Description
Technical field
The invention belongs to nonferrous metallurgy process technology, be specifically related to matte granulation technology technology and device.
Background technology
In copper smelting process, generally first copper concentrate is smelted into matte, the main component of matte is the mixture of the sulfide of copper and the sulfide of iron, generally containing Cu30% ~ 60%.
Matte need to further blow in special converting furnace, could smelt into blister copper.Matte can be put in converting furnace and blow with molten state and solid-state two kinds of modes.Matte with solid-state input blowing generally need to be controlled certain granularity, needs to carry out granulation before putting into converting furnace.
General liquid matte granulation all adopts the mode of shrend.Shrend mode granulation matte, because high-temperature liquid state matte runs into water, the generation hydrogen sulfide gas that easily reacts can cause aqueous water vaporization in the short time simultaneously, easily blasts, and has higher potential safety hazard.Meanwhile, blast can produce noise, and shrend large water gaging used can produce waste water, easily brings environmental issue, and the matte particle after shrend just can be sent to next procedure after need to dewatering and be dried, and therefore expends again mass energy.
The method of matte granulation also has the compressed air of employing first liquid matte to be blown out to granule, and reusable liquid water carries out cooling.The problem of blast and generation noise when this technology has solved matte shrend, but still the matte particle solving after generation waste water and shrend need to dewater and dry problem.
Summary of the invention
The object of the invention is; dewater matte granulation technology and the device of exempting from of the liquid matte of a kind of compressed air and water smoke granulation is provided; its technique and device are simple, and low cost of manufacture, has overcome the explosion phenomenon in other matte granulation process; removed the process of shrend matte dehydration from; do not produce shrend waste water, solved potential safety hazard, prevented pollution; meanwhile, have advantages of easy to operate.
Solving the technical scheme that technical problem of the present invention takes is: with compressed air make water fogging for granularity be the water smoke that 10～65 μ m, pressure are 0.5～0.8MPa; spray to the molten matte being flowed out by chute; chute width is 100～200mm; molten matte flow velocity is 100～300mm/s; molten matte is dispelled and cooling curing is matte particle, freely fall to be arranged at granulating device bottom bury scraper plate transportation system.
The water yield and compressed-air actuated volume ratio 1:20～60 in the described water smoke that sprays to molten matte.
The structure of special facilities of the present invention is: in the granulating device housing of sealing, access chute, chute below arranges atomizer, and atomizer is connected respectively compressed air hose and feed pipe by water smoke pipe with three-way connection, and granulating device lower housing portion connects sedimentation bucket.
The exit width of chute is 100～200mm, and the distance of the outlet of atomizer and chute is 50～150mm.
Described granulating device housing top is connected to water smoke outlet, and sedimentation bucket bottom is provided with buried scraper conveyor, is connected to air control valve and air manometer on compressed air hose, is connected to water regulating valve and water pressure gauge on feed pipe.
Molten matte is flowed out by chute, with compressed air, make water fogging and from atomized water spray device, spray to molten matte for the water smoke with pressure, the gas of ejection and water smoke dispel the molten matte stream flowing down from chute into numerous tiny drops, be cooled to solid-state matte particle simultaneously, the water yield spraying into by adjusting and compressed-air actuated ratio, make above-mentioned gas and water smoke the matte droplet after dispelling is condensed into rapidly to dry sand shape solid granulates aloft, do not mix liquid water droplets, removed the process of traditional shrend matte dehydration from.Dry sand shape solid granulates freely fall to be arranged at granulating device bottom bury scraper plate transportation system, be transported to next procedure.The hot water and steam that granulation produces is from granulating device Base top contact.
The invention has the beneficial effects as follows: this matte granulation technology and device have overcome the explosion phenomenon in other matte granulation processes, removed the process of shrend matte dehydration from, do not produce shrend waste water; solved potential safety hazard; prevented pollution, meanwhile, had advantages of that technique is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is that the structure master of matte granulation device of the present invention looks schematic diagram.
Fig. 2 is the structure schematic side view of matte granulation device of the present invention.
In figure: 1-housing, 2-three-way connection, 3-compressed air hose; 4-air control valve, 5-air manometer, 6-water regulating valve; 7-feed pipe, 8-water pressure gauge, 9-water smoke pipe; 10-atomizer, 11-chute, 12-granulation matte; 13-transport vehicle; 14-buried scraper conveyor, 15-sedimentation bucket, the outlet of 16-water smoke.
The specific embodiment
Molten matte is entered in granulating device housing 1 by matte chute 11; compressed air in compressed air hose 3 blows to the water flowing out from feed pipe 7; by its atomization, be the water smoke with pressure; the air and the water that mix shape flow to atomizer 10 through water smoke pipe 9; becoming granularity is the water smoke that 10～65 μ m, pressure are 0.5～0.8MPa; atomizer 10 is 50～150mm with the distance of the outlet of chute 11; the gas of ejection and water smoke dispel the molten matte liquid flowing down from matte chute 11 into numerous tiny drops, are cooled to solid-state matte particle simultaneously.
By reasonably adjusting air control valve 4 and water regulating valve 6; make the water yield and compressed-air actuated volume ratio 1:20～60 in water smoke; just can guarantee the matte droplet after dispelling to be condensed into rapidly the particle of the solid-state granulation matte 12 of sand shape of dry suitable size aloft; from matte sedimentation bucket 15, drop to the buried scraper conveyor 14 of below; be transported to matte transport vehicle 13 and be transported to next procedure, the hot water and steam that granulation produces is drawn from the water smoke outlet 16 at granulating device top.In order to guarantee to obtain more suitable granulation matte 12, the exit width of chute 11 should be 100～200mm, and molten matte flow control is 100～300mm/s.
