Calcined coke quality impact analysis process control method

Abstract

The invention relates to a calcined coke quality influence analysis technology control method. PLC data from a calcination workshop is sent to a calcination workshop data analysis server through a workshop bus data conversion terminal, an offline measuring data acquisition terminal sends the acquired data to the calcination workshop data analysis server, green coke performance information in a raw material database server is sent to the calcination workshop data analysis server through a first workshop-grade data interaction platform middleware, the calcination workshop data analysis server sends a received data analysis result to a comprehensive control parameter influence analysis module, and the comprehensive control parameter influence analysis module performs calcined coke quality influence weight analysis on the analysis result, displays the analysis result on the calcination workshop data analysis server, and at the same time, sends an influence weight analysis result to a client server through a second workshop-grade data interaction platform middleware. The calcined coke quality influence analysis technology control method has the advantage of reducing the energy consumption of a production process and the operation cost.

Description

technical field [0001] The invention relates to a quality impact analysis process control method, in particular to a quality impact analysis process control method of calcined coke, a raw material for prebaked anode production. Background technique [0002] Calcined coke is the main raw material for the production of prebaked anodes for aluminum electrolysis, and its production quality directly determines the quality of prebaked anode carbon blocks and their specific performance on the electrolytic cell. Factors affecting the quality of calcined coke products include not only delayed petroleum coke calcination Process parameters such as negative pressure and temperature are controlled, and are directly related to raw material conditions such as delayed petroleum coke volatile content and trace element content. Since the current entire petroleum coke calcination production process control is mostly completed by technology and operator production experience, Therefore, once th...

[0002] Calcined coke is the main raw material for the production of prebaked anodes for aluminum electrolysis, and its production quality directly determines the quality of prebaked anode carbon blocks and their specific performance on the electrolytic cell. Factors affecting the quality of calcined coke products include not only delayed petroleum coke calcination Process parameters such as negative pressure and temperature are controlled, and are directly related to raw material conditions such as delayed petroleum coke volatile content and trace element content. Since the current entire petroleum coke calcination production process control is mostly completed by technology and operator production experience, Therefore, once the quality of calcined coke lumps fluctuates or unqualified products continue to appear, it is difficult for the existing process control methods and systems to find out the cause in time and make a quick response. The result not only affects the quality of calcined coke, but also directly increases the energy consumption of the process, affecting Whole anode production running cost
