Description

Technical Field

[0001] This invention relates to the field of air pollution monitoring technology, and in particular to a portable detection and analysis device for total particulate matter from stationary pollution sources. Background Technology

[0002] Stationary source particulate matter should include both filterable and coagulateable particulate matter. Existing stationary source particulate matter testing methods can only measure filterable particulate matter and cannot measure coagulateable particulate matter. Coagulateable particulate matter needs to be measured separately. That is, in the existing total particulate matter testing methods, filterable particulate matter and coagulateable particulate matter need to be tested separately and then the total particulate matter concentration is calculated.

[0003] Currently, my country's control over filterable particulate matter is relatively effective, but coagulable particulate matter (CPM) is not included in the regulatory system due to the lack of emission standards and simple testing methods, resulting in a concerning situation. Existing total particulate matter (TPM) testing equipment suffers from low integration and insufficient portability, requiring two sets of monitoring equipment for sampling. Even with the EPA M202 standard, equipment portability remains inadequate. Furthermore, on-site operation is cumbersome, requiring on-site solution preparation, processing and collection after sampling, and multiple cleanings of the absorption bottles, leading to lengthy preparation and operation times. In addition, significant systematic errors are inherent; using different equipment inevitably introduces systematic errors due to equipment differences, making subsequent analysis highly complex, time-consuming, and prone to human error.

Detailed Implementation

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1-2 As shown in some illustrative embodiments, a portable detection and analysis device for total particulate matter from a stationary pollution source is provided, comprising: a sampling gun 100, an FPM detection device 200, a pretreatment device 300, a CPM detection device 400, and a sampling device 500 arranged sequentially according to the flue gas flow direction.

[0018] The FPM detection device 200 is used to test filterable particulate matter, and the CPM detection device 400 is used to test condensable particulate matter. Flue gas enters the detection and analysis equipment of this application through the sampling gun 100. The FPM detection device 200 captures and measures filterable particulate matter, then enters the pretreatment device 300 to cool the flue gas to approximately 30°C while storing condensate. The flue gas continues to flow into the CPM detection device 400 to capture and measure condensable particulate matter. The sampling device 500 dries and measures the flue gas and provides the power for its flow.

[0019] The sampling gun 100 is used to extract flue gas samples from the exhaust gas conveying pipe 500 and send them to the subsequent processing device. Specifically, it includes: sampling nozzle 1, Pitot tube 2, flue gas temperature sensor 3, sampling tube 4, heating and insulation sleeve 5, and temperature controller 6.

[0020] Sampling nozzle 1 is located at the front end of sampling gun 100. Its function is to ensure that the velocity of the flue gas entering sampling gun 100 is consistent with the actual flow velocity inside exhaust gas conveying pipe 600, i.e., to achieve isokinetic sampling. Pitot tube 2 calculates the flue gas velocity in real time by measuring the difference between the total pressure and static pressure of the flue gas flow in exhaust gas conveying pipe 600. Flue gas temperature sensor 3 can be a platinum resistance thermometer or a thermocouple, used to measure the real-time temperature of the flue gas inside exhaust gas conveying pipe 600. Installation method: Sampling nozzle 1, Pitot tube 2, and flue gas temperature sensor 3 are integrated on a flange or fixing block, and extend together into the exhaust gas conveying pipe 600 through a standardized through-slot opened on the exhaust gas conveying pipe 600, ensuring that the measurement point and sampling point are consistent and the data is synchronized.

[0021] One end of the sampling tube 4 is connected to the sampling nozzle 1, and the other end of the sampling tube 4 is connected to the FPM heating and sealing mechanism 7 in the FPM detection device 200. A heating and insulation sleeve 5 is installed on the outer wall of the sampling tube 4. A temperature controller 6 is connected to the heating and insulation sleeve 5. The heating and insulation sleeve 5 can be a sleeve structure composed of an electric heating element and insulation material. The temperature controller 6 acquires the measurement data from the temperature sensor inside the heating and insulation sleeve 5 and controls the heating power of the electric heating element to stabilize the inner wall temperature of the sampling tube 4 at a set value.

[0022] The working process of sampling gun 100: The flue gas is first drawn at a constant speed through sampling nozzle 1, and then enters sampling tube 4 which is wrapped by heating and heat preservation sleeve 5; under the control of temperature controller 6, the temperature of flue gas in sampling tube 4 is heated to about 120°C to ensure that the moisture and condensable substances in the flue gas always remain in a gaseous state and no condensate is released; finally, the flue gas after high-temperature heating is transported to FPM heating and sealing mechanism 7 in FPM detection device 200.

[0023] The FPM detection device 200 receives high-temperature flue gas from the sampling gun 100 for testing filterable particulate matter. Specifically, it includes: an FPM heating and sealing mechanism 7, an FPM beta-ray source 8, an FPM ray detector 9, an FPM detection paper tape 10, and an FPM paper tape conveying control mechanism 11.

[0024] Among them, the heating and sealing mechanism of the FPM detection device 200 is the FPM heating and sealing mechanism 7; the β-ray detector of the FPM detection device 200 includes: FPM β-ray source 8 and FPM ray detector 9.

[0025] The two ends of the FPM detection paper tape 10 are connected to the FPM paper tape conveying control mechanism 11. The FPM paper tape conveying control mechanism 11 includes: a drive roller 201, a driven roller 202, a motor 203, and a guide wheel 204. The power output shaft of the motor 203 is connected to the drive roller 201. The two ends of the FPM detection paper tape 10 are respectively wound around the drive roller 201 and the driven roller 202. The guide wheel 204 is used to turn the FPM detection paper tape 10. When the motor 203 starts, it drives the drive roller 201 to rotate, causing the tape body of the FPM detection paper tape 10 to move, thereby moving the tape body portion located within the FPM heating and sealing mechanism 7 between the FPM beta ray source 8 and the FPM ray detector 9 for measurement.

[0026] The FPM heating and sealing mechanism 7 is arranged in parallel with the β-ray detector. The body of the FPM detection paper tape 10 is located in the FPM heating and sealing mechanism 7 and in the β-ray detector. That is, part of the body of the FPM detection paper tape 10 is located in the FPM heating and sealing mechanism 7 and part of the body of the FPM detection paper tape 10 is located in the β-ray detector, specifically between the FPM β-ray source 8 and the FPM ray detector 9.

[0027] The FPM paper tape conveying control mechanism 11 is connected to the FPM detection paper tape 10 to drive the tape body of the FPM detection paper tape 10 to move between the FPM heating and sealing mechanism 7 and the β-ray detector. When the flue gas enters the FPM detection device 200 from the sampling gun 100, it enters the FPM heating and sealing mechanism 7, where the filterable particulate matter in the flue gas is captured by the FPM detection paper tape 10. Then, the FPM paper tape conveying control mechanism 11 is activated, causing the portion of the tape body that has captured the filterable particulate matter to move into the β-ray detector. The FPM β-ray source 8 generates β-rays, which penetrate the FPM detection paper tape 10. Some of the rays are absorbed by the FPM detection paper tape 10 and the particulate matter on it, reducing the intensity of the rays received by the FPM ray detector 9. The increased mass of particulate matter on the FPM detection paper tape 10 is calculated according to the β-ray attenuation law.

[0028] The pretreatment unit 300 receives flue gas from the FPM detection unit 200 and performs temperature-controlled condensation, separation, and temporary storage of condensate to facilitate subsequent CPM collection and analysis. Specifically, it includes: a condenser tube 12, a semiconductor cooler 13, a condensate storage device 14, a metering peristaltic pump 16, a condensate drain pipe 17, and a condensate dripping pipe 18.

[0029] The inlet side of the condenser pipe 12 is connected to the FPM heating and sealing mechanism 7, the outlet side of the condenser pipe 12 is connected to the condensate storage device 14, and the condensate storage device 14 is connected to the CPM heating and sealing mechanism 19.

[0030] Flue gas from sampling gun 100 first enters condenser tube 12. A semiconductor cooler 13 is mounted on the outer wall of condenser tube 12. Upon energization, it generates a cooling effect, rapidly and precisely controlling the flue gas temperature within condenser tube 12 to approximately 30°C, meeting the requirements of EPA Method 202. The condenser tube 12 must be of sufficient length, employing a spiral or coil structure. This not only extends the contact time between the high-temperature flue gas and the low-temperature tube wall, ensuring sufficient heat exchange and condensation, but also achieves efficient cooling within a compact space, significantly reducing the overall size and weight of the cooling module and facilitating equipment portability.

[0031] The condensate formed in the condenser tube 12 and the cooled flue gas enter the condensate storage device 14 together. Due to gravity, the denser condensate settles to the bottom of the device, while the flue gas flows out from the upper part of the device. The upper part of the condensate storage device 14 is connected to the CPM heating and sealing mechanism 19 of the CPM detection device 400 through the flue gas passage 301, and the lower part of the condensate storage device 14 is connected to the CPM heating and sealing mechanism 19 through the condensate dripping pipe 18. The metering peristaltic pump 16 is installed on the condensate dripping pipe 18.

[0032] The condensate drain pipe 17 is connected to the condensate dripping pipe 18, and the bottom of the condensate storage device 14 is provided with a condensate drain port 15 to facilitate thorough drainage and cleaning after sampling.

[0033] The condensate formed after cooling by the condenser tube 12 is temporarily stored in the condensate storage device 14. The flue gas continues to pass through the flue gas path 301 and is captured by the CPM detection paper tape 22 of the CPM detection device 400. After sampling for a certain period of time, sampling is stopped, and the sampling device 500 records the sampling volume and duration, while simultaneously acquiring the condensate volume recorded by the sampling personnel in the condensate storage device 14. Then, the quantitative peristaltic pump 16 is started to extract the condensate, which is dripped into the CPM detection paper tape 22 through the condensate dripping pipe 18.

[0034] The CPM detection device 400 receives flue gas from the pretreatment device 300 for testing condensable particulate matter, and specifically includes: a CPM heating and sealing mechanism 19, a CPM beta-ray source 20, a CPM ray detector 21, a CPM detection paper tape 22, and a CPM paper tape conveying control mechanism 23.

[0035] Among them, the heating and sealing mechanism of the CPM detection device 400 is the CPM heating and sealing mechanism 19; the β-ray detector of the CPM detection device 400 includes: CPM β-ray source 20 and CPM ray detector 21.

[0036] Both ends of the CPM detection paper tape 22 are connected to the CPM paper tape conveying control mechanism 23. The CPM paper tape conveying control mechanism 23 has the same structure as the FPM paper tape conveying control mechanism 11, specifically including: an active winding roller 201, a driven winding roller 202, a motor 203, and a guide wheel 204. The power output shaft of the motor 203 is connected to the active winding roller 201. The two ends of the CPM detection paper tape 22 are respectively wound around the active winding roller 201 and the driven winding roller 202. The guide wheel 204 is used to turn the CPM detection paper tape 22. When the motor 203 starts, it drives the active winding roller 201 to rotate, causing the tape body of the CPM detection paper tape 22 to move, thereby causing the tape body located in the CPM heating and sealing mechanism 19 to move between the CPM beta ray source 20 and the CPM ray detector 21 for measurement.

[0037] The CPM heating and sealing mechanism 19 is arranged in parallel with the β-ray detector. The body of the CPM detection paper tape 22 is located in both the CPM heating and sealing mechanism 19 and the β-ray detector. Specifically, part of the body of the CPM detection paper tape 22 is located in the CPM heating and sealing mechanism 19 and part of the body of the CPM detection paper tape 22 is located in the β-ray detector, specifically between the CPM β-ray source 20 and the CPM ray detector 21.

[0038] The CPM paper tape conveying control mechanism 23 is connected to the CPM detection paper tape 22 to drive the tape body of the CPM detection paper tape 22 to move between the CPM heating and sealing mechanism 19 and the β-ray detector. When the flue gas enters the CPM detection device 400 from the pretreatment device 300, it enters the CPM heating and sealing mechanism 19, where condensable particulate matter is captured by the CPM detection paper tape 22. Then, the CPM paper tape conveying control mechanism 23 is activated, causing the portion of the tape containing condensable particulate matter to move into the β-ray detector. The CPM β-ray source 20 generates β-rays, which penetrate the CPM detection paper tape 22. Some of the rays are absorbed by the CPM detection paper tape 22 and the condensable particulate matter on it, reducing the intensity of the rays received by the CPM ray detector 21. The increased mass of condensable particulate matter on the CPM detection paper tape 22 is calculated according to the β-ray attenuation law.

[0039] The FPM heating sealing mechanism 7 has the same structure as the CPM heating sealing mechanism 19, specifically including: a housing 401 and an input interface 402 and an output interface 403 disposed on the housing 401.

[0040] The input interface 402 of the FPM heating and sealing mechanism 7 is connected to the sampling tube 4, and the output interface 403 of the FPM heating and sealing mechanism 7 is connected to the condenser tube 12. The input interface 402 of the CPM heating and sealing mechanism 19 is connected to the condensate dripping pipe 18 and the flue gas passage 301, and the output interface 403 is connected to the sampling device 500. A through slot 404 is provided on the outer casing 401 so that the FPM detection paper tape 10 or the CPM detection paper tape 22 can pass through the through slot 404, thereby allowing part of the detection paper tape to be located in the cavity inside the outer casing 401. When the flue gas enters the FPM heating and sealing mechanism 7 through the input interface 402, it passes through the body of the FPM detection paper tape 10 and is then discharged through the output interface 403.

[0041] The CPM heating sealing mechanism 19 has a heating element, such as a cylindrical heater or a small PTC heating element, installed inside the outer shell 401 to achieve local heating. At the same time, a thermocouple or thermistor is embedded near the heating area to monitor and control the heating temperature.

[0042] The two-step capture workflow is as follows: Step 1: Capturing gaseous CPM: After passing through the pretreatment device 300, the flue gas enters the CPM heating and sealing mechanism 19 through the flue gas path 301. At this time, the heating element in the CPM heating and sealing mechanism 19 is not activated, and the flue gas flows directly through the CPM detection paper tape 22. During the cooling process, the condensable particulate matter in the flue gas in the gaseous state undergoes homogeneous nucleation on the surface of the CPM detection paper tape 22 and is captured, forming the first part of CPM.

[0043] Step 2: Capturing Dissolved CPM: After the gaseous CPM is captured, the flue gas extraction is paused, and the quantitative peristaltic pump 16 is started to add condensate from the condensate storage device 14 onto the CPM detection paper strip 22. Then, the CPM heating and sealing mechanism 19 and the sampling pump 26 in the sampling device 500 are started in coordination. That is, the heating element in the CPM heating and sealing mechanism 19 heats and evaporates the condensate on the CPM detection paper strip 22. The water vapor formed is extracted by the sampling pump 26. As the water evaporates, the second part of CPM that was originally dissolved in the condensate precipitates out and is uniformly deposited on the CPM detection paper strip 22.

[0044] After completing the above two collection steps, the CPM detection paper tape 22 has collected all the CPM in the flue gas. Then, the CPM paper tape conveying control mechanism 23 is activated, causing the portion of the tape containing condensable particles to move into the β-ray detector. The increase in particulate matter mass on the CPM detection paper tape 22 is calculated according to the β-ray attenuation law. Combining the sampling volume and sampling time recorded by the sampling device 400 with the condensate volume entered by the operator, the device's control system calculates the final CPM concentration, final FPM concentration, and total particulate matter concentration in the flue gas, achieving rapid on-site detection.

[0045] The two-step collection method ensures that both gaseous CPM in the flue gas and CPM dissolved in the condensate are completely collected on the same detection strip, avoiding sample loss, transfer errors, and computational complexity that may occur with traditional methods that separately process the filter membrane and absorbent, thus ensuring the accuracy of the measurement results. Furthermore, this structure allows for simultaneous sampling and analysis; the next sample can be collected and analyzed immediately after the first sample is collected.

[0046] The sampling device 500 includes a drying device 24, a metering device 25, and a sampling pump 26. The drying device 24 is connected to the CPM heating and sealing mechanism 19, the metering device 25 is connected to the drying device 24, and the sampling pump 26 is connected to the metering device 25.

[0047] After passing through the CPM detection device 400, the gas enters the sampling device 500. The gas first passes through a drying device 24, which contains a desiccant, such as anhydrous magnesium perchlorate. Residual water vapor in the gas is absorbed by the desiccant, resulting in pure dry flue gas. Subsequently, the dry flue gas flows through a metering device 25, which includes a flow meter and a timer. The gas volume is measured and recorded in real time, along with the sampling duration. Finally, the gas is extracted and vented by the sampling pump 26.

[0048] The portable detection and analysis device for total particulate matter from stationary pollution sources provided by this invention has the following advantages compared with the prior art: Integrating β-ray attenuation analysis technology into portable devices creates an integrated sampling and analysis unit, enabling rapid detection of both condensable and filterable particulate matter and improving detection efficiency. The two-step collection method implemented by the CPM detection device 400 quantitatively collects and enriches gaseous and condensable particulate matter dissolved in condensate in the same medium, ensuring the integrity of sample collection and guaranteeing the accuracy and reliability of monitoring data. Through modular design, traditionally dispersed equipment is highly integrated into one compact structure, making it easy to carry and significantly reducing operational complexity and human error. Compared with traditional manual monitoring methods, this invention improves on-site sampling speed and enhances on-site operational efficiency. It achieves simultaneous monitoring of FPM and CPM, the test is simple, and multiple parallel samples can be monitored by moving the paper tape during the test, thus improving the monitoring efficiency.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
