Abstract

The invention discloses a control method of alumina production. According to the method, a decentralised control system is used to carry out centralized control of the production process of each workshop. The decentralised control system comprises an information control center and central control rooms of each workshop. The information control center is provided with a host computer. Each central control room of the workshops is provided with a redundant data processor, a redundant data exchanger and a workshop monitoring terminal. The redundant data processor of each central control room of the workshops connects an annular fiber communication network through the redundant data exchanger of the central control room. The host computer comprises a plurality of monitors and a control terminal, and connects the annular fiber communication network through a network server. According to the method, the centralized control and centralized management of the data in the whole production process of alumina are realized, and safety production level and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of chemical production process control, in particular to an alumina production control method. Background technique [0002] High-alumina fly ash is a new type of fly ash that has emerged in recent years with the development of coal resources and the construction of thermal power plants in my country. Its alumina content is usually very high, which is equivalent to the low-grade bauxite in my country. Alumina content in ore. In recent years, with the increasing shortage of bauxite resources in my country, the use of high-alumina fly ash to produce alumina has attracted more and more attention. Extracting alumina from fly ash is a high value-added utilization of fly ash as a secondary resource. The research on useful resources such as aluminum is still in the stage of theoretical research. At present, the commonly used methods can be divided into acid method and alkali method. The acid method is more repres...
