Description

Technical Field

[0001] The present invention relates to the field of industrial safety monitoring and automatic control, and particularly to a real-time monitoring and explosion-proof linkage system for dust and volatile organic compounds in a renewable resource processing center. Background Art

[0002] In recent years, with the development of the renewable resource industry towards scale and intensification, modern renewable resource processing centers have become the mainstream of the industry. However, in the core processes such as crushing, sorting, and packing of various materials such as waste plastics, waste textiles, waste paper, and electronic waste, a large amount of combustible dust (such as plastic particles, fiber dust, metal dust) and organic compounds volatilized from the waste are inevitably generated. These substances are easily mixed with air in a confined space, forming an explosive environment, which is a major safety hazard that is widespread and seriously underestimated in the industry. Traditionally, the processing center mainly relies on manual inspections and regular dust cleaning to prevent risks, but this method has serious lag and uncertainty, and cannot provide real-time quantitative early warning of explosion risks, resulting in frequent fires and even dust explosion accidents, causing serious personnel and property losses.

[0003] To address the above risks, although independent dust concentration monitors or VOCs gas detectors have been introduced in the prior art, these devices usually have single functions and are independent of each other. Their monitoring data is often only used for on-site display or over-limit alarm, and it is difficult to form an efficient and fast automated linkage with the active safety facilities such as ventilation, dust removal, and fire protection in the processing center. In addition, the environment in the processing center is harsh, and the sensor probes are easily contaminated and malfunction, resulting in high maintenance and calibration costs. Therefore, currently, in terms of production safety, renewable resource processing centers generally lack a systematic solution that integrates real-time, accurate, multi-parameter monitoring and automatic, reliable, and fast linkage disposal, and it is difficult to meet the urgent needs of modern and intelligent factories for the level of intrinsic safety. Summary of the Invention

[0004] The present invention specifically relates to a real-time monitoring and explosion-proof linkage system for dust and volatile organic compounds in a renewable resource processing center, aiming to collect the dust and VOCs concentrations at multiple risk points in real time through distributed monitoring modules, and combine the intelligent analysis of the central control module to achieve all-round and uninterrupted perception of explosion risks, fundamentally changing the lagging mode that traditionally relies on manual inspections. To achieve the above object, the specific technical solution of a real-time monitoring and explosion-proof linkage system for dust and volatile organic compounds in a renewable resource processing center of the present invention is as follows: A real-time monitoring and explosion-proof linkage system for dust and volatile organic compounds in a renewable resource processing center, comprising: The monitoring module is distributed across multiple risk points within the processing center to collect dust concentration data and VOCs concentration data at each point in real time. The linkage execution module is set at the risk points within the processing center. The linkage execution module includes a ventilation device, a misting dust suppression device, an equipment power controller, and an audible and visual alarm. The central control module is communicatively connected to the monitoring module and the linkage execution module, and is configured as follows: Receive and process concentration data sent by the monitoring module; The concentration data is compared with a preset concentration threshold to determine the risk level; Based on the risk level, a corresponding hierarchical linkage control command is sent to the linkage execution module.

[0005] Furthermore, the monitoring module includes a dust concentration sensor and a VOCs gas sensor.

[0006] Furthermore, the monitoring module also includes a self-cleaning unit for protecting the sensor probe, the self-cleaning unit including an air curtain generator arranged around the probe.

[0007] Furthermore, the preset concentration thresholds include a first warning threshold, a second action threshold, and a third danger threshold; The central control module is configured as follows: When the concentration data reaches the first warning threshold, a first-level linkage is triggered, controlling the audible and visual alarm to issue a warning. When the concentration data reaches the second action threshold, a secondary linkage is triggered, activating the ventilation device and the atomized dust suppression device. When the concentration data reaches the third danger threshold, a three-level linkage is triggered, and the power supply to the production equipment in the corresponding risk area is cut off through the equipment power controller.

[0008] Furthermore, the central control module is also configured to: continuously monitor concentration data after triggering a level 2 or level 3 linkage, and automatically deactivate the linkage and restore the operation of the production equipment after the concentration data falls below the safety threshold and remains there for a preset time.

[0009] Furthermore, it also includes an environmental parameter acquisition module for collecting temperature and humidity data at risk points; when determining the risk level, the central control module combines the temperature and humidity data to perform compensation calculations on the concentration data.

[0010] Furthermore, the ventilation device includes a sparkless fan, and the atomizing dust suppression device includes an intrinsically safe solenoid valve.

[0011] Further, the central control module is communicatively connected to a cloud server and a remote monitoring terminal, and is configured to upload concentration data, alarm records, and linkage event logs, and receive control instructions from the remote monitoring terminal.

[0012] Further, the multiple risk points include at least one of a crusher feed inlet, a crushing discharge area, a baler working area, and a material temporary storage warehouse.

[0013] Further, the central control module further includes an early warning analysis unit, which is configured to predict the trend and time when the concentration reaches the preset concentration threshold based on the real-time change trend and historical data of the concentration data through a preset algorithm, and generate early warning information.

[0014] Compared with the prior art, the present invention realizes all-round and uninterrupted perception of explosion risks by using the distributed monitoring modules to collect the dust and VOCs concentrations at multiple risk points in real time and combining with the intelligent analysis of the central control module, fundamentally changing the lagging mode that traditionally relies on manual inspections. The system automatically starts hierarchical linkage responses based on preset multi-level concentration thresholds, forming a complete, fast, and automated safety protection closed-loop from audible and visual warnings, automatic startup of ventilation and dust suppression equipment to emergency power-off of equipment, greatly improving the speed and reliability of emergency responses, effectively curbing the苗头 of accidents, and ensuring the safety of personnel and facilities. In addition, the self-cleaning unit of the sensor probe in the system ensures the long-term stability and accuracy of monitoring data; the environmental parameter compensation mechanism improves the accuracy of risk judgment; the explosion-proof design of key actuating components (such as sparkless fans and intrinsically safe solenoid valves) eliminates the risk of secondary ignition; the remote monitoring and early warning analysis functions realize the digitization and forward-looking of safety management. The system finally constructs an intrinsically safe solution integrating real-time monitoring, intelligent judgment, automatic disposal, and remote management, significantly improving the work safety level and intelligent operation ability of the renewable resource processing center. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a flowchart of the working principle of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the following provides a detailed and specific description of the present invention in combination with preferred embodiments and the appended Figure 1 , which is only used to explain the present invention and is not used to limit the protection scope of the present invention.

[0017] Embodiment 1 This embodiment details a real-time monitoring and explosion-proof linkage system for dust and volatile organic compounds (VOCs) in a recycling center, comprising: a monitoring module, which is distributed across multiple risk points within the center to collect real-time dust and VOC concentration data at each point; a linkage execution module, also located at the risk points within the center, comprising a ventilation device, a misting dust suppression device, an equipment power controller, and an audible and visual alarm; and a central control module, communicatively connected to both the monitoring and linkage execution modules, configured to: receive and process concentration data sent by the monitoring module; compare the concentration data with a preset concentration threshold to determine the risk level; and, based on the risk level, send corresponding graded linkage control commands to the linkage execution module. In the core embodiment of this invention, the system is deployed in key areas of the recycling center, such as the crushing workshop, sorting line, and packaging area. The monitoring module consists of multiple monitoring nodes, which are distributed and fixedly installed at representative risk points such as ceiling columns and above equipment in the workshop. Each node is connected to the central control cabinet via an industrial bus network. Each terminal of the linkage execution module is installed near the corresponding risk point: explosion-proof audible and visual alarms are installed in easily observable locations, explosion-proof axial flow fans are installed on walls or roofs, the nozzle arrays of the atomizing dust suppression device are distributed above the dust-generating points, and the equipment power controller is connected to the main power supply circuit of the corresponding area's production equipment. The central control module consists of an industrial control computer, a programmable logic controller (PLC), and corresponding control software installed in the central control room. Its workflow is as follows: it continuously receives real-time concentration data streams from each monitoring node, internally compares the data with multi-level thresholds pre-set according to safety standards, performs logical operations, dynamically determines the risk level (safe, warning, dangerous, etc.) of each point, and sends control commands containing specific address codes to the corresponding PLC output modules based on different level determination results, thereby driving the audible and visual alarms, fans, sprayers, or power-off circuits at the designated points. This embodiment constructs a complete automated safety closed loop from "perception-decision-execution". Distributed monitoring achieves comprehensive coverage of risks throughout the workshop, overcoming the intermittency and blind spots of manual inspections. The centralized intelligent processing of the central control module enables rapid analysis and unified decision-making of complex data, ensuring the consistency and optimality of response strategies. The hierarchical linkage design ensures precise and orderly system responses, avoiding excessive interference with the production process. The entire system upgrades the previously decentralized, experience-dependent safety management into an integrated, automated, and intelligent proactive safety protection system, fundamentally improving the inherent safety level of the processing center.

[0018] In this embodiment, the specific sensing units of the monitoring module are further clarified. The dust concentration sensor preferably employs an online monitoring instrument based on the principle of laser backscattering. It emits a laser beam into the air being measured and inverts the mass concentration by measuring the intensity of light scattered by suspended dust particles, featuring fast response and a wide measurement range. The VOCs gas sensor preferably employs a photoionization (PID) sensor, which utilizes an ultraviolet lamp to ionize gas molecules and measures the concentration of total volatile organic compounds by detecting the ion current. It exhibits high sensitivity and good linear response for most VOCs. These two types of sensors are integrated and packaged in an explosion-proof housing, forming an independent monitoring node, connected to the system through a unified power supply and communication interface. Clarifying the core sensing devices of the monitoring module makes the solution more feasible. Laser scattering method offers high accuracy and stability in dust measurement, suitable for continuous monitoring in industrial settings. PID technology has a broad-spectrum response to a wide variety of VOCs, making it ideal for handling VOCs monitoring needs with complex central components. The combination of these two technologies enables the acquisition of dual key parameters—dust explosion parameters (concentration) and the risk of toxic, hazardous, and flammable gases—providing a reliable data foundation for accurate risk assessment. The integrated design facilitates installation, calibration, and maintenance.

[0019] In this embodiment, to address the issue of sensor data inaccuracy caused by contamination in harsh industrial environments, a self-cleaning unit is added to each monitoring node. The core of this unit is a ring-shaped air curtain generator, precisely surrounding the sampling window or air inlet of the dust and VOCs sensor probe. This device is connected to a filtered and dried clean compressed air pipeline and is triggered by a central control module according to a preset cycle (e.g., once per hour) or based on the degree of sensor data drift. During operation, the solenoid valve opens, and clean compressed air is ejected through micro-holes on the ring-shaped device, forming a uniform and stable conical air curtain barrier on the probe surface. This air curtain continuously blows away dust and oil mist that may adhere to the probe surface and isolates contaminated air when not sampling. The self-cleaning unit design directly addresses the pain point of long-term stable operation of sensing equipment in industrial settings. The surrounding air curtain forms a physical isolation barrier, effectively preventing the deposition of contaminants on the sensitive probe surface, greatly extending the sensor's maintenance cycle and lifespan. Periodic or intelligently triggered cleaning mechanisms ensure that the sensor probes are always in good working condition, thereby guaranteeing the long-term reliability and accuracy of monitoring data, avoiding false alarms or missed alarms caused by sensor contamination, and reducing the overall maintenance cost of the system.

[0020] In this embodiment, the core control logic of the system—the three-level linkage response mechanism—is concretized. The preset concentration thresholds are based on national standards such as the lower explosive limit (LEL) of dust, occupational exposure limits for VOCs, and explosion limits, and are fine-tuned according to the characteristics of the on-site processes. For example, a dust concentration of 20% of the LEL is set as the first warning threshold, 40% as the second action threshold, and 60% as the third danger threshold. The software logic within the central control module continuously compares data: when any monitoring point's data reaches the first threshold, a command is immediately sent to the audible and visual alarm at that point, issuing an audible and visual warning to alert on-site personnel and prompt inspection. If the concentration continues to rise to the second threshold, the system automatically activates all explosion-proof ventilation fans in the area to enhance air exchange and simultaneously activates the high-pressure spray dust suppression device to reduce the concentration of harmful substances in the air. When the concentration surges to the most dangerous third threshold, indicating an immediate risk of combustion and explosion, the system unconditionally sends an emergency stop command to the power controller of the relevant equipment, forcibly cutting off the power supply to potential ignition sources such as crushers and conveyor belts, eliminating the ignition conditions at the source. The three-tiered linkage mechanism embodies the gradual, intelligent, and mandatory nature of safety response. Early warning levels provide valuable buffer time for manual intervention. Automatic ventilation and dust suppression at the action level serve as the first automated line of defense for proactive risk intervention. Mandatory power cuts at the danger level are the final and most direct and effective technical means to prevent accidents. This tiered response strategy avoids unnecessary disruption to production caused by overreactions to minor anomalies, while ensuring the most decisive measures are taken in truly dangerous situations, achieving an optimal balance between safety and efficiency. The logic is clear, and the response levels are distinct.

[0021] This embodiment further refines the recovery logic after the linkage response. After the system executes a Level 2 (ventilation and dust suppression) or Level 3 (emergency power failure) linkage, the central control module does not stop working but continues to collect concentration data from relevant points at a higher frequency. The system sets a "safety threshold" below the action threshold and a "continuous safe time" (e.g., 5 minutes). Only when the monitoring data indicates that the concentration has dropped below the safety threshold and has been stably maintained at this low concentration for the preset duration, does the central control module determine that the risk has been truly eliminated. Subsequently, it automatically sends a reset command to the relevant actuators: stop the ventilation and dust suppression device, or close the circuit breaker of the equipment power controller to restore power to the production equipment. The entire process does not require manual reset; the system automatically completes the entire process management from alarm to recovery. This automatic recovery mechanism greatly improves the system's intelligence and availability. It avoids the cumbersome and delayed process of requiring manual on-site confirmation and reset after a brief increase and decrease in risk, ensuring that production can automatically resume as soon as safety conditions are met, reducing unnecessary downtime. The continuous monitoring and delayed recovery judgment logic effectively prevents frequent system start-ups and shutdowns caused by short-term concentration fluctuations, ensuring the safety and reliability of recovery timing, and realizing fully automated closed-loop management from risk warning and emergency response to state recovery.

[0022] In this embodiment, the system integrates temperature and humidity sensors into the monitoring nodes, forming an environmental parameter acquisition module. The software algorithm of the central control module incorporates a compensation model. For example, humidity data is used to compensate for the readings of the dust concentration sensor, as high humidity may cause dust agglomeration, affecting the measurement values ​​of the laser scattering method; temperature data is used to compensate for the readings of the PID sensor, as the sensor sensitivity changes with temperature. When determining the risk level, the central processor does not directly use the original concentration readings, but instead calls the compensation algorithm to calculate a "standard state concentration value" after environmental factor correction, using the original data and the current temperature and humidity data together. This corrected value is then used as the basis for comparison with a preset threshold. The introduction of environmental parameter compensation greatly improves the scientific nature and accuracy of risk assessment. It overcomes the influence of complex environmental factors in industrial sites on the measurement accuracy of sensors and reduces the distortion of monitoring data caused by weather changes, seasonal changes, or process fluctuations. This makes risk level assessment based on concentration data more reliable, avoids false alarms caused by environmental interference (such as high dust readings due to high humidity on rainy days), and prevents underreporting of real risks due to low readings in adverse environments, making the warning and linkage actions of the entire system more accurate and reliable.

[0023] In this embodiment, to ensure the absolute safety of the linkage execution module itself in an explosive hazardous environment, its key components have undergone specialized explosion-proof design. The fan used in the ventilation device is not an ordinary fan; its motor, blades, and casing all adopt a non-sparking design, ensuring that even if an internal malfunction occurs during operation, no mechanical sparks or high-temperature surfaces sufficient to ignite an explosive mixture will be generated. The key control component of the atomizing dust suppression device—the solenoid valve—is an intrinsically safe product. This solenoid valve and its associated circuit are specially designed so that even in the event of a short circuit or open circuit, the energy released is strictly limited to a safe range, insufficient to ignite specific levels of flammable gases or dust. This design is the fundamental guarantee for the reliable operation of the system in hazardous areas. It reduces the potential ignition risk of the linkage execution module itself to zero. The use of non-sparking fans and intrinsically safe solenoid valves ensures that even when a high concentration of hazardous materials is detected and an emergency response is initiated, these operating safety devices will never become a new ignition source, thus avoiding secondary accidents caused by "disaster relief efforts." This reflects the forward-looking and comprehensive nature of the system design, ensuring that all aspects of the entire safety system, from perception to execution, meet explosion-proof requirements and achieve the standard of intrinsic safety.

[0024] In this embodiment, the central control module connects to the enterprise intranet or the internet via an industrial router, establishing an encrypted communication connection with the cloud server. Simultaneously, it supports connection via VPN to remote monitoring terminals (such as computers or mobile apps) of the company headquarters or safety management personnel. All monitoring data, alarm events (time, location, type, concentration value), and linkage action records (when, where, and what operation was performed) are uploaded to the cloud server in real time and simultaneously pushed to remote terminals. Authorized personnel can view a panoramic view of the workshop safety situation in real time, access historical data reports, and, in special circumstances (such as when the automatic system fails), send remote manual control commands to directly start or stop ventilation, spraying, or power-off devices on-site. The remote monitoring and data upload functions realize the digitalization, visualization, and mobility of safety management. It breaks the geographical limitations of safety monitoring, enabling managers to grasp the on-site safety status anytime, anywhere, achieving an upgrade from "on-site duty" to "remote supervision." Complete event logs provide tamper-proof data for accident tracing, responsibility determination, and safety auditing. The remote manual control function is the last line of defense in extreme situations, increasing system redundancy and reliability. This constitutes a new three-dimensional safety management model that combines "automatic on-site handling with remote supervision and intervention".

[0025] In the deployment plan of this embodiment, a clear definition and typical examples of "risk points" are provided. The monitoring module and the linkage execution module are specifically and densely arranged in several known highest-risk process links. For example, at the inlet and outlet areas of the crusher, the instantaneous high-concentration dust clouds generated by material impact and crushing are mainly monitored; in the working area of the plastic baler, the VOCs release and plastic dust possibly caused by friction heating are mainly monitored; in the material temporary storage warehouse containing waste chemical containers or waste textiles, the accumulation of VOCs is mainly monitored. The system's point layout strategy is not evenly distributed but is based on the results of process hazard analysis (PHA) to achieve key monitoring of the most dangerous sources. Defining typical risk points concretizes the protection scope of the present invention and reflects the scientific nature of its deployment. This targeted point layout strategy ensures that limited monitoring and protection resources are invested in the links with the highest risks, maximizing the benefits of safety investment. It directly targets the "pain points" areas where accidents are most likely to occur in the renewable resource treatment center, such as the crushing, packing, and storage links, making the system's protection measures targeted, greatly enhancing the accuracy and effectiveness of overall safety protection, and providing a clear example and guidance for the system deployment of similar sites.

[0026] In this embodiment, a high-level early warning analysis unit is integrated into the software of the central control module. This unit is built with machine learning algorithms and continuously analyzes the time series of concentration data at each monitoring point. It not only focuses on the current instantaneous value but also analyzes the rising rate and fluctuation trend of the concentration and compares it with the data patterns under the same working conditions in history. For example, the system can identify dangerous patterns such as "the concentration rises exponentially in a short time" or abnormal patterns such as "the concentration peak at a fixed time every day continues to rise slowly". Based on these analyses, even before the concentration reaches the preset fixed threshold, the system can predict the risk trend several minutes or even longer in advance and generate a yellow early warning signal on the monitoring interface, indicating that "the point concentration shows a rapid upward trend and is expected to reach the warning threshold within 5 minutes", thus winning valuable time for preventive manual intervention. The early warning analysis unit elevates the system's safety from "real-time response" to a higher level of "advance prediction". It changes the passive situation where traditional alarm systems can only respond to established risks and realizes early identification and warning of risks through intelligent algorithms. This enables safety management personnel to shift from "post-event emergency" to "pre-event prevention" and take measures such as adjusting the process and strengthening ventilation before potential risks reach a dangerous level, thereby possibly completely avoiding linkage alarms and even accidents. This represents a key evolution of the safety management system from automation to intelligence, greatly enhancing the initiative and forward-looking nature of safety management.

[0027] The working principle and operation process of the system described in this invention is a complete closed loop from data acquisition and intelligent analysis to automatic execution. After the system is powered on and initialized, each module enters a ready state. Monitoring modules distributed at risk points such as the crusher inlet, discharge area, packaging station, and material storage warehouse begin to work continuously. Their built-in dust concentration sensors and VOCs gas sensors collect ambient air samples at a set frequency (e.g., once per second) and transmit the converted concentration electrical signals to the central control module in real time. At the same time, the self-cleaning unit integrated into the monitoring module starts according to a preset cycle. An inert clean gas is sprayed out by an air curtain generator to form a protective air curtain on the surface of the sensor probe, effectively blowing away and blocking the adhesion of dust and oil, thereby ensuring the long-term reliability and accuracy of the monitoring data at the source. Throughout the entire process, the system completes all-weather, all-round automatic perception of hazardous factors.

[0028] The central control module, acting as the system's brain, processes the collected real-time data stream at high speed. Its early warning analysis unit first performs time-series analysis on the data stream, comparing historical data models with real-time trends and using algorithms to predict future concentration trends. It generates forward-looking early warning information before the concentration value reaches a fixed threshold. For current data, the control core invokes an environmental compensation algorithm, combining it with temperature and humidity data collected from the same location to calibrate the original concentration reading, eliminating environmental interference and obtaining a more accurate "standard state concentration value." This corrected value is then sent to a multi-level logic judgment unit, comparing it step-by-step with preset first early warning thresholds, second action thresholds, and third danger thresholds. The system continuously calculates and updates a dynamic risk level label for each independent monitoring point, achieving intelligent mapping from raw data to risk status.

[0029] Once the risk level at a certain point is determined to be elevated, the system immediately triggers the preset response logic. If the concentration reaches the first warning threshold, the central control module generates a first-level linkage command, which is precisely sent to the linkage execution module at the corresponding point, driving the audible and visual alarm to activate and issue an audible and visual warning to alert on-site personnel. If the concentration continues to climb to the second action threshold, the system, while maintaining the alarm, generates a second-level linkage command, automatically activating the sparkless ventilation fan and the intrinsically safe solenoid valve-controlled atomizing dust suppression device at that point. By enhancing ventilation and spraying dust suppression, the system actively intervenes in the environment in an attempt to reduce the concentration of hazardous materials. This is the system's first automatic line of defense.

[0030] When the concentration spikes to the third danger threshold, indicating an imminent risk of combustion and explosion, the system will immediately generate a highest-priority mandatory command. This command will instantly cut off the main power supply to all production equipment (such as crushers and conveyors) within the risk area via the equipment power controller, eliminating the ignition conditions at their source and providing ultimate safety assurance. This tiered response mechanism ensures a strict match between measures and risks, preventing overreaction.

[0031] After the linked action is executed, the system enters the post-alarm monitoring and recovery stage. The central control module continuously monitors the concentration changes at relevant points until it drops below the safety threshold and remains stable for a preset duration (such as 5 minutes), then it is determined that the risk has been completely eliminated. Subsequently, the system automatically sends a解除指令 (it should be "release instruction" in English), gradually stops the ventilation and dust suppression equipment, or restores the power supply of the production equipment, enabling the area to safely and orderly return to normal production, forming a complete disposal-recovery closed loop.

[0032] During the entire operation process, all data streams, event logs (including alarms, linked actions, recovery records) are synchronously stored and analyzed on the cloud server in real time and presented on the remote monitoring terminal. Managers can remotely grasp the overall security situation and perform manual intervention when necessary. At the same time, all electrical equipment in the linked execution module meets the explosion-proof standards, ensuring its absolute safety during the task execution and not becoming a secondary risk source. The entire system thus achieves full-link automation and intelligence from perception, decision-making, execution, recovery to supervision, upgrading the static protection to a dynamic proactive safety system.
