Description

Technical Field

[0001] The present invention relates to the field of atmospheric observation, and in particular to an atmospheric composition monitoring system suitable for navigation of ships. Background Art

[0002] Accurate and dynamic monitoring of marine atmospheric composition is increasingly important in global atmospheric monitoring. Traditional atmospheric composition monitoring methods are mostly based on fixed land-based observation stations. The ocean covers approximately 70% of the Earth's surface, and its atmospheric environment is complex and dynamic. The unique underlying surface is subject to air-sea interactions, making it difficult for fixed-site monitoring to fully reflect the temporal and spatial variations in marine atmospheric composition. To supplement atmospheric composition observation data from the oceans and polar regions, researchers often install various monitoring devices on ships for underway monitoring.

[0003] With the increasing frequency and diversity of marine scientific research tasks, and the continuous improvement of monitoring efficiency requirements, it is required that a single voyage survey cover more than 10 disciplines, including atmosphere, glaciers and sea ice, hydrology and meteorology, seabed topography and geomorphology, marine plankton, swimming organisms, microorganisms, bacteria and viruses, and marine chemistry. This requires that the atmospheric composition monitoring system be able to monitor black carbon concentrations, ozone concentrations, and greenhouse gas concentrations. The atmospheric composition monitoring system in the existing technology has many defects. On the one hand, the atmospheric composition monitoring system in the existing technology can only monitor a single type of atmospheric component; on the other hand, the existing greenhouse gas analysis device cannot analyze and collect multiple greenhouse gases at the same time.

[0028] The present invention provides an atmospheric composition monitoring system suitable for ships sailing. Figure 1 It is a connection diagram of an atmospheric composition monitoring system according to an embodiment of the present invention. During the navigation of a ship, since the ship will continue to shuttle between different sea areas, the atmospheric composition of different sea areas is quite different, and the ship will generate its own exhaust emissions when sailing, which requires accurate and real-time monitoring of the atmospheric composition. The atmospheric composition monitoring system of this embodiment may include a cabin 10, and the cabin 10 defines an installation space 11 for arranging an atmospheric composition monitoring device 200. Among them, a sampling tube 100 and an exhaust gas exhaust pipe 300 are generally provided on the cabin 10, which are respectively used to provide the atmospheric composition monitoring device 200 with external ambient air to be detected, and to discharge the exhaust gas generated by each component monitoring device.

[0029] Figure 2It is a cross-sectional view of an atmospheric composition monitoring system according to an embodiment of the present invention. Among them, the sampling tube 100 extends from the outside of the cabin 10 to the inside of the cabin 10, and is used to collect external ambient air. The part of the collection tube located inside the cabin 10 is provided with a plurality of air supply ports 110, and the plurality of air supply ports 110 are respectively connected to the air inlets of the black carbon monitoring device 210, the ozone analysis device 220 and one or more greenhouse gas analysis devices 240. External ambient air can be transported to each atmospheric composition monitoring device 200 through the plurality of air supply ports 110 to ensure that the atmospheric composition monitored by each atmospheric composition monitoring device 200 is the external ambient air collected at the same time. It can ensure the synchronization of data and improve the accuracy of data as much as possible.

[0030] Furthermore, the atmospheric composition monitoring system of this embodiment can also be provided with a U-shaped portion at the upper end of the sampling tube 100 to prevent solid particles in the air from naturally settling into the sampling tube 100, thereby preventing the atmospheric composition monitoring device 200 from being damaged by solid particles floating in the air. A rain cap 101 can also be connected to the air inlet end of the sampling tube 100 to prevent rainwater from entering the sampling tube 100. If rainwater enters the sampling tube 100, it may affect the detection accuracy of the atmospheric composition monitoring device 200. The provision of the rain cap 101 effectively prevents this from occurring, ensuring the accuracy of the monitoring results.

[0031] Furthermore, the atmospheric composition monitoring system of this embodiment may also include a filter device 102 within the rain cap 101 to purify the air entering the atmospheric composition monitoring device 200. The purified air reduces interference from impurities and pollutants on the monitoring, further ensuring the accuracy of the monitoring results of the atmospheric composition monitoring device 200. It also reduces the erosion of the atmospheric composition monitoring device 200 by these impurities, thereby extending the service life of the atmospheric composition monitoring device 200.

[0032] In some optional embodiments, the atmospheric composition monitoring system further includes an exhaust gas exhaust pipe 300 . Figure 3 This is a cross-sectional view of an atmospheric composition monitoring system according to another embodiment of the present invention. An exhaust gas exhaust pipe 300 extends from the interior of the cabin 10 to the exterior of the cabin 10. The black carbon monitoring device 210 and the ozone analyzer 220 are connected to the exhaust gas exhaust pipe 300 at a pipe section inside the cabin 10. The exhaust gas exhaust pipe 300 is used to discharge the exhaust gas generated by the black carbon monitoring device 210 and the ozone analyzer 220 into the external environment.

[0033] Furthermore, an exhaust fan 310 can be provided on the exhaust exhaust pipe 300. The suction generated by the exhaust fan 310 can quickly expel exhaust gas through the exhaust pipe 300 and into the outdoor environment. The exhaust pipe 300 can promptly remove exhaust gas generated by the atmospheric composition monitoring device 200, preventing exhaust gas accumulation and reducing exhaust gas corrosion and contamination of the atmospheric composition monitoring device 200. Multiple exhaust branch pipes 320 are provided on the body of the exhaust exhaust pipe 300 within the cabin 10. Each exhaust branch pipe 320 is connected to the corresponding atmospheric composition monitoring device 200 at one end and to the body of the exhaust pipe 300 at the other end. The provision of multiple exhaust branch pipes 320 enables targeted collection of exhaust gas generated by each atmospheric composition monitoring device 200. Since different monitoring devices may generate exhaust gas of different types or characteristics during operation, this one-to-one connection ensures that each type of exhaust gas is accurately collected, facilitating the normal operation of various devices within the cabin 10.

[0034] Furthermore, the atmospheric composition monitoring system of this embodiment can also be configured to have the sampling pipe 100 and the exhaust gas discharge pipe 300 disposed on the upper and lower sides of the cabin 10, respectively, and to extend the exhaust gas discharge pipe 300 to a location away from the atmospheric composition monitoring system. This allows for the timely discharge of exhaust gas and prevents pressure fluctuations caused by exhaust gas accumulation within the monitoring device, thereby avoiding interference with the normal operation of the device. It also reduces interference from external airflow on the sampling and exhaust gas discharge processes during navigation, thereby improving the accuracy of the detection data.

[0035] In some optional embodiments, the atmospheric composition monitoring system includes an ozone calibration device 230 . Figure 4 The figure is a schematic diagram of the gas circuit connection of an atmospheric composition monitoring system according to one embodiment of the present invention, wherein the standard gas outlet 231 of the ozone calibration device 230 is connected to the air inlet 221 of the ozone analysis device 220 for calibrating the ozone analysis device 220. The exhaust port 232 of the ozone calibration device 230 is connected to the exhaust gas exhaust pipe 300 for exhausting the exhaust gas generated by the ozone calibration device 230. By connecting the standard gas outlet 231 of the ozone calibration device 230 to the air inlet 221 of the ozone analysis device 220, the ozone analysis device 220 can be calibrated regularly. Calibrating the instrument with a standard gas of known concentration can correct the instrument's measurement deviation, ensuring that the ozone analysis device 220 can accurately measure the ozone concentration in the environment and provide reliable data for atmospheric composition monitoring.

[0036] Furthermore, a membrane filter 233 and activated carbon 234 can be installed at the air inlet 221 of the ozone analysis device 220 and the ozone calibration device 230. The membrane filter 233 and activated carbon 234 can effectively intercept impurities such as dust, particulate matter, and aerosols in the air. If these impurities enter the device, they may clog the pipes, affecting gas circulation, or adhere to sensors and components within the instrument, interfering with measurement accuracy and reducing the sensitivity and service life of the instrument.

[0037] In some optional embodiments, the greenhouse gas analysis device 240 includes a first greenhouse gas analysis device 400 for monitoring carbon dioxide, methane, and water in the external ambient air. Figure 5 : This is a schematic structural diagram of a first greenhouse gas analysis device 400 according to an embodiment of the present invention. The first greenhouse gas analysis device 400 includes a first greenhouse gas analyzer 410 and a first solenoid valve box 420. The first greenhouse gas analyzer 410 is used to analyze carbon dioxide, methane, and water in the external ambient air and generate a data report. The two ends of the first solenoid valve box 420 are respectively connected to an air supply port 110 and the first greenhouse gas analyzer 410, and are used to control the flow of external ambient air into the first greenhouse gas analyzer 410. The first solenoid valve box 420 can accurately control the flow of external ambient air into the first greenhouse gas analyzer 410. By adjusting the opening of the solenoid valve, the amount of gas entering the analyzer can be ensured to be stable and meet the working requirements of the instrument, thereby improving the accuracy and repeatability of the analysis results. For example, under different environmental conditions, such as when the air pressure and temperature change, the solenoid valve box can automatically adjust to ensure that the gas flow entering the analyzer is always maintained at the optimal state, avoiding measurement errors caused by unstable gas flow.

[0038] Furthermore, the first solenoid valve box 420 can also serve to protect the first greenhouse gas analyzer 410. It can automatically cut off the gas source when the instrument is not working or an abnormal situation occurs, preventing impurities, dust or harmful gases in the external environment from entering the analyzer, avoiding pollution, corrosion or damage to the sensors, pipelines and other components inside the instrument, and extending the service life of the instrument. At the same time, when the instrument is calibrated or maintained, the solenoid valve box can conveniently control the on and off of the gas, providing convenience for operation. In some optional embodiments, the greenhouse gas analysis device 240 also includes a second greenhouse gas analysis device 500 for monitoring carbon monoxide and nitrous oxide in the external ambient air. Figure 6: This is a schematic structural diagram of a second greenhouse gas analysis device 500 according to an embodiment of the present invention. The second greenhouse gas analysis device 500 includes a second greenhouse gas analyzer 510 and a second solenoid valve box 520. The second greenhouse gas analyzer 510 is used to analyze carbon monoxide and nitrous oxide in the external ambient air and generate a data report. The two ends of the second solenoid valve box 520 are respectively connected to an air supply port 110 and the second greenhouse gas analyzer 510, and are used to control the entry of external ambient air into the second greenhouse gas analyzer 510. Similar to the first greenhouse gas analysis device 400, the second solenoid valve box 520 in the second greenhouse gas analysis device 500 can also adjust the opening of the solenoid valve to ensure that the amount of gas entering the analyzer is stable and meets the working requirements of the instrument, and can also protect the second greenhouse gas analyzer 510.

[0039] Furthermore, a muffler 411 may be installed at the exhaust port of the first greenhouse gas analysis device 400 and the second greenhouse gas analysis device 500. The muffler 411 can buffer the pressure fluctuations and airflow impact during gas discharge, reducing wear, vibration, and stress on the analysis device itself and the connecting pipes, thereby extending the service life of the equipment and pipes, reducing maintenance costs and the risk of equipment failure.

[0040] In some optional embodiments, the greenhouse gas analysis device 240 further includes a plurality of greenhouse gas sampling components 600. Figure 7 : This is a schematic structural diagram of a greenhouse gas sampling assembly 600 according to an embodiment of the present invention. The greenhouse gas sampling assembly 600 is connected to the first solenoid valve box 420 and the second solenoid valve box 520, respectively, and is used to collect external ambient air for sampling. The greenhouse gas sampling assembly 600 includes a plurality of sampling bottles 610 for collecting external ambient air. The air inlet 611 of the sampling bottle 610 is connected to the first solenoid valve box 420 or the second solenoid valve box 520, and the air outlet 660 of the sampling bottle 610 is used to discharge the gas in the bottle to adjust the pressure in the bottle. The sampling bottle 610 is used to collect external ambient air and provides a stable sample source for greenhouse gas analysis. By connecting the air inlet 611 to the solenoid valve box, the sampling process can be precisely controlled to ensure that a representative air sample is collected. Moreover, during the sampling process, when the pressure in the sampling bottle 610 is too high, the gas in the bottle can be discharged through the air outlet 660 to adjust the pressure in the bottle, thereby preventing inaccurate sampling or damage to the sampling equipment due to excessive pressure, thereby ensuring the accuracy of sampling and the safety of the equipment.

[0041] Furthermore, the number of sampling bottles 610 can be multiple, and used to collect external ambient air of different concentrations. Figure 7 The two sampling bottles 610 shown in FIG can both jointly adjust the pressure in the sampling bottles 610 and respectively collect high-concentration and low-concentration external ambient air. Figure 5 and Figure 6 The four sampling bottles 610 shown are each connected to a control valve 640. Sampling bottles 2#, 3#, and 4# collect high-concentration, medium-concentration, and low-concentration ambient air, respectively. Multi-point calibration fully covers the instrument's operating range, improving calibration accuracy and measurement linearity. This allows for a more accurate determination of the relationship between the instrument's measured value and actual concentration, reducing measurement errors, improving calibration accuracy and measurement linearity, and resulting in more accurate and reliable measurement results.

[0042] Furthermore, sampling bottle 610 #5 can be used to store standard gas for daily use. Setting up a dedicated sampling bottle 610 to store standard gas for daily use for routine calibration makes instrument calibration more convenient and standardized. In daily use, the instrument can be calibrated regularly with this standard gas to ensure that the instrument is always in accurate working condition and improve measurement stability and consistency.

[0043] Furthermore, an installation position for the 1# sampling bottle 610 can be reserved before the 2# sampling bottle 610 for installing the 1# sampling bottle 610. The 1# sampling bottle 610 can be installed according to actual needs, which provides the possibility for expanding and adjusting the functions of the instrument and increases the flexibility of use. In some optional embodiments, the greenhouse gas sampling assembly 600 also includes a sampling pump 620 and a pressure gauge 630. The sampling pump 620 is used to promote the flow of external ambient air into the sampling bottle 610, and the pressure gauge 630 is connected to the air outlet 660 to monitor the air pressure in the sampling bottle 610 and adjust the speed of the sampling pump 620 according to the monitored air pressure value. The function of the sampling pump 620 is to promote the flow of external ambient air into the sampling bottle 610, and it can actively control the inflow speed and flow rate of the air to ensure the efficiency and accuracy of sampling. During the operation of the greenhouse gas sampling assembly 600, by adjusting the speed of the sampling pump 620, the amount of air entering the sampling bottle 610 can be accurately controlled according to actual needs to ensure that the collected sample is representative. For example, under different environmental conditions or for different sampling requirements, the appropriate sampling speed can be obtained by adjusting the rotation speed of the sampling pump 620 to avoid sample distortion caused by excessively fast or slow sampling speeds.

[0044] Furthermore, the pressure gauge 630 is connected to the air outlet 660 for monitoring the air pressure in the sampling bottle 610, and can obtain the pressure information in the sampling bottle 610 in real time. The rotation speed of the sampling pump 620 is adjusted according to the air pressure value obtained by monitoring, forming a closed-loop feedback control system. When the air pressure in the sampling bottle 610 is too high, the rotation speed of the sampling pump 620 is reduced to reduce the amount of air flowing in, thereby preventing the sampling bottle 610 from being damaged or affecting the sampling accuracy due to excessive pressure; when the air pressure is too low, the rotation speed of the sampling pump 620 is increased to increase the amount of air flowing in, so that the pressure in the sampling bottle 610 is maintained within an appropriate range. This real-time monitoring and feedback adjustment mechanism helps to maintain the stability and reliability of the sampling process, ensures that the pressure in the sampling bottle 610 is always in a safe and appropriate state, and thus improves the quality and accuracy of sampling.

[0045] In some optional embodiments, the greenhouse gas sampling assembly 600 further includes a control valve 640 and a flowmeter 650. The control valve 640 is disposed on the piping of the gas outlet 660 to adjust the opening of the gas outlet 660. The flowmeter 650 is disposed on the piping of the gas outlet 660 to coordinate with the control valve 640 in adjusting the opening of the gas outlet 660. The control valve 640 can directly adjust the opening of the gas outlet 660, thereby controlling the speed and flow rate of gas outflow. The combination of the flowmeter 650 enables more precise flow control, as the flowmeter 650 can monitor gas flow in real time and provide feedback to the operator or control system. Based on the readings of the flowmeter 650, the operator adjusts the opening of the control valve 640 to achieve and stabilize the gas flow at the desired precise value. This is crucial for ensuring sampling accuracy, as different analytical instruments have specific gas flow requirements. Only by precisely controlling the flow rate can the representativeness of the collected gas sample and the accuracy of subsequent analytical results be ensured.

[0046] Furthermore, the greenhouse gas sampling assembly 600 should also include a battery and a connecting tube between the sampling bottles 610. The battery is used to power the sampling pump 620, and the connecting tube is used to connect two adjacent sampling bottles 610. A valve can also be set on the connecting tube. The battery provides power to the sampling pump 620, so that the sampler does not need to rely on an external power socket and can be flexibly used in places such as the wild and polar regions where there is no mains power supply, greatly improving the mobility and applicability of the sampler. The connecting tube connects adjacent sampling bottles 610 so that the sampled gas can flow between different sampling bottles 610, so that the gas can be distributed, transferred or mixed according to actual needs. For example, the collected gas samples can be divided into multiple sampling bottles 610 for analysis of different projects, or the gases in multiple sampling bottles 610 can be collected into one bottle for unified processing. The flow of the sampled gas in the connecting tube can be precisely controlled by the valve to determine whether the gas flows and the direction and flow rate of the flow. During the sampling process, the valve can be flexibly opened or closed according to specific sampling requirements and experimental steps to achieve precise control of the sampled gas.

[0047] In some optional embodiments, there are multiple sampling bottles 610, each used to collect external ambient air of different concentrations. Considering that a single sampling bottle 610 may not be representative of the sample due to various factors (such as sampling location, sampling time, etc.), thereby affecting the accuracy and reliability of the data. Multiple sampling bottles 610 simultaneously collect samples of different concentrations, which can reduce this error to a certain extent. Through comprehensive analysis and comparison of multiple samples, the ambient air quality can be more accurately assessed, the credibility of the data can be improved, and a more reliable basis for environmental decision-making can be provided.

[0048] In some optional embodiments, the atmospheric composition monitoring system further includes an intake fan 120, disposed at the lower end of the sampling tube 100, for drawing ambient air into the atmospheric composition monitoring device 200. The intake fan 120 can actively draw ambient air into the sampling tube 100, accelerating air flow and significantly improving sampling efficiency compared to natural diffusion. Particularly in environments with slow air flow, such as indoors or in relatively enclosed spaces, the fan can ensure timely collection of representative air samples, enabling monitoring results to more quickly and accurately reflect the atmospheric composition of the current environment.

[0049] In some optional embodiments, the black carbon monitoring device 210 collects observation data in real time, generates a data file every day, and generates a log file at irregular intervals. The operator downloads the data collected by the black carbon monitoring device 210 at regular intervals to retain historical data.

[0050] Furthermore, during seasonal calibration, ozone analyzer 220 collects average observation data in real time. Ozone analyzer 220 generates data files monthly, and all files are written to the instrument's memory. Backup data is downloaded from the data backup computer at regular intervals. If ozone analyzer 220 is calibrated by ozone calibration device 230, data is also downloaded after each calibration.

[0051] Furthermore, first greenhouse gas analysis device 400 and second greenhouse gas analysis device 500 are equipped with built-in computers, which directly access data from the computers using a storage device. Observers regularly download the data collected and recorded by the instruments, back it up to the computer, and then back it up again using software. After appropriate processing and packaging, the data is then sent back monthly.
