Abstract

The invention discloses a three-dimensional space-time distribution processing method and device for air pollutant emission lists of thermal power plants and belongs to the field of pollutant emission lists and air pollution abatement. The method comprises the following steps of: obtaining an emission list of air pollutants in thermal power plants; distributing time to the emission list of air pollutants in the thermal power plants to obtain a monthly distribution coefficient, a daily distribution coefficient and a hourly distribution coefficient of air pollutants in the thermal power plants; distributing the national annual emissions of air pollutants in the thermal power plants to the provinces based on the amount of burned coal and the amount of power generation, and then using a spatial analysis tool to interpolate to the grids of an air quality model; distributing the emission amount of the air pollutants of the thermal power plants in each layer of atmospheric boundary layers, and obtaining a three-dimensional grid emission list of the air pollutants in the national thermal power plants after performing time and space distribution on the emission list of the air pollutants in the thermal power plants. The method and device can establish a three-dimensional grid air pollutant emission list of thermal power plants in China.

Description

technical field [0001] The invention relates to the fields of pollutant discharge inventory and air pollution control, in particular to a method and device for three-dimensional spatiotemporal distribution and processing of an air pollutant emission inventory of a thermal power plant. Background technique [0002] With the development of economy and society, the level of energy consumption in our country is increasing rapidly, and the discharge of pollutants remains high. The rapid economic development has promoted the rapid increase of the power scale. Thermal power generation generally refers to the use of heat generated by the combustion of fuels such as coal, oil and natural gas to heat water, turning the water into high-temperature, high-pressure water vapor, and then being driven by water vapor. The general term for the way generators generate electricity. my country's thermal power plants are mainly coal-fired, and thermal power has always occupied a pivotal position...
