Online monitoring and management system for ultra low emission unit

Abstract

The invention discloses an online monitoring and management system for an ultra low emission unit, which comprises a data processing module, a technological process configuration processing module and an evaluation index online calculation module, wherein the data processing module is composed of a data acquisition module, a data compression transmission module and a data storage module; the technological process configuration processing module uses PI Processbook to carry out full replication on a field DCS monitoring scene, an SVG technology is used for carrying out processing and display on a monitoring platform, and full replication of the field technological process can be realized; and the evaluation index online calculation module captures measurement point hour data from a PI real-time database for calculation to thus judge whether ultra low emission desulfurization, denitration and dust removal facilities are put to operation according to the configuration information. Real-time online management on the operation condition of the ultra low emission facility of a coal-fired unit can be realized, the power environmental protection supervision range is expanded, and the power environmental protection supervision level is enhanced.

Description

technical field [0001] The invention relates to an online monitoring and management system, in particular to an online monitoring and management system for an ultra-low emission unit. Background technique [0002] In order to control coal-fired thermal power pollution, in recent years, domestic thermal power pollutant emission standards have become more and more stringent. In July 2014, China’s new thermal power air pollution emission standards, known as "the most stringent in history", began to be implemented. Strengthen the control of pollutant discharge in the power industry. With this environmental "curse" on their heads, many Chinese coal power companies have begun to explore the ultra-low emissions of natural gas standards, trying to get rid of the stereotype of the coal-fired industry as "black and rough". , China's coal-fired power atmospheric governance has extended to a new idea - ultra-low emissions. Ultra-low emissions, also known as "near-zero emissions" and "...

AI Technical Summary

Problems solved by technology

[0004] "Ultra-low emission" not only requires high one-time environmental protection investment, but also requires continuous investment in considerable operating costs. On the one hand, without corresponding economic subsidy measures, it is impossible for coal-fired power plants to maintain ultra-low or ultra-ultra-low design for a long time. On the other hand, due to the short operation time and insufficient engineering application experience of the projects put into operation, in order to prevent low-price competition and shoddy manufacturing of power generation companies, the environmental protection facilities cannot guarantee the operation effect of the facilities after they are put into operation, so the environmental protection facilities of coal-fired units should be strengthened Regulatory work after transformation

At present, the operation of environmental protection facilities after ultra-low emission transformation of coal-fired units has not been monitored in real time in China, and the assessment of ultra-low emission environmental protection electricity prices has not yet realized real-time online calculation. Relevant management departments cannot check the ultra-low emission operation status of coal-fired units in time and assessment index statistics
