[0067] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0068] The following describes the smoke content measurement method and device, electronic device and storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0069] Figure 1 A schematic flow chart of a method for measuring flue gas content provided in an embodiment of the present disclosure.

[0070] like Figure 1 As shown, the method comprises the following steps:

[0071] Step 101 , performing gas pretreatment on the gas to be detected to obtain a target gas; wherein the target gas has at least the characteristics of being free of acid mist and ammonium salt crystals.

[0072] In the embodiments of the present disclosure, when the gas to be detected is pretreated, it can be processed by but not limited to: cold drying extraction, dynamic phosphoric acid titration technology. Gas pretreatment can reduce the moisture generated during the sampling process and reduce the loss of the gas to be detected. At the same time, it can avoid the formation of ammonia salt crystals to cause blockage, interfere with measurement, avoid dust blockage and formation of acid mist, etc., and can solve the problem of large errors in low concentration measurements.

[0073] Gas pretreatment is to convert the sample of the gas to be detected into a form suitable for analysis and measurement. During the gas pretreatment process, factors that may interfere with the measurement results, such as acid mist, ammonium salt crystals, etc., need to be removed or reduced. In flue gas, acid mist is usually a tiny droplet formed by the combination of acid gases such as sulfuric acid and nitric acid with water vapor. During the gas pretreatment process, cold-drying extraction, including cooling and drying steps, can effectively remove moisture from the flue gas, thereby preventing the formation of acid mist. In addition, the filtration step may also be used to capture and remove the acid mist particles that have already formed.

[0074] Ammonium salt crystals may form in gas samples, especially in environments containing ammonia and acidic gases (such as SO2, NOx). These gases can react to form ammonium salts under appropriate conditions. During gas pretreatment, the crystallization of ammonium salts can be prevented by controlling the pH value and temperature of the absorption liquid. Dynamic phosphoric acid titration technology can play a role in this process. By accurately controlling the amount of phosphoric acid added, the pH value of the solution can be adjusted to avoid the formation of ammonium salts.

[0075] The target gas is a purer gas obtained by removing or reducing interfering substances such as acid mist and ammonium salt crystals from the gas to be detected. The target gas can improve the accuracy and reliability of subsequent detection.

[0076] The gas pretreatment process uses cold drying to extract and remove moisture, particulate matter and acid mist, and uses dynamic phosphoric acid titration technology to remove acidic gases and prevent ammonium salt crystallization. The target gas finally obtained has the characteristics of no acid mist and no ammonium salt crystallization, providing a high-purity sample for subsequent gas composition analysis. It can improve the accuracy and repeatability of gas detection and is suitable for strict environmental monitoring and industrial emission control requirements.

[0077] Step 102, transmitting the first ultraviolet light beam to a preset detector through the target gas to obtain first measurement data, and transmitting the second ultraviolet light beam to the preset detector through a preset medium to obtain second measurement data; wherein the first ultraviolet light beam and the second ultraviolet light beam are obtained by beam averaging the ultraviolet light beam emitted by a preset light source.

[0078] In the embodiment of the present disclosure, the preset detector is a gas analysis device selected by a user, such as an ultraviolet gas analyzer, etc. The preset detector can be an analyzer with a multi-component integrated design, having non-dispersive ultraviolet absorption method SO2 analysis, non-dispersive infrared absorption method NO x Analysis, electrochemical O2 analysis and other functions.

[0079] In order to facilitate understanding of the implementation process of the embodiment of the present disclosure, the embodiment of the present disclosure provides a schematic diagram of the measurement process of the smoke content, such as Figure 2 As shown, the double-beam spectrometer based on a specific molecular absorption uses a solid-state LED ultraviolet light source. In pulse mode, the ultraviolet beam passes through the measurement chamber and is absorbed and attenuated, and the concentration of the measured component is calculated according to the Lambert-Beer law. Figure 2 As shown, the ultraviolet light of the solid-state LED ultraviolet light source (1) (i.e., the two light source emitting ends of the preset light source) is evenly divided by the light velocity separator (2), and one light beam (i.e., the first ultraviolet light beam) passes through the sample gas chamber (3) (i.e., the target) and enters the photoelectric detector (4) (i.e., one light receiving end of the preset detector) for detection, and one light beam (i.e., the second ultraviolet light beam) is used as a reference light beam and enters the photoelectric detector (5) (i.e., the other light receiving end of the preset detector) for reference measurement.

[0080] The preset medium is a user-defined medium, such as air, vacuum equipment, etc. Specifically, the preset medium is not limited in the embodiment of the present disclosure.

[0081] The absorption characteristics of the ultraviolet beam are used to detect the gas composition, the beam averaging technology is used to ensure the consistency of the measurement, and a calibration benchmark is provided through a reference medium, thereby improving the accuracy and reliability of the gas composition measurement.

[0082] Step 103: Perform data analysis and processing based on the first measurement data and the second measurement data to obtain a flue gas measurement result.

[0083] In the embodiment of the present disclosure, the smoke measurement result can be obtained by performing data analysis and processing on the first measurement data and the second measurement data through the preset detector.

[0084] The method for measuring flue gas content provided by the present disclosure performs gas pretreatment on the gas to be detected to obtain a target gas; wherein the target gas has at least the characteristics of being free of acid mist and ammonium salt crystals; a first ultraviolet light beam is transmitted to a preset detector through the target gas to obtain first measurement data, and a second ultraviolet light beam is transmitted to the preset detector through a preset medium to obtain second measurement data; wherein the first ultraviolet light beam and the second ultraviolet light beam are obtained by beam averaging the ultraviolet light beam emitted by a preset light source; data analysis and processing are performed based on the first measurement data and the second measurement data to obtain a flue gas measurement result. Compared with the related art, the embodiment of the present disclosure performs gas pretreatment on the gas to be detected to ensure that the obtained target gas is free of acid mist and ammonium salt crystals. At the same time, the detection of gas through ultraviolet light beams can reduce the interference of other gases and ammonium salt crystals in the flue gas, and improves the measurement accuracy when measuring the SO2 content in the flue gas.

[0085] In one implementable manner of the embodiment of the present disclosure, when performing gas pretreatment on the gas to be detected, it can also be implemented by but not limited to the following methods: performing gas sampling processing on the gas to be detected by cold drying extraction to obtain the sampled gas; performing gas pretreatment on the sampled gas by dynamic phosphoric acid titration to obtain the target gas.

[0086] In the disclosed embodiment, when performing the cold-drying extraction, at least the following steps are included: Extraction: extract the gas to be detected to ensure the representativeness and real-time nature of the sample. Cooling: cool the extracted gas to be detected by a cooling device to lower the gas temperature and cause the moisture in the gas to condense into a liquid state for subsequent removal. Drying: on the basis of cooling, further remove moisture from the gas by using a desiccant (such as silica gel, molecular sieve, etc.) to prevent moisture from interfering with subsequent detection. Filtration: during the extraction process, a filtration step is also included, using an appropriate filter to remove particulate matter and acid mist in the gas to ensure that the target gas is free of acid mist characteristics.

[0087] When the treatment is carried out by dynamic phosphoric acid titration technology, the following steps can also be used: Absorption: The gas treated by the cold drying method is passed through an absorption solution containing phosphoric acid, and the phosphoric acid reacts with the acidic gas (such as SO2) in the flue gas to form phosphates, thereby removing these acidic components. Titration: During the absorption process, the consumption of phosphoric acid is proportional to the content of acidic gas in the gas. Through dynamic titration technology, that is, real-time monitoring and adjustment of the amount of standard alkaline solution added, the consumption of phosphoric acid can be accurately determined, thereby calculating the content of acidic gas. Preventing ammonium salt crystallization: During the absorption and titration process, by controlling the pH value and temperature of the solution, the formation of ammonium salts (such as ammonium sulfate) can be prevented to ensure that the target gas has no ammonium salt crystallization characteristics.

[0088] In one implementable manner of the embodiment of the present disclosure, when the gas to be detected is sampled by cold-drying extraction, it can also be implemented in but not limited to the following manner: the gas to be detected is sampled by a preset heating sampling device to obtain a first gas; wherein the preset heating sampling device is used to reduce the moisture in the sampling process and the loss of the first substance in the gas to be detected; the first gas is filtered by a preset filtering device, and the preset filtering device is back-blown by a preset purge device to obtain a second gas; wherein the preset filtering device is used to filter solid matter in the first gas, and the preset purge device is used to remove the solid matter; the second gas is heated by a preset heating device to obtain the sampled gas, wherein the preset heating device is used to prevent the generation of condensed water.

[0089] In the disclosed embodiment, the gas to be detected in the flue is taken out and transported to the pretreatment unit, and sampling, filtering, heating and back-blowing are performed to avoid dust blockage and formation of acid mist.

[0090] The preset heating sampling device, preset filtering device, preset purge device and preset heating device are all custom-set devices, such as: a heated sampling probe (preset heating sampling device), a filter element made of nickel-titanium alloy material (preset filtering device), a gas storage tank (preset purge device) and a heating unit (preset heating device), etc. Specifically, with regard to the preset heating sampling device, preset filtering device, preset purge device and preset heating device, the embodiments of the present disclosure do not limit them.

[0092] In one implementable manner of the embodiment of the present disclosure, when the sampled gas is subjected to gas pretreatment by dynamic phosphoric acid titration, it can also be implemented in but not limited to the following manner: the sampled gas is transmitted to a preset phosphoric acid titration device via a preset fast bypass; wherein the preset fast bypass is used to reduce the adsorption of the sampled gas by the pipeline; and the sampled gas is subjected to dynamic phosphoric acid titration treatment in the preset phosphoric acid titration device to obtain the target gas.

[0093] In the embodiments of the present disclosure, the preset fast bypass and the preset phosphate titration device are custom-set devices, such as: a fast pipeline (preset fast bypass), a phosphate titration box (preset phosphate titration device), etc. Specifically, the embodiments of the present disclosure do not limit the preset fast bypass and the preset phosphate titration device.

[0094] Among them, when performing the pretreatment of the sampled gas, the following methods and features can be used but are not limited to: 1) Use a heated sampling probe to reduce the moisture generated during the sampling process. 2) Configure a fast bypass in the pretreatment system to reduce pipeline adsorption and shorten the system lag time. 3) Use dynamic phosphoric acid titration technology to reduce the loss of the gas to be tested, while avoiding the formation of ammonium salt crystals to cause blockage and interfere with the measurement.

[0095] In one implementable method of the disclosed embodiment, after obtaining the flue gas measurement results, the flue gas measurement results need to be first stored in an industrial computer and then uploaded to the Environmental Protection Bureau for environmental testing. However, in the process of uploading the flue gas measurement results to the Environmental Protection Bureau, there are many intermediate links, which can easily cause data interruption and affect data efficiency and upload rate. Therefore, in order to improve data efficiency and upload rate, the following method can also be used but is not limited to: sending the flue gas measurement results to a preset platform.

[0096] In the embodiment of the present disclosure, the preset platform is a predetermined platform, such as: an environmental protection bureau data acquisition instrument, etc. Specifically, the embodiment of the present disclosure does not limit the preset platform.

[0097] The disclosed embodiment eliminates the need for an industrial computer, and the smoke measurement results are directly uploaded from the smoke content measurement system to the environmental protection bureau data acquisition instrument, thus reducing the intermediate links of data loss.
