Abstract
The invention discloses a device and a method for high-alkalinity ore pulp long-distance pipeline delivery. A lye tank (1) of an alumina plant is connected with a long-distance delivery pipeline, the long-distance delivery pipeline is connected with a mine raw material grinding mill (2), the mine raw material grinding mill (2) is connected with a mine ore pulp tank (3) through a pipeline, and the mine ore pulp tank (3) is connected with an ore pulp tank (4) of the alumina plant through the long-distance delivery pipeline. The invention has simple structure and scientific design, greatly reduces the investment and the operation cost and adopts high-concentration lye to deliver the ore pulp without consuming fresh water, thereby being beneficial to the environment protection and reducing the water pollution.
Description
Technical field
The present invention relates to a kind of ore pulp conveying device and method, a kind of specifically ore pulp long-distance pipeline transporter and method.
Background technology
Along with fast development of national economy, the demand of aluminium oxide is also growing with each passing day, and interrogate according to generation China wealth: the output of China 1-12 in 2007 month aluminium oxide is 19,456,549 tons, increases by 42.02% on a year-on-year basis, and year consumption bauxite is also more than the forty-two million ton.In actual production process, alumina producer and mine are normally distant, tens kilometers even kilometer up to a hundred, and then bauxite need be grown apart from being transported to alumina producer.At present, the length of bauxite has railway, highway, water route and pipeline mode of movement apart from transportation scheme.When the mine is positioned at ungetable mountain area, when far away again apart from railway, highway, water route, from construction investment, operation, administrative expenses, the scheme that adopts long-distance pipe to carry is best selection.
Existing ore slurry pipeline conveying technology is both at home and abroad: bauxite is after the mine grinds, ore after water will grind is allocated as ore pulp, be transported to the alumina producing operation then, adopt filter that ore pulp is filtered then, filter cake after the filtration send the Baeyer digestion series with alkali liquor preparing after qualified, and filtrate send water treatment system to handle.The new water that this Technology Need consumption is a large amount of, need set up corresponding pulp dewatering operation, ore pulp filter cake and transfer ore pulp water are separated, need simultaneously filtrate filtered is taked corresponding water treatment measure, this technology must have corresponding pulp dewatering and water treatment operation, technology is comparatively complicated, and water consumption is big, and the balance of the water yield also is a difficult problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ore pulp long-distance pipeline transporter and method, and is simple in structure, design science; reduce investment and operating cost significantly; and adopt the high-concentration alkali liquor transfer ore pulp, and need not consumption of new water, help environmental protection and reduce the water pollution.
In order to address the above problem, the invention provides a kind of high-alkalinity ore pulp long-distance pipeline transporter, the lye tank (vat) 1 of alumina producer connects long-distance transmission pipeline, long-distance transmission pipeline connects mine raw material mill 2, raw material mill 2 is through the pulp tank 3 in pipeline connection mine, and the pulp tank 3 in mine connects the pulp tank 4 of alumina producer through long-distance transmission pipeline.
The pressure of mine pipeline delivery pump outlet is 7000～8000 kPas, and the distance of transfer ore pulp is 70～100 kilometers.
The discrepancy in elevation of mine and alumina producer is 40～70m.
A kind of high-alkalinity ore pulp long-distance applied pipeline transportation method, with pipeline the alkali lye of the high concentration of alumina producing operation is transported to the mine from lye tank (vat) 1 through long-distance transmission pipeline, bauxite is added raw material in proportion with the high-concentration alkali liquor that transports grind 2 operations, aluminium ore behind ore grinding slurry is transported to pulp tank 3, and the ore pulp of pulp tank 3 is transported to the pulp tank 4 in process for making alumina workshop with pump and long-distance transmission pipeline.
The two weight proportion of bauxite and the high-concentration alkali liquor that transports is 40%～55%.
Compared with prior art, the present invention is simple in structure, and design science reduces investment and operating cost significantly, and adopts the high-concentration alkali liquor transfer ore pulp, need not consumption of new water, helps environmental protection and pollutes with minimizing water.
Fig. 1 is a device schematic diagram of the present invention.
The specific embodiment
Embodiment: the lye tank (vat) 1 of alumina producer connects long-distance transmission pipeline, and long-distance transmission pipeline connects mine raw material mill 2, and raw material mill 2 is through the pulp tank 3 in pipeline connection mine, and the pulp tank 3 in mine connects the pulp tank 4 of alumina producer through long-distance transmission pipeline.
The pressure of mine pipeline delivery pump outlet is 7000 kPas, and the distance of transfer ore pulp is 90 kilometers, and the discrepancy in elevation of mine and alumina producer is 66m.
Carrying method of the present invention, with pipeline the alkali lye of the high concentration of alumina producing operation is transported to the mine from lye tank (vat) 1 through long-distance transmission pipeline, bauxite is added raw material in proportion with the high-concentration alkali liquor that transports grind 2 operations, aluminium ore behind ore grinding slurry is transported to pulp tank 3, and the ore pulp of pulp tank 3 is transported to the pulp tank 4 in process for making alumina workshop with high-pressure pump and long-distance transmission pipeline.
Bauxite is 46% with the high-concentration alkali liquor three's who transports proportioning.
