-型灰分仪在马脊梁选煤厂的应用 -

鉴于传统灼烧测灰法耗费时间长,存在较大滞后性,不能及时指导生产等缺点,提出了引进在线灰分仪的必要性。介绍了在线灰分仪的工作原理。通过在线灰分仪在马脊梁选煤厂的应用实践,说明在线灰分仪具有动态反应煤流灰分、有利于指导生产,实现自动检验、不需人工干预,检测结果准确、有利于质量控制,界面简单、操作灵活等优点。最后指出了日常的维护管理是保证灰分仪正常工作的关键,可通过定期进行输送带参数校验,经常监测、调整稳峰器监测点的电位,定期对现场的C型架和动力箱进行除尘擦拭,保证系统灵活可靠,做好比对,定期观察数据等工作,确保灰分仪检测结果的准确性。在线灰分仪的使用稳定了产品质量,提高了商品煤的综合回收率,增强了"大洗末"商品煤的竞争力。 There are some defects in traditional ignition test such as long test time,much more hysteretic,which lead to faulty production.In order to resolve those problems,online ash monitor is introduced as well as its working principle.The practical application of this kind of ash monitor in Majiliang coal preparation plant shows that it could reflect dynamically and automatically the ash.Its operator interfaces is simple and readily operation,the detection results are accurate,which is benefit for coal quality control.The analysis indicates that daily maintenance management determines the working conditions of monitor.The accuracy can be guaranteed by verifying belts parameters at regular intervals,monitoring and adjusting regularly electric potential of voltage stabilizer observation points,dedusting C type frame and power supply box,observing regularly datas and the like.The application of online ash monitor stabilizes the coal quality,improves merchantable coal's comprehensive recovery,enhances competitiveness of commercial coal
