吕家坨洗煤厂密控系统改造分析

Analysis of the Reform of the Dense Control System of Lvjiatuo Coal Washing Plant

目前的洗煤工艺中对合格介质液密度的配比十分重视,可以说它是左右产品指标的一个至关重要的因素,所以各洗煤厂对密度控制系统的精确度和可操控性要求比较高。论文论述并分析了吕家坨矿洗煤厂密度控制系统的运行状况和存在的问题,针对问题提出了合理可行的改造方案,同时根据相应的改造方案对重要设备提出技术要求。

The current coal washing technology pays much attention to the proportion of the qualified medium liquid density. It can be said that it is a crucial factor controlling the products index, therefore, each coal washing plant has higher requirement on the accuracy and controllability of the density control system. This paper discusses and analyzes the operation status and existing problems of density control system of Lvjiatuo Coal Preparation Plant, and puts forward a reasonable and feasible reform plan for the problems, meanwhile, puts forward the technical requirements for important equipment according to the corresponding reform plan.
