Detailed description of the invention
Technical scheme of the present invention is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
A stacked arrangement for petroleum coke, it adopt compacting layer by layer by lower and on trapezoidally store up driving surface, often spread one deck petroleum coke, carry out a compacting, repeatedly form a petroleum coke after compacting and pile up.
As shown in Figure 1, petroleum coke is discharged into and unloads coal in groove, then delivering to through travelling belt petroleum coke stack place, eventually pass stocker according to petroleum coke stacked arrangement petroleum coke stockyard stack just can.
Described compacting heap angular region is 45 ° ~ 75 °.
The height of compacting is each time 2.0 ~ 5.0 meters, when petroleum coke is stored up after thickness reaches 2.0 ~ 5.0 meters, with construction machinery and equipment by after its compacting, at the stacking second layer, store up from bottom to top successively, pile till requiring height always, it is 300 ~ 500mm that each compacting reduces thickness.
Its bottom-to-top-height of storing up is 4.0 ~ 10.0 meters, and top constructional surface is determined according to actual conditions.
As Fig. 2, with the burnt stacking volume of common petroleum for circular cone calculates its volume, the maximum angle of rest (repose) θ of the burnt stacking method circular cone of common petroleum
1be no more than 45 °, get θ
1be 45 °, floor space diameter D is generally at about 35 meters, and its volume computing formula is: V=π R
2h/3,
Wherein R is bottom surface radius, is 35/2 meter,
H=tg45 ° * 35/2 meter,
Then V1=5612m
3.
As Fig. 3, the round platform piled up with the present invention calculates volume, can allow angle of rest (repose) θ
2reach 50 ° to 75 °, store up the general height of bottom-to-top-height and be no more than 10 meters, floor space diameter D generally at about 35 meters, with angle of rest (repose) θ
2be 50 ° of calculating, its volume computing formula is: V=π h (R
2+ Rr+r
2)/3,
Wherein h is for storing up bottom-to-top-height, gets 10 meters, h
1for the height of compacting each time,
R is basal diameter=35/2 meter,
R is upper bottom surface diameter, and computing formula is (R-2 × h/tg50 °)/2=9.1 rice,
Then V2=5742m
3.
Bring the bulk density 0.76 ton/m of conventional method of piling into
3, new mode bulk density 0.86 ton/m
3, then in same accumulation place, the petroleum coke amount adopting distinct methods to pile up is:
M1=V1 × ρ 1=5612 × 0.76=4265 ton,
M2=V2 × ρ 2=5742 × 0.86=4938 ton,
Take new mode as seen, the petroleum coke accumulating amount of 15.78% can be improved.
If improve it again to pile up angle, then accumulating amount will be larger.
Compared with storing up driving surface with traditional taper shape, stack region and stacked arrangement by again planning, make it more scientific and reasonable, storing up efficiency can improve more than 20%; Petroleum coke is large owing to having the mutual gap of certain granularity, and not of uniform size, and therefore bulk density is less, and general deadweight is stacked petroleum coke bulk density and only had 0.76 ton/m
3, space hold amount is large, and space availability ratio is lower; If do not take actv. means and measure, the stacking effect of petroleum coke will be had a strong impact on; After compacting layer by layer, the petroleum coke of different-grain diameter can interpenetrate, and the bulk density of petroleum coke there occurs great changes, and bulk density is by original 0.76 ton/m
3be increased to 0.86 ton/m
3, bulk density adds nearly 12%; After have employed trapezoidal driving surface stacking petroleum coke, petroleum coke angle of rest (repose) have also been obtained increase, and under the operating mode of equal height, top is being not a line, but a plane, and stack in strict accordance with stacking height, trend and the order designed; Store up statistics by petroleum coke material object, storing up quantity can increase nearly 20%, achieves more satisfactory to store up effect, compensate for indoor coal storage yard because storing up the little storage in space coal, storing the deficiency of burnt ability.
Proved by production practice, in actual production, the petroleum coke stacked according to the present invention's way of storing up and feed coal can meet company's production requirement completely.Like this, not only save stacking place, controlled piling height, improve the degree of utilization of factory building and facility simultaneously, save investment; Also prevent the petroleum coke natural layering phenomenon that petroleum coke occurs in the process of storing up preferably, after stacking process middle level lamination is real, the petroleum coke of different-grain diameter can interpenetrate, bulk density is effectively increased, ensure that the physical property of petroleum coke is more stable, be convenient to the stable of production and have laid a good foundation.
