Method and device for determining thermal power plant construction space based on pm2.5 formation contribution rate

Abstract

The invention relates to a method and device for determining a construction space of a heat-engine plant on the basis of a PM2.5 forming contribution rate. The method comprises the following steps: obtaining a reference year polluted atmosphere discharge amount and a target year polluted atmosphere discharge amount of a preset type of an atmosphere pollution source; respectively obtaining a reference year high-temporal-spatial resoluted atmosphere discharge list and a target year high-temporal-spatial resoluted atmosphere discharge list; respectively inputting the reference year high-temporal-spatial resoluted atmosphere discharge list and the target year high-temporal-spatial resoluted atmosphere discharge list into an air quality model to obtain contribution from the heat-engine plant to the concentration of the PM2.5 in the reference year and contribution from the heat-engine plant to the concentration of the PM2.5 in the target year; and when the contribution from the heat-engine plant to the concentration of the PM2.5 in the target year is less than the contribution from the heat-engine plant to the concentration of the PM2.5 in the reference year, determining that the construction space of the heat-engine plant exists in the target year. According to the method for determining the construction space of the heat-engine plant, the rate of contribution from the heat-engine plant to the concentration of the PM2.5 is fully considered, and the method can be used for determining whether the heat-engine plant has the construction space or not on the basis of the rate of contribution to the concentration of the PM2.5.

Description

technical field [0001] The invention relates to the technical field of thermal power plants, in particular to a method and a device for determining the construction space of thermal power plants based on the PM2.5 formation contribution rate. Background technique [0002] Thermal power generation is the main force of domestic power generation, and its environmental protection capacity is an important part of the development plan of the electric power industry. Environmental capacity refers to the maximum amount of pollutants allowed to be discharged in order to achieve the environmental target value for a certain area, the environment as a whole or certain elements according to their natural purification capabilities, under specific pollution source layout and structural conditions. [0003] The traditional method of determining the construction space of thermal power plants is to deduce the allowable new thermal power installed capacity based on the maximum allowable emissi...
