Description

Technical Field

[0001] This invention relates to the field of capture tower technology, specifically to a high-efficiency carbon dioxide capture tower. Background Technology

[0002] As a tower-type purification device that relies on an aqueous medium to remove useless components and solid dust particles from gases and also has a cooling function, the water scrubbing tower plays a key role in flue gas purification in the carbon dioxide capture process. It can perform deep cleaning on the captured carbon dioxide flue gas, effectively removing harmful impurities in the flue gas to achieve gas purification standards. During operation, multiple sets of spray heads spray the cleaning liquid at high pressure. The atomized micro-droplets will fully collide and adsorb with the dust particles in the flue gas, causing the dust particles to continuously agglomerate and increase in weight. Finally, under the action of gravity, they settle to the bottom water tank and flow into the circulating liquid for recycling. However, traditional water scrubbing towers generally have obvious defects: the spray nozzles are all fixedly installed and remain stationary relative to the gas flow field, resulting in limited and uneven spray coverage, causing a significant difference in dust removal and purification effect between areas near the nozzles and areas far from the nozzles; at the same time, because the cleaning fluid is recycled in a closed loop, the impurities remaining in the recycled liquid can easily interfere with the stability of the circulating pump, causing hydraulic fluctuations at the nozzle outlet, which in turn leads to uneven atomization and different droplet sizes, further reducing the overall flue gas purification efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a high-efficiency carbon dioxide capture tower. It utilizes a cylindrical filter screen to filter and guide the cleaning liquid and solid impurities, allowing the cleaning liquid to be recycled. Furthermore, the atomizing nozzle rotates to increase the effective contact area between the water mist and the dust-laden gas. Additionally, an elastic gas film is positioned in front of the atomizing nozzle to buffer the cleaning liquid during its flow, providing necessary liquid pressure stabilization and thus improving the cleaning effect on dust particles.

[0014] Compared with the prior art, the present invention provides a high-efficiency carbon dioxide capture tower, which has the following beneficial effects:

[0015] 1. The cylindrical filter screen filters and guides the cleaning liquid and solid impurities, allowing the cleaning liquid to be recycled. The atomizing nozzle rotates to increase the effective contact area between the water mist and the dust-laden gas. Furthermore, the atomizing nozzle has an elastic air film in front to buffer the cleaning liquid during its flow, providing necessary liquid pressure stabilization and thus improving the cleaning effect on dust particles.

[0016] 2. Equipped with a filter-type flow guiding mechanism, the core structure consists of a bottom hollow vessel, a vertical hollow vessel, a vertical filter cartridge, and a dual-output shaft motor. The vertical filter cartridge achieves three-phase separation of gas, liquid, and solid, allowing the cleaning liquid to be recycled and solid impurities to be collected centrally. Combined with air intake, exhaust, liquid discharge, and bottom sewage discharge channels, it achieves orderly fluid flow guiding, ensuring stable flow and efficient purification of dust-laden carbon dioxide, while separating and intercepting dust to prevent clogging. At the same time, it provides a stable installation foundation for the dual-output shaft motor, supporting the synchronous operation of the spray and sewage discharge mechanisms. The overall structure is compact, with efficient flow guiding, reliable filtration, and the ability to achieve liquid circulation and directional discharge of impurities.

[0017] 3. Equipped with a buffered driven spray mechanism, relying on a hollow turntable, atomizing nozzles, elastic air film, conical body, and curved liquid inlet channel, the hollow turntable is rotated by a dual-output shaft motor, allowing the atomizing nozzles to revolve and spray, significantly increasing the contact area between the water mist and the dust-laden gas. At the same time, the elastic air film inside the conical body can buffer and stabilize the pressure of the cleaning liquid, avoiding unstable spray caused by hydraulic fluctuations. The curved liquid inlet channel and the liquid flow channel are sealed together by bearings, ensuring stable liquid delivery without hindering the rotation of the turntable. The whole system achieves dynamic and uniform spray, stable pressure output, and efficient gas-liquid contact, significantly improving the dust removal and purification effect of carbon dioxide gas.

[0018] 4. Equipped with a spiral discharge mechanism, the core structure consists of a screw, a movable contact plate, a limiting rod, and a spiral spring. Driven synchronously by a dual-shaft motor, the screw can push solid impurities in the vertical filter cartridge downwards and collect them. The limiting rod restricts the movable contact plate to move only longitudinally, and the compressed spiral spring provides elastic damping. When the impurities accumulate to the set pressure, the filter cartridge is automatically opened for discharge, and when the pressure decreases, it automatically closes to seal. This not only efficiently discharges dust and impurities and prevents filter cartridge clogging, but also effectively prevents cleaning liquid leakage. Continuous automatic discharge can be achieved without stopping the machine. The structure is simple and reliable, the operation is stable, and maintenance is convenient. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 and Figure 2 A high-efficiency carbon dioxide capture tower, wherein during equipment installation, the drain channel 16 is connected to the inlet of a liquid circulation pump via a pipe, the curved inlet channel 27 is connected to the outlet of the liquid circulation pump via a pipe, and the air inlet channel 17 is connected to a device that emits carbon dioxide gas.

[0030] To guide the filtration of impurities in the gas, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A filter-type flow guiding mechanism 1 needs to be set up. Its structure includes a bottom hollow vessel 11 that can store cleaning liquid and has a hollow internal structure, a vertical hollow vessel 13 located at the top center of the bottom hollow vessel 11 and has a hollow internal structure, a vertical filter cylinder 110 installed at the boundary between the bottom hollow vessel 11 and the vertical hollow vessel 13 and capable of filtering the gas, and a dual-output shaft motor 113 installed at the center of the vertical hollow vessel 13 and capable of driving the components to rotate. The carbon dioxide mixed gas containing dust impurities is stably sent into the gas dust removal chamber 15 in the tower through the air inlet channel 17. In the chamber, it comes into full contact with the atomized spray purification liquid. After the droplets adsorb the dust, they form dust-laden droplets and naturally settle into the vertical filter cylinder 110 below under their own gravity. The clean gas that has completed dust removal and purification flows upward and is smoothly discharged through the top exhaust channel 18. At the same time, after the dust-laden liquid enters the vertical filter cartridge 110, solid-liquid separation is achieved. The clean cleaning liquid flows through the filter holes to the surrounding area of ​​the bottom liquid storage chamber 14, while solid dust impurities are intercepted and collected inside the filter cartridge. The filtered clean liquid is pressurized by the liquid circulation pump and transported to the curved liquid inlet channel 27 to re-participate in the atomization dust removal operation, thereby forming a continuous and stable gas-liquid-solid three-phase separation and fluid filtration and guiding circulation.

[0031] For details regarding the specific structure of the filter-type flow guiding mechanism 1, please refer to [link / reference]. Figure 3 and Figure 4 The device is equipped with support legs 12 installed on the bottom edge of the bottom hollow vessel 11, providing stable support for the entire device. A vertical hollow vessel 13 is integrally formed at the center of the upper surface of the bottom hollow vessel 11, with a compact structure and strong sealing. Inside the vertical hollow vessel 13 is a bottom liquid storage chamber 14 for storing cleaning liquid. The interior of the vertical hollow vessel 13 is a gas dust removal chamber 15 connected to the bottom liquid storage chamber 14, providing a dedicated space for gas-liquid contact dust removal. A drain channel 16 connected to the bottom liquid storage chamber 14 is opened on the side of the bottom hollow vessel 11 to achieve stable output of the cleaning liquid. An air inlet channel 17 connected to the bottom area of ​​the gas dust removal chamber 15 is provided on the bottom side of the vertical hollow vessel 13 for uniformly feeding the dust-laden carbon dioxide gas to be treated. Its top is connected to... The exhaust channel 18 at the top of the gas dust removal chamber 15 ensures smooth discharge of purified gas. A channel installation hole 19 connected to the gas dust removal chamber 15 is also reserved on one side of the exhaust channel 18 for the fixed installation of supporting pipelines. A vertical filter cartridge 110 is installed at the center of the bottom hollow vessel 11 and directly below the vertical hollow vessel 13 to achieve efficient solid-liquid separation. A bottom sewage discharge channel 111 connected to the vertical filter cartridge 110 is opened at the center of the bottom end of the bottom hollow vessel 11 for the discharge of separated solid impurities. In addition, a dual-shaft motor 113 is longitudinally installed in the middle of the vertical hollow vessel 13 through a hollow fixing frame 112. The motor adopts a structure in which the two ends of the single rotor shaft extend out of the housing, and can simultaneously and independently drive the front and rear loads, providing stable power for the spraying and sewage discharge mechanism.

[0032] To achieve stable and wide-area atomization dust suppression, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 and Figure 6 A buffered driven spray mechanism 2 needs to be set up. Its structure includes a hollow turntable 21 placed at the center of the bottom hollow vessel 11 and rotating with the dual-output shaft motor 113; atomizing nozzles 210 installed on the circumference of the hollow turntable 21 and capable of discharging the cleaning liquid in atomized form to the surrounding area; and an elastic air film 29 installed on the top of the hollow turntable 21 and capable of buffering the liquid. The cleaning liquid is delivered by the liquid circulation pump and flows smoothly into the liquid reserved cavity 24 along the curved liquid inlet channel 27. After being stabilized and buffered in the cavity, it is evenly distributed to each atomizing nozzle 210 and continuously sprayed in the form of fine atomized particles to the surrounding area. The atomized droplets come into full contact with dust particles in the rising airflow, relying on physical adsorption to capture the dust, forming dust-laden droplets that settle downwards under gravity, achieving efficient adsorption and cleaning of dust impurities in carbon dioxide gas. After starting the dual-shaft motor 113, the motor rotor synchronously drives the hollow turntable 21 to rotate at a uniform speed, causing the circumferentially distributed atomizing nozzles 210 to revolve together. The sprayed atomized droplets form a spiral downward spray trajectory, which not only greatly expands the contact coverage of the atomized liquid and the dust-laden gas, but also enhances the dynamic contact and mixing effect of the gas and liquid phases, significantly improving the overall dust removal efficiency.

[0033] For details regarding the specific structure of the buffer-driven spray mechanism 2, please refer to [link / reference]. Figure 5 and Figure 6The mechanism features an integrally formed docking plate 22 at the bottom center of the hollow turntable 21, which is used to securely connect to the top of the rotor of the dual-output shaft motor 113, ensuring reliable power transmission. The top of the hollow turntable 21 has a conical body 23, whose bottom matches the size of the docking plate 22 and gradually narrows upwards, effectively guiding the airflow upwards smoothly and reducing airflow resistance and turbulence. The hollow turntable 21 has a liquid pre-reserved cavity 24, and the conical body 23 has a conical buffer cavity 25. These two are connected by multiple component insertion ports 28. Each component insertion port 28 is sealed with an elastic gas membrane 29 made of highly elastic sealing rubber, which can elastically expand and contract with changes in liquid pressure, achieving liquid buffering and pressure stability, and preventing uneven atomization due to pressure fluctuations. A liquid flow channel 26 is provided at the center of the conical body 23, which runs through the conical buffer cavity 25. Its top end is connected to the outside and its bottom end is connected to the liquid reserved cavity 24, ensuring stable and smooth delivery of cleaning liquid. The top end of the liquid flow channel 26 is equipped with a relatively rotatable curved liquid inlet channel 27 through a combination structure of bearing and sealing ring. The middle part of the channel is fixedly installed in the channel mounting hole 19, which ensures both sealed liquid delivery and does not interfere with the normal rotation of the hollow turntable 21. Multiple atomizing nozzles 210 are evenly arranged on the circumference of the hollow turntable 21, which can spray the liquid in an atomized state to all directions efficiently. At the same time, a reasonable airflow gap is reserved between the outer circumference of the first docking plate 22 and the inner wall of the gas dust removal cavity 15 to ensure the smooth passage of dust-containing carbon dioxide gas and improve gas-liquid contact and dust removal effect.

[0034] To achieve timely emission of particulate matter, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8A spiral sewage discharge mechanism 3 needs to be installed. Its structure includes a screw 31 placed in the vertical filter cylinder 110 and rotating with the dual-shaft motor 113, a movable contact plate 33 that abuts against the bottom of the bottom sewage discharge channel 111 and can move longitudinally, a limiting rod 35 that can limit the movable contact plate 33 to move only longitudinally, and a spiral spring 38 that can produce an elastic damping effect on the downward movement of the movable contact plate 33. The screw 31, which rotates synchronously with the dual-shaft motor 113, can generate a directional downward pushing force on the dust particles trapped in the surrounding vertical filter cylinder, causing the particles to continuously accumulate towards the bottom sewage discharge channel. The accumulated dust particles exert a continuously increasing downward pressure on the movable contact plate 33 below. When this pressure exceeds the preset elastic damping force of the helical spring 38, the movable contact plate 33 will move smoothly downward along the limiting direction, exposing the accumulated dust particles to the external sewage discharge area. At this time, the exposed impurities can be easily cleaned with tools. Throughout the sewage discharge process, the elastic squeezing force of the helical spring keeps the dust particles tightly packed, with no obvious gaps between the particles, effectively blocking the leakage channels of the cleaning liquid and structurally eliminating the risk of leakage. Ultimately, this achieves efficient, timely, and leak-free automatic discharge of solid impurities.

[0035] For details regarding the specific structure of the spiral sewage discharge mechanism 3, please refer to [link / reference needed]. Figure 7 and Figure 8 The mechanism features a second docking plate 32 integrally formed at the top of the screw 31, which is securely connected to the bottom of the rotor of the dual-shaft motor 113, ensuring stable and efficient power transmission. The screw 31 is entirely housed inside the vertical filter cylinder 110 and the bottom sewage discharge channel 111, allowing for the directional pushing of filtered solid impurities. The movable contact plate 33 has a set of limiting and fixing ears 39 on each side, with a rod through-hole 34 in the center of each ear for the limiting movable rod 35 to pass through, achieving precise guidance. The top of the limiting movable rod 35 is fixedly installed at the bottom of the hollow vessel 11 via an integrated third docking plate 36, ensuring a stable and reliable overall installation. A bottom limit is integrally set at its bottom end. Plate 37 effectively prevents the limiting and fixing ear 39 from slipping off; a spiral spring 38, which is kept in a compressed state, is sleeved on the rod between the bottom limiting plate 37 and the limiting and fixing ear 39 on the limiting movable rod 35, providing continuous upward elastic damping and reset support for the moving contact plate 33; when the screw 31 rotates in a direction under the drive of the dual output shaft motor 113, it can push the surrounding medium and solid impurities to move continuously downward, realizing the automatic collection and pushing of impurities; when the equipment is working, the drain channel 16 is connected to the inlet of the liquid circulation pump through the pipeline, and the curved liquid inlet channel 27 is connected to the outlet of the circulation pump to form a closed liquid circulation system; the air inlet channel 17 is connected to the carbon dioxide emission equipment to ensure continuous and stable dust collection operation.

[0036] During use, during equipment installation, the drain channel 16 is connected to the inlet of a liquid circulation pump via a pipe, the curved inlet channel 27 is connected to the outlet of the same liquid circulation pump via a pipe, and the air inlet channel 17 is connected to a device that emits carbon dioxide gas. Carbon dioxide gas containing dust enters the gas dust removal chamber 15 through the air inlet channel 17. After being atomized by the liquid, the liquid containing dust particles falls into the vertical filter cartridge 110 under gravity. The purified gas then rises and is discharged through the exhaust channel 18. Simultaneously, the liquid containing particles is filtered by the vertical filter cartridge 110, and the liquid moves towards the edge of the bottom storage chamber 14 through the filter holes, while solid particles accumulate in the vertical filter cartridge 110. The filtered liquid then enters the curved inlet channel 27 through the liquid circulation pump. Simultaneously, cleaning liquid enters the liquid pre-reserved chamber 24 along the curved inlet channel 27, and finally, it is discharged as atomized particles through each atomizing nozzle 210. When the atomized liquid encounters moving dust particles, it adsorbs them and causes them to fall downwards, thus performing adsorption-type cleaning of dust particles in the gas. After the dual-output shaft motor 113 is started, its rotor drives the hollow turntable 21 to rotate. The multiple revolving atomizing nozzles 210 cause the atomized particles discharged through it to move downwards in a spiral motion, thereby expanding the adsorption space of the atomized liquid for dust. The screw 31, which rotates with the dual-output shaft motor 113, causes the dust particles around it to move downwards. The continuously accumulating dust particles will push the moving contact plate 33 downwards. When the pushing force is greater than the elasticity of the spiral spring 38, the moving contact plate 33 will move downwards, and the dust particles that are in contact with it will be exposed to the external environment. At this time, tools can be used to clean up the exposed dust particles. During the process of discharging dust particles, due to the elastic compression, there are no gaps between the particles to prevent liquid leakage, thereby achieving timely discharge of solid particles.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
