Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission reduction assessment, and in particular to a method for evaluating carbon emission reduction by garbage classification using comprehensive data. Background Art

[0002] With the development of industrialization, the economies of countries around the world have achieved rapid growth, but the environmental problems caused by this have become a common challenge facing the world. The trend of global warming has further intensified and has gradually become one of the hot spots of international concern. Excessive greenhouse gas emissions are regarded as the main factor of global warming, leading to global warming, rising sea levels and increasing natural disasters, which have had an adverse impact on the ecological environment and sustainable economic development.

[0003] The existing garbage carbon emission intensity assessment relies on the monitoring of carbon dioxide concentration, but in fact the garbage carbon emission intensity analysis is also related to energy consumption, low calorific value, carbon content per unit calorific value and energy oxidation rate, which leads to large errors in garbage carbon emission reduction assessment. In addition, there is a lack of data comparison of garbage classification and processing, which affects the judgment of the overall data. There is a lack of analysis of the influencing factors of garbage carbon emission intensity, which leads to insufficient data support for subsequent garbage classification and processing, and the garbage classification carbon emission reduction assessment lacks intuitiveness. To this end, the present invention proposes a method for garbage classification carbon emission reduction assessment using comprehensive data to solve the above-mentioned problems. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a method for evaluating carbon emission reduction through garbage classification using comprehensive data, which solves the problems mentioned in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for evaluating carbon emission reduction by garbage classification using comprehensive data, specifically comprising the following steps:

[0008] Obtaining a garbage classification table, collecting basic data on carbon emission reduction of different types of garbage according to the garbage classification table, and then summarizing a number of basic data, wherein the basic data includes energy consumption, low calorific value, carbon content per unit calorific value, and oxidation rate of energy;

[0009] Calculating the carbon emission intensity of garbage based on the summarized basic data;

[0010] Classify the garbage, obtain the carbon emission intensity of the garbage after classification, and calculate the carbon emission intensity after classification and the carbon emission intensity before classification;

[0011] Evaluate the carbon emission reduction of garbage sorting based on the difference in carbon emission intensity data;

[0012] Obtain the types of garbage with high carbon emission intensity, trace the composition of the garbage, and perform control variable processing on the garbage composition in turn;

[0013] The influencing factors of carbon emission intensity are analyzed based on the garbage processed according to the control variables.

[0014] As an improved technical solution, the specific method of calculating the carbon emission intensity of garbage based on the basic data is:

[0015] First, the garbage is divided into several categories and marked as j, then the energy consumption corresponding to the j-type garbage is marked as Ej, then the average low calorific value of the j-type garbage is marked as DG, then the unit calorific value carbon content of the j-type garbage is marked as Cj, and then the energy oxidation rate of the j-type garbage is marked as Fj;

[0016] The coefficient for converting carbon to CO2 is then labeled k and calculated using the following formula: Among them, P is the carbon emission intensity of garbage.

[0017] As an improved technical solution, when the coefficient of carbon conversion into CO2 is marked as k, the implementation standard of k is 3.67, wherein the implementation standard of the energy oxidation rate Fj is 1.

[0018] As an improved technical solution, the carbon emission intensity data is obtained, the average value of the data is calculated, and invalid values ​​are eliminated. The specific method is:

[0019] First, several emission intensity data are marked as P1-PS, then threshold values ​​are set according to the data P1-PS and marked as (SA, SB), and then the data P1-PS is The data of (SA, SB) are eliminated, and the eliminated data are marked as Tj, where j is the sequence number of the eliminated data;

[0020] Then refer to the calculation formula: Where W is the average value of carbon emission intensity data.

[0021] As an improved technical solution, the specific method of evaluating the carbon emission reduction of garbage classification according to the difference value of the carbon emission intensity data is:

[0022] First, the carbon emission intensity of j types of garbage is calculated in sequence, namely P1, P1, ..., Pj, and then the carbon emission intensity of j types of garbage is summed up, that is, P 总 =P1+P1+, ..., +Pj, and then the calculated garbage carbon emission intensity P and P总 Make comparisons and evaluate the carbon emission reduction of garbage sorting.

[0023] As an improved technical solution, the calculated garbage carbon emission intensity P and P 总 The specific method for comparing and evaluating the carbon emission reduction assessment of garbage classification is as follows:

[0024] Reference calculation formula: If 0≤S≤10%, the carbon emission reduction assessment of waste classification is average; if 10%<S≤20%, the carbon emission reduction assessment of waste classification is good; if S>20%, the carbon emission reduction assessment of waste classification is excellent.

[0025] As an improved technical solution, the specific method of analyzing the influencing factors of carbon emission intensity of the garbage processed according to the control variables is:

[0026] Mark the garbage with the highest carbon emission intensity as GH, then divide the components in GH into several types and record them as n, then reduce one of the types n in turn, calculate GH again, and mark the result of each calculation as GHn;

[0027] The calculation results are plotted into a line graph, and the curvature of the line graph is analyzed, which is recorded as L. The position where L changes in a broken line is the component that has the highest impact on carbon emission intensity.

[0028] As an improved technical solution, the changing curvature of the analysis line graph is such that the position where L changes in a broken line is the component with the highest impact on carbon emission intensity. If L changes in a broken line in multiple places, then there are multiple components that affect carbon emission intensity.

[0029] (III) Beneficial effects

[0030] The present invention provides a method for evaluating carbon emission reduction by garbage classification using comprehensive data. Compared with the prior art, it has the following beneficial effects:

It can intuitively evaluate the carbon emission reduction from garbage sorting based on the difference in carbon emission intensity data, and at the same time analyze the influencing factors of garbage carbon emission intensity using the control variable method, providing data support for subsequent garbage sorting and processing. The use of comprehensive data analysis makes the carbon emission reduction evaluation from garbage sorting more intuitive. BRIEF DESCRIPTION OF THE DRAWINGS
