Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, specifically to a real-time multi-gas pollutant collaborative monitoring and analysis system. Background Technology

[0002] Existing real-time multi-gas pollutant monitoring equipment includes Fourier transform infrared (FTIR) gas analyzers, gas chromatography-mass spectrometry (GC-MS), tuned diode laser absorption spectroscopy (TDLAS), and non-dispersive infrared spectroscopy (NDIR). Among these, the Fourier transform infrared (FTIR) gas analyzer is a precision instrument used for continuous monitoring and analysis of gas composition. It can detect and quantify multiple gases, including but not limited to CO, CO2, SO2, NOx, CH4, NH3, HCl, HF, and various volatile organic compounds (VOCs). It plays an important role in environmental monitoring, process control, and laboratory analysis.

[0003] However, the aforementioned real-time multi-gas pollutant monitoring devices, such as Fourier transform infrared gas analyzers, are usually used in fixed locations, making it inconvenient to carry them to the site for real-time monitoring of multi-gas pollutants. Therefore, existing technologies usually require the transfer of multi-gas pollutant samples, and the transfer process may lead to inaccurate detection data for multi-gas pollutants. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a real-time multi-gas pollutant collaborative monitoring and analysis system, which solves the problem that the prior art cannot monitor multiple gas pollutants on-site in real time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A real-time multi-gas pollutant collaborative monitoring and analysis system is provided, including a housing with casters at the bottom, a real-time multi-gas pollutant monitoring device inside the housing, a gas sample flow tube on the real-time multi-gas pollutant monitoring device, an inlet of the gas sample flow tube connected to the gas outlet of a sampling pump located inside the housing, a gas inlet of the sampling pump connected to the sampling tube, one end of the sampling tube passing through the side of the housing and connected to a sampling probe, and an outlet of the sampling pump connected to an exhaust port located on the side of the housing.

[0006] The working principle of this solution is as follows: the housing, equipped with casters at the bottom, is brought to the site. The sampling pump is turned on, allowing the on-site gas to enter the sampling tube through the sampling probe. The gas is then drawn in by the sampling pump inside the housing through the gas inlet and delivered to the gas sample flow tube. The flowing gas sample undergoes component analysis inside the real-time multi-gas pollutant monitoring device, obtaining the composition data of multiple gas pollutants. Residual gas or backflushing exhaust gas is discharged from the exhaust port on the side of the housing through the gas outlet of the sampling pump and the exhaust pipe. This solution achieves portability by housing the real-time multi-gas pollutant monitoring device in a caster housing, making it easy for users to carry to different monitoring sites for real-time monitoring and analysis of multiple gas pollutants, thus improving monitoring efficiency and data accuracy.

[0007] Furthermore, the top panel of the enclosure is equipped with at least two ventilation openings, and a ventilation fan is installed at each ventilation opening. The ventilation fans are used for ventilation and cooling, effectively reducing the temperature inside the enclosure and providing a stable working environment for the real-time multi-gas pollutant monitoring equipment, thereby ensuring the accuracy of the monitoring data and the stable operation of the equipment.

[0008] Furthermore, shock-absorbing pads are installed between the real-time multi-gas pollutant monitoring equipment and the bottom plate of the enclosure. These pads reduce the impact of vibrations on the monitoring equipment during transportation, protecting it from damage, extending its service life, and also helping to improve the stability of the monitoring data.

[0009] Furthermore, the sampling probe is equipped with an internal particle filter. This particle filter removes solid particulate impurities from the gas sample, preventing contamination of the real-time multi-gas pollutant monitoring equipment.

[0010] Furthermore, a constant-temperature heating jacket is fitted over the sampling tube, and this jacket is electrically connected to a temperature controller attached to the outside of the gas sample flow tube. The temperature controller can control the temperature of the constant-temperature heating jacket, enabling it to regulate the temperature of the gas sample, thus avoiding the influence of temperature changes and gas component condensation on the gas sample and improving the accuracy of monitoring data.

[0011] Furthermore, the gas sample flow tube is also connected to a drying device, which is located inside the real-time multi-gas pollutant monitoring device and is used to dry the gas in the real-time multi-gas pollutant monitoring device and the gas sample flow tube to remove the influence of moisture on the monitoring results.

[0012] Furthermore, the real-time multi-gas pollutant monitoring device is equipped with a backflush port at the connection point with the gas sample flow tube. The backflush port is used to connect to an external nitrogen tank. The backflush port allows external nitrogen to be used to backflush the gas sample flow tube after each monitoring cycle, removing residual pollutants from the tube, keeping the monitoring system clean, and preventing cross-contamination of gas samples.

[0013] Furthermore, a power connection port and a data connection port for connecting to an external computer are provided on the side wall of the enclosure near the real-time multi-gas pollutant monitoring device. These ports facilitate power supply and data transmission for the device, improving system usability and data real-time performance.

[0014] Furthermore, the sampling tube extends 3m to 5m through the enclosure. The longer sampling tube provides greater flexibility, allowing users to sample at different monitoring points without being limited by the enclosure's location.

[0015] This utility model discloses a real-time multi-gas pollutant synergistic monitoring and analysis system, the beneficial effects of which are: This invention achieves portability by housing the real-time multi-gas pollutant monitoring device in a case equipped with casters, making it easy for users to carry to different monitoring sites for real-time monitoring and analysis of multiple gas pollutants, thereby improving monitoring efficiency and data accuracy.

[0017] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0018] refer to Figure 1 and Figure 3 This embodiment provides a real-time multi-gas pollutant collaborative monitoring and analysis system, including a housing 1 and a real-time multi-gas pollutant monitoring device 2.

[0019] The bottom of the enclosure 1 is equipped with casters 11 with brakes on all four sides for easy movement. At least two ventilation openings 14 are provided on the top plate of the enclosure 1, and a ventilation fan 15 is installed at each ventilation opening 14. The ventilation fans 15 are used for ventilation and cooling, effectively reducing the temperature inside the enclosure 1 and providing a stable working environment for the real-time multi-gas pollutant monitoring equipment 2, thereby ensuring the accuracy of monitoring data and the stable operation of the equipment.

[0020] refer to Figure 2 The real-time multi-gas pollutant monitoring device 2 is fixed inside the housing 1, and a shock-absorbing pad 9 is installed between the real-time multi-gas pollutant monitoring device 2 and the bottom plate of the housing 1. The shock-absorbing pad 9 can be made of highly elastic materials such as rubber and polyurethane. By setting the weight-reducing pad 9 made of highly elastic material, the deformation of the elastic material can absorb and buffer the vibration energy generated during transportation, thereby reducing the vibration impact on the real-time multi-gas pollutant monitoring device 2 during transportation, protecting the equipment from damage, and extending the service life of the equipment. In addition, the damping characteristics and structural deformation of the elastic material itself can effectively isolate the impact and vibration from the bottom of the housing, thereby ensuring the stability and accuracy of the monitoring data.

[0021] The real-time multi-gas pollutant monitoring device 2 is equipped with a gas sample flow tube 3. The inlet of the gas sample flow tube 3 is connected to the gas outlet 62 of the sampling pump 6 located inside the housing 1. The gas inlet 63 of the sampling pump 6 is connected to the sampling tube 4. One end of the sampling tube 4 passes through the side of the housing 1 and is connected to the sampling probe 5. The outlet 64 of the sampling pump 6 is connected to the exhaust port located on the side of the housing 1.

[0022] A power connection port 12 and a data connection port 13 for connecting to an external computer are provided on the side wall of the enclosure 1 near the real-time multi-gas pollutant monitoring device 2. The power connection port 12 and the data connection port 13 on the enclosure 1 facilitate the user's power supply and data transmission for the real-time multi-gas pollutant monitoring device 2, improving the ease of use of the system and the real-time performance of the data.

[0023] In this embodiment, the sampling tube 4 extends 3m to 5m through the housing 1. The longer sampling tube 4 provides greater flexibility, allowing users to sample at different monitoring points without being limited by the location of the housing 1. The real-time multi-gas pollutant monitoring device 2 is preferably a Fourier transform infrared gas analyzer, such as the infrared matrix-MG5. This embodiment achieves portability by housing the real-time multi-gas pollutant monitoring device 2 within the housing 1 equipped with casters 11, facilitating its transport to different monitoring sites for real-time monitoring and analysis of multiple gas pollutants, thus improving monitoring efficiency and data accuracy.

[0024] To prevent contamination of the real-time multi-gas pollutant monitoring device 2, a particle filter is installed inside the sampling probe 5. The particle filter can remove solid particulate impurities from the gas sample, and a dryer can be added to the particle filter depending on the sampling environment.

[0025] To avoid the effects of temperature and gas component condensation, a constant-temperature heating jacket is fitted over the sampling tube 4. This heating jacket is electrically connected to a temperature controller 7, which is attached to the outside of the gas sample flow tube 3. The temperature controller 7 controls the temperature of the heating jacket, allowing it to regulate the temperature of the gas sample and improve the accuracy of the monitoring data. In this embodiment, the heating jacket and temperature controller 7 are a matching set, and their model can be ZNHW-200.

[0026] To remove the influence of moisture on the monitoring results, the gas sample flow tube 3 is also connected to a drying device 8. The drying device 8 is located inside the real-time multi-gas pollutant monitoring device 2 and is used to dry the gas in both the real-time multi-gas pollutant monitoring device 2 and the gas sample flow tube 3. The drying device 8 can dry the gas sample in the gas sample flow tube 3. In this embodiment, the drying device 8 can be a silica gel dryer, a molecular sieve dryer, or a small heatless regenerative dryer.

[0027] To avoid cross-contamination, a backflush port 21 is provided at the connection point between the real-time multi-gas pollutant monitoring device 2 and the gas sample flow tube 3. The backflush port 21 is used to connect with an external nitrogen tank. A one-way valve is installed inside the backflush port 21, which can use external nitrogen to backflush the gas sample flow tube 3 after each monitoring to remove residual pollutants in the tube and keep the monitoring system clean.

[0028] In summary, the working principle of this solution is as follows: Bring the housing 1, equipped with casters 11 at the bottom, into the site. Turn on the temperature controller 7 to adjust the constant temperature heating jacket to heat the sampling tube 4. Then turn on the sampling pump 6. After turning on, the sampling pump 6 can create negative pressure to extract external gas samples. The gas sample is first collected by the sampling probe 5 and drawn into the gas inlet 63 of the sampling pump 6 through the sampling tube 4. Subsequently, the gas sample is discharged from its gas outlet 62 under the drive of the sampling pump 6 and enters the inlet of the gas sample flow tube 6. It is then transported to the real-time multi-gas pollutant monitoring device 2 for real-time component analysis to obtain the component data of multi-gas pollutants. After the monitoring is completed, open the housing 1 and connect the backflush port 21 to the external nitrogen tank for backflush to remove the pollutants remaining in the tube. The gas that has been analyzed or the gas used for backflush is discharged from the gas outlet 64 of the pump 6 through the exhaust port on the side of the housing.

[0029] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
