湿式球磨机钢球自动添加策略
|
摘要
现在火电厂中大多使用石灰石/石膏湿法进行烟气脱硫,很多电厂就会使用到石灰石湿式制浆系统,而其中湿式球磨机起着很重要的作用。在湿式球磨机工作过程中由于钢球的磨损会造成钢球数量减少,就目前来讲球磨机添加钢球主要通过人工凭借经验来添加,这样做费时费力且钢球减少会影响石灰石浆液的颗粒细度,这直接关系到脱硫的品质。本文则介绍一种基于专家系统的自动添加方式,通过检测一些相关参数来判断是否添加钢球,以及添加钢球的型号及数量。
At present, most of the thermal power plants use limestone/gypsum wet method for flue gas desulfurization. Many power plants use limestone wet pulping systems, and wet ball mills play an important role. In the working process of the wet ball mill, the number of steel balls is reduced due to the wear of the steel ball. At present, the addition of the steel ball to the ball mill is mainly added by manual experience, which is time consuming and laborious. And the reduction of the steel ball will affect the fineness of the limestone slurry, which is directly related to the quality of the desulfurization. This paper introduces an automatic addition method based on the expert system, by detecting some relevant parameters to determine whether to add steel balls, and to add the model and quantity of steel balls.
