选煤厂管道设计与改进

Design and improvement of pipework in coal preparation plant

管道在选煤厂应用广泛,其在物料转载与输送、设备连接、工艺流程转换中起着至关重要的作用,管道设计是否合理直接关系到选煤厂能否正常运行。在对管道设计规则和常用材料分析的基础上,结合管道设计经验和现场使用情况对其设计进行技术改进,目的是为选煤厂管道的设计、优化提供一定借鉴。

Piping lines are widely used in coal preparation plants and play an important role in transfer and conveyance of materials, connection of process equipment and switching-over of processes. Whether the piping lines are rationally designed or not exerts a direct bearing on the normal operation of a coal preparation plant. Work is made in the paper on technical renovation of the piping lines based on the code for design of piping lines, the result of analysis of pipe materials in common use, the experience gained in piping design, and the result of application of the piping lines under practical site conditions, so as to provide certain reference for design and optimization of pipework in coal preparation plants.
