【摘要】：钢铁产业作为我国国民经济的一项重要基础产业,为国家经济快速健康发展做出了无法取代的贡献,与此同时,钢铁产业也给国家带来了高能耗和重污染,如何节能减排,一直是钢铁企业重要的研究课题。钢铁冶炼过程所需的技术气体如氧、氮以及氩等气体是钢铁企业重要的二次能源,对钢铁企业的顺利运行起着关键的作用,但是与发达国家相比,我国的钢铁企业仍然存在着氧气放散量大、生产成本高、利用率低的问题。因此,对如何科学组织氧气生产供应,优化调度系统生产组织方案,提高氧气系统的综合利用率,降低制氧工序能耗成本,为企业带来最大的效益,是值得深入研究的课题。本论文的主要内容如下：(1)阐述了课题的研究背景和意义,分析了目前钢铁企业氧气系统存在的问题及研究现状。(2)以国内某知名大型钢铁企业为研究背景,详细介绍了制氧系统的工艺流程,对该企业的氧气系统现有的运行状况及能耗特点进行了深入分析,挖掘出生产组织方案的不匹配是影响空分制氧工序能耗的关键因素。考虑制氧系统的工艺流程及物理约束等约束条件,以最优化方法为理论基础,建立制氧系统的优化调度模型,合理安排技术气体的生产过程,实现节能减耗的目标。(3)建立的氧气系统优化模型以氧气放散率最低和经济效益最大为优化目标函数,以制氧系统中的工艺流程等为约束条件。结合改进的多目标粒子群算法,对模型进行求解,将优化后的结果与该企业现有的生产状况作对比分析,可知本文优化方法有效性和可行性。(4)以能源管理系统为基础,以数据库服务器和Web服务器为支撑,以优化调度模型和本文所提出的优化算法为核心控制思想,通过Citect组态软件和Microsoft visual studio平台开发先进调度管理系统。该系统已在企业中得到应用,取得了较好的效果,为调度系统优化研究成果在空分制氧领域的应用做出了有益尝试。
[Abstract]:As an important basic industry of our national economy, iron and steel industry has made an irreplaceable contribution to the rapid and healthy development of national economy. At the same time, iron and steel industry has also brought high energy consumption and heavy pollution to the country, how to save energy and reduce emissions. It has always been an important research topic for iron and steel enterprises. The technical gases such as oxygen, nitrogen and argon, which are needed in the process of iron and steel smelting, are important secondary energy for iron and steel enterprises, and play a key role in the smooth operation of iron and steel enterprises, but compared with the developed countries, Iron and steel enterprises in our country still have the problems of high oxygen emission, high production cost and low utilization ratio. Therefore, how to scientifically organize the oxygen production supply, optimize the production organization scheme of the dispatching system, improve the comprehensive utilization ratio of the oxygen system, and reduce the cost of energy consumption in the oxygen production process, which bring the greatest benefit to the enterprise, is a subject worthy of further study. The main contents of this paper are as follows: (1) the research background and significance of the project are described, and the existing problems and research status of oxygen system in iron and steel enterprises are analyzed. (2) A well-known iron and steel enterprise in China is taken as the research background. The process flow of oxygen production system is introduced in detail. The operating status and energy consumption characteristics of oxygen system in this enterprise are deeply analyzed. The mismatch of production organization scheme is found to be the key factor affecting the energy consumption of air separation oxygen production process. Considering the process flow and physical constraints of the oxygen production system, based on the optimization method, the optimal scheduling model of the oxygen production system is established, and the production process of the technical gas is reasonably arranged. (3) the oxygen system optimization model takes the lowest oxygen release rate and the maximum economic benefit as the optimization objective function, and takes the process flow in the oxygen production system as the constraint condition. Combined with the improved multi-objective particle swarm optimization algorithm, the model is solved, and the optimized results are compared with the existing production situation of the enterprise. The results show that the optimization method is effective and feasible. (4) based on the energy management system, Based on the database server and Web server, taking the optimal scheduling model and the optimization algorithm proposed in this paper as the core control idea, the advanced scheduling management system is developed through the Citect configuration software and Microsoft visual studio platform. The system has been applied in enterprises and has achieved good results. It has made a beneficial attempt for the application of the research results of scheduling system optimization in the field of air separation oxygen production.
