Coal-fired power plant flue gas purification island operation health evaluation system and method

Abstract

The invention discloses a coal-fired power plant flue gas purification island operation health evaluation system and method. The evaluation system is constructed by a three-level direct index, a two-level indirect index and a one-level comprehensive index; the first-level comprehensive index is an operation health index and is obtained by performing weighted summation on the second-level indirect index; the secondary indirect indexes comprise an environmental protection index, an economic index and a reliability index; and the third-level direct indexes comprise an environmental protection index, an economic index and a reliability index, and the indexes are respectively subjected to weighted summation and then are in one-to-one correspondence with the environmental protection index, the economic index and the reliability index of the second-level indirect index. The provided comprehensive evaluation system covers three main dimensions of environmental protection, economy and reliability and comprises 25 direct indexes, and detailed evaluation and scoring of all factors such as process, equipment, material consumption, energy consumption, environmental protection indexes and reliability are realized.

Description

technical field [0001] The invention belongs to the technical field of flue gas pollutant control in coal-fired power plants, and in particular relates to an operation health evaluation system and method for a flue gas purification island in a coal-fired power plant. Background technique [0002] Fighting the battle of pollution prevention and control and solving the outstanding environmental problems that the people complain about are not only an urgent need to improve the environment and people's livelihood, but also a top priority for strengthening the construction of ecological civilization. The state has issued a series of policies and measures to require thermal power plants to implement ultra-low emission transformation. At present, most coal-fired power plants have achieved ultra-low emission. After the ultra-low emission transformation of coal-fired power plants is completed, the environmental protection level of the flue gas purification island has generally improv...

AI Technical Summary

Problems solved by technology

After the ultra-low emission transformation of coal-fired power plants is completed, the environmental protection level of the flue gas purification island has generally improved, but there are still common problems such as high energy consumption, high material consumption, uneconomical operation, large fluctuations in environmental protection indicators, and insufficient operational reliability.

The flue gas purification island system of coal-fired power plants is complex, with various equipment and many links. At present, there is no standardized and effective evaluation system and evaluation method to evaluate and optimize the operation health status, which affects the improvement of the operation health level of the flue gas purification island.
