Description

TECHNICAL FIELD

[0001] The present application relates to an aerosol aging simulation device, in particular to an aerosol aging simulation system and simulation method for solid-liquid multi-component quantitative adhesion. BACKGROUND

[0002] Environmental aerosol mainly refers to solid or liquid particles dispersed and suspended in the atmosphere, which can cause atmospheric environmental pollution and trigger serious haze weather. The sources of primary aerosols directly discharged in production and life are diverse, and their microphysical properties and chemical compositions are very complex. Primary aerosols will undergo complex aging processes in the atmospheric environment, such as mutual collision and adhesion of different types of particles, heterogeneous reaction, hygroscopic growth, etc., to form secondary aerosols with complex structure and composition. In the characterization research of environmental aerosol, it is of great significance to reveal the aging mechanism of aerosol by designing an aging simulation device to realize the adhesion of different components to aerosol and the hygroscopic process of mixed particles.

[0003] The existing aerosol aging device has certain deficiencies in multi-component adhesion, quantitative control of wrapping material, and adhesion process design. In 2017, Fan Xiaolong et al. of Nanjing University of Information Engineering designed an aerosol aging system, which designed adhesion chambers for solid or oil-like and liquid substances, realized the adhesion of triethylene glycol and sulfuric acid to carbonaceous aerosols, but could not realize the sequential adhesion of two different phase substances to aerosols. In 2019, Du Lin et al. of Shandong University disclosed a device and method for wrapping organic matter on the surface of aerosol particles, which only realized the adhesion of aerosols based on the bubbling method, but could not accurately realize the control of adhesion amount. In order to better simulate the adhesion process of aerosols by different components and the hygroscopic growth process in the real atmospheric environment, it is necessary to design an aerosol aging simulation system that can realize the quantitative adhesion of solid-liquid multi-component.

[0047] like Figures 1 to 4 As shown, the aerosol aging simulation system for quantitative adhesion of solid and liquid multi-components of the present invention includes an aerosol input device, a first adhesion chamber 4, a first moisture absorption pipe 5, a second adhesion chamber 6, a second moisture absorption pipe 7, a vacuum pump 27, a solid / oily substance feeding device, a liquid feeding device, and a humidifier.

[0048] The aerosol input device is located at the beginning of the system. Ambient aerosols enter the system after pretreatment through the aerosol input device. The aerosol input device is then divided into two paths. One path is connected to the first attachment chamber 4 for the attachment of solid / oily substances. The first attachment chamber 4 is connected to the first moisture absorption pipe 5 for moisture absorption treatment of the aerosols. The other path is connected to the second attachment chamber 6 for the attachment of liquid substances. The second attachment chamber 6 is connected to the second moisture absorption pipe 7 for moisture absorption treatment of the aerosols. Both paths are driven by the negative pressure generated by the vacuum pump 27 at the end of the system. The aerosols that have moved to the vacuum pump 27 are discharged from the outlet of the vacuum pump 27 and out of the system.

[0049] The first attachment chamber 4 is connected to a solid / oily substance feeding device, which vaporizes the solid / oily substance and supplies it quantitatively to the first attachment chamber 4, thereby achieving quantitative attachment of the solid / oily substance.

[0050] The second adhesion chamber 6 is communicated with a liquid material feeding device, and the liquid material feeding device is used to gasify the liquid material and then quantitatively feed the gasified liquid material to the second adhesion chamber 6, so as to realize quantitative adhesion of the liquid material.

[0051] The first and second hygroscopic pipes 5 and 7 are communicated with a humidifier, and the humidifier is used to generate small water droplets and then introduce the small water droplets into the first or second hygroscopic pipe 5 or 7 to perform hygroscopic treatment on the aerosol in the first or second hygroscopic pipe 5 or 7.

[0052] As shown in Figure 2 The solid / oil material feeding device comprises a solid material inlet 8, a first particle filter 9, a solid material bin 10, a high-pressure pump 11 and a first gasification chamber 12 which are sequentially communicated, the first gasification chamber 12 is communicated with the first adhesion chamber 4 through a first two-way valve, and a first temperature sensor 13 is arranged on the first gasification chamber 12.

[0053] The first particle filter 9 is arranged between the solid material bin 10 and the solid material inlet 8, and is used to prevent other aerosols and the like in the atmospheric environment from entering the system and interfering with the experiment. In use, the solid or oil material is added into the solid material bin 10 through the solid material inlet 8, and the solid / oil material in the solid material bin 10 is driven into the first gasification chamber 12 by the high-pressure air pump, the first temperature sensor 13 is used to detect the temperature in the first gasification chamber 12, and since the thermocouple type heating belt is uniformly arranged outside the first gasification chamber 12, different temperatures are arranged at different positions to convert the solid phase material in the first gasification chamber 12 into gas phase, and the gas phase material in the first gasification chamber 12 is transported into the first adhesion chamber 4 through the first two-way valve.

[0054] The feeding amount of the solid or oil material is calculated according to the relationship between the dynamic viscosity and the flow rate. The calculation method is to use the formula and to calculate the flow rate of the solid or oil material in the pipeline, and then control the feeding time of the solid material bin 10 to control the amount of the solid or oil material, so as to achieve the purpose of quantitative adhesion, wherein π = 3.1415926; d is the pipe diameter; p is the density of the material; g is the acceleration of gravity; P is the pressure difference between the two ends of the pipeline; μ is the dynamic viscosity; L is the length of the pipeline. The pressure difference P between the two ends of the pipeline is calculated by the flow rate formula , wherein the flow rate V can be measured by connecting a flow measuring pipe between the high-pressure air pump and the first gasification chamber 12.

[0055] As shown in Figure 3As shown, the liquid feeding device comprises a liquid material inlet 15, a liquid tank 16, a high-pressure metering pump 17 and a second vaporization chamber 18 connected in sequence, the second vaporization chamber 18 is connected with the second adhesion chamber 6 through a second two-way valve 20, and a second temperature sensor 19 is arranged on the second vaporization chamber 18.

[0056] In use, the liquid material is added from the liquid material inlet 15 into the liquid tank 16, and the high-pressure metering pump 17 is used to deliver the liquid material into the second vaporization chamber 18. Since the thermocouple type heating belt is uniformly laid outside the second vaporization chamber 18, and the temperature in the second vaporization chamber 18 is detected by the second temperature sensor 19, different temperatures are set according to different materials, so as to convert the liquid material in the second vaporization chamber 18 into a gas phase. The gas phase material in the second vaporization chamber 18 is delivered into the second adhesion chamber 6 through the second two-way valve 20.

[0057] The high-pressure metering pump 17 is internally provided with a flow meter, which can measure the volume of the liquid material added each time, so as to achieve the purpose of quantitative adhesion. The amount of liquid material can be controlled according to the high-pressure metering pump 17. The high-pressure metering pump 17 is internally provided with a flow meter, the measurement range is 0.001~9.999ml / min, and the accuracy is ±0.1%. When the flow reaches the preset value, the feeding is stopped.

[0059] Two-thirds of the volume of ultrapure water or distilled water is added into the ultrapure water container 23, and the external air enters the ultrapure water container 23 through the third two-way valve 21 and the second particle filter 22. The second particle filter 22 can prevent particles in the air from entering the ultrapure water container 23 and causing pollution. The water temperature in the ultrapure water container 23 is maintained at about 29℃ by the heater 24, so as to avoid the generation of condensed water due to the large temperature difference between the inside and outside of the container. The external air enters the ultrapure water container 23 and enters the pipe below the liquid surface, so as to form bubbles in the water. After the bubbles break, a large amount of small water droplets are released. The small water droplets enter the first moisture absorption pipe 5 or the second moisture absorption pipe 7 through the pipe above the liquid surface, and are controlled by the fourth two-way valve 25 and the fifth two-way valve 26 to enter the first moisture absorption pipe 5 or the second moisture absorption pipe 7, so as to realize the rapid change of the relative humidity in the moisture absorption pipe within 15%~95%.

[0060] A first humidity sensor 44 and a second humidity sensor 45 are arranged on the first moisture absorption pipe 5 and the second moisture absorption pipe 7 respectively, and the opening and closing of the fourth two-way valve 25 and the fifth two-way valve 26 are controlled by the humidity sensors, so as to control the humidity in the first moisture absorption pipe 5 and the second moisture absorption pipe 7.

[0061] The aerosol input device comprises an aerosol inlet 1, a cutter and a neutralizer 3 connected in sequence, and the ambient aerosol enters through the aerosol inlet 1 and then sequentially passes through the cutter and the neutralizer 3 to pre-treat the aerosol.

[0062] The first moisture absorption pipe 5 and the second moisture absorption pipe 7 are specifically Nafion drying pipes. The Nafion drying pipe is a kind of semi-permeable membrane with selective water vapor, which has corrosion resistance and can quickly absorb water in gas or liquid phase.

[0063] The above structure is the basic structure of the aerosol aging simulation system for solid-liquid multi-component quantitative adhesion of the application, which can realize basic adhesion and moisture absorption treatment. That is, after the adhesion of a single solid / oily substance or the adhesion of a single liquid substance, the ambient aerosol is input into the system from the aerosol input device and moves along a path to complete the corresponding adhesion and moisture absorption treatment.

[0064] In addition, a first three-way valve 2914 is arranged on the pipeline between the first adhesion chamber 4 and the first moisture absorption pipe 5, the first three-way valve 2914 is connected with a second three-way valve 34 through a first branch 36, one port of the second three-way valve 34 is connected with the pipeline between the aerosol input device and the first adhesion chamber 4 through a second branch 37, and the other port of the second three-way valve 34 is connected with the pipeline between the aerosol input device and the second adhesion chamber 6 through a third branch 38; a third three-way valve 32 is arranged on the pipeline between the second adhesion chamber 6 and the second moisture absorption pipe 7, the third three-way valve 32 is connected with a fourth three-way valve 35 through a fourth branch 39, one port of the fourth three-way valve 35 is connected with the pipeline between the aerosol input device and the first adhesion chamber 4 through a fifth branch 40, and the other port of the fourth three-way valve 35 is connected with the pipeline between the aerosol input device and the second adhesion chamber 6 through a sixth branch 41.

[0065] Through the above arrangement, the aerosol passing through the attachment chamber can return to the front end of the attachment chamber to pass through the attachment chamber again for the second time of attachment, so that the aerosol can be subjected to quantitative attachment of multiple solid / oily substances or quantitative attachment of multiple liquid substances. At the same time, the aerosol passing through the first attachment chamber 4 can return to the front end of the second attachment chamber 6 to be subjected to quantitative attachment of solid / oily substances first and then quantitative attachment of liquid substances, and finally subjected to moisture absorption treatment. The aerosol passing through the second attachment chamber 6 can return to the front end of the first attachment chamber 4 to be subjected to quantitative attachment of liquid substances first and then quantitative attachment of solid / oily substances, and finally subjected to moisture absorption treatment.

[0066] A fifth three-way valve 30 is arranged on the pipeline between the first moisture absorption pipe 5 and the vacuum pump 27, and the port of the fifth three-way valve 30 is communicated with the pipeline between the aerosol input device and the first attachment chamber 4 through a seventh branch 42.

[0067] Through the above arrangement, the aerosol passing through the first attachment chamber 4 and the first moisture absorption pipe 5 can return to the front end of the first attachment chamber 4 after completing the quantitative attachment of the first solid / oily substance and the moisture absorption treatment, so as to be subjected to the quantitative attachment of the second solid / oily substance and the second moisture absorption treatment, and through repetition, the quantitative attachment of multiple solid / oily substances and multiple moisture absorption treatments can be realized. The aerosol passing through the second attachment chamber 6 and the second moisture absorption pipe 7 can return to the front end of the second attachment chamber 6 after completing the quantitative attachment of the first liquid substance and the moisture absorption treatment, so as to be subjected to the quantitative attachment of the second liquid substance and the second moisture absorption treatment, and through repetition, the quantitative attachment of multiple liquid substances and multiple moisture absorption treatments can be realized.

An eighth three-way valve 31 is arranged on the pipeline between the aerosol input device and the second attachment chamber 6, and the port of the eighth three-way valve 31 is communicated to the rear end of the second attachment chamber 6 through a tenth branch 47.

[0069] Through the above arrangement, the aerosol can be directly transported to the first moisture absorption pipe 5 or the second moisture absorption pipe 7 for moisture absorption treatment without passing through the attachment, or the aerosol can be introduced into the branch to select multiple paths by bypassing the first attachment chamber 4 or the second attachment chamber 6, so as to meet the needs of the aerosol aging simulation experiment.
