Description

Technical Field

[0001] The invention belongs to the technical field of carbon monoxide concentration detection, and particularly relates to a device for detecting carbon monoxide concentration in industrial flue gas. Background Art

[0002] Carbon monoxide (CO) is a colorless, odorless, and non-irritating toxic gas. High concentrations can cause poisoning and, in severe cases, even fatal. In industrial environments, particularly those involving combustion processes, ensuring safe levels of CO in the air is crucial. By detecting CO concentrations, potential safety hazards can be promptly identified and prevented, safeguarding the safety of production facilities and personnel. Existing CO (carbon monoxide) concentration detection devices typically rely on specific types of sensors and technologies, including electrochemical sensors and infrared absorption methods. Electrochemical sensors determine gas concentration by measuring the current generated when CO reacts with the electrolyte within the sensor. Infrared absorption methods rely on the absorption characteristics of CO of specific wavelengths of infrared light. Using an infrared light source and detector, CO absorbs light of specific wavelengths as it passes through the optical path, causing the light intensity to decrease. This change in intensity can be measured to calculate the CO concentration. Infrared absorption methods offer high accuracy and are suitable for continuous monitoring. However, in addition to carbon monoxide, industrial flue gas also contains particulate matter and dust, which is generally high-temperature humid gas. Once industrial flue gas enters the sampling pipeline and detection components, it is not only easy to cause blockage, affecting the normal gas flow, but also making the actual carbon monoxide concentration reaching the sensor unable to truly reflect the concentration of the source gas, thereby affecting the detection results, but also easily damaging the internal components of the detection equipment.

[0003] The existing Chinese patent document with the announcement number CN221594920U proposes a carbon monoxide concentration detection device, which solves the above technical problems by using a filter plate installed inside the housing in conjunction with a brush rod to enable the filter plate to filter impurities in the gas while also preventing the filter plate from being blocked. However, industrial flue gas is still a high-temperature and high-humidity gas, and entering the detection equipment will still cause equipment reading errors or directly damage the service life of the equipment.

[0004] Therefore, the present invention proposes an industrial flue gas carbon monoxide concentration detection device to solve the problem in the prior art that the detection equipment cannot remove high-temperature and high-humidity gases, for example, through filtering through a filter, and that high-temperature and high-humidity gases entering the detection equipment will cause equipment reading errors or directly damage the service life of the equipment. The gas pretreatment unit is improved and designed on the probe of the detection equipment to remove particulate matter in the flue gas after sampling, and the gas is subjected to certain heat dissipation and moisture absorption treatments to improve the accuracy and reliability of the detection results.

[0033] In order to clearly and completely describe the objectives and technical solutions of the present invention and make its advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1 to 14The present invention provides a technical solution: an industrial flue gas carbon monoxide concentration detection device, comprising an industrial flue gas detection mobile device 1, a carbon monoxide concentration infrared detection device 2 and a data analysis and processing device 3 are arranged above the industrial flue gas detection mobile device 1, a flue gas probe rack 11 is also fixedly installed above the industrial flue gas detection mobile device 1, and a flue gas suction probe assembly 4 is arranged above the flue gas probe rack 11; the industrial flue gas detection mobile device 1 is mainly used to install the carbon monoxide concentration infrared detection device 2 and the data analysis and processing device 3 so that the device can be moved, which is convenient for sampling and detecting industrial flue gas at different locations, and the flue gas suction probe assembly 4 is fixedly installed above the flue gas probe rack 11. The component 4 is fixedly installed above the industrial smoke detection mobile device 1 through the smoke probe frame 11. The exhaust pump 44 inside the smoke probe frame 11 works to extract industrial smoke. The carbon monoxide concentration infrared detection device 2 mainly includes an air chamber, which is equipped with an infrared light source and a detector. The infrared light source generates infrared light of a specific wavelength, which corresponds to the absorption peak of carbon monoxide molecules. The carbon monoxide concentration infrared detection device 2 also includes an optical filter that selectively transmits infrared light of a specific wavelength to accurately measure the absorption characteristics of carbon monoxide. The infrared detector receives the infrared light signal after passing through the gas sample and converts it into an electrical signal for output. In this embodiment, the gas delivery connecting pipe 441 is connected to the flow control valve port of the gas chamber inlet of the carbon monoxide concentration infrared detection device 2 through a delivery pipeline, and the pre-treated industrial flue gas is delivered to the gas chamber of the carbon monoxide concentration infrared detection device 2 and exposed to an infrared light source. The carbon monoxide molecules in the gas will absorb infrared light of a specific wavelength, reducing the light intensity reaching the detector. After receiving the weakened light signal, the detector converts it into an electrical signal and sends it to the data analysis and processing device 3 for analysis. The data analysis and processing device 3 calculates the carbon monoxide concentration based on the received electrical signal and outputs the result to the user, usually in digital form. It is presented in the form of a display screen. In this embodiment, the gas delivery connecting pipe 441 and the flow control valve at the air chamber inlet of the carbon monoxide concentration infrared detection device 2 need to be connected by a pipeline. The air chamber of the carbon monoxide concentration infrared detection device 2 is also designed with an exhaust port. After the detection, the industrial flue gas sample needs to be connected to a specific gas recovery and processing equipment through a pipeline to ensure that the gas discharged after the detection does not pollute the environment. In addition, the detector signal output end of the carbon monoxide concentration infrared detection device 2 needs to be connected to the input end of the data analysis and processing device 3 through an electric wire. The above are all conventional designs and are not described in detail in this embodiment and the accompanying drawings.The smoke gas intake probe assembly 4 includes a smoke gas intake probe 41 fixedly mounted on the upper surface of the smoke gas probe frame 11 by means of threads, an integrated sealing plate 43 and an air pump 44 are provided inside the smoke gas intake probe 41, a moisture absorption assembly 5 is provided on one side of the smoke gas intake probe assembly 4, the moisture absorption assembly 5 includes a water-absorbing silica gel pad 54, the integrated sealing plate 43 is fixedly mounted on the inner surface of the smoke gas intake probe 41, the air pump 44 is arranged on one side of the integrated sealing plate 43, a gas delivery connecting pipe 441 is fixedly mounted on the output end of the air pump 44, an air extraction ring pipe 442 is fixedly mounted on the input end of the air extraction pump 44, the gas delivery connecting pipe 441 passes through the bottom inner wall of the smoke gas intake probe 41, the air extraction ring pipe 442 is evenly distributed on the surface of one side close to the integrated sealing plate 43, the air extraction port 4421 passes through the inner wall of the integrated sealing plate 43, the integrated sealing plate A particle processing rack 431 is provided on the other side of 43. The particle processing rack 431 is trumpet-shaped. The wide end of the particle processing rack 431 is fixedly connected to the side surface of the integrated sealing plate 43. The outer surface of the particle processing rack 431 is evenly distributed with airflow particle separation guide pieces 432. The inner surface of the flue gas inhalation probe 41 is evenly distributed with guide fins 42. The guide fins 42 and the airflow particle separation guide pieces 432 are staggered. Particle diversion grooves 4322 are symmetrically provided on both sides of the airflow particle separation guide piece 432. Filter discs 4321 are symmetrically fixedly installed on the arc-shaped side walls of the airflow particle separation guide piece 432. Back-blowing grooves 4323 are symmetrically provided on the side wall of the airflow particle separation guide piece 432 close to the integrated sealing plate 43. The back-blowing grooves 4323 are slit-shaped, and the length of the back-blowing grooves 4323 is one-fourth of the length of the integrated sealing plate 43.

[0036] In this embodiment, the air pump 44 is installed inside the smoke suction probe 41 and is mainly used as a sampling pump for extracting industrial smoke samples. The air pump 44 extracts the industrial smoke through the air suction ring pipe 442 and allows it to enter the smoke suction probe 41 for pretreatment. Then, the smoke is transported to the air chamber of the carbon monoxide concentration infrared detection device 2 through the gas delivery connecting pipe 441. The integrated sealing plate 43 separates the pretreatment space inside the smoke suction probe 41. After the industrial smoke enters the smoke suction probe 41, the gas is evenly dispersed by the guide fins 42 due to the staggered design of the guide fins 42 and the air flow particle separation guide piece 432, and flows along the fin-shaped extension direction of the air flow particle separation guide piece 432. In addition, due to the particle treatment frame 431 and the air flow particle separation guide piece 432, the gas is uniformly dispersed by the guide fins 42 and flows along the fin-shaped extension direction of the air flow particle separation guide piece 432. The guide plate 432 is trumpet-shaped as a whole, so that large particles in the industrial flue gas deviate from their original trajectory due to inertia, hit the curved surface of the airflow particle separation guide plate 432, and are guided to the particle diversion grooves 4322 on both sides. The remaining small particles are filtered out by the filter plate 4321. This design can use the airflow guidance and separation effect of the airflow particle separation guide plate 432 to pre-separate large particle impurities and reduce the burden on the filter plate 4321. Compared with traditional filter plates, this design can ensure the effective graded filtration effect of the gas. The backflush groove 4323 is at the trumpet-shaped tail end of the airflow particle separation guide plate 432. The slit design not only prevents large particles of dust from entering, but also serves as a backflush groove, which can distribute the backflush airflow to blow away the large particle impurities on the particle diversion groove 4322.

[0037] Example 2

[0038] See also Figures 1 to 14On the basis of the first embodiment, in order to back-blow and clean the airflow particle separation guide plate 432, the present embodiment further proposes that a back-blow triangular nozzle 4324 is fixedly installed on one side of the filter 4321, an upper air outlet nozzle 43241 is symmetrically arranged on the oblique upper side of the side wall of the back-blow triangular nozzle 4324, and a side air outlet slot 43242 is symmetrically opened on the bottom of the side wall of the back-blow triangular nozzle 4324. A back-blow ring pipe 45 is arranged on the outside of the exhaust ring pipe 442, and back-blow conveying pipes 43 are evenly distributed on the inner side wall of the back-blow ring pipe 45 near the integrated sealing plate 43. 52, the back-blowing delivery pipe 452 passes through the inner wall of the integrated sealing plate 43 and is fixedly connected to the side wall of the back-blowing triangular nozzle 4324. The bottom of the back-blowing ring pipe 45 is fixedly installed with an air intake branch pipe 451, and the back-blowing ring pipe 45 passes through the bottom inner wall of the flue gas suction probe 41; in this embodiment, after the industrial flue gas has been tested several times, in order to avoid the flue gas suction probe 41 from weakening the pre-treatment effect of the flue gas, the back-blowing ring pipe 45 can be connected to the discharge valve of the compressed air storage tank through the air intake branch pipe 451. The compressed air storage tank can be selected according to actual conditions. It is not installed on the industrial smoke detection mobile device 1, so it is not shown in the attached drawings. The back-blowing ring pipe 45 conveys the back-blowing gas to the back-blowing triangular nozzle 4324 for spraying through the back-blowing conveying pipe 452. The back-blowing triangular nozzle 4324 not only seals the rear end of the airflow particle separation guide plate 432, but also sprays through the upper air outlet nozzle 43241 and the side air outlet slot 43242. The flat mouth shape of the upper air outlet nozzle 43241 not only increases the air flow rate and extends the airflow spraying path during the back-blowing gas spraying process, but also plays a guiding role. The back-blowing airflow is brought into contact with the filter 4321 to back-blow away the small particles remaining on the filter 4321. The side air outlet slots 43242 are distributed along the direction of the back-blowing slots 4323 and are narrow slots, so that the back-blowing gas is discharged through the back-blowing slots 4323 to blow away and clean the large particles of impurities remaining on the particle diversion slots 4322. The trumpet-shaped design of the airflow particle separation guide plate 432 and the particle treatment rack 431 allows the blown impurities to be diverted along the narrow mouth to the side of the flue gas inhalation probe 41 close to the moisture absorption component 5, which is convenient for later cleaning.

[0039] Example 3

[0040] See also Figures 1 to 14On the basis of the second embodiment, in order to pre-treat the industrial flue gas samples by cooling and absorbing moisture, this embodiment further proposes that the inner surface of the integrated sealing plate 43 is evenly distributed with a heat dissipation frame 433, the heat dissipation frame 433 and the airflow particle separation guide plate 432 are staggered, and arc-shaped heat dissipation guide surfaces 4331 are symmetrically provided on both sides of the heat dissipation frame 433. A closed inner layer frame 434 is provided on the inner side of the heat dissipation frame 433, one end of the closed inner layer frame 434 is fixedly connected to the side surface of the integrated sealing plate 43, and through grooves are evenly distributed in the middle of the closed inner layer frame 434. The moisture absorption component 5 includes a mounting cover 51, which is mounted on one side of the flue gas inhalation probe 41 by a threaded clamp. At the end, a smoke inlet cover 52 is fixedly installed on the inner side of the mounting cover 51, a middle closing box 53 is fixedly installed in the middle of the smoke inlet cover 52, a rotating rod 531 is rotatably installed inside the middle closing box 53, a sealing plug 532 is fixedly installed on one end of the rotating rod 531, the outer surface of the sealing plug 532 is sleeved with the inner surface of the narrow end of the particle treatment frame 431, a drainage port 5321 is provided on the bottom inner wall of the sealing plug 532, a water-absorbing silicone pad 54 is snap-fitted to the inside of the sealing plug 532, and the water-absorbing silicone pad 54 is snap-fitted between the closed inner frame 434 and the heat dissipation frame 433, and the air inlet 4421 is provided on both sides of the arc-shaped heat dissipation guide surface 4331;

[0041] In this embodiment, the heat dissipation skeleton 433 and the air flow particle separation guide plate 432 are staggeredly distributed, so that the industrial flue gas sample filtered by the filter 4321 is first guided along the arc-shaped heat dissipation guide surface 4331 when entering the particulate matter treatment rack 431. Heat dissipation strips are also evenly distributed on the arc-shaped heat dissipation guide surface 4331. While guiding, they exchange heat with the industrial flue gas, so that the temperature of the industrial flue gas is reduced to a certain extent. The industrial flue gas is sucked out by the exhaust ring 442 along the U-shaped channel between the arc-shaped heat dissipation guide surface 4331 and the water-absorbing silica gel pad 54 along the guiding effect of the arc-shaped heat dissipation guide surface 4331. In this process, the water-absorbing silica gel pad 54 can absorb moisture in the industrial flue gas to reduce humidity. The installation cover 51 is designed to install the flue gas inlet cover 52 and the middle closing box 53, so that the whole can be disassembled. The flue gas inlet cover 52 is mainly In order to extend the area for gas to pass through, the middle closing box 53 is installed with a water-absorbing silica gel pad 54 through a rotating rod 531 and a sealing plug 532, so that the water-absorbing silica gel pad 54 can be pulled out for replacement or cleaning, and the rotating rod 531 can be rotated so that the water-absorbing silica gel pad 54 as a whole can be rotated and deformed between the heat dissipation frame 433 and the closed inner layer frame 434. Because the heat dissipation frame 433 is arranged at intervals, the water-absorbing silica gel pad 54 is squeezed and deformed with the cooperation of the closed inner layer frame 434, and the protruding part can absorb moisture. When the water-absorbing silica gel pad 54 is rotated, the protruding part will be squeezed, so that the absorbed moisture will be discharged through the through groove in the middle of the closed inner layer frame 434. The sealing plug 532 is a hollow structure, which not only serves to seal the narrow opening of the particle treatment frame 431, but also allows heat and moisture to be discharged through the drainage port 5321 at the front end.

[0042] Example 4

[0043] See also Figures 1 to 14 Based on the fourth embodiment, this embodiment further proposes a detection method for an industrial flue gas carbon monoxide concentration detection device, comprising the following steps:

[0044] Step 1: Sampling is performed, the air pump 44 operates to extract industrial flue gas samples through the air extraction ring pipe 442;

[0045] In step 2, the industrial flue gas sample enters the flue gas inlet probe 41 for pretreatment. After entering the flue gas inlet probe 41, the industrial flue gas is evenly dispersed by the guide fins 42 and flows along the fin-shaped extension direction of the airflow particle separation guide piece 432, so that the large particles in the industrial flue gas deviate from the original trajectory due to inertia, hit the arc surface of the airflow particle separation guide piece 432, and are guided to the particle diversion grooves 4322 on both sides. The remaining small particles are filtered out by the filter 4321. Then, when the industrial flue gas sample enters the particle treatment rack 431, it is guided along the arc-shaped heat dissipation guide surface 4331. The heat dissipation strips on the arc-shaped heat dissipation guide surface 4331 exchange heat with the industrial flue gas while guiding the flow, so that the temperature of the industrial flue gas is reduced to a certain extent. The industrial flue gas follows the guiding effect of the arc-shaped heat dissipation guide surface 4331 and flows along the U-shaped channel between the arc-shaped heat dissipation guide surface 4331 and the water-absorbing silica gel pad 54, and the water-absorbing silica gel pad 54 absorbs moisture in the industrial flue gas to reduce the humidity.

[0046] Step three, perform carbon monoxide concentration detection. The vacuum pump 44 extracts the pretreated industrial flue gas sample and connects the delivery pipeline to the flow control valve port of the air chamber inlet of the carbon monoxide concentration infrared detection equipment 2 through the gas delivery connecting pipe 441. The pretreated industrial flue gas is input into the air chamber of the carbon monoxide concentration infrared detection equipment 2 and exposed to the infrared light source. The carbon monoxide molecules in the gas will absorb infrared light of a specific wavelength, reducing the light intensity reaching the detector. After receiving the weakened light signal, the detector converts it into an electrical signal and sends it to the data analysis and processing equipment 3 for analysis. The data analysis and processing equipment 3 calculates the carbon monoxide concentration based on the received electrical signal and outputs the result to the user in the form of a digital display screen.
