尾矿输送临界流速尾矿输送临界流速critical velocity of the flow of tailings slurry welkuang shusong}inJ!e}一usu尾矿输送临界流速(critieal veloeity of theflow of tailings slurry)尾矿浆体由一种流动形态向另一种流动形态过渡的界限流速。临界流速对于尾矿水力输送中输送流速的确定有重要的作用。输送流速低于临界流速,易导致尾矿颗粒淤积甚至堵塞管、槽;过高于临界流速,则输送动力消耗大,管、槽壁的磨损加剧。 尾矿浆体多属沉降性浆体。它在水平管、槽中流动时,随着流速的由高到低的变化,阶段性地呈现出伪均质流、悬浮非均质流、有滑动层的非均质流和有沉积层的非均质流四种形态。当浆体流速较高时,尾矿颗粒在断面上的分布基本均匀,呈现伪均质流形态。当浆体流速减低时,尾矿颗粒在断面上的分布开始不均匀,有明显的浓度梯度,呈现悬浮非均质流形态。当浆体流速进 1步减低时,部分较粗或较重的尾矿颗粒沉积到管、槽底部,并以滑动、滚动和跳跃的方式向前移动,呈现有滑动层的非均质流形态。而当浆体流速降低到一定程度,尾矿颗粒在管、槽底部形成时冲时淤的活动底床或稳定的固定底床,此时即呈现有沉积层的非均质流形态。般低浓度的尾矿浆体,其临界流速也可相应地分为均质的、悬浮的和淤积的三种。 均质临界流速为伪均质流与悬浮非均质流的界限流速。悬浮临界流速为悬浮非均质流与有滑动层非均质流的界限流速。淤积临界流速则为有滑动层非均质流与有沉积层非均质流的界限流速。在淤积临界流速下输送浆体,其水力坡度(见尾矿输送水力坡度)近于最小。 不同阶段的临界流速概念有助于揭示固液两相流的运动规律。但淤积临界流速的概念更具实用性,因此实际工作中把它简称为临界流速。临界流速的计算方法很多,常用的有杜兰德(R.Durand)、瓦斯普(E.J.wasp)、尤芬(八.r工.。巾。H)、克诺劳兹(B.c.K,,opo。)和柯别尔尼克(C .1’.Ko6叩阴K)等人的公式。但这些公式的使用都有其局限性和近似性。对于重要的工程,如长距离的大、中型的尾矿水力输送系统,必要时应通过试验确定临界流速,以确保可靠性和降低能耗。中国选矿厂的尾矿水力输送临界流速多采用克诺劳兹公式计算,其公式为: (z)当口‘镇0 .o7mm时 VI~o·2夕(1+3 .43c昌“SDF‘875) (2)当0 .07匕己p簇0.15mm时 V,一O·255月(1+2.4sC吕“33刀尸25)式中d。为尾矿加权平均粒径,mm;Vl为矿浆临界流速,m/s;D,为临界管径,m; Cd为矿浆质量稠度又100;召为尾矿密度修正系数,按下式计算:月一(几一l)/x.7;z‘为尾矿密度,g/em3。
