Description

Technical Field

[0001] The present invention relates to the technical field of carbon capture and storage, and in particular to a carbon capture pipe network ultrasonic cleaning system and method. Background Art

[0002] With the increasing concern about environmental protection and climate change, carbon capture technology plays an important role in reducing greenhouse gas emissions. Among them, organic amine solvent absorption is one of the most commonly used carbon capture technologies. However, in actual operation, organic amine solvents are susceptible to oxidation and thermal degradation, external introduction and pipeline corrosion during the regeneration process, resulting in dehydration crystallization, high molecular weight degradation products and other pollutants.

[0003] These pollutants accumulate in the pipe network of the carbon capture system, which can easily cause pipe network blockage, thereby affecting the carbon capture efficiency. In related technologies, when the pipe network of the carbon capture system is blocked by dehydration crystallization and degradation products, it is often necessary to stop the machine and dismantle it to check the pipe network point by point, which is time-consuming and labor-intensive. Summary of the invention

[0004] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0005] In the related art, the flue gas discharged from the coal-fired boiler is generally washed by a scrubber and then enters the adsorption tower. The carbon dioxide in the flue gas is adsorbed and removed by the organic amine in the adsorption tower. The saturated organic amine is transported to the regeneration tower for heating and decomposition regeneration. The decomposed and regenerated organic amine is returned to the absorption tower, and the decomposed carbon dioxide is captured for recycling. However, the organic amine solution is repeatedly used in high temperature and complex atmosphere conditions, and it is very easy to age and decompose, and produce impurities such as heat-stable salts, which seriously affect the stable operation of the carbon capture system.

[0006] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0007] To this end, an embodiment of the present invention provides a carbon capture pipe network ultrasonic cleaning system to solve the problem that pipe network blockage affects the stable operation of the carbon capture system.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] The carbon capture pipe network ultrasonic cleaning system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the carbon capture pipe network ultrasonic cleaning system of the embodiment of the present invention includes: an ultrasonic lithotripsy device and a supporting device.

[0030] The ultrasonic lithotripsy device comprises a sleeve 11, an ultrasonic lithotripsy rod 12 and a vibration probe 13. The ultrasonic lithotripsy rod 12 penetrates the sleeve 11 along the axial direction of the sleeve 11, and the sleeve 11 is used to place and guide the ultrasonic lithotripsy rod 12. The sleeve 11 provides a fixed channel for the ultrasonic lithotripsy rod 12, ensuring that the ultrasonic lithotripsy rod 12 can move in the correct direction and clean a specific position in the pipe network. The sleeve 11 covers the ultrasonic lithotripsy rod 12 to protect it from damage by the external environment (such as dust, moisture, corrosive gas, etc.), thereby extending the service life of the ultrasonic lithotripsy rod 12.

[0031] The vibration probe 13 is arranged at the left end of the ultrasonic lithotripsy rod 12. As a medium for energy transmission, it efficiently transmits ultrasonic energy from the main unit to the vibration probe 13 to ensure the cleaning effect. The vibration probe 13 is used to be close to the pipe to be cleaned. The ultrasonic vibration generated by it can effectively break the dehydration crystals and degradation products in the pipe network, thereby preventing the pipe network from being blocked.

[0032] The supporting device includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 is connected to the left end of the sleeve 11, and the second clamping member 22 is detachably connected to the first clamping member 21, so that the supporting device can be stably installed outside the carbon capture network for easy operation and maintenance.

[0033] Optionally, the first clamping member 21 and the second clamping member 22 are semi-annular so as to be adaptively clamped on the pipe to be cleaned, and the vibration probe 13 is located in the space defined by the first clamping member 21 and the second clamping member 22 for clamping the pipe so that the vibration probe 13 contacts the pipe.

[0034] Therefore, the carbon capture pipe network ultrasonic cleaning system of the embodiment of the present invention utilizes the ultrasonic lithotripsy effect outside the carbon capture pipe network to assist in efficient inspection, remove dehydration crystals, and degradation products to prevent blockage, while greatly reducing maintenance time and workload.

[0035] In some embodiments, Figure 1 As shown, the ultrasonic lithotripsy device further includes a frequency regulator 14 , which is connected to the second end of the ultrasonic lithotripsy rod 12 , and is used to adjust the working frequency of the ultrasonic lithotripsy rod 12 .

[0036] It is understandable that different pipe network materials and pollutant characteristics may require different frequencies of ultrasound to achieve the best cleaning effect. The frequency regulator 14 can adapt the working frequency of the ultrasonic lithotripsy rod to different cleaning requirements, thereby improving the cleaning efficiency. During the cleaning process, if it is found that pollutants in certain areas are difficult to break, the operator can adjust the frequency in real time to adapt to changes in the cleaning process, thereby improving the flexibility and efficiency of the cleaning operation.

[0037] In addition, the frequency of ultrasound directly affects the efficiency of its energy transfer in the medium. By adjusting the frequency, the propagation of ultrasound in the pipe network can be optimized, so that the energy acts on pollutants more effectively and reduces energy loss.

[0038] In some embodiments, Figure 1 As shown, the ultrasonic lithotripsy device further includes a handle 15 , which is connected to a frequency regulator 14 .

[0039] The handle 15 provides a user interface, allowing the operator to conveniently hold and control the ultrasonic lithotripsy device. Through the handle 15, the operator can accurately operate the ultrasonic lithotripsy rod 12 on site, including positioning, moving and adjusting.

[0040] Furthermore, the handle 15 is connected to the frequency regulator 14, so that the operator can adjust the working frequency of the ultrasonic lithotripsy rod 12 in real time through the control button or knob on the handle 15 to adapt to different cleaning requirements and characteristics of pollutants.

[0041] It should be noted that the design of the handle 15 is ergonomic, which can reduce the operator's hand fatigue during long-term use and improve the comfort and efficiency of operation.

[0042] In some embodiments, Figure 1 As shown, a power supply interface 16 is provided on the handle 15 so as to supply power to the ultrasonic lithotripsy device through the power supply interface 16 .

[0043] It is understandable that integrating the power supply interface 16 on the handle 15 helps reduce the interference of the power cord on the operation process, keeps the workplace clean and tidy, and the operator's freedom. The provision of the power supply interface 16 enables the ultrasonic lithotripsy device to be more conveniently connected to the power supply, and the interface design on the handle 15 allows the operator to quickly complete the assembly and power supply of the device in different working environments, thereby improving work efficiency.

[0044] Thus, the power supply interface 16 on the handle 15 helps to realize the modular design of the ultrasonic lithotripsy device, so that each component (such as the lithotripsy rod, the frequency regulator 14, the handle 15, etc.) can be replaced and maintained independently, and it is also convenient to upgrade and expand functions. In addition, the power supply interface 16 on the handle 15 usually has corresponding safety designs, such as built-in overload protection, leakage protection, etc. These designs can ensure the safety of the operator and the device.

[0045] In some embodiments, Figure 1 As shown, a vibration stabilizer is provided on the sleeve 11 , and the vibration stabilizer is located at the right end of the sleeve 11 .

[0046] The vibration stabilizer can effectively absorb and reduce the vibration generated by the ultrasonic lithotripsy rod 12 during operation and transmit it to the sleeve 11 and the supporting device, thereby reducing the impact on the entire system and its surrounding environment. Thus, by suppressing unnecessary vibration, the vibration stabilizer helps to reduce the risks that may arise during operation and improve the safety of operators.

[0047] In some embodiments, the first clamping member 21 and the second clamping member 22 are both provided with corresponding mounting holes, and the supporting device further includes an adjusting bolt 23 , which passes through the mounting holes of the first clamping member 21 and the mounting holes of the second clamping member 22 in sequence.

[0048] That is, the support device can be firmly fixed on the pipe to be cleaned in the carbon capture network through the mounting holes and the adjusting bolts 23, ensuring that the ultrasonic lithotripsy device will not shift during the cleaning process and maintain the correct position and direction.

[0049] It is understandable that the setting of the adjustment bolt 23 allows the operator to adjust the clamping force and position of the support device according to the size and shape of the pipeline to adapt to different pipe network conditions and cleaning requirements. By providing the adjustment bolt 23, the operator can easily adjust and optimize the working state of the ultrasonic lithotripsy device, thereby improving the cleaning efficiency and operating experience.

[0050] Furthermore, if Figure 1 As shown, the first clamping member 21 has a first lug 211 , and the mounting hole of the first clamping member 21 is located on the first lug 211 ; the second clamping member 22 has a second lug 221 , and the mounting hole of the second clamping member 22 is located on the second lug 221 .

[0051] It is understandable that the design of the lug increases the local structural strength of the clamp, making the area around the mounting hole stronger and able to withstand greater tightening force, thereby improving the overall stability of the support device. By setting the mounting hole on the lug, the tightening force can be more concentrated, which helps to improve the clamping effect of the clamp and ensure the stability of the device on the pipe network.

[0052] Optionally, the first lug 211 , the second lug 221 and the adjusting bolt 23 each have two corresponding ones, thereby improving the reliability and stability of the support device being clamped on the pipeline.

[0053] In some embodiments, the supporting device further includes a gasket 24 . The gasket 24 is sleeved on the adjusting bolt 23 . The gasket 24 is located between the first clamping member 21 and the second clamping member 22 .

[0054] By using gaskets 24 of different thicknesses, the distance between the first clamping member 21 and the second clamping member 22 can be adjusted to adapt to pipes of different diameters, ensuring that the supporting device can be firmly fixed on pipes of different sizes.

[0055] Specifically, there are multiple gaskets 24, and the thickness of the multiple gaskets 24 is different. One or more gaskets 24 are mounted on the adjusting bolt 23. By replacing the gaskets 24 of corresponding thickness, the distance between the first clamping member 21 and the second clamping member 22 can be adjusted. Therefore, the operator can select a suitable gasket 24 according to actual needs to achieve more accurate clamping force control.

[0056] The following describes a carbon capture pipe network ultrasonic cleaning method according to an embodiment of the present invention. The cleaning method is used in the carbon capture pipe network ultrasonic cleaning system in any of the above embodiments.

[0057] The carbon capture pipe network ultrasonic cleaning method of the embodiment of the present invention comprises:

[0058] Analyze the flow data of the carbon capture pipeline network to identify pipes that may be blocked in the pipeline network. Flow data can reflect the flow of fluids in the pipeline network. Abnormal flow data may indicate the accumulation of pollutants or blockage. For example, collect and monitor flow data in the pipeline network, and use data analysis technology to detect changes in flow patterns to determine which pipelines need to be cleaned.

[0059] Preferably, dehydrated crystals, high molecular weight degradation products and other pollutants are easily pumped into the heat exchanger in the heavy phase (carbon dioxide-rich solution) to heat the analysis pipeline to enrich the crystals, so this is chosen as the focus for vibration and gravel inspection.

[0060] Determine the location of pipelines to be cleaned in the carbon capture pipeline network, that is, determine which pipelines have the highest priority for cleaning and their specific locations based on the flow data analysis results. This includes field visits, sensor detection, or prediction by computational models to determine the pipelines to be cleaned.

[0061] The supporting device is clamped on the pipeline to be cleaned. Specifically, the first clamping member 21 and the second clamping member 22 are used, and the position and clamping force of the clamping device are adjusted by adjusting the bolt 23 and the gasket 24 to ensure that the device is firmly fixed on the pipeline.

[0062] The vibration probe 13 is adjusted to contact the outer peripheral wall of the pipe to be cleaned, ensuring that the vibration probe 13 can effectively transmit ultrasonic energy to the inside of the pipe to achieve a cleaning effect.

[0063] The ultrasonic lithotripsy device is activated, and the energy of ultrasound is used to break up pollutants in the pipe network, such as dehydration crystals and degradation products, to clean the pipes. The principle is to activate the ultrasonic lithotripsy device through the control device on the handle 15, and adjust the frequency regulator 14 to meet different cleaning requirements. The vibration generated by the ultrasonic lithotripsy rod 12 is transmitted to the vibration probe 13, thereby cleaning the pipe network.

[0064] Therefore, the implementation of the ultrasonic cleaning method for the entire carbon capture network aims to improve carbon capture efficiency, reduce system performance degradation caused by network blockage, and reduce maintenance costs and downtime. This method ensures the scientificity and effectiveness of the cleaning process through systematic analysis and operation steps.
