3 100000 万NM /a 煤气发生炉冷煤气站的初步设计 摘 要 煤炭被人们誉为黑色的金子，工业的食粮，它是十八世纪以来人 类世界使用的主要能源之一。煤气化技术是煤炭清洁高效转化的核心 技术。它是以煤或焦煤为原料，以氧气（空气，富氧或纯氧）、水蒸 气或氢气等作气化剂，在高温条件下通过化学反应将煤或焦煤中的可 燃部分转化为气体燃料的过程。作为洁净煤技术的一种，在我国煤气 化技术有着重要的存在和发展的价值。本设计综述了相关文献，按照 任务书的要求，结合原料煤的来源、煤气的用途、供气压力要求等因 素，对比了各种不同类型的气化工艺流程，分析了热、冷煤气站之间 以及冷煤气站中相关的工艺流程的特点。重点论述和探讨了无烟煤冷 煤气站的建立，从而对从原料煤入炉到净煤气入柜为止的初步设计工 艺流程进行了设定。设定的流程为：煤气发生炉→旋风分离器→废热 锅炉→单竖管→半净煤气总管→隔离水封→洗涤塔→ 电除尘→净煤 气总管→排送机→捕滴器→总管。在选定的工艺流程的基础上，通过 对物料及热量平衡、设备选型的计算，确定了相关的工艺参数。并且 绘制了带控制点工艺流程图、煤气站设备平面布置图和煤气站设备立 面布置图。 关键词：煤炭，煤气化，冷煤气站，初步设计 I PRELIMINARY DESIGN OF COLD GAS STATION 3 ABOUT THE GAS GENERATOR OF 1 BILLION NM /A ABSTRACT Coal is known as black gold, industrial food, it has been one of the main energy since eighteenth century the human uses. Coal gasification technology is the clean efficient conversion of the coal technology. Based on coal or coke as the raw material, and oxygen (air, oxygen or pure oxygen), steam or hydrogen as a gasifying agent, it is a process of transforming combustible portion in the coal or coke into the fuel gas at high temperature through a chemical reaction. As one of the clean coal technologies, coal gasification technology has the very important value of existence and development in our country. According to read a lot about the task and issue in accordance with the design of the graduation requirements of the book, and based on the requirements of raw materials, the coal gas source, the purpose, gas pressure, the different types of gasification process are compared and the properties of hot/co
