It is hard to achieve the automated control and optimized control of rotary kiln because of their multi-factors, close coupling, non-linear and serious interference of key parameters.
It is much meaningful for the improvement of the quality of clinkers and the using rate of rotary equipment, and the reduction of energy consumption to research the intelligent optimized controlling technology and intelligent optimized controlling platform.
The intelligent optimal control software platform of rotary kiln is a kind of application software to control and monitor rotary automation.
The technology of foreign control system software is non-transparent.
Although their control on basal loop is stable, intelligent control is rarely mentioned.
Because of the development of domestic software platform starts later than abroad, their structure of the platform isn’t strong enough and reuse rate of code isn’t high enough.
Therefore, the research on intelligent optimal control software platform with modular structure and the function of developing intelligent optimal control strategies is necessary.
The detailed works have been summarized as follows:
1. The whole structure and function of the platform are designed. The structure of the platform is established and combined with modules organically. We organize the structure of intelligent optimal control software platform with more clarity and reusability.
2. The platform is divided into four modules: plot module for human machine interaction of rotary kiln, database module for the management of control volume and detection volume, communicate module for data transmission with lower computer, strategy module for development of intelligent optimal control. In order to achieve ease of use and scalability, powerful base classes are designed and implemented by the object-oriented language.
3. To the strategy module, a method is proposed based on the design of flow chart, generating script dynamically, explaining and implementing by compiler of the system. This method can reduce the volume of developers programming, so they can focus on the development of intelligent control algorithm.
The active lime is the
basic raw material for steel and ore industry. it can shorten the
calcining time, improve purity and recycling rate of liquid steel,
reduce the consumption of quartz and fluorite and improve the service
life of kiln bucket, besides, it can also be used in the process of
steel perfection.
The rotary kiln, as one of the major calcining equipments, is widely used in our country, and it has wide materials shape, size adaptability and good inner mixture. http://sandmaker.wordpress.com/
