Description

Technical Field

[0001] This invention relates to the field of industrial carbon emission outlet monitoring technology, specifically to an industrial carbon emission outlet monitoring pretreatment system and monitoring method. Background Technology

[0002] Industrial chimneys are currently a major source of carbon emissions, and their monitoring needs are directly related to carbon emission accounting in industries such as thermal power generation and chemicals. Traditional carbon emission monitoring mainly relies on the accounting method, which uses data such as emission factors, raw material and fuel usage, and carbon balance theory to calculate direct and indirect emissions of greenhouse gases such as carbon dioxide. However, the accounting method suffers from drawbacks such as significant human interference and large errors. Therefore, there is a growing trend towards using measured carbon emission accounting methods, which can greatly improve the accuracy and real-time nature of carbon emission accounting data. However, adopting the measured carbon emission accounting method requires actual data measurement. The following problems exist in the actual measurement of carbon dioxide data from industrial chimneys:

[0003] 1. Carbon dioxide monitoring equipment is a precision device. Besides frequent calibration as needed, the harsh environment of industrial chimneys, with their high temperatures, humidity, dust, and corrosive gases, means that during detection, in addition to dust affecting sensor accuracy, environmental factors such as temperature and pressure within the chimney also influence the equipment's accuracy. For example, temperature changes alter the sensor's response characteristics, affecting measurement results; high-speed airflow due to thermal noise can cause sensor temperature drift (e.g., a 0.1℃ change can result in a 0.3–0.5% concentration deviation). Pressure changes cause fluctuations in gas flow rate; for instance, in non-dispersive infrared (NDIR) methods, there is an optical path dilution effect: a sudden increase in flow rate shortens the time gas molecules spend in the detection chamber, reducing the integrated value of the infrared absorption peak (experimental data: with a flow rate fluctuation of ±30%, the CO2 concentration error reaches ±8%). Although relevant equipment was found before the test, it is mainly used to filter and cool the flue gas in the chimney. However, the existing equipment mainly relies on filter screens. Filter screens are prone to clogging, which not only makes maintenance inconvenient but also increases the cost of filter replacement. At the same time, during the monitoring process, the gas flow can fluctuate due to clogging, which will affect the monitoring values.

[0004] 2. Working at heights presents inconveniences. Conducting carbon measurements on chimneys requires technicians to climb to the chimney monitoring points (such as chemical chimneys, which can reach hundreds of meters in height, with high-level monitoring points exceeding 30 meters). In particular, some chimneys only have C-shaped climbing poles installed on the outer wall. When technicians climb to the height using these poles, their physical strength is already greatly depleted. Furthermore, due to the limited working environment and lack of effective equipment support points, they can only carry portable carbon monitoring instruments. Carrying additional equipment such as pretreatment devices during the monitoring process presents even greater challenges and can easily lead to accidents. Summary of the Invention

[0016] The method for monitoring industrial carbon emission outlets uses the industrial carbon emission outlet monitoring pretreatment system described above, and the steps are as follows:

[0017] S1: Dual-path gas intake is performed on the flue gas from the carbon emission outlet, and the dual gas sources are pressurized and input into the flue gas mixing chamber through the first and second intake ducts;

[0018] S2: The flue gas is compressed by the gradually narrowing cavity from the inside to the outside of the flue gas mixing chamber, which drives the small solid particles to aggregate into large solid particles.

[0023] S2: The lifting slide on the control bracket body is raised, causing the aligning cone to press into the conical aligning cavity of the cone aligner. By continuously raising the lifting slide, the vertical conical aligning cavity acts on the lifting slide, causing the central axis of the lifting slide to be vertical, thereby achieving the vertical alignment of the flue gas dust removal device.

[0024] S3: The reaction force of the conical positive positioning cavity on the lifting slide causes the L-shaped clamping plate to move downward relative to each other, thereby achieving mutual compression between the L-shaped clamping plate and the supporting clamping plate, and thus achieving the positive positioning and fixation of the flue gas dust removal device.

[0033] The above description is a detailed explanation of this patent in conjunction with specific embodiments, and it should not be construed that the specific embodiments of this patent are limited to the above description. For those skilled in the art, any substitutions or modifications made to the described embodiments without departing from the concept of this patent should be considered within the scope of protection of this patent. In this specification, specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification and the features of different embodiments or examples. Although the embodiments of the present invention and their advantages have been described in detail, it should be understood that various changes, substitutions, and modifications can be made herein without departing from the scope of protection of the patent application.

[0034] Industrial carbon emission outlet monitoring and pretreatment systems, such as Figures 1-5As shown, the device includes a flue gas dust removal device 1, which includes a centrifugal rotating disk 29 and a fixed disk 15. The cross-sections of the centrifugal rotating disk 29 and the fixed disk 15 are V-shaped, and the included angle of the V-shape of the fixed disk 15 is greater than that of the centrifugal rotating disk 29. The fixed disk is positioned above the centrifugal rotating disk, causing the fixed disk and the centrifugal rotating disk to form a flue gas mixing chamber 14. The height of the flue gas mixing chamber 14 gradually decreases from the inside to the outside. The function of this structure is that after the flue gas is injected, it flows from the center outward and upward, while the size of the flue gas mixing chamber 14 gradually narrows. As the flue gas is gradually compressed through the flue gas mixing chamber, the probability of solid particles (dust, etc.) in the flue gas colliding with each other during the movement will be significantly increased. Frequent collisions will cause the particles to aggregate and form larger particle clusters, causing the large particles to fall onto the centrifugal rotating disk 29 and be centrifugally thrown out by the centrifugal rotating disk. The fixed plate 15 and the centrifugal turntable 29 are respectively provided with a first air inlet and a second air inlet at their centers. The first and second air inlets are pressurized and supplied with air by an air supply device. In some embodiments, the air supply device can be an air pump or a blower, etc. The purpose of using two airflows is to promote the convergence and mixing of the two flue gas flow streams in the flue gas mixing chamber 14, increase the probability of solid particle collision, and improve the dust removal effect. At the same time, dual-path air sampling allows for the selection of two sampling points simultaneously, and the monitored data will be closer to the true value and improve monitoring efficiency. In use, the two flue gas streams enter the flue gas mixing chamber from the first air inlet and the second air inlet, respectively, and flow along the outer side of the flue gas mixing chamber. Small solid particles in the flue gas collide to form large solid particles.

[0035] like Figure 2 As shown, the outer side of the fixed plate 15 is provided with a plurality of air outlets 16, the positions of which are larger than 1 / 2 of the diameter of the fixed plate, and the plurality of air outlets 16 are arranged around the fixed plate 15. A solid particle collection tank 13 is provided on the outer periphery of the flue gas mixing chamber 14. The solid particle collection tank 13 is configured as a sealed structure to ensure that the gas after dust removal flows out from the air outlets 16. In some embodiments, a particulate matter attachment mesh can also be provided inside the solid particle collection tank 13. In this embodiment, as... Figure 5 As shown, the top end 14-1 of the flue gas mixing chamber 14 is a narrow slit structure, such as a height of less than 5cm. The function of this structure is to reduce the backlash of solid particles after they are thrown out.

[0036] Optionally, in this embodiment, a fan-blade method is used for pressurization, such as... Figure 2As shown, a first fan blade 28 is provided inside the first air intake duct, and a first air inlet 26 is provided above the first fan blade 28. The first fan blade 28 is driven by a first motor (preferably a variable frequency motor), and the fan blade shaft is connected to the first air intake duct by a sealed bearing. An air sampling pipe is connected to the outside of the first air inlet 26 and extends into the chimney sampling point to take samples. A second fan blade 30 is provided inside the second air intake duct, and a second air inlet 35 is provided below the second fan blade 30.

[0037] Optionally, the rotating shaft of the second fan blade 30 is connected to the second air intake through several connecting rods; the lower part of the second air intake is rotatably connected to the support sleeve 32 through a sealed bearing. The support sleeve 32 is provided with the second air inlet 35, and the second motor 33 (preferably a variable frequency motor) for driving the second fan blade 30 and the centrifugal turntable 29 is located externally. Its rotating shaft is connected to the lower part of the support sleeve 32 through a sealed bearing. In this embodiment, the support sleeve 32 serves as one of the supports for the centrifugal turntable 29. To improve operational stability, the upper part of the centrifugal turntable 29 is connected to the device body through a rolling bearing 27. During startup, the second fan blade 30 and the centrifugal turntable 29 rotate synchronously at high speed, and the flue gas in the support sleeve 32 is drawn upward into the flue gas mixing chamber 14.

[0038] Optional, such as Figure 2 As shown, a gas collection chamber 2 is provided above the fixed plate 15, and the gas collection chamber 2 communicates with the flue gas mixing chamber 14 through the air outlet 16. To achieve rapid cleaning of the flue gas dust removal device and ensure its continuous use, such as... Figures 1-2 As shown, in this embodiment, the section below the centrifugal disc 29 constitutes the lower section, and the section above the fixed disc 15 constitutes the upper section 4; the lower section and the upper section are detachably connected (a sealing structure, such as a sealing ring, is provided at the connection point), that is, combined Figure 2 As can be seen, after the lower section and the lower section are combined, the flue gas mixing chamber 14 is formed between the two, thereby cleaning the solid particle collection tank 13, the centrifugal disc 29 and the stationary disc 15.

[0039] In other specific embodiments, such as Figure 5 As shown, a guide disk 14-2 is also provided between the first fan blade 28 and the second fan blade 30. The guide disk 14-2 is fixedly connected to the fixed disk 15 by several support rods. The guide disk 14-2 has a flat disk-shaped structure that is thick in the center and thin at the outer periphery. It is used to guide the flue gas ejected from the first air intake and the second air intake to the outer periphery, so as to promote the convergence of the two airflows at the outer periphery and improve the effect of the airflow converging at the outer periphery of the flue gas mixing chamber 14.

[0040] Compared with traditional filter dust removal methods, this implementation scheme is less prone to clogging during operation, maintains the continuous stability of the downstream airflow, and provides a stable gas source for subsequent gas monitoring.

[0041] Optional, such as Figures 1-2 As shown, a gas cooling device is also provided above the gas collection chamber 2; the gas cooling device includes a gas cooling chamber 22, and one or more cooling plates are provided inside the gas cooling chamber 22; the cooling plate includes an upper partition and a lower partition, and the cross-sections of the upper partition and the lower partition are both V-shaped, and a cold air chamber 23 is provided between the upper partition and the lower partition; the cold air chamber 23 communicates with the outside; a plurality of heat dissipation pipes 19 are arranged longitudinally inside the cold air chamber 23; the heat dissipation pipes 19 penetrate... The upper and lower partitions are connected; a cold air inlet pipe 20 is provided in the middle of the cold air cavity 23, and an air supply device 18 is provided at the air inlet end of the cold air inlet pipe 20. A cold air inlet cavity 3 is provided below the cold air inlet pipe, and the cold air inlet cavity 3 is located between the gas collection cavity 2 and the gas cooling cavity 22; several ventilation holes 25 are provided on the side wall of the cold air inlet cavity 3; the gas collection cavity 2 and the gas cooling cavity 22 are connected by several gas delivery pipes 17. In use, the air supply device 18 draws air, and external cold air is drawn into the cold air inlet pipe 20 through the ventilation holes 25, flows through the cold air cavity 23 to dissipate heat from the heat dissipation pipe 19, and is then directly discharged to the outside; the advantage of this structure is that it improves the smoothness of the cooling airflow and the heat exchange effect, and the heat dissipation effect is controlled by adjusting the wind speed of the motor (preferably a variable frequency motor) of the air supply device 18. At the same time, in this embodiment, as Figures 1-3 As shown, the gas cooling device is provided with two sections. The upper gas cooling device 5 is detachably connected to the lower gas cooling device, and a sealing structure is provided at the connection point. Meanwhile, as... Figures 2-3 As shown, a first connector is provided at the upper end of the cold air inlet pipe 20, and a sealing ring 21 is provided at the first connector; the upper section of the gas cooling device 5 is provided with a second connector 40 corresponding to the cold air inlet pipe 20, and the second connector 40 is detachably connected to the first connector; the use of a bipolar gas cooling device can effectively cool high-temperature gas to the ideal temperature range required for monitoring, and has a wider range of applicability (such as the temperature of flue gas from non-ferrous tin smelting is about 60-70℃, while the temperature of flue gas from alkali furnaces in paper mills is about 110℃). A monitoring area 6 is provided at the top of the upper section of the gas cooling device 5, and an exhaust port 37 is provided at the top of the monitoring area 6. In some embodiments, an exhaust regulating valve (not shown) can also be provided at the exhaust port 37; a monitoring instrument socket 38 is provided on the side wall of the monitoring area 6; a sensor (not shown) is provided in the monitoring area 38, and the sensor is a temperature sensor and / or a pressure sensor and / or a flow sensor.

[0042] When using, such as Figures 2-3 As shown, the high-temperature gas after dust removal enters the gas cooling chamber 22 from the gas collection chamber 2, then flows upward through the heat dissipation pipe 19, and finally enters the monitoring zone 6. The monitoring zone 6 is the monitoring zone of the gas monitoring device (such as a carbon dioxide monitoring device). The monitoring zone 6 is under positive pressure and can regulate the air temperature and / or air pressure and / or flow rate, providing a reliable monitoring space for gas monitoring and ensuring the accuracy of the data.

[0043] Optionally, the flue gas dust removal device 1 described in this application is preferably fixed in a vertical position during operation to ensure the stability of the operation of centrifugal and other related components and the dust removal effect. Therefore, in order to improve the safety of high-altitude operations and the convenience of fixed operation, this application also provides quick-fixing components, such as... Figure 1 and Figure 6 As shown, the quick-fixing assembly includes a support plate, a cone-shaped aligner 9, and a fixing bracket 41. In this embodiment, a first support plate 8 and a second support plate 11 are provided, which are respectively positioned above and below the cone-shaped aligner 9. One side of the support plate is connected to the outer wall of the chimney (optionally, expansion bolts are driven into the chimney and then connected via a connecting rod 47). The first support plate 8 has a longitudinally arranged locking hole 48, and the second support plate 11 has a locking hole 45. The cone-shaped aligner 9 includes a conical aligning cavity 46, one side of which is connected to the outer wall of the chimney. The fixing bracket is attached to the flue gas dust removal device. The fixing bracket 41 includes a bracket body, one side of which is provided with a first L-shaped locking plate 7 and a second first L-shaped locking plate 44 corresponding to the support plate. The bracket body is provided with a lifting assembly, such as a telescopic cylinder assembly. In this embodiment, a manual telescopic assembly can be selected, i.e., a... Figure 6 As shown, an I-shaped screw 12 is rotatably mounted, and a lifting slide 43 is mounted on the screw 12. Rotation of the screw 12 causes the non-circular lifting slide 43 to rise and fall within the lifting groove 42. A positioning cone 10 is positioned on one side of the lifting slide 43 corresponding to the conical positioning cavity. Rotation of the screw allows the lifting slide to rise and fall, thereby enabling the positioning cone to be lifted and lowered into or removed from the conical positioning cavity. During processing, it is preferable that the central axis of the positioning cone 10 is parallel to the axis of the centrifugal turntable 29. That is, during use, ensuring the positioning cone 10 is vertical ensures that the centrifugal turntable 29 is vertical.

[0044] The method for monitoring industrial carbon emission outlets uses the industrial carbon emission outlet monitoring pretreatment system described above, and the steps are as follows:

[0045] S1: Dual-path gas intake is performed on the flue gas from the carbon emission outlet, and the dual gas sources are pressurized and input into the flue gas mixing chamber through the first and second intake ducts;

[0046] S2: The flue gas is compressed by the gradually narrowing cavity from the inside to the outside of the flue gas mixing chamber, which drives the small solid particles to aggregate into large solid particles. The solid particles are then centrifugally thrown out by a high-speed rotating centrifugal disc to achieve flue gas dust removal and obtain dust-removed gas.

[0047] S3: The dust removal gas is introduced into a gas cooling device for cooling. The temperature and / or pressure and / or flow rate of the dust removal gas in the monitoring area are monitored by sensors in the monitoring area. The temperature and / or pressure and / or flow rate of the dust removal gas in the monitoring area are adjusted by regulating the flow rate of the first and second air inlets or by adjusting the opening of the exhaust regulating valve; or the temperature of the dust removal gas is adjusted by the gas cooling device.

[0048] S4: Obtain dust removal gas with stable temperature and / or stable pressure and / or stable flow rate within the monitoring area; S5: Monitor the dust removal gas within S4 using gas monitoring equipment.

[0049] The flue gas dust removal device is positioned and fixed in place as follows:

[0050] S1: Align the fixed bracket on one side of the flue gas dust removal device with the support plate on the outer wall of the chimney. First, insert the end of the L-shaped plate into the hole of the support plate. That is, when working at height, the first L-shaped plate 7 and the second L-shaped plate 44 are respectively pressed above the first support plate 8 and the second support plate 11, and are respectively inserted into the holes 48 and 45. First, hang the device on the support plate to reduce the operator's burden and facilitate other operations.

[0051] S2: The lifting slide on the control bracket body is raised, causing the aligning cone to press into the conical aligning cavity of the cone aligner. By continuously raising the lifting slide, the vertical conical aligning cavity acts on the lifting slide, causing the central axis of the lifting slide to be vertical, thereby achieving the vertical alignment of the flue gas dust removal device.

[0052] S3: The reaction force of the conical positive positioning cavity on the lifting slide causes the L-shaped clamping plate to move downward relative to each other, thereby achieving mutual compression between the L-shaped clamping plate and the supporting clamping plate, and thus achieving the positive positioning and fixation of the flue gas dust removal device.

[0053] When working at height, the positioning and fastening of the flue gas dust removal device can be achieved simply by controlling the lifting and lowering of the lifting slide 43. The operation is quick and convenient, reducing labor intensity and improving operational safety.

A method for monitoring industrial carbon emission outlets, characterized in that, The monitoring is performed using the industrial carbon emission outlet monitoring pretreatment system as described in claim 10, with the following steps: S1: Dual-path gas intake is performed on the flue gas from the carbon emission outlet, and the dual gas sources are pressurized and input into the flue gas mixing chamber through the first and second intake ducts; S2: The flue gas is compressed by the gradually narrowing cavity from the inside to the outside of the flue gas mixing chamber, which drives the small solid particles to aggregate into large solid particles. The solid particles are then centrifugally thrown out by a high-speed rotating centrifugal disc to achieve flue gas dust removal and obtain dust-removed gas. S3: The dust removal gas is introduced into a gas cooling device for cooling. The temperature and / or pressure and / or flow rate of the dust removal gas in the monitoring area are monitored by sensors in the monitoring area. The temperature and / or pressure and / or flow rate of the dust removal gas in the monitoring area are adjusted by regulating the flow rate of the first and second air inlets or by adjusting the opening of the exhaust regulating valve; or the temperature of the dust removal gas is adjusted by the gas cooling device. S4: The dust removal gas obtained in the monitoring area has a stable temperature and / or stable pressure and / or stable flow rate; S5: Use gas monitoring equipment to monitor the dust removal gas in S4.

12. The method for monitoring industrial carbon emission outlets according to claim 11, characterized in that, The flue gas dust removal device is positioned and fixed in place as follows: S1: Align the fixed bracket on one side of the flue gas dust removal device with the support plate on the outer wall of the chimney, and first insert the end of the L-shaped plate into the card hole of the support plate. S2: The lifting slide on the control bracket body is raised, causing the aligning cone to press into the conical aligning cavity of the cone aligner. By continuously raising the lifting slide, the vertical conical aligning cavity acts on the lifting slide, causing the central axis of the lifting slide to be vertical, thereby achieving the vertical alignment of the flue gas dust removal device. S3: The reaction force of the conical positive positioning cavity on the lifting slide causes the L-shaped clamping plate to move downward relative to each other, thereby achieving mutual compression between the L-shaped clamping plate and the supporting clamping plate, and thus achieving the positive positioning and fixation of the flue gas dust removal device.
