Automatic heat regulation and control method and device of grinding system of vertical mill

Abstract

The embodiment of the invention provides an automatic heat regulation and control method of a grinding system of a vertical mill. The automatic heat regulation and control method includes the steps ofobtaining state data in operation of the grinding system of the vertical mill, predicting the state data through a Gaussian process regression model on the basis of the state data to obtain a prediction result, obtaining a corresponding heat regulation measure and a regulation moment corresponding to the heat regulation measure on the basis of the prediction result, and performing heat regulationand control on the grinding system of the vertical mill on the basis of the heat regulation measure and the regulation moment. Meanwhile, the invention further provides a corresponding automatic heatregulation and control device of the grinding system of the vertical mill. By means of the automatic heat regulation and control method and device, the automation and intelligence of heat regulationand control in the grinding system of the vertical mill are improved.

Description

technical field [0001] The invention relates to the field of heat control, in particular to a method for automatic control of heat in a vertical mill grinding system, an automatic control device for heat in a vertical mill grinding system, and a corresponding medium. Background technique [0002] Vertical mill grinding is a dry material vertical mill grinding system, which integrates the functions of material grinding, drying and grading, and is mainly used for the grinding production of limestone mixture, slag and steel slag. [0003] The grinding system of the vertical mill has a large processing capacity, and the raw materials are stored in the open air. If the material is too dry, the material layer in the grinding area will be unstable, and the equipment will vibrate greatly, which will affect the safety of the equipment. In order to maintain the stability of the material layer during the grinding process, it is necessary to spray water on the material. However, many pr...

Problems solved by technology

[0003] The grinding system of the vertical mill has a large processing capacity, and the raw materials are stored in the open air. If the material is too dry, the material layer in the grinding area will be unstable, and the equipment will vibrate greatly, which will affect the safety of the equipment. In order to maintain the stability of the material layer during the grinding process, it is necessary to spray water on the material. However, many production lines have not been equipped with electric water spray control, and the ground materials are in powder form. In order to collect, store, and transport, they need to be in a dry state. Therefore, during the processing process, the ground materials are dried by hot air circulation, and The formed gas and solid fluid are transported to the collection system through classification

If too much heat is supplied, the material will be too dry, and the material layer in the grinding area will be unstable, resulting in large vibrations, resulting in shutdown, waste of heat, and increased emissions

[0004] The material will also be affected by weather and seasons. The moisture content of the material entering the vertical mill grinding system is uncontrollable. At the same time, the vertical mill grinding system is closed, the temperature change has a lag, and the heat supply regulation is often not timely enough. During the production process, the material Moisture content fluctuations will destroy the dynamic balance of the system, and will also affect technical indicators such as output, power consumption, and product quality.
