Furnace group energy consumption system and method in fused magnesia smelting process

Abstract

The invention discloses a furnace group energy consumption system and a method in a fused magnesia smelting process and belongs to the field of electric furnace energy consumption management. The furnace group energy consumption system comprises a database server, an application server, a client and a data collecting programmable logic controller (PLC). The application server comprises a data collecting module, an energy consumption index decomposition module, an energy consumption operation monitoring module and an energy consumption statistic analysis module. A general energy consumption index of the whole factory in the very day is calculated based on a production index issued by a superior, a historical statistic unit energy consumption value and an energy saving index and decomposed into energy consumption index values in all time intervals of all fused magnesia furnaces in a detailed mode. Energy consumption data of all the electric furnaces are collected in real time, and when an actual value exceeds the index value, warning information is sent to a manager so as to aid the manager to manage fused magnesia furnace energy consumption. In addition, electricity utilization links of empty burning, irregular operation and the like can be found for the manager through the analysis of the real-time energy consumption data, and the manager can be aided to perform energy consumption supervision and management.

Description

Technical field [0001] The invention belongs to the field of electric furnace energy consumption management, and specifically relates to a group furnace energy consumption alarm system and method in an electric fused magnesia smelting process. Background technique [0002] my country is the world's largest producer of fused magnesia, but the electricity consumption efficiency of fused magnesia is far behind Russia and other countries. At present, the management of electrical energy consumption in the production of fused magnesia is mainly carried out manually. The manager determines the number of furnaces that are started on the day by the number of products to be produced every day, and then the operator himself controls the smelting of each furnace based on experience process. After the smelting is completed, the electric energy, output and product quality consumed by each furnace in this production can be obtained, and then management and optimization can be carried out based...
