Cement digital management and control system

Abstract

The invention discloses a cement digital management and control system which comprises a simulate sub system, a production and optimization sub system and a data base. The simulate sub system is connected with the production and optimization sub system. The data base is respectively connected with the simulate sub system and the production and optimization sub system. The simulate sub system is used for performing simulating calculation to cement production. The production and optimization sub system is used for analyzing and judging whether current operating parameters and operation of cement production devices are normal, forecasting whether the operation parameters are normal after current time and controlling the cement production in an optimized mode. The data base is used for storing historic operation parameters and the current operation parameters, the range of the operation parameters and corresponding relationship between the operation parameters and state of the devices. Online simulated analysis technology, historic data analysis technology and an advanced diagnosing and optimizing method are adopted as methods of a digital management and control system so that economical and safe operation of a cement factory is achieved.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a cement digital control 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] Such as 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 grinding...
