Cement production and optimization system

Abstract

The invention discloses a cement production and optimization system which comprises a safety module, an economics module and an on-line decision control module. The safety module is used for analyzing and judging whether the current operating parameters and cement production equipment work normally or not according to real-time data, historical data and simulated data of operation of the cement production equipment and predicting whether the operating parameters are normal after the current time; the economics module is used for calculating the overall energy consumption and distributed energy consumption of cement production and comparing energy consumption data with international and domestic standard energy consumption index data; the on-line decision control module is used for optimizing raw material proportion and cement proportion of cement production and performing optimal control on a raw material mill system, a coal mill machine, a decomposition furnace, a pre-heater and a cement mill system. The cement production and optimization system disclosed by the invention integrates the functions of real-time production detection, optimal control and real-time production management, provides on-line analysis and guide, and can improve the operating safety and economy of the equipment.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a cement production and optimization system. Background technique [0002] The production of cement usually uses limestone and clay as the main raw materials, which are crushed, batched, and ground to make raw meal, and then fed into the cement kiln to calcinate the clinker, and then add an appropriate amount of gypsum to the clinker (sometimes mixed with mixed materials or Admixture) is finely ground. [0003] like figure 1 As shown, the production of cement can generally be divided into three processes: raw meal preparation, clinker firing and cement production. Among them, raw meal preparation is divided into dry method and wet method. The dry method generally adopts a closed-circuit operating system, namely After the raw materials are finely ground by the mill, they enter the powder classifier for sorting, and the coarse powder flows back into the mill for further...
