Background technology
In the production of the industries such as alumina producing, what when manufacturing enterprise produces alumina product (or other products) by ore, form abandons Tailings Slurry, current device mostly with subsider take to connect 4 ~ 6 stage countercurrents step by step mode of washing reclaim useful slurries sodium aluminate solution in mine tailing slurries, the problem that process existence is collected in this mine tailing slurries washing is: technological process is long, the flow of processing is large, processing hourly water consumption is large, in this process, also make useful sodium aluminate solution concentration too be diluted, later stage is to keep the balance movement of technological process to need again to consume a large amount of steam to discharge the water yield unnecessary in production system, form a kind of pernicious circulation, not only waste a large amount of water resources, also make energy consumption too high.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, the dissolution fluid sedimentation separation that a kind of water consumption is few, energy consumption is low washing facility is provided.
The utility model solves the technical scheme that its technical problem adopts: this dissolution fluid sedimentation separation washing facility, comprise first grade subsides sink and the secondary sedimentation sink of sedimentation separation case and series connection, the sludge outlet pipeline of described sedimentation separation case bottom is connected with thickening filtration device, the filtrate (liquid of thickening filtration device connects thick liquid case by pipeline filtrate is stored as finished product, the sludge outlet of thickening filtration device connects the charging aperture of first grade subsides sink by pipeline, the sludge outlet of first grade subsides sink bottom connects the charging aperture of secondary sedimentation sink, secondary sedimentation sink top pipeline connects boiler, the liquid spill-way pipeline on secondary sedimentation sink top is connected to first grade subsides sink top, between first grade subsides sink and secondary sedimentation sink, realize the washing of adverse current two-stage.
The liquid spill-way pipeline on described first grade subsides sink top connects the inlet of dilution trap, and the discharging opening pipeline of dilution trap connects the charging aperture on sedimentation separation case top.
The liquid spill-way pipeline of described sedimentation separation upper box part connects thick liquid case spillage is stored as finished product.
The efficient separatory thickening filtration device of pressurization that the utility model adds mine tailing to separate in key link on mode of washing at subsider series connection 4 ~ 6 stage countercurrents step by step, the filter residue that first sedimentation goes out to sedimentation separation case carries out separation, filter residue after obtaining filtrate and concentrating, filter residue carries out sedimentation washing again, shorten washing flow, equipment is realized by continuous sedimentation separating technology and is changed sedimentation separation cooperation separation group technology into, shorten washing flow, with the mode of washing operation step by step of 2 ~ 3 stage countercurrents, wash water consumption reduces more than 20% on year-on-year basis.
Compared with prior art, the beneficial effect that dissolution fluid sedimentation separation washing facility of the present utility model has is: the utility model is due to the efficient separate, dedicated equipment of pressurization that adds mine tailing to separate, solve the choice for use of separation equipment, shorten washing flow, with the mode of washing operation step by step of 2 ~ 3 stage countercurrents, wash water consumption reduces more than 20% on year-on-year basis.The utility model is adding mine tailing separate the efficient separate, dedicated equipment of pressurization and reduce the sedimentation sink number of sedimentation separation on legacy equipment, change sedimentation washing into by continuous sedimentation washing separating technology and separate the combination that coordinates separation, shorten washing flow, improve the efficiency of production line, reduce the energy and use (steam, electricity), total energy utilization ratio is significantly increased.
