Water quenching treatment system and method for RKEF ore heat slag of laterite-nickel ore
The invention discloses a laterite-nickel ore RKEF ore heat slag water quenching treatment system and method. The system comprises a slag discharging chute (1) located at a slag discharging opening of the submerged arc furnace, a slag flushing nozzle (2) located below the slag discharging chute and a water discharging opening (3). The length of the deslagging chute is 0.5-10 meters, the width of the deslagging chute is 0.5-2 meters, and the height of the deslagging chute from the ground is 2-5 meters; and an included angle between the direction of the slag discharge chute and the direction of the slag flushing nozzle is 1-10 degrees. The water quenching treatment process by using the system comprises the following steps: the ore heat slag enters the slag discharge chute from the slag discharge port, the slag flushing nozzle discharges water to carry out water quenching treatment, the slag is crushed into slag particles after water quenching is finished, the slag particles and redundant water are settled to the ground, the water is collected through the water discharge port to be recycled, and the slag particles are collected and transported outwards. According to the system, on the basis of the synergistic effect of all the components, the utilization rate of cooling water is increased, meanwhile, the ore-smelting furnace slag is crushed, the steps of post-treatment and the like on slag particles are not needed, and the large-scale industrial production requirement can be met.
本发明公开了一种红土镍矿RKEF矿热炉渣水淬处理系统及方法。该系统包括位于矿热炉排渣口的出渣溜槽(1)、位于出渣溜槽下方的冲渣喷嘴(2)和排水口(3)；所述出渣溜槽长度为0.5～10米，宽度为0.5～2米，距离地面高度为2～5米；所述的出渣溜槽方向与冲渣喷嘴方向的夹角为1～10°。利用该系统进行水淬处理的过程为：矿热炉渣自排渣口进入出渣溜槽，冲渣喷嘴出水进行水淬处理，水淬结束后炉渣破碎为渣粒与多余水分沉降至地面，水分通过排水口收集进行循环使用，渣粒收集外运。该系统基于各组件之间的协同作用，在提高冷却水的利用率的同时，还对矿热炉渣进行破碎，无需对渣粒进行后处理等步骤，可满足大规模工业化生产需求。
