Description

Technical Field

[0001] This application relates to the field of waste gas pollutant sampling technology, and more specifically, to an absorption bottle sampling device. Background Technology

[0002] With increasing environmental awareness, people are paying more and more attention to the monitoring and detection of various waste gas emissions. Ammonia is a colorless gas with a strong, pungent odor; its molecular formula is NH3. Excessive ammonia levels can be harmful to the human body, causing strong irritation to the respiratory tract, skin, and eyes, and may lead to upper respiratory tract infections and chronic poisoning.

[0003] In current integrated collection systems for various forms of ammonia from stationary pollution sources, it is often necessary to disassemble the absorption bottle. However, due to design flaws, the pre-tightening force between the absorption bottle and the sampling nozzle cannot be guaranteed, which affects the sampling results. Utility Model Content

[0004] The purpose of this application is to provide an absorption bottle sampling device that enables the absorption bottle to be easily disassembled and replaced, ensures a tight fit between the absorption bottle nozzle and the pipeline nozzle after installation, achieves a tight seal at the ground joint of the absorption bottle, and has a simple and efficient structure.

[0005] At the same time, simultaneous sampling of smoke and flue gas is also considered to avoid backflow of the absorbent liquid caused by manual switching of different sampling equipment, which would affect the true value of the sample.

[0006] In a first aspect, embodiments of this application provide an absorption bottle sampling device, comprising: a probe assembly for collecting mixed emissions of waste gas; and a sampling assembly comprising a second sampling structure, a first sampling structure, and a co-sampling device, wherein the second sampling structure is connected to the probe assembly and the co-sampling device, the first sampling structure is connected to the probe assembly and the co-sampling device, and the waste gas flow rate of the first sampling structure is less than the waste gas flow rate of the second sampling structure.

[0007] In the above process, the second sampling structure and the first sampling structure are respectively connected to the probe assembly. When the sampling equipment is working, the mixed exhaust gas enters the probe assembly. The second sampling structure is a high-flow-rate channel, and the first sampling structure is a low-flow-rate channel. Under the action of the probe assembly, the second sampling structure can sample the dust in the exhaust gas, and the first sampling structure can sample the flue gas. This device can simultaneously sample dust and flue gas, avoiding backflow of the absorbent liquid caused by manually changing different sampling equipment, which would affect the true value of the sample.

[0008] In some embodiments, the second sampling structure includes a second sampling nozzle and a second sampling tube, the second sampling nozzle being connected to the probe assembly, and the second sampling tube being connected to both the second sampling nozzle and the simultaneous sampling device.

[0009] In the above process, the second sampling nozzle is connected to the sampling equipment through the second sampling tube, which can complete high-flow sampling, realize the separate sampling of ammonia and ammonium salt, avoid the loss of ammonia and ammonium salt in the front-end pipeline under low flow, simplify the process, and ensure the accuracy of sampling.

[0010] In some embodiments, the first sampling structure includes a first sampling nozzle, an absorption mechanism, and a first sampling tube, wherein the first sampling nozzle is connected to the absorption mechanism, and the first sampling tube is connected to both the absorption mechanism and the simultaneous sampling device.

[0011] In the above process, the absorption mechanism is connected to the sampling equipment through the first sampling tube to complete the diversion sampling of ammonia and ammonium salt, realize high flow rate sampling, avoid the loss of ammonia and ammonium salt in the front pipeline due to low flow rate, and then divert and sample ammonia gas at a low flow rate to improve the sampling accuracy of ammonia and avoid the backflow of absorption liquid.

[0012] In some embodiments, the absorption mechanism includes a plurality of absorption bottles and a temperature regulating component, wherein the plurality of absorption bottles are connected in series, and the temperature regulating component is disposed on the outside of the absorption bottles for regulating the temperature of the absorption bottles.

[0013] In the above process, a small amount of waste gas enters the absorption bottle and is absorbed by the absorbent liquid inside. Setting up multiple absorption bottles ensures that the collected samples are representative and avoids cross-contamination. During the sampling process, using multiple absorption bottles ensures that the absorbent liquid in each bottle can independently absorb pollutants in the atmosphere. This prevents the absorbent liquid in one bottle from affecting the sampling effect of another bottle due to excessively high concentration, thereby ensuring the accuracy and reliability of the sampling results.

[0014] In some embodiments, the temperature control component includes an ice box and a water bath, the ice box being configured to house a portion of the absorption bottle structure, and the water bath being configured to house another portion of the absorption bottle structure.

[0015] In the above process, the ice box and water bath are used to adjust the temperature of the absorption bottle. In actual sampling, a certain temperature and concentration of the absorption liquid can be maintained, which can reduce the volatilization of ammonia, increase the solubility of ammonia in the absorption liquid, reduce the chance of it escaping from the absorption liquid, and ensure the accuracy of the sampling results.

[0016] In some embodiments, the first sampling structure further includes an elastic mechanism connected to the absorption bottle for adjusting the pre-tightening force between the absorption bottle and the first sampling nozzle.

[0017] In the above process, the absorption bottle is connected to an elastic mechanism, which ensures that the sampling bottle is always in close contact with the first sampling nozzle during sampling, thus ensuring a tight seal. At the same time, it is very convenient to remove the sampling bottle from the first sampling nozzle after sampling, which improves flexibility and makes operation easier.

[0018] In some embodiments, the first sampling structure further includes an elastic mechanism and a guiding mechanism, both of which are connected to the absorption bottle. The elastic mechanism is used to adjust the pre-tightening force between the absorption bottle and the first sampling nozzle.

[0019] In the above process, the absorption bottle is connected to an elastic mechanism and a guiding mechanism, which allows the absorption bottle to move along the guiding mechanism under the action of the elastic mechanism. This ensures that the absorption bottle is always in close contact with the first sampling nozzle during sampling, thus guaranteeing a tight seal. At the same time, it is very convenient to remove the sampling bottle from the first sampling nozzle after sampling, improving flexibility and making the operation easy.

[0020] In some embodiments, the probe assembly includes a first probe, a second probe, a sampling filter cartridge, and a sampling filter membrane. One end of the first probe is connected to the sampling filter cartridge, and the sampling filter membrane is connected between the first probe and the second probe. The second probe is connected to the second sampling structure and the first sampling structure, respectively.

[0021] In the above implementation process, the probe assembly is equipped with a sampling filter cartridge and a sampling filter membrane. When the sampling equipment is working, ammonium salt sampling can be performed by either the sampling filter cartridge or the sampling filter membrane in the high-flow-rate channel. The combination is flexible and diverse, meeting the needs of many environmental monitoring scenarios.

[0022] In some embodiments, the absorption bottle sampling device further includes a first temperature control component, the first temperature control component being configured as a first temperature control chamber, the first temperature control chamber being configured to accommodate at least a portion of the structure of the first probe and the sampling filter cartridge.

[0023] In the above process, the first temperature control component can control the temperature of the first probe and the sampling filter cartridge, reduce low temperature loss, avoid being affected by the temperature inside the chimney, realize individual temperature control according to the actual situation of the flue, and improve sampling reliability.

[0024] In some embodiments, the absorption bottle sampling device further includes a second temperature control component, wherein the control temperature of the first temperature control component is consistent with the control temperature of the second temperature control component, and the second temperature control component is configured to accommodate the second probe and the sampling filter membrane.

[0025] In the above process, the first temperature control component and the second temperature control component control the temperature of different positions of the probe assembly, so that the probe assembly is always maintained at the specified temperature, reducing low temperature loss and ensuring sampling accuracy.

[0038] Atmospheric sampling is the process of collecting samples of pollutants or polluted air from the atmosphere. There are two main types of on-site sampling methods: one involves passing a large volume of air through a liquid or solid absorbent to concentrate pollutants at lower concentrations, such as the air extraction method or membrane filtration method. The other method involves collecting air containing pollutants using containers (glass bottles, plastic bags, etc.). The former measures the average concentration of pollutants in the atmosphere over a sampling period; the latter measures the instantaneous concentration or the average concentration over a short period. The sampling method should be determined based on the purpose of sampling and the site conditions. The samples should be representative. Sampling efficiency should be high, the operation should be simple, and it should facilitate subsequent analysis and measurement to obtain reliable basic data on air pollution. The purpose is to collect samples of pollutants or polluted air from the atmosphere to obtain basic data on air pollution.

[0039] Atmospheric sampling is a crucial step in atmospheric environmental monitoring, significantly impacting the reliability of monitoring data. There are two main methods for collecting atmospheric samples: one involves passing a large volume of air through a liquid absorbent or solid adsorbent to absorb or retain pollutants, thus concentrating pollutants that were initially at low concentrations in the atmosphere. Examples include the air extraction method and the membrane filtration method. The result obtained using this method is the average concentration of pollutants in the atmosphere over the sampling period. The other method involves collecting air containing pollutants using containers (glass bottles, plastic bags, rubber bulbs, syringes, etc.). This method is suitable for situations where the concentration of pollutants in the atmosphere is high; or where the measurement method has high sensitivity; or for pollutant gases and vapors that are not easily absorbed by liquid absorbents or adsorbed by solid adsorbents. The result obtained using this method is the instantaneous concentration or the average concentration of pollutants in the atmosphere over a short period.

[0040] In this application, as Figures 1-3 As shown, in a first aspect, embodiments of this application provide an absorption bottle sampling device, including: a probe assembly for collecting mixed emissions of waste gas; and a sampling assembly including a second sampling structure, a first sampling structure, and a co-sampling device 29, wherein the second sampling structure is connected to the probe assembly and the co-sampling device 29, the first sampling structure is connected to the probe assembly and the co-sampling device 29, and the waste gas flow rate of the first sampling structure is less than the waste gas flow rate of the second sampling structure.

[0041] For example, one end of the probe assembly is placed inside the chimney to collect the exhaust gas inside the chimney. The exhaust gas contains ammonia and ammonium salts. Therefore, in the second sampling structure of the high-flow-rate channel, ammonium salts are sampled. In the first sampling structure of the low-flow-rate channel, a small amount of sample gas can be extracted from the high-flow-rate exhaust gas for sampling, so as to achieve simultaneous and accurate sampling of ammonia and ammonium salts.

[0042] In the above process, the second sampling structure and the first sampling structure are respectively connected to the probe assembly. When the sampling equipment 29 is working, the mixed exhaust gas enters the probe assembly. The second sampling structure is a high-flow-rate channel, and the first sampling structure is a low-flow-rate channel. Under the action of the probe assembly, the second sampling structure can sample the dust in the exhaust gas, and the first sampling structure can sample the flue gas. It can simultaneously sample dust and flue gas, avoiding the backflow of the absorbent liquid (weak acid or weak alkaline) due to manual replacement of different sampling equipment, which would affect the true value of the sample.

[0043] Ammonia and ammonium salts in the exhaust gas from stationary pollution sources are sampled by a heated dual-channel diversion sampling gun. The front end uses a sampling filter cartridge 12 to trap particulate matter, while the rear end uses an absorption bottle 23 containing dilute phosphoric acid to collect the flue gas, achieving simultaneous collection of particulate matter and flue gas. The absorption liquid extracts the ammonium salts in the sampling filter cartridge 12, and the filter cartridge extract and flue gas absorption liquid are injected into an ion chromatograph for separation and detection. Qualitative analysis is performed based on retention time, and quantitative analysis is performed based on peak area and peak height.

[0044] like Figure 1 As shown, the second sampling structure includes a second sampling nozzle 20 and a second sampling tube 21. The second sampling nozzle 20 is connected to the probe assembly, and the second sampling tube 21 is connected to both the second sampling nozzle 20 and the simultaneous sampling device 29. For example, the probe assembly is configured with a first outlet and a second outlet, with the first outlet located above the second outlet. The second sampling nozzle 20 is connected to the first outlet, and the first sampling structure is connected to the second outlet, so that the exhaust gas discharged from the probe assembly can first enter the second sampling nozzle 20.

[0045] In the above process, the second sampling nozzle 20 is connected to the sampling device 29 through the second sampling tube 21, which can complete high-flow sampling, realize the separate sampling of ammonia and ammonium salt, avoid the loss of ammonia and sodium salt in the front-end pipeline under low flow, simplify the process, and ensure the accuracy of sampling.

[0046] Please refer to again Figure 1 The first sampling structure includes a first sampling nozzle 22, an absorption mechanism, and a first sampling tube 26. The first sampling nozzle 22 is connected to the absorption mechanism, and the first sampling tube 26 is connected to both the absorption mechanism and the sampling device 29. For example, the flow rate of the first sampling nozzle 22 is less than the flow rate of the second sampling nozzle 20, and a small amount of waste gas extracted from a large flow of waste gas passes sequentially through the first sampling nozzle 22, the absorption mechanism, and the first sampling tube 26.

[0047] In the above process, the absorption mechanism is connected to the sampling device 29 through the first sampling tube 26 to complete the diversion sampling of ammonia and ammonium salt, realize high flow rate sampling, avoid the loss of ammonia and ammonium salt in the front pipeline under low flow rate, and then divert the flow rate to sample ammonia gas, improve the sampling accuracy of ammonia, and avoid the backflow of absorption liquid.

[0048] like Figures 1-3 As shown, the absorption mechanism includes a plurality of absorption bottles 23 and a temperature regulating component. The plurality of absorption bottles 23 are connected in series, and the temperature regulating component is disposed on the outside of the absorption bottles 23 for regulating the temperature of the absorption bottles 23.

[0049] For example, the absorption bottle 23 is a glass container used for collecting pollutants using solution absorption. To collect a specific pollutant, a solution of that specific component is placed in the absorption bottle 23. When gas passes through the absorbent, the pollutant is absorbed, and its concentration can be determined through analysis. The most important performance indicators of the absorption bottle 23 are its optimal sampling flow rate, absorption efficiency, and resistance drop under conditions where a certain amount of absorbent is filled. Commonly used absorption bottles 23 have different structural forms, such as porous glass plate absorption, bubble absorption, and impact absorption.

[0050] The number of absorption bottles 23 includes, but is not limited to, two. One absorption bottle 23 is used to connect to the second outlet, while the other absorption bottle 23 is used to connect to the absorption bottle 23, realizing the series connection between the two absorption bottles 23. Thus, the exhaust gas can pass through the two absorption bottles 23 in sequence, ensuring that the collected sample is representative. Of course, in other embodiments, the number of absorption bottles 23 can also be three, four, etc., and no specific limitation is made here.

[0051] In the above process, a small amount of waste gas enters the absorption bottle 23 and is absorbed by the absorbent liquid inside the absorption bottle 23. Setting up multiple absorption bottles 23 can ensure that the collected samples are representative and can avoid cross-contamination. During the sampling process, using multiple absorption bottles 23 can ensure that the absorbent liquid in each bottle can independently absorb pollutants in the atmosphere. This can prevent the absorbent liquid in one bottle from affecting the sampling effect of another bottle due to excessively high concentration, thereby ensuring the accuracy and reliability of the sampling results.

[0052] In some embodiments, the temperature control component includes an ice box 24 and a water bath 25. The ice box 24 is configured to house a portion of the absorption bottle 23. The ice water in the ice box 24 can lower the temperature inside the absorption bottle 23, thereby increasing the solubility of ammonia in the liquid and reducing its chance of escaping from the liquid. In addition, the cold water can also help maintain the stability and effectiveness of the absorbent liquid inside the absorption bottle 23. The water bath 25 is configured to house another portion of the absorption bottle 23. For example, the ice box 24 is located above the water bath 25, and several absorption bottles 23 are located inside the ice box 24 and the water bath 25.

[0053] In the above process, the ice box 24 and the water bath 25 respectively adjust the temperature of the absorption bottle 23. In actual sampling, a certain temperature and concentration of the absorption liquid can be maintained, which can reduce the volatilization of ammonia, increase the solubility of ammonia in the absorption liquid, reduce the chance of it escaping from the absorption liquid, and ensure the accuracy of the sampling results.

[0054] like Figure 2 As shown, the first sampling structure also includes an elastic mechanism 27, which is connected to the absorption bottle 23 and is used to adjust the pre-tightening force between the absorption bottle 23 and the first sampling nozzle 22.

[0055] For example, the elastic mechanism 27 includes an elastic element and a connecting post. The elastic element includes, but is not limited to, a spring. The elastic element is sleeved on the connecting post, and when the absorption bottle 23 contacts the first sampling nozzle 22, the elastic element is in a compressed state.

[0056] In the above process, the absorption bottle 23 is connected to the elastic mechanism 27, which ensures that the sampling bottle is always in close contact with the first sampling nozzle 22 during sampling, thus ensuring a tight seal. At the same time, it is very convenient to remove the sampling bottle from the first sampling nozzle 22 after sampling, which improves flexibility and makes operation easier.

[0057] like Figure 3 As shown, the first sampling structure also includes an elastic mechanism 27 and a guiding mechanism 28. Both the elastic mechanism 27 and the guiding mechanism 28 are connected to the absorption bottle 23. The elastic mechanism 27 is used to adjust the pre-tightening force between the absorption bottle 23 and the first sampling nozzle 22.

[0058] For example, the elastic mechanism 27 is located below the absorption bottle 23. The elastic mechanism 27 can be set to be the same as the elastic mechanism 27 in the above embodiment. However, the difference is that in this embodiment, the side wall of the absorption bottle 23 is also provided with the guide mechanism 28. The guide mechanism 28 includes, but is not limited to, guide posts, for guiding the absorption bottle 23.

[0059] In the above process, the absorption bottle 23 is connected to the elastic mechanism 27 and the guide mechanism 28, so that the absorption bottle 23 can move along the guide mechanism 28 under the action of the elastic mechanism 27, ensuring that the sampling bottle 23 is always in close contact with the first sampling nozzle 22 during sampling, thus ensuring the sealing. At the same time, it is very convenient to remove the sampling bottle from the first sampling nozzle 22 after sampling, which improves flexibility and makes operation convenient.

[0060] like Figure 1 As shown, the probe assembly includes a first probe 10, a second probe 11, a sampling filter cartridge 12, and a sampling filter membrane 13. One end of the first probe 10 is connected to the sampling filter cartridge 12. The sampling filter membrane 13 is connected between the first probe 10 and the second probe 11. The second probe 11 is connected to the second sampling structure and the first sampling structure, respectively. The second probe 11 includes, but is not limited to, a bent probe.

[0061] In the above implementation process, the probe assembly is equipped with a sampling filter cartridge 12 and a sampling filter membrane 13. When the sampling device 29 is working, ammonium salt can be sampled by the sampling filter cartridge 12 or the sampling filter membrane 13 in the high flow rate channel, and ammonia can be sampled by the absorption bottle 23 in the low flow rate channel. The combination is flexible and diverse, which can meet many environmental monitoring scenarios.

[0062] In some embodiments, the absorption bottle sampling device further includes a first temperature control component 30, which is configured as a first temperature control chamber for accommodating at least a portion of the structure of the first probe 10 and the sampling filter cartridge 12.

[0063] In the above process, the first temperature control component 30 can control the temperature of the first probe 10 and the sampling filter cartridge 12, for example, control their temperature at 220°C, reduce low temperature loss, avoid being affected by the temperature inside the chimney, realize individual temperature control according to the actual situation of the flue, and improve sampling reliability.

[0064] In some embodiments, the absorption bottle sampling device further includes a second temperature control component 40, wherein the control temperature of the first temperature control component 30 is consistent with the control temperature of the second temperature control component 40, and the second temperature control component 40 is configured to accommodate the second probe 11 and the sampling filter membrane 13, ensuring that the pipeline temperature after leaving the flue is continuously maintained at 220°C.

[0065] In the above process, the first temperature control component 30 and the second temperature control component 40 respectively control the temperature of different positions of the probe assembly, so that the probe assembly is always maintained at the specified temperature, reducing low temperature loss and ensuring sampling accuracy.

[0066] In all embodiments of this application, "large" and "small" are relative terms, "more" and "less" are relative terms, and "upper" and "lower" are relative terms. The embodiments of this application will not elaborate further on the expression of such relative terms.
