Description

Technical Field

[0001] This invention relates to the field of waste liquid incinerator technology, specifically to a condition assessment system and method for incinerators containing salt and chlorine. Background Technology

[0002] Salt-containing chlorine waste liquid incinerators are key equipment for treating specific waste liquids. They utilize high-temperature combustion technology to fully oxidize and decompose salt-containing chlorine waste liquids. They can effectively treat various complex waste liquids, converting harmful substances into harmless gases and ash. With high efficiency and environmental friendliness, they play a vital role in chemical and environmental protection fields, contributing to the harmless treatment and resource recycling of waste liquids.

[0003] The invention patent application number 201811408254.1 discloses an environmentally friendly and energy-saving emission system for incinerating high-salt and high-chlorine organic waste liquid, including an adiabatic incinerator, a vertical membrane wall-mounted water-tube waste heat boiler, a cyclone separator, a quench tower, a bag filter dust collector and acid removal spray tower, a flue gas reheater, an SCR denitrification device, an induced draft fan, and a chimney. The chlorine-containing organic waste liquid is injected from the top of the incinerator and mixed with auxiliary fuel and air for combustion. By controlling the amount of auxiliary fuel and air, the temperature at the top of the incinerator is maintained at no less than 1200℃. At this temperature, the chlorine-containing organic matter undergoes an oxidation reaction with oxygen, generating CO2, H2O, NOx, HCl, and a small amount of free C12 and other small molecule compounds. The entire adiabatic incinerator is equivalent to a large Venturi, the narrow throat at the top of the incinerator is equivalent to the throat of the Venturi, the upper part of the incinerator is equivalent to the inlet section of the Venturi, and the lower part of the incinerator is equivalent to the Venturi. In the outlet diffusion section, the Venturi effect is utilized to inject NaOH solution or NaOH powder into its throat, which can produce a high adsorption effect, enhancing the reaction between acidic gas containing HCl and NaOH to generate NaCl. The flue gas generated in the upper part of the incinerator enters the lower part of the incinerator through a narrow throat. NaOH solution or NaOH powder nozzles are arranged at the throat position. Due to the increased flue gas velocity at the throat position, the injected NaOH solution or NaOH powder can be mixed evenly with the flue gas, thereby improving the reaction efficiency of NaOH and HCl.

[0004] The application aims to address the problem that "HCl gas and NOx produced by existing incineration technology have not undergone special environmental protection treatment, so it is difficult for the flue gas produced after incineration to meet the emission control requirements of national environmental protection standards."

[0005] However, for existing salt and chlorine-containing waste liquid incinerators, the waste liquid is sprayed out in the form of atomization to improve the incineration efficiency. However, the monitoring of the incineration effect during the incineration process often focuses on the quality assessment of the exhaust gas output after the waste liquid is incinerated to further evaluate the incineration status and effect. This method has poor timeliness and lacks predictability, resulting in high management requirements for the operation of the incinerator.

[0006] To address this, a condition assessment system for incinerators containing salt and chlorine waste liquids is proposed. Summary of the Invention

[0007] To address the aforementioned shortcomings of existing technologies, this invention provides a system and method for assessing the condition of a saline and chlorine-containing wastewater incinerator, thus solving the technical problems mentioned in the background section.

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

[0009] In a first aspect, a condition assessment system for a saline and chlorine-containing waste liquid incinerator includes: a capture layer, a control layer, and an assessment layer;

[0010] During the treatment of saline and chlorine-containing wastewater, the internal state parameters of the wastewater during the atomization and combustion stages are captured by the capture layer. The control layer simultaneously receives the internal state parameters of the incinerator captured by the capture layer and decides whether to stop the current incineration task based on the internal state parameters. If the decision control result is negative, the internal state parameters of the incinerator are stored. The evaluation layer is triggered simultaneously to obtain the internal state parameters of the incinerator from the control layer and evaluate the health status tendency of the incinerator based on the internal state parameters.

[0011] The control layer includes an analysis module, a decision module, and a storage module. The analysis module is used to receive the internal state parameters of the incinerator captured by the capture layer and analyze the health of the internal state of the incinerator based on the internal state parameters. The decision module is used to receive the health analysis results of the internal state of the incinerator from the analysis module and control whether the current incineration task process of the incinerator is stopped based on the decision results. The storage module is used to obtain the internal state parameters of the incinerator received by the analysis module and store the internal state parameters of the incinerator.

[0012] The analysis logic for assessing the health status of the incinerator's internal condition within the analysis module is expressed as follows:

[0013] Segment the optical path region image from the latest acquired optical path image, and calculate the center coordinates of the optical path region image: Where: m is the total number of pixels in the optical path region image; (x j x j Let be the coordinates of the j-th pixel;

[0014] Based on (x) center ,y center The optical path region image is divided into four quadrants, denoted as A1, A2, A3, and A4.

[0015]

[0016] In the formula: H1 represents the health status of the incinerator's internal condition as shown in the optical path image; ΔA 1-3 ΔA represents the relative area difference between the optical path regions located in quadrants A1 and A3; 2-4 I represents the relative area difference between the optical path regions located in quadrants A2 and A4; A is the area of ​​the optical path region image; I j Let I be the brightness of the i-th pixel; avg I represents the average brightness of the image in the optical path region. max H1 represents the maximum brightness of the image in the optical path region; H2 represents the internal health of the incinerator as perceived by the sensing module.

[0017] The decision module has two sets of health judgment thresholds for the internal state of the incinerator. Based on the comparison of the two sets of judgment thresholds with H1 and H2 respectively, the internal state of the incinerator is judged to be healthy when both H1 and H2 meet their respective health judgment thresholds. Otherwise, the internal state of the incinerator is judged to be unhealthy, and the decision module controls the current incineration task process of the incinerator to stop.

[0018] Furthermore, the capture layer includes an optical path module, a sensing module, and a control module. The optical path module is used to capture the optical path image formed by the light source when the salt and chlorine-containing waste liquid is atomized and sprayed out. The sensing module is used to sense the combustion state parameters of the salt and chlorine-containing waste liquid in the incinerator. The control module is used to set the operating cycle and is applied to the optical path module and the sensing module to enable the optical path module and the sensing module to operate synchronously and continuously based on the operating cycle.

[0019] The sensing module integrates a gas composition sensor, a temperature sensor, and a water composition sensor. Several groups of temperature sensors are arranged in a ring at equal intervals on the top wall of the incinerator. The water composition sensor is located inside the atomizing nozzle of the salt and chlorine-containing waste liquid on the incinerator. The gas composition sensor is located at the exhaust gas output end of the incinerator. The control module has a set operating cycle setting logic, and the control module executes the set operating cycle based on the operating cycle setting logic.

[0020] Furthermore, the optical path module is integrated with an industrial camera and lighting equipment. Both the industrial camera and lighting equipment are deployed inside the incinerator. The shooting end direction and the light source direction of the industrial camera and lighting equipment are perpendicular to the jet wind direction of the atomized spray head of the salt and chlorine-containing waste liquid in the incinerator from a top-down perspective. The brightness of the lighting equipment is higher than the brightness of the flame inside the incinerator.

[0021] When the atomizing nozzles spray out mist of salt and chlorine-containing waste liquid inside the incinerator, the lighting equipment continues to operate, and the industrial camera and control module continuously collect optical path images during the set operating cycle.

[0022] During the stage where the salt and chlorine-containing waste liquid is sprayed out of the atomizing nozzle in the incinerator, the lighting equipment and its side illuminate the atomized salt and chlorine-containing waste liquid to form the Tyndall effect. The image data collected by the industrial camera under the Tyndall effect is recorded as the optical path image.

[0023] Furthermore, the logic for setting the operating cycle in the control module is as follows:

[0024] The system user defines the initial running cycle in the control module, denoted as d0;

[0025]

[0026] In the formula; k is the operating cycle adjustment ratio; n is the total number of cycles required for the incinerator to treat saline and chlorine-containing wastewater; n′ is the number of cycles that have been completed; d i ω1 is the time of the i-th cycle; gi is the mass of the salt- and chlorine-containing wastewater atomized by the nozzle in the incinerator during the i-th cycle; ω1 and ω2 are weights; η is the control factor.

[0027] The total number of cycles n required for the incinerator to treat saline and chlorine-containing wastewater and the control factor η are user-defined on the system side. The control factor η > 0, the weights ω1 and ω2 are both positive numbers, the sum of the weights ω1 and ω2 equals 1, and ω1 > ω2. The control factor η controls the operating cycle adjustment ratio k to always be within the range of (0, 1). This represents the total mass of the saline and chlorine-containing waste liquid stored in the incinerator to be atomized and sprayed. Based on the above formula, the new operating cycle is calculated. When the initial operating cycle is d0, the next operating cycle is d0×k, and the next operating cycle after d0×k is d0×k. 2 And so on, all the execution cycles that are applied in sequence are denoted as d0, And d0, obey

[0028]

[0029] Furthermore, the analysis module receives the internal state parameters of the incinerator, namely the optical path images, temperature values, proportions of each component in the saline and chlorine-containing wastewater, and proportions of each component in the incinerator's output exhaust gas, which are collected and sensed by the optical path module and sensing module in the capture layer during historical operation.

[0030] When the decision module controls the current incineration task process of the incinerator to stop, the spray nozzle of the mist-containing salt and chlorine waste liquid on the incinerator is immediately closed, and the incineration station of the incinerator is closed synchronously with a delay. The time used for the delayed closure of the incinerator is customized by the system user.

[0031] When the storage module stores the internal state parameters of the incinerator, it simultaneously stores the health analysis results of the internal state of the incinerator in the analysis module. The internal state parameters of the incinerator stored in the storage module are distinguished and stored based on their corresponding health analysis results of the internal state of the incinerator.

[0032] Furthermore, the internal health status H2 of the incinerator, as perceived by the sensing module, is calculated using the following formula:

[0033]

[0034] In the formula: u represents the total number of temperature sensors; C v The temperature value sensed by the v-th temperature sensor during the latest run of the sensing module; C0 is the rated temperature inside the incinerator; q is the total number of runs of the sensing module; f(W) p f(W) represents the percentage of target substances for incineration in the saline and chlorine-containing wastewater sensed during the p-th run of the sensing module; f(Q) represents the rated percentage of target substances for incineration in the saline and chlorine-containing wastewater before incineration; f(Q) represents the percentage of target substances for incineration in the saline and chlorine-containing wastewater before incineration. p f(Q)0 represents the percentage of harmful components in the output exhaust gas detected during the p-th run of the sensing module; f(Q)0 represents the target percentage of harmful substances in the output exhaust gas.

[0035] Among them, C0, f(W)0, and f(Q)0 are defined by the system user. The larger H1 is, the healthier the internal state of the incinerator. The smaller H2 is, the healthier the internal state of the incinerator.

[0036] Furthermore, the evaluation layer includes an evaluation module, an identification module, and an output module. The evaluation module is used to receive the internal state parameters of the incinerator stored in the storage module and evaluate the health status tendency of the incinerator based on the internal state parameters of the incinerator. The identification module is used to identify the source of the decline when the health status tendency of the incinerator is declining. The output module is used to obtain the identification result of the source of the decline obtained by the identification module and output the identification result.

[0037] During the evaluation module's operation phase, based on the analysis logic of the analysis module in the control layer, the internal state parameters of the incinerator stored in the storage module are continuously calculated: the health status of the incinerator's internal state as represented by the optical path image, and the health status of the incinerator's internal state as represented by the internal state parameters perceived by the sensing module, denoted as (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... Simultaneously, two sets of situation diagrams are created based on (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... , respectively. The horizontal axis of the situation diagram represents time, and the vertical axis represents (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... The output module connects to the mobile computer device held by the system user via a wireless network (H1)2, (H1)3, ... or (H2)1, (H2)2, (H3)3, ...) to transmit the weakening situation source identification results to the mobile computer device. The weakening situation source identification results include: misty saline and chlorine-containing waste liquid and incinerator. The weakening situation source identification results correspond to the situation diagrams created for misty saline and chlorine-containing waste liquid and (H1)1, (H1)2, (H1)3, ..., and the weakening situation source identification results correspond to the situation diagrams created for incinerator and (H2)1, (H2)2, (H3)3, ..., respectively. The situation diagrams are in the form of line graphs.

[0038] Furthermore, during the operation phase of the assessment module, the two sets of situation maps are traversed to identify whether there are continuously decreasing line segments in the situation maps corresponding to (H1)1, (H1)2, (H1)3, ... and whether there are continuously increasing line segments in the situation maps corresponding to (H2)1, (H2)2, (H3)3, ... When either situation is identified, the incinerator's health status is assessed as declining. The identification module runs synchronously to obtain the situation map from which the assessment results are obtained in the assessment module, and the source of health represented by the situation map is taken as the source of the declining status.

[0039] Furthermore, the analysis module is interconnected with a control module via a wireless network, the control module is interconnected with a sensing module and an optical path module via a wireless network, the analysis module is interconnected with a decision module and a storage module via a wireless network, the storage module is interconnected with an evaluation module via a wireless network, and the evaluation module is interconnected with an identification module and an output module via a wireless network.

[0040] Secondly, a method for assessing the condition of a saline- and chlorine-containing waste incinerator includes the following steps:

[0041] Set a capture cycle, and capture the state parameters of the salt and chlorine-containing waste liquid in the incinerator during the atomization and combustion stages based on the capture cycle;

[0042] The health status of the incinerator's internal condition is analyzed based on the optical path images captured from the incinerator's internal state parameters.

[0043] The health status of the incinerator's internal condition is analyzed based on the captured parameters, including temperature, the proportion of each component in the saline and chlorine-containing wastewater, and the proportion of each component in the incinerator's output exhaust gas.

[0044] The results of two sets of internal health analysis of the incinerator were used to determine whether the incinerator was currently healthy. If the result was unhealthy, the incinerator was controlled to stop the current incineration process. If the result was healthy, the health trend of the incinerator was further evaluated.

[0045] When the incinerator health status tends to be weak, identify the source of the weakness; when the incinerator health status tends to be non-weak, reset the system operation.

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

[0047] Beneficial effects:

[0048] This invention provides a status assessment system for a saline-chlorine wastewater incinerator. During operation, the system captures internal status parameters of the incinerator during the atomization and combustion stages of the saline-chlorine wastewater, simultaneously determining the incinerator's real-time health status. If the incinerator becomes unhealthy, the system controls the incinerator to terminate the incineration process in real time, preventing further operational failures. Furthermore, when the incinerator is in a healthy state, the system can further assess its health trend, thus providing a degree of predictive visual monitoring and assessment of the incinerator's status. This effectively brings comprehensive and distributed management benefits to the incinerator, ensuring safe and stable operation, improving the incinerator's intelligent operation, and ensuring stable incineration of saline-chlorine wastewater. Simultaneously, a saline-chlorine wastewater incinerator status assessment method provides further operational logic support for the system, ensuring stable operation. Attached Figure Description

[0055] 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.

[0056] The present invention will be further described below with reference to embodiments.

[0057] Example 1:

[0058] This embodiment provides a condition assessment system for a saline and chlorine-containing waste liquid incinerator, such as... Figure 1 As shown, it includes: a capture layer, a control layer, and an evaluation layer;

[0059] During the treatment of saline and chlorine-containing wastewater, the internal state parameters of the wastewater during the atomization and combustion stages are captured by the capture layer. The control layer simultaneously receives the internal state parameters of the incinerator captured by the capture layer and decides whether to stop the current incineration task based on the internal state parameters. If the decision control result is negative, the internal state parameters of the incinerator are stored. The evaluation layer is triggered simultaneously to obtain the internal state parameters of the incinerator from the control layer and evaluate the health status tendency of the incinerator based on the internal state parameters.

[0060] The capture layer includes an optical path module, a sensing module, and a control module. The optical path module is used to capture the optical path image formed by the light source when the salt and chlorine-containing waste liquid is atomized and sprayed out. The sensing module is used to sense the combustion state parameters of the salt and chlorine-containing waste liquid in the incinerator. The control module is used to set the operating cycle and is applied to the optical path module and the sensing module to enable the optical path module and the sensing module to operate synchronously and continuously based on the operating cycle.

[0061] The sensing module integrates a gas composition sensor, a temperature sensor, and a water composition sensor. Several groups of temperature sensors are arranged in a ring at equal intervals on the top wall of the incinerator. The water composition sensor is located inside the atomizing nozzle of the salt and chlorine waste liquid in the incinerator. The gas composition sensor is located at the exhaust gas output end of the incinerator. The control module is equipped with an operating cycle setting logic, and the control module executes the operating cycle setting based on the operating cycle setting logic.

[0062] The logic for setting the operating cycle in the control module is as follows:

[0063] The system user defines the initial running cycle in the control module, denoted as d0;

[0064]

[0065] In the formula; k is the operating cycle adjustment ratio; n is the total number of cycles required for the incinerator to treat saline and chlorine-containing wastewater; n′ is the number of cycles that have been completed; d i ω1 is the time of the i-th cycle; gi is the mass of the salt- and chlorine-containing wastewater atomized by the nozzle in the incinerator during the i-th cycle; ω1 and ω2 are weights; η is the control factor.

[0066] The total number of cycles n required for the incinerator to treat saline and chlorine-containing wastewater and the control factor η are user-defined on the system side. The control factor η > 0, the weights ω1 and ω2 are both positive numbers, the sum of the weights ω1 and ω2 equals 1, and ω1 > ω2. The control factor η controls the operating cycle adjustment ratio k to always be within the range of (0, 1). This represents the total mass of the saline and chlorine-containing waste liquid stored in the incinerator to be atomized and sprayed. Based on the above formula, the new operating cycle is calculated. When the initial operating cycle is d0, the next operating cycle is d0×k, and the next operating cycle after d0×k is d0×k. 2 And so on, all the execution cycles that are applied in sequence are denoted as d0, And d0, obey

[0067]

[0068] The control layer includes an analysis module, a decision module, and a storage module. The analysis module receives the internal state parameters of the incinerator captured by the capture layer and analyzes the health of the incinerator's internal state based on these parameters. The decision module receives the health analysis results of the incinerator's internal state from the analysis module and controls whether the current incineration task process of the incinerator is stopped based on the decision results. The storage module obtains the internal state parameters of the incinerator received by the analysis module and stores these parameters.

[0069] The analysis logic for the health status of the incinerator's internal condition in the analysis module is represented as follows:

[0070] Segment the optical path region image from the latest acquired optical path image, and calculate the center coordinates of the optical path region image: Where: m is the total number of pixels in the optical path region image; (x j x j Let be the coordinates of the j-th pixel;

[0071] Based on (x) center ,y center The optical path region image is divided into four quadrants, denoted as A1, A2, A3, and A4.

[0072]

[0073] In the formula: H1 represents the health status of the incinerator's internal condition as shown in the optical path image; ΔA 1-3 ΔA represents the relative area difference between the optical path regions located in quadrants A1 and A3; 2-4 I represents the relative area difference between the optical path regions located in quadrants A2 and A4; A is the area of ​​the optical path region image; I j Let I be the brightness of the i-th pixel; avg I represents the average brightness of the image in the optical path region. max H1 represents the maximum brightness of the image in the optical path region; H2 represents the internal health of the incinerator as perceived by the sensing module.

[0074] The decision module is equipped with two sets of health determination thresholds for the internal state of the incinerator. Based on the comparison of the two sets of determination thresholds with H1 and H2 respectively, the internal state of the incinerator is determined to be healthy when both H1 and H2 meet their respective health determination thresholds. Otherwise, the internal state of the incinerator is determined to be unhealthy, and the decision module controls the current incineration task process of the incinerator to stop.

[0075] The internal health status H2 of the incinerator, as perceived by the sensing module, is calculated using the following formula:

[0076]

[0077] In the formula: u represents the total number of temperature sensors; C v The temperature value sensed by the v-th temperature sensor during the latest run of the sensing module; C0 is the rated temperature inside the incinerator; q is the total number of runs of the sensing module; f(W) p f(W) represents the percentage of target substances for incineration in the saline and chlorine-containing wastewater sensed during the p-th run of the sensing module; f(Q) represents the rated percentage of target substances for incineration in the saline and chlorine-containing wastewater before incineration; f(Q) represents the percentage of target substances for incineration in the saline and chlorine-containing wastewater before incineration. pf(Q)0 represents the percentage of harmful components in the output exhaust gas detected during the p-th run of the sensing module; f(Q)0 represents the target percentage of harmful substances in the output exhaust gas.

[0078] Among them, C0, f(W)0, and f(Q)0 are defined by the system user. The larger H1 is, the healthier the internal state of the incinerator is, and the smaller H2 is, the healthier the internal state of the incinerator is.

[0079] The evaluation layer includes an evaluation module, an identification module, and an output module. The evaluation module is used to receive the internal state parameters of the incinerator stored in the storage module and evaluate the health status tendency of the incinerator based on the internal state parameters of the incinerator. The identification module is used to identify the source of the decline when the health status tendency of the incinerator is declining. The output module is used to obtain the identification results of the source of the decline obtained by the identification module and output the identification results.

[0080] During the evaluation module's operation phase, based on the analysis logic of the analysis module in the control layer, the internal state parameters of the incinerator stored in the storage module are continuously calculated: the health status of the incinerator's internal state as represented by the optical path image, and the health status of the incinerator's internal state as represented by the internal state parameters perceived by the sensing module, denoted as (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... Simultaneously, two sets of situation diagrams are created based on (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... respectively. The horizontal axis of the situation diagram represents time, and the vertical axis represents (H1)1, (H1)2, (H1)3, ... and (H2)1, (H2)2, (H3)3, ... The output module connects to the mobile computer device held by the system user via a wireless network and transmits the weakening situation source identification results to the mobile computer device. The weakening situation source identification results include: misty saline and chlorine-containing waste liquid and incinerator. The situation diagrams created for misty saline and chlorine-containing waste liquid and (H1)1, (H1)2, (H1)3, ... in the weakening situation source identification results correspond to the situation diagrams created for (H1)1, (H1)2, (H1)3, ... in the weakening situation source identification results. The situation diagrams created for incinerator and (H2)1, (H2)2, (H3)3, ... are in the form of line graphs.

[0081] During the evaluation module's operation phase, it iterates through the two sets of situation maps, identifying whether there are continuously decreasing line segments in the situation maps corresponding to (H1)1, (H1)2, (H1)3, ... and whether there are continuously increasing line segments in the situation maps corresponding to (H2)1, (H2)2, (H3)3, ... When either situation is identified, the incinerator's health status is assessed as declining. The identification module runs synchronously, acquiring the situation map representing the evaluation results from the evaluation module, and using the health status source represented by the situation map as the source of the declining status.

[0082] The analysis module is interconnected with the control module via a wireless network. The control module is interconnected with the sensing module and the optical path module via a wireless network. The analysis module is interconnected with the decision-making module and the storage module via a wireless network. The storage module is interconnected with the evaluation module via a wireless network. The evaluation module is interconnected with the identification module and the output module via a wireless network.

[0083] In this embodiment, the optical path module captures the optical path image formed by the light source when the saline and chlorine-containing waste liquid is atomized and sprayed out. The sensing module then senses the combustion state parameters of the saline and chlorine-containing waste liquid inside the incinerator. The control module further sets the operating cycle and applies it to the optical path module and the sensing module, so that the optical path module and the sensing module operate synchronously and continuously based on the operating cycle. The analysis module further receives the internal state parameters of the incinerator captured by the capture layer and analyzes the health of the incinerator based on the internal state parameters. The decision module receives the health analysis results of the incinerator internal state from the analysis module in real time and controls whether to stop the current incineration task process based on the decision results. The storage module synchronously obtains the internal state parameters of the incinerator received by the analysis module and stores the internal state parameters of the incinerator. Then, the evaluation module receives the internal state parameters of the incinerator stored in the storage module and evaluates the health trend of the incinerator based on the internal state parameters. When the health trend of the incinerator is weakening, the identification module identifies the source of the weakening trend. Finally, the output module obtains the identification result of the source of the weakening trend obtained by the identification module and outputs the identification result.

[0084] Through the system operation in the above embodiments, an operational status assessment is provided for the operation of the salt and chlorine incinerator, effectively managing the incinerator and ensuring greater stability of the incinerator during the spraying and incineration of the misty salt and chlorine waste liquid, thereby effectively treating the salt and chlorine waste liquid through incineration.

[0085] See Figure 2 As shown in the figure, incineration station 1 of the incinerator is further illustrated by the labels. Using incineration station 1 as a reference, it is further marked with arrows (incineration station 1 is viewed from above):

[0086] The upward arrow in the diagram indicates the direction of the spray of mist-like saline and chlorine-containing waste liquid;

[0087] The right arrow in the diagram indicates the optical path image acquisition direction of the industrial camera;

[0088] The left arrow in the diagram indicates the direction of the light source emitting from the lighting device;

[0089] See Figure 4 As shown, the figure further illustrates an example of a situation diagram representing H1 and H2.

[0091] At the implementation level, based on Example 1, this example refers to... Figure 1 The following is a further detailed description of the condition assessment system for a saline and chlorine-containing waste liquid incinerator in Example 1:

[0092] The optical path module is integrated with an industrial camera and lighting equipment. Both the industrial camera and lighting equipment are deployed inside the incinerator. The shooting end and light source end of the industrial camera and lighting equipment are perpendicular to the jet wind direction of the atomized spray head of the salt and chlorine waste liquid in the incinerator from a top-down perspective. The brightness of the lighting equipment is higher than the brightness of the flame inside the incinerator.

[0093] When the atomizing nozzles spray out mist of salt and chlorine-containing waste liquid inside the incinerator, the lighting equipment continues to operate, and the industrial camera and control module continuously collect optical path images during the set operating cycle.

[0094] During the stage where the salt and chlorine-containing waste liquid is sprayed out of the atomizing nozzle in the incinerator, the lighting equipment and its side illuminate the atomized salt and chlorine-containing waste liquid to form the Tyndall effect. The image data collected by the industrial camera under the Tyndall effect is recorded as the optical path image.

[0095] The above settings further limit the structure of the optical path module, the source of the optical path image, and the acquisition logic, ensuring stable acquisition of the optical path image and providing necessary operational data support for the subsequent operation of the system in Example 1.

[0096] like Figure 1 As shown, the analysis module receives the internal state parameters of the incinerator, namely the optical path images, temperature values, proportions of each component in the saline and chlorine-containing wastewater, and proportions of each component in the incinerator output exhaust gas from the historical operation of the optical path module and sensing module in the capture layer.

[0097] When the decision module stops the current incineration task process of the incinerator, the spray nozzle of the mist-containing salt and chlorine waste liquid on the incinerator is immediately closed, and the incineration station of the incinerator is closed synchronously with a delay. The time used for the delayed closure of the incinerator is defined by the system user.

[0098] When the storage module stores the internal state parameters of the incinerator, it simultaneously stores the health analysis results of the internal state of the incinerator in the analysis module. Furthermore, the internal state parameters of the incinerator stored in the storage module are distinguished and stored based on their corresponding health analysis results of the internal state of the incinerator.

[0099] The above settings further limit the content of the internal state parameters of the incinerator and limit the logic of the decision module to stop the current incineration task process, ensuring that the decision module in the system can reliably and intelligently control the incinerator in an unhealthy state.

[0100] Example 3:

[0101] At the implementation level, based on Example 1, this example refers to... Figure 2 The following is a further detailed description of the condition assessment system for a saline and chlorine-containing waste liquid incinerator in Example 1:

[0102] A method for assessing the condition of an incinerator containing saline and chlorine waste liquid includes the following steps:

[0103] Set a capture cycle, and capture the state parameters of the salt and chlorine-containing waste liquid in the incinerator during the atomization and combustion stages based on the capture cycle;

[0104] The health status of the incinerator's internal condition is analyzed based on the optical path images captured from the incinerator's internal state parameters.

[0105] The health status of the incinerator's internal condition is analyzed based on the captured parameters, including temperature, the proportion of each component in the saline and chlorine-containing wastewater, and the proportion of each component in the incinerator's output exhaust gas.

[0106] The results of two sets of internal health analysis of the incinerator were used to determine whether the incinerator was currently healthy. If the result was unhealthy, the incinerator was controlled to stop the current incineration process. If the result was healthy, the health trend of the incinerator was further evaluated.

[0107] When the incinerator health status tends to be weak, identify the source of the weakness; when the incinerator health status tends to be non-weak, reset the system operation.

[0108] In summary, during operation, the system in the above embodiments captures internal state parameters of the incinerator during the atomization and combustion stages of the saline and chlorine-containing waste liquid, simultaneously determining the real-time health status of the incinerator. If the incinerator becomes unhealthy, the system controls the incinerator to terminate the incineration process in real time, ensuring that the incinerator does not continue operating and cause more serious operational failures. Furthermore, when the incinerator is in a healthy state, the system can further assess the incinerator's health trend, thereby providing a certain degree of predictive visual monitoring and assessment of the incinerator's status. This effectively brings comprehensive and distributed management effects to the incinerator, ensuring safe and stable operation, improving the incinerator's operational intelligence, and stably treating saline and chlorine-containing waste liquid. Simultaneously, the methods in the above embodiments provide further operational logic support for the system, ensuring stable system operation.

[0109] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
