Jinan Steel successfully developed automatic control system for oxygen generator

Jinan Iron and Steel Group Corporation regards the improvement of independent innovation capability as an important link to improve the core competitiveness of enterprises. Recently, the technicians of the Jinan Iron and Steel Automation Department independently developed the automatic oxygen generator automatic control system, which provided a powerful technical guarantee for the stable operation of the air separation unit of Jinan Iron and Steel Group, increasing the gas extraction rate and economic benefits, and reducing the difficulty and strength of production operations.

The automatic control system of the oxygen generator adopts DCS distributed control, and uses the automatic control technology, computer technology and network technology to build a management control network with centralized control, process production monitoring and production scheduling, which realizes real-time display of production data. , control and historical trend records, operation records, fault analysis and other functions.

It is understood that the automatic control system has reached the domestic advanced level, especially as the core control part of the entire control system, the air compressor anti-surge control technology is one step ahead. The so-called air compressor surge is when the air compressor is abnormal, the outlet pressure is getting higher and higher, and the flow is getting less and less. When this situation develops to a certain extent, the unit will produce severe vibration.

Surge has a serious destructive effect on the air compressor, and the operation of the unit to avoid this condition by adjusting the flow and pressure is anti-surge control. The technicians of Jinan Iron and Steel Automation Department combined with the actual situation of the production site, applied the four-wire control technology of response line, anti-surge line, surge line and safety line in the air compressor anti-surge control system, corresponding to different flow and outlet pressure. The ratio relationship between the two uses advanced techniques such as gradient control, asymmetric slope output, and automatic anti-surge curve compensation, so that the entire control system has a fast response speed, stable operation, and good anti-surge effect.
