According to the slurry graded conveying and storage shared system, due to the fact that the slurry pipelines and slurry buffer storage spaces in different slurry conveying lines are shared, the utilization rate of devices in a slurry pipeline system is greatly increased, the fault rate of conveying of the slurry pipeline system is reduced, the cost is reduced, and the conveying efficiency of the slurry pipelines is overall improved.
Description
Technical field
The present invention relates to long-distance slurry pipe transportation technology field, relate to more specifically a kind of two line classifications that are applicable to iron ore concentrate slurry and carry the shared system in stirring chest space.
Background technique
In long-distance slurry pipe transportation technology field, according to the condition of technique batch feed, need to configure stirring chest and store slurry, existing iron ore concentrate slurry pipe-line transportation system as shown in Figure 1, relate to two independently transfer line A and B, pipeline A and B line all can be carried according to the difference of iron concentrate grade the slurry of different grades.Press actual operation requirements, low-grade (as 57 grades) slurry is transported to A Iron And Steel Plant by pipeline A line, and pipeline A line requires feed flow >210m
3/ h, 2 specification 12m(diameters of slurry storage Cushioning Design) × 12m(is high) stirring chest 1 and 2, the amount that upstream process is produced low-grade slurry is very little (as <105m
3/ h), thereby provide the feed flow requirement that cannot mate pipeline A to the slurry amount of supply line A, cause low-grade slurry yielding capacity to be significantly less than pipeline requirement feed flow, carry toward A Iron And Steel Plant so could pass through pipeline A after 2 stirring chests 1 of slurry storage buffering and 2 interior must being filled with.During long-distance slurry pipeline is carried, slurry grown place is often away from terminal.Above-mentioned slurry yielding capacity is significantly less than in the situation of requirements for pipes feed flow, and because the slurry storage buffer space of stirring chest 1 and 2 is limited, the slurry that makes to be delivered in pipeline A need to carry out batch mode conveying continually, every batch is sent the ore deposit time very short, frequent batch feed mode needs frequent water delivery flushing pipe, thus the serious waste of the water resources of causing and energy consumption.
As shown in Figure 1, high-grade (as 61 grades) slurry need to be transported to B Iron And Steel Plant by pipeline B on request simultaneously, and pipeline B requires slurry feed flow >280m
3/ h, 3 specification 16m(diameters of slurry storage Cushioning Design) × 16m(is high) stirring chest 3-5, the amount of upstream process production high-grade slurry is also very large (as >280m
3/ h), the feed flow that basic coupling pipeline B requires, yielding capacity requires the space of slurry storage buffering to dwindle with mating of quantity delivered, in fact 2 specification 16m(diameters) × 16m(is high) the storage buffering of stirring chest 4 and 5 can meet Production requirement, the stirring chest of carrying for pipeline B has the practical efficiency deficiency of 1 stirring chest 3 at least, causes the slurry storage waste of buffer space and the raising of construction cost.
In addition; as shown in Figure 1; in prior art, be delivered between the pipe-line system of different pipeline A, B and stirring chest system separate; in the time that wherein maintenance failure occurs a side, can cause like this shutdown of whole system; have a strong impact on manufacturing efficiency; such as in the time there is maintenance failure in supply line A wherein or stirring chest 1,2; whole pipeline A just cannot carry out slurry conveying; thereby whole slurry transporting system all need be in outage state; cause system equipment utilization ratio low, had a strong impact on manufacturing efficiency.
