Abstract

The invention discloses an environmental and economic performance comprehensive evaluation method for thermal power plant typical environmental protection engineering and relates to evaluation of environmental and economic performance of thermal power plant typical pollutant control units. The problem that comprehensive evaluation of environmental and economic performance of existing thermal power plant typical pollutant control units is not sufficient is solved. The method includes the steps that firstly, an environmental and economic performance index system of the thermal power plant typical environmental protection engineering is established, and membership functions are established for evaluation indexes; weights of the evaluation indexes in all levels of evaluation are determined according to an actual running parameter and the technical requirement; a fuzzy mathematics comprehensive evaluation method is utilized, a large membership principle is adopted, environmental evaluation and economic evaluation are performed on the environmental protection engineering, and finally the environmental and economic performance of the environmental protection engineering is comprehensively evaluated. The method has universal applicability and operability, the result of the method can reflect advantages and disadvantages of the environmental and economic performance of the existing pollutant control units, the specific problems of the pollutant control units and reasons causing the problems are indicated, and the energy conservation and emission reduction development direction of a thermal power plant is guided.

Description

technical field

[0001] The invention belongs to the field of comprehensive evaluation of typical pollutant control units in thermal power plants, and is a method for comprehensively evaluating the environment and economic performance of typical environmental protection projects in thermal power plants. Background technique

[0002] In recent years, the environment has deteriorated day by day. In order to strengthen the control of pollutants, my country has formulated strict pollutant discharge standards for coal-fired power plants. Therefore, thermal power generation companies have launched desulfurization, denitrification, and dust removal projects one after another. The characteristics are investment, operation and Maintenance costs are high. Therefore, on the premise of meeting the pollutant discharge standards, saving resources and costs, and achieving maximum economic benefits, it is of great practical significance to scientifically evaluate the environmental and economi...

Examples

Embodiment Construction

[0017] The present invention will be further described in detail below in combination with specific embodiments. The environmental and economic evaluation method of a typical environmental protection project of a thermal power plant of the present invention should include the following steps.

[0018] 1. Consider the status quo of environmental protection projects and the impact of various indicators on the environment and economy, and combine the research of some scholars to establish an evaluation index system. The establishment of the evaluation index system of typical environmental protection projects in thermal power plants The indicators include the environmental performance indicators and economic performance indicators of desulfurization, denitrification, and dust removal projects in thermal power plants, as follows: desulfurization environmental indicators include the impact of desulfurization wastewater on the environment, the concentration of SO2 in outlet flue gas, ...
