Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and particularly relates to a waste treatment method. Background Art

[0002] Existing waste treatment methods mainly include landfill, incineration, composting, etc.

[0003] Landfill is the most common waste treatment method at present. Its advantages are relatively low cost and large treatment capacity. However, leachate and landfill gas will be generated during the landfill process, which will cause serious pollution to soil, groundwater and the atmosphere. Incineration can significantly reduce the volume and weight of waste and generate heat energy for power generation, but harmful substances such as dioxins and heavy metals will be generated during the incineration process. Composting is mainly applicable to organic waste, but the composting process has strict requirements on parameters such as the moisture content and carbon-nitrogen ratio of waste. When the requirements are not met, the waste treatment efficiency will be seriously affected.

[0004] In addition to the above three main methods, there are also some other waste treatment methods, such as anaerobic digestion, pyrolysis, etc., which can improve the resource utilization rate of waste to a certain extent. However, there is a key problem in existing waste treatment methods: the lack of dynamic adjustment ability, which makes it difficult to carry out targeted adjustment and optimization, thus affecting the waste treatment efficiency. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a waste treatment method.

[0006] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary part is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the subsequent detailed description.

[0011] During the same working cycle, when the waste to be incinerated of this configuration classification is obtained again, it is judged whether the recorded weight difference after the last incineration treatment is greater than the adjustment threshold. If so, the immediate application working parameters bound to this weight difference are adjusted to generate adjusted and optimized immediate application working parameters.

[0012] Further, after obtaining the configuration classification of the waste to be incinerated, it further includes: judging whether the obtained configuration classification of the waste to be incinerated is the configuration classification of the waste to be incinerated that appears for the first time in the current working cycle. If so, the original set working parameters corresponding to this first-occurring configuration classification of the waste to be incinerated are extracted from the reference operation database as the immediate application working parameters required for incinerating the waste of this configuration classification; wherein, the reference operation database stores the original set working parameters for incinerating the waste to be incinerated of each configuration classification by the incineration module.

[0013] Further, after generating the adjusted and optimized immediate application working parameters, it further includes: binding the generated adjusted and optimized immediate application working parameters to the recorded weight difference after the last incineration treatment, and updating and recording them in the temporary database;

[0014] After obtaining the configuration classification of the waste to be incinerated, it further includes: judging whether the obtained configuration classification of the waste to be incinerated is the configuration classification of the waste to be incinerated that appears for the first time in the current working cycle. If not, the adjusted and optimized immediate application working parameters are used as the immediate application working parameters required for incinerating the waste of this configuration classification.

[0015] Further, during the same working cycle, when the waste to be incinerated of this configuration classification is obtained again, it is judged whether the recorded weight difference after the last incineration treatment is greater than the adjustment threshold. If not, the last recorded immediate application working parameters corresponding to the waste to be incinerated of this configuration classification are extracted from the temporary database as the immediate application working parameters required for incinerating the waste of this configuration classification.

[0016] Further, the waste treatment method further includes: after the current working cycle ends, obtaining all the immediate application working parameters used for the waste to be incinerated of each configuration classification in the temporary database, and recording and storing them in the reference operation database; clearing the temporary database.

[0017] Further, before obtaining the configuration classification of the waste to be incinerated, it further includes: analyzing and matching the waste to obtain waste to be incinerated of multiple configuration classifications;

[0018] The process of analyzing and matching the waste includes:

[0019] Samples are collected from various types of waste and pre-treated to meet the detection requirements. The types of waste include: fibrous waste, viscous waste, resin block waste, paint sludge waste, paper waste, highly toxic waste, hard packaging waste, and plastic waste;

[0020] The samples are measured to obtain the property data of various types of waste. The property data includes: higher calorific value, density, VOC content, halogen content, heavy metal content, and acidic pollutant content;

[0021] Obtain the capacity of the incineration module, the single waste treatment volume, and the designed calorific value range;

[0022] According to the environmental protection treatment requirements and the capacity of the incineration module, the single waste treatment volume, and the designed calorific value range, a compatibility model is established, and the content of each type of waste is used as a variable of the compatibility model, and the compatibility principle is used as a constraint condition of the compatibility model;

[0023] Input the property data of each type of waste into the established compatibility model, solve the compatibility model, and obtain the compatibility ratio of each type of waste;

[0024] Classify each type of waste according to the obtained compatibility ratio to obtain multiple combinations of mixed waste, that is, multiple configured classifications of waste to be incinerated.

[0025] Further, the compatibility principle refers to the need to simultaneously meet the following conditions: the calorific value of the mixed waste is within a preset range; the calorific value difference and density difference of each type of waste in the mixed waste are within a preset range; the VOC content, halogen content, heavy metal content, and acidic pollutant content of the mixed waste are lower than the preset threshold; no adverse reactions occur between different types of waste in the mixed waste.

[0026] Further, the waste treatment method further includes: analyzing the chemical composition of each type of waste, predicting potential reactions that may occur in the mixed waste, and when setting the constraint conditions of the compatibility model according to the compatibility principle, limiting that no adverse reactions occur between different types of waste.

[0027] Further, before analyzing and matching the waste, it also includes:

[0028] According to geographical, administrative, and / or functional boundaries, delimit the waste treatment area, and divide the waste within the waste treatment area into multiple categories. The categories of waste include: sludge, liquid waste, hazardous waste, and solid waste;

[0029] Separate data collection is carried out for each category of waste to obtain the generation volume, physical properties, chemical composition, and calorific value of each category of waste within the waste treatment area.

[0031] The daily production volume, monthly production volume, annual production volume of waste in each category, and the variation rules of the daily cycle, weekly cycle, monthly cycle, and annual cycle of the production volume;

[0032] The proportion of waste in each category in the total waste volume;

[0033] The chemical composition data of waste in each category;

[0034] The production volume and treatment requirements of waste in the next few years predicted based on historical data and future development plans.

[0035] Furthermore, before analyzing and matching the waste, it also includes: designing a waste treatment system and the scale of each module in the waste treatment system according to the result report;

[0036] Among them, the waste treatment system includes: a waste treatment module, an incineration module, a heat energy utilization module, a waste utilization module, a tail gas treatment module, and an ash and slag collection and transportation module;

[0037] After analyzing and matching the waste, it is transported into the incineration module for incineration treatment. The heat generated by the incineration is distributed and reused through the heat energy utilization module. The ash and slag generated by the incineration are collected, stored, and transported through the ash and slag collection and transportation module. The waste utilization module conducts resource allocation and utilization on the directly reusable products after being treated by the waste treatment module. The tail gas treatment module is used to purify dust, acidic gases, NOX, dioxins, and heavy metal pollutants.

[0038] The beneficial effects brought by the present invention: By limiting the working cycle and dynamically adjusting the incineration parameters, it can ensure that the incineration treatment is always carried out in the best state, which can not only improve the incineration efficiency, but also flexibly respond to the treatment requirements of different configured classified wastes and the indefinite update of the analysis and matching, making the dynamic adjustment process more in line with the actual situation and the adjustment more accurate. Finally, the cross-incineration of different configured classified wastes is realized, maximizing the utilization rate of the incineration module. In addition, by binding and adjusting the weight difference and the immediate application working parameters, it can ensure that the combustion degree of the waste reaches the expected standard, improve the incineration quality, and reduce secondary pollution. Description of the Drawings

[0039] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings required in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other accompanying drawings can be obtained based on these drawings.

[0040] Figure 1 It is a schematic flowchart of a waste treatment method of the present invention. Detailed implementation manners

[0041] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings. It should be clear that the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] As Figure 1 shown, in some illustrative embodiments, a waste treatment method is provided, including:

[0043] 101: Area demarcation and waste analysis.

[0044] According to geographical, administrative, and / or functional boundaries, demarcate the waste treatment area. It can be divided according to natural geographical features, such as rivers, mountains, etc. For example, it can be demarcated with a certain river as the boundary, dividing the upstream and downstream into two treatment areas. It can be divided according to the existing administrative divisions, such as provinces, cities, districts, streets, etc. For example, it can be demarcated with the administrative area of a certain city as the boundary, dividing different waste treatment areas. It can be divided according to the main functions of the area, such as industrial areas, commercial areas, residential areas, agricultural areas, etc. For example, it can be demarcated with a certain industrial park as the boundary, dividing an independent waste treatment area.

[0045] In actual operation, it is often necessary to comprehensively consider the above three types of boundaries and flexibly demarcate according to the actual situation. For example, it can be based on a certain administrative area and combined with its internal functional divisions to further refine the waste treatment area. At the same time, the demarcated waste treatment area should be convenient for waste collection, transportation, and treatment, and the waste treatment cost should be considered to minimize the transportation cost and treatment cost. Preferably, establish a file for each demarcated waste treatment area, recording information such as its name, boundary range, area, population, main function, main industry, existing waste treatment facilities, etc.

[0046] The waste in the waste treatment area is divided into multiple categories, including: sludge, liquid waste, hazardous waste, and solid waste. Sludge mainly refers to the sludge generated in urban sewage treatment plants and industrial wastewater treatment processes, as well as the silt generated from the dredging of water bodies such as rivers and lakes. Liquid waste mainly refers to the wastewater generated in industrial production processes, laboratory wastewater, medical wastewater, etc. Hazardous waste refers to waste with one or more hazardous characteristics such as toxicity, corrosiveness, flammability, reactivity, or infectivity, such as waste batteries, waste lamp tubes, waste drugs, waste paint, etc. Solid waste refers to other solid wastes other than sludge, liquid waste, and hazardous waste, mainly including: domestic waste, industrial solid waste, agricultural solid waste, and construction waste.

[0047] Data collection is carried out separately for each category of waste to obtain the generation quantity, physical properties, chemical composition, and calorific value of each category of waste in the waste treatment area.

[0048] The data collection methods include: designing questionnaires to collect waste generation information from enterprises and residents; establishing a data sharing mechanism with environmental protection departments, sanitation departments, relevant enterprises, etc. to obtain existing waste data; sampling different types of waste and sending them to the laboratory for physical property and chemical composition analysis; consulting relevant literature and reports to obtain relevant information on waste generation and characteristics.

[0049] After the data collection is completed, a database is established to record and store the collected data according to information such as waste treatment area, waste category, and time.

[0050] Among them, the generation quantity data includes: daily generation quantity, that is, the weight or volume of each category of waste generated daily in each waste treatment area is statistically calculated; monthly generation quantity, that is, the weight or volume of each category of waste generated monthly in each waste treatment area is statistically calculated; annual generation quantity, that is, the weight or volume of each category of waste generated annually in each waste treatment area is statistically calculated.

[0051] The physical property data includes: composition, for example, the proportion of various components such as plastics and papers in domestic waste; moisture content, that is, the content of water in the waste; bulk density, that is, the weight per unit volume of the waste; particle size, that is, the particle size distribution of the waste.

[0052] The chemical composition data includes: elemental analysis data, for example, the content of elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur in the waste; heavy metal content data, for example, the content of heavy metals such as lead, cadmium, chromium, mercury, and arsenic in the waste; organic matter content data, for example, the content of volatile solids or chemical oxygen demand in the waste; pH value, that is, the acidity or alkalinity of the waste.

[0053] Calorific value is the heat released by the complete combustion of unit weight of waste.

[0054] Sort, clean, and statistically analyze the collected data, calculate indicators such as the generation quantity, physical properties, chemical composition, and calorific value of waste in each category, and output a result report. The result report includes: the daily, monthly, and annual generation quantities of waste in each category, as well as the variation rules of the daily, weekly, monthly, and annual cycles of the generation quantity; the proportion of waste in each category in the total waste quantity; the chemical composition data of waste in each category; and the predicted generation quantity and treatment requirements of waste in the next few years based on historical data and future development plans.

[0055] The variation rules of the generation quantity include: the daily variation rules of the generation quantity of waste in each category within a week, for example, which wastes have a higher generation quantity on weekends; the weekly variation rules of the generation quantity of waste in each category within a month, for example, which wastes have a higher generation quantity at the beginning of the month; the monthly variation rules of the generation quantity of waste in each category within a year, for example, which wastes have a higher generation quantity in summer; and the variation trend of the generation quantity of waste in each category over the years, for example, which wastes show an increasing trend year by year. By analyzing the proportion of waste in each category in the total waste quantity, the main composition of regional waste can be analyzed. Analyzing the physical properties and chemical composition of waste in each category can provide a basis for the design of subsequent waste treatment plans.

[0056] Analyze historical data to obtain the relationships between waste generation quantity and factors such as population, economic development, and industrial structure. Collect information on the future development plans of the region, such as population growth predictions and industrial development plans. Based on historical data and development plans, establish a prediction model to predict the generation quantity and treatment requirements of waste in each category in the next few years, such as 5 years, 10 years, and 20 years.

[0057] Through regional demarcation, waste classification, data collection, and data analysis, the generation situation, characteristics, and future trends of regional waste can be grasped, providing a basis for the design of subsequent waste treatment plans, facility construction, and operation management, and ultimately achieving the reduction, resource utilization, and harmless treatment of waste.

[0058] 102: Design a waste treatment system.

[0059] Design a waste treatment system and the scale of each module in the waste treatment system according to the characteristics, generation quantity, variation rules, and future predictions of waste in each category in the result report.

[0060] Among them, the waste treatment system includes: a waste treatment module, an incineration module, a heat energy utilization module, a waste utilization module, a tail gas treatment module, and an ash and slag collection and transportation module.

[0061] The waste treatment module is used to pre-treat waste, such as crushing, sorting, dewatering, drying, etc., to prepare for subsequent treatment. For example, according to the treatment requirements of different types of waste, determine the treatment capacity of equipment such as crushers, sorters, and dewatering machines.

[0062] An incineration module, which is used to incinerate the pretreated waste at high temperature to achieve reduction, harmlessness and energy conversion. For example, according to the total amount and calorific value of the waste, determine the capacity, quantity and type of the incinerator.

[0063] A heat energy utilization module, which is used to recover the heat generated by incineration and then used for power generation, heating, refrigeration, etc., to achieve the reuse of energy. For example, according to the heat generated by incineration, determine the capacity of equipment such as waste heat boilers, steam turbines, generators, etc.

[0064] A waste utilization module, which is used to recycle and resourcefully utilize the waste that can be directly reused after pretreatment, such as waste metals, plastics, papers, etc. For example, according to the types and quantities of recyclable waste, determine the scale of the corresponding recycling and treatment equipment.

[0065] An exhaust gas treatment module, which is used to purify the exhaust gas generated by incineration, remove pollutants such as dust, acidic gases (SOx, HCl, etc.), nitrogen oxides (NOx), dioxins and heavy metals, and meet the emission standards. For example, according to the exhaust gas volume and pollutant emission standards, determine the treatment capacity of equipment such as dust collectors, acid scrubbers, denitration devices, activated carbon injection devices, etc.

[0066] An ash and slag collection and transportation module, which is used to collect, store and transport the ash and slag generated by incineration, and send them to a designated landfill or for further treatment and resource utilization. For example, according to the ash and slag generation amount, determine the capacity of the ash and slag storage facility and the scale of the transport vehicles.

[0067] The designed waste treatment system should be matched with the waste characteristics, generation amount and regional characteristics, and at the same time consider the construction cost, operation cost and maintenance cost.

[0068] The waste after being analyzed and formulated is transported to the incineration module for incineration treatment. The heat generated by incineration is distributed and reused through the heat energy utilization module. The ash and slag generated by incineration are collected, stored and transported through the ash and slag collection and transportation module. The waste utilization module conducts resource allocation and utilization on the directly reusable products after being treated by the waste treatment module. The exhaust gas treatment module is used to purify dust, acidic gases, NO X , dioxins and heavy metal pollutants.

[0069] 103: Analyze and formulate the waste to obtain the waste to be incinerated with multiple configuration classifications, ensure the stability, high efficiency and environmental protection of the incineration process, and maximize resource utilization.

[0070] The process of analyzing and formulating the waste includes:

[0071] First, collect samples from various types of waste and pre-treat the samples to meet the detection requirements. The types of waste include: fibrous waste, viscous waste, resin block waste, paint sludge waste, paper waste, highly toxic waste, rigid packaging waste, and plastic waste.

[0072] From each type of waste, collect representative samples according to their proportion in the total waste volume. Specifically, methods such as random sampling, stratified sampling, and systematic sampling can be used to ensure the representativeness of the samples, and determine the appropriate sampling volume according to the detection requirements and waste characteristics.

[0073] The purpose of pre-treating the samples is to make the samples meet the requirements of subsequent detection instruments and analysis methods. Specifically, it can include: crushing, breaking large pieces of waste into smaller sizes; mixing, mixing multiple samples of the same type of waste evenly to reduce sample differences; drying, removing moisture from the samples to ensure the accuracy of detection data, especially for calorific value determination; grinding, grinding the samples into finer particles to improve detection accuracy; screening, screening the samples as needed to separate components of different particle sizes; special treatment, for highly toxic waste, special safety protection measures need to be taken for sampling and pre-treatment to prevent environmental pollution and endanger the health of personnel.

[0074] Then, measure the samples to obtain the property data of each type of waste. The property data includes: higher heating value, density, VOC content, halogen content, heavy metal content, and acidic pollutant content.

[0075] The higher heating value measures the total heat released when the waste is completely burned and is an important parameter in the incineration process. It can be measured by the calorimeter method. The density affects the storage, transportation, and feeding efficiency of the incineration module and is measured by the weighing method, volume displacement method, etc. The VOC content measures the content of volatile organic compounds in the waste. VOCs may produce harmful gases during incineration, so it needs to be measured for key control during waste treatment and is measured by gas chromatography-mass spectrometry, infrared spectroscopy, etc. The halogen content, especially the chlorine content, is prone to generating highly toxic substances such as dioxins during combustion and is a key index that needs to be strictly controlled during the blending process and is measured by ion chromatography, X-ray fluorescence spectrometry, etc. The heavy metal content, such as lead, mercury, cadmium, chromium, etc., may volatilize or remain in the ash during incineration, and its content needs to be strictly controlled and is measured by atomic absorption spectrometry, inductively coupled plasma mass spectrometry, etc. The acidic pollutant content, such as sulfates, nitrates, etc., may generate acidic gases such as SOx, NOx during incineration, and its content needs to be controlled and is measured by titration method, ion chromatography, etc.

[0076] Then, obtain the capacity of the incineration module, the single waste treatment volume, and the designed calorific value range.

[0077] The capacity of the incineration module refers to the total amount of waste that the incineration module can process per hour or per day. The single waste treatment capacity refers to the amount of waste that can be processed after each feeding. The designed calorific value range refers to the range of waste calorific values required for the optimal operation of the incineration module.

[0078] Then, a compatibility model is established according to the environmental protection treatment requirements, the capacity of the incineration module, the single waste treatment capacity, and the designed calorific value range. The content of each type of waste is used as a variable in the compatibility model, and the compatibility principle is used as a constraint condition for the compatibility model. The environmental protection treatment requirements refer to the emission standards for waste incineration, such as the emission limits for soot, SO x 、NO x 、dioxins, heavy metals, etc.

[0079] Then, the property data of each type of waste are input into the established compatibility model, and the compatibility model is solved to obtain the compatibility ratio of each type of waste.

[0080] The higher calorific value, density, VOC content, halogen content, heavy metal content, and acid pollutant content of each type of waste measured are input into the established compatibility model. The mathematical optimization method is used to solve the compatibility model. When the objective function and constraint conditions in the model are both linear, the linear programming method can be used for solution. When there is a non-linear relationship in the objective function or constraint conditions in the model, the non-linear programming method needs to be used for solution. When the decision variables in the model are required to be integers, the integer programming method needs to be used for solution. The optimization objective can be to minimize costs, maximize resource utilization rate, minimize pollutant emissions, etc., which is selected according to the actual situation. After solution, the optimal compatibility ratio of each type of waste is obtained.

[0081] The calculated compatibility ratio is tested on a small scale to verify its feasibility and effect, and the compatibility ratio is adjusted according to the test results.

[0082] Finally, each type of waste is classified according to the obtained compatibility ratio to obtain multiple combinations of mixed waste, that is, multiple configurations of waste to be incinerated. These mixed wastes meet the requirements of the incineration module in terms of calorific value, pollutant content, etc., and can be incinerated safely, efficiently, and environmentally.

[0083] Through formulation, the calorific value of the mixed waste can be stabilized within the optimal operating range of the incineration module, improving the combustion efficiency of the incinerator and reducing the consumption of auxiliary fuels. By controlling the content of pollutants such as halogens, heavy metals, and VOCs in the mixed waste, the generation and emission of pollutants such as dioxins, heavy metals, and acidic gases during incineration can be significantly reduced, protecting the environment. The stable calorific value and controllable pollutant content can ensure the stable operation of the incinerator, reducing equipment failures and maintenance costs. By reasonably matching different types of waste, the overall utilization rate of waste can be increased, the amount of waste can be reduced, and conditions for subsequent resource utilization can be created. The formulation plan can be flexibly adjusted according to changes in waste composition and environmental protection requirements to adapt to different treatment needs. Improving incineration efficiency, reducing pollutant emissions, enhancing incineration stability, and extending equipment life can all help reduce the waste treatment cost.

[0084] The formulation principle refers to the need to simultaneously meet the following conditions:

[0085] First, the calorific value of the mixed waste is within a preset range to ensure that the incineration module can operate stably and achieve the expected combustion effect;

[0086] Second, the calorific value difference and density difference of each type of waste in the mixed waste are within a preset range to avoid uneven incineration or temperature fluctuations in the furnace due to excessive differences in calorific value and density;

[0087] Third, the VOC content, halogen content, heavy metal content, and acidic pollutant content of the mixed waste are lower than the preset thresholds to reduce the generation and emission of harmful gases during incineration and reduce the impact on the environment and human health;

[0088] Fourth, no adverse reactions occur between different types of waste in the mixed waste, that is, chemical compatibility is satisfied, to prevent the generation of toxic and harmful substances or the occurrence of safety accidents during incineration.

[0089] Analyze the chemical composition of each type of waste, predict potential reactions that may occur in the mixed waste, and consider chemical reactions that may occur under high-temperature incineration conditions, such as oxidation, reduction, decomposition, etc. When setting the constraint conditions of the formulation model according to the formulation principle, it is specified that no adverse reactions occur between different types of waste to ensure the safety and stability of the mixed waste.

[0090] After analyzing the formulation, classify each type of waste according to the obtained formulation ratio to obtain multiple combinations of mixed waste, that is, multiple configurations of waste to be incinerated. That is, each configuration of waste to be incinerated is composed of at least one type of waste combination.

[0091] During incineration treatment, there are generally multiple categories of incineration waste waiting to be processed. Before the incineration waste of each configuration category is transported into the incineration module, it needs to be sorted into individual waste piles for batch incineration. The sorting method of waste piles generally refers to compression, packing, etc. Due to the different forms and properties of the waste, the sorting time of the incineration waste of different configuration categories is different. To improve the utilization rate of the incineration module, it is necessary to achieve the interspersed incineration of waste of different configuration categories. Moreover, with the update of the analysis compatibility, the content of each type of waste in the waste to be incinerated in each configuration category has changed. Therefore, this application proposes a dynamic adjustment process, that is, after calculation, analysis and judgment, the working parameters of the incineration module are adjusted in real time, that is, the immediate application working parameters used when incinerating the waste are adjusted.

[0092] This application proposes the following dynamic adjustment process:

[0093] 104: Obtain the configuration category of the waste to be incinerated.

[0094] When the waste pile is transported into the incineration module, it is necessary to obtain the configuration category of the waste to be incinerated, such as category A, category B, category C, etc.

[0095] 105: Determine whether the configuration category of the waste to be incinerated obtained is the configuration category of the waste to be incinerated that appears for the first time in the current working cycle. If so, go to step 106; otherwise, go to step 107.

[0096] For example, when a waste pile of category A is obtained, it is judged whether category A is the configuration category that appears for the first time within the current day. Specifically, the records of the configuration categories that have appeared in the current working cycle can be queried in the central control system, and the obtained configuration category is compared with the query result to judge whether it is the first appearance.

[0097] The working cycle can be within the current day or within a week, generally not exceeding half a month, so as to avoid too large a time span, and the update of the analysis compatibility leads to the mismatch between the adjustment method output by the present invention and the actual waste situation, thereby affecting the accuracy of the adjustment of the immediate application working parameters.

[0098] 106: Extract the original set working parameters corresponding to the configuration category of the waste to be incinerated that appears for the first time from the reference operation database as the immediate application working parameters required for incinerating the waste of this configuration category; among them, the reference operation database stores the original set working parameters for the incineration module to process the waste to be incinerated in each configuration category.

[0099] The original set working parameters are the working parameters of the incineration module preset based on the previous incineration conditions and personnel operation experience.

[0100] For example, if Class A is the configuration classification that first appears within the current day's time, then the original set working parameters corresponding to Class A are extracted from the reference operation database, and the extracted original set working parameters are used as the immediate application working parameters. During subsequent incineration processing, the working parameters of the incineration module are adjusted to be consistent with the immediate application working parameters.

[0101] 107: During the same working cycle, when the waste to be incinerated of this configuration classification is obtained again, it is judged whether the recorded weight difference after the previous incineration treatment is greater than the adjustment threshold. If so, step 108 is performed; if not, step 110 is performed.

[0102] For example, when a waste pile of Class A is obtained, it is judged whether Class A is the configuration classification that first appears within the current day's time. If not, it means that the waste to be incinerated of Class A has been obtained again within the current day, and the incineration treatment of the waste to be incinerated of Class A has been performed before. At this time, a secondary judgment is required, that is, it is judged whether the recorded weight difference after the previous incineration treatment of the waste to be incinerated of Class A is greater than the adjustment threshold.

[0103] 108: If the recorded weight difference after the previous incineration treatment is greater than the adjustment threshold, the immediate application working parameters bound to this weight difference are adjusted to generate adjusted and optimized immediate application working parameters.

[0104] For example, when the waste to be incinerated of Class A was incinerated last time, the weight before incineration and the weight after incineration need to be collected, and then the difference is calculated. This weight difference indicates the weight reduction of the waste caused by the incineration operation. If this weight difference is large, specifically greater than the adjustment threshold, it means that the immediate application working parameters used during the previous incineration treatment of the waste to be incinerated of Class A are not accurate enough, resulting in the waste combustion degree not meeting the standard. It is necessary to adjust the immediate application working parameters to generate adjusted and optimized immediate application working parameters, such as increasing the combustion temperature, increasing the combustion time, and increasing the turning frequency of the turning mechanism according to the preset increase step.

[0105] 109: Bind the generated adjusted and optimized immediate application working parameters to the recorded weight difference after the previous incineration treatment, and update and record them in the temporary database for the next call and comparison, as well as for use in subsequent incineration processes.

[0106] Use the adjusted and optimized immediate application working parameters as the immediate application working parameters required for incinerating the waste of this configuration classification.

[0107] 110: If the weight difference recorded after the last incineration treatment is not greater than the adjustment threshold, extract the last recorded immediate application working parameters corresponding to the waste to be incinerated of this configuration classification from the temporary database as the immediate application working parameters required for incinerating the waste of this configuration classification.

[0108] For example, when incinerating the waste to be incinerated of Class A last time, it is necessary to collect the weight before incineration and the weight after incineration, and then calculate the difference. This weight difference indicates the weight reduction of the waste caused by the incineration operation. If this weight difference is not greater than the adjustment threshold, it means that the immediate application working parameters used for incinerating the waste to be incinerated of Class A last time meet the requirements, and the immediate application working parameters used last time can still be adopted this time.

[0109] 111: Incinerate the waste to be incinerated of the current configuration classification using the immediate application working parameters, measure the weight of the waste before and after incineration and calculate the weight difference, bind the weight difference with the adopted immediate application working parameters, and record and store them in the temporary database.

[0110] 112: After the end of the current working cycle, obtain all the immediate application working parameters adopted by the waste to be incinerated of each configuration classification in the temporary database, and record and store them in the reference operation database for personnel to refer to later. For example, personnel can modify the original set working parameters based on the data recorded in this cycle.

[0111] 113: Empty the temporary database to facilitate the next processing flow.

[0112] By setting a reasonable working cycle and making dynamic adjustments within the same working cycle, it can better adapt to the changes in the waste generation quantity and properties, ensure that the incineration treatment fits the actual waste situation, reduce the risk that the adjustment method does not match the actual waste situation caused by the analysis of compatibility updates, and thus improve the accuracy of adjusting the immediate application working parameters.

[0113] By obtaining the waste configuration classification information in real time, evaluating the incineration effect (such as the weight difference) and dynamically adjusting the incineration parameters, it can ensure that the incineration treatment is always carried out in the best state, improve the incineration efficiency, and the dynamic adjustment process can flexibly respond to the treatment requirements of waste of different configuration classifications and the irregular updates of the analysis of compatibility, realize the cross-incineration of waste, and maximize the utilization rate of the incineration module.

[0114] By binding and adjusting the weight difference with the immediate application working parameters, it is possible to ensure that the waste combustion degree reaches the expected standard, improve the incineration quality, reduce secondary pollution, adjust the parameters based on the actual incineration data, and improve the scientificity and accuracy of decision-making. The technical solution combining the working cycle setting and dynamic adjustment has significant advantages in improving incineration efficiency, quality, flexibility, environmental protection performance, etc., and at the same time realizes data-driven decision-making and continuous improvement, providing an advanced solution for the field of waste incineration treatment.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
