Real time monitoring and information management system of coal-firing units gas desulfurization

Abstract

The invention relates to a coal-fired unit flue gas desulfurization real-time monitoring and information management system, and comprises a field data acquisition layer, a communication network layer and a monitoring center layer. Through the digital management of the overall process of online data acquiring, conveying, processing, accounting, analyzing, releasing, sharing, etc. of a desulfurization system in a thermal power plant, by operating the general theory of statistics, and combining the professional knowledge of the process control, a boiler, the environmental protection, etc., the invention performs sample analyses to the datum of the commissioning ratio, the desulfurization efficiency, and the discharge concentration, etc. of the desulfurization system, and builds a set of online monitoring systems which are based on the Web structure and the real-time communication. The invention is applied to the thermal power plant desulfurization facility to operate and perform the effective and long-term management, can authentically and accurately reflect the integrated operation level of the desulfurization system of the coal-fired desulfurization unit, and provides a quantification scale for the desulfurization facility operating the monitoring and the checking.

Description

technical field [0001] The present invention relates to a monitoring and management system, in particular to a coal-fired unit flue gas desulfurization network real-time monitoring, which realizes the whole process of online data collection, transmission, processing, calculation, analysis, release and sharing of thermal power plant desulfurization system Real-time monitoring and information management system for flue gas desulfurization of coal-fired units with digital management. Background technique [0002] At present, the main ways to reduce sulfur dioxide emission in thermal power plants are: coal washing, clean coal combustion technology, burning low-sulfur coal and flue gas desulfurization. According to my country's national conditions, flue gas desulfurization is the main way to control sulfur dioxide emissions in thermal power plants. With the establishment of the national scientific outlook on development, the country's emphasis on environmental protection and the...

AI Technical Summary

Problems solved by technology

[0003] Due to the low level of localization of the desulfurization system, large project investment, and high operating costs, power plants are reluctant to carry out desulfurization transformation, bid at low prices, and even have desulfurization facilities and do not operate

According to investigations, although many coal-fired power plants in the province
