[0003] In the treatment technology of domestic waste, incineration power generation is the mainstream treatment method, accounting for more than 50% of the world. Its basic process is to convert waste into ash and flue gas through high-temperature combustion, thereby reducing the volume of waste, and recover the heat in the flue gas through the boiler to realize the resource utilization of waste. However, urban waste comes from a wide range of sources, including but not limited to plastics, glass, soil, paper, metal, kitchen waste, etc. In places where the collection link is not sound, there are complex and varied types, and the proportion of various types is unstable, which leads to fluctuations in calorific value and pollutant emissions during waste incineration, seriously affecting the efficiency and environmental protection of incineration treatment.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The present invention provides a control method, device, control equipment, medium and product of a garbage incineration system, which are respectively described below.

[0033] Before presenting the embodiments, the waste incineration system is introduced first.

[0034] like Figure 1 As shown, the garbage incineration system 10 includes a garbage grab crane 100 and a recovery furnace 200. The garbage grab crane 100 is used to grab the garbage in the garbage pit 20 and bring it to the recovery furnace 200 for incineration. The incineration of garbage in the recovery furnace 200 includes three stages: drying, burning, and burning. In addition, in the specific process of recycling garbage by the recovery furnace 200: a large amount of high-temperature flue gas generated after the garbage is burned is heat exchanged to heat the liquid medium to generate superheated steam, and the superheated steam enters the steam turbine generator set to generate electricity.

[0035] based on Figure 1 The waste incineration system 10 in the embodiment of the present invention is as follows: Figure 2 As shown, the control method of the waste incineration system includes: S201, constructing a mapping model based on historical operation data of the waste incineration system; the mapping model is a model representing the mapping relationship between the component concentration and calorific value of the flue gas outlet of the recovery furnace and the garbage grabbing position in the garbage pit; S202, determining the target flue gas outlet component concentration and target calorific value of the waste incineration system within a preset operating time; S203, determining the target grabbing position of the garbage grab crane for the next grabbing based on the target flue gas outlet component concentration, the target calorific value and the mapping model.

[0036] Among them, calorific value refers to the heat released by the combustion of unit fuel.

[0037] It should be noted that the target grabbing position refers to the grabbing position that matches the target flue gas outlet component concentration and target calorific value, so as to ensure that the next time the garbage is grabbed, the concentration and calorific value of the target flue gas outlet are not much different during incineration, thereby reducing the concentration fluctuation of pollutant emissions and ensuring the environmental protection of the garbage incineration system.

[0038] Among them, the preset running time can be set or adjusted according to actual conditions.

[0039] In a specific embodiment of the present invention, the preset running time is 1 hour.

[0040] It should be understood that the model structure of the mapping model can be any deep learning network structure that can accurately characterize the mapping relationship between the smoke outlet component concentration, calorific value and the garbage grabbing position in the garbage pit.

[0041] It should also be understood that the construction of the mapping model should include training, testing and verification processes, and the larger the sample size, the more accurate the constructed mapping model. Therefore, in a specific embodiment of the present invention, the time span of the historical operation data should be greater than the preset time length.

[0042] Among them, the preset duration can be set or adjusted according to the actual application scenario. Specifically, the preset duration is 3 months.

[0043] It should also be noted that the concentration of flue gas outlet components includes but is not limited to sulfur dioxide concentration and hydrogen chloride concentration.

[0044] Compared with the prior art, the control method of the garbage incineration system provided by the embodiment of the present invention constructs a mapping model based on the historical operation data of the garbage incineration system. Through the mapping model, the target grabbing position of the garbage grabbing bucket for grabbing the garbage next time can be obtained according to the determined target flue gas outlet component concentration and target calorific value. The intelligent determination of the grabbing position can make the garbage grabbed and put into the recovery furnace meet the calorific value requirements during the incineration process, ensure the thermal load of the garbage incineration system is stable, and thus improve the incineration efficiency. In addition, the intelligent determination of the grabbing position can make the flue gas outlet component concentration of the garbage meet the requirements during the incineration process, avoid pollutant emissions exceeding the limit, and ensure the environmental protection of the garbage incineration system during the garbage incineration process. In other words, the embodiment of the present invention can eliminate the technical problems of low incineration efficiency and poor environmental protection caused by uneven garbage input or feeding through the intelligent determination of the grabbing position, so that the garbage put into the recovery furnace has a higher incineration efficiency and better environmental protection during the incineration process.

[0045] Since the calorific value and the smoke outlet component concentration are related to factors such as the type of garbage, the position coordinate data alone cannot represent these factors. Therefore, in order to realize the mapping relationship between the smoke outlet component concentration, the calorific value and the grabbing position, in some embodiments of the present invention, the historical operation data includes the smoke outlet component concentration, the calorific value and the visual information of each garbage area in the garbage pit, and the visual information includes the visual feature information and the spatial coordinate information; Figure 3 As shown, step S201 includes: S301, constructing a first correspondence between the smoke outlet component concentration, calorific value and visual feature information; S302, constructing a second correspondence between visual feature information and spatial coordinate information; S303: Construct a mapping model based on the first corresponding relationship and the second corresponding relationship.

[0046] The embodiment of the present invention uses visual feature information as a bridge between the smoke outlet component concentration, calorific value and spatial coordinate information, and uses visual feature information to represent the features of different positions, thereby associating the features with the coordinate position and the smoke outlet component concentration and calorific value, thereby achieving the purpose of determining the spatial position through the smoke outlet component concentration and calorific value, that is, achieving the determination of the target capture position.

[0047] It can be seen from the above description that the accuracy of the visual feature information is crucial to the accurate determination of the target grasping position. Therefore, in some embodiments of the present invention, the historical operation data includes the RGB image data and the laser reflectivity data of each garbage area, and before step S201, it also includes: splicing the RGB image data and the laser reflectivity data to obtain garbage spliced ​​data; The first corresponding relationship in step S301 is the relationship between the smoke outlet component concentration, calorific value and garbage splicing data, that is, the visual feature information is the garbage splicing data.

[0048] The embodiment of the present invention uses junk splicing data obtained by splicing RGB image data and laser reflection data as visual feature information, which can increase the amount of information in the visual feature information and further ensure the accuracy of the determined target capture position.

[0049] In a specific embodiment of the present invention, the RGB image data includes data of three channels, namely, red, green and blue, and the garbage stitching image includes RGB data of three channels and laser reflectivity data of one channel, namely, stitching data of four channels.

[0050] In a specific embodiment of the present invention, the RGB image data and the laser reflection data are obtained as follows: Figure 1 As shown, the image is acquired through an image monitor 30 and a laser radar 40 arranged in the garbage pit 20 , and the image monitor 30 and the laser radar 40 are respectively arranged on the opposite walls of the garbage pit 20 .

[0051] Furthermore, the outlet component concentration of the flue gas is obtained by monitoring the outlet flue gas component concentration monitor 50 disposed at the outlet of the recovery furnace 200 .

[0052] Because the waste incineration system is controlled based on the calorific value and the concentration of the components at the flue gas outlet when incinerating the waste, that is, the target grabbing position is determined based on the parameters of the two dimensions of calorific value and the concentration of the components at the flue gas outlet.

[0053] Therefore, in order to simplify the model structure of the mapping model and accurately determine the target grabbing position, in some embodiments of the present invention, the mapping model includes a first mapping model and a second mapping model, the first mapping model is a model representing the mapping relationship between the smoke outlet component concentration and the garbage grabbing position, and the second mapping model is a model representing the mapping relationship between the calorific value and the garbage grabbing position; then Figure 4 As shown, step S203 includes: S401, determining a plurality of initial grab positions in the garbage pit; S402, inputting each initial grabbing position into the first mapping model and the second mapping model respectively to obtain the initial smoke outlet component concentration and initial calorific value; S403 , determining a target grabbing position among a plurality of initial grabbing positions based on the initial smoke outlet component concentration, the initial calorific value, the target smoke outlet component concentration, and the target calorific value.

[0054] The embodiment of the present invention sets a mapping model including a first mapping model and a second mapping model. The first mapping model is only used to determine the smoke outlet component concentration, and the second mapping model is only used to determine the calorific value. This simplifies the model complexity of the first mapping model and the second mapping model, thereby improving the accuracy of the first mapping model and the second mapping model, that is, improving the accuracy of the obtained initial smoke outlet component concentration and initial calorific value, thereby accurately determining the target grasping position.

[0055] In some embodiments of the present invention, Figure 5 As shown, step S401 includes: S501, dividing the garbage pit into a plurality of original grabbing positions within a preset range; S502: Clustering multiple original grabbing positions based on visual feature information of each original grabbing position and the grabbing range of the garbage grab crane to obtain multiple initial grabbing positions.

[0056] The embodiment of the present invention determines the initial grabbing position based on visual feature information, thereby ensuring that the visual feature information of garbage at the same initial grabbing position is not much different, that is, the performance of garbage at the same initial grabbing position when burning is not much different, so as to ensure that the emission of flue gas pollutants during garbage combustion fluctuates less, thereby ensuring its environmental protection.

[0057] Furthermore, the embodiment of the present invention uses the grabbing range of the garbage grab crane as a constraint condition when determining the initial grabbing position, thereby ensuring that the garbage grab crane can grab the garbage at an initial grabbing position and avoid exceeding the grabbing range of the garbage grab crane.

[0058] Specifically, step S501 is: dividing the garbage pit into a plurality of original grabbing positions with an area within a preset range based on a preset number of rows and columns.

[0059] The clustering algorithm in step S502 is the K-Means clustering algorithm.

[0060] In some embodiments of the present invention, Figure 6 As shown, step S403 includes: S601, determining the similarity between the initial flue gas outlet component concentration, initial calorific value and the target flue gas outlet component concentration, target calorific value; S602: The initial grabbing position corresponding to the initial flue gas outlet component concentration and initial calorific value with the highest similarity is used as the target grabbing position.

[0061] The embodiment of the present invention takes the target smoke outlet component concentration and the target calorific value as the target, and takes the initial grabbing position that is most similar to the target smoke outlet component concentration and the target calorific value among multiple initial grabbing positions as the target grabbing position, so that the grabbed garbage meets the calorific value and smoke outlet component concentration requirements.

[0062] In a specific embodiment of the present invention, Figure 7 As shown, step S601 includes: S701, constructing initial two-dimensional coordinate points based on initial flue gas outlet component concentration and initial calorific value; S702, constructing a target two-dimensional coordinate point based on the target flue gas outlet component concentration and the target calorific value; S703: Determine the Euclidean distance between the initial two-dimensional coordinate point and the target two-dimensional coordinate point, and use the Euclidean distance as the similarity.

[0063] Specifically, the initial flue gas outlet component concentration is denoted as MS i , the initial calorific value is PI i , the target flue gas outlet component concentration is MS, the target calorific value is PI, then the initial two-dimensional coordinate point is (MS i , P.I. i ), the target two-dimensional coordinate point is (MS, PI), and the calculation formula of the Euclidean distance is:

[0064] In another specific embodiment of the present invention, Figure 8 As shown, step S601 includes: S801, obtaining weight distribution of flue gas outlet component concentration and calorific value; S802, determining an initial weighted value based on weight distribution, initial flue gas outlet component concentration and initial calorific value; S803, determining a target weighted value based on weight distribution, target flue gas outlet component concentration, and target calorific value; S804: Taking the difference between the initial weighted value and the target weighted value as the similarity.

[0065] Specifically, the similarity for:

[0066] In the formula, is the weight of the component concentration at the flue gas outlet.

[0067] The embodiment of the present invention provides two methods for calculating similarity, which improves the diversity and redundancy of similarity calculation methods. The two methods can be selected according to actual application scenarios.

[0068] Since the combustion of garbage is a dynamic process, its calorific value and the concentration of smoke outlet components are dynamically changing processes. In order to accurately determine the target smoke outlet component concentration and target calorific value, in some embodiments of the present invention, such as Fig. 9 As shown, step S202 includes: S901, obtaining the average value of the main steam flow rate, the average value of the temperature, and the average value of the component concentration at the flue gas outlet of the waste incineration system within the preset operating time; S902, determining a target flow condition based on a main steam flow average, a temperature average, and a preset flow condition category range; S903, determining a target concentration condition based on the mean value of the component concentration at the flue gas outlet and a preset concentration condition category range; S904. Obtain a target calorific value corresponding to a target flow rate condition and a target flue gas outlet component concentration corresponding to a target concentration condition.

[0069] The embodiment of the present invention uses the mean value of the main steam flow rate, the mean value of the temperature, and the mean value of the component concentration at the flue gas outlet within the preset operating time as the basis for determining the target calorific value and the target component concentration at the flue gas outlet, and uses the mean value to replace the value that fluctuates continuously over a period of time, which is simple and accurate. In addition, the embodiment of the present invention determines the target component concentration at the flue gas outlet and the target calorific value based on the calibrated concentration condition and flow condition, thereby improving the representativeness and accuracy of the target component concentration at the flue gas outlet and the target calorific value.

[0070] It should be noted that different concentration conditions and different flow conditions can be established based on historical operating data, and the flue gas outlet component concentrations corresponding to different concentration conditions and the calorific values ​​corresponding to different flow conditions can be determined to ensure the adaptability and accuracy of the calorific value and flue gas outlet component concentration to the actual operating scenario.

[0071] In a specific embodiment of the present invention, Figure 1 As shown, the main steam flow average value and the temperature average value in step S901 can be obtained based on the main steam flow and temperature detector 60 set on the recovery furnace 200.

[0072] In some embodiments of the present invention, Figure 1 As shown, the recovery furnace 200 includes a mechanical grate furnace 210 and a waste heat boiler 220. The mechanical grate furnace 210 is used to incinerate garbage to obtain thermal energy, and the waste heat boiler 220 is used to generate high-temperature steam based on thermal energy. The recovery furnace 200 also includes a primary fan 230 connected to the mechanical grate furnace 210 and a secondary fan 240 connected to the waste heat boiler 220.

[0073] The primary fan 230 and the secondary fan 240 are used to supply primary air and secondary air to the mechanical grate furnace 210 and the waste heat boiler 220 respectively. The function of the primary air is to dry and assist combustion of the mechanical grate furnace 210, and the function of the secondary air is to enhance combustion in the combustion zone of the waste heat boiler 220.

[0074] From the above description, it can be seen that the primary air and the secondary air are crucial to the garbage combustion process. On the basis of accurately determining the target grabbing position, in order to further improve the garbage combustion efficiency, in some embodiments of the present invention, such as Fig.10 As shown, the control method of the waste incineration system also includes: S1001, obtaining multiple boundary conditions of fan frequencies of a primary fan and a secondary fan; S1002. Determine the fan frequencies of the primary fan and the secondary fan based on a particle swarm optimization algorithm and multiple boundary conditions; S1003. Adjust the frequency of the primary fan and the secondary fan based on the fan frequency.

[0075] The embodiment of the present invention can ensure the rationality of the fan frequency by adjusting the fan frequency of the primary fan and the secondary fan based on multiple boundary conditions, so as to improve the combustion efficiency of garbage.

[0076] In a specific embodiment of the present invention, the boundary conditions are: The furnace outlet temperature of the waste heat boiler is greater than or equal to 950°C and less than or equal to 1100°C; The carbon monoxide emission concentration in the flue gas outlet of the waste heat boiler is less than or equal to 50mg / Nm 3 ; The fan frequency of the primary fan and the secondary fan is less than or equal to 50 Hz.

[0077] Since the combustion of garbage is a fast and dynamic process, the adjustment of the fan frequency of the primary fan and the secondary fan should also be constantly changing, that is, it needs to be adjusted according to the progress of the combustion process.

[0078] In a specific embodiment of the present invention, the frequency of adjusting the fan frequency is once every 5 minutes.

[0083] Among them, the outlet of the flue gas purification component in step S1101 is the chimney outlet.

[0084] The embodiment of the present invention controls the concentration of flue gas components discharged into the atmosphere by adjusting the flow rate of slaked lime released from the slaked lime storage tank, thereby ensuring the environmental friendliness of the waste incineration system 10. At the same time, it avoids excessive input of slaked lime and reduces costs.

[0085] Since the waste incineration system 10 is a continuous and long-term operating system, in order to ensure the accuracy of its control, in some embodiments of the present invention, the control method of the waste incineration system further includes: The mapping model is updated based on the continuous operating data of the waste incineration system.

[0086] The embodiment of the present invention can ensure the real-time and accuracy of the mapping model by updating the mapping model based on the continuous operation data, thereby improving the accurate control of the waste incineration system in various time periods.

[0087] Specifically, the specific means for updating the mapping model may be: updating the mapping model based on the data of the three or four months of operation every three or four months of operation.

[0088] In another specific embodiment of the present invention, the mapping model may be updated by: rolling updating the mapping model based on continuous operation data, specifically, the mapping model used on August 20, 2024 is constructed based on the operation data from June 19, 2024 to August 19, 2024, and the mapping model used on August 21, 2024 is constructed based on the operation data from June 20, 2024 to August 20, 2024, to ensure the real-time and accuracy of the mapping model.
