Description

Technical Field

[0001] This invention relates to the field of waste liquid incinerator technology, specifically to an intelligent monitoring system and process for a salt and sulfur-containing waste liquid incinerator. Background Technology

[0002] A saline- and sulfur-containing waste liquid incinerator is an environmentally friendly device specifically designed for treating saline- and sulfur-containing waste liquids. Through high-temperature incineration, it decomposes harmful substances in these highly polluting and difficult-to-treat waste liquids, enabling them to meet environmental emission standards. It features high treatment efficiency and strong stability, playing a vital role in waste liquid treatment in industries such as petrochemicals.

[0003] Patent application number 201811290782.1 discloses a combustion control system for a sulfur-containing waste liquid incinerator, which includes an incinerator; it also includes a sulfur-containing waste liquid pipeline, a compressed air pipeline, a coke oven gas pipeline, a combustion air pipeline, and a control unit, all connected to the incinerator. The sulfur-containing waste liquid pipeline includes, in sequence, a waste liquid flow meter, a waste liquid regulating valve, a waste liquid quick-cut-off valve, and a waste liquid spray gun; the compressed air pipeline includes, in sequence, a compressed air flow meter and a compressed air regulating valve, with the output end of the compressed air regulating valve connected to the waste liquid spray gun; the coke oven gas pipeline includes a coke oven gas flow meter... The incinerator includes a flow meter, a coke oven regulating valve, a first coke oven quick-cut-off valve, a second coke oven quick-cut-off valve, and an ammonia supply section connected to the coke oven gas pipeline; the combustion air pipeline includes a combustion regulating valve; the incinerator includes a furnace body and a burner assembly installed on the furnace body, the burner assembly including several flame detectors, igniters, temperature sensors, and oxygen detection alarms; the output terminal of the control unit is electrically connected to the control terminals of the waste liquid flow meter, the waste liquid regulating valve, the compressed air flow meter, the compressed air regulating valve, the coke oven flow meter, the coke oven regulating valve, and the combustion regulating valve.

[0004] The application aims to address the problem that "the high temperature and the presence of a large amount of combustible material inside the furnace during the incineration process can easily lead to major safety accidents if key parameters fluctuate."

[0005] However, the key to the operation and monitoring of saline and sulfur-containing waste liquid incinerators lies in the monitoring of their furnace temperature. Most existing technologies have only one monitoring point, and the monitoring results are one-sided, making it impossible to accurately and comprehensively monitor the furnace temperature of saline and sulfur-containing waste liquid incinerators.

[0006] To address this, we propose an intelligent monitoring system and process for incinerators containing salt and sulfur waste liquid. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an intelligent monitoring system and process for a salt and sulfur-containing waste liquid incinerator, which solves the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] In the first aspect, an intelligent monitoring system for a saline and sulfur-containing waste liquid incinerator includes: a sensing layer, a modeling layer, and an analysis layer;

[0010] Temperature information of the furnace surface of the incinerator is collected in real time by the sensing layer. After being summarized in the sensing layer, the temperature information is sent to the modeling layer in real time. The modeling layer receives the temperature information fed back by the sensing layer and builds a furnace temperature model based on the temperature information. The analysis layer further receives the furnace temperature model built in the modeling layer and analyzes whether the internal temperature of the incinerator furnace is uniform based on the furnace temperature model and the waste liquid incineration parameters.

[0011] The modeling layer includes a modeling module, a retrieval module, and a rendering module. The modeling module is used to upload the structural parameters of the incinerator furnace and construct a three-dimensional model of the incinerator furnace based on the structural parameters. The retrieval module is used to retrieve the surface temperature information of the incinerator furnace collected in real time from the perception layer. The rendering module is used to receive the three-dimensional model of the incinerator furnace constructed in the modeling module and the surface temperature information of the incinerator furnace retrieved in the retrieval module, and render the surface of the three-dimensional model of the incinerator furnace based on the surface temperature information of the incinerator furnace.

[0012] Before rendering the surface of the three-dimensional model of the incinerator furnace, the rendering module first divides the surface of the three-dimensional model of the incinerator furnace. The number of divisions is the same as the number of sensing modules, and the size of each division is equal. The coordinates of any point on each division are known.

[0013] Further referencing the coordinates of the temperature information markers, determine the segmentation plane to which the coordinates of the temperature information markers belong. Bind the segmentation planes to the temperature information one by one, select any color as the rendering target color, set the ratio of rendering saturation to distance, and further segment the segmentation planes. The segmentation result is recorded as a sub-segmentation plane matrix. The sub-segmentation plane at the center of the matrix applies the rendering target color saturation of 100%, and the sub-segmentation planes adjacent to the sub-segmentation plane at the center of the matrix are rendered based on the ratio of rendering saturation to distance.

[0014] Furthermore, the sensing layer includes a sensing module, a receiving module, and an alarm module. The sensing module is used to sense the surface temperature information of the incinerator furnace in real time. The receiving module is used to receive the surface temperature information of the incinerator furnace sensed by the sensing module and summarize the temperature information. The alarm module is used to set the safe judgment range of the working state of the incinerator furnace and compare the safe judgment range of the working state of the incinerator furnace with the temperature information summarized by the receiving module to determine whether the working state of the incinerator furnace is safe.

[0015] The sensing module integrates temperature sensors and consists of several groups of sensors evenly distributed on the surface of the incinerator furnace. The spacing between adjacent sensing modules is equal. The receiving module performs the following operations to summarize the temperature information: identify the sensing module from which the temperature information originates, obtain the position coordinates of each sensing module on the surface of the incinerator furnace, mark the position coordinates corresponding to the sensing module from which the temperature information originates on the temperature information, and package all the temperature information marked with position coordinates to obtain a temperature information data packet.

[0016] Furthermore, when the sensing modules are deployed on the surface of the incinerator furnace, the following conditions must be met: the distance between adjacent sensing modules is no greater than L / 20, where L is the length of the incinerator furnace.

[0017] The safety judgment range for the incinerator furnace working status set in the alarm module is user-defined on the system side. The alarm module is integrated with a speaker and a control unit. The speaker stores user-defined alarm audio. The alarm module detects:

[0018] When the temperature information sensed by any two or more adjacent sensor modules does not conform to the safe judgment range of the working state of the incinerator furnace, or when the number of temperature information that does not conform to the safe judgment range of the working state of the incinerator furnace exceeds 1 / 100 of the total number of temperature information, the alarm audio is played by the speaker, the control unit controls all valves on the incinerator to close, and then controls the incinerator to stop running.

[0019] Furthermore, when the alarm module determines that two or more temperature readings do not fall within the safe operating range of the incinerator furnace, it simultaneously assesses the operational risk of the incinerator. The assessment logic is as follows:

[0020]

[0021] Where: f is the incinerator operation risk value; n is the number of temperature information that does not meet the safety judgment range of the incinerator furnace working state; d(i,i+1) is the distance between the sensing module from which the i-th temperature information and the (i+1)-th temperature information are located on the surface of the incinerator furnace; T iLet be the temperature value represented by the i-th temperature information; min G is the value with the smallest difference from the temperature information among the two endpoints of the safe judgment interval of the working state of the incinerator furnace.

[0022] in, Indicates to The higher the average value of the incinerator's operating risk value f, the higher the operating risk of the incinerator, and vice versa.

[0023] Furthermore, the three-dimensional spatial scale of the incinerator furnace 3D model constructed by the modeling module is the same as the spatial scale of the incinerator furnace surface coordinates where the temperature information source sensor module is located.

[0024] The temperature information retrieved by the retrieval module is the temperature information data packet generated in the sensing layer;

[0025] The saturation of adjacent edge sub-segmentation surfaces at the edge positions of each of the aforementioned segmentation surfaces is adjusted to half the saturation of the two sub-segmentation surfaces.

[0026] Furthermore, the dividing surfaces are subject to the rule that each sub-dividing surface is equal in size and shape when the dividing operation is performed;

[0027] When the segmentation operation is performed, the number of sub-segmentation surfaces obtained from the segmentation follows the following order:

[0028]

[0029] In the formula: x is the number of sub-segments obtained from the segmentation; x0 is the base number of sub-segments; Q norr (t) represents the amount of waste liquid effectively treated up to time t; Δt is a user-defined time interval used to determine the incinerator's combustion efficiency; Q all σ(t) represents the total amount of waste liquid added up to time t; σ(t) represents the average standard deviation of the furnace surface temperature information within the time period [(t-Δt), (t+Δt)] around time t; max R(t) represents the maximum standard deviation; R(t) represents the cumulative number of critical components replaced by the incinerator up to time t; T represents the design service life of the incinerator; W(t) represents the time node weighting function.

[0030] In the above formula, the left side of the approximate equality sign is rounded up, x0≥9, and t is the time from the start-up of the incinerator to the current operation of the sensing module. This indicates the criticality of the incinerator's operation task relative to time point t when the incinerator has been running for t.

[0031] α is a constant greater than zero, and [t1,t2] represents the critical operating period of the incinerator as defined by the user on the system side.

[0032] Furthermore, the analysis layer includes a creation module, an analysis module, and a judgment module. The creation module is used to create a plane on the vertical central axis of the rendered 3D model of the incinerator furnace, and to cut the 3D model of the incinerator furnace based on the created plane to obtain two sub-incinerator furnace 3D models. The analysis module is used to receive the two sub-incinerator furnace 3D models obtained by the creation module, and to analyze the rendering plane symmetry of the two sub-incinerator furnace 3D models. The judgment module is used to obtain the rendering plane symmetry analysis results of the two sub-incinerator furnace 3D models in the analysis module, and to determine whether the internal temperature of the incinerator furnace is uniform based on the analysis results.

[0033] The creation and analysis modules are defined by the system user for the number of consecutive runs, and the number of consecutive runs is no less than two. The higher the temperature accuracy requirement of the incinerator furnace, the more consecutive running parameters are set, and vice versa. The judgment module has a balance judgment threshold that is customized by the system user. If the average value of the results of the continuous operation of the analysis module is greater than the balance judgment threshold, the internal temperature of the incinerator furnace is judged to be balanced; otherwise, the internal temperature of the incinerator furnace is judged to be unbalanced.

[0034] During the continuous operation of the creation module, the planes created each time do not overlap.

[0035] Furthermore, the rendering plane symmetry analysis logic for the two sub-incinerator furnace 3D models in the analysis module is as follows:

[0036]

[0037] In the formula: S represents the symmetry of the rendering surfaces of the two sub-incinerator furnace 3D models; W and H represent the width and height of the rendering surfaces of the sub-incinerator furnace 3D models; D(a,b) represents the difference in grayscale values ​​between pixel (a,b) in the rendering surface of one sub-incinerator furnace 3D model and the symmetrical point in the rendering surface of the other sub-incinerator furnace 3D model; I(a,b) represents the grayscale value of pixel (a,b) after the rendering surface of the sub-incinerator furnace 3D model containing pixel (a,b) is converted into a grayscale image.

[0038] Wherein, the closer S is to 1, the higher the symmetry of the rendering surface of the two sub-incinerator furnace 3D model, and the closer S is to 0, the lower the symmetry of the rendering surface of the two sub-incinerator furnace 3D model.

[0039] Furthermore, the modeling module is interconnected with an alarm module via a wireless network, the alarm module is interconnected with a receiving module and a sensing module via a wireless network, the modeling module is interconnected with a retrieval module and a rendering module via a wireless network, the rendering module is interconnected with a creation module via a wireless network, and the creation module is interconnected with a determination module via a wireless network.

[0040] Secondly, an intelligent monitoring process for a saline and sulfur-containing waste liquid incinerator includes:

[0041] Temperature sensors are uniformly deployed on the surface of the incinerator furnace to detect the surface temperature of the incinerator furnace in real time.

[0042] A three-dimensional model of the incinerator furnace is constructed based on the furnace structure parameters. The surface of the three-dimensional model of the incinerator furnace is segmented so that the number of segments is equal to the number of temperature sensors deployed on the furnace surface.

[0043] Select the surface rendering color of the 3D model of the incinerator furnace, set the ratio of rendering saturation to distance, and further divide the segmented surface to obtain several sub-segmented surfaces. Based on the distance of each sub-segmented surface and the set ratio of rendering saturation to distance, render each sub-segmented surface in the segmented surface, so that the rendering saturation of the sub-segmented surface at the center position is 100%.

[0044] A plane is created on the central axis of the rendered 3D model of the incinerator furnace. The 3D model of the incinerator furnace is then cut based on the created plane to obtain two sub-incinerator furnace 3D models. The symmetry of the surface color distribution of the two sub-incinerator furnace 3D models is then analyzed.

[0045] The symmetry analysis results are used to determine whether the temperature inside the incinerator furnace is uniform.

[0046] Compared with known public technologies, the technical solution provided by this invention has the following advantages:

[0047] Beneficial effects:

[0048] This invention provides an intelligent monitoring system for a saline and sulfur-containing waste incinerator. During operation, the system collects temperature information from the furnace surface using temperature sensors deployed on the furnace chamber. Based on the collected temperature information, it determines the safety of the furnace chamber's operating status. Furthermore, it constructs a three-dimensional model of the furnace chamber and renders the surface of this model using the temperature information. The system then analyzes the symmetry of the color distribution on the model surface based on the rendering results, ultimately determining whether the internal temperature of the furnace chamber is balanced. This system assists furnace operators in quickly and in real-time monitoring the furnace chamber's temperature balance, providing intelligent monitoring for safe operation.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0055] The present invention will be further described below with reference to embodiments.

[0056] Example 1:

[0057] This embodiment provides an intelligent monitoring system for a saline and sulfur-containing waste liquid incinerator, such as... Figure 1 As shown, it includes: a perception layer, a modeling layer, and an analysis layer;

[0058] Temperature information of the furnace surface of the incinerator is collected in real time by the sensing layer. After being summarized in the sensing layer, the temperature information is sent to the modeling layer in real time. The modeling layer receives the temperature information fed back by the sensing layer and builds a furnace temperature model based on the temperature information. The analysis layer further receives the furnace temperature model built in the modeling layer and analyzes whether the internal temperature of the incinerator furnace is uniform based on the furnace temperature model and the waste liquid incineration parameters.

[0059] The sensing layer includes a sensing module, a receiving module, and an alarm module. The sensing module is used to sense the surface temperature information of the incinerator furnace in real time. The receiving module is used to receive the surface temperature information of the incinerator furnace sensed by the sensing module and summarize the temperature information. The alarm module is used to set the safe judgment range of the working state of the incinerator furnace and compare the safe judgment range of the working state of the incinerator furnace with the temperature information summarized by the receiving module to determine whether the working state of the incinerator furnace is safe.

[0060] The sensing module integrates temperature sensors and consists of several groups of sensors evenly distributed on the surface of the incinerator furnace. The spacing between adjacent sensing modules is equal. The receiving module performs the following operations to summarize the temperature information: identify the sensing module from which the temperature information originates, obtain the position coordinates of each sensing module on the surface of the incinerator furnace, mark the position coordinates corresponding to the sensing module from which the temperature information originates on the temperature information, and package all the temperature information marked with position coordinates to obtain a temperature information data packet.

[0061] When sensor modules are deployed on the surface of the incinerator furnace, the following rule applies: the distance between adjacent sensor modules shall not exceed L / 20, where L is the length of the incinerator furnace.

[0062] The safe operating status judgment range of the incinerator furnace set in the alarm module is user-defined on the system side. The alarm module is integrated with a speaker and control unit. The speaker stores alarm audio values ​​defined by the user on the system side. The alarm module detects the following:

[0063] When the temperature information sensed by any two or more adjacent sensor modules does not meet the safe judgment range of the working state of the incinerator furnace, or when the temperature information that does not meet the safe judgment range of the working state of the incinerator furnace exceeds 1 / 100 of the total number of temperature information, the alarm audio is played by the speaker, the control unit controls all valves on the incinerator to close, and then controls the incinerator to stop running.

[0064] When the alarm module detects that two or more temperature readings do not fall within the safe operating range of the incinerator furnace, it simultaneously assesses the operational risk of the incinerator. The assessment logic is as follows:

[0065]

[0066] Where: f is the incinerator operation risk value; n is the number of temperature information that does not meet the safety judgment range of the incinerator furnace working state; d(i,i+1) is the distance between the sensing module from which the i-th temperature information and the (i+1)-th temperature information are located on the surface of the incinerator furnace; T i Let be the temperature value represented by the i-th temperature information; min G is the value with the smallest difference from the temperature information among the two endpoints of the safe judgment interval of the working state of the incinerator furnace.

[0067] in, Indicates to The larger the average value f of the incinerator operation risk, the higher the incinerator operation risk, and vice versa.

[0068] By digitally calculating the operational risks of the incinerator using the above formula, in the implementation scenario of this system, the calculation results can assist incinerator operators in combining the analysis results of whether the internal temperature of the incinerator furnace is uniform, and to carry out more appropriate safety management of the incinerator, or apply the calculation results of the above formula to the analysis process of whether the internal temperature of the incinerator furnace is uniform, so as to improve the accuracy of the final analysis results of whether the internal temperature of the incinerator furnace is uniform.

[0069] The modeling layer includes a modeling module, a retrieval module, and a rendering module. The modeling module is used to upload the structural parameters of the incinerator furnace and construct a 3D model of the incinerator furnace based on the structural parameters. The retrieval module is used to retrieve the surface temperature information of the incinerator furnace collected in real time from the perception layer. The rendering module is used to receive the 3D model of the incinerator furnace constructed in the modeling module and the surface temperature information of the incinerator furnace retrieved in the retrieval module, and render the surface of the 3D model of the incinerator furnace based on the surface temperature information.

[0070] Before rendering the surface of the 3D model of the incinerator furnace, the rendering module first divides the surface of the 3D model of the incinerator furnace. The number of divisions is the same as the number of sensing modules, and the size of each division is equal. The coordinates of any point on each division are known.

[0071] Further referencing the coordinates of the temperature information markers, determine the segmentation plane to which the coordinates of the temperature information markers belong, bind the segmentation planes to the temperature information one by one, select any color as the rendering target color, set the ratio of rendering saturation to distance, further segment the segmentation planes, and record the segmentation result as a sub-segmentation plane matrix. The sub-segmentation plane at the center of the matrix applies the rendering target color saturation of 100%, and the sub-segmentation planes adjacent to the sub-segmentation plane at the center of the matrix are rendered based on the ratio of rendering saturation to distance.

[0072] When performing a segmentation operation, the sub-segments are ordered to be equal in size and shape.

[0073] When performing a segmentation operation, the number of sub-segments obtained from the segmentation follows the following rule:

[0074]

[0075] In the formula: x is the number of sub-segments obtained from the segmentation; x0 is the base number of sub-segments; Q norr(t) represents the amount of waste liquid effectively treated up to time t; Δt is a user-defined time interval used to determine the incinerator's combustion efficiency; Q all σ(t) represents the total amount of waste liquid added up to time t; σ(t) represents the average standard deviation of the furnace surface temperature information within the time period [(t-Δt), (t+Δt)] around time t; max R(t) represents the maximum standard deviation; R(t) represents the cumulative number of critical components replaced by the incinerator up to time t; T represents the design service life of the incinerator; W(t) represents the time node weighting function.

[0076] In the above formula, the left side of the approximate equality sign is rounded up, x0≥9, and t is the time from the start-up of the incinerator to the current operation of the sensing module. This indicates the criticality of the incinerator's operation task relative to time point t when the incinerator has been running for t.

[0077] α is a constant greater than zero, and [t1,t2] represents the critical operating period of the incinerator as defined by the user on the system side;

[0078] The above logical formula provides support for the further segmentation operation of the segmentation surface of the technical solution in this embodiment, ensuring that the segmentation surface is segmented based on the specified logic to obtain the sub-segmentation surface required for further operation of this solution;

[0079] The analysis layer includes a creation module, an analysis module, and a judgment module. The creation module is used to create a plane on the vertical central axis of the rendered 3D model of the incinerator furnace. Based on the created plane, the 3D model of the incinerator furnace is cut to obtain two sub-incinerator furnace 3D models. The analysis module is used to receive the two sub-incinerator furnace 3D models obtained by the creation module and analyze the rendering plane symmetry of the two sub-incinerator furnace 3D models. The judgment module is used to obtain the rendering plane symmetry analysis results of the two sub-incinerator furnace 3D models in the analysis module and determine whether the internal temperature of the incinerator furnace is uniform based on the analysis results.

[0080] The creation and analysis modules allow users on the system side to define the number of consecutive runs, with no fewer than two consecutive runs. The higher the accuracy requirement for the incinerator furnace temperature, the more consecutive run parameters are set, and vice versa. The judgment module has a user-defined equilibrium judgment threshold. If the average value of the results of the continuous operation of the analysis module is greater than the equilibrium judgment threshold, the internal temperature of the incinerator furnace is determined to be balanced; otherwise, the internal temperature of the incinerator furnace is determined to be unbalanced.

[0081] During the continuous operation of the creation module, the planes created each time do not overlap.

[0082] The symmetry analysis logic for the rendering surfaces of the two sub-incinerator furnace 3D models in the analysis module is as follows:

[0083]

[0084] In the formula: S represents the symmetry of the rendering surfaces of the two sub-incinerator furnace 3D models; W and H represent the width and height of the rendering surfaces of the sub-incinerator furnace 3D models; D(a,b) represents the difference in grayscale values ​​between pixel (a,b) in the rendering surface of one sub-incinerator furnace 3D model and the symmetrical point in the rendering surface of the other sub-incinerator furnace 3D model; I(a,b) represents the grayscale value of pixel (a,b) after the rendering surface of the sub-incinerator furnace 3D model containing pixel (a,b) is converted into a grayscale image.

[0085] Wherein, the closer S is to 1, the higher the symmetry of the rendering surface of the two sub-incinerator furnace 3D model; the closer S is to 0, the lower the symmetry of the rendering surface of the two sub-incinerator furnace 3D model.

[0086] The above logical formula further defines the analysis logic of rendering the symmetry of the three-dimensional model of the sub-incinerator furnace, thus presenting the digital calculation results to the system user and providing the system user with a clearer reference.

[0087] The modeling module is connected to the alarm module via a wireless network. The alarm module is connected to the receiving module and the sensing module via a wireless network. The modeling module is connected to the retrieval module and the rendering module via a wireless network. The rendering module is connected to the creation module via a wireless network. The creation module is connected to the judgment module via a wireless network.

[0088] In this embodiment, the sensing module continuously senses the surface temperature information of the incinerator furnace in real time. The receiving module further receives the surface temperature information of the incinerator furnace sensed by the sensing module, summarizes the temperature information, and the alarm module simultaneously sets a safe judgment range for the working state of the incinerator furnace. Based on the safe judgment range for the working state of the incinerator furnace, the module compares the summarized temperature information with the temperature information to determine whether the working state of the incinerator furnace is safe. Then, the modeling module uploads the structural parameters of the incinerator furnace and constructs a three-dimensional model of the incinerator furnace based on the structural parameters. The retrieval module retrieves the surface temperature information of the incinerator furnace collected in real time from the sensing layer, and the rendering module receives the incinerator furnace constructed in the modeling module in real time. The 3D model and the retrieved incinerator furnace surface temperature information are used to render the surface of the 3D incinerator furnace. Finally, the creation module creates a plane on the vertical central axis of the rendered 3D incinerator furnace, and cuts the 3D incinerator furnace based on the created plane to obtain two sub-incinerator furnace 3D models. The analysis module receives the two sub-incinerator furnace 3D models obtained by the creation module, analyzes the rendering plane symmetry of the two sub-incinerator furnace 3D models, and obtains the rendering plane symmetry analysis results of the two sub-incinerator furnace 3D models from the analysis module through the judgment module. Based on the analysis results, it is determined whether the internal temperature of the incinerator furnace is uniform.

[0089] Through the operation of the system in the above embodiments, full-coverage temperature monitoring is provided for the furnace of the salt and sulfur waste liquid incinerator, which helps the incinerator operator to more quickly and conveniently monitor the real-time temperature of the incinerator and manage the operation safety.

[0090] See Figure 3 As shown in the figure, based on the markings, the plane created by the creation module in the analysis layer is further illustrated. This plane is the vertical central axis constrained by the plane when it is created. The rendered 3D model of the incinerator furnace is cut based on the created plane, providing support for the symmetry analysis of the rendering plane of the 3D model of the incinerator furnace.

[0091] like Figure 1 As shown, the three-dimensional spatial scale of the incinerator furnace 3D model constructed by the modeling module is the same as the spatial scale of the incinerator furnace surface coordinates where the temperature information source sensor module is located.

[0092] The temperature information retrieved by the module is the temperature information data packet generated in the sensing layer;

[0093] The saturation of adjacent edge sub-segments at the edge of each segmentation surface is adjusted to half the saturation of the two sub-segments.

[0094] The above settings provide further operational logic and data support for the modeling layer of the system in the above embodiments, ensuring that the modeling layer operates more stably in the system.

[0095] Example 2:

[0096] At the implementation level, based on Example 1, this example refers to... Figure 2 The intelligent monitoring system for a salt and sulfur-containing waste liquid incinerator in Example 1 will be further described in detail below:

[0097] A smart monitoring process for a saline- and sulfur-containing waste liquid incinerator includes:

[0098] Temperature sensors are uniformly deployed on the surface of the incinerator furnace to detect the surface temperature of the incinerator furnace in real time.

[0099] A three-dimensional model of the incinerator furnace is constructed based on the furnace structure parameters. The surface of the three-dimensional model of the incinerator furnace is segmented so that the number of segments is equal to the number of temperature sensors deployed on the furnace surface.

[0100] Select the surface rendering color of the 3D model of the incinerator furnace, set the ratio of rendering saturation to distance, and further divide the segmented surface to obtain several sub-segmented surfaces. Based on the distance of each sub-segmented surface and the set ratio of rendering saturation to distance, render each sub-segmented surface in the segmented surface, so that the rendering saturation of the sub-segmented surface at the center position is 100%.

[0101] A plane is created on the central axis of the rendered 3D model of the incinerator furnace. The 3D model of the incinerator furnace is then cut based on the created plane to obtain two sub-incinerator furnace 3D models. The symmetry of the surface color distribution of the two sub-incinerator furnace 3D models is then analyzed.

[0102] The symmetry analysis results are used to determine whether the temperature inside the incinerator furnace is uniform.

[0103] In summary, during operation, the system in the above embodiments collects temperature information from the incinerator furnace surface using temperature sensors deployed on the furnace surface.
