Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid incinerators, and in particular to an intelligent monitoring system and process for a salt- and sulfur-containing waste liquid incinerator. Background Art

[0002] The salt- and sulfur-containing waste liquid incinerator is an environmentally friendly device specifically designed to treat salt- and sulfur-containing waste liquids. Through high-temperature incineration, it decomposes harmful substances in these highly polluting and difficult-to-treat waste liquids, ensuring they meet environmental emission standards. Its high treatment efficiency and robust stability make it a crucial component of waste liquid treatment in industries like the petrochemical industry.

[0003] The invention patent with application number 201811290782.1 discloses a combustion control system of 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 respectively connected to the incinerator, the sulfur-containing waste liquid pipeline includes a waste liquid flow meter, a waste liquid regulating valve, a waste liquid quick shut-off valve and a waste liquid spray gun in sequence; the compressed air pipeline includes a compressed air flow meter and a compressed air regulating valve in sequence, and the pipeline at the output end of the compressed air regulating valve is connected to the waste liquid spray gun; the coke oven gas pipeline includes a coke oven flow meter, a compressed air regulating valve, a combustion air pipeline and a control unit respectively connected to the incinerator, A flow meter, a coke oven regulating valve, a first coke oven quick shut-off valve, a second coke oven quick shut-off valve and an ammonia supply part connected to the coke oven gas pipeline; the combustion air pipeline includes a combustion regulating valve; the incinerator includes a furnace body, a burner assembly installed on the furnace body, and the burner assembly includes a number of flame detectors, an igniter, a temperature sensor, and an oxygen detection alarm: the output end of the control unit is electrically connected to the control end 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 solve the problem that "the high temperature and the presence of a large amount of combustible materials in the furnace during the incineration process can easily cause major safety accidents if key parameters fluctuate."

[0005] However, the key to the operation monitoring of the salt-containing and sulfur-containing waste liquid incinerator lies in its furnace temperature monitoring. Most of the existing technologies have single monitoring points and one-sided monitoring results, which cannot accurately and globally monitor the furnace temperature of the salt-containing and sulfur-containing waste liquid incinerator.

[0006] To this end, we proposed an intelligent monitoring system and process for the incinerator of salt-containing and sulfur-containing waste liquid. Summary of the Invention

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

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] In a first aspect, an intelligent monitoring system for a salt- and sulfur-containing waste liquid incinerator comprises: a perception layer, a modeling layer, and an analysis layer;

[0010] The temperature information of the incinerator's furnace surface is collected in real time by the perception layer. The temperature information is summarized in the perception layer and sent to the modeling layer in real time. The modeling layer synchronously receives the temperature information fed back by the perception 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 temperature inside the incinerator furnace is balanced 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 incinerator furnace structure parameters and build a three-dimensional model of the incinerator furnace based on the incinerator furnace structure parameters. The retrieval module is used to retrieve the incinerator furnace surface temperature information collected in real time in the perception layer. The rendering module is used to receive the incinerator furnace three-dimensional model built in the modeling module and the incinerator furnace surface temperature information retrieved in the retrieval module, and render the surface of the incinerator furnace three-dimensional model based on the incinerator furnace surface temperature information.

[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 sensor modules, the size of each division surface is equal, and the position coordinates of any point on each division surface are known;

[0013] Further refer to the position coordinates of the temperature information mark to determine the segmentation surface to which the position coordinates of the temperature information mark belong, bind the segmentation surface 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 surface. The segmentation result is recorded as a sub-segmentation surface matrix. The central sub-segmentation surface of the matrix applies the rendering target color saturation of 100%, and the sub-segmentation surfaces adjacent to the central sub-segmentation surface of the matrix are rendered based on the ratio of rendering saturation to distance.

[0014] Furthermore, the perception 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 a safety determination interval for the working state of the incinerator furnace, and compare the safety determination interval for 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] Among them, the sensor module is integrated with a temperature sensor, and the sensor module is provided in several groups. The several groups of sensor modules are evenly distributed on the surface of the incinerator furnace, and the spacing between adjacent sensor modules is equal. The receiving module summarizes the temperature information as follows: identifying the source sensor module of the temperature information, obtaining the position coordinates of each sensor module on the surface of the incinerator furnace, marking the position coordinates corresponding to the source sensor module of the temperature information on the temperature information, and packaging all the temperature information marked with the position coordinates to obtain a temperature information data packet.

[0016] Furthermore, when the sensor modules are deployed on the surface of the incinerator furnace, the following conditions are met: the distance between adjacent sensor modules is not greater than L / 20, where L is the length of the incinerator furnace;

[0017] The safety determination interval of the incinerator furnace working state set in the alarm module is customized by the system end user. The alarm module is integrated with a speaker and a control unit. The speaker stores the alarm audio customized by the system end user. The alarm module determines that:

[0018] When the temperature information sensed by any two or more adjacent sensing modules does not meet the safety judgment range of the incinerator furnace working status, or when the temperature information that does not meet the safety judgment range of the incinerator furnace working status exceeds 1 / 100 of the total number of temperature information, the alarm audio is controlled by the speaker to play, 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 information do not meet the safety determination range of the incinerator furnace working state, it simultaneously evaluates the incinerator operation risk. The evaluation logic is expressed 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 interval of the incinerator furnace working state; d(i,i+1) is the distance between the sensor module of the i-th temperature information and the i+1-th temperature information source and the incinerator furnace surface; T iis the temperature value represented by the i-th temperature information; min G is the end value with the smallest difference from the temperature information among the two end values ​​of the incinerator furnace working state safety judgment interval;

[0022] in, Express The larger the incinerator operation risk value f is, the higher the incinerator operation risk is; conversely, the lower the incinerator operation risk is.

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

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

[0025] The saturations of the edge sub-division surfaces adjacent to each other at the edge of each division surface are adjusted to half of the saturations of the two sub-division surfaces.

[0026] Furthermore, the splitting surface is obeyed when performing the splitting operation, and the size and shape of each sub-split surface are equal;

[0027] When the splitting surface is split, the number of sub-split surfaces obtained by splitting is:

[0028]

[0029] Where: x is the number of sub-division surfaces obtained by segmentation; x0 is the cardinality of the number of sub-division surfaces; Q norr (t) is the amount of waste liquid effectively treated up to time t; Δt is a time interval defined by the system user for determining the incineration efficiency of the incinerator; Q all (t) is the total amount of waste liquid put in until time t; σ(t) is the average standard deviation of the incinerator furnace surface temperature information in the time period [(t-Δt), (t+Δt)] around time t; σ max is the maximum value of the standard deviation; R(t) is the cumulative number of key components replaced by the incinerator up to time t; T is the design service life of the incinerator; W(t) is the time node weight function;

[0030] In the above formula, the left side of the equal sign is rounded up, x0≥9, t is the time from the start of the incinerator to the current operation of the sensor module, Indicates the criticality of the incinerator operation task compared to time node t when the incinerator is running to t;

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

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

[0033] The creation module and the analysis module are customized by the system end user for the number of continuous operations, and the number of continuous operations is not less than two times, and the higher the temperature accuracy requirement of the incinerator furnace, the more continuous operation parameters are set, and vice versa, the fewer the number of continuous operations are set. The system end user in the judgment module customizes and edits a balance judgment threshold. If the mean value of the results of the continuous operation of the analysis module is greater than the balance judgment threshold, it is determined that the temperature inside the incinerator furnace is balanced, and vice versa, it is determined that the temperature inside the incinerator furnace is unbalanced.

[0034] Among them, when the creation module is running continuously, the planes created each time do not overlap.

[0035] Furthermore, the rendering surface symmetry analysis logic of the three-dimensional models of the two sub-incinerator furnaces in the analysis module is:

[0036]

[0037] Where: S is the symmetry of the rendering surfaces of the two sub-incinerator furnace 3D models; W and H are the width and height of the rendering surface of the sub-incinerator furnace 3D model; D(a, b) is the grayscale value difference between the pixel point (a, b) in the rendering surface of the sub-incinerator furnace 3D model and the symmetrical point in the rendering surface of the other sub-incinerator furnace 3D model; I(a, b) is the grayscale value of the pixel point (a, b) after the rendering surface of the sub-incinerator furnace 3D model where the pixel point (a, b) is located is converted into a grayscale image;

[0038] The closer S is to 1, the higher the symmetry of the rendering surfaces of the two sub-incinerator furnace three-dimensional models is, and the closer S is to 0, the lower the symmetry of the rendering surfaces of the two sub-incinerator furnace three-dimensional models is.

[0039] Furthermore, the modeling module is interactively connected to the alarm module through a wireless network, the alarm module is interactively connected to the receiving module and the sensing module through a wireless network, the modeling module is interactively connected to the retrieval module and the rendering module through a wireless network, the rendering module is interactively connected to the creation module through a wireless network, and the creation module is interactively connected to the judgment module through a wireless network.

[0040] In a second aspect, an intelligent monitoring process for a salt-containing and sulfur-containing waste liquid incinerator comprises:

[0041] Temperature sensors are evenly deployed on the surface of the incinerator furnace to sense the surface temperature of the incinerator furnace in real time based on the temperature sensors;

[0042] A three-dimensional model of the incinerator furnace is constructed according to the structural parameters of the incinerator furnace, and 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 rendering color of the incinerator furnace 3D model surface, set the ratio of rendering saturation to distance, subdivide the segmented surface into several sub-segments, and render each sub-segment based on the distance of each sub-segment and the set ratio of rendering saturation to distance, so that the rendering saturation of the sub-segment at the center is 100%;

[0044] Create a plane on the central axis of the rendered 3D model of the incinerator hearth. Cut the 3D model of the incinerator hearth based on the created plane to obtain two sub-3D models of the incinerator hearth. Analyze the symmetry of the surface color distribution of the two sub-3D models of the incinerator hearth.

[0045] Determine whether the temperature inside the incinerator furnace is balanced based on the results of the symmetry analysis.

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

[0047] Beneficial effects:

[0048] The present invention provides an intelligent monitoring system for a salt-containing and sulfur-containing waste liquid incinerator. During operation, the system collects temperature information on the surface of the incinerator furnace by deploying temperature sensors on the surface of the incinerator furnace. Based on the collected temperature information, it determines whether the working state of the incinerator furnace is safe. A three-dimensional model of the incinerator furnace is further constructed, and the surface of the three-dimensional model of the incinerator furnace is rendered in combination with the temperature information. The symmetry of the color distribution on the model surface is analyzed according to the rendering result, so as to make a final judgment on whether the temperature inside the incinerator furnace is balanced. This helps the incinerator operator to grasp the temperature balance state of the incinerator furnace more quickly and in real time, and brings intelligent monitoring of the operation safety of the incinerator.

[0054] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

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

[0056] Example 1:

[0057] The intelligent monitoring system of a salt-containing sulfur-containing waste liquid incinerator of this embodiment is as follows: Figure 1 As shown, it includes: perception layer, modeling layer and analysis layer;

[0058] The temperature information of the incinerator's furnace surface is collected in real time by the perception layer. The temperature information is summarized in the perception layer and sent to the modeling layer in real time. The modeling layer synchronously receives the temperature information fed back by the perception 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 temperature inside the incinerator furnace is balanced based on the furnace temperature model and the waste liquid incineration parameters.

[0059] The perception layer includes a sensor module, a receiving module, and an alarm module. The sensor 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 sensor module and summarize the temperature information. The alarm module is used to set the safety judgment interval of the incinerator furnace working state, and compare the safety judgment interval of the incinerator furnace working state with the temperature information summarized by the receiving module to determine whether the incinerator furnace working state is safe.

[0060] Among them, the sensor module is integrated with a temperature sensor. The sensor module is provided in several groups. The several groups of sensor modules are evenly distributed on the surface of the incinerator furnace. The distance between adjacent sensor modules is equal. The receiving module summarizes the temperature information by: identifying the sensor module that sources the temperature information, obtaining the position coordinates of each sensor module on the surface of the incinerator furnace, marking the position coordinates corresponding to the sensor module that sources the temperature information with the temperature information, and packaging all the temperature information marked with the position coordinates to obtain a temperature information data packet;

[0061] When the sensor modules are deployed on the surface of the incinerator furnace, the following requirements must be met: the distance between adjacent sensor modules should not exceed L / 20, where L is the length of the incinerator furnace;

[0062] The safety judgment interval of the incinerator furnace working status set in the alarm module is customized by the system end user. The alarm module is integrated with the speaker and the control unit. The speaker stores the alarm audio customized by the system end user. The alarm module will generate an alarm when it determines that:

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

[0064] When the alarm module determines that two or more temperature information do not meet the safety judgment range of the incinerator furnace working state, it will simultaneously evaluate the incinerator operation risk. The evaluation logic is expressed 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 interval of the incinerator furnace working state; d(i,i+1) is the distance between the sensor module of the i-th temperature information and the i+1-th temperature information source and the incinerator furnace surface; T i is the temperature value represented by the i-th temperature information; min G is the end value with the smallest difference from the temperature information among the two end values ​​of the incinerator furnace working state safety judgment interval;

[0067] in, Express The larger the incinerator operation risk value f is, the higher the incinerator operation risk is; conversely, the lower the incinerator operation risk is.

[0068] The above formula is used to digitally calculate the operating risk of the incinerator. In the implementation scenario of this system, based on the calculation results, the incinerator operator can be assisted in further suitability safety management of the incinerator in combination with the analysis results of whether the temperature inside the incinerator furnace is balanced. Alternatively, the calculation results of the above formula can be applied to the analysis process of whether the temperature inside the incinerator furnace is balanced, so as to improve the accuracy of the final analysis results of whether the temperature inside the incinerator furnace is balanced.

[0069] The modeling layer includes a modeling module, a retrieval module and a rendering module. The modeling module is used to upload the incinerator furnace structure parameters and build a three-dimensional model of the incinerator furnace based on the incinerator furnace structure parameters. The retrieval module is used to retrieve the incinerator furnace surface temperature information collected in real time in the perception layer. The rendering module is used to receive the incinerator furnace three-dimensional model constructed in the modeling module and the incinerator furnace surface temperature information retrieved in the retrieval module, and render the surface of the incinerator furnace three-dimensional model based on the incinerator furnace surface temperature information.

[0070] 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 sensor modules, and the sizes of the divisions are equal. The position coordinates of any point on each division surface are known.

[0071] Further referencing the position coordinates of the temperature information marker, determine the segmentation surface to which the position coordinates of the temperature information marker belong, bind the segmentation surface to the temperature information one by one, select an arbitrary color as the rendering target color, set the ratio of rendering saturation to distance, and further segment the segmentation surface. The segmentation result is recorded as a sub-segmentation surface matrix. The central sub-segmentation surface of the matrix is ​​applied with the rendering target color saturation of 100%, and the sub-segmentation surfaces adjacent to the central sub-segmentation surface of the matrix are rendered based on the ratio of rendering saturation to distance;

[0072] The split surface is obeyed when performing the split operation, and the size and shape of each sub-split surface are equal;

[0073] When performing a split operation on a split surface, the number of sub-split surfaces obtained by splitting follows:

[0074]

[0075] Where: x is the number of sub-division surfaces obtained by segmentation; x0 is the cardinality of the number of sub-division surfaces; Q norr(t) is the amount of waste liquid effectively treated up to time t; Δt is a time interval defined by the system user for determining the incineration efficiency of the incinerator; Q all (t) is the total amount of waste liquid put in until time t; σ(t) is the average standard deviation of the incinerator furnace surface temperature information in the time period [(t-Δt), (t+Δt)] around time t; σ max is the maximum value of the standard deviation; R(t) is the cumulative number of key components replaced by the incinerator up to time t; T is the design service life of the incinerator; W(t) is the time node weight function;

[0076] In the above formula, the left side of the equal sign is rounded up, x0≥9, t is the time from the start of the incinerator to the current operation of the sensor module, Indicates the criticality of the incinerator operation task compared to time node t when the incinerator is running to t;

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

[0078] The above logic formula supports 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 three-dimensional model of the incinerator furnace, and cut the three-dimensional model of the incinerator furnace based on the created plane to obtain two sub-incinerator furnace three-dimensional models. The analysis module is used to receive the two sub-incinerator furnace three-dimensional models obtained by running the creation module, and analyze the rendering surface symmetry of the two sub-incinerator furnace three-dimensional models. The judgment module is used to obtain the rendering surface symmetry analysis results of the two sub-incinerator furnace three-dimensional models in the analysis module, and determine whether the temperature inside the incinerator furnace is balanced based on the analysis results;

[0080] The creation module and the analysis module are customized by the system end user for the number of continuous runs, and the number of continuous runs is not less than both sides, and the higher the temperature accuracy requirement of the incinerator furnace, the more continuous running parameters are set, and vice versa, the fewer the number of continuous runs are set. In the judgment module, the system end user customizes and edits a balance judgment threshold. If the mean value of the results of the continuous operation of the analysis module is greater than the balance judgment threshold, it is determined that the temperature inside the incinerator furnace is balanced, otherwise, it is determined that the temperature inside the incinerator furnace is unbalanced.

[0081] Among them, during the continuous operation of the creation module, the planes created each time do not overlap;

[0082] The analysis logic for the symmetry of the rendering surfaces of the three-dimensional models of the two sub-incinerator furnaces in the analysis module is as follows:

[0083]

[0084] Where: S is the symmetry of the rendering surfaces of the two sub-incinerator furnace 3D models; W and H are the width and height of the rendering surface of the sub-incinerator furnace 3D model; D(a, b) is the grayscale value difference between the pixel point (a, b) in the rendering surface of the sub-incinerator furnace 3D model and the symmetrical point in the rendering surface of the other sub-incinerator furnace 3D model; I(a, b) is the grayscale value of the pixel point (a, b) after the rendering surface of the sub-incinerator furnace 3D model where the pixel point (a, b) is located is converted into a grayscale image;

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

[0086] The above logic formula further defines the analysis logic of the rendering surface symmetry of the sub-incinerator furnace 3D model, thereby presenting the digital calculation results to the system users, providing them with a clearer reference.

[0087] The modeling module is interactively connected to the alarm module through a wireless network, the alarm module is interactively connected to the receiving module and the sensor module through a wireless network, the modeling module is interactively connected to the retrieval module and the rendering module through a wireless network, the rendering module is interactively connected to the creation module through a wireless network, and the creation module is interactively connected to the judgment module through a wireless network.

[0088] In this embodiment, the sensing module senses the incinerator furnace surface temperature information in real time, the receiving module further receives the incinerator furnace surface temperature information sensed by the sensing module, summarizes the temperature information, and the alarm module synchronously sets the incinerator furnace working state safety judgment interval, compares the incinerator furnace working state safety judgment interval with the temperature information summarized by the receiving module, and determines whether the incinerator furnace working state is safe. The modeling module then uploads the incinerator furnace structure parameters, and constructs an incinerator furnace three-dimensional model based on the incinerator furnace structure parameters. The calling module is then called to retrieve the incinerator furnace surface temperature information collected in real time in the perception layer, and the rendering module receives the incinerator furnace constructed in the modeling module in real time. The surface temperature information of the incinerator furnace retrieved in the three-dimensional model and the retrieval module is used to render the surface of the three-dimensional model of the incinerator furnace based on the surface temperature information of the incinerator furnace. Finally, a plane is created on the vertical center axis of the rendered three-dimensional model of the incinerator furnace through the creation module. The three-dimensional model of the incinerator furnace is cut based on the created plane to obtain two sub-incinerator furnace three-dimensional models. The analysis module runs the two sub-incinerator furnace three-dimensional models obtained by the creation module, analyzes the symmetry of the rendering surfaces of the two sub-incinerator furnace three-dimensional models, and obtains the rendering surface symmetry analysis results of the two sub-incinerator furnace three-dimensional models in the analysis module through the judgment module. Based on the analysis results, it is determined whether the temperature inside the incinerator furnace is balanced;

[0089] Through the operation of the system in the above embodiment, full coverage temperature monitoring is provided for the furnace of the salt-containing and sulfur-containing waste liquid incinerator, assisting the incinerator operator to more quickly and conveniently monitor the incinerator's real-time temperature and manage its operation safety;

[0090] See also Figure 3 As shown, based on the marks in the figure, the plane created by the creation module in the analysis layer is further displayed, that is, the vertical central axis constrained by the plane when the plane is created. The rendered three-dimensional model of the incinerator furnace is cut based on the created plane to provide support for the symmetry analysis of the rendering surface of the three-dimensional model of the incinerator furnace.

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

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

[0093] The saturations of the adjacent edge sub-division surfaces of each division surface are adjusted to half of the saturations of the two sub-division surfaces.

[0094] Through the above settings, further operation logic and data support are provided for the modeling layer of the system in the above embodiment, ensuring that the modeling layer in the system operates more stably.
