Blast furnace burden distribution intelligent monitoring system and adjusting method

Abstract

The invention discloses a blast furnace burden distribution intelligent monitoring system and an adjusting method. The blast furnace burden distribution intelligent monitoring system is characterizedin that a communication server is used for transmitting setting parameters and real time data of a Programmable Logic Controller (PLC) of a system under a trough of a blast furnace, a PLC of a furnacetop burden distribution system and a PLC of a blast furnace body to a data acquisition server; and a function server is used for processing and modeling the data of the data acquisition server, establishing a burden distribution process monitoring module and a burden distribution result monitoring module and passing back results to each client through a browser / server framework. An operator optimizes the time sequence of burden distribution and adjusts the parameters of burden distribution through the burden distribution process monitoring module and the burden distribution result monitoringmodule on each client, so that the accurate control over the burden distribution is realized; and the design and optimization of burden distribution parameters are carried out by using the off-line function of the burden distribution result monitoring module, so that the airflow stability of the burden distribution process is ensured, the reasonable distribution of airflow is realized, and the optimized parameters are used for the operation control of the practical blast furnace. The system realizes the whole internet availability after being installed at one place, and is convenient to use and simple to maintain.

Description

technical field [0001] The invention belongs to the technical field of process control in the metallurgical industry, in particular to an intelligent monitoring system and adjustment method for blast furnace material distribution. Background technique [0002] Blast furnace roof distribution is very important to the stability and economy of blast furnace operation, but due to equipment limitations, the distribution of material level during blast furnace production cannot be obtained. People predict the distribution of the material surface after the cloth is finished by establishing mathematical modeling, such as US Patent US. CN104694680A considers the impact of changes in blast furnace operating parameters on material surface accumulation during actual production operations. They only stop at the simulation of the ore-coke ratio distribution, but in actual production, it is found that the size of the central non-ore area and the thickness of the local minimum coke window h...

AI Technical Summary

Problems solved by technology

They only stop at the simulation of the ore-coke ratio distribution, but in actual production, it is found that the size of the central non-ore area and the thickness of the local minimum coke window have a great influence on the operation of the blast furnace, and these models cannot simulate the material layer falling from the furnace throat Changes in the process of reaching the tuyere

In addition, the existing technology cannot reflect the influence of the distribution of the furnace top material surface on the airflow fluctuation during the blast furnace material distribution process, and the error generated in the material distribution process for the optimization of the material distribution parameters

At present, there is a lack of a software that monitors the furnace top distribution process, distribution results and airflow throughout the process to guide the optimization of distribution parameters
