Description

Technical Field

[0001] The present invention relates to the technical field of collaborative treatment of hazardous wastes, and in particular to a method for collaborative treatment of hazardous wastes and energy conservation and carbon reduction based on an intelligent platform. Background Art

[0002] Chemical parks are the product of modern chemical industry to adapt to resource or raw material conversion, conform to the development trend of large-scale, intensive, optimized, internationalized management and maximum benefits. After the end of World War II, foreign developed countries started to build chemical industry belts, which promoted the post-war economic recovery and take-off.

[0003] After chemical enterprises generate hazardous waste, they are temporarily stored in the temporary storage warehouse of hazardous waste in the factory. After communicating, confirming and signing the contract for entrusted treatment and disposal of hazardous waste with the hazardous waste treatment and disposal center, they are transferred to the temporary storage warehouse of the hazardous waste treatment and disposal center for temporary storage. The hazardous waste treatment and disposal center treats and disposes of the temporarily stored hazardous waste according to the production schedule. There are risks of temporary storage of hazardous waste in this process. The "3.21" extremely serious explosion accident at Jiangsu Xiangshui Tianjiayi Chemical Co., Ltd. is an extremely serious production safety responsibility accident caused by long-term illegal storage of hazardous waste, which led to spontaneous combustion and then caused an explosion.

[0004] The present invention aims to adjust the existing hazardous waste treatment and disposal process and determine the disposal plan based on demand. It is particularly suitable for chemical parks that are supporting the construction of venous industrial parks or hazardous waste treatment and disposal centers. According to the generation and temporary storage of hazardous wastes in the park enterprises, through the compatibility model, weighted compatibility model, hazardous waste collaborative treatment and energy-saving and carbon reduction calculation model, the hazardous waste treatment production plan of the hazardous waste treatment and disposal center is optimized, the hazardous waste temporary storage period is reduced, the hazardous waste treatment and disposal compatibility is optimized, and the goals of pollution reduction and carbon reduction are achieved simultaneously. Summary of the invention

[0005] The technical problem solved by the present invention is that the temporary storage period of hazardous waste in chemical parks is long and the treatment and disposal is difficult, and the existing treatment and disposal methods still cause great pollution to the environment.

[0006] To solve the above problems, the technical solution of the present invention is as follows:

[0007] A method for collaboratively treating hazardous waste and reducing energy consumption and carbon emissions based on a smart platform, comprising the following steps:

[0008] S1. Obtaining the temporary storage data of hazardous wastes and the comprehensive data of hazardous waste compatibility settings;

[0009] S2. Generate hazardous waste compatibility and hazardous waste treatment and disposal plan list and energy saving and carbon reduction, and output to the data analysis module, including the following:

[0010] Based on the temporary storage situation of unit hazardous waste, the hazardous waste treatment and disposal center prioritizes hazardous waste with large temporary storage quantities and approaching temporary storage periods in the hazardous waste treatment and disposal plan list through the data center. Then, through the compatibility matching model, weighted matching model, and calculation model for co-treatment of hazardous waste and energy conservation and carbon reduction, a complete hazardous waste treatment and disposal plan list, the CO2 emissions after co-treatment of hazardous waste are obtained and output to the data analysis module;

[0011] S3. The data analysis module statistically analyzes the data in the hazardous waste treatment and disposal plan list.

[0012] Furthermore, step S1 includes the following: The intelligent platform stores the hazardous waste temporary storage data in the data center through the first input module and stores the hazardous waste compatibility setting data in the data center through the second input module.

[0013] Furthermore, step S2 includes the following steps:

[0014] S2-1. The compatibility matching model uses the matrix method to analyze the compatibility of the hazardous waste in the hazardous waste treatment and disposal plan list, and obtains the compatible hazardous waste types and incompatible hazardous waste types;

[0015] S2-2. The weighted matching model determines the controlled items and controlled values of the hazardous waste through the combustion principle and design conditions, forms the matching principle. After determining the matching principle, a matrix equation is established, and the mass ratio range of each hazardous waste participating in the matching is obtained through the weighted algorithm. Through the above constraints, a hazardous waste matching and hazardous waste treatment and disposal plan list including the hazardous waste incineration matching plan is formed. When the quality control value is determined, the maximum disposal amount of a certain type of hazardous waste is calculated, and the obtained hazardous waste matching and hazardous waste treatment and disposal plan list is output to the data analysis module through the first output module;

[0016] S2-3. The calculation model for co-treatment of hazardous waste and energy conservation and carbon reduction calculates the CO2 emissions after co-treatment of hazardous waste, and outputs the CO2 emissions after co-treatment of hazardous waste to the data analysis module through the second output module.

[0022] When C i = 1, it indicates that the compatibility between the i-th type of hazardous waste and other hazardous wastes is good,

[0023] When C i = 0, it indicates that the i-th type of hazardous waste is prohibited from being mixed with other hazardous wastes,

[0024] When 0 < C i < 1, then sort the compatibility of all hazardous wastes. After deleting the hazardous waste with the smallest compatibility coefficient, recalculate the compatibility coefficient for the remaining hazardous wastes. If the compatibility coefficients of the remaining hazardous wastes are all 1, it indicates that the compatibility among the remaining hazardous wastes is good; otherwise, repeat deleting the hazardous waste with the smallest compatibility coefficient until the compatibility coefficients of all hazardous wastes meet 1,

Obtain the temporary storage data of hazardous waste and the comprehensive data of the compatibility setting of hazardous waste, including the following: The intelligent platform stores the temporary storage data of hazardous waste in the data center through the first input module, and stores the compatibility setting data of hazardous waste in the data center through the second input module;

[0092] S2. Generate a list of hazardous waste compatibility, hazardous waste treatment and disposal plans, and the amount of energy conservation and carbon reduction, and output it to the data analysis module, including the following:

[0093] Based on the temporary storage situation of unit hazardous waste, the hazardous waste treatment and disposal center preferentially includes the hazardous waste with a large temporary storage amount and an approaching expiration of the temporary storage period in the list of hazardous waste treatment and disposal plans through the data center, and then obtains a complete list of hazardous waste treatment and disposal plans, the CO2 emissions after the collaborative treatment of hazardous waste through the compatibility matching model, weighted matching model, and hazardous waste collaborative treatment and energy conservation and carbon reduction calculation model, and outputs them to the data analysis module, including the following steps:

[0094] S2-1. The compatibility matching model uses the matrix method to analyze the compatibility of the hazardous waste in the list of hazardous waste treatment and disposal plans, and obtains the types of hazardous waste that can be compatible and the types of hazardous waste that cannot be compatible, including the following:

After deleting the hazardous waste with the smallest compatibility coefficient, the compatibility coefficients of the remaining hazardous wastes are recalculated. If the compatibility coefficients of the remaining hazardous wastes are all 1, it indicates that the compatibilities among the remaining hazardous wastes are good. Otherwise, the hazardous waste with the smallest compatibility coefficient is repeatedly deleted until the compatibility coefficients of all hazardous wastes are 1.
