Description

Technical Field

[0001] The present invention relates to the technical field of gas adsorption separation, and particularly relates to an air carbon capture adsorption device. Background Art

[0002] Carbon dioxide (CO2) is a major greenhouse gas. Due to the combustion of fossil fuels, the concentration of CO2 in the atmosphere has increased sharply in the past century, and global warming is having a devastating impact on our climate, health, and communities. In recent years, people have begun to study direct air capture (DAC) technology for capturing carbon dioxide from ambient air.

[0003] DAC generally uses a solid adsorbent bed to directly capture CO2 in the air. The solid adsorbent can adsorb CO2 in the air at normal temperature and pressure, and can be regenerated and release the captured CO2 using the lower temperature (80 - 100 °C) provided by industrial waste heat or solar heat, etc.

[0004] In the prior art, such as the invention patent with the patent number CN117358012A, a fluidized bed adsorption method direct air capture system and method are disclosed. The fluidized bed is used for adsorption and desorption, and continuous operation of the adsorption and desorption processes can be achieved; the fluidized bed has an extremely low pressure drop, which can significantly reduce the fan power consumption in the direct air capture scenario with a high gas treatment volume.

[0005] Although the fluidized bed used in the above prior art is more effective, since the desorption tower is circularly connected to the adsorption tower through a pneumatic conveying system, gas interaction will occur between the adsorption tower and the desorption tower through the conveying pipeline in the pneumatic conveying system. It is easy for the miscellaneous gas in the adsorption tower to enter the desorption tower, and the product gas flow in the desorption tower is likely to leak into the adsorption tower, affecting the airtightness of the desorption tower. On the one hand, it will dilute the product gas in the desorption tower and affect the product quality of the captured CO2.

[0006] On the other hand, due to capacity reduction and stability problems, direct steam heating has been largely avoided for other well-developed commercial adsorbents (such as zeolites). Currently, it is more inclined to use inert gas or finished CO2 as the heating medium. However, due to the airtightness problem of the desorption tower, the loss of the gas heating medium is large, and it is difficult to implement in actual production.

[0007] Based on this, it is necessary to study an air carbon capture adsorption tower system. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide an air carbon capture adsorption tower system and process, which can effectively solve the problem of gas interaction between the adsorption tower and the desorption tower in the existing fluidized bed technology, and further lead to the problems of serious dilution of the product gas and large loss of the gas heating medium.

[0009] To achieve the above object, the technical solution adopted by the present invention is as follows: An air carbon capture adsorption device includes an adsorption pipeline, a desorption pipeline, a feeding pipeline, a return pipeline, a conveying mechanism, an adsorption disc and an air blocking device; The adsorption pipeline, the feeding pipeline, the desorption pipeline and the return pipeline are horizontally arranged and connected end to end in sequence to form a horizontal circulation pipeline; The conveying mechanism is circularly arranged in the circulation pipeline, and a plurality of adsorption discs are vertically arranged at intervals in the conveying direction on the conveying mechanism; Both ends of the adsorption pipeline are respectively provided with an air inlet and an air outlet; One end of the desorption pipeline is provided with an inlet pipe, and the inlet pipe continuously conveys heated inert gas to the desorption pipeline; the other end of the desorption pipeline is provided with an outlet pipe, and the outlet pipe is communicated with a product gas collection system; Air blocking devices are arranged in both the feeding pipeline and the return pipeline. The air blocking device includes a plurality of jet heads arranged at intervals. The jet heads continuously output inert gas, so that air barriers that hinder the flow of gas along the length direction are formed in both the feeding pipeline and the return pipeline.

[0010] Further, the product gas collection system includes a condensation separator, and the input port of the condensation separator is connected to the outlet pipe; The gas supply end of the inlet pipe is connected to the output port of the heating tank; The inert gas output port of the condensation separator is communicated with the heating tank, so that the inert gas passes through the inlet pipe, the desorption pipeline, the outlet pipe and the condensation separator in sequence from the heating tank, and finally returns to the heating tank to form a gas desorption cycle.

[0011] Further, the jet head includes a first jet head and a second jet head. The first jet head is arranged obliquely downward from top to bottom towards the desorption pipeline; the second jet head is arranged obliquely downward from top to bottom towards the adsorption pipeline, forming two mutually separated inclined air barriers.

[0012] Further, the gas supply end of the first jet head in the feeding pipeline is connected to the inert gas output port of the condensation separator, and the gas supply end of the first jet head in the return pipeline is connected to the output end of the heating tank, forming an internal air barrier cycle.

[0013] Further, a return air pipe is communicated in both the feeding pipeline and the return pipeline. The return air pipe is located between the air barrier and the adsorption pipeline; both groups of return air pipes are communicated to a gas separator, the inert gas output port of the gas separator is connected to the gas supply end of the second jet head, and the miscellaneous gas output port of the gas separator is communicated to the outside, forming an external air barrier cycle.

[0014] Furthermore, the middle parts of the material feeding pipeline and the material returning pipeline are both provided with transition and narrowing structures. The middle area at the bottom of the transition and narrowing structure forms a narrowing upward, making the middle of the transition and narrowing structure narrow but expanding on both sides; The top of the adsorption disc is suspended and connected to the conveying mechanism through a sling. When the adsorption disc enters the transition and narrowing structure, it gradually tends to be in a horizontal state and gradually returns to a vertical state when leaving.

[0015] Furthermore, the air barrier is arranged in the middle of the transition and narrowing structure and on the side close to the desorption pipeline.

[0016] Furthermore, the adsorption disc includes a fixed frame, a filter screen, and a solid adsorbent; The top of the fixed frame is suspended and connected to the conveying mechanism through a sling, and a counterweight is arranged at the bottom of the fixed frame; The fixed frame is penetrated from front to back. Two layers of filter screens are arranged at intervals in the front and back of the fixed frame. A number of quilts are arranged between the two layers of filter screens, so that a plurality of storage areas are formed between the two layers of filter screens, and the solid adsorbent is stored in the storage areas.

[0017] Furthermore, runners are arranged at the front and rear ends of the counterweight.

[0018] Furthermore, a cooler is arranged on the material returning pipeline, and the cooler is located between the air barrier and the adsorption pipeline.

[0019] The beneficial effects of the above technical solutions are as follows: (1) In the present invention, the adsorption pipeline, the material feeding pipeline, the desorption pipeline, and the material returning pipeline are horizontally arranged and connected end to end in sequence to form a horizontal circulating pipeline. A conveying mechanism circulates in the circulating pipeline. A plurality of adsorption discs are vertically arranged at intervals in the conveying direction on the conveying mechanism. The plurality of adsorption discs adsorb carbon dioxide in the adsorption pipeline and are desorbed and restored in the desorption pipeline to form a fluidized bed system; Air blocking devices are arranged in both the material feeding pipeline and the material returning pipeline. A plurality of jet nozzles continuously output inert gas to form an air barrier in the pipeline, blocking the flow of gas along the adsorption pipeline or the desorption pipeline, effectively avoiding gas interaction between the adsorption pipeline and the desorption pipeline, preventing the high-concentration product gas (carbon dioxide) in the desorption pipeline from leaking into the adsorption pipeline through the adsorption pipeline or the material feeding pipeline, and also avoiding the miscellaneous gas in the adsorption pipeline from entering the desorption pipeline through the adsorption pipeline or the material feeding pipeline, effectively solving the problem of gas interaction between the adsorption tower and the desorption tower in the existing fluidized bed technology, and further solving the problems of product gas dilution and serious loss of gas heating medium, ensuring the purity and quality of the product gas, reducing the loss of the inert gas as the gas heating medium, and having good economic benefits.

[0020] (2) In the middle of the feeding pipeline and the material return pipeline of the present invention, a transition and constriction structure is provided. In the middle area at the bottom of the transition and constriction structure, a constriction is formed upwards, making the middle of the transition and constriction structure narrow but expanding on both sides. On the one hand, the constriction section forms a horizontal constriction in the middle of the feeding pipeline and the material return pipeline, which can reduce the cross-sectional area. The air barrier is arranged in the middle of the transition and constriction structure and close to the side of the desorption pipeline, which can concentrate the air flow path, effectively enhance the sealing performance of the air barrier, and reduce gas leakage and inert gas consumption. On the other hand, the top of the adsorption disc is suspended and connected to the conveying mechanism through a sling. The bottom of the adsorption disc will gradually tend to be horizontal under the guidance of the inclined plate and gradually return to the vertical state when leaving, ensuring that the adsorption disc can smoothly pass through the transition and constriction structure.

[0021] (3) The inert gas output by the first jet head enters the desorption pipeline through the material return pipeline, and returns to the corresponding first jet head through the gas outlet pipe, the condensation separator and the heating tank, forming an internal air barrier cycle, which can effectively prevent the product gas in the desorption pipeline from flowing from the feeding pipeline or the material return pipeline to the adsorption pipeline; the inert gas output by the second jet head passes through the feeding pipeline or the material return pipeline, enters the gas separator from the gas return pipe, and finally returns to the second nozzle, forming an external air barrier cycle, which can effectively prevent the miscellaneous gas in the adsorption pipeline from flowing from the gas supply pipeline or the gas return pipeline to the desorption pipeline. The design of the inner and outer two-layer air barriers can effectively improve the isolation effect of the air blocking device. Description of the Drawings

Detailed implementation manners

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners: This embodiment aims to provide an air carbon capture adsorption device, which is mainly used for directly capturing CO2 in the air by DAC technology. Aiming at the problem of gas interaction between the adsorption tower and the desorption tower in the existing fluidized bed technology, which leads to serious problems such as product gas dilution and gas heating medium loss.

[0025] An air carbon capture adsorption device, such as Figure 1 and Figure 2 comprises an adsorption pipeline 1, a desorption pipeline 2, a feeding pipeline 3, a return pipeline 4, a conveying mechanism 5, an adsorption tray 6 and an air blocking device; the adsorption pipeline 1, the feeding pipeline 3, the desorption pipeline 2 and the return pipeline 4 are horizontally arranged and connected end to end in sequence to form a horizontal circulation pipeline. Specifically, as Figure 2 , the output end of the adsorption pipeline 1 is communicated with the input end of the feeding pipeline 3, the output end of the feeding pipeline 3 is communicated with the input end of the desorption pipeline 2, the output end of the desorption pipeline 2 is communicated with the input end of the return pipeline 4, and the output end of the return pipeline 4 is communicated with the input end of the adsorption pipeline 1.

[0026] As Figure 2 , the conveying mechanism 5 is circularly arranged on the top plate inside the circulation pipeline. A plurality of adsorption trays 6 are vertically arranged at intervals along the conveying direction on the conveying mechanism 5. An adsorbent is arranged on the adsorption trays 6 for adsorbing carbon dioxide in the air. The conveying mechanism 5 is mainly used for circulating the adsorption trays 6 in the circulation pipeline. In this example, the conveying mechanism 5 circulates in the clockwise direction and can adopt a chain conveyor mechanism, a track-type conveying mechanism 5, etc. Its specific structure and working principle both adopt the existing technology and will not be elaborated here.

[0027] Both ends of the adsorption pipeline 1 are respectively provided with an air inlet 101 and an air outlet 102. Fans are correspondingly arranged on the air inlet 101 and the air outlet 102, which are mainly used for extracting air from the outside into the adsorption pipeline 1 and forming an air path in the adsorption pipeline 1, so that the adsorption trays 6 in the adsorption pipeline 1 capture carbon dioxide in the passing air, and finally the air is discharged from the air outlet 102 to the outside to form an air capture cycle.

[0028] As Figure 1 and Figure 2 , one end of the desorption pipeline 2 is provided with an inlet pipe 201, and an air pump is arranged on the inlet pipe 201. The inlet pipe 201 continuously conveys heated inert gas into the desorption pipeline 2 for heating the adsorption trays 6 in the desorption pipeline 2 to make them desorb and restore, and release the captured carbon dioxide. The inert gas adopts nitrogen.

[0029] The other end of the desorption pipeline 2 is provided with an outlet gas pipe 202, and the outlet gas pipe 202 is connected to the product gas collection system for collecting the desorbed carbon dioxide. The product gas collection system includes a condensation separator 9. The input port of the condensation separator 9 is connected to the outlet gas pipe 202. The condensation separator 9 is mainly used for separating carbon dioxide, inert gas and water, and cooling and drying the collected gas. Its specific structure and working principle both adopt the existing technology and will not be elaborated here.

[0030] The gas supply end of the inlet pipe 201 is connected to the output port of the heating tank 10. The heating tank 10 is used for storing and heating the inert gas. The inert gas output port of the condensation separator 9 is communicated with the heating tank 10. The inert gas passes through the inlet pipe 201, the desorption pipeline 2, the outlet gas pipe 202 and the condensation separator 9 in sequence from the heating tank 10, and finally returns to the heating tank 10 to form a gas desorption cycle.

[0031] Air blocking devices are arranged in both the feeding pipeline 3 and the return pipeline 4. The air blocking device includes a plurality of jet heads 7 arranged at intervals. The jet heads 7 continuously output inert gas, so that air barriers that hinder the gas from flowing along the length direction are formed in both the feeding pipeline 3 and the return pipeline 4, thereby realizing gas isolation between the adsorption pipeline 1 and the desorption pipeline 2 without affecting the normal cyclic transportation of the solid adsorbent 603.

[0032] A cooler 13 is arranged on the return pipeline 4. The cooler 13 is located between the air barrier and the adsorption pipeline 1 and is used for cooling the adsorption tray 6 about to enter the adsorption pipeline 1 to ensure that the solid adsorbent 603 in the adsorption tray 6 is regenerated and has the adsorption capacity.

[0033] The jet head 7 includes a first jet head 701 and a second jet head 702. As Figure 4 , the first jet head 701 faces the desorption pipeline 2 and is arranged obliquely from top to bottom, forming an air barrier inclined towards the desorption pipeline 2, and making the ejected gas flow along the feeding pipeline 3 or the return pipeline 4 to the desorption pipeline 2, forming an air flow towards the desorption pipeline 2, which can effectively block the product gas in the desorption pipeline 2 from flowing from the feeding pipeline 3 or the return pipeline 4 to the adsorption pipeline 1. The gas supply end of the first jet head 701 located in the feeding pipeline 3 is connected to the inert gas output port of the condensation separator 9, and the gas supply end of the first jet head 701 located in the return pipeline 4 is connected to the output end of the heating tank 10, so that the inert gas output from the first jet head 701 in the feeding pipeline 3 enters the desorption pipeline 2 through the feeding pipeline 3, and returns to the corresponding first jet head 701 through the outlet gas pipe 202 and the condensation separator 9; so that the inert gas output from the first jet head 701 in the return pipeline 4 enters the desorption pipeline 2 through the return pipeline 4, and returns to the corresponding first jet head 701 through the outlet gas pipe 202, the condensation separator 9 and the heating tank 10, forming an internal air barrier cycle.

[0034] The second jet head 702 is arranged obliquely downward from top to bottom towards the adsorption pipeline 1, forming two inclined air barriers that are far away from each other with the first jet head 701. The gas ejected from the second jet head 702 flows along the air supply pipeline or the air return pipeline 11 into the adsorption pipeline 1, which can effectively prevent the miscellaneous gas in the adsorption pipeline 1 from flowing from the air supply pipeline or the air return pipeline 11 to the desorption pipeline 2.

[0035] An air return pipeline 11 is connected in the air supply pipeline 3 and the material return pipeline 4. An air pump is arranged on the air return pipeline 11, and the air return pipeline 11 is located between the outer air barrier and the adsorption pipeline 1; both groups of air return pipelines 11 are connected to the gas separator 12. The gas separator 12 can separate the inert gas from the inert gas and the air. A membrane separation device can be used, aiming to preliminarily separate nitrogen to reduce losses, and the requirement for separation accuracy is relatively low. Its specific structure and working principle both adopt the existing technology and will not be elaborated here. The inert gas output port of the gas separator 12 is connected to the air supply end of the second jet head 702, and the miscellaneous gas output port of the gas separator 12 is communicated to the outside, so that the inert gas output from the second jet head 702 enters the gas separator 12 through the air supply pipeline 3 or the material return pipeline 4 and from the air return pipeline 11, and finally returns to the second nozzle to form an outer air barrier cycle. Since the inert gas in it will be gradually diluted, it needs to be replaced regularly. Low-grade inert gas can be used to reduce costs.

[0036] Considering that it is relatively difficult to adopt an air barrier when the cross-sectional areas of the air supply pipeline 3 and the material return pipeline 4 are relatively large. For this reason, as Figure 3 , the middle parts of the air supply pipeline 3 and the material return pipeline 4 are both set as transition and constriction structures. The middle area at the bottom of the transition and constriction structure forms a constriction upward, making the transition and constriction structure present the characteristics of being narrow in the middle but expanding on both sides. Specifically, the bottom of the transition and constriction structure includes a middle constriction section 301 and inclined sections 302 connected to both sides of the constriction section 301. The inclined sections 302 are connected to other parts of the corresponding air supply pipeline 3 or material return pipeline 4. The constriction section 301 makes the middle parts of the air supply pipeline 3 and the material return pipeline 4 form a horizontal constriction, which can reduce the cross-sectional area. The air barrier is arranged in the middle of the transition and constriction structure and on the side close to the desorption pipeline 2, so as to facilitate the implementation of the air barrier.

[0037] A lifting ring is arranged on the top of the adsorption disc 6, and the lifting ring is suspended and connected to the conveying mechanism 5 through a sling 8, as Figure 3 , when the adsorption disc 6 enters the transition and constriction structure, the bottom of the adsorption disc 6 will gradually tend to be horizontal under the guidance of the inclined plate and gradually return to the vertical state when leaving, so that the adsorption disc 6 can pass through the transition and constriction structure.

[0038] As Figure 5 and Figure 6, the suction disc 6 includes a fixed frame 601, a filter screen 602 and a solid adsorbent 603; a hook is provided at the top of the fixed frame 601, and the hook is suspended and connected to the conveying mechanism 5 through a sling 8. A counterweight 605 is provided at the bottom of the fixed frame 601. The counterweight 605 is used to ensure that the suction disc 6 is in a vertical state in the area outside the transition necking structure, and can effectively resist the disturbance of the air path. Rotating wheels 606 are provided at the front and rear ends of the counterweight 605, which can reduce the friction between the suction disc 6 and the inclined section 302. The fixed frame 601 is penetrated front and rear. Two layers of filter screens 602 are arranged at intervals in the front and rear of the fixed frame 601. A number of quilts 604 are arranged between the two layers of filter screens 602, so that a plurality of storage areas are formed between the two layers of filter screens 602, and the solid adsorbent 603 is stored in the storage areas. The filter screen 602 can intercept the solid adsorbent 603 but allows air to pass through. The design of the quilts 604 and the storage areas enables the solid adsorbent 603 to be evenly and vertically arranged in the suction disc 6, avoiding accumulation, increasing the contact area between the solid adsorbent 603 and the air, and enabling effective reaction with the air.
