Description

Technical Field

[0001] This application belongs to the field of flue gas detection, specifically relating to a method, measurement system, and storage medium for measuring the visual sensory concentration of aerosols. Background Technology

[0002] In the tobacco industry and related research fields, accurate measurement of the visual concentration of smoke is crucial. Currently, optical measuring instruments are often used to obtain optical indicators related to smoke. While these indicators can reflect changes in the measured object to some extent, they generally lack clearly defined dimensions.

[0003] The lack of a clear dimension makes the traceability of measurement results poor, and data obtained from different measurement environments and instruments are difficult to compare and integrate effectively. For example, when the same type of optical measuring instrument is used to measure the same flue gas sample in different laboratories, the optical index values ​​obtained may differ due to slight differences in the instruments and measurement environments. Furthermore, due to the lack of a unified dimensional standard, it is impossible to accurately determine whether these differences are caused by the sample itself or by the measurement conditions.

[0004] This problem severely impacts the accuracy and reliability of measurement results, making it difficult for researchers to conduct in-depth analysis and research based on this data. Furthermore, in the quality control of tobacco products, the poor comparability of measurement results makes it difficult to formulate unified and accurate quality standards, thus affecting the standardized development of the entire tobacco industry. Therefore, how to transform these optical indicators into physical quantities with definite dimensions and clear meanings has become an urgent technical challenge. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a method, system and storage medium for measuring the visual sensory concentration of aerosols to solve the above problems.

[0011] Secondly, this application provides a system for measuring the visual sensory concentration of aerosols. The system is applied to the aforementioned method for measuring the visual sensory concentration of aerosols.

[0013] Thirdly, this application provides a computer system including a memory and a processor, and a computer program stored in the memory, wherein the processor executes the computer program to implement the steps of the above-described method for measuring the visual sensory concentration of aerosols.

[0014] Fourthly, this application provides a computer-readable storage medium storing a computer program / instructions thereon, which, when executed by a processor, implements the steps of the above-described method for measuring the visual sensory concentration of aerosols.

[0015] Fifthly, this application provides a computer program product, including a computer program / instructions, which, when executed by a processor, implement the steps of the above-described method for measuring the visual sensory concentration of aerosols.

[0016] As can be seen from the above technical solution, the advantages and positive effects of the aerosol visual sensory concentration measurement method proposed in this application are as follows:

[0017] Improving measurement accuracy and reliability: Through clear instrument and equipment requirements and strict operating procedures, this invention can transform dimensionless optical indicators obtained from optical measuring instruments into physical quantities with defined dimensions, reducing measurement errors and significantly improving the accuracy and reliability of measurement results.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0046] Please refer to Figure 1 and Figure 2 This application provides a system for measuring the visual concentration of aerosols. The system includes an aerosol generator 10, a measuring device, a flow control device, and a negative pressure device 60.

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

[0048] The negative pressure device 60, under the control of the flow control device, performs suction measurement of the aerosol in the measuring device.

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

[0050] The flow control range of the flow control device should be no less than 2 L / min, and the maximum permissible error should meet ±20 mL / min. Precise control of the gas flow rate ensures the stability of the gas flow rate during measurement, thereby improving the accuracy of the measurement results.

[0051] The aerosol generator 10 is capable of producing aerosols with a stable mass concentration exceeding 1000 μg / m³. A stable aerosol generator 10 is fundamental for obtaining reliable measurement data and provides a standard reference for subsequent measurements.

[0052] The measuring device may include a first aerosol trapping device 31 and a second aerosol trapping device 32.

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

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

[0055] It is understandable that the first sampling port 21 and the second sampling port 22 can also be the same sampling port, and a single concentration of aerosol can be measured 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 no less than 90%. This device is used to accurately collect aerosol particles of a specific size so that the aerosol concentration can be determined by subsequent mass measurement, thereby providing key data support for determining the visual concentration of flue gas.

[0057] Please refer to Figure 3 The aerosol visual sensory concentration measurement system of this application can be used to perform a method for measuring aerosol visual sensory concentration, as detailed below:

[0058] Step S1: Calibrate the suction flow rate of the aerosol-generated product and record the suction flow rate information.

[0059] According to such Figure 1 As shown in the connection diagram, the measurement system is sequentially connected to the aerosol generator 10, the first aerosol collection device 31, the second aerosol collection device 32, the flow control device, and the negative pressure device 60.

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

[0061] By activating the negative pressure device 60, slowly adjust the first flow control device 41 and the second flow control device 42, while observing the flow monitoring instrument, so that the flow controlled by the first flow control device 41 and the second flow control device 42 reaches the same value, and record the gas volume flow rate v (L / min) at this time. After calibration, turn off the negative pressure device 60.

[0062] Step S2: Perform a suction measurement on the aerosol of the aerosol-generated product to obtain the first concentration mass information.

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

[0064] Step S2 includes:

[0065] Step S21: Start the negative pressure device 60 to perform a first concentration measurement of the aerosol.

[0066] Step S22: Obtain the first aerosol optical parameters measured by suction at the first concentration.

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

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

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

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

[0071] Immediately shut off the negative pressure device 60, and immediately place the first aerosol collection device 31 back on the electronic balance for weighing, recording the mass as m1. That is, the mass of the first aerosol at the first concentration is m1 - m0.

[0072] During the 10-minute measurement process, the measuring device continuously measures the optical parameters of the first aerosol, 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 as η1 and I1, respectively.

[0073] Step S3: Perform a second concentration measurement on the aerosol generated from the aerosol product to obtain the second concentration mass information.

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

[0075] Step S3 includes:

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

[0077] Step S32: Obtain the second aerosol optical parameters measured by suction at the second concentration.

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

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

[0080] Then, the aerosol generator 10 is adjusted to a high concentration level. After the aerosol concentration stabilizes, the negative pressure device 60 is turned on and timed for 10 minutes. The second aerosol optical parameters measured by the measuring device are recorded. The second aerosol optical parameters include the average values ​​of absorbance and scattering values, which are denoted as η2 and I2, respectively.

[0081] Immediately after the measurement was completed and the negative pressure device was turned off (60°C), the mass of the nanoscale aerosol collection device was weighed using an electronic balance and recorded as m2. Another set of key data was obtained through high-concentration measurements to provide a basis for subsequent calculations.

[0082] Step S4: Based on the suction flow rate information, calculate the aerosol concentration data by combining it with the first concentration mass information and the second concentration mass information.

[0083] Step S4 includes:

[0084] Step S41: Based on the suction flow rate information, the first concentration mass information, and the second concentration mass information, calculate the aerosol visual sensory value simultaneously.

[0085] Solve the following system of two linear equations in two variables:

[0086] (1)

[0087] in, The mass of the aerosol at the first concentration. This refers to the gas volumetric flow rate of the flow control device. The absorbance is the first aerosol optical parameter. The scattering value is the optical parameter of the first aerosol.

[0088] (2)

[0089] in, The mass of the second concentration of aerosol, This refers to the gas volumetric flow rate of the flow control device. The absorbance is the second aerosol optical parameter. This represents the scattering value of the second aerosol optical parameter.

[0090] Solving equations (1) and (2) simultaneously yields the coefficients of the aerosol visual sensory setpoint. and .

[0091] These two coefficients can immediately establish a link between optical parameters (absorbance and scattering value) and actual aerosol mass concentration, thereby enabling a fixed value for the visually perceived concentration of flue gas.

[0092] Step S42: Determine aerosol concentration data based on aerosol visual sensory values ​​and aerosol optical parameters.

[0093] The coefficients for the visual sensory determination of aerosols were obtained through mathematical calculations. and .

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

[0095] That is, the calibrated smoke mass concentration is

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

[0097] It is understandable that, in the absence of smoke, the transmittance signal is 1, and the measured transmittance value is the transmittance. Furthermore, the amount of smoke is proportional to the absorbance A and the scattering value.

[0098] Therefore, the transmittance signal can be processed into an absorbance signal using the following formula (3).

[0099] (3)

[0100] in, Absorbance This is the transmission value.

[0101] It is understood that this application obtains aerosol visual sensory values ​​that are related to optical parameters by collecting aerosol measurement information at different concentrations and making comparative calculations. Based on the aerosol visual sensory values, the dimensionless optical indicators measured by optical measuring instruments are transformed into physical quantities with definite dimensions and clear meanings, thereby improving the accuracy and reliability of the measurement results and enhancing the comparability and wide applicability of the data.

[0102] It should be noted that in the measurement system and measurement method of this application, a negative pressure device 60 that meets the requirements of a negative pressure value of (60 ± 5) kPa and a negative pressure drainage flow rate of 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 rate.

[0103] Select a flow control device with a flow control range of not less than 2L / min and a maximum permissible error of ±20mL / min. Also, calibrate it before use to ensure the accuracy of flow control.

[0104] Prepare an aerosol generator 10 capable of producing stable aerosols with a mass concentration higher than 1000 μg / m³, and debug it to ensure that stable aerosols can be produced under different concentration settings.

[0105] A nanoscale aerosol capture device capable of effectively trapping aerosol particles with a diameter of 15nm and above with a trapping efficiency of not less than 90% is adopted, and its trapping performance is checked before use to ensure that it meets the standards.

[0106] A timer 50 with a measurement range of 0.1s-30min and a maximum permissible error of ±0.1s was selected, along with an electronic balance with a measurement range of (0-00)mg and a maximum permissible error of ±0.01g. Both were calibrated to ensure the accuracy of the measurement.
