Description

[0002] With the acceleration of industrialization and urbanization, volatile organic compounds (VOCs) have become one of the important sources of air pollution. The emission of VOCs waste gas is more prominent. It has the characteristics of multiple emission sources, multiple pollutants and high toxicity, which seriously pollutes the ambient atmosphere.

[0003] The common method is "nitrogen sealing + introduction of negative pressure system", in which nitrogen sealing forms a protective barrier by injecting nitrogen to prevent the leakage of VOCs waste gas, and the introduction of negative pressure system is to further prevent waste gas leakage by creating a negative pressure environment. However, it is difficult to achieve stable and efficient treatment due to the large nitrogen consumption, obvious pressure fluctuations and possible secondary leakage problems. The "multi-stage washing + activated carbon adsorption and desorption" method has a better purification effect, but due to the limited adsorption capacity of activated carbon, and if the activated carbon after adsorption saturation is not handled properly, it may become a new source of pollution. At the same time, in complex scenarios with multiple emission sources, the reliability of VOCs waste gas treatment will be further reduced.

[0013] Embodiment 1

[0014] The present application is described in detail below with reference to the accompanying drawings. Figure 1 As shown, the present application provides a VOCs safety management method, wherein the method comprises:

[0015] S10: receiving a VOCs waste gas treatment request, which includes a leakage emission mark, a maintenance emission mark, and an overpressure emission mark; S20: parsing the VOCs waste gas treatment request and configuring a pipeline closure self-inspection rule, which is used to prevent secondary leakage of VOCs waste gas; S30: activating the pipeline closure self-inspection rule, and triggering the VOCs waste gas treatment process when the closure self-inspection passes.

[0016] Specifically, VOCs waste gas treatment request refers to the request for the treatment of volatile organic compound waste gas generated in the industrial production process, which is different due to different emission situations, including leakage emission, maintenance emission and overpressure emission. Among them, the leakage emission mark is used to identify VOCs waste gas emission events caused by equipment or pipeline leakage; the maintenance emission mark is used to identify VOCs waste gas emission events caused by equipment maintenance; the overpressure emission mark is used to identify emission events caused by system pressure exceeding the safety threshold, also known as emergency emission; the pipeline closure self-inspection rules refer to a series of automated detection and response mechanisms used to ensure the closure of the pipeline system and prevent leakage of VOCs waste gas.

[0017] Execution steps: Receive VOCs waste gas treatment requests from the site. The VOCs waste gas treatment requests contain different types of emission tags so that the system can identify the specific circumstances of the emissions; parse the received requests, identify the specific emission types, and configure the corresponding pipeline closure self-inspection rules accordingly; configure a set of pipeline closure self-inspection rules based on the parsing results. The pipeline closure self-inspection rules are designed to prevent secondary leakage of VOCs waste gas and ensure the safety of waste gas treatment; after the configuration is completed, the pipeline closure self-inspection rules will be activated to start testing the closure of the pipeline system; when the pipeline closure self-inspection passes, it indicates that the pipeline system is closed, triggering the VOCs waste gas treatment process and entering the actual waste gas treatment stage.

[0018] In the above steps, through effective request reception and analysis, as well as pipeline closure self-inspection, secondary leakage of VOCs waste gas can be prevented, environmental pollution and safety risks can be reduced, and the safety and timeliness of VOCs waste gas treatment can be ensured.

[0019] S40: Introduce emission safety standards, which include emission concentration thresholds and emission rate thresholds; S50: Based on the VOCs waste gas treatment process, in a pipeline collection and post-processing manner, combined with the emission safety standards, conduct safety management and establish a self-organizing framework, which is used to manage multiple VOCs treatment projects; S60: Mark the sources and ends of multiple VOCs treatment projects in the self-organizing framework, and set up a collaborative management strategy in a full-process management manner, which is used to respond to VOCs waste gas treatment requests.

[0020] Specifically, the emission safety standard refers to the upper limit of the concentration and rate of VOCs emissions set to ensure the safety of the environment and personnel; the emission concentration threshold refers to the maximum allowable concentration of VOCs emitted into the atmosphere, exceeding this value may cause harm to the environment or health; the emission rate threshold refers to the maximum allowable rate of VOCs emitted into the atmosphere, that is, the maximum amount of emissions allowed per unit time.

[0021] The pipeline collection and post-treatment method refers to the method of collecting VOCs waste gas through a pipeline system and then transporting it to a treatment facility for purification; the self-organizing framework refers to a system framework that can self-manage and self-regulate, and is used to coordinate and manage multiple VOCs control projects; the full-process control method refers to the implementation of continuous management and control strategies for the entire process from the source of VOCs waste gas generation to the end; the collaborative control strategy refers to a strategy in which multiple control projects collaborate with each other to jointly respond to VOCs waste gas control requests.

[0022] Implementation steps: In the VOCs waste gas treatment process, introduce emission concentration thresholds and emission rate thresholds to ensure that the VOCs emissions after treatment comply with environmental regulations and safety requirements; use a pipeline system to collect VOCs waste gas, and then transport it to the treatment facility for purification, so as to effectively control VOCs emissions and reduce the impact on the environment; create a self-organizing framework to manage multiple VOCs treatment projects to improve treatment efficiency and response speed; in the self-organizing framework, clearly mark the source (waste gas generation point) and end (waste gas treatment point) of each VOCs treatment project to implement full-process treatment; set up a collaborative treatment strategy based on the marked source and end to ensure that each treatment project can collaborate with each other and jointly respond to VOCs waste gas treatment requests.

[0023] In the above steps, by introducing emission safety standards, it can be ensured that the VOCs emissions after treatment will not cause harm to the environment and health. The establishment of a self-organizing framework and collaborative governance strategy enables multiple governance projects to collaborate efficiently and achieve full-process VOCs governance, thereby improving the flexibility and response speed of governance, thereby more effectively controlling VOCs emissions, reducing environmental pollution, and ensuring the compliance, safety and effectiveness of VOCs waste gas treatment.

[0024] Furthermore, the VOCs waste gas treatment request is parsed and pipeline closure self-check rules are configured. The application method includes:

[0025] S21: Connect to the sending end of the VOCs waste gas treatment request and receive the preset emission cycle; S22: Obtain the pipeline material information, and compare it with the pipeline structure map to determine the leakage risk point and leakage risk level; S23: Through the leakage risk point and leakage risk level, combined with the preset emission cycle and emission time window, the pipeline closure self-inspection rules are differentiated.

[0026] Specifically, the sending end refers to the initiator of the VOCs waste gas treatment request, usually the industrial equipment or system that emits VOCs waste gas; the preset emission cycle refers to the time interval or cycle of VOCs waste gas emissions set in advance according to the production plan or operating procedures; the pipeline material information refers to the type, thickness, corrosion resistance and other information related to the pipeline material; the pipeline structure map is a detailed diagram that describes the structural features such as pipeline layout, connection method and pipeline size; the leakage risk point refers to the specific location in the pipeline system where leakage may occur; the leakage risk level refers to the classification of risk points according to the potential impact and probability of occurrence of the leakage risk point; differentiated adjustment refers to the customized adjustment of the pipeline closure self-inspection rules according to the specific situation.

[0027] Execution steps: Establish a connection with the sender of the VOCs waste gas treatment request to receive data about the preset emission cycle, including the schedule and cycle of the emission; collect material information of the pipeline; combine the pipeline material information and the pipeline structure map to identify possible leakage risk points, and classify multiple leakage risk points according to the severity of the risk and the possibility of occurrence; according to the leakage risk point and risk level, the pipeline closure self-inspection rules will be differentiated and adjusted in combination with the preset emission cycle and emission time window, which means that for high-risk areas, the self-inspection rules may be more stringent or frequent, while for low-risk areas, they may be appropriately relaxed.

[0028] In the above steps, through in-depth understanding and risk assessment of the pipeline system, self-inspection rules can be formulated and adjusted more accurately, so as to more effectively prevent and respond to the leakage of VOCs exhaust gas, ensure the safety and reliability of the entire treatment process, and improve the safety of the pipeline system and the efficiency of the treatment process.

[0029] Furthermore, by comparing the pipeline structure map, the leakage risk point and leakage risk level are determined. The application method includes:

[0030] S221: Based on the leakage emission mark corresponding to the VOCs waste gas treatment request, set the leakage emission scenario; S222: Based on the leakage emission scenario, introduce the safety storage standard to identify potential safety hazards; S223: Through the potential safety hazards, make positive and flexible adjustments to the leakage risk points and leakage risk levels.

[0031] Specifically, the leakage emission scenario refers to a simulated or actual emission scenario constructed based on the specific conditions and environment of the leakage emission mark in the VOCs waste gas treatment request; the safe storage standard involves the safety specifications that should be followed during the storage of VOCs waste gas, including the material, capacity, pressure limit, etc. of the storage container to ensure the safety of the storage process; potential safety hazards may exist in the VOCs waste gas treatment process. If the risks corresponding to potential safety hazards are not identified and controlled, they may lead to safety accidents; positive elastic allocation refers to the adjustment of leakage risk points and risk levels based on the identified potential safety hazards to improve the safety and adaptability of the system.

[0032] Implementation steps: Based on the leakage emission mark in the VOCs waste gas treatment request, construct a specific leakage emission scenario. The leakage emission scenario will simulate the actual leakage situation, including the location of the leakage, the possible leakage amount and the environmental conditions at the time of leakage; based on the leakage emission scenario, introduce safe storage standards, conduct a safety assessment on the storage and treatment process of VOCs waste gas, and identify possible safety hazards; based on the identified potential safety hazards, adjust the leakage risk points and risk levels. The adjustment is positive, which means increasing attention and preventive measures on high-risk points and improving the adaptability and safety of the system.

[0033] In the above steps, by simulating leakage emission scenarios and identifying potential safety hazards, the leakage risk points and risk levels can be more accurately assessed and adjusted, thereby more effectively preventing and responding to VOCs waste gas leakage incidents, ensuring the safety and efficiency of the entire treatment process, and improving the safety and adaptability of the VOCs waste gas treatment process.

[0034] Furthermore, the present application method also includes:

[0035] S224: Based on the leakage emission scenario, identify the leakage emission peak period associated with the potential safety hazard; S225: Based on the leakage emission peak period, filter to obtain the leakage emission low period, and perform reverse elastic adjustment of the leakage risk points and leakage risk levels.

[0036] Specifically, the period of high incidence of leakage and emission refers to the period within a specific time period when VOCs leakage and emission incidents frequently occur due to operating conditions, environmental factors or other reasons; the period of low incidence of leakage and emission is the opposite of the period of high incidence, and refers to the period when VOCs leakage and emission incidents rarely occur; reverse elastic allocation refers to the reverse adjustment of leakage risk points and risk levels according to the periods of high and low incidence of leakage emissions, so as to optimize resource allocation and monitoring efforts.

[0037] Implementation steps: Through in-depth analysis of leakage emission scenarios, combined with historical data, operation logs and environmental monitoring data, identify time periods when VOCs leakage emission incidents frequently occur. The high incidence period of leakage emission is related to specific operating conditions, equipment use frequency or external environmental factors; after identifying the high incidence period, determine the period when leakage emission incidents rarely occur through comparative analysis. The low incidence period of leakage emission requires fewer monitoring resources or non-critical maintenance work can be arranged; according to the identification results of the high incidence period of leakage emission and the low incidence period of leakage emission, reversely adjust the leakage risk points and risk levels; during the high incidence period of leakage emission, it may be necessary to increase monitoring efforts and emergency preparedness; while during the high incidence period of leakage emission, monitoring resources can be appropriately reduced to optimize resource allocation.

[0038] In the above steps, by identifying and allocating the high-incidence and low-incidence periods of leakage emissions, more adequate safety guarantees can be provided during the high-incidence periods, and resources can be reasonably allocated during the low-incidence periods, so that the VOCs control plan can be implemented more flexibly. This helps to optimize the control process, reduce unnecessary waste of resources, and improve the efficiency of VOCs waste gas control while ensuring safety.

[0039] Furthermore, the sources and ends of multiple VOCs governance projects in the self-organizing framework are marked, and a collaborative governance strategy is set in a full-process governance manner. The application method includes:

[0040] S61: In the leakage emission scenario, according to the sources of multiple VOCs control projects in the self-organizing framework, a multi-layer casing structure is set, and each layer of casing of the multi-layer casing structure has a gap area; S62: Based on the multi-layer casing structure, a leakage diffusion sequence is determined; S63: Based on the leakage diffusion sequence, a first-level control strategy is set in a full-process control manner.

[0041] Specifically, a multi-layer casing structure refers to a structure composed of multiple layers of pipes, with a certain spatial gap between each layer of pipes. The design of the gap area between each layer of casing can be used to control and limit the leakage and diffusion of VOCs; the gap area refers to the space between two adjacent layers of casing in the multi-layer casing structure. The gap area can be used to detect and isolate leaks, or serve as a safety buffer zone; the leakage diffusion sequence refers to the path and order of VOCs diffusing from the leakage point to the outside when a leak occurs, which usually depends on the design of the multi-layer casing structure and the physical properties of VOCs; the first-layer control strategy refers to the control measures in the innermost layer or closest to the leakage source in the multi-layer casing structure, which is the first line of defense against leakage incidents.

[0042] Implementation steps: According to the sources of multiple VOCs treatment projects in the self-organizing framework, a multi-layer casing structure is designed and set up. There is a gap area between each layer of casing in the multi-layer casing structure to isolate and control the leakage of VOCs; based on the design of the multi-layer casing structure, the diffusion path and sequence of VOCs in the event of a leak are analyzed and determined, including the process of VOCs starting from the leak point, passing through the gap area, and reaching the next layer of casing; according to the leakage diffusion sequence, the first-level control strategy is formulated and implemented, including installing leak detection sensors in the innermost casing, setting up emergency shut-off valves, or equipping with a rapid response collection and treatment system.

[0043] In the above steps, by setting up a multi-layer casing structure and gap areas, the spread of VOCs can be quickly isolated and controlled when a leak occurs, reducing the impact on the environment and personnel. At the same time, by determining the leak diffusion sequence and setting the first-level control strategy, quick action can be taken at the early stage of the leak to prevent the leak from expanding, ensuring the stability and safety of the entire VOCs treatment process, enhancing the ability to control VOCs leaks, and improving the safety and effectiveness of the treatment process.

[0044] Furthermore, the present application method also includes:

[0045] S64: In the leakage emission scenario, an air volume regulation structure is set according to the ends of multiple VOCs control projects in the self-organizing framework; S65: Based on the air volume regulation structure, an air volume allocation sequence is determined; S66: Based on the air volume allocation sequence, the Mth layer control strategy is set in a full-process control manner.

[0046] Specifically, the air volume regulation structure refers to the equipment or system used to regulate and manage the flow of gas, which can control the flow and velocity of the gas to adapt to different processing requirements; the air volume distribution sequence refers to the distribution plan of the gas flow in different stages or different processing units based on the design and operating conditions of the air volume regulation structure; the M-th layer control strategy refers to the control measures at the end or last stage in the entire multi-layer control system.

[0047] Execution steps: At the end of the VOCs treatment project, according to the requirements of the self-organizing framework, install and configure the air volume adjustment structure, which can be valves, fans, flow meters, etc., to accurately control the flow and velocity of the gas; based on the function of the air volume adjustment structure and the specific needs of the treatment project, formulate an air volume distribution sequence. The air volume distribution sequence determines the specific distribution of gas flow in different treatment stages or different treatment units to ensure the efficiency and effectiveness of the entire treatment process; according to the air volume distribution sequence, formulate and implement the M-th layer control strategy, including setting the final emission monitoring point in the terminal treatment unit, equipping emission purification equipment, or implementing the final emission safety inspection.

[0048] In the above steps, by setting the air volume adjustment structure and determining the air volume distribution sequence, the gas flow can be accurately controlled and the treatment process can be optimized. At the same time, by setting the M-th layer control strategy, key control measures can be implemented in the final stage of the treatment process to ensure that the final emissions of VOCs meet safety and environmental protection standards, ensure the reliability and effectiveness of the entire treatment system, ensure the end treatment effect of the VOCs treatment process, and improve the efficiency and safety of the entire treatment system.

[0049] Furthermore, the present application method also includes:

[0050] S67: Construct a multi-level collaborative control model based on the first-level control strategy corresponding to the source of multiple VOCs control projects in the self-organizing framework to the M-th-level control strategy corresponding to the end of multiple VOCs control projects in the self-organizing framework; S68: From the source and end of multiple VOCs control projects in the self-organizing framework, fluid mechanics simulation analysis is used to formulate multiple exhaust gas flow paths; S69: Based on the multi-level collaborative control model, the multiple exhaust gas flow paths are optimized and adjusted, and a collaborative control strategy is set in combination with the leakage diffusion sequence and the air volume distribution sequence.

[0051] Specifically, the multi-level collaborative control model refers to a model that comprehensively considers all control strategies from the source to the end, aiming to achieve coordination and optimization of the entire VOCs control process; fluid mechanics simulation analysis uses the principles of fluid mechanics and mathematical models to predict and analyze the behavior and characteristics of gas flow through computer simulation; the exhaust gas flow path refers to the path that VOCs pass through during the entire flow process from source emission to final treatment; the collaborative control strategy refers to a control strategy that comprehensively considers the leakage diffusion sequence and air volume distribution sequence, as well as the multi-level control model, to achieve optimization of the entire control process.

[0052] Execution steps: Combine the first-level control strategy corresponding to the source of multiple VOCs treatment projects in the self-organizing framework and the M-th level control strategy corresponding to the end to build a comprehensive collaborative control model. The multi-level collaborative control model will cover all relevant control points and treatment stages to ensure the coordination and effectiveness of the entire treatment process; use the principles of fluid mechanics to analyze the flow characteristics of VOCs through computer simulation to formulate multiple possible exhaust gas flow paths, which will take into account factors such as pipeline layout, airflow resistance, and pressure changes.

[0053] Based on the multi-level collaborative control model, the proposed exhaust gas flow path is optimized and adjusted, including adjusting the pipeline layout, improving the control strategy or adding new treatment units to improve the efficiency and effectiveness of the entire system; combined with the leakage diffusion sequence and the air volume distribution sequence, as well as the optimized exhaust gas flow path, a collaborative governance strategy is set up. The collaborative governance strategy will ensure a rapid response in the event of a leak and achieve effective VOCs control under normal operating conditions.

[0054] In the above steps, by constructing a multi-level collaborative control model and conducting fluid mechanics simulation analysis, the flow of VOCs can be predicted and controlled more accurately, thereby optimizing the control effect. Setting a collaborative control strategy can ensure effective VOCs control under different circumstances, improve the adaptability and reliability of the entire system, and ensure the optimization and coordination of the entire VOCs control process.

[0055] In summary, the beneficial effects of the embodiments of the present application are:
