Compared with GC-MS technology, this study simplified the analysis process and achieved a preliminary analysis of asphalt fume components.

When the simulation scene is activated, the present invention uses gas sensor I, gas sensor II, gas sensor III, and gas sensor IV to monitor the four main components in the bitumen fume in real time. The dynamic detection system collects bitumen fume samples based on the gas flow theory, and generates a dynamic image of the change of the concentration of the four main gases over time through the data processing terminal. The simulation process is further analyzed based on the proposed comprehensive environmental evaluation method to reveal the emission characteristics of bitumen fume in different scenarios. According to relevant standards, the present invention selects four main components in bitumen fume for detection. Compared with gas chromatography-mass spectrometry (GC-MS) and traditional gas detection devices, the systematic structure of the device has the ability to monitor the key components in bitumen fume in real time, and has significant advantages in time resolution. This function enables a detailed analysis of the time-varying emission pattern of bitumen fume.

After the environmental simulation module is started, the gas concentration in the environmental chamber reaches the detection threshold, and gas sensor I (VOCs), gas sensor II (PM 2.5 ), gas sensor III (SO2), and gas sensor IV (NO) detect four main smoke components, and use a wireless signal transmitter (or data transmission line) to transmit the detection data.

[0048] Embodiment 2

[0049] This embodiment also provides an environmental comprehensive evaluation method based on the asphalt fume collection and detection device. The environmental comprehensive evaluation method includes the following steps: obtaining simulated environmental data based on the asphalt modification process simulated by the environmental simulation module; using the asphalt fume collection and real-time detection module to detect the fume components based on the simulated environmental data to obtain detection data; processing the detection data based on the data processing module to obtain processed data; based on the processed data, calculating the smoke suppression rate and weight factor of the asphalt fume through the constructed evaluation matrix and weight factor; based on the smoke suppression rate and weight factor, calculating the comprehensive environmental evaluation index through weighted summation; based on the comprehensive environmental evaluation index, dividing the comprehensive environmental index of the asphalt fume into five energy-saving and emission reduction levels to obtain a comprehensive environmental evaluation result.

[0064] When 320<CEAI≤420, the comprehensive environmental index is the fourth energy conservation and emission reduction level;

[0065] When 420<CEAI<580, the comprehensive environmental index is the fifth energy conservation and emission reduction level.

[0066] Embodiment 3

[0067] This embodiment provides an asphalt fume collection and detection device and a comprehensive environmental evaluation method thereof. This embodiment sets the following Example 1:

[0068] (1) Environmental simulation module: To simulate the asphalt modification process, 100 g of asphalt A (base asphalt) was placed in a temperature regulator at 165 °C, 5-10 g of waste rubber powder was added and stirred at 400 r / min for 5 min, then the speed was increased to 1000 r / min and stirred for 20 min; then the same modified asphalt was used to simulate the mixing process of dry-mixed asphalt and aggregate, the mixing process of wet-mixed asphalt and aggregate, and the heating process of asphalt A.

[0069] (2) Asphalt fume collection and real-time detection module: After the environmental chamber displays that the gas concentration has reached the threshold, the gas sensor I (VOCs) and gas sensor II (PM 2.5 ), gas sensor III (SO2), and gas sensor IV (NO) detect four main smoke components, and use a wireless signal transmitter (or data transmission line) to transmit the detection data.

[0070] (3) Data processing module: The computer is used to collect the concentrations of the four main components of asphalt fume and the relevant data on the corresponding temperatures of the corresponding concentrations, and further conduct a comprehensive environmental evaluation of the asphalt fume.

[0071] (4) Asphalt fume treatment module: After the asphalt fume collection and real-time detection module is finished working, turn on the air pump. The air pump uses the internal power motor to collect the asphalt waste gas through the air duct into the waste gas collector, and start the simple spraying facility inside the waste gas collector to easily treat the asphalt fume.

[0072] Comparative Example 1: Only the asphalt heating and modification process was simulated, and the smoke suppression material A, energy-saving material A and smoke suppression and energy-saving material A (a composite of smoke suppression material A and energy-saving material A) were added and then the heating and modification processes were carried out respectively.

[0073] Comparative Example 2: Only the asphalt heating and modification process was simulated, and the heating and modification processes were respectively carried out after smoke suppression material B, energy-saving material B and smoke suppression and energy-saving material B were added.

[0074] Comparative Example 3: Only the asphalt heating and modification process was simulated, and the heating and modification processes were respectively carried out after smoke suppression material C, energy-saving material C and smoke suppression and energy-saving material C were added.

[0075] Test: In the environmental chamber, Example 1 simulates the heating, modification, dry mixing and wet mixing processes of 100gA asphalt at 165°C. Comparative Examples 1 to 3 simulate the heating and modification processes of asphalt under three conditions. After the process of flue gas generation, collection and detection, the data terminal processing results are collected, and the final results are judged according to the table of influence importance and effect size. The pollutant concentrations in the asphalt flue gas under different simulated environments corresponding to Example 1 are shown in Table 4, the comprehensive environmental levels are shown in Table 5, and the heating and modification test results after smoke suppression and energy-saving treatment corresponding to Comparative Examples 1, 2 and 3 are shown in Table 6.

[0076] Table 4

[0077]

[0078] As shown in Table 4, the four different simulated environments have the same pattern, with VOCs concentration increasing fastest, followed by PM 2.5, SO2 and NO concentrations increased relatively slowly, but also showed a trend of continuous growth; after asphalt modification (rubber powder modification), PM 2.5 The concentrations of VOCs and carbon black in the rubber powder and undecomposed rubber particles formed particulate matter that contributed to PM. 2.5 The concentration of VOCs increases when the rubber in the rubber powder is heated and the rubber in the rubber powder undergoes thermal decomposition, which intensifies the release of VOCs. The concentrations of SO2 and NO also increase to a certain extent, but at a slower rate. This may be because the sulfur in the asphalt exists in the form of easily decomposable forms such as thiophene, so it is released faster, while the sulfur and nitrogen in the rubber powder are wrapped in the rubber matrix and exist in the form of (-SS- bonds). The differences in the stable chemical forms and release mechanisms of sulfur and nitrogen make the release rate of SO2 and NO slower. During the dry mixing process, the single and cumulative concentrations of VOCs are higher than those of the wet mixing process, which may be because the surface of the rubber powder is more exposed and not fully covered by asphalt, PM 2.5 The emission of 20% was significantly increased, which may be caused by the thermal decomposition of the surface of rubber powder and aggregate particles. The concentration of SO2 and NO was relatively stable, showing a linear growth. In the wet mixing process, the VOCs concentration was slightly lower than that without adding aggregate, which may be because the aggregate has an adsorption effect on some organic volatiles. PM 2.5 The concentration increased, which may be due to the decomposition of volatiles on the aggregate surface. The concentrations of SO2 and NO changed slightly, but continued to accumulate. Based on these data and the emission law of asphalt smoke, a mathematical model describing the time-varying behavior of asphalt smoke emissions can be established to predict the peak emission period under various operating conditions, simulate the impact of different control strategies (such as temperature adjustment, chemical additives) on emission dynamics, and provide real-time feedback for the automated control system to optimize the capture and treatment process.

[0083]

[0084] Relying on the dynamic detection device of asphalt flue gas, based on the comprehensive environmental evaluation method, the heating and modification process of four materials with smoke suppression and energy saving were simulated and evaluated. The results show that the smoke suppression material B has a significant inhibitory effect on the four main components of asphalt flue gas, among which the inhibitory effect on SO2 is the most prominent. The energy-saving material B also shows a strong energy-saving effect, and the estimated and measured comprehensive evaluation values ​​are both the fourth energy-saving and emission reduction level; the smoke suppression effect of the smoke suppression material A is second, and the effect size on the four main components of asphalt flue gas is in the range of 3-7, but the energy-saving effect is only 3, and the estimated and measured comprehensive evaluation values ​​are both the second energy-saving and emission reduction level; the smoke suppression effect of the smoke suppression material C is the worst, and the effect size on the asphalt flue gas is only in the range of 1-3, but the energy-saving effect is 2 levels higher than that of the energy-saving material B, and the estimated and measured comprehensive evaluation values ​​are both the second energy-saving and emission reduction level. In summary, after comprehensive environmental evaluation of the three groups of smoke suppression and energy-saving materials, it can be determined that smoke suppression and energy-saving material B is the most preferred. The energy saving and smoke suppression effects of smoke suppression and energy-saving material B are better than those of material A and material C. It can be used as an effective smoke suppression and energy-saving material to improve the emission and energy consumption of asphalt flue gas.

[0085] The present invention proposes an asphalt fume collection and detection device, which selects four key components in asphalt fume as detection targets in accordance with the "General Technical Specifications for Environmentally Friendly and Odorless Asphalt" (DB32 / T 4650-2024) and industry standards. This device can perform a preliminary analysis of the main components of asphalt fume. Compared with the research method that only detects the overall concentration of asphalt fume, this technical route has significant advantages in scientificity. In addition, the device integrates an environmental simulation module, an asphalt fume collection and real-time detection module, a data processing module, and an asphalt waste gas treatment module, realizing the systematic integration of the generation, collection, detection, and treatment processes of asphalt fume in a single space, thereby realizing real-time collection and detection of asphalt fume, providing significant advantages in time resolution, revealing the time-varying laws of asphalt fume emissions, and helping to identify the generation mechanism of key pollutants and their environmental impacts. These data will help to establish more accurate emission control strategies, optimize industrial processes, and have important application value in environmental protection and occupational health.

[0086] The present invention proposes a comprehensive environmental assessment method, which aims to solve the problems of asphalt fume emissions and energy consumption. Based on the inhibition rate of the four main components in asphalt fume and the energy saving rate of energy consumption, this method constructs two quantitative evaluation indicators: the effect size of the smoke suppression rate (energy saving rate) and the weight factor. By introducing the energy-saving and emission reduction level, the improvement effect of asphalt fume emissions and energy consumption is systematically evaluated, so as to screen out efficient energy-saving and emission-reduction materials. The introduction of this method further improves the evaluation system for optimizing asphalt materials and reducing asphalt fume emissions under the background of energy conservation and emission reduction in transportation.

[0087] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
