[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.
