[0041] According to the General Technical Specification for Environmental Clean Asphalt (DB32 / T 4650-2024) and industry standards, the present application selects four main components of asphalt fume as the detection target. Compared with the GC-MS technology, the present research simplifies the analysis process and realizes the preliminary analysis of the components of asphalt fume. At the same time, the asphalt fume collecting device designed in the present research integrates environmental simulation, asphalt fume collection and detection, data processing and asphalt waste gas treatment functions, and builds an environmental comprehensive evaluation system. The establishment of the system further promotes the standardization and systematization development of the collection, detection and treatment of asphalt fume.

[0042] As shown in Figure 1 The present embodiment provides an asphalt fume collecting and detecting device and a comprehensive environmental evaluation method thereof. The device is composed of an environmental simulation module, an asphalt fume collecting and real-time detecting module, a data processing module and an asphalt waste gas treatment module. In the simulation scene activation state, the present application uses gas sensor I, gas sensor II, gas sensor III and gas sensor IV to monitor the four main components in asphalt fume in real time. The dynamic detection system collects asphalt fume samples according to the gas flow theory, and generates dynamic images of the concentration of the four main gases changing with time through the data processing terminal. Further based on the proposed comprehensive environmental evaluation method, the simulation process is analyzed, so as to reveal the emission characteristics of asphalt fume under different scenes. According to the relevant standards, the present application selects four main components in asphalt fume for detection. Compared with the gas chromatography-mass spectrometry (GC-MS) and traditional gas detection device, the systematic structure of the device has the ability to monitor the key components in asphalt fume in real time, and has a significant advantage in time resolution. This function enables detailed analysis of the time-varying emission pattern of asphalt fume. By integrating the comprehensive environmental evaluation method, the device helps to screen out materials with better energy saving and emission reduction effect, thereby providing an experimental basis for energy saving and emission reduction of asphalt pavement.

[0043] Further, an asphalt fume collection and detection device comprises an environment simulation module, an asphalt fume collection and real-time detection module, a data processing module, and an asphalt waste gas treatment module. The asphalt fume collection and detection device realizes real-time collection and detection of data through systematic integration in a single space, and further utilizes an environment comprehensive evaluation method to evaluate energy-saving grades of asphalt material construction processes under different simulated environments.

[0044] (1) The environment simulation module is used to simulate the asphalt modification process and provide various simulated environments, including a detachable functional mechanical end (a shearing mechanical end, a mixing mechanical end, etc.), a power motor, and a temperature regulator. The simulated environments are realized by converting different mechanical ends and adjusting the temperature. The shearing mechanical end is connected to the power motor, and the front end of the shearing mechanical end is a honeycomb cylinder, which is detachable and has a maximum rotation speed of 7000 r / min. The mixing mechanical end is connected to the power motor, and the front end of the mixing mechanical end is a propeller, which is detachable and has a maximum rotation speed of 2000 r / min. The maximum temperature of the temperature regulator is 380℃.

[0045] (2) The asphalt fume collection and real-time detection module is used to detect the fume components to obtain detection data and transmit the detection data when the environment simulation module is started. The module includes an environment box, gas sensors I, II, III, and IV, and a wireless signal transmitter (or a data transmission line). The environment simulation module is placed inside the environment box, which is a cuboid (50 cm x 50 cm x 60 cm). The gas sensors are uniformly fixed on the front, back, left, and right sides of the environment box. The wireless signal transmitter (or the data transmission line) is connected to the gas sensors. When the environment simulation module is started and the gas concentration in the environment box reaches the detection threshold, the gas sensor I (VOCs), the gas sensor II (PM 2.5 ), the gas sensor III (SO2), and the gas sensor IV (NO) detect four main fume components, and the detection data are transmitted by the wireless signal transmitter (or the data transmission line).

[0046] (3) The data processing module is used to receive the detection data and perform a comprehensive environment evaluation of asphalt fume based on the detection data. The data processing module includes a wireless signal receiver (or a data transmission line) and a computer. The computer is externally connected to the environment box and receives and processes the data through the wireless signal receiver (or the data transmission line).

[0047] (4) asphalt waste gas treatment module, used for treating asphalt waste gas after the asphalt flue gas collection and real-time detection module works: the asphalt waste gas treatment module includes a gas guide pipe, a gas pump, a waste gas collector and the like. The gas pump is fixed to the top end surface of the environmental box, connected with the waste gas collector through the gas guide pipe. After the asphalt flue gas collection and real-time detection module works, the gas pump collects the asphalt waste gas into the waste gas collector through the gas guide pipe by the internal power motor. The waste gas collector is internally provided with a simple spraying device, which can simply treat the asphalt flue gas.

[0048] Example Two

[0049] The present embodiment also provides an environmental comprehensive evaluation method based on the asphalt flue gas collection and detection device. The environmental comprehensive evaluation method comprises the following steps: obtaining simulation environment data based on the asphalt modification process simulated by the environmental simulation module; obtaining detection data based on the simulation environment data by using the asphalt flue gas collection and real-time detection module to detect the flue gas components; obtaining processed data by processing the detection data based on the data processing module; obtaining the size of the smoke suppression rate and the weight factor of the asphalt flue gas by calculating the evaluation matrix and the weight factor constructed based on the processed data; obtaining the comprehensive environmental evaluation index by weighted summation calculation based on the size of the smoke suppression rate and the weight factor; and obtaining the comprehensive environmental evaluation result by dividing the comprehensive environmental index of the asphalt flue gas into five energy-saving and emission-reducing grades based on the comprehensive environmental evaluation index.

[0050] Further, the construction process of the evaluation matrix comprises: determining the weight factor of the asphalt flue gas component; determining the size of the inhibition rate of the smoke suppression material on the asphalt flue gas component; and arranging the size of the inhibition rate and the weight factor of the asphalt flue gas component in the form of a matrix to form the evaluation matrix of the asphalt smoke suppression and energy-saving material.

[0051] Further, each cell in the matrix is divided into left and right parts by a short symbol. The left part represents the size of the smoke suppression rate (energy-saving rate) a ij , and the lower half represents the weight factor of the flue gas component (energy-saving effect) b ij . The size of the smoke suppression rate (energy-saving rate) A is divided into 10 levels, and "10" is the highest level and "1" is the lowest level. The weight factor of the flue gas component (energy-saving effect) is also divided into 10 levels, and "10" represents the highest level and "1" represents the lowest level. The cumulative sum of each row element is obtained The cumulative sum of each column element is obtained The weighted sum of the matrix can be obtained by cumulative operation of the row vector and column vector elements , which is the total weighted score of the design scheme, i.e. CEAI. Taking an asphalt smoke suppression and energy-saving material as an example, the asphalt smoke suppression and energy-saving material evaluation matrix is shown in Table 1.

[0053]

[0054]

[0055] Further, the weight factor of the detection object is determined based on the air pollution composition and the asphalt fume composition in the Beijing-Tianjin-Hebei region; and the value of the action size is determined based on the action effect of the smoke suppression material (energy-saving material) in the large base research. As shown in Table 2, the weight factor value is shown. As shown in Table 3, the value and meaning of the smoke suppression rate (energy-saving rate) action size are shown.

[0059]

[0060] The comprehensive environmental index of the asphalt production process is divided into five levels from low to high, including:

[0061] When 0 < CEAI ≤ 80, the comprehensive environmental index is the first energy-saving and emission-reducing level;

[0062] When 80 < CEAI ≤ 200, the comprehensive environmental index is the second energy-saving and emission-reducing level;

[0063] When 200 < CEAI ≤ 320, the comprehensive environmental index is the third energy-saving and emission-reducing level;

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

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

[0066] Example Three

[0067] In this embodiment, an asphalt fume collection and detection device and a comprehensive environmental evaluation method thereof are provided, and the following example 1 is provided in this embodiment:

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

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

[0070] (3) Data processing module: collect the concentration of the four main components of bitumen smoke and the related data of the corresponding concentration corresponding to the temperature by computer, and further conduct comprehensive environmental evaluation of bitumen smoke.

[0071] (4) Bitumen smoke treatment module: after the bitumen smoke collection and real-time detection module is turned off, turn on the air pump, which collects the bitumen waste gas through the air guide pipe into the waste gas collector by the internal power motor, and starts the simple spraying facility inside the waste gas collector to simply process the bitumen smoke.

[0072] Comparative Example 1: only simulate the heating and modification process of bitumen, select to add smoke suppression material A, energy-saving material A, and smoke suppression and energy-saving material A (composite of smoke suppression material A and energy-saving material A) to perform heating and modification process respectively.

[0073] Comparative Example 2: only simulate the heating and modification process of bitumen, select to add smoke suppression material B, energy-saving material B, and smoke suppression and energy-saving material B to perform heating and modification process respectively.

[0074] Comparative Example 3: only simulate the heating and modification process of bitumen, select to add smoke suppression material C, energy-saving material C, and smoke suppression and energy-saving material C to perform heating and modification process respectively.

[0075] Test: in the environmental chamber, Example 1 simulates the heating, modification process, dry mixing and wet mixing process of 165℃, 100g A bitumen. After the generation, collection and detection of smoke, the data terminal processes the results, and according to the importance and size of the effect table, the final results are determined. The pollutant concentration in the bitumen smoke under different simulated environments of Example 1 is shown in Table 4, and the comprehensive environmental grade is shown in Table 5. The test results of heating and modification process after smoke suppression and energy-saving treatment of Comparative Examples 1-3 are shown in Table 6.

[0076] Table 4

[0077]

[0078] As shown in Table 4, the four different simulated environments have the same rule, the VOCs concentration accumulates the fastest, followed by PM 2.5, SO2 and NO concentrations grow relatively slowly but also show a continuous growth trend; after the modification of asphalt (crumb rubber modification), compared with the original heating process, PM 2.5 and VOCs concentrations increase significantly, which may be due to the carbon black and un-decomposed rubber particles in the crumb rubber contributing to PM 2.5 concentrations and the pyrolysis of rubber in the crumb rubber during heating intensifying the release of VOCs. SO2 and NO concentrations also increase to a certain extent, but at a slower rate, which may be due to the sulfur in the asphalt existing in the form of thiophene, which is easy to decompose and thus releases faster, while the sulfur and nitrogen in the crumb rubber are wrapped in the rubber matrix and exist in the form of (-S-S- bond), and the differences in the stable chemical forms of sulfur and nitrogen and the release mechanism make the release rate of SO2 and NO slower; in the dry mixing process, the single and cumulative concentrations of VOCs are higher than in the wet mixing process, which may be due to the fact that the surface of the crumb rubber is more exposed and not fully covered by asphalt, PM 2.5 emissions increase significantly, which may be caused by the thermal decomposition of the surface of the crumb rubber and aggregate particles, and the concentrations of SO2 and NO change relatively stably, showing a linear growth; in the wet mixing process, the VOCs concentration is slightly lower than in the case without aggregate, which may be because the aggregate has an adsorption effect on some organic volatile substances, PM 2.5 concentrations increase, which may be due to the decomposition of volatile substances on the surface of the aggregate, and the change in the concentrations of SO2 and NO is small, but still accumulates continuously. Based on these data and the emission rules of asphalt fumes, a mathematical model can be established to describe the behavior of asphalt fume emissions over time, to predict the peak emission period under various operating conditions, to simulate the effects of different control strategies (such as temperature adjustment, chemical additives) on the emission dynamics, and to provide real-time feedback for the automatic control system to optimize the capture and processing process.

[0083]

[0084] Based on the comprehensive environmental evaluation method, the heating and modification processes of four materials with smoke suppression and energy saving were simulated, and the evaluation was made. The results showed that the smoke suppression effect of smoke suppression material B on the four main components of asphalt smoke was obvious, among which the suppression effect on SO2 was the most prominent. Energy-saving material B also showed strong energy-saving effect, and the estimated and measured comprehensive evaluation values were both the fourth energy-saving and emission-reducing grade. The smoke suppression effect of smoke suppression material A was second, and the effect size of the four main components of asphalt smoke was in the range of 3-7, but the energy-saving effect was only 3, and the estimated and measured comprehensive evaluation values were both the second energy-saving and emission-reducing grade. The smoke suppression effect of smoke suppression material C was the worst, and the effect size of asphalt smoke was only in the range of 1-3, but the energy-saving effect was 2 higher than that of energy-saving material B, and the estimated and measured comprehensive evaluation values were both the second energy-saving and emission-reducing grade. In summary, after the comprehensive environmental evaluation of the three groups of smoke suppression and energy-saving materials, it can be determined that the smoke suppression and energy-saving material B is the best choice, and the effect of smoke suppression and energy-saving material B in energy saving and smoke suppression is better than that of materials A and C, which can be used as a smoke suppression and energy-saving material with obvious effect to improve the problem of asphalt smoke emission and energy consumption.

[0085] The present application provides a kind of asphalt smoke collection and detection device, which selects four key components in asphalt smoke as detection targets according to 《General Technical Specification for Environmental Purification Odorless Asphalt》 (DB32 / T 4650-2024) and industry standard. The device can preliminarily analyze the main components of asphalt smoke. Compared with the research method of detecting only the overall concentration of asphalt smoke, the technical route has a significant advantage in scientificity. In addition, the device integrates environmental simulation module, asphalt smoke collection and real-time detection module, data processing module and asphalt waste gas treatment module, realizes the systematic integration of asphalt smoke generation, collection, detection and treatment process in a single space, and then realizes the real-time collection and detection of asphalt smoke, provides a significant advantage in time resolution, reveals the time-varying law of asphalt smoke emission, and helps to identify the generation mechanism of key pollutants and its environmental impact. 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 application provides a comprehensive environmental evaluation method to solve the problem of asphalt smoke emission and energy consumption. Based on the inhibition rate of four main components in asphalt smoke and the energy-saving rate of energy consumption, two quantitative evaluation indexes are constructed: smoke suppression rate (energy-saving rate) and weight factor. By introducing energy-saving and emission-reducing grade, the improvement effect of asphalt smoke emission and energy consumption is systematically evaluated, so as to screen out efficient energy-saving and emission-reducing materials. The method further perfects the evaluation system of optimizing asphalt materials and reducing asphalt smoke emission under the background of traffic energy-saving and emission-reducing.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
