its floor space is big, mechanize, level of automation is low, carries the slag-water slurry energy consumption big at a distance, environmental pollution is bigger.INBA method and wheel method have the mechanization degree height, environment protection is good, quantity of circulating water is little, the advantage that power consumption is low and security of system is high; But because INBA method and wheel method to the treatment process of the small slag particle that passes filter screen that produces in the grain slag punching out process are: utilize slag stock pump or penumatic elevator that the slag-water slurry of settling bath bottom is returned the water trap secondary filtration.The shortcoming of this method is: 1. slag stock pump or penumatic elevator wear and tear easily, and small slag particle secondary filtration weak effect, increase machine utilization.2. in order to prevent the deposition of small slag particle, need in the settling bath bottom stirring pump or jet compression air to be installed, this method has increased the concentration of grain slag suspended particle in the recirculated water, has increased the wearing and tearing of circulating water system pipeline and equipment.INBA method and wheel method need standby dried pit for the reliability that improves system, and dried pit has floor space big, and the production process environmental pollution is serious and cleaning equipment expensive and the shortcoming of dried slag deficiency in economic performance.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, relative merits at advection method and wheel method, make corresponding improvement respectively, and they are combined, need not small slag particle secondary filter system to provide a kind of, need not that standby dried pit and small slag particle are removed thoroughly, system is reliable, flushing cinder mode blast-furnace slag composite processing system flexibly.
For realizing described order, blast-furnace slag composite processing system of the present invention includes slag ditch, slag Zhigou one, wheel method grain slag treatment unit, slag Zhigou two, cinder-flushing groove, advection method grain slag treatment unit; Wherein take turns method grain slag treatment unit pelletizer, dewatering unit, adhesive tape conveyor are arranged, advection method grain slag treatment unit has detritus pool one, detritus pool two, circulating water pool, water circulating pump, its structural feature is: slag Zhigou one links to each other with the pelletizer of wheel method grain slag treatment unit, and the backwater ditch that dewatering unit is provided with connects detritus pool one; Slag Zhigou two links to each other with cinder-flushing groove, and cinder-flushing groove links to each other with detritus pool one.
Described cinder-flushing groove comprises vapour collect cover, grain slag Punched box, back flushing pipe, vapour collect cover is located at the cinder-flushing groove top, the grain slag Punched box is located at the below that the cinder-flushing groove upper side is positioned at slag Zhigou two and cinder-flushing groove interface, and the back flushing pipe is located at the cinder-flushing groove bottom and is positioned at grain slag Punched box one side; Opposite side in the cinder-flushing groove bottom also has overflow weir, and cinder-flushing groove is connected by overflow weir and detritus pool one just; Zone between overflow weir and the cinder-flushing groove bottom forms water storage tank.
When equipment such as granulating device, dewatering unit and adhesive tape conveyor all move just often; the blast furnace hot slag enters slag Zhigou one; the blast furnace hot slag is the shrend granulation in granulating device; slag-water slurry separates in dewatering unit: water vapor is discharged by the exhaust steam tube that the dewatering unit top is provided with; the coarse particles grain slag is taken away by adhesive tape conveyor by hopper, and the small slag particle that passes filter screen flows into detritus pool one by the backwater ditch and carries out precipitation process.
When equipment failure, maintenance or slag flows such as granulating device, dewatering unit and adhesive tape conveyor are excessive; the blast furnace hot slag enters slag Zhigou two; when slag drops to cinder-flushing groove; the high speed water bundle shrend cooling that is sprayed by the grain slag Punched box, the slag-water slurry after the shrend fall into the direct overflow of cinder-flushing groove plash and enter detritus pool and carry out precipitation process.
The present invention compared with prior art its advantageous effect is as follows:
1, need not standby dried pit, the blowing rate of slag height, environment protection is good, the economic benefit height.
2, the grain slag concentration of suspended particles is low in the recirculated water, and the system wear loss is low.
3, security of system is reliable, variation that can the flexible adaptation blast furnace quantity of slag, and can not become the limiting element of blast furnace ordinary production.
Arrange near casting house that 4, compact construction does not have remote pulp water input.
5, equipment and facility are simple, and construction investment is few, and running cost is low, operation and easy to maintenance.
