Description

Technical Field

[0001] This utility model relates to the field of water oxygenation technology, and in particular to a carbon removal device and water oxygenation system suitable for oxygenation of air-medium water supply. Background Technology

[0002] Oxygenation treatment of feedwater is the primary feedwater treatment process for ultra-supercritical pressure thermal power units. It can effectively inhibit the flow-accelerated corrosion of the feedwater system and high-pressure heater drainage system. It also reduces the generation and migration of corrosion products in the thermal system, lowers the scaling rate of boiler heating surfaces, prevents scaling and salt accumulation in the turbine, extends the fine treatment operation cycle, reduces the frequency of fine treatment resin regeneration, acid and alkali consumption, and waste liquid volume, and improves the safety and economy of unit operation, resulting in significant energy-saving and consumption-reducing effects.

[0003] Currently, with the continuous development and improvement of water supply oxygenation technology, different technical approaches have emerged. These can be categorized by the water supply control range into high-oxygen, low-oxygen, and very low-oxygen control technologies; by the oxygenation point, into single-point, two-point, and three-point technologies; and by the oxygenation medium, into pure oxygen, air, and liquid oxygen (oxygen-enriched water).

[0004] Currently, using air as the oxygenation medium eliminates the need to replace oxygen cylinders, achieving largely automated and precise oxygenation, unattended operation, and a high safety factor, making it the fastest-growing technology in recent years. However, air generally contains carbon dioxide, which, when introduced into the water-steam system along with the oxygenation medium, may lower the pH value of the feedwater, thereby posing a risk of corrosion to thermal equipment. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a carbon removal device suitable for oxygenating water supply systems using air as the medium.

[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figure 1 Describes a carbon removal device 10 suitable for oxygenation of air-medium water supply according to a first aspect embodiment of the present invention.

[0028] like Figure 1 As shown, the carbon removal device 10 for oxygenation of water using air medium according to an embodiment of the present invention includes: an air inlet pipe 11, a carbon remover 12, an air outlet pipe 13, an empty container 14, an empty pipe 15, and a connecting pipe 16. The air inlet end of the air inlet pipe 11 is adapted to be connected to a compressed air source; the air outlet end of the air inlet pipe 11 is connected to the air inlet of the carbon remover 12, which is used to remove carbon dioxide from the compressed air; the air inlet end of the air outlet pipe 13 is connected to the air outlet of the carbon remover 12; a cavity 141 is formed inside the empty container 14, and the air outlet end of the air outlet pipe 13 extends into the cavity 141 and is arranged in the upper part of the cavity 141; the empty pipe 15 is connected to the empty container 14, and the air inlet end of the empty pipe 15 is located at the bottom of the cavity 141; the air inlet end of the connecting pipe 16 extends into the cavity 141, and the air outlet end of the connecting pipe 16 is adapted to be connected to an air compressor 20.

[0029] The intake pipe 11 is mainly used to supply compressed air to the decarbonizer 12; the decarbonizer 12 is mainly used to remove carbon dioxide from the compressed air; the exhaust pipe 13 is mainly used to transport the compressed air after carbon dioxide removal to the vent container 14; the vent container 14 has a cavity 141 inside, which can be used to temporarily store the compressed air after carbon dioxide removal; the vent pipe 15 is mainly used to connect the vent container 14 to the outside, and can be used to discharge the gas in the vent container 14 that has not passed through the decarbonizer 12; the connecting pipe 16 is mainly used to connect the cavity 141 to the air compressor 20, and is used to transport the compressed air after carbon dioxide removal to the air compressor 20.

[0030] The statement that "the outlet end of the exhaust pipe 13 is located at the upper part of the cavity 141" indicates that the treated air enters the venting container 14 from the upper part of the cavity 141. The statement that "the inlet end of the vent pipe 15 is located at the bottom of the cavity 141" indicates that when the venting container 14 exhausts air, the air at the bottom is discharged first; that is, the venting container 14 exhausts air from the bottom outwards. Therefore, it can be understood that when the decarbonization device 10 starts working, the gas treated by the decarbonizer 12 enters the upper part of the container through the exhaust pipe 13. Due to gas diffusion, the treated gas will push the untreated gas downwards from the top, thereby venting the gas that has not passed through the decarbonizer 12. It should be noted that the gas treated by the decarbonizer 12 still maintains a slightly positive pressure state, which further ensures the venting of the venting container 14.

[0031] When the water oxygenation system 100 is working, the decarbonization device 10 is turned on first. At this time, compressed air is supplied to the decarbonizer 12 with a certain pressure through the air inlet pipe 11. The air after being processed by the decarbonizer 12 enters the vent container 14 to vent the untreated gas in the vent container 14. Then the air compressor 20 is turned on. The air compressor 20 absorbs the air after being processed by the decarbonizer 12 that is temporarily stored in the vent container 14 through the connecting pipe 16.

[0032] Additionally, it should be noted that the vent pipe 15 mainly connects the cavity 141 to the outside, meaning that the vent container 14 is always in an open state. In this way, when the decarbonator 12 is damaged and cannot supply air to the air compressor 20, the air compressor 20 can still directly draw in air through the vent pipe, ensuring the normal operation of the subsequent water supply oxygenation equipment 30.

[0033] According to the present invention, the carbon removal device 10 for oxygenation of air-medium water supply can remove carbon dioxide from the air by setting a carbon remover 12, thereby reducing the risk of thermal system corrosion caused by the water supply oxygenation system 100; by setting an venting container 14, the carbon dioxide content in the water supply oxygenation system 100 can be further reduced, thereby further reducing the risk of thermal system corrosion caused by the water supply oxygenation system 100; at the same time, it can still ensure the normal operation of the water supply oxygenation system 100 when the carbon remover 12 is damaged, thereby ensuring the normal operation of the thermal system.

[0034] According to some embodiments of this utility model, such as Figure 1 As shown, a through hole is formed at the bottom of the vent container 14, and the air inlet end of the vent pipe 15 is connected to the periphery of the through hole. It can be understood that the opening of the vent container 14 is arranged at the bottom, which facilitates the discharge of untreated air from the vent container 14 and reduces the risk of carbon dioxide seepage and debris falling into the system during shutdown.

[0035] According to some embodiments of this utility model, such as Figure 1 As shown, the air inlet of the connecting pipe 16 is located at the upper part of the cavity 141. This ensures the cleanliness of the air entering the air compressor 20, thereby further reducing the probability of corrosion in the thermal system.

[0036] According to some embodiments of this utility model, such as Figure 1 As shown, there are multiple connecting pipes 16, with their air inlet ends spaced apart in the upper part of the cavity 141. For example, there can be two, three, or more connecting pipes 16. It should be noted that the number of connecting pipes 16 corresponds one-to-one with the number of air compressors 20, which facilitates switching of air compressors 20 and thus benefits the maintenance of air compressors 20.

[0037] According to some embodiments of this utility model, the decarbonizer 12 includes a timing device and an alarm device. The timing device is used to record the operating time of the decarbonizer 12; the alarm device is configured to issue an alarm signal when the operating time exceeds a preset time and / or when the decarbonizer 12 malfunctions. It is understood that the alarm device can issue an alarm signal when the operating time exceeds the preset time, where the preset time is the maximum cumulative operating time of the product, i.e., the service life of the internal filter 173 and adsorption membrane of the decarbonizer 12. In other words, the alarm device can automatically issue an alarm signal when a component reaches its maximum service life. This allows operators to replace and maintain the decarbonizer 12 in a timely manner, thereby ensuring the decarbonization effect of the decarbonization system. The alarm device can also issue an alarm signal when the decarbonizer 12 malfunctions, allowing operators to quickly assess the situation and take appropriate action, thereby reducing greater losses caused by untimely fault handling.

[0038] According to some embodiments of this utility model, the carbon remover 12 includes: multiple adsorption cylinders filled with adsorbent for adsorbing carbon dioxide. It is understood that the carbon remover 12 uses pressure swing adsorption (PSA) technology to remove carbon dioxide from the air. PSA has a high removal rate and can provide clean and dry gas with a total carbon dioxide content of less than 1 ppm. This further reduces the risk of thermal system corrosion caused by oxygenation of the air medium.

[0039] According to some embodiments of this utility model, such as Figure 1As shown, the decarbonization device 10 also includes an isolation valve 171 and a solenoid valve 172. The isolation valve 171 is connected in series with the intake pipe 11 to control the opening and closing of the intake pipe 11. The solenoid valve 172 is connected in series with the intake pipe 11 and is arranged between the isolation valve 171 and the decarbonizer 12. The isolation valve 171 is electrically connected to the decarbonizer 12. Specifically, the isolation valve 171 is mainly used to disconnect the gas supply when the decarbonizer 12 is under maintenance, so as to facilitate the maintenance of the decarbonizer 12. It should be noted that the isolation valve 171 is normally open during operation. The solenoid valve 172 is electrically connected to the decarbonizer 12 to achieve synchronization with the start and stop of the decarbonizer 12. In this way, when the decarbonizer 12 is not working, the intake pipe 11 can be closed synchronously, thereby avoiding unnecessary gas consumption and possible system pollution or efficiency reduction.

[0040] According to some embodiments of this utility model, such as Figure 1 As shown, the decarbonization device 10 also includes a filter 173, which is connected in series with the air inlet pipe 11. The filter 173 can remove impurities and moisture from the air, thereby protecting key components such as the downstream decarbonizer 12, air compressor 20, various valves, and flow meter 174, thus preventing component failure during operation and ensuring the normal operation of the entire device.

[0041] Optionally, filter 173 can be one or more of a 0.01μm coagulation filter 173 or an activated carbon filter 173 as a pre-filter 173. The 0.01μm coagulation filter 173 has high filtration performance, capable of removing particles as small as 0.01 micrometers; the activated carbon filter 173 has strong adsorption capacity, capable of adsorbing various impurities. Therefore, using one or more of a 0.01μm coagulation filter 173 or an activated carbon filter 173 as a pre-filter can further improve the filtration effect of filter 173.

[0042] According to some embodiments of this utility model, such as Figure 1As shown, the carbon removal device 10 also includes a flow meter 174 and a throttle valve 175. The flow meter 174 is connected in series on the outlet pipe 13 and is used to detect the outlet flow of the carbon remover 12. The throttle valve 175 is connected in series on the outlet pipe 13 and is located between the flow meter 174 and the venting container 14. The throttle valve 175 is electrically connected to the flow meter 174. A flow meter 174 is connected in series on the outlet pipe 13 to better determine whether the decarbonizer 12 is working properly. This allows operators to quickly assess the situation and take appropriate action, reducing potential losses due to delayed troubleshooting. It also allows for more direct observation of the actual outlet flow of the decarbonizer 12, enabling operators to adjust subsequent valve openings to meet the needs of the air compressor 20. A throttle valve 175 controls the flow dimensions within the outlet pipe 13, thereby controlling the outlet flow rate. This ensures the outlet volume meets the requirements of the air compressor 20 while preventing incomplete decarbonization due to excessive flow, further improving the decarbonization effect of the decarbonizer 12.

[0043] The water oxygenation system 100 according to the second aspect of the present invention includes: an air compressor 20, a water oxygenation device 30, and a carbon removal device 10 suitable for oxygenation of water using air medium according to the first aspect of the present invention. The air inlet of the air compressor 20 is connected to the cavity 141 through a connecting pipe 16, and the air outlet of the air compressor 20 is connected to the water oxygenation device 30.

[0044] Among them, air compressor 20 is mainly used to repressurize the decarbonized air to meet the pressure requirements of water supply oxygenation equipment 30. It should be noted that there can be multiple air compressors 20, for example... Figure 1 As shown, there are two air compressors 20, and each air compressor 20 is connected to the venting container 14 through two connecting pipes 16. In this way, if one air compressor 20 fails, the other air compressor 20 can be started, thus ensuring the safe and stable operation of the unit.

[0045] The water oxygenation system 100 of this utility model improves the overall performance of the water oxygenation system 100 by providing the carbon removal device 10 of the first aspect embodiment described above.

[0046] The following will refer to Figure 1 This application describes a water oxygenation system 100 according to a specific embodiment.

[0047] Reference Figure 1 The water supply oxygenation system 100 includes: an air compressor 20, a water supply oxygenation device 30, and a carbon removal device 10. The carbon removal device 10 includes: an air inlet pipe 11, a carbon remover 12, an air outlet pipe 13, an air venting container 14, an air venting pipe 15, and a connecting pipe 16. The air compressor 20 has a maximum air intake capacity of 100 L / min.

[0048] Specifically, the water supply oxygenation system 100 uses compressed air from the power plant as its air source, with a pressure of 0.6 MPa and an air supply rate greater than 200 L / min. The air source is connected to the decarbonator 12 via an air inlet pipe 11, which is a 1 / 2-inch diameter stainless steel pipe suitable for the decarbonator 12.

[0049] The carbon remover 12 uses pressure swing adsorption technology to remove carbon dioxide from the air. The carbon remover 12 includes multiple adsorption cylinders filled with adsorbent, which is used to adsorb carbon dioxide.

[0050] In addition, the decarbonizer 12 also includes a timing device and an alarm device. The timing device is used to record the running time of the decarbonizer 12. The alarm device is configured to issue an alarm signal when the running time exceeds a preset time and / or when the decarbonizer 12 malfunctions.

[0051] The exhaust pipe is mainly used to transport the gas treated by the decarbonizer 12 to the vent container 14.

[0052] The vent container 14 is mainly used for temporary storage of gas treated by the decarbonizer 12. The vent container 14 has a volume of approximately 5L, and its bottom has a vent port and a vent pipe 15 connected to the vent port. An internal cavity 141 is formed, and the outlet end of the exhaust pipe 13 extends into the cavity 141 and is located at the upper part of the cavity 141. Furthermore, the vent pipe 15 has a length greater than 20cm and a diameter of 1 / 2 inch.

[0053] The connecting pipe 16 is mainly used to connect the venting container 14 and the air compressor 20 to provide processed gas to the air compressor 20.

[0054] Furthermore, the decarbonization device 10 also includes: an isolation valve 171, a solenoid valve 172, and a filter 173 connected in series on the intake pipe 11. The isolation valve 171 is connected in series on the intake pipe 11 to control the opening and closing of the intake pipe 11; the solenoid valve 172 is connected in series on the intake pipe 11 and is arranged between the isolation valve 171 and the decarbonizer 12, and the isolation valve 171 is electrically connected to the decarbonizer 12; the filter 173 is connected between the solenoid valve 172 and the decarbonizer 12 to filter impurities in the air.

[0055] The decarbonization device 10 also includes a flow meter 174 and a throttle valve 175 connected in series on the outlet pipe 13. The flow meter 174 is used to detect the outlet flow of the decarbonizer 12. The throttle valve 175 is connected in series on the outlet pipe 13 and is located between the flow meter 174 and the venting container 14 to control the outlet flow of the decarbonizer 12 to about 120 L / min.

[0056] When the water oxygenation system 100 is working, the decarbonization device 10 is turned on first. At this time, compressed air is supplied to the decarbonizer 12 with a certain pressure through the air inlet pipe 11. The air after being processed by the decarbonizer 12 enters the vent container 14 to vent the untreated gas in the vent container 14. Then the air compressor 20 is turned on. The air compressor 20 absorbs the air after being processed by the decarbonizer 12 that is temporarily stored in the vent container 14 through the connecting pipe 16.

[0057] According to the present invention, the carbon removal device 10 for oxygenation of air-medium water supply can remove carbon dioxide from the air by setting a carbon remover 12, thereby reducing the risk of thermal system corrosion caused by the water supply oxygenation system 100; by setting an venting container 14, the carbon dioxide content in the water supply oxygenation system 100 can be further reduced, thereby further reducing the risk of thermal system corrosion caused by the water supply oxygenation system 100; at the same time, it can still ensure the normal operation of the water supply oxygenation system 100 when the carbon remover 12 is damaged, thereby ensuring the normal operation of the thermal system.
