Real-time control method for coal gas dynamic balancing in steel plants based on cabinet position prediction

Abstract

A cabinet-based prediction method for the real-time control of the gaskinetic equilibrium in the steel enterprise, relating to the real-time control technique for the kinetic equilibrium of the by-product gas in the steel enterprise; the utility model is used to solve the off-balance between the supply and demand of the gas system for a short period of time. As the detection technique and the control medium of the automatic gas system are perfected, the operator can fully control the operating condition of the gas system, including the main pipeline pressure, the flow, the user flow, the conveyer equipment and the storage facility. Meanwhile, the regression model is adopted to forecast the future developing trend of the gas system as per the real operation data and the estimation on the main performance currently. Furthermore, based on the balance-related experiences of the site operator, the system will dynamically give out the operating recommendation concerning the adjustable gas use volume or the calorific value in the blending station, so as to balance the gas use level rapidly and decrease the gas emission. Thus, the gas can be effectively used.

Description

Technical field: [0001] The present invention relates to a kind of automatic control technology, relates to the dynamic balance real-time control technology of iron and steel enterprise by-product gas (blast furnace gas, coke oven gas, converter gas), especially the steel enterprise gas dynamic balance real-time control method based on counter position prediction, In order to solve the problem of unbalanced gas system supply and demand caused by short-term reasons. Background technique: [0002] At present, the gas balance of iron and steel enterprises is in the offline stage. Most enterprises can formulate a gas balance plan in advance according to the monthly maintenance plan by technicians, notify the dispatcher, and then download it to each operation post for operation. As for the short-term gas imbalance caused by unplanned maintenance, due to the different management concepts of various enterprises, most of them use post operators----→ dispatchers to understand the sit...

AI Technical Summary

Problems solved by technology

As for the short-term gas imbalance caused by unplanned maintenance, due to the different management concepts of various enterprises, most of them use post operators----→ dispatchers to understand the situation of each post----→telephone notification operation--- -→Reflecting the situation after dispatching personnel deployment, so repeated until the balance of gas supply and use, the lagging gap will easily cause pressure fluctuations in the gas pipeline network, which will bring hidden dangers to production; due to the different abilities of dispatching personnel and different balancing methods, the utilization rate of gas will greatly reduce

[0003] At the same time, due to the differences in the detection level, control and regulation methods of the automation systems of various enterprises, the dispatchers have no means of quantitative balance when performing gas balance, and mainly rely on the dispatcher's experience and experimental methods. If the dispatcher is rich, the gas system will return to normal operation quickly; and if the dispatcher is a new employee, it may take a long time for the gas system to return to normal and increase the probability of gas release
