Description

TECHNICAL FIELD

[0001] The utility model relates to air carbon capture technical field especially relates to a carbon dioxide recycling regeneration trapping device. BACKGROUND

[0002] Direct air capture CO2 technology is a technology that can capture CO2 directly from the surrounding air and concentrate it for storage or reuse, which is particularly important for reducing CO2 emissions from dispersed sources such as transportation, agriculture, forestry, and construction, and helps to achieve the goal of near-zero emissions.

[0003] However, the traditional alkaline adsorption material has low efficiency when absorbing CO2 in the air, not only needs more energy to regenerate these materials for reuse, but also has limited selectivity and absorption capacity for CO2, which means they are not suitable for the demand of direct air capture CO2, and the current direct air capture device also has the problems of high energy consumption and wide land occupation, and needs to be regenerated at a very high temperature, which further increases energy consumption. SUMMARY

[0004] The utility model discloses a carbon dioxide recycling regeneration trapping device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A carbon dioxide recycling regeneration trapping device, comprising a support, the support is sequentially fixed from top to bottom with a cooling bin, an adsorption bin and a regeneration bin, further comprising a feeding cylinder fixed on the other side of the support, a spiral auger is rotatably installed in the feeding cylinder, a motor connected with the spiral auger is fixedly installed at the top of the feeding cylinder, the cooling bin, the adsorption bin and the regeneration bin are fixedly connected and communicated through a discharge pipe, the adsorption bin and the cooling bin are connected and communicated through a plurality of air pipes arranged around the discharge pipe, the top end of the air pipe is provided with a breathable film, the bottom end of the regeneration bin and the bottom side of the feeding cylinder are fixedly connected and communicated through a downward inclined discharge pipe, and the top end of the cooling bin and the top side of the feeding cylinder are fixedly connected and communicated through an upward inclined feeding pipe.

[0007] As a further description of the above technical scheme:

[0008] The cooling bin is provided with a cooling water cavity between the inner and outer walls, the regeneration bin is provided with a steam water cavity between the inner and outer walls, the cooling water cavity and the steam water cavity are fixedly connected and communicated through a connecting pipe, a steam generator is installed on the connecting pipe, a cold water inlet pipe is fixedly connected to the bottom side of the cooling water cavity, and a steam outlet pipe is fixedly connected to the bottom side of the steam water cavity.

[0009] As a further description of the above technical scheme:

[0010] The bottom side of the adsorption bin is fixedly communicated with an air inlet pipe, and a blower, a filter and a control valve are sequentially arranged on the air inlet pipe in the gas flow direction.

[0011] As a further description of the above technical solution:

[0012] The top of the cooling bin is fixedly communicated with an exhaust pipe, and a carbon dioxide detector is arranged on the exhaust pipe.

[0013] As a further description of the above technical solution:

[0014] The top of the regeneration bin is fixedly communicated with a gas collecting bin through the air pipe.

[0015] As a further description of the above technical solution:

[0016] An electric control unloading valve is arranged on each group of unloading pipes.

[0017] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0018] 1. In the present application, the blower sends air into the adsorption bin through the air inlet pipe and after filtration by the filter (to remove particulate impurities in the air), the air contacts the carbon dioxide adsorbent filled in the adsorption bin, and the carbon dioxide in the air is adsorbed. When the carbon dioxide adsorbent is saturated, the control valve is closed, the purified air enters the cooling bin through the air pipe, and contacts the regenerated carbon dioxide adsorbent filled in the cooling bin, thereby improving the carbon dioxide capture efficiency of the device. The twice-purified air is discharged through the exhaust pipe, and the carbon dioxide content in the purified air is monitored by the carbon dioxide detector. Not only is the carbon dioxide in the air removed, but the overall carbon dioxide capture efficiency is also improved by utilizing the characteristics of the regenerated adsorbent, thereby ensuring a higher carbon dioxide removal rate.

[0019] 2. In the present application, cold water enters the cooling water cavity through the cold water inlet pipe, and flows out of the cooling water cavity through the connecting pipe, thereby cooling the high-temperature desorbed regenerated carbon dioxide adsorbent stored in the cooling bin. After the cooling process is completed, the cold water becomes warm water, the warm water in the connecting pipe becomes steam in the steam generator, and the steam enters the steam water cavity and is discharged through the steam outlet pipe. The steam temperature is 95-115 DEG C. The high-temperature steam desorbs the carbon dioxide adsorbent (adsorbed saturation), and pure carbon dioxide is desorbed. The adsorbent is reduced (i.e., regenerated carbon dioxide adsorbent). This process not only effectively desorbs pure carbon dioxide, but also reduces the adsorbent, i.e., regenerates the adsorbent that can be used for adsorbing carbon dioxide again. This recycling mechanism not only improves the use efficiency of the adsorbent, but also significantly reduces the cost and environmental impact of carbon dioxide capture.

[0028] Specifically, as Figs. 1-3As shown, the cooling bin 8, the adsorption bin 2 and the regeneration bin 15 are fixedly communicated through the discharge pipe 19, each group of the discharge pipe 19 is provided with an electric control discharge valve 17, the feeding cylinder 12 is rotatably provided with a spiral auger 18, the feeding cylinder 12 is fixedly provided with a motor 13 which is drivingly connected with the spiral auger 18, the bottom end of the regeneration bin 15 is fixedly communicated with the bottom side of the feeding cylinder 12 through a downwardly inclined discharge pipe 16, and the top end of the cooling bin 8 is fixedly communicated with the top side of the feeding cylinder 12 through an upwardly inclined feeding pipe 11.
