[0002] In the field of toxic and hazardous chemical management, the management typically focuses on chemical companies to reduce environmental pollution and human harm caused by these chemicals. Currently, traditional toxic and hazardous chemical management systems generally only possess basic data statistical analysis functions, leading to the following technical shortcomings: delayed monitoring of new pollutants, making it difficult to prevent irreversible environmental risks from long-term accumulation; failure to establish a chemical-based hierarchical classification mechanism, resulting in the mixed management of high-risk and low-risk substances and poor management effectiveness; lack of scientific enterprise classification standards, leading to unclear regulatory targets and fragmented regulatory resources; and insufficient targeting and management efficiency due to the lack of risk level correlation in management requirement push notifications and outdated on-site monitoring methods. Therefore, we propose a toxic and hazardous chemical management information classification and push device and method. Summary of the Invention

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 Please see the appendix Figure 1 A device for classifying and pushing information on the management of toxic and hazardous chemical substances, comprising: an information collection module, an environmental risk classification module, a chemical substance enterprise classification module, and an information push module; The information collection module is used to acquire information data on toxic and hazardous chemicals from multiple chemical companies. In this embodiment, the information data on toxic and hazardous chemicals includes, but is not limited to, the identification information of the chemical substances, their inherent hazard properties, and flow data covering their use, emissions, and end-of-pipe treatment efficiency. The acquisition methods include, for example, enterprises logging into the designated regulatory information platform to fill in and upload data, regulatory personnel collecting and entering data through mobile terminals during on-site verification, and government regulatory databases, etc., which will not be described in detail here. The environmental risk classification module compares information on toxic and hazardous chemical substances with a database of new pollutants, such as the officially published "List of Key Controlled New Pollutants." When a chemical substance is identified as a new pollutant, it is classified as a Level 1 environmental risk. For non-new pollutants, they are classified into Level 1, Level 2, or Level 3 environmental risk based on the information on toxic and hazardous chemical substances (such as identification information and inherent hazard attributes). This module significantly improves the accuracy and efficiency of managing new pollutants (a specific category of chemical substances with special hazards requiring priority control). Optionally, in this embodiment, Level 1 environmental risk refers to substances with severe and irreversible hazardous characteristics, typically including those listed in the traditional "List of Priority Controlled Chemicals" or those conforming to GHS (Globally Harmonized Classification and Labelling System). The highest category of hazards: Level 1: Substances with clear hazards but relatively low toxicity, persistence or accumulation; Level 2: Hazardous chemicals that are widely used in industry and require regulated management; Level 3: Substances with low hazard, which are easily degraded in the environment and do not easily accumulate in organisms. The chemical substance enterprise classification module is used to classify chemical substance enterprises according to the highest environmental risk level of the toxic and hazardous chemical substances they are involved in. Among them, chemical substance enterprises involving the highest environmental risk level are classified as key regulatory units, and other chemical substance enterprises are classified as general regulatory units. This chemical substance enterprise classification module ensures that all enterprises involving new pollutants and other highest risk substances can be accurately included in the key regulatory scope. At the same time, by implementing appropriate supervision of general regulatory units, the allocation of regulatory resources is optimized, and the comprehensiveness and efficiency of environmental supervision are significantly improved. The information push module is used to push environmental management requirements of the same environmental risk level and category as the chemical substances used by key regulatory units and general regulatory units. Optionally, in this embodiment, the environmental management requirements include mandatory control contents such as treatment technical specifications, emission concentration limits, total usage control, storage safety management and transfer tracking regulations. It is also used to send signals to the monitoring machines deployed in each key regulatory unit to control the monitoring machines to monitor the key regulatory units and carry out risk warning work. The above method effectively solves the pain points of insufficient targeting and delayed implementation feedback in traditional environmental management requirement push, realizes accurate delivery and mandatory reminder of regulatory requirements, significantly improves the execution efficiency and regulatory effectiveness of environmental management, and enables further control of key regulatory units through the monitoring machines deployed in each key regulatory unit.

[0020] Preferably, the push device in this embodiment further includes a data storage module and a data statistical analysis module; The data storage module is used to store information on toxic and hazardous chemicals, environmental risk level information, and push information sent by the information push module. The data statistical analysis module is used to perform statistical analysis on the classification data of multiple chemical companies and the graded data of toxic and hazardous chemicals produced by chemical companies. The data storage module and data statistical analysis module mentioned above are conventional modules in this field and will not be described in detail here.

[0021] A method for classifying and pushing information on the management of toxic and hazardous chemicals, utilizing the aforementioned push device, includes the following steps: S1: Obtain information data on toxic and hazardous chemical substances from multiple chemical companies through the information collection module; S2: The environmental risk classification module compares the information data of toxic and hazardous chemical substances with the list of new pollutants in the database. When a chemical substance is identified as a new pollutant, it is classified as a special environmental risk level. For non-new pollutants, they are classified as first-level, second-level or third-level environmental risk levels according to the information data of toxic and hazardous chemical substances. S3: Based on the highest environmental risk level of the toxic and hazardous chemicals involved, chemical companies are classified through the chemical company enterprise classification module. Among them, chemical companies involving the highest environmental risk level are classified as key regulatory units, and the rest of the chemical companies are classified as general regulatory units. S4: The information push module pushes environmental management requirements of the same environmental risk level and category as the chemical substances used by key regulatory units and general regulatory units. It is also used to send signals to the regulatory machines deployed in each key regulatory unit to control the regulatory machines to supervise the key regulatory units and carry out risk warning work.

[0022] Example 2 Please see the appendix Figure 2-4 Based on Embodiment 1, the monitoring machine of this embodiment includes a housing 1, a risk warning unit disposed on the housing 1, and a processing verification unit disposed inside the housing 1. A door 2 is provided on one side of the housing 1. Optionally, the door 2 and the housing 1 are connected by a door lock and are managed and maintained by the environmental regulatory department. The risk warning unit and the processing verification unit can be remotely connected to the environmental regulatory department and the environmental regulatory department can remotely control and supervise key regulatory units. The risk warning unit includes a display screen 3 installed on the shell door 2 and an alarm 4 and a speaker 5 installed on the shell 1. The display screen 3, alarm 4 and speaker 5 are all conventional electrical components in the field. The display screen 3 dynamically updates and pushes information, compliance requirements and monitoring data, etc. The alarm 4 and speaker 5 can be controlled by the environmental regulatory department to provide risk warnings to ensure that key regulatory units receive the information. The processing verification unit includes a detection device 6 housed within the casing 1, a water inlet pipe 7 and an air inlet located at the input end of the detection device 6. The water inlet pipe 7 is connected to the discharge pipeline of the chemical enterprise after wastewater treatment, and the air inlet is connected to the discharge pipeline of the chemical enterprise after exhaust gas treatment. The output end of the detection device 6 is also connected to a drainage main pipe 14 and an exhaust main pipe 15. Solenoid valves are installed in the water inlet pipe 7, the air inlet, the drainage main pipe 14, and the exhaust main pipe 15. Optionally, pumps can be installed on the water inlet pipe 7 and the air inlet in this embodiment. The environmental regulatory department controls the processing verification unit to periodically draw wastewater or exhaust gas discharged from the discharge pipeline into the detection device 6 for testing indicators such as the concentration of new pollutants. After verification, the sample is discharged back to the enterprise's total emission system through the drainage main pipe 14 and the exhaust main pipe 15. If the verification fails, a push notification and a warning signal are sent to the enterprise through the risk warning unit.

[0023] Preferably, the detection device 6 in this embodiment includes a housing 61, a quartz detection tank 62 disposed inside the housing 61 for communication with the water inlet connection pipe 7, the air inlet, the drain pipe 14 and the exhaust pipe 15, and an emitter 63 and a detector 64 symmetrically disposed on the two inner walls of the housing 61 and corresponding to each other. When wastewater or exhaust gas flows into the quartz detection tank 62, the emitter 63 emits ultraviolet light of a specific wavelength that penetrates the wastewater or exhaust gas, and the detector 64 analyzes the concentration of new pollutants in real time by receiving the fluorescence signal absorbed or excited by the wastewater or exhaust gas. This method is widely used in the field and will not be described in detail here.

[0024] Preferably, the air inlet of this embodiment includes an adsorption tank 9 disposed within the housing 1, an air inlet pipe 8 connected at one end to the adsorption tank 9 and at the other end to the detection device 6, an air inlet connecting pipe 12 connected at one end to the adsorption tank 9 and at the other end to the discharge pipe after the chemical waste gas treatment of the chemical enterprise, and a material storage container 21 disposed within the adsorption tank 9. In this embodiment, the material storage container 21 is cylindrical in the middle and trapezoidal in the vertical cross-section of the upper and lower ends to facilitate feeding and discharging. The top of the material storage container 21 is connected to a directional storage device via a pipe (a pipe with a solenoid valve). The material container 21 contains a feeding tank 10 for adding adsorbent particles (such as carbon molecular sieves). The bottom of the material container 21 is connected to a waste tank 11 through a pipeline (a pipeline with a solenoid valve). Both the waste tank 11 and the feeding tank 10 are located inside the shell 1. The material container 21 is equipped with a vibrator and a heating element (such as an electric heating element). Ventilation holes are opened on the outer walls of the upper and lower ends of the material container 21. In this embodiment, the inner diameter of the ventilation hole is smaller than the particle size of the adsorbent particles. The material container 21 is also connected to a device that supplies carrier gas (such as nitrogen) from the outside through a gas supply connection pipe 13. Before entering the detection equipment 6, the exhaust gas first enters the adsorption tank 9, where the target pollutants in the exhaust gas are adsorbed by the adsorption particles (non-target pollutants are discharged through the inlet pipe 8, the detection equipment 6, and the exhaust pipe 15, etc.). Then, the target pollutants are desorbed by the adsorption particles by turning on the heating element. Then, the carrier gas is supplied to the material container 21 through the external carrier gas supply device and the gas supply connection pipe 13, so that the carrier gas carries the target pollutants into the detection equipment 6 for detection. This method improves the detection effect of the detection equipment 6 on the exhaust gas. During long-term use, the adsorbent particles in the material container 21 can be discharged to the waste tank 11 through the pipeline by the vibrator. After discharge, new adsorbent particles can be added to the material container 21 through the feeding tank 10.

[0025] Example 3 Please see the appendix Figure 3-5Based on Embodiment 2, this embodiment further includes a sample retention section within the housing 1. The sample retention section includes a rotating device 18 (such as a stepper motor and reducer) within the housing 1, and a rotating frame 16 (circular in cross-section) mounted on the rotating device 18. Several sets of sample bottles 19 are movably inserted into the inner and outer sides of the rotating frame 16 in a circular array. Specifically, the rotating frame 16 has a circular opening for inserting the sample bottles 19, and one sample bottle 19 on each side corresponds to the tail end of the drain pipe 14 and the exhaust pipe 15 (the tail ends of the drain pipe 14 and the exhaust pipe 15 are the ends furthest from the detection device 6). This method ensures that each time the rotating device 18 controls the rotating frame 16 to rotate a preset angle, one sample bottle 19 on each side corresponds to the tail end of the drain pipe 14 and the exhaust pipe 15. Corresponding to the end, the bottom of the rotating frame 16 is fitted with a fixed frame 17 connected to the inner wall of the housing 1. The top of the fixed frame 17 is fitted with the bottom of the sample bottle 19 to prevent the sample bottle 19 from falling downward and detaching from the rotating frame 16. The fixed frame 17 has openings for the sample bottle 19 to pass through at the positions corresponding to the drain pipe 14 and the exhaust pipe 15. A movable sealing plate 22 for sealing the opening is inserted on one side of the fixed frame 17. The top of the movable sealing plate 22 is flush with the top of the fixed frame 17. A movable opening 23 for communicating with the opening is opened through the movable sealing plate 22. The movable sealing plate 22 is driven to move horizontally by a telescopic device 20 (such as an electric telescopic rod) located on the outer wall of the housing 1. A sample storage shell 34 is provided inside the housing 1 at the position corresponding to the opening. The top of the sample storage shell 34 is hollow, and its inner wall can be lined with a rubber pad to prevent the sample bottle 19 from being damaged by collision. Preferably, the sample bottle 19 in this embodiment has an injection port at the top. The inner wall of the injection port in this embodiment is fitted with a rubber sealing ring to ensure a sealed contact with the connecting member. The top wall of the sample bottle 19 is fitted with a sealing plate 25 to close the injection port, and the sealing plate 25 is connected to the inner wall of the sample bottle 19 by an elastic member 24 (such as a spring). The diameter of the sealing plate 25 is larger than the diameter of the injection port and smaller than the inner diameter of the sample bottle 19. When the sealing plate 25 is disengaged from the injection port, wastewater and waste gas can enter the sample bottle 19 from the position between the sealing plate 25 and the injection port. The tail ends of the drain pipe 14 and the exhaust pipe 15 are provided with connecting members for inserting into the injection port and communicating with the sample bottle 19. The connecting members in the drain pipe 14 and the exhaust pipe 15 have the same structure. A support frame 26 connected to the inner wall of the housing 1 is provided at a distance below the drain pipe 14 and the exhaust pipe 15. A clearance opening for the connecting member is provided on the support frame 26 at the position corresponding to the position of the connecting member. An electromagnetic block 27 for driving the connecting member to communicate with the sample bottle 19 is also provided on the support frame 26 at the position corresponding to the position of the connecting member.

[0026] Because the connecting parts in the main water pipe and the main exhaust pipe 15 have the same structure, the following description focuses on the connecting part in the main drain pipe 14. The connecting part in the main exhaust pipe 15 will not be described in detail. Preferably, the connecting part in the main drain pipe 14 of this embodiment includes: a fixed seat 28 fixedly disposed in the main drain pipe 14; a closed column 29 inserted at the bottom of the fixed seat 28 with a diameter smaller than the inner diameter of the main drain pipe 14; and a connecting branch pipe with one end penetrating the main drain pipe 14 and contacting the outer wall of the closed column 29. In this embodiment, the connecting branch pipe can be connected to the enterprise's main discharge system. A sealing ring is embedded at the end of the connecting branch pipe that contacts the outer wall of the closed column 29 to ensure a sealed contact between the two. A channel 31 is opened in the closed column 29, with one end connected to the connecting branch pipe and the other end penetrating the fixed seat 28. The channel 31 is L-shaped. A connecting pipe 30 for inserting an injection port is connected to the bottom of the closed column 29. The diameter of the connecting pipe 30 is adapted to the inner diameter of the injection port. The connecting pipe 30 is movably inserted into the tail end of the main exhaust pipe 15. A connection is provided between the connecting pipe 30 and the main exhaust pipe 15. The second elastic element 33 in this embodiment is a spring with one end connected to the outer wall of the connecting pipe 30 and the other end connected to the exhaust pipe 15. A magnetic ring 32 corresponding to the electromagnetic block 27 is sleeved on the connecting pipe 30. The outer wall of the end of the connecting pipe 30 used for insertion into the injection port has several sets of discharge ports. When the electromagnetic block 27 is energized, it attracts the magnetic ring 32, thereby causing the connecting pipe 30 to move downward to a preset position. The connecting pipe 30 is inserted downward into the injection port and pushes the sealing plate 25 to squeeze the first elastic element 24. At this time, the discharge port... The sample bottle 19 is located between the injection port and the sealing plate 25. When the connecting pipe 30 is downward, it also drives the sealing column 29 downward to the preset position. At this time, one end of the channel 31 in the sealing column 29 is offset from the sealing column 29, and the connecting branch pipe is then sealed by the sealing column 29. This allows the wastewater in the main drainage pipe 14 to enter the connecting pipe 30 through the channel 31, and then enter the sample bottle 19 through the outlet. After a suitable amount of wastewater enters the sample bottle 19, the electromagnetic block 27 is closed, the connecting pipe 30 is reset, and the sealing plate 25 is reset at the same time. Subsequently, by controlling the telescopic device 20, the movable sealing plate 22 is moved so that the movable opening 23 on the movable sealing plate 22 corresponds to the sample bottle 19 containing wastewater. At this time, the sample bottle 19 containing wastewater falls down into the sample storage shell 34 through the movable opening 23 and the outlet. Environmental regulatory personnel can periodically take the sample as evidence to better supervise key regulatory units.

[0027] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
