Method for dividing and identifying typical working conditions of cement grate cooler

Abstract

The invention discloses a method for dividing and identifying typical working conditions of a cement grate cooler. The method comprises the following steps: screening characteristic parameters capable of representing the working condition of the grate cooler; carrying out dimension reduction processing on the characteristic parameters; dividing the characteristic parameters subjected to dimension reduction into typical working conditions of the grate cooler by using an SAGA-FCM algorithm; and designing a typical working condition recognizer, and recognizing the typical working condition of the grate cooler. According to the method, on the basis of the combination of the local preserving projection technology and the SAGA-FCM algorithm, the typical working conditions of the grate cooler are divided and recognized, and the difference of knowledge and experience between different operation engineers is eliminated; the problem that the clinker cooling and heat recovery effects are affected due to the fact that the technical levels of operation engineers are different and operation behaviors are easily dominated by subjective willingness and the working state of the cement grate cooler is judged inaccurately is effectively solved.

Description

technical field [0001] The invention relates to a method for classifying and identifying typical working conditions of a cement grate cooler, belonging to the technical field of cement production control. Background technique [0002] The cement industry is one of the pillar industries of my country's national economy, and the cement grate cooler has become the main equipment for cooling cement clinker in modern cement production. It has become an important development direction of the cement industry to build intelligent cement production plants and improve the high degree of automation, integration and greening of cement enterprises. [0003] In the cement production process, the grate cooler is the key equipment for cooling high-temperature clinker and recovering heat. Its stable and efficient operation is of great significance for cement enterprises to improve clinker quality, reduce consumption and save energy. [0004] However, due to frequent changes in the working c...

Problems solved by technology

[0004] However, due to frequent changes in the working conditions of the grate cooler, the optimal control of the grate cooler mainly relies on the knowledge and experience of the operating engineer, and due to the differences in the technical level of the operating engineers and the operation behavior is easily dominated by subjective wishes, the current working conditions of the grate cooler The condition judgment is not accurate, which will affect the cooling of cement clinker and the recovery of heat
