Description

TECHNICAL FIELD

[0001] The application belongs to the field of flue gas detection, and particularly relates to a method and system for measuring the visual sensory concentration of aerosol, and a storage medium. BACKGROUND

[0002] In the tobacco industry and related research fields, accurate measurement of the visual sensory concentration of flue gas is of great importance. Currently, optical measuring instruments are often used to obtain optical indicators related to flue gas. These indicators can reflect the changes of the measured object to some extent, but they generally lack a clear dimension.

[0003] The lack of a clear dimension makes the traceability of the measurement results poor, and the data obtained by different measuring environments and different instruments are difficult to effectively compare and integrate. For example, when the same type of optical measuring instrument is used in different laboratories to measure the same type of flue gas sample, due to the subtle differences in the instruments and the different measuring environments, the optical indicator values obtained may be different, and due to the lack of a unified dimension standard, it is not possible to accurately determine whether these differences are caused by the sample itself or the measurement conditions.

[0004] This problem seriously affects the accuracy and reliability of the measurement results, making it difficult for researchers to conduct in-depth analysis and research based on these data. At the same time, in the quality control link of tobacco products, due to the poor comparability of the measurement results, it is difficult to develop unified and accurate quality standards, thereby affecting the standardized development of the entire tobacco industry. Therefore, how to convert these optical indicators into physical quantities with a certain dimension and clear meaning has become a technical problem that needs to be solved. SUMMARY

[0005] Therefore, the present application aims to provide a method and system for measuring the visual sensory concentration of aerosol, and a storage medium, to solve the above problems.

[0011] In a second aspect, the present application provides a measurement system of aerosol visual sensory concentration, which is applied to the measurement method of aerosol visual sensory concentration described above, and includes: an aerosol generating device, a measurement device, a flow control device, and a negative pressure device. The aerosol generating device is used to generate aerosol, and is provided with a first sampling port and a second sampling port. The first sampling port and the second sampling port are independently connected to the measurement device.

[0012] Further, the measurement device includes a first aerosol trapping device and a second aerosol trapping device. The first aerosol trapping device is connected to the first sampling port and is used to obtain the first concentration quality information of the aerosol. The second aerosol trapping device is connected to the second sampling port and is used to obtain the second concentration quality information of the aerosol.

[0013] In a third aspect, the present application provides a computer system, which includes a memory, a processor, and a computer program stored in the memory. The processor executes the computer program to implement the steps of the measurement method of aerosol visual sensory concentration described above.

[0014] In a fourth aspect, the present application provides a computer readable storage medium, which stores a computer program / instruction. When the computer program / instruction is executed by a processor, the steps of the measurement method of aerosol visual sensory concentration described above are implemented.

[0015] In a fifth aspect, the present application provides a computer program product comprising computer programs / instructions which, when executed by a processor, implement the steps of the above-mentioned method for measuring the visual sensory concentration of aerosol.

[0016] From the above technical solutions, the method for measuring the visual sensory concentration of aerosol provided by the present application has the following advantages and positive effects:

[0017] Improving measurement accuracy and reliability: By clear instrument requirements and strict operation procedures, the present application can convert the optical indicators obtained by optical measuring instruments, which lack clear dimensions, into physical quantities with determined dimensions, reducing measurement errors and greatly improving the accuracy and reliability of measurement results.

[0045] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0046] Please refer to Figure 1 and Figure 2 The present application provides an aerosol visual sensory concentration measurement system, which comprises an aerosol generating device 10, a measurement device, a flow control device and a negative pressure device 60.

[0047] The aerosol generating device 10 is used to generate aerosol, and the aerosol generating device 10 is provided with a first sampling port 21 and a second sampling port 22, and the first sampling port 21 and the second sampling port 22 are independently connected to the measurement device.

[0048] The negative pressure device 60 is controlled by the flow control device to suck and measure the aerosol in the measurement device.

[0049] Among them, the negative pressure device 60 needs to have a stable negative pressure value, and the negative pressure value should be (60 ± 5) kPa, and the negative pressure drainage flow should be not less than 10 L / min. The negative pressure device 60 provides stable gas flow power for the entire measurement system, ensuring that the aerosol and smoke can flow along the set path.

[0050] The flow control range of the flow control device should be not less than 2 L / min, and the maximum allowable error needs to meet ±20 mL / min. By accurately controlling the gas flow, the stability of the gas flow during the measurement process is ensured, thereby improving the accuracy of the measurement results.

[0051] The aerosol generating device 10 can produce aerosol with stable mass concentration, and the aerosol mass concentration is higher than 1000 μg / m³. The stable aerosol generating device 10 is the basis for obtaining reliable measurement data, and provides a standard reference for subsequent measurement.

[0052] The measurement device can include a first aerosol trapping device 31 and a second aerosol trapping device 32.

[0053] Specifically, the first aerosol trapping device 31 is connected to the first sampling port 21, and the first sampling port 21 can be used to obtain the first concentration mass information of the aerosol.

[0054] The second aerosol trapping device 32 is connected to the second sampling port 22, which can be used to obtain the second concentration mass information of the aerosol.

[0055] It can be understood that the first sampling port 21 and the second sampling port 22 can also be the same sampling port, and the single concentration aerosol measurement is carried out separately at different times.

[0056] The aerosol trapping device can effectively trap aerosol particles with a diameter of 15 nm and above, with a trapping efficiency of not less than 90%. The device is used to accurately collect aerosol particles of a specific particle size, so as to determine the aerosol concentration by subsequent mass measurement, and to provide key data support for the value of the visual sensory concentration of smoke.

[0057] Please refer to Figure 3 The aerosol visual sensory concentration measurement system of the present application can be used to perform the aerosol visual sensory concentration measurement method, which is specifically as follows:

[0058] Step S1: Calibrate the puffing flow of the aerosol generating article and record the puffing flow information.

[0059] According to the connection mode as Figure 1 shown, the measurement system is connected in sequence to the aerosol generating device 10, the first aerosol trapping device 31, the second aerosol trapping device 32, the flow control device and the negative pressure device 60.

[0060] During the connection process, it is ensured that the interfaces between the devices are well sealed to prevent gas leakage from affecting the measurement results.

[0061] By starting the negative pressure device 60, the first flow control device 41 and the second flow control device 42 are slowly adjusted, and the flow monitoring instrument is observed at the same time, so that the flow controlled by the first flow control device 41 and the second flow control device 42 reaches the same value, and the gas volume flow v (L / min) at this time is recorded. After calibration, the negative pressure device 60 is turned off.

[0062] Step S2: Measure the aerosol of the aerosol generating article at the first concentration, and obtain the first concentration mass information.

[0063] The first concentration mass information includes the first aerosol optical parameter and the first aerosol mass.

[0064] Step S2 includes:

[0065] Step S21: Start the negative pressure device 60 to measure the aerosol at the first concentration.

[0066] Step S22: Obtain the first aerosol optical parameter of the suction measurement at the first concentration.

[0067] Step S23: Obtain the first aerosol mass of the suction measurement at the first concentration.

[0068] Specifically, the initial mass of the nanoscale aerosol trapping device is accurately weighed using an electronic balance, denoted as m0. This step is the basis for subsequent mass change calculation.

[0069] Turn on the aerosol generating device 10 and adjust it to a low concentration level.

[0070] Closely observe the aerosol concentration monitoring instrument. After the aerosol concentration is stably displayed within the set low concentration range, start the negative pressure device 60 again, and simultaneously start the timer 50.

[0071] Quickly turn off the negative pressure device 60 and immediately place the first aerosol trapping device 31 on the electronic balance again to weigh, and record the mass as m1. That is, the first aerosol mass at the first concentration is m1- m0.

[0072] During the 10-minute measurement process, the measurement device continuously measures the first aerosol optical parameters, such as absorbance and scattering value. After the measurement is completed, the average values of absorbance and scattering value within the 10 minutes are calculated and recorded, denoted as η1 and I1, respectively.

[0073] Step S3: Perform a suction measurement at a second concentration on the aerosol of the aerosol generating article to obtain second concentration mass information.

[0074] The second concentration mass information includes second aerosol optical parameters and second aerosol mass.

[0075] Step S3 includes:

[0076] Step S31: Start the negative pressure device 60 to perform a suction measurement at a second concentration on the aerosol.

[0077] Step S32: Obtain the second aerosol optical parameter of the suction measurement at the second concentration.

[0078] Step S33: Obtain the second aerosol mass of the suction measurement at the second concentration.

[0079] Specifically, the first aerosol trapping device 31 is replaced with a second aerosol trapping device 32, and the previous initial mass measurement and flow calibration steps are repeated.

[0080] Then, the aerosol generating device 10 is adjusted to a high concentration level, and after the aerosol concentration is stable, the negative pressure device 60 is opened for 10 minutes, and the second aerosol optical parameter measured by the measuring device is recorded, the second aerosol optical parameter including the average values of the absorbance and the scattering value, denoted as η 2 and I 2 respectively.

[0081] After the negative pressure device 60 is turned off at the end of the measurement, the mass of the nanoscale aerosol trapping device is immediately weighed using an electronic balance, denoted as m 2. Another set of key data is obtained through the high concentration measurement, which provides a basis for subsequent calculation.

[0082] Step S4: Based on the puffing flow information, the first concentration mass information and the second concentration mass information are calculated respectively to obtain the aerosol concentration data.

[0083] Step S4 includes:

[0084] Step S41: According to the puffing flow information, the first concentration mass information and the second concentration mass information, the aerosol visual sensory value is calculated.

[0085] The following two linear equations are solved simultaneously:

[0086] (1)

[0087] Wherein, is the aerosol mass of the first concentration, is the gas volume flow of the flow control device, is the absorbance of the first aerosol optical parameter, is the scattering value of the first aerosol optical parameter.

[0088] (2)

[0089] Wherein, is the aerosol mass of the second concentration, is the gas volume flow of the flow control device, is the absorbance of the second aerosol optical parameter, is the scattering value of the second aerosol optical parameter.

[0090] The simultaneous solution of formula (1) and formula (2) can obtain the coefficients of the aerosol visual sensory value and .

[0091] The two coefficients can immediately establish a connection between the optical parameters (absorbance and scattering value) and the actual aerosol mass concentration, and further realize the value of the visual sensory concentration of the smoke.

[0092] Step S42: determining the aerosol concentration data according to the aerosol visual sensory value and the aerosol optical parameter.

[0093] The coefficient of the aerosol visual sensory value is obtained by mathematical calculation and .

[0094] After calibration, = -0.006094, = 0.0533053.

[0095] That is, the smoke mass concentration obtained by calibration is

[0096] Wherein, the transmission background light signal is 1, T is the transmission value measurement result, and I2 is the scattering signal measurement result.

[0097] It can be understood that, in the state without smoke, the transmittance signal is 1, the transmission value obtained by measurement is the transmittance, and the smoke amount is proportional to the absorbance A and proportional to the scattering value.

[0098] Therefore, the transmission value signal can be processed into the absorbance signal according to the following formula (3).

[0099] (3)

[0100] Wherein, is the absorbance, is the transmission value.

[0101] It can be understood that, by collecting and comparing the aerosol measurement information at different concentrations, the present application obtains the aerosol visual sensory value related to the aerosol concentration and the optical parameter, converts the optical index measured by the optical measuring instrument into a physical quantity with a certain dimension and a clear meaning according to the aerosol visual sensory value, so as to improve the accuracy and reliability of the measurement result, and enhance the comparability and wide applicability of the data.

[0102] It should be noted that, in the measurement system and method of the present application, the negative pressure device 60 meeting the requirements of negative pressure value (60 ± 5) kPa and negative pressure drainage flow not less than 10 L / min is preferred, and it is ensured that it is calibrated before measurement to ensure the stability of the negative pressure value and flow.

[0103] The flow control device with flow control range not less than 2 L / min and maximum allowable error meeting ± 20 mL / min is selected, and it is also calibrated before use to ensure the accuracy of flow control.

[0104] Prepare the aerosol generating device 10 capable of generating stable aerosol with a mass concentration higher than 1000 μg / m³, debug it, and ensure that it can generate stable aerosol at different concentration settings.

[0105] Use a nanometer aerosol trapping device that can effectively trap aerosol particles with a diameter of 15 nm and above with a trapping efficiency of not less than 90%, and check whether its trapping performance meets the standard before use.

[0106] Select a timer 50 with a measurement range of 0.1 s-30 min and a maximum allowable error of ±0.1 s, and an electronic balance with a measurement range of (0-00) mg and a maximum allowable error of ±0.01 g, and perform precision verification on both to ensure the accuracy of the measurement.
