为实现矿热炉节能降耗、稳定生产,以电石生产的物性参数、电极参数、实时生产参数为输入量,通过一系列的平衡计算及回归分析,建立了基于电石液产量的电石液排放管理模型,实时得出电石液产量、电石液发气量、预测电石液排放时间及吨电石耗电量等参数指标。通过采集与处理现场电石炉生产数据以及编程技术实现了该模型的在线计算,并成功应用在电石炉与主控室之间建立起一条电石生产预测的信息通道,实时反映电石生产状态。实践表明,优化电石液排放管理可适当提高电石液发气量,增加电石生产的生产效率,同时适当降低吨电石耗电量,达到高效、节能、降耗、稳定生产的目的。

In order to achieve submerged arc furnace energy-saving and stable production, the physical parameters, electrode parameters, real-time production parameters of calcium carbide production as input, through a series of equilib-rium calculations and regression analysis, based on production of calcium carbide, calcium carbide liquid emissions man-agement model is built, the real yields derived liquid calcium carbide, calcium carbide liquid gas evolution, the time pre-dicted and tons of calcium carbide power consumption etc. parameters are given. By collecting and processing data as well as on-site production of calcium carbide furnace programming technology online, the calculation of is realized, and successfully applied, the information channel between calcium carbide furnace and the main control room is established, which could forecast and reflect the real-time conditions of calcium carbide production status. Practice shows that the op-timal solution of calcium carbide calcium carbide emissions management may be appropriate to increase the liquid gas evolution, increasing the production of calcium carbide production efficiency, while appropriate to reduce the tons of cal-cium carbide power consumption, realizes the high efficiency, energy saving, stable production purposes.
