Energy-saving type air compressor control system and method based on DCS comprehensive control

Abstract

The invention provides an energy-saving type air compressor control system and method based on DCS comprehensive control. The energy-saving type air compressor control system based on DCS comprehensive control comprises a compressor unit, an electric unit and a DCS control unit; the DCS control unit comprises a signal acquiring device set and a DCS controller; the signal acquiring device set is used for monitoring the running states of the electric unit and the compressor unit; and the electric unit controls starting, loading, unloading or stopping of the compressor unit according to an instruction emitted out of the DCS control unit. According to the energy-saving type air compressor control system based on DCS comprehensive control, the DCS controller is adopted for controlling the compressor unit in real time, so that running of the compressor unit is more reasonable, and the running energy consumption of the compressor unit can be lowered; and meanwhile, data scanned and obtained by the DCS controller can be stored into a DCS historical database, the historical work condition in any time period of the whole life period of equipment can be read back, and the fault analyzing andequipment optimizing requirement is fully met.

Description

technical field [0001] The invention relates to the field of air compressor control, in particular to an energy-saving air compressor control system and method based on DCS overall control. Background technique [0002] In recent years, the country has continuously increased the promotion of energy-saving products. As a product used in domestic mining, metallurgy, electric power, electronics, machinery manufacturing, medicine, food, textile light industry, and petrochemical industries, air compressors are energy-saving products. The development of technology is of great significance to the cause of energy conservation in our country. [0003] At present, the active air compressors in the industrial field mainly have the following main problems. First, the design of most air compressors is original, still based on single-chip microcomputer or early PLC, and the control strategy cannot be modified after packaging and locking; second, the process control is simple, the adjustm...

AI Technical Summary

Problems solved by technology

In the current sales market, volume flow ≥ 30m 3 Ordinary air compressors per min cost about 300,000-500,000 yuan. Combined with the design method of setting up 3 or more sets of air compressor stations generally in industrial enterprises, superimposed labor and material costs, a thorough energy-saving renovation of air compressor stations About 1.5 million yuan is needed, and the payback period of the energy-saving benefits generated by it is usually more than 10 years
