Self-balanced byproduct blast furnace gas dispatching system in iron and steel industry and method for predicting yield and consumption

Abstract

The invention discloses a self-balanced byproduct blast furnace gas dispatching system in the iron and steel industry and a method for predicting a yield and consumption. The self-balanced byproduct blast furnace gas dispatching system comprises a data acquisition subsystem, a blast furnace gas prediction subsystem and a yield-consumption-balanced blast furnace gas dispatching subsystem. The data acquisition subsystem is used for acquiring real-time production data of blast furnace gas, required prediction parameters, production planning data and the like, and the required prediction parameters, the production planning data and the like are used as original data; the blast furnace gas prediction subsystem is used for creating a corresponding prediction model and predicting the yield and the consumption of the blast furnace gas according to the collected original data; the yield-consumption-balanced blast furnace gas dispatching subsystem is used for judging a supply and demand balance condition of a gas quantity according to the yield and the consumption at a future moment and the original gas storage quantity, and producing a balanced dispatching scheme, and the yield and the consumption at the future moment are predicted by the gas prediction subsystem. The self-balanced byproduct blast furnace gas dispatching system and the method have the advantage that the self-balanced byproduct blast furnace gas dispatching system and the method are beneficial to improving the adjustment level of a byproduct blast furnace gas system in the steel and iron industry, improving the blast furnace gas yield and consumption prediction accuracy and dispatching the blast furnace gas in a balanced manner.

Description

technical field [0001] The invention belongs to the field of gas dispatching in the iron and steel industry, and in particular relates to a self-balancing dispatching system and a method for predicting production and consumption of by-product blast furnace gas in the iron and steel industry. Background technique [0002] With the rapid development of the national economy, my country's demand for steel is on the rise. Although my country's steel production ranks first in the world at present, after facing the international market, steel companies not only compete in production, but also steel quality, variety and production cost have become important factors affecting competition. As far as my country's current national conditions are concerned, energy costs are one of the main factors affecting steel production costs. The reason for the high production costs of most steel companies is directly related to low energy utilization and high waste. The by-product gas is a high-qu...
