介绍了钛白粉生产中酸解渣的产生和利用情况,目前对钛白生产过程中产生的酸解废渣进行固液分离主要采用传统的稀释法,该工艺存在钛液回收率偏低和产生大量洗水的缺点。叙述了应用过滤设备的新工艺情况,利用箱式压滤机分离钛白生产酸解过程中产生的酸性残渣,结果为:钛液的回收率达91.8%,较该装置上马前提高3.6%,结果表明该装置能较完全提取残渣中钛液,提高钛白收率,同时沉降底部残渣中的钛液经分离后不会被稀释,降低残渣的含水量,便于残渣综合利用。 相似文献

This work investigated the amounts of dust residual of a rectangular flat pleated filter for collecting corn straw particles during pulse cleaning and attempted to explore the causes of incomplete cleaning. In this study, dust residual, filter’s pressure drops and static peak pressures were obtained across flat pleated filter during the pulse cleaning. The optimum parameters were obtained that the pulse electromagnetic valve size was one inch, the pulse pressure was 0.2–0.3?MPa, and the filtration velocity was 0.6?m/min for the nozzle type with 7 holes with a diameter of 7?mm (7?×?Ф7?mm). Under this condition, the experimental results show that the dust residuals were 198.4 (64%), 52.7 (17%), 58.9 (19%)?g for initial collected dust residual 310?g at top, middle and bottom areas of the filter panel, respectively. The dust residuals were major on the top area of the filter panel, especially on the gap locations between the two-adjacent pulse airflows. Meanwhile, the more pulse interval or dust concentration was increased the dust residuals of the filter panel and the pressure drops of the filter were increased. Moreover, the static peak pressure distribution can give guidance to the dust residual distribution. 相似文献

在捷联惯导系统初始对准状态估值过程中,针对传统Kalman滤波器的实时性问题,提出了基于支持向量机(SVM)网络的滤波器。采用闭环Kalman滤波器的输入和输出数据作为训练样本对进行训练得到SVM模型。通过仿真实验对比表明,采用SVM网络滤波器的估计精度与采用闭环Kalman滤波器的相当,但估计速度比较快。 相似文献
