Description

Technical Field

[0001] This invention relates to the field of industrial pollution reduction and carbon reduction technology, specifically a collaborative treatment system for reducing pollution and carbon emissions from organic waste gas in industrial parks. Background Technology

[0002] With the continuous advancement of large-scale construction and industrial operations in industrial parks, organic waste gases (such as VOCs) and medium-to-high temperature waste heat generated during construction have become key factors affecting the environmental quality and low-carbon development of industrial parks. Uncontrolled emissions of organic waste gases can cause air pollution, damage the regional ecological environment, and threaten the safety of production and living environments. Direct emissions of medium-to-high temperature waste heat can cause significant energy losses and exacerbate energy waste. Currently, the treatment of organic waste gases, utilization of waste heat, and carbon control within the industry are independent and have not formed a coordinated governance system. Against the backdrop of increasingly stringent environmental regulations and the promotion of dual-carbon goals, industrial parks urgently need to integrate pollution control, energy recycling, and carbon emission reduction functions, build integrated collaborative treatment technologies, address the industry pain point of the disconnect between pollution control, energy utilization, and carbon control, and promote the green, low-carbon, and highly efficient transformation of industrial parks.

[0003] Traditional industrial park organic waste gas and waste heat treatment models have many shortcomings. Waste gas and waste heat are mostly collected and treated separately, and waste heat resources are not effectively recovered and utilized. Organic waste gas treatment relies on external heat sources, which significantly increases the system's energy consumption. Waste gas collection methods lack specificity and cannot adapt to the emission characteristics of different work positions, making it easy for pollutants to escape unorganized. The airflow pretreatment process is imperfect, and impurities and fluctuations in operating conditions can continuously interfere with the subsequent treatment effect. The heat storage stage lacks precise control methods, resulting in low heat utilization efficiency. Flue gas treatment does not match the operating conditions of the carbon capture process, making it difficult to guarantee the carbon capture effect. The carbon resource utilization path is singular and cannot form a closed loop. The system is not equipped with full-process dynamic control and safety interlocking mechanisms, resulting in insufficient operational stability and safety. Pollution reduction and carbon reduction cannot work together, making it difficult to meet the industrial park's needs for efficient, stable, and low-carbon governance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a collaborative treatment system for reducing pollution and carbon emissions of organic waste gas (VOCs, etc.) in industrial parks. This system uses medium- and high-temperature waste heat generated during construction as the sole heat source. It achieves waste gas oxidation and decomposition and heat recovery in stages through a three-stage gradient composite heat storage body. It couples gradient heat storage collaborative algorithm and carbon capture collaborative linkage algorithm to precisely control the operating parameters of each module, complete flue gas cooling and purification, CO2 adsorption and purification, and finally achieve carbon resource utilization closed loop through ecological disposal and industrial reuse. It realizes deep synergy of waste heat recovery, waste gas treatment and carbon capture.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a collaborative treatment system for reducing pollution and carbon emissions from organic waste gas in industrial parks, the system comprising:

[0006] Collaborative collection module: Simultaneous and closed collection of medium and high temperature waste heat (200℃-600℃) and organic waste gas generated during the construction process of the industrial park; sequential dust removal, demisting and flow stabilization treatment of the mixed airflow; and establishing stable supply conditions for the gas and heat sources at the front end of the system.

[0007] Gradient heat storage module: It is equipped with a three-stage gradient composite heat storage body. Construction waste heat is used as the only reaction heat source of the system. The construction waste heat is the medium and high temperature waste heat generated during the construction process of the collaborative collection module. The comprehensive collaborative heat storage efficiency is calculated by the gradient heat storage collaborative algorithm, and the heat storage and release rhythm of the heat storage body is adjusted according to the calculation results. The heat storage body forms an organic waste gas oxidation reaction space of 800℃-850℃, which completes the oxidative decomposition of organic waste gas and the cascade recovery of the heat of flue gas generated after oxidation decomposition.

[0008] Flue gas conditioning module: Adapts to the flue gas output from the gradient heat storage module, performs cooling, purification, dehumidification and flow stabilization and homogenization treatment on the flue gas, regulates the temperature, humidity and concentration parameters of the airflow, and shapes the operating conditions that meet the requirements of the carbon capture process.

[0009] Carbon capture module: It performs adsorption and purification operations for carbon dioxide concentrations of 15%-25% in flue gas, and uses a carbon capture collaborative linkage algorithm to calculate the net carbon dioxide capture efficiency. It completes the transportation and utilization of carbon dioxide through two paths: ecological disposal and industrial reuse, and builds a closed-loop operation structure for carbon resource utilization.

[0010] Dynamic control module: Collects various operating parameters of the entire system, coordinates the working condition adaptation and parameter coordination among various modules through gradient heat storage synergy algorithm and carbon capture synergy linkage algorithm, completes closed-loop control of the entire system, and independently executes safety interlocking operations to maintain the stable operation of the system under all working conditions.

[0011] Furthermore, in the collaborative collection module, the closed collection specifically involves: tailoring the emission characteristics of different workstations during construction in the industrial park, employing differentiated closed collection methods to simultaneously collect medium- and high-temperature waste heat and organic waste gas. For mobile workstations, a closed gas collection structure that can be adjusted synchronously with the work equipment is used, forming a local closed space adjacent to the work area to contain and collect all waste heat and organic waste gas generated during the operation, preventing unorganized dispersion. For fixed workstations, an integrated closed space structure is used to completely enclose the work area. Internal airflow guides the waste heat and organic waste gas to prevent outward diffusion, ensuring all is collected. The collected waste heat and organic waste gas converge through a closed channel, maintaining the channel's airtightness throughout the convergence process to prevent leakage along the way, ensuring all waste heat and organic waste gas enter the subsequent treatment stages, and establishing stable supply conditions for the system's front-end gas and heat sources.

[0012] Furthermore, in the collaborative collection module, the dust removal process targets solid particles generated during construction carried in the mixed airflow. It employs a multi-stage filtration method, first initially filtering the airflow to intercept larger solid impurities, then using a fine filtration stage to remove fine dust particles, ensuring no solid impurities remain in the airflow. The demisting process targets liquid water mist and oil mist carried in the mixed airflow. Through gas-liquid separation, the airflow flows within a specific structure, utilizing inertia to separate the liquid impurities from the airflow. The separated liquid impurities are collected and processed, preventing liquid substances from entering subsequent modules with the airflow. The flow stabilization process introduces the mixed airflow after dust removal and demisting into a dedicated buffer structure. Through buffering and uniform distribution of the airflow, it smooths out fluctuations in airflow flow and temperature, maintaining a uniform and stable flow state, ensuring consistent output airflow conditions, and guaranteeing a stable supply of air and heat to the system's front-end.

[0013] Furthermore, in the gradient heat storage module, three-section gradient composite heat storage bodies are arranged sequentially along the flue gas flow direction. Each section is seamlessly connected by a sealed structure, forming a complete tiered heat storage system. These sections correspond to different temperature ranges and receive construction waste heat from 200℃ to 600℃. The first section is a low-temperature heat storage section, corresponding to the 200℃-350℃ temperature range, receiving the initial low-temperature construction waste heat and completing preliminary heat storage. The second section is a medium-temperature heat storage section, corresponding to the 350℃-500℃ temperature range, receiving the heat pretreated from the low-temperature section. The intermediate-temperature waste heat is further absorbed and transferred; the third stage is the high-temperature heat storage stage, corresponding to the temperature range of 500℃-750℃, which receives the heat transferred from the intermediate-temperature stage and performs efficient storage and heating. The three-stage heat storage body, together with the gradient heat storage synergy algorithm, precisely controls the heat storage and release rhythm of each stage, gradually raising the absorbed construction waste heat of 200℃-600℃ to 800℃-850℃, providing stable heat support for the oxidation reaction space of organic waste gas, and at the same time, after the organic waste gas is oxidized and decomposed, the heat of the cooled flue gas is recovered in stages.

[0014] Furthermore, in the gradient heat storage module, the mathematical expression of the gradient heat storage collaborative algorithm is:

[0015]

[0016] in, , represents the comprehensive synergistic heat storage efficiency of the gradient heat storage body, and is the core output parameter of the gradient heat storage synergistic algorithm; , , These are the weighting coefficients for the low-temperature, medium-temperature, and high-temperature heat storage sections in a three-section gradient composite heat storage system, respectively, satisfying... + + =1, the weighting coefficient is dynamically allocated according to the temperature distribution of construction waste heat; The single-stage heat storage efficiency of the low-temperature heat storage section corresponds to the temperature range of 200℃-350℃ and is related to the material and structure of the heat storage body in the low-temperature heat storage section. The single-stage heat storage efficiency of the medium-temperature heat storage section corresponds to the temperature range of 350℃-500℃ and is related to the material and structure of the heat storage body in the medium-temperature heat storage section. The single-stage heat storage efficiency of the high-temperature heat storage section corresponds to the temperature range of 500℃-750℃ and is related to the material and structure of the heat storage body in the high-temperature heat storage section. This is a correction factor for the grade of construction waste heat, which is dynamically adjusted based on the temperature fluctuations and impurity content of the construction waste heat. It is the load fluctuation coefficient for construction conditions, adapted to the intermittent working conditions and unstable waste heat state during the construction process.

[0017] Furthermore, the cooling process receives the high-temperature flue gas output from the gradient heat storage module and, through a waste heat recovery heat exchange process, stably controls the flue gas temperature within the range of 40℃-45℃, simultaneously recovering the waste heat of the flue gas. The purification process, targeting the cooled flue gas, sequentially performs high-precision dust removal and deep impurity removal. A filtration process intercepts and removes solid particles with a diameter of 1μm or larger from the flue gas, while an adsorption process removes residual trace organic components and acidic impurities. The dehumidification process, targeting the purified flue gas… Through a dual-tower alternating deep drying process, the relative humidity of the flue gas is stably controlled below 10%, and the flue gas dew point temperature is reduced to -20℃ or below. The flow stabilization and homogenization treatment targets the flue gas after cooling, purification, and dehumidification. Through buffering, pressure stabilization, and operating condition calibration processes, fluctuations in flue gas flow rate, pressure, and component concentration are smoothed out, and the flue gas pressure is stably controlled within the range of 0.2MPa-0.3MPa. The carbon dioxide concentration in the flue gas is stably regulated to the range of 15%-25%, creating operating conditions that meet the requirements of the carbon capture process.

[0018] Furthermore, in the carbon capture module, the adsorption purification process first separates nitrogen, oxygen, and trace impurities from the flue gas. These trace impurities include unremoved fine particles, residual organic components, and acidic substances. During adsorption, the selective adsorption characteristics of the adsorption medium for carbon dioxide are utilized to continuously adsorb carbon dioxide from the flue gas until the adsorption medium reaches saturation. This saturation state is when the adsorption medium's adsorption capacity for carbon dioxide reaches 90%-95% of its designed adsorption capacity. At this point, the adsorption medium can no longer effectively adsorb carbon dioxide. After reaching the preset saturation state, the desorption process is initiated. This involves heating and depressurizing combined with nitrogen and oxygen purging to desorb and release the adsorbed carbon dioxide from the adsorption medium, thus regenerating and recycling the adsorption medium. The desorbed and released carbon dioxide, after conditioning, must meet the following standards: carbon dioxide purity ≥ 99.5%, nitrogen and oxygen content ≤ 0.5%, and no trace impurities remaining. This meets the requirements for ecological disposal and industrial reuse, providing qualified carbon dioxide raw materials for dual-path transportation and utilization.

[0019] Furthermore, the mathematical expression for the carbon capture collaborative linkage algorithm in the capture module is as follows:

[0020]

[0021] in, The net efficiency of carbon dioxide capture is the core output parameter of the carbon capture collaborative algorithm. The overall synergistic heat storage efficiency of the gradient heat storage body is calculated by the gradient heat storage synergistic algorithm. The flue gas conditioning adaptation coefficient is determined by the effects of flue gas cooling, drying, and flow stabilization treatments. The dynamic activity coefficient of the pressure swing adsorbent characterizes the active state of the adsorbent during long-term operation. The value represents the actual carbon dioxide concentration at the outlet of the gradient thermal storage module, ranging from 15% to 25%. The carbon dioxide design concentration is used, and the ratio of the two characterizes the effect of oxidative degradation on carbon capture efficiency. The system's overall loss coefficient covers losses throughout the entire process of pipeline transportation, equipment operation, and adsorption / desorption. The carbon capture collaborative linkage algorithm calculates the net carbon dioxide capture efficiency in real time based on the above expression, synchronously controls the adsorption and purification operation parameters, ensures efficient carbon dioxide capture and purification, and is compatible with dual-path transportation and utilization for ecological disposal and industrial reuse.

[0022] Furthermore, in the carbon capture module, both the ecological absorption and industrial reuse pathways are based on adsorbed and purified carbon dioxide. The ecological absorption pathway involves introducing the purified carbon dioxide into the ecological restoration area surrounding the industrial park via a closed-loop transport method. This carbon dioxide is then used for vegetation carbon sequestration enhancement, saline-alkali land improvement, and microalgae cultivation, achieving carbon dioxide fixation and absorption through natural ecological processes. The industrial reuse pathway involves adapting the purified carbon dioxide to industrial production needs and transporting it to high-carbon-consuming production enterprises within the industrial park. This serves as a raw material for chemical synthesis, welding protective gas, and refrigerant, achieving the resource-based recycling of carbon dioxide. The two pathways operate collaboratively, relying on a carbon capture collaborative linkage algorithm to regulate the amount and pace of carbon dioxide transport, ensuring efficient adaptation and orderly connection between the two pathways, ultimately forming a closed-loop carbon resource utilization structure.

[0023] Furthermore, the dynamic control module includes safety interlocks that monitor key parameter thresholds for each module. When the temperature of the gradient heat storage module exceeds 850℃ or falls below 200℃, or when the carbon dioxide purity of the carbon capture module is below 99% or the capture efficiency is below 90%, a first-level interlock is immediately triggered, suspending the operation of the corresponding module and initiating cooling and pressure regulation emergency measures. When the flue gas humidity of the flue gas conditioning module exceeds 10%, the pressure fluctuation exceeds ±0.05MPa, or the system's overall loss coefficient is higher than 0.04, a second-level interlock is triggered, adjusting the collaborative algorithm parameters and issuing an early warning. In case of emergencies such as pipeline leakage, equipment pressure ≥0.4MPa, temperature ≥900℃, or adsorbent activity below 0.94, a third-level interlock is triggered, immediately cutting off the system feed, initiating the shutdown protection procedure, and simultaneously linking the emergency emission device. The interlock status is fed back in real time throughout the process to ensure system safety and controllability and mitigate operational risks.

[0024] Compared with existing technologies, this industrial park organic waste gas pollution reduction and carbon reduction synergistic treatment system has the following beneficial effects:

[0025] I. This invention enables the simultaneous and closed-loop collection of medium- and high-temperature waste heat and organic waste gas generated during construction in industrial parks. It employs a collection structure adaptable to different work positions to prevent the unorganized escape of pollutants. Through dust removal, demisting, and flow stabilization, stable front-end supply conditions are established. Relying on a three-stage gradient composite heat storage body and a proprietary collaborative algorithm, an organic waste gas oxidation reaction space is constructed using construction waste heat as the sole heat source. This achieves efficient decomposition of organic waste gas and tiered recovery of flue gas heat, enabling waste gas degradation treatment without the need for an additional heat source. This effectively reduces system operating energy consumption. Simultaneously, airflow regulation smooths out fluctuations in operating conditions, ensuring a continuous and stable waste gas treatment process. This addresses the problem of disorderly emissions and waste heat waste in industrial parks from the source, simultaneously promoting pollutant treatment and waste heat resource utilization, and improving the overall level of waste gas treatment and energy recycling in industrial parks.

[0026] II. This invention cools, purifies, dehumidifies, and homogenizes the flue gas after oxidation and decomposition, creating stable operating conditions suitable for the carbon capture process. It achieves efficient carbon dioxide separation through adsorption and purification technology, and establishes a closed-loop carbon resource utilization structure by combining ecological disposal and industrial reuse as dual pathways. This allows for diversified resource utilization of the separated carbon dioxide. A dedicated collaborative algorithm controls the capture process in real time, improving the overall efficiency of carbon capture and resource utilization. Simultaneously, a dynamic control module coordinates the adaptation of operating conditions and parameter synergy among various modules, and a multi-level safety interlock mechanism monitors key operating states in real time, promptly addressing abnormal conditions and safety risks to ensure the long-term stable and safe operation of the entire system. This achieves full-process synergy in waste gas treatment, waste heat utilization, and carbon capture resource utilization, helping industrial parks efficiently achieve their pollution reduction and carbon reduction goals.

[0033] Example 1:

[0034] Example of Co-treatment of Organic Waste Gas for Pollution Reduction and Carbon Reduction at Fixed Workstations in Industrial Parks

[0035] This embodiment targets construction scenarios with fixed workstations within industrial parks, deploying a collaborative treatment system for reducing pollution and carbon emissions from organic waste gas. The system operates systematically through its five core modules, such as... Figure 1 As shown, the system fully realizes the collaborative operation of the entire process of organic waste gas treatment, medium and high temperature waste heat utilization, carbon capture and resource utilization, which is in line with the characteristics of fixed work positions with concentrated emissions and relatively stable operating conditions, so that all links of the system can be efficiently connected and operate stably.

[0036] The collaborative collection module employs an integrated, enclosed space structure for fixed workstations, completely sealing off the entire work area. Utilizing a customized internal airflow guidance structure, it directs all waste heat (200℃-600℃) and organic waste gas generated during construction towards the collection port, completely blocking the outward diffusion of waste gas and heat, thus preventing fugitive emissions at the source. The collected mixed airflow is then converged through a fully enclosed conveying channel, which remains sealed throughout to prevent leakage during transport. This ensures that all waste heat and waste gas can be completely absorbed into subsequent treatment stages, providing a continuous and sufficient air supply to the system's front end. Heat source; After the mixed airflow converges, it sequentially enters the multi-stage filtration and dust removal, inertial gas-liquid separation and demisting, and special buffer flow stabilization treatment stages. Multi-stage filtration can intercept construction solid particles entrained in the airflow layer by layer, thoroughly removing everything from large-diameter impurities to fine dust, preventing solid impurities from damaging the core components of subsequent modules. Gas-liquid separation relies on the inertia of the airflow to separate and collect liquid water mist and oil mist from the airflow, preventing liquid substances from entering the heat storage and oxidation stages and affecting the reaction effect. The buffer flow stabilization structure can effectively suppress airflow and temperature fluctuations, ensuring that the output airflow always maintains a uniform and stable flow state, laying a stable operating foundation for all subsequent processing procedures.

[0037] The gradient heat storage module receives a stable airflow from the co-collection module. Inside the module, three sections of gradient composite heat storage bodies are arranged along the flue gas flow direction. These heat storage bodies are seamlessly connected by a sealed structure, forming a complete tiered heat storage system. Each of the three heat storage sections corresponds to a different temperature range, handling construction waste heat from 200℃ to 600℃. Construction waste heat serves as the sole heat source for the entire system, eliminating the need for external energy consumption and significantly reducing the system's energy costs. The system dynamically regulates the heat storage and release rhythm of the three heat storage sections through a gradient heat storage co-collection algorithm. The mathematical expression of the gradient heat storage co-collection algorithm is:

[0038]

[0039] in, The overall synergistic heat storage efficiency of the gradient heat storage body; , , These are the weighting coefficients for the low-temperature heat storage section, the medium-temperature heat storage section, and the high-temperature heat storage section in the three-section gradient composite heat storage body, respectively. The single-stage heat storage efficiency of the low-temperature heat storage section; This refers to the single-stage heat storage efficiency of the medium-temperature heat storage section. The single-stage heat storage efficiency of the high-temperature heat storage section; This is a correction factor for the grade of construction waste heat; To account for the load fluctuation coefficient during construction, the operating parameters of each stage of the heat storage body are adjusted according to the temperature distribution and fluctuations of the construction waste heat. The recovered medium- and low-temperature waste heat is gradually heated to create an 800℃-850℃ organic waste gas oxidation reaction space. This allows the organic waste gas to undergo complete oxidation and decomposition under high temperature conditions, achieving the harmless treatment of organic pollutants. Simultaneously, after the waste gas decomposition is complete, the three-stage heat storage body can also perform tiered heat recovery from the cooled flue gas, fully absorbing and storing the residual heat in the flue gas for reuse in the oxidation reaction, enabling the recycling of waste heat resources, maximizing energy efficiency, and adapting to the intermittent construction load of fixed work positions, always maintaining a stable temperature in the reaction space. Figure 3 As shown.

[0040] The flue gas conditioning module receives the high-temperature flue gas from the gradient heat storage module. It first uses a waste heat recovery heat exchange structure to gradually cool the flue gas, stabilizing its temperature within the 40℃-45℃ range. Simultaneously, it recovers residual heat from the flue gas to further supplement the system's energy supply. The cooled flue gas then enters a high-precision dust removal and deep purification stage. This stage filters out solid particles with a diameter of 1μm or larger and adsorbs and removes residual trace organic components and acidic impurities, preventing impurities from adhering to the carbon capture medium surface and reducing adsorption efficiency, while also preventing acidic impurities from corroding system pipelines and equipment. The purified flue gas then enters a dual-tower alternating deep drying stage. The process involves stabilizing the relative humidity of the flue gas below 10% and lowering the dew point temperature to -20℃ or below, completely eliminating the interference of humidity on carbon capture operations and ensuring the adsorption medium remains in optimal working condition. Finally, the process of buffering, stabilizing, and calibrating the operating conditions completes the flow stabilization and homogenization treatment, smoothing fluctuations in flue gas velocity, pressure, and component concentration, stabilizing the flue gas pressure within the range of 0.2MPa-0.3MPa, and standardizing the carbon dioxide concentration in the flue gas to the standard range of 15%-25%. This ensures that the temperature, humidity, pressure, and concentration of the flue gas all match the operating requirements of the carbon capture process, creating an optimally adapted operating condition for the carbon capture module and ensuring continuous and efficient carbon capture operations.

[0041] The carbon capture module performs carbon dioxide adsorption and purification on the conditioned flue gas. First, it separates nitrogen, oxygen, and trace impurities such as residual fine particles, organic components, and acidic substances from the flue gas. Relying on the selective adsorption characteristics of the adsorption medium, it continuously captures carbon dioxide from the flue gas until the adsorption capacity reaches 90%-95% of its design capacity, fully utilizing the adsorption capacity of the medium. Then, the desorption process is initiated, using a combination of heating and depressurization with nitrogen and oxygen purging to completely desorb and release the adsorbed carbon dioxide. Simultaneously, the adsorption medium is regenerated and recycled. The desorbed carbon dioxide, after conditioning, achieves a purity of over 99.5%, with nitrogen and oxygen content below 0.5% and no trace impurities remaining, fully meeting the requirements for ecological disposal and industrial reuse. Using standard methods, the system calculates the net carbon dioxide capture efficiency in real time through a carbon capture collaborative linkage algorithm. Based on the calculation results, it synchronously adjusts the adsorption and purification operation parameters, optimizes the adsorption and desorption rhythm, and utilizes the purified carbon dioxide through a closed-loop pipeline in two paths. The ecological disposal path transports the carbon dioxide to the ecological restoration area around the industrial park for vegetation carbon sink enhancement, saline-alkali land improvement, and microalgae cultivation, completing carbon dioxide fixation through natural ecological processes. The industrial reuse path transports the carbon dioxide to high carbon-consuming production enterprises within the park for use as raw materials for chemical synthesis, welding protective gas, and refrigerant. The two paths operate in synergy, relying on algorithms to precisely control the transport volume and rhythm, constructing a complete closed-loop operation structure for carbon resource utilization, transforming carbon dioxide from waste into a usable resource.

[0042] The dynamic control module collects various operating parameters from the four major modules—coordinated collection, gradient heat storage, flue gas conditioning, and carbon capture—throughout the entire process. Relying on the gradient heat storage coordinated algorithm and the carbon capture coordinated linkage algorithm, it coordinates the operating conditions and parameter coordination between the modules, adjusting the operating rhythm of each link in real time to form a closed-loop control mode for the entire system, maintaining a consistently efficient and coordinated operating state. Simultaneously, the module implements multi-level safety interlock monitoring of key operating parameters for each module. When the temperature of the gradient heat storage module exceeds the standard range, or when the carbon dioxide purity and capture efficiency of the carbon capture module fail to meet standards, an immediate trigger is established. The system employs a cascaded interlocking mechanism to suspend the operation of the corresponding module and initiate emergency control measures. When the humidity or pressure of the flue gas conditioning module exceeds the standard or the overall system loss is too high, a secondary interlocking mechanism is triggered, and the algorithm parameters are adjusted to issue an early warning. In case of emergencies such as pipeline leakage, equipment pressure and temperature exceeding limits, or adsorbent activity being too low, a tertiary interlocking mechanism is triggered, immediately cutting off the system feed and initiating the shutdown protection procedure. Simultaneously, the emergency emission device and alarm equipment are linked, and the interlocking status is fed back in real time throughout the process. This timely resolution of various operational risks ensures the long-term safe, stable, and controllable operation of the system in fixed workstation scenarios.

[0043] This embodiment applies the system to fixed workstations in industrial parks. Through a fully enclosed collection system, it achieves complete collection of waste heat and exhaust gas. Utilizing a gradient heat storage synergy algorithm, it achieves tiered utilization of waste heat and harmless decomposition of exhaust gas. Flue gas conditioning creates stable operating conditions suitable for carbon capture. Furthermore, a carbon capture synergy algorithm enables efficient purification of carbon dioxide and dual-path resource utilization. Dynamic control and multi-level interlocking ensure system stability and safety. The entire process requires no additional heat source, achieving deep synergy between exhaust gas treatment, waste heat utilization, and carbon emission reduction. It effectively solves the challenges of exhaust gas emissions and carbon control at fixed workstations, significantly improving the park's environmental governance and resource utilization levels, and providing reliable support for the low-carbon transformation of fixed work scenarios.

[0044] Example 2:

[0045] Example of Co-treatment of Organic Waste Gas for Pollution Reduction and Carbon Reduction at Mobile Workstations in Industrial Parks

[0046] This embodiment addresses the construction scenario of mobile workstations within industrial parks. It applies a collaborative treatment system for reducing pollution and carbon emissions from organic waste gas in industrial parks. Considering the flexible location, dispersed emissions, and large fluctuations in operating conditions of mobile workstations, the system's modules are optimized for operational adaptability. This enables the simultaneous collection, efficient treatment, and carbon resource utilization of medium- and high-temperature waste heat and organic waste gas throughout the entire process. The system maintains its synergistic effects of pollution reduction, carbon reduction, and resource utilization even in dynamic operating environments, meeting the environmental protection and low-carbon governance needs of mobile construction scenarios. Figure 2 As shown.

[0047] The collaborative collection module is adapted to the operational characteristics of mobile workstations, employing a sealed gas collection structure that can be adjusted synchronously with the working equipment. This structure can conform to the mobile work area in real time to form a local sealed space. As the construction equipment moves, the gas collection position and sealing range are adjusted synchronously, effectively containing all the medium-high temperature waste heat (200℃-600℃) and organic waste gas generated during construction within the sealed space. This completely prevents the unorganized escape of waste gas and heat during mobile operations. The collected mixed gas flow is converged through a flexible sealed channel, which remains sealed throughout, adapting to the pipeline adjustment requirements of mobile operations and preventing leakage during airflow transportation. This ensures that all waste heat and waste gas are completely delivered to subsequent treatment. The system provides a stable supply of air and heat to the front end. After the mixed airflow converges, it undergoes multi-stage filtration and dust removal, inertial gas-liquid separation and demisting, and special buffer flow stabilization treatment. Multi-stage filtration removes construction solid particles entrained in the airflow layer by layer, preventing impurities from causing wear and blockage to subsequent modules. Gas-liquid separation relies on airflow inertia to separate and collect liquid water mist and oil mist from the airflow, preventing liquid substances from affecting the heat storage and oxidation reaction. The buffer flow stabilization structure smooths out airflow fluctuations during mobile operations, making the originally unstable airflow uniform and smooth, ensuring that the output airflow conditions remain consistent, providing stable feeding conditions for subsequent processing steps, and adapting to the variable working conditions of mobile operations.

[0048] The gradient heat storage module receives a stable airflow from the collaborative collection module. Inside the module, three-section gradient composite heat storage bodies are arranged in a sealed, gapless manner along the flue gas flow direction, forming a complete tiered heat storage system. This system precisely absorbs the 200℃-600℃ construction waste heat generated during mobile operations, using construction waste heat as the sole heat source throughout the process, without relying on external energy supply, effectively reducing treatment costs in mobile operation scenarios. The system dynamically adapts to load fluctuations during mobile operations through a gradient heat storage collaborative algorithm, precisely controlling the heat storage and release rates of the three sections of the heat storage bodies based on changes in waste heat temperature and the rhythm of construction intervals. The heat distribution system gradually raises the temperature of the recovered medium- and high-temperature waste heat to 800℃-850℃, creating a stable oxidation reaction space for organic waste gas. This allows the organic waste gas to be completely oxidized and decomposed under high-temperature conditions, achieving the harmless treatment of organic pollutants. Simultaneously, after the waste gas is oxidized and decomposed, the three-stage heat storage body performs tiered heat recovery of the cooled flue gas, fully storing and recycling the residual heat in the flue gas for heating the oxidation reaction, maximizing the utilization of waste heat resources. Even if the operating conditions fluctuate frequently during mobile operations, the temperature of the oxidation reaction space can always be kept stable, ensuring that the decomposition effect of organic waste gas is not affected.

[0049] The flue gas conditioning module receives the high-temperature flue gas output from the gradient heat storage module. First, it uses a waste heat recovery heat exchange structure to stably reduce the flue gas temperature to 40℃-45℃. While cooling, it recovers waste heat from the flue gas to supplement the energy required for system operation, adapting to the energy-saving needs of mobile operation scenarios. The cooled flue gas then enters a high-precision dust removal and deep impurity removal stage, filtering out solid particles with a diameter of 1μm and above, and adsorbing and removing residual trace organic components and acidic impurities to prevent impurities from interfering with subsequent carbon capture operations and protect system equipment from corrosion. The purified flue gas then undergoes a dual-tower alternating deep drying process, reducing its relative... Humidity is controlled below 10%, and dew point temperature is reduced to -20℃ or below to eliminate the adverse effects of humidity on the carbon capture medium and keep the adsorption medium in a highly efficient adsorption state. Finally, the flow stabilization and homogenization treatment is completed through buffering and pressure stabilization and operating condition calibration to smooth the fluctuations in flue gas velocity, pressure, and concentration caused by mobile operation, stabilize the flue gas pressure at 0.2MPa-0.3MPa, and normalize the carbon dioxide concentration to 15%-25%. This ensures that all parameters of the flue gas fully meet the operating requirements of the carbon capture process, creating a stable operating condition for the carbon capture module and ensuring the continuous and efficient operation of carbon capture in dynamic scenarios.

[0050] The carbon capture module purifies the conditioned flue gas by adsorbing carbon dioxide. First, it separates nitrogen, oxygen, and trace impurities from the flue gas. Then, it captures carbon dioxide using the selective adsorption characteristics of the adsorption medium until the adsorption capacity reaches 90%-95% of the design capacity, fully utilizing the working capacity of the adsorption medium. Subsequently, desorption and medium regeneration are completed through heating, depressurization, and nitrogen and oxygen purging. The purity of the desorbed carbon dioxide reaches over 99.5%, meeting the standards for ecological disposal and industrial reuse. The system calculates the net carbon dioxide capture efficiency in real time using a carbon capture collaborative linkage algorithm. The mathematical expression of the carbon capture collaborative linkage algorithm is as follows:

The dynamic activity coefficient of the pressure swing adsorbent; The actual carbon dioxide concentration at the outlet of the gradient thermal storage module; Design concentration for carbon dioxide; To determine the overall loss coefficient of the system, the adsorption and purification parameters are adjusted according to the changes in the working conditions of mobile operations, and the dual-path transportation rhythm is optimized. The purified carbon dioxide is transported in a closed system. The ecological disposal path is used to enhance the carbon sink of vegetation around the park, improve saline-alkali land, and cultivate microalgae, thereby achieving carbon fixation with the help of the natural ecology. The industrial reuse path supplies high carbon-consuming enterprises in the park as chemical raw materials, welding shielding gas, and refrigerant. The two paths work together, and the algorithm enables precise control of the transportation volume, thus constructing a closed-loop structure for carbon resource utilization, allowing carbon dioxide to be recycled and utilized even in mobile operation scenarios.

[0053] The dynamic control module continuously collects the operating parameters of the entire system. Relying on the gradient thermal storage collaborative algorithm and the carbon capture collaborative linkage algorithm, it coordinates the various modules to adapt to the dynamic working conditions of mobile operations, adjusts the operating parameters of each link in real time, and realizes closed-loop control of the entire system, so that each module can maintain high efficiency and collaboration even in dynamic environments. At the same time, the module activates a multi-level safety interlock mechanism to monitor key indicators such as gradient thermal storage temperature, flue gas humidity and pressure, carbon dioxide purity, system pressure, pipeline sealing, and adsorbent activity in real time. After triggering the corresponding level of interlock, it promptly executes operations such as parameter adjustment, early warning, pressure relief, feed cut-off, and shutdown protection, quickly resolving risks such as operating condition fluctuations, pipeline deviation, and leakage that are prone to occur in mobile operation scenarios. The module provides real-time feedback on the operating status throughout the process, ensuring that the system always maintains safe, stable, and efficient operation in the complex environment of mobile operations, and successfully achieves the goals of pollution reduction, carbon reduction, and resource synergistic utilization.

[0054] This embodiment deploys a collaborative processing system for mobile workstations in industrial parks. Its followable, closed-loop gas collection structure adapts to dynamic operation characteristics, enabling the collection of waste heat and gas without leakage. A gradient heat storage collaborative algorithm adapts to fluctuations in operating conditions, completing waste heat utilization and waste gas decomposition. After flue gas conditioning to stabilize carbon capture conditions, a carbon capture collaborative linkage algorithm achieves closed-loop utilization of carbon dioxide resources. Dynamic control and multi-level interlocking mitigate the risks of dynamic operations. The system maintains high efficiency even in mobile scenarios, simultaneously achieving pollution reduction, carbon reduction, and resource recovery goals. It perfectly adapts to the governance needs of mobile operations, providing a feasible solution for low-carbon governance across all scenarios in industrial parks.
