Features of various embodiments of the present application may be combined with each other without conflict.
FIG. 1 shows a schematic flow chart of a greenhouse gas emission amount accounting method according to an embodiment of the present application; as shown in fig. 1, a greenhouse gas emission amount accounting method 100 according to an embodiment of the present application may include the following steps S101 and S102:
in step S101, according to the target accounting system requirement of the waste incineration power plant, selecting a corresponding emission source formula from a pre-constructed emission source formula library, selecting a corresponding target emission factor from a pre-constructed emission factor library, and selecting a corresponding target greenhouse gas accounting formula from a pre-constructed greenhouse gas accounting formula library according to the emission source formula and the target emission factor.
The waste incineration power generation in the embodiment of the application refers to the work of introducing, digesting, absorbing and re-creating a waste incineration plant and waste incineration equipment.
Greenhouse gases are, among others, gaseous components naturally present in the atmosphere and generated by human activity, such as carbon dioxide (C), capable of absorbing and emitting radiation generated by the earth's surface, the atmosphere and the cloud, having a wavelength in the infrared spectrum 2 O), methane CH4, nitrous oxide N 2 O, hydrofluorocarbons (HFCs), and the like.
The emission source is a source of a pollution factor causing environmental pollution. Generally to a location, equipment or installation in the environment that emits pollutants or releases harmful agents.
In one embodiment of the present application, before selecting a corresponding emission source formula from a pre-constructed emission source formula library, selecting a corresponding target emission factor from a pre-constructed emission factor library, and selecting a corresponding target greenhouse gas accounting formula from a pre-constructed greenhouse gas accounting formula library according to the emission source formula and the target emission factor, the method further comprises: a1, identifying historical emission characteristics of greenhouse gases emitted by the waste incineration power plant, configuring an emission source greenhouse gas accounting formula according to the historical emission characteristics, and forming an emission source formula library; a2, determining an emission boundary according to a target accounting system of the waste incineration power plant; a3, constructing the greenhouse gas accounting formula library according to the emission boundary; a4, constructing the emission factor library according to the emission boundary; and A5, forming a greenhouse gas emission characteristic database updated in a preset time interval according to the activity data type of the waste incineration power plant and the greenhouse gas emission characteristic data.
Wherein, the emission factor refers to the greenhouse gas emission coefficient representing the unit production or consumption activity.
Since the current greenhouse gas list compilation mainly refers to the 1996 list guide, the 2006 list guide and the 2019 list guide, emission factors are different in different list guides, such as FFC, FCC, water content and the like, and the emission factors are set as default values. Therefore, in the application, the value range and the source of the emission factor are separately managed to form an emission factor library, so that the application of researchers is facilitated.
In one embodiment of the present application, constructing a discharge factor library based on the discharge boundary comprises: b1, adding emission factors corresponding to the greenhouse gases from different sources into the emission factor library; and B2, adding the emission factors corresponding to the greenhouse gases with different values and the same source into the emission factor library.
The method and the device can add the emission factors into the emission factor library at any time according to the source change condition of the greenhouse gases, and facilitate online maintenance of data such as the emission factors of the waste incineration discharge capacity.
For example, factors that may be included in the emission factor library are factors from related methodologies, including: the system comprises a methane global warming trend, a nitrous oxide global warming trend, a model correction coefficient, an oxidation coefficient, a methane proportion (volume) in exhaust gas, a degradable DOC proportion, a methane emission correction coefficient, a degradable organic carbon proportion in garbage type j, a degradation rate of garbage type j, a proportion of fossil carbon in garbage type j to total carbon content, a carbon content proportion in garbage j, an average calorific value of consumed fuel, a diesel/coal weighted average CO2 emission factor, a maximum methane production capacity, a methane conversion factor, a methane emission factor in a garbage treatment mode, a nitrogen dioxide emission factor related to the garbage treatment mode and the like.

Generally, the mainstream treatment processes of domestic garbage treatment are landfill and incineration. Methane and carbon dioxide generated in the landfill process are greenhouse gases, the duration is long, the controllability is not strong enough, and the greenhouse gas effect of the methane is 28 times that of the carbon dioxide. Compared with the landfill, the garbage incineration power generation can convert garbage into carbon dioxide and heat energy in a short time, has better controllability, can avoid methane emission in the landfill process, can also replace fossil fuel by heat energy recovery power generation, and has double carbon emission reduction effects of methane emission control and power generation replacement.
In the embodiment of the application, when data such as waste incineration discharge capacity discharge factors are selected for accounting, each region can be configured to calculate the electric quantity marginal discharge factor (OM) and the capacity marginal discharge factor (BM), a combined marginal discharge factor (CM) is obtained according to OM and BM coefficients, and a corresponding combined marginal discharge factor is selected according to the region where a waste incineration power plant is located when the discharge reduction of projects is calculated.
With the continuous emergence of new production processes and technologies for waste incineration, new emission characteristics are brought, and researchers need to identify and research the emission characteristics and update a characteristic database in time. And configuring an emission source accounting formula according to the updated feature database to generate an emission source formula library. For each emission source, different accounting methods may be available according to different accounting standards, and therefore, different emission source accounting formulas may be configured for different emission sources to form an emission source formula library. After project boundaries are determined, emission source formulas are selected from the emission source formula library according to research needs to be combined to form a greenhouse gas accounting formula, and a greenhouse gas accounting formula library is formed, so that when greenhouse gas accounting is carried out, an accounting formula is selected from the accounting formula library to carry out accounting.
In step S102, the greenhouse gas emission amount of the waste incineration power plant is calculated according to the target greenhouse gas calculation formula and the target activity data.
In one embodiment of the present application, the calculating greenhouse gas emission amount of the waste incineration power plant according to the target greenhouse gas accounting formula and the target activity data accounting comprises: and calculating the total emission and the reference emission according to the target greenhouse gas calculation formula, the target emission factor and the target activity data, and calculating the greenhouse gas emission according to the total emission and the reference emission.
The greenhouse gas emission of the waste incineration power plant mainly comprises greenhouse gas emission generated by electricity consumed by the project, greenhouse gas emission generated by blending combustion of fossil fuel, and greenhouse gas CO generated by waste incineration 2 、N 2 O and CH4 emissions and emissions resulting from waste water management. The formula for calculating the emission reduction of greenhouse gases in the waste incineration power plant is as follows:
PE reduce ＝PE y -BE EC,y -BE CH4,SWDS,y (1)
