Semi-physical simulation platform and simulation method thereof used in cement clinker calcining process

Abstract

The invention relates to a semi-physical simulation platform used in a cement clinker calcining process. According to the semi-physical simulation platform used in the cement clinker calcining process, a software simulation device, a signal conversion device, a control system and a monitoring device are connected in sequence. A simulation method of the semi-physical simulation platform comprises the steps that procedure parameters are input into a cement clinker calcining process dynamic model established by the monitoring device and sent to the control system; the procedure parameters are output by the control system to the signal conversion device, data conversion is carried out on the procedure parameters by the signal conversion device, and the procedure parameters are then output to a memory of the software simulation device to be stored; the software simulation device acquires virtual working condition parameters; the virtual working condition parameters output by the software simulation device are fed back to the control system by the signal conversion device; the virtual working condition parameters of the control system are received by the monitoring device and then are displayed through a human-computer interaction interface in an imaging mode. According to the modeling of the semi-physical simulation platform and the simulation method thereof used in the cement clinker calcining process, the dynamic variation rule of in-kiln gas-solid interphase energy and mass exchange is described from the view of mechanisms based on basic principles of mass conservation, energy conservation and macroscopic reaction kenitics.

Description

technical field [0001] The invention relates to the technical field of cement clinker calcination, in particular to a dynamic modeling and semi-physical simulation platform of the cement calcination process. Background technique [0002] The cement clinker calcination process has the characteristics of high nonlinearity, strong coupling and time delay. Based on the consideration of operation continuity and safety, it is difficult to realize on-site trials for new employee training, new process design and risk assessment, and feasibility assessment of various alternative schemes. Even if there are conditions to conduct experimental research, it will cause a lot of waste of resources. In addition, the clinker calcination process is carried out in a continuously rotating rotary kiln, the internal gas temperature is as high as thousands of degrees, accompanied by a lot of dust, many key parameters cannot be directly measured, resulting in clinker quality control can only rely o...
