Description

Technical Field

[0001] The invention belongs to the technical field of air treatment, and in particular relates to a CO2 absorption device. Background Art

[0002] The background technology of carbon dioxide (CO2) absorption equipment generally involves the fields of environmental protection, gas purification and energy utilization. With the rapid development of industrialization and urbanization, the emission of greenhouse gases, especially CO2, has increased significantly, which has had a significant impact on global climate change. Therefore, all countries are actively seeking technologies and methods to reduce CO2 emissions. CO2 absorption equipment is a device for capturing and removing CO2 from gas. They can be used in scenarios such as industrial emission sources, air purification, and control of the breathing environment.

[0003] There are mainly the following types of CO2 absorption equipment in the prior art: physical adsorption, chemical absorption, membrane separation, etc. Physical adsorption uses porous materials (such as activated carbon or zeolite) to adsorb CO2; chemical absorption usually uses amine solutions to react with CO2 to generate carbonates or bicarbonates, and then releases CO2 by heating and other methods; membrane separation uses the difference in the dissolution and diffusion rates of different gases in membrane materials to achieve CO2 separation. Although these methods have achieved certain results in certain applications, there are still some problems and challenges, such as low absorption efficiency, high equipment complexity, and high cost.

[0004] In response to the above problems, the research and development focus in recent years has been on improving CO2 absorption efficiency, reducing equipment costs, and improving equipment durability and adaptability. For example, improving the surface properties of adsorbent materials to increase adsorption capacity and adsorption rate, developing efficient and low-cost chemical absorbents, and designing new membrane materials and membrane separation systems. The development of new technologies and equipment not only helps to reduce industrial CO2 emissions, but also provides effective solutions in air purification and respiratory environment control. In view of this, most of the current low-cost CO2 absorption equipment still uses absorbents for treatment. However, as the amount of absorbent increases, this type of structure will cause insufficient pressure and reduced air flow permeability. Conventionally, most of the adsorption treatments use a single absorbent. The increasing amount of fillers to ensure sufficient adsorption and the reduction in air flow permeability have become a difficult technical difficulty to solve.

[0028] Beneficial effects:

[0029] This solution uses a filter cartridge to filter and remove dust and impurities during the intake process, and then the suction fan is pressurized to slow down the flow rate when entering a larger space, and then evenly passes through several filter element components filled with granular absorbents, and at the same time cooperates with the secondary acceleration fan to provide a suction force to increase the speed twice. The speed of the suction fan is increased by the acceleration gear set, and the secondary acceleration fan rotates at a high speed to form a structure of pressurization and suction, which ensures that the gas circulation speed will not be reduced while ensuring the stable adsorption of CO2 and a good air flow rate without reduction;

[0030] At the same time, this scheme uses the granular adsorbent of the filter element assembly to perform one-time adsorption to adsorb a large amount of CO2. The filter element assembly can be taken out to replace the granular adsorbent inside. The airflow after one adsorption forms a higher flow rate at the siphon position under the convergence of the shell. The dispersed spraying of the liquid adsorbent is controlled by the electronically controlled nozzle to mix it with the air to form a suspended water mist, which enters the larger space of the mixing chamber. The flow rate drops sharply, so that the air and the mist adsorbent are fully contacted until it passes through the throttle ring and is transmitted to the reflux assembly by the secondary acceleration fan. The liquid adsorbent is collected and refluxed into the liquid storage bottle under the low-temperature condensation of the reflux assembly and the spiral flow of the airflow. This method can cooperate with the traditional particle adsorption, and can cooperate with the method of dispersed contact of the liquefied absorbent with the air, and cooperate with the flow rate change of the flow process to achieve full contact, further remove CO2 in the air, and can ensure the airflow permeability while having a very significant CO2 removal rate compared with the same type of traditional devices;

[0031] At the same time, the driver draws air in through the exhaust port with the booster blades, pressurizing the liquid storage bottle, so that the pressure in the liquid storage bottle is directly proportional to the suction fan and the secondary acceleration fan. The greater the airflow, the greater the liquid supply pressure, and the electronically controlled nozzle can provide more liquid absorbent for spraying under control.

[0032] In summary, this solution achieves air filtration and multi-stage CO2 purification, has a good air flow rate, and ensures a higher CO2 absorption rate.

[0052] The side wall of the connection cover 41 is provided with a plurality of air exhaust ports 44, and the inner wall of the connection cover 41 is rotatably provided with booster blades 43 controlled by the driver 11;

[0053] The liquid outlet pipe 45 is communicated with the bottom end of the hose 10 .

[0054] By setting a connecting cover 41, the connecting cover 41 is located below the driver 11 and is used to cooperate with the connecting ring 42 to support the liquid storage bottle 12. At the same time, the internal booster blades 43 can rotate at high speed under the drive of the driver 11, and guide the surrounding air through the exhaust port 44 for pressurization. The pressurized air enters the liquid storage bottle 12 through the connecting ring 42. At this time, a certain pressure is present in the liquid storage bottle 12, which can meet the transmission of liquid from bottom to top through the hose 10.

[0055] Specifically, Figure 7As shown: the filter element assembly 6 includes a top sleeve 62 fixedly connected to the inner wall of the shell 1, the inner wall of the top sleeve 62 is sealed with a sealing cylinder 63, the bottom end of the sealing cylinder 63 is fixedly connected with a mesh cylinder 67, the inner wall of the mesh cylinder 67 is axially penetrated by a core cylinder 66, the top of the core cylinder 66 is fixedly connected with a top sealing plate 64, the top sealing plate 64 is sealingly fixed to the bottom of the sealing cylinder 63, the bottom end of the mesh cylinder 67 is threadedly matched with a threaded sealing seat 65, the bottom end of the core cylinder 66 axially penetrates the surface of the threaded sealing seat 65, and the bottom end of the mesh cylinder 67 is slidably fitted with a bottom sleeve 61.

[0056] Specifically, Figure 6 As shown: the inner wall of the shell 1 is fixedly connected with a lower support ring 15 and an upper support ring 16, the bottom sleeve 61 penetrates and is fixed on the surface of the lower support ring 15, the top sleeve 62 penetrates and is fixed on the surface of the upper support ring 16, the top sleeve 62 penetrates and is fixed on the surface of the shell 1, and a plurality of through holes 17 are opened on the surface of the upper support ring 16.

[0057] By setting the filter element assembly 6, the top sleeve 62 can cooperate with the sealing tube 63 to perform the top sealing cooperation to ensure that the airflow will not leak. The airflow can enter the core tube 66 through the threaded sealing seat 65 and evenly pass through the side wall of the core tube 66. Then, the granular absorbent on the inner wall of the mesh tube 67 can remove CO2 until the airflow passes through the mesh tube 67 and enters between the upper support ring 16 and the lower support ring 15, and passes through the through hole 17 opened on the surface of the upper support ring 16 to reach the top of the shell 1, and then enters the siphon bucket 33.

[0058] Specifically, Figure 4 As shown: the flow rate regulator 3 includes a mixing chamber 31, the lower surface of the mixing chamber 31 is connected to a transmission chamber 32, the lower surface of the transmission chamber 32 is fixedly connected to a gear chamber 34, the top of the mixing chamber 31 is connected to a siphon hopper 33, and the side wall of the gear chamber 34 is fixed with a plurality of support ribs 35;

[0059] The support rib 35 is fixedly connected to the inner wall of the housing 1, and a throttling ring 36 is installed at the bottom of the mixing chamber 31;

[0060] The acceleration gear set 5 is disposed in the gear chamber 34 , the secondary acceleration fan 9 is rotatably disposed in the transmission chamber 32 , and the high-speed shaft 55 penetrates and rotates on the inner walls of the transmission chamber 32 and the gear chamber 34 .

[0061] The flow rate regulator 3 includes a mixing chamber 31. The large space of the mixing chamber 31 can reduce the speed of the flowing airflow, so that the air forms turbulence inside to react with the liquid absorbent.

[0062] Specifically, Figure 3As shown: the reflux assembly 7 includes a bracket 71 fixedly connected to one side of the housing 1, a condensation tank 72 is fixedly connected to the surface of the bracket 71, a spiral plate 73 is fixed to the inner wall of the condensation tank 72, and a refrigerator 74 for cooling the inner wall of the condensation tank 72 is installed on one side of the condensation tank 72;

A solenoid valve 76 is installed at the bottom end of the U-shaped tube 75, and the solenoid valve 76 is connected to a reflux pipe 77. The bottom end of the reflux pipe 77 is connected to the reflux interface 46, and a one-way valve 78 is arranged on the surface of the reflux pipe 77.

[0064] Specifically, Figure 3 As shown: one side of the airtight chamber is connected to an air inlet 13, and the inner wall of the airtight chamber is provided with a filter cartridge 14 for air filtering.

[0065] The air inlet 13 can guide the airflow into the airtight chamber, and cooperate with the filter cartridge 14 in the airtight chamber to filter the airflow to prevent impurities and dust from entering the space.

[0066] Specifically, Figure 5 As shown: the acceleration gear set 5 includes a plurality of shaft frames 56 fixedly connected to the inner wall of the gear chamber 34, and a driven gear 52 and a transmission gear 53 are rotatably arranged on the surface of the shaft frame 56, and the driven gear 52 and the transmission gear 53 are coaxially rotatably arranged, and the plurality of driven gears 52 are jointly meshed with a driving gear 51, and the plurality of transmission gears 53 are jointly meshed with an output gear 54, and the output gear 54 is fixedly connected to a high-speed shaft 55, and the high-speed shaft 55 is fixedly connected to the secondary acceleration fan 9.

[0067] By setting up the acceleration gear set 5, the shaft frame 56 can support the driven gear 52 and the transmission gear 53, the driving gear 51 can drive the driven gear 52 to rotate quickly, and at the same time, the driven gear 52 coaxially drives the transmission gear 53 to rotate, and the transmission gear 53 further drives the output gear 54 to rotate at a high speed, thereby realizing a two-stage speed increase output.

[0068] Specifically, Figure 6 and Figure 7 As shown, a handle is provided at the top of the sealing cylinder 63, and a series frame 18 is commonly installed at the tops of a plurality of sealing cylinders 63.

[0069] The handle at the top of the sealing cylinder 63 can be easily taken out, and the serial rack 18 can easily take out multiple sealing cylinders 63 at the same time to replace the granular absorbent.

[0070] Specifically, Figure 2 and Figure 3As shown: the upper surface of the inner wall of the shell 1 is arranged in an annular inverted arc shape, and the electric control nozzle 19 is sealed and penetrates the axis of the annular inverted arc.

[0071] The inner wall of the shell 1 is arranged in an annular inverted arc shape, which can guide the airflow so that the airflow can be gathered into the siphon bucket 33 under the guidance, thereby realizing high-speed airflow.

[0072] In this solution, dust and impurities are first filtered and removed by the filter cartridge 14 during the intake process, and the air enters a larger space and slows down its flow rate after being pressurized by the suction fan 8, and then evenly passes through a number of filter element components 6 filled with granular absorbents, and at the same time cooperates with the secondary acceleration fan 9 to provide a suction force to increase the speed twice. The speed of the suction fan 8 is increased by the acceleration gear set 5, and the secondary acceleration fan 9 rotates at a high speed, so that a structure of one pressurization and one suction is formed;

[0073] At the same time, the present invention performs a one-time adsorption through the granular adsorbent of the filter element assembly 6 to adsorb a large amount of CO2. The filter element assembly 6 can be taken out to replace the granular adsorbent inside. The airflow after one adsorption forms a higher flow rate at the position of the siphon 33 under the convergence effect of the shell 1. The dispersed spraying of the liquid adsorbent is controlled by the electronically controlled nozzle 19 to mix with the air to form a suspended water mist, which enters the larger space of the mixing chamber 31, and the flow rate drops suddenly, so that the air and the mist adsorbent are fully in contact, until it passes through the throttling ring 36 and is transmitted to the reflux assembly 7 by the secondary acceleration fan 9, and the liquid adsorbent is collected and refluxed into the liquid storage bottle 12 under the low-temperature condensation of the reflux assembly 7 and the spiral flow of the airflow;

[0074] At the same time, the driver 11 draws air with the boost blades 43 through the exhaust port 44 to pressurize the liquid storage bottle 12, so that the pressure of the liquid storage bottle 12 is directly proportional to the suction fan 8 and the secondary acceleration fan 9. The greater the airflow, the greater the liquid supply pressure, and the electronically controlled nozzle 19 can provide more liquid absorbent for spraying under control.

[0075] In summary, this solution adopts a multi-stage purification structure. First, the filter cartridge 14 removes dust and impurities in the intake air to ensure that the gas entering the device is pure. Subsequently, the suction fan 8 pressurizes the gas and enters the filter element assembly 6 filled with granular absorbent for adsorption. The secondary acceleration fan 9 provides further airflow acceleration to ensure that the gas circulation speed does not decrease, thereby ensuring efficient and stable adsorption of CO2.

[0076] The device combines the dual adsorption mechanism of granular adsorbent and liquid adsorbent. After the granular adsorbent performs preliminary adsorption, the liquid adsorbent is dispersed in the mixing chamber 31 in the form of suspended water mist, fully contacting the airflow, and further improving the CO2 removal efficiency through low-temperature condensation and spiral flow of the airflow. This dual adsorption design significantly improves the purification capacity of the device.

[0077] The filter element assembly 6 is designed to be a detachable and replaceable structure, so that the user can easily replace the internal granular adsorbent, thereby extending the service life of the equipment and reducing maintenance costs.

[0078] The combined use of the suction fan 8 and the secondary acceleration fan 9, and the driver 11 driving the booster blades 43 to pressurize the liquid storage bottle 12, realizes the dynamic adjustment of the air flow and the liquid supply pressure. This not only ensures the air flow of the equipment, but also enhances the dispersion effect of the liquid adsorbent, ensuring the full adsorption of CO2.

[0079] This solution innovatively combines traditional particle adsorption with the dispersion of liquid absorbents, and uses the speed change of airflow and the design of flow paths to achieve efficient removal of CO2. This dual adsorption mechanism greatly improves the purification efficiency while ensuring smooth airflow.
