Description

Technical Field

[0002] With the development of economic globalization, the process of industrialization and urbanization is accelerating, and the problem of air pollution is becoming increasingly serious, especially the problem of atmospheric particulate matter pollution, which has attracted widespread attention worldwide. Atmospheric particulate matter not only affects environmental quality, but is also closely related to human health. The increase in its concentration is positively correlated with the morbidity and mortality of respiratory and cardiopulmonary diseases. Therefore, effective control and governance of atmospheric particulate matter pollution is of great significance to protecting human health and improving environmental quality.

[0003] The pollution status of atmospheric particulate matter is related to many factors, among which pollution sources and meteorological conditions are two important influencing factors. When the distribution of pollution sources and their emissions are relatively stable, the concentration of atmospheric particulate matter is affected by various meteorological conditions. For example, changes in meteorological factors such as rainfall and temperature will significantly affect the diffusion conditions and spatiotemporal distribution of atmospheric particulate matter. When studying the correlation between particulate matter pollution and meteorological factors, tests are generally carried out directly in the outside world. Since external environmental factors cannot be actively regulated and multiple environmental factors are prone to change at the same time (such as humidity and temperature changing at the same time), the accuracy of the analysis results will be affected.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The heater 11 and the nozzle 13 are installed in the inner cavity of the first cavity 201. The water supply component 4 is installed on the workbench 1. The water supply component 4 includes a water tank and a water pump arranged inside the water tank. The outlet of the water pump is connected to the nozzle 13. The detector 29 is installed on the isolation cover 2. The detection end of the detector 29 extends into the inner cavity of the first cavity 201 and the second cavity 202, and the detector 29 is connected to the processing device 3. The detector 29 transmits the detected data to the processing device 3.

[0030] It should be noted that the isolation cover 2 is fixed to the top wall of the workbench 1 by bolts or other connection methods during use (the isolation cover 2 can be removed from the top of the workbench 1), and the first cavity 201 and the second cavity 202 are provided with an insulation layer (such as glass fiber insulation cotton). The simulated cavity can be set to multiple (such as three or four, only two are taken as an example in this application), and the heater 11 can also be replaced with a device with both heating and cooling functions, so that the air temperature can be reduced.

[0031] An analytical method for the correlation between particulate matter pollution and meteorological factors, the steps are as follows:

[0032] First, inject the gas to be detected (the gas to be detected refers to air containing particles) into the first cavity 201 and the second cavity 202 of the isolation cover 2, and change the environment inside the first cavity 201 according to different experimental requirements (for example, detecting the effect of temperature on particle concentration or detecting the effect of rainfall on particle concentration);

[0033] It should be noted that there are two ways to change the environment inside the first cavity 201. First, the heater 11 works to change the temperature inside the first cavity 201. Second, the water supply component 4 sends water to the nozzle 13 and sprays it out to simulate the precipitation environment inside the first cavity 201.

[0034] Second, after a period of time, the detector 29 detects the particle concentration inside the first cavity 201 and the second cavity 202 respectively, and transmits the detected data to the processing device 3. The processing device 3 compares and analyzes the two groups to obtain the correlation between particle pollution and meteorological factors.

[0035] It should be noted that a drainage hole 12 is provided on the workbench 1 . The drainage hole 12 is located in the inner cavity of the first cavity 201 . The drainage hole 12 is connected to a drainage pipe on which a valve is installed for draining water from the first cavity 201 .

An elastic member 19 (spring) is provided between the installation box 6 and the movable plate 18, and a linkage rod 20 is provided on the movable plate 18. The linkage The rod 20 extends to the outside of the installation box 6 and is connected to the connecting rod 7; when the water supply component 4 supplies water, the water of the water supply component 4 enters the inner cavity of the installation box 6 through the water pipe 5, and the water pushes the movable plate 18 to move, so that the end of the movable plate 18 does not contact the guide plate 17, and then the water flows out from the gap between the movable plate 18 and the guide plate 17 and enters the nozzle 13; the movement of the movable plate 18 will bring the linkage rod 20 and the connecting rod 7 to move together, so that the protective cover 14 covers the heater 11, and the sealing plate 15 enters the interior of the protective cover 14 to block the opening of the protective cover 14, so that when simulating rainfall, water will not spill onto the heater 11; and the protective cover 14 is driven to move by the flow force of water during water supply.

[0038] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A slide groove is provided at the connection portion between the isolation cover 2 and the connecting rod 7, through which the connecting rod 7 can move, so that the movement of the connecting rod 7 is not affected; a baffle 8 is provided on the side wall of the connecting rod 7, and the bottom of the baffle 8 is in contact with the top wall of the isolation cover 2. The baffle 8 covers the slide groove to ensure the closed environment of the first cavity 201.
