Abstract

The invention provides a draught fan online monitoring system and method. The system comprises a temperature sensor, a negative pressure sensor, an electric power meter device, an industrial personal computer, a displayer and a database server. The temperature sensor and the negative pressure sensor are arranged on an inlet of a draught fan. Measured data can be used for calculating energy consumption of the draught fan. The energy consumption of the inlet condition of the draught fan is considered more accurately compared with the prior art. When the system is used for energy consumption measurement before and after energy-saving transformation and energy-saving condition calculation, calculation results are more accurate. The industrial personal computer and the displayer are adopted for centralized processing and monitoring of the data, the draught fan can be accurately monitored in real time, and therefore on the basis that the accurate data can be acquired, an operator can find and process deviation correspondingly in time when actual data deviate greatly.

Description

Technical field [0001] The invention relates to fan technology in metallurgical production processes, in particular to a more accurate online monitoring system and monitoring method for fan energy saving based on energy saving transformation. Background technique [0002] Fans are very important equipment in the metallurgical production process. They have a wide range of use, large quantities, and high energy consumption. They are used in ironmaking, coking, steelmaking, steel rolling, chemical and power plants and other areas, and their power consumption accounts for Baoshan points. About 40% of the company's total power consumption. As the power of motors such as dust removal fans, induced draft fans, and blowers in the metallurgical industry are generally large, the energy savings can be considerable, and fan energy-saving renovation projects have become an important business segment of energy-saving and environmental protection companies. [0003] Energy-saving transformation ...
