Description

Technical Field

[0001] The utility model relates to the field of monitoring equipment, in particular to a monitoring device for carbon emissions in water. Background Art

[0002] Inland waters are important sources of carbon emissions and play an important role in the global carbon cycle. China has a vast land area and diverse climate conditions, with a large number of natural and artificial water bodies. The emissions of dissolved carbon dioxide (CO2) and methane (CH4) in these inland water systems are severely disturbed by global climate change and human activities, and are of global importance due to their high carbon emission fluxes. Therefore, it is necessary to monitor carbon emissions in water.

[0003] However, traditional methods for detecting carbon emissions in water rely on frequent manual operations, resulting in large fluctuations and instability in measurement results. Moreover, traditional methods usually rely on intermittent sampling, which can only provide data with limited time and space resolution. However, carbon emissions in inland waters exhibit strong spatiotemporal heterogeneity, especially in the long-term scenario where flow and temperature show strong influence and correlation. Considering that short-term carbon emission peaks (such as during rainfall events) may be of great significance to the overall carbon balance of rivers and their potential correlation with coping with climate change, only continuous data can provide sufficient resolution. Therefore, how to provide effective data for monitoring carbon emissions in water has become an urgent technical problem to be solved. Summary of the Utility Model

[0044] Please refer to Figure 1 - Figure 2 , an embodiment of a carbon emission monitoring device in water provided in the embodiment of the present utility model includes: a collection module 1, a water vapor balancer 2, a humidity exchanger 3, a greenhouse gas analyzer 4, and a power supply module 5; the collection module 1 is arranged in the water area to be measured and is connected to the water vapor balancer 2 for collecting the sample water of the water area to be measured and transmitting the sample water to the water vapor balancer 2; the water vapor balancer 2 is used for receiving the sample water and converting the sample water into water vapor; the humidity exchanger 3 is connected to the water vapor balancer 2 for extracting the water vapor and drying the water vapor to obtain a sample gas stream; the greenhouse gas analyzer 4 is connected to the humidity exchanger 3 for extracting and detecting the sample gas stream and outputting greenhouse gas concentration data; the power supply module 5 is respectively connected to the collection module 1, the water vapor balancer 2, the humidity exchanger 3, and the greenhouse gas analyzer 4 for supplying power to the collection module 1, the water vapor balancer 2, the humidity exchanger 3, and the greenhouse gas analyzer 4.

[0045] It should be noted that the water area to be measured refers to the water area where carbon emission monitoring is required, which can be determined according to the monitoring requirements. The types of the water area to be measured can be streams, lakes, etc. The sample water refers to the water in the water area to be measured. The greenhouse gas concentration data includes the concentrations of CO2 and CH4. In this embodiment, the greenhouse gas analyzer 4 can adopt a non-dispersive infrared greenhouse gas analyzer 4 on the market, which has the function of detecting the greenhouse gas concentration and can measure CH4 and CO2 simultaneously. Among them, the measurement range of CH4 is 0-100 ppm, and the measurement range of CO2 is 0-1000 ppm. And this instrument has a data storage function, and the detected greenhouse gas concentration data can be stored inside the instrument, which is suitable for long-term measurement. The water vapor balancer 2 can enhance the gas exchange efficiency.

[0046] The working principle of this embodiment is as follows:

[0047] The sampling module 1 samples the sample water in the water area to be measured. The water vapor balancer 2 can be used to convert the sample water from a liquid state to a gaseous state to obtain water vapor. The humidity exchanger 3 is used to dry the water vapor to further remove the moisture in the water vapor and obtain a sample gas stream. The greenhouse gas analyzer 4 detects the sample gas stream to obtain the greenhouse gas concentration data.

[0048] This embodiment constructs the connection of the sampling module 1, the water vapor balancer 2, the humidity exchanger 3, and the greenhouse gas analyzer 4 to form a closed-loop air flow channel, so that the greenhouse gas concentration data detected by the greenhouse gas analyzer 4 can effectively reflect the carbon emission situation of the water area to be measured. Therefore, it provides more effective data for the research on water area carbon emissions.

[0049] In this embodiment, the sampling module 1 is used to sample the sample water in the water area to be measured and completes the sampling of the sample water. The water vapor balancer 2 is used to extract the sample water in the sampling module 1 and convert the sample water into water vapor, realizing the conversion of the sample water for measurement. The humidity exchanger 3 is used to extract the water vapor in the water vapor balancer 2 and dry the water vapor to obtain a sample gas stream, realizing the further conversion of the sample water. The greenhouse gas analyzer 4 is used to extract and detect the sample gas stream in the humidity exchanger 3 and output the greenhouse gas concentration data, completing the detection of the concentration of the greenhouse gas dissolved in the water area to be measured and providing effective data for the monitoring of carbon emissions in water. The power supply module 5 is used to provide energy for the sampling module 1, the water vapor balancer 2, the humidity exchanger 3, and the greenhouse gas analyzer 4, so that the sampling module 1, the water vapor balancer 2, the humidity exchanger 3, and the greenhouse gas analyzer 4 can work continuously for a long time, and then obtain the continuous greenhouse gas concentration data contained in the water, that is, obtain the continuous monitoring data results of carbon emissions in water, providing more effective monitoring data of carbon emissions in water for the research on water area carbon emissions.

[0050] In a specific embodiment, the acquisition module 1 includes a water pump 11 and a flow meter 12;

[0051] The water pump 11 is arranged in the water area to be measured and is connected to the flow meter 12;

[0052] The flow meter 12 is connected to the water-vapor balancer 2.

[0053] It should be noted that the water pump 11 is used to extract the sample water in the water area to be measured. The flow meter 12 is arranged in the pipeline between the water pump 11 and the water-vapor balancer 2 and is used to measure the flow rate of the sample water in the pipeline.

[0054] In a specific embodiment, it further includes a perforated metal cage; a filter net is wrapped outside the perforated metal cage;

[0055] The perforated metal cage is arranged in the water area to be measured, and the water pump 11 is arranged inside the perforated metal cage.

[0056] It should be noted that wrapping a filter net around the perforated metal cage can serve as a coarse filter. Therefore, in this embodiment, by arranging the water pump 11 inside the perforated metal cage, it is possible to prevent the water pump 11 from sucking in impurity particles (such as particulate organic carbon POC), which may affect the detection effect.

[0057] In an example, the filter net can be made of plastic.

[0058] In a specific embodiment, the flow rate of the sample water can be 2 - 3 L / min.

[0059] In a specific embodiment, a nozzle 21 is arranged at the top of the water-vapor balancer 2;

[0060] One end of the nozzle 21 is connected to the flow meter 12;

[0061] The other end of the nozzle 21 is suspended inside the water-vapor balancer 2;

[0062] First pipelines 22 and second pipelines 23 are arranged on both sides of the nozzle 21;

[0063] One end of the first pipeline 22 is arranged outside the water-vapor balancer 2 and is connected to the humidity exchanger 3; the other end of the first pipeline 22 is suspended inside the water-vapor balancer 2;

[0064] One end of the second pipeline 23 is arranged outside the water-vapor balancer 2 and is connected to the humidity exchanger 3.

[0065] It should be noted that as Figure 2As shown, the nozzle 21 is an inverted funnel shape that is narrow at the top and wide at the bottom. Among them, the narrow end is arranged outside the water vapor balancer 2 and is connected to the flowmeter 12 for receiving sample water. The wide end is arranged inside the water vapor balancer 2 for spraying the sample water into the interior of the water vapor balancer.

[0066] The first pipeline 22 and the second pipeline 23 are respectively arranged on both sides of the nozzle 21. Among them, the first pipeline 22 is inserted into the interior of the water vapor balancer 2 from the top of the water vapor balancer 2. One end of the first pipeline 22 located above the top of the water vapor balancer 2 is connected to the humidity exchanger 3. The second pipeline 23 is inserted into the water vapor balancer 2 from the top of the water vapor balancer 2 and is flush with the inner plane of the water vapor balancer 2. One end of the second pipeline 23 located above the top of the water vapor balancer 2 is connected to the humidity exchanger 3 through an air pipe.

[0067] Among them, the first pipeline 22 is used to receive the gas returned from the humidity exchanger 3, so that the air pressure inside the water vapor balancer 2 is kept consistent with the external atmospheric pressure, preventing the water level inside the water vapor balancer 2 from rising.

[0068] The working principle of this embodiment is as follows:

[0069] The water pump 11 continuously pumps the sample water to the nozzle 21, and after being sprayed by the nozzle 21 into the interior of the water vapor balancer 2, the water vapor balancer 2 converts a part of the sample water into water vapor, and the un-converted sample water remains at the bottom. The water vapor rises above the interior of the water vapor balancer 2. The humidity exchanger 3 extracts the water vapor located above the interior of the water vapor balancer 2 through the second pipeline 23 and converts the water vapor into a sample gas stream. The sample gas stream passes through the greenhouse gas analyzer 4, and after being detected by the greenhouse gas analyzer 4, it is returned to the humidity exchanger 3, pumped back to the first pipeline 22 of the water vapor balancer 2 by the humidity exchanger 3, and pumped back into the interior of the water vapor balancer 2 through the first pipeline 22, thereby maintaining the air pressure balance of the water vapor balancer 2 and preventing the water level from rising.

[0070] In a specific embodiment, the humidity exchanger 3 is provided with an air inlet and an air outlet 31. The air inlet is connected to the second pipeline 23; a water switch 9 is arranged on the connection path between the air inlet and the second pipeline 23. The air outlet 31 is connected to one end of the first pipeline 22 through an exhaust pipe 6;

[0071] The other end of the humidity exchanger 3 is respectively connected to the first solenoid valve 7 and the second solenoid valve 8, and is connected to the greenhouse gas analyzer 4 through the first solenoid valve 7 and the second solenoid valve 8;

[0072] The water switch 9 is respectively connected to the first solenoid valve 7 and the second solenoid valve 8.

[0073] It should be noted that, in this embodiment, one end of the water switch 9 is arranged in the connection path between the air inlet and the second pipeline 23 for detecting the water flow between the second pipeline 23 and the air inlet; the other end is respectively connected to the first electromagnetic valve 7 and the second electromagnetic valve 8 for sending an electrical signal to the first electromagnetic valve 7 and the second electromagnetic valve 8 when water flow is detected. The water switch 9, also known as a water flow switch, can adopt an existing water flow switch product on the market that can detect water flow and output an electrical signal in this embodiment.

[0074] The humidity exchanger 3 and the greenhouse gas analyzer 4 are connected by pipelines. The number of pipelines is two. The first electromagnetic valve 7 and the second electromagnetic valve 8 are respectively arranged on the two pipelines for conducting and closing the pipelines. The first electromagnetic valve 7 and the second electromagnetic valve 8 are used to close the channel between the humidity exchanger 3 and the greenhouse gas analyzer 4 and connect the greenhouse gas analyzer 4 to the external environment when receiving an electrical signal.

[0075] Among them, the first electromagnetic valve 7 and the second electromagnetic valve 8 adopt two-position three-way electromagnetic valves. The two-position three-way electromagnetic valve mainly includes a valve body, a valve core, an electromagnetic coil, and a spring. Among them, the valve body is provided with one inlet and two outlets, and the valve body internally has fluid channels with different flow directions. The valve core is arranged inside the valve body and has two working positions. The movement of the valve core can change the connection state of the fluid channels inside the valve body, thereby changing the outlet connected to the inlet. The electromagnetic coil generates an electromagnetic force to drive the valve core to move, and the spring is used to reset the valve core. When the electromagnetic coil is energized, under the action of the electromagnetic force, the valve core overcomes the elastic force of the spring and moves to one of the working positions, making the inlet communicate with one of the outlets. When the electromagnetic coil is de-energized, the elastic force of the spring pushes the valve core back to the initial working position, so that the inlet is connected to the other outlet, and the fluid channels inside the electromagnetic valve are restored to the initial state.

[0076] In this embodiment, the inlet of the first electromagnetic valve 7, the inlet of the second electromagnetic valve 8 are connected to the greenhouse gas analyzer 4. One of the outlets of the first electromagnetic valve 7 and one of the outlets of the second electromagnetic valve 8 are connected to the humidity exchanger 3. The other outlets of the first electromagnetic valve 7 and the second electromagnetic valve 8 are respectively connected to the external environment. The electromagnetic coils of the first electromagnetic valve 7 and the second electromagnetic valve 8 are respectively electrically connected to the water switch 9 (not shown in the figure).

[0077] In this embodiment, by arranging the water switch 9 between the humidity exchanger 3 and the water vapor balancer 2, it can be used to prevent water from being inhaled into the greenhouse gas analyzer 4.

[0078] The working principle of this embodiment is as follows:

[0079] The water vapor in the water vapor balancer 2 is extracted to the second pipe 23, and flows to the air inlet of the humidity exchanger 3 through the second pipe 23, enters the interior of the humidity exchanger 3 from the air inlet, and is dried by the humidity exchanger 3 to obtain a sample gas flow. The humidity exchanger 3 transmits the sample gas flow to the greenhouse gas analyzer 4 through the first solenoid valve 7. After greenhouse gas analysis, the greenhouse gas concentration data is detected. Afterwards, the greenhouse gas analyzer 4 returns the sample gas flow to the humidity exchanger 3 through the second solenoid valve 8. The humidity exchanger 3 pumps the returned sample gas flow back to the first pipe 22 of the water vapor balancer 2 from the air outlet 31.

[0080] The water switch 9 is used to monitor whether there is water flowing through the pipe connecting the second pipe 23 and the humidity exchanger 3. When water flowing is detected, the water switch 9 outputs a low-level signal to the first solenoid valve 7 and the second solenoid valve 8, so that the electromagnetic coils in the first solenoid valve 7 and the second solenoid valve 8 lose power, thereby moving the valve cores of the first solenoid valve 7 and the second solenoid valve 8, so that the inlet of the first solenoid valve 7 and the second solenoid valve 8 connected to the greenhouse gas analyzer 4 is correspondingly connected to the outlet of the first solenoid valve 7 and the second solenoid valve 8 connected to the external environment, thereby closing the passage between the humidity exchanger 3 and the greenhouse gas analyzer 4, and connecting the greenhouse gas analyzer 4 to the external environment to prevent water from entering the greenhouse gas analyzer and maintain the atmospheric pressure inside the greenhouse gas analyzer 4 to avoid damage to the greenhouse gas analyzer 4. When it is a normal situation with no water flow, the water switch 9 sends a high-level signal to the first solenoid valve 7 and the second solenoid valve 8, so that the electromagnetic coils of the first solenoid valve 7 and the second solenoid valve 8 are energized, thereby making the path between the humidity exchanger 3 and the greenhouse gas analyzer 4 conductive, so that the humidity exchanger 3 can transmit the sample gas flow to the greenhouse gas analyzer 4, and after the greenhouse gas analyzer 4 detects the sample gas flow, it can return the detected sample gas flow to the humidity exchanger 3.

[0081] In a specific embodiment, the average flow rate of the sample gas flowing into the greenhouse gas analyzer can be set at 0.13 L / min in the first solenoid valve 7 and the second solenoid valve 8 .

[0082] In a specific embodiment, the length range of the exhaust pipe 6 can be determined according to actual needs, and in this embodiment, it is preferably 2 meters to 3 meters.

[0083] In a specific embodiment, an organic glass plate 25 is further included, and the organic glass plate is arranged on the top of the collecting plate 26 of the water vapor balancer 2.

[0084] It should be noted that if Figure 2As shown, a collection tray 26 is provided at the bottom of the water vapor balancer 2, and the collection tray 26 is used to collect the sample water sprayed by the nozzle 21. An acrylic disc 25 is provided at the top of the collection tray 26 to reduce the gas exchange between the water collected at the bottom of the balancer and the atmosphere, reduce the chance of gases such as CO2 in the outside air dissolving into the water, maintain the gas concentration, and make the measured carbon emission concentration only come from the sample water, rather than the outside atmosphere.

[0085] In a specific embodiment, a drain port 24 is further provided on one side of the water vapor balancer 2, and the drain port 24 is used to drain the water inside the water vapor balancer 2.

[0086] In a specific embodiment, the spraying rate of the nozzle 21 can be set to 4 L / min.

[0087] In a specific embodiment, a temperature sensor 14 and a recorder 15 are further included;

[0088] One end of the temperature sensor 14 is inserted into the interior of the water vapor balancer 2, the other end of the temperature sensor 14 is connected to the recorder 15, and the recorder 15 is arranged outside the water vapor balancer 2.

[0089] It should be noted that the temperature sensor 14 is used to measure the temperature inside the water vapor balancer 2, and the recorder 15 is used to store and display the temperature data collected by the temperature sensor 14. The tester can monitor the temperature inside the water vapor balancer 2 based on the data stored in the recorder 15, so as to correct the influence of temperature changes on the measurement.

[0090] In an example, the acquisition frequency of the temperature sensor 14 and the recorder 15 can be set according to actual needs. In this embodiment, it is preferably once every 10 minutes.

[0091] In a specific embodiment, the humidity exchanger 3 includes a water-vapor separation membrane 32 and an air pump 33;

[0092] One end of the air pump 33 is connected to the air inlet, and the other end of the air pump 33 is connected to the air outlet 31, and is used to extract water vapor;

[0093] The water-vapor separation membrane 32 is used to dry the water vapor to obtain a sample gas stream.

[0094] It should be noted that the water-vapor separation membrane 32 is arranged at the air inlet, and is used to dry the water vapor flowing in from the air inlet, so as to realize the separation of water and gas, obtain a sample gas stream, and is used to transmit the sample gas stream to the interior of the greenhouse gas analyzer 4 through the first electromagnetic valve 7.

[0095] In a specific embodiment, the flow rate of the air pump 33 can be set according to actual needs. In this embodiment, the maximum rate of the air pump 33 is preferably 1.5 L / min.

[0096] In a specific embodiment, it further includes a storage and visualization module 16. The storage and visualization module 16 is connected to the greenhouse gas analyzer 4, the power supply module 5, and the industrial router, and is used for storing and displaying greenhouse gas concentration data.

[0097] It should be noted that the storage and visualization can be used to store greenhouse gas concentration data, display greenhouse gas concentration data, realize the visualization of greenhouse gas concentration data, and facilitate researchers to carry out research. The power supply module 5 can be used to supply power to the storage and visualization module 16.

[0098] Among them, the storage and visualization module 16 can also be connected to the industrial router and connect to external devices through the industrial router, so that researchers can view greenhouse gas concentration data at the detection site and can also remotely access the storage and visualization module 16 to obtain greenhouse gas concentration data, realizing remote monitoring.

[0099] In a specific embodiment, the storage and visualization module 16 can be a laptop computer.

[0100] In a specific embodiment, the power supply module 5 includes an energy trailer 17. The energy trailer 17 is provided with a storage battery and a solar panel. The storage battery is respectively connected to an inverter and the solar panel.
