Description

Technical Field

[0001] The invention belongs to the field of new pollutant migration simulation, in particular to a new pollutant migration and transformation multi-media simulation device. Background Art

[0002] New pollutants refer to a type of pollutants that have gradually been identified in the environment in recent years, but pose potential risks to ecosystems and human health and have not yet been included in the routine environmental monitoring and control system.

[0003] The migration pathways of emerging pollutants (such as PFAS and microplastics) within environmental media (water, soil, and air) directly impact their exposure. For example, PFAS can migrate through groundwater to drinking water sources, or microplastics can enter farmland through atmospheric deposition, ultimately accumulating through the food chain and posing a threat to human health.

[0004] Studying the migration process can quantify the cumulative effects of pollutants in organisms and provide a basis for establishing safety thresholds.

[0005] Traditional pollutant migration devices are mostly designed for a single medium and cannot simultaneously simulate the migration and transformation process of pollutants in solid-liquid-gas multiphase media, resulting in large differences between experimental results and the real environment.

[0017] Preferably, one side of the simulation box shell is further provided with a plurality of heat conduction channels;

[0018] After penetrating the conductive plate, several groups of heat conduction channels extend into the first migration reaction chamber, the second migration reaction chamber, and the third migration reaction chamber respectively.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figure 1 As shown:

[0040] Example 1: The present invention provides a new pollutant migration and transformation multi-media simulation device, comprising a migration reaction chamber mechanism 1, a conductive plate 2, an environmental simulation box mechanism 3, a new pollutant injection port 4 and a collection channel 5;

[0041] The migration reaction chamber mechanism 1 includes a migration reaction chamber 11, a migration reaction chamber 2 12, and a migration reaction chamber 3 13, which are equidistantly arranged in parallel. A solenoid valve 14 is provided between the migration reaction chamber 11 and the migration reaction chamber 2 12, and a solenoid valve 2 15 is provided between the migration reaction chamber 2 12 and the migration reaction chamber 3 13.

[0042] One side of the conductive plate 2 is tightly sealed against one surface of the migration reaction chamber 1 11 , the migration reaction chamber 2 12 and the migration reaction chamber 3 13 , and the other side of the conductive plate 2 is fixedly connected to the environmental simulation box mechanism 3 ;

[0043] The conducting plate 2 is made of heat-conducting and light-transmitting material;

[0044] The solenoid valve 14 and the solenoid valve 2 15 are arranged diagonally;

[0045] The new pollutant injection port 4 is set at a diagonal position on the migration reaction chamber 11 away from the solenoid valve 14, and the collection channel 5 is set at a diagonal position on the migration reaction chamber 3 13 away from the solenoid valve 2 15.

[0046] As can be seen from the above, during operation, new pollutants are injected into the migration reaction chamber 1 11 through the new pollutant injection port 4. Under the coordinated control of the solenoid valve 1 14 and the solenoid valve 2 15, the pollutants flow through the migration reaction chamber 2 12 and the migration reaction chamber 3 13 in sequence, and are finally discharged and collected by the collection channel 5.

[0047] By controlling the working time of the electromagnetic valve 14 and the electromagnetic valve 2 15, the residence time of the new pollutants in each reaction chamber can be indirectly controlled. Finally, the final pollutants can be collected through the collection channel 5 and further analyzed.

[0048] The conductive plate 2 transmits the environmental conditions such as light and temperature applied by the environmental simulation box mechanism 3 to each migration reaction chamber through its heat conduction and light transmission properties, driving the pollutants to react under different conditions in each migration reaction chamber;

[0049] The diagonal arrangement of the solenoid valve 14 and the solenoid valve 2 15 forms a staggered flow channel, which prolongs the diffusion path of the pollutants between the cavities.

[0050] The diagonal arrangement of the new pollutant injection port 4 and the collection channel 5 can also promote the directional flow of pollutants through spatial potential difference, thereby simulating the dynamic process of pollutant migration in the natural environment.

[0051] like Figure 2 As shown:

[0052] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the environmental simulation box mechanism 3 includes a simulation box housing 31, and a set of partition plates 32 are fixedly installed inside the simulation box housing 31;

[0053] The simulation box housing 31 is sealed and fixed to one side of the conductive plate 2;

[0054] A set of partition plates 32 divides the simulation box housing 31 into three equal chambers, each corresponding to the migration reaction chamber 1 11, the migration reaction chamber 2 12 and the migration reaction chamber 3 13. The partition plates 32 are made of heat-insulating and light-blocking materials.

[0055] Each chamber separated by the partition plate 32 is provided with a lighting system 33 and a heating system 34 .

[0056] Specifically, one side of the simulation box housing 31 is further provided with a plurality of groups of heat conduction channels 35;

[0057] A plurality of heat conduction channels 35 penetrate the conductive plate 2 and extend into the first migration reaction chamber 11 , the second migration reaction chamber 12 and the third migration reaction chamber 13 respectively.

[0058] As can be seen from the above, during operation, new pollutants enter the migration reaction chamber 11 through the new pollutant injection port 4, flow to the migration reaction chamber 2 12 through the solenoid valve 14, and then enter the migration reaction chamber 3 13 through the solenoid valve 2 15, and are finally discharged and collected by the collection channel 5;

[0059] During this process, the conductive plate 2 transmits the light and heat conditions generated by the illumination system 33 and the heating system 34 of the three independent chambers separated by the partition plate 32 in the environmental simulation box mechanism 3 to the corresponding migration reaction chamber;

[0060] Preferably, the light and heat conditions can be guided to the migration reaction chamber 1 11, the migration reaction chamber 2 12 and the migration reaction chamber 3 13 through the heat conduction channel 35, and the heat conduction channel 35 is made of a heat-conducting transparent material;

[0061] The heat-insulating and light-blocking properties of the partition plate 32 ensure that the environments of each chamber do not interfere with each other. The sealed connection between the simulation box shell 31 and the conductive plate 2 allows different media to act on the migration reaction chamber under different light intensities and temperature gradients, driving the directional migration and multiphase transformation of pollutants in differentiated environments.

[0062] like Figure 3 As shown:

[0063] Example 3: This example is basically the same as Example 2, except that a sampling port 111 is further provided on the outer side of the migration reaction chamber 11;

[0064] The sampling port 111 is sealed under normal conditions;

[0065] Specifically, a second sampling port 121 is further provided on the outside of the second migration reaction chamber 12;

[0066] The sampling port 2 121 is sealed under normal conditions;

[0067] Specifically, a sampling port 3 131 is further provided on the outside of the migration reaction chamber 3 13;

[0068] Sampling port 3 131 is sealed under normal conditions.

[0069] As can be seen from the above, during operation, sampling port 1 111, sampling port 2 121 and sampling port 3 131 are kept sealed under normal circumstances. When sampling is required, the pollutant samples in the migration reaction chamber can be extracted in real time by opening the corresponding sampling ports to analyze the migration and transformation status of pollutants in different media such as soil, water and air. The sealing design ensures that there is no leakage interference during system operation and maintains the stability of the experimental environment.

[0070] Example 4: This example is basically the same as Example 2, except that both solenoid valve 14 and solenoid valve 2 15 are adjustable flow solenoid valves, and are both electrically connected to the central controller, which controls the opening and closing and opening degree of the valves through a preset program.

[0071] Specifically, the lighting system 33 includes a multi-band LED light source and an ultraviolet lamp group, with a wavelength coverage range of 200-800nm, and the light source intensity can be adjusted in stages by an external controller.

[0072] Specifically, the heating system 34 has a built-in PID temperature control module with a temperature adjustment range of -10°C to 150°C and an accuracy of ±0.5°C.

[0073] Specifically, the migration reaction chamber 1 11 , the migration reaction chamber 2 12 and the migration reaction chamber 3 13 are filled with soil, water and air media respectively, and the side walls of the chambers are provided with medium replacement ports, which are sealed by flanges.

[0074] As can be seen from the above, during operation, the illumination system 33 provides a graded and adjustable composite light field through a multi-band LED light source and a UV lamp group, and the heating system 34 uses a PID temperature control module to accurately control the temperature. The two synchronize the differentiated light and heat conditions to each reaction chamber through the conductive plate 2;

[0075] The medium replacement port 16 on the side wall of the migration reaction chamber is sealed with a flange to achieve rapid replacement of soil, water and air media. Combined with the flow coordinated control of the solenoid valve, it accurately simulates the dynamic migration, phase transformation and environmental response process of pollutants in solid-liquid-gas multiphase media.

[0076] Example 5: This example is basically the same as Example 2, except that it also includes a data acquisition system. The data acquisition system includes a pH sensor, a temperature sensor and an optical concentration probe embedded in the migration reaction chamber. The data is transmitted to an external terminal in real time through a wireless module.

[0077] As can be seen from the above, during operation, the data acquisition system monitors the pH value, temperature and concentration dynamic changes of pollutants in soil, water and air media in real time through the pH sensors, temperature sensors and optical concentration probes embedded in each migration reaction chamber, and transmits the data synchronously to the external terminal through the wireless module;

[0078] The illumination system 33 and heating system 34 of the environmental simulation chamber mechanism 3 transmit customized photothermal conditions to the migration reaction chamber through the conduction plate 2, and the real-time feedback of the data acquisition system can be linked with the central controller. When an abnormal pollutant concentration is detected, the solenoid valve emergency shutdown program is automatically triggered to ensure the controllability and safety of the experimental process, while providing accurate dynamic data support for the study of multi-media migration and transformation mechanisms.
