Description

Technical Field

[0001] The present invention relates to the field of carbon dioxide capture, and in particular to a dry regeneration separator. Background Art

[0002] In the field of carbon dioxide capture technology, the dry regeneration separator plays a key role in removing moisture and impurities from the captured carbon dioxide flow, thereby improving its purity and providing high-quality carbon dioxide for subsequent utilization or storage. The dry regeneration separator includes a separator body and an air inlet pipe and an air outlet pipe arranged on the separator body. The dry regeneration separator also includes a packing layer, a redistributor, a heater, a regeneration device, a heat exchanger, a controller and a discharge device arranged on the separator body.

[0003] The above-mentioned inlet pipe is the first contact point for flue gas to enter the equipment. Its design is crucial. It is necessary to ensure the uniformity of gas flow and prevent the gas from being over-concentrated or thinned in local areas, thereby affecting the drying effect. The packing layer is located inside the drying tower and is made of special porous medium materials. Its structural design is designed to maximize the gas-liquid contact area, thereby improving the drying efficiency. The redistributor is located above the packing layer and is responsible for evenly distributing the gas to each part of the packing layer to prevent channeling and ensure the uniformity and efficiency of the drying process. The heater provides the necessary heat energy for the packing or gas in the packing layer and accelerates the evaporation process of water. It is a key component to improve the drying efficiency. The packing in the packing layer is made of high-efficiency water-absorbing materials to capture moisture in the carbon dioxide gas flow and achieve the drying of the gas flow. The regeneration device includes a heating and cooling unit, which is used to make the packing in the packing layer release moisture after absorbing moisture and restore its drying capacity to ensure the recycling of the packing in the packing layer. After the packing in the packing layer is completely released, the heat exchanger cools it for the next round of drying cycle. The carbon dioxide gas flow after drying is discharged through the outlet pipe. The design takes into account the need to reduce pollutant emissions. The controller is an intelligent monitoring and regulation system that tracks operating parameters such as temperature, pressure, flow, etc. in real time to ensure that the equipment operates in the best condition. The discharge device is responsible for collecting and discharging the moisture released by the filler in the packing layer during the regeneration process to ensure the continuous and stable operation of the system.

[0004] However, the air inlet pipe is configured as a circular pipe, which easily generates eddy currents when the flue gas flows, resulting in a low separation efficiency of the drying and regeneration separator, thereby affecting the effect of the entire drying and regeneration process.

[0026] like Figures 1 to 3As shown, the present application provides a dry regeneration separator, and an embodiment of the dry regeneration separator includes: a separator body 10, a packing layer 21, a redistributor 22, a regeneration device, a heat exchanger, a discharge device 25 and a controller. An air inlet pipe 11 and an air outlet pipe 12 are provided on the separator body 10, and an exhaust port 23 is also provided on the separator body 10. The packing layer 21 is arranged in the separator body 10 and is located above the air inlet pipe 11. The redistributor 22 is arranged in the separator body 10 and is located above the packing layer 21. A heater is arranged above the redistributor 22 and is connected to the redistributor 22. The regeneration device includes a heat exchanger and a circulating pump connected to the heat exchanger, and the circulating pump is connected to the heater. The heat exchanger is arranged on one side of the separator body 10. The discharge device 25 is connected to the exhaust port 23. The redistributor 22, the heater, the heat exchanger, the circulation pump and the exhaust device 25 are all connected to the controller, and sensors are provided at the redistributor 22, the heater, the heat exchanger, the circulation pump and the exhaust device 25. A plurality of curved channels 13 are provided inside the air inlet pipe 11, and each curved channel 13 extends from bottom to top. The packing layer 21 is made of a corrugated plate made of ceramic or metal, which has a large specific surface area to provide sufficient gas-liquid contact area. The height and thickness of the packing layer 21 are optimized to adapt to a specific flue gas flow rate and an expected drying efficiency.

[0027] Applying the technical solution of this embodiment, the drying and regeneration separator includes: a separator body 10, a packing layer 21, a redistributor 22, a regeneration device, a heat exchanger, an exhaust device 25 and a controller. In the process of the flue gas entering the separator body 10 from the air inlet pipe 11, since each curved channel 13 extends from bottom to top, the gas flow path is increased, and the generation of eddy currents is effectively reduced, thereby improving the uniformity of the gas flow, improving the separation efficiency of the drying and regeneration separator, and thus ensuring the effect of the entire drying and regeneration process. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the air inlet pipe is set as a round pipe, which easily causes eddy currents to be generated when the flue gas flows.

[0028] like Figures 1 to 3 As shown, in order to reduce the resistance to smoke flow, each curved channel 13 includes a plurality of S-shaped segments, and two adjacent S-shaped segments are connected by a smooth transition segment.

[0029] like Figures 1 to 3 As shown, in order to adapt to a more uniform distribution of smoke, the cross-sectional shape of the air inlet pipe 11 is a trapezoid.

[0030] like Figures 1 to 3As shown, in order to effectively increase the gas flow path, each curved channel 13 is wavy or spiral, and the wavy or spiral curved channel setting makes the flow distance of the smoke in the air inlet pipe 11 at least 30% longer than the flow distance of the straight air inlet pipe. In order to optimize the smoke flow characteristics, the curvature radius of the curved channel 13 can be adjusted. In this way, the drying efficiency can be effectively improved, the energy consumption can be reduced, the equipment stability can be enhanced, and the maintenance work can be simplified. The curved channel 13 is a flexible part.

[0031] like Figures 1 to 3 As shown, a guide plate 14 is provided on the inner wall of each curved channel 13. When the smoke passes through the air inlet pipe, the guide plate guides the smoke in the curved channel 13 to flow smoothly, thereby achieving a more stable gas flow.

[0032] In other embodiments, a flow guiding protrusion or a flow guiding groove is provided on the inner wall of each curved channel 13 .

[0033] like Figures 1 to 3 As shown, the drying regeneration separator further includes a gas distribution chamber 15 disposed between the air inlet pipe 11 and the packing layer 21. The gas distribution chamber 15 prevents the flue gas from directly impacting the packing layer 21, thus achieving a buffering purpose and reducing the wear of the packing in the packing layer 21.

[0034] like Figures 1 to 3 As shown, in order to evenly disperse the smoke in the gas distribution chamber 15 , a plurality of distribution holes 151 are provided at equal intervals on the gas distribution chamber 15 .

[0035] like Figures 1 to 3 As shown, the air outlet pipe 12 is conical, which helps to reduce the emission of pollutants. A filter 24 is installed at the air outlet pipe 12. The filter 24 is further provided to remove the tiny particles that may be carried in the smoke discharged from the air outlet pipe 12.

[0036] like Figures 1 to 3 As shown, the drying and regeneration separator further includes a gas separation device connected to the gas outlet pipe 12. The gas separation device uses membrane separation or adsorption separation technology to further purify the dried carbon dioxide.

[0037] like Figures 1 to 3 As shown, the drying and regeneration separator also includes a screw compressor connected to the gas separation device. The screw compressor is used to compress the dried carbon dioxide to 20MPa for easy storage or transportation.

[0038] The above-mentioned redistributor 22 is arranged above the packing layer 21 and adopts a porous plate structure. The pore size and distribution are precisely calculated to ensure uniform rise of the flue gas in the packing layer 21 to avoid local oversaturation or insufficient drying.

[0039] The heater mentioned above adopts electric heating or steam heating, surrounds the packing layer 21 or is built in the packing layer 21, provides uniform heat distribution, and accelerates the absorption of moisture in the flue gas by the desiccant.

[0040] The filler in the packing layer 21 is a desiccant, and the desiccant is selected from high-performance silica gel or activated carbon, which has high water absorption and good thermal stability. After the desiccant absorbs water in the packing layer 21, it enters the regeneration device through the conveying device.

[0041] The heat exchanger uses water cooling or air cooling to cool the regenerated desiccant to a suitable temperature to ensure that it can maintain efficient drying performance when it enters the packing layer 21 again.

[0042] The above-mentioned controller adopts advanced PLC or DCS technology, monitors the temperature, pressure, flow rate and desiccant status of the flue gas in real time through sensors, and automatically adjusts the operation of the heater, circulation pump and heat exchanger to ensure stable operation of the system.

[0043] The above-mentioned discharge device 25 includes a discharge port 23 arranged at the bottom of the dryer and a discharge pipe connected to an external liquid storage tank. The discharge device 25 discharges the moisture released by the desiccant regularly or according to the instruction of the controller.

Its implementation effect is significantly improved. It can not only remove moisture from the gas, but also effectively adsorb and purify impurities to ensure the purity of the gas, thereby improving product quality and production efficiency.

[0046] Optimal combination of S-shaped segment and smooth transition segment

[0047] Furthermore, each curved channel 13 includes a plurality of S-shaped segments, and two adjacent S-shaped segments are connected by a smooth transition segment.

This design is particularly suitable for treating industrial waste gas containing a large amount of moisture and impurities, can significantly improve the efficiency of drying and regeneration, effectively reduce waste gas emissions in industrial production, reduce environmental pollution, and improve the recycling rate of resources.

[0048] Gas distribution optimization for trapezoidal cross sections

[0049] Furthermore, the cross-sectional shape of the air inlet pipe 11 is a trapezoid.

[0050] Mass transfer enhancement in wavy or spiral curved channels

[0051] Furthermore, each curved channel 13 is wavy or spiral, and the curvature radius of the curved channel 13 is adjustable. The wavy or spiral curved channel can increase the contact time between the gas and the packing layer, and improve the drying and regeneration effect. The adjustability of the curvature radius enables the equipment to adapt to the gas processing requirements of different flow rates and pressures, and is suitable for gas purification in the fields of petroleum refining, natural gas processing, etc. It can adjust the operating parameters according to different raw gas characteristics, optimize the drying and regeneration process, and improve the gas purification quality and the operating efficiency of the equipment.

[0052] Gas guiding effect of deflectors, protrusions and grooves

[0053] Furthermore, a guide plate 14 or a guide protrusion or a guide groove is provided on the inner wall of each curved channel 13. The guide plate, guide protrusion or guide groove can guide the gas flow, increase the contact area between the gas and the packing layer, and improve the drying and regeneration efficiency. This design can effectively remove water droplets and impurities in the steam when processing high-temperature and high-pressure steam. It is suitable for steam drying and purification in the power, chemical and other industries. It has a significant effect on improving the operating safety of the equipment and extending its service life. At the same time, it reduces the impurity content in the steam, improves the steam quality, and meets the needs of industrial production.

[0054] Uniform distribution effect of gas distribution chamber

[0055] Furthermore, the drying and regeneration separator also includes a gas distribution chamber 15 disposed between the air inlet pipe 11 and the packing layer 21.

This design can significantly improve the processing capacity and efficiency of the equipment when dealing with large-scale industrial gas purification projects, ensure stable drying and regeneration effects under high flow conditions, and is suitable for processing large-scale industrial gases, such as waste gas purification in the steel, cement and other industries, and helps achieve energy conservation and emission reduction goals.

[0056] Optimized distribution of evenly spaced holes

[0057] Furthermore, a plurality of distribution holes 151 are evenly spaced on the gas distribution chamber 15. The design of evenly spaced distribution holes can ensure that the gas is more evenly distributed in the packing layer, thereby improving the drying and regeneration effects. This design can effectively remove particles and harmful gases in the air and improve air quality when dealing with projects such as air purification and waste gas treatment. It is of great significance to improving the urban environment and protecting the health of residents, especially in areas with frequent haze weather, and can significantly improve air quality and enhance the quality of life of residents.

[0058] Double purification of conical outlet pipe and filter

[0059] Furthermore, the outlet pipe 12 is conical, and a filter 24 is installed at the outlet pipe 12. The conical outlet pipe can reduce the resistance of gas flow and improve the smoothness of gas flow, while the filter can further remove particles in the gas and improve the purity of the gas. This design can meet the strict requirements for gas purity when dealing with gas purification in high-precision manufacturing industries such as electronics and semiconductors, effectively prevent the influence of particles on the production line, ensure product quality, and at the same time, reduce equipment maintenance costs and improve the continuity and stability of the production line.

[0060] Advanced processing capabilities of gas separation devices

[0061] Furthermore, the dry regeneration separator also includes a gas separation device connected to the gas outlet pipe 12. The gas separation device can further separate different components in the gas, improve the purity and recycling rate of the gas. This design can effectively improve the utilization efficiency of resources and reduce environmental pollution when dealing with gas separation and recycling projects in the petroleum, chemical and other industries. Through deep processing, not only can valuable gas components be recovered, but also the raw material cost of the enterprise can be reduced, which promotes the development of the circular economy.

[0062] Efficient compression and storage of screw compressors

[0063] Furthermore, the dry regeneration separator also includes a screw compressor connected to the gas separation device. The screw compressor can compress the treated gas to facilitate the storage and transportation of the gas, and can also improve the efficiency of the gas separation device. This design can effectively improve the storage and transportation capacity of energy, reduce energy loss, and improve economic benefits when dealing with compression and storage projects of energy gases such as natural gas and petroleum gas. Especially in areas with tight energy supply and demand, it can significantly improve the stability and safety of energy supply and ensure the energy needs of industrial production and residents' lives.

[0064] Dual advantages of intelligent control and modular design

[0065] In addition, the drying and regeneration separator can also be equipped with an online monitoring system according to actual needs to monitor gas humidity, temperature, pressure, flow rate and other parameters in real time, and automatically adjust the operating status of the equipment through the controller to achieve intelligent control and improve the stability and reliability of the equipment. When dealing with industries such as medicine and food that have extremely high requirements for gas purity, this intelligent design can ensure the continuity and controllability of the gas treatment process, improve product quality and production efficiency.

[0066] Figures 1 to 3 The drying and regeneration separator includes a separator body 10, on which an air inlet pipe 11 and an air outlet pipe 12 are provided. A plurality of curved channels 13 are designed inside the air inlet pipe 11, and these curved channels 13 extend in a direction from bottom to top to increase the path and contact area of ​​gas flow and improve the drying efficiency. Each curved channel 13 is composed of a plurality of S-shaped segments, and two adjacent S-shaped segments are connected by a smooth transition segment. This design can ensure the smoothness of gas flow, reduce resistance, and increase the chance of gas contact with the packing layer 21. The cross-section of the air inlet pipe 11 is designed to be trapezoidal, which can better guide the gas into the packing layer 21 and improve the uniformity of gas distribution.

[0067] Figures 1 to 3 The position of the packing layer 21 is shown, which is arranged in the separator body 10 and is located above the air inlet pipe 11. The packing layer 21 is made of a specific material with high adsorption performance and is used to absorb moisture and impurities in the gas. Above the packing layer 21, a redistributor 22 is provided to further evenly distribute the gas, ensure that the gas can fully contact the packing layer 21, and improve the drying effect. The redistributor 22 is provided with a plurality of holes, and the gas will form a uniform airflow after passing through these holes, thereby improving the contact efficiency between the packing layer 21 and the gas.

[0068] Figures 1 to 3 In the embodiment, the heater is located above the redistributor 22 and is connected to the redistributor 22 through a pipeline. The function of the heater is to increase the gas temperature, thereby reducing the relative humidity of the gas and improving the drying effect. The regeneration device includes a heat exchanger and a circulation pump, which are connected to the heat exchanger and the heater to form a circulation system for heating the packing layer 21 to remove the adsorbed moisture and impurities and achieve the regeneration of the packing layer 21. The function of the heat exchanger is to recover the heat generated in the process of heating the packing layer 21, which is used to preheat the incoming gas and reduce energy consumption.

[0069] Figures 1 to 3 The position of the heat exchanger is shown, which is arranged on one side of the separator body 10. The heat exchanger is used to preheat the gas entering the separator to increase the gas drying speed. The exhaust device 25 is connected to the exhaust port 23 and is used to discharge the gas after the drying and regeneration process out of the separator. A sensor is provided at the exhaust port 23 to monitor the temperature, humidity and flow rate of the gas so that the controller can adjust the working state of the heater and the redistributor 22 in real time to ensure the best drying effect.

[0070] Figures 1 to 3 In the embodiment, the drying and regeneration separator further comprises a gas distribution chamber 15, which is located between the air inlet pipe 11 and the packing layer 21. The top of the gas distribution chamber 15 is provided with a plurality of equally spaced distribution holes 151, which are used to evenly distribute the gas entering from the air inlet pipe 11 to the packing layer 21, ensuring sufficient contact between the gas and the packing layer 21. The interior of the air inlet pipe 11 is provided with a guide plate 14, or a guide protrusion or a guide groove, which can guide the gas to flow along the curved channel 13, increase the residence time of the gas in the packing layer 21, and thus improve the drying efficiency.

[0071] Figures 1 to 3 The shape of the outlet pipe 12 is shown, which is designed to be conical. This shape can accelerate the discharge of gas, reduce the residence time of gas in the outlet pipe 12, and improve the processing efficiency. A filter 24 is installed at the outlet pipe 12 to further purify the gas and remove possible residual impurities. The drying regeneration separator also includes a gas separation device, which is connected to the outlet pipe 12 and is used to separate the dried gas from the water vapor generated during the regeneration process. In addition, the drying regeneration separator is also equipped with a screw compressor, which is connected to the gas separation device and is used to compress the dried gas for storage or further processing of the gas.

[0072] Figures 1 to 3The connection of the controller is described in detail. The controller is connected to the redistributor 22, the heater, the heat exchanger, the circulation pump and the exhaust device 25, and can monitor the working state of the entire system. By receiving sensor data from each component, the operating parameters of each component are adjusted to achieve the optimal operation of the system. The sensor is used to monitor key parameters such as temperature, humidity, gas flow rate and the adsorption capacity of the packing layer 21 to ensure that the system operates in the best state, improve the drying and regeneration efficiency, and reduce energy consumption.

[0073] Figures 1 to 3 An optional technical solution is shown, in which the shape of each curved channel 13 can be selected to be wavy or spiral, and the radius of curvature of the curved channel 13 is designed to be adjustable. This design increases the complexity of gas flow, increases the contact area between the gas and the packing layer 21, and thus improves the drying efficiency. In addition, the adjustability of the radius of curvature enables the system to adapt to different gas flow and pressure conditions, and improves the flexibility and adaptability of the system. A guide plate 14, or a guide protrusion or a guide groove is provided on the inner wall of each curved channel 13. These guide devices can guide the gas to flow more effectively along the curved channel 13, increase the residence time of the gas in the packing layer 21, thereby improving the drying efficiency and the use effect of the packing layer 21.

[0074] Through the above technical solution, the drying and regeneration separator can efficiently dry the gas and realize the regeneration of the packing layer 21, thereby avoiding the frequent replacement of the packing layer 21 and reducing the operating cost. The flexibility and intelligent control of the system enable it to adapt to the gas drying needs under different conditions, improve the drying efficiency, reduce energy consumption, and have significant economic and environmental benefits.

[0075] Figures 1 to 3 In the figure, you can see the air flow path of the drying and regeneration separator when it is working. The gas enters from the air inlet pipe 11, contacts the packing layer 21 through the curved channel 13, and is initially dried. Subsequently, the gas is evenly distributed by the redistributor 22 and enters the heater for heating to improve the drying effect. The heated gas passes through the heat exchanger and circulation pump of the regeneration device to achieve the regeneration of the packing layer 21, and at the same time recovers heat to preheat the newly entered gas. After the gas is regenerated by the packing layer 21, it enters the gas distribution chamber 15, is evenly distributed through the distribution holes 151, and contacts the packing layer 21 again, further improving the drying efficiency. Finally, the gas is discharged through the outlet pipe 12 and purified by the filter 24 to ensure the cleanliness of the gas. During the whole process, the controller monitors the sensor data in real time, adjusts the working status of each component, and realizes the optimal operation of the system.

[0076] The working principle of the drying and regeneration separator of this embodiment is as follows:

[0077] The captured flue gas is introduced into the dryer through the air inlet pipe. The air inlet pipe is designed with multiple curved sections, which reduces the linear speed of the flue gas flow and reduces the generation of vortices. The end of the air inlet pipe is connected to a gas distribution chamber with multiple small holes to ensure that the flue gas is evenly distributed before entering the packing layer. The packing layer is made of high-efficiency ceramic or carbon steel materials with a large specific surface area, which promotes the contact between gas and liquid and improves the adsorption efficiency of moisture. The redistributor is designed to be adjustable to meet the gas distribution requirements under different operating conditions and ensure the uniform flow of gas in the packing layer. The heater uses an external circulating hot fluid to transfer heat through the heat exchange plate under the packing layer to evenly heat the desiccant and accelerate the evaporation of moisture. The desiccant adsorbed with moisture is sent to the regeneration system through a conveying device, and after heating to remove moisture, it is cooled through a heat exchanger and recirculated to the packing layer. The dried carbon dioxide is discharged through the outlet pipe, and a filter is set at the outlet pipe to remove dust or droplets that may be carried. The controller integrates multiple sensors and actuators to achieve real-time monitoring and intelligent adjustment of parameters such as temperature, pressure, and flow. The exhaust device regularly discharges the water released from the desiccant and transfers it to the liquid storage tank through a pump, or directly discharges it to the wastewater treatment system. The gas separation device uses membrane separation or molecular sieve adsorption technology to further improve the purity of carbon dioxide. After that, the screw compressor compresses the gas to high pressure for easy storage or transportation.

[0078] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
