Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon capture device technology, and in particular to a carbon capture multilayer cyclone separation device. Background Technology
[0002] Flue gas is treated by electrostatic precipitators or bag filters to remove particulate matter and prevent adsorbent pore blockage. Wet or dry desulfurization is used to avoid SO2 and CO2 competing for adsorption sites. Selective catalytic reduction technology is used to reduce the poisoning effect of nitrogen oxides on the adsorbent. Flue gas temperature and humidity are controlled to optimize the working conditions of the adsorbent.
[0003] The treated flue gas is captured using amine-modified activated carbon. Under normal or slightly positive pressure, the treated flue gas is adsorbed by the amine-modified activated carbon. Carbon capture directly reduces greenhouse gas emissions, contributing to carbon neutrality. However, the particle-accumulated amine-modified activated carbon obstructs gas flow, reducing the efficiency of activated carbon capture. Therefore, those skilled in the art have provided a multi-layer cyclone separator for carbon capture to address the problems mentioned in the background section. Utility Model Content

[0020] 2. Beneficial effects
[0021] Compared with existing technologies, the advantages of this utility model are:
[0022] This invention guides the treated flue gas into the interior of a mesh cylinder. The mesh cylinder contains amine-modified activated carbon in its interlayer. As the treated flue gas passes through the mesh cylinder, it comes into contact with the amine-modified activated carbon. Carbon dioxide in the flue gas also contacts the amine-modified activated carbon, while the flue gas flows out through the gaps between the amine-modified activated carbon particles. Upon entering the mesh cylinder, a rotating plate causes the flue gas to rotate, dividing the interior of the mesh cylinder into multiple spaces connected by holes. When the flue gas throughput is low, the compressed flue gas automatically rises and enters different positions within the mesh cylinder, contacting the amine-modified activated carbon inside. The rotating plate slaps the treated flue gas into the mesh cylinder, aiding in its flow. The flue gas vortexes as it contacts the mesh cylinder and flows upwards, further improving the flow and efficiency of the treated flue gas through the mesh cylinder, thus enhancing carbon capture efficiency.

[0038] Example 1
[0039] Please see Figures 1-5 As shown, this embodiment is a carbon capture multilayer cyclone separator, including a separation cylinder 100.
[0040] The carbon capture structure 300 includes a mesh cylinder 302 fixed inside the lower end of the separation cylinder 100 and open at the upper end, granular amine-modified activated carbon filled inside the mesh cylinder 302, partitions 306 evenly distributed on the inner wall of the mesh cylinder 302, holes 308 staggeredly distributed inside the partitions 306, a rotating shaft 305 rotatably installed inside the partitions 306, and rotating plates 307 arranged in a ring array between the partitions 306 and connected to the rotating shaft 305.
[0041] as well as;
[0042] The maintenance structure 200 includes a closed cover 201 located at the upper end of the mesh cylinder 302, a nut 212 located at one end of the closed cover 201, a slider 209 located at one end of the nut 212 and the closed cover 201, a guide rail 207 located on the inner wall of the mesh cylinder 302 and slidably mounted with the slider 209, a motor 205 located at the upper end of the separation cylinder 100, a bearing 206 embedded and mounted inside the upper end of the separation cylinder 100, and a screw 208 located at the lower end of the motor 205, rotatably mounted inside the bearing 206, and threadedly connected to the nut 212; a flow guide 202 is provided at the upper end of the separation cylinder 100, a conveying pipe 204 is provided at the upper end of the flow guide 202, and a gas detector 203 is provided inside the conveying pipe 204;
[0043] The separator 100 has an inspection port 210 at one end, and an inspection door 211 that covers the inspection port 210 and is fixed by bolts is provided on the outer wall of the separator 100. A support frame 101 is provided on the outer wall of the separator 100.
[0044] The lower end of the closed cover 201 is provided with a ring plug 213 in the upper opening of the mesh cylinder 302. The upper end of the closed cover 201 is provided with a motor 304 whose output end is rotatably mounted on the closed cover 201. The lower end of the motor 304 is provided with a rotating ring 313. The lower end of the rotating ring 313 is provided with rotating rods 314 arranged in a ring array. The upper end of the rotating shaft 305 is provided with a support ring 311. The upper end of the support ring 311 is provided with side rods 312 arranged in a ring array and located between the rotating rods 314.
[0045] A travel channel 303 is provided between the separation cylinder 100 and the mesh cylinder 302. The upper end of the separation cylinder 100 is connected to the travel channel 303. The lower end of the separation cylinder 100 is provided with a discharge pipe 301 that is connected to the lower end of the mesh cylinder 302 and is controlled by a valve.
[0046] The lower end of the separator 100 is provided with a diffuser 309 whose radius decreases from top to bottom, and the lower end of the diffuser 309 is connected to an input pipe 310;
[0047] The maintenance structure 200 and the carbon capture structure 300 are used;
[0048] When the device is powered on, the treated flue gas enters the diffuser hood 309 through the input pipe 310. After being evenly distributed by the diffuser hood 309, it enters the bottom of the mesh cylinder 302. The motor 304 drives the rotating ring 313 to rotate, which in turn drives the rotating rod 314 to periodically move the side rod 312, so that the rotating shaft 305 and the rotating plate 307 rotate synchronously. The flue gas forms a vortex airflow under the push of the rotating plate 307, spirals up along the inner wall of the mesh cylinder 302, and passes through the holes 308 of the partition 306 in sequence to enter the multi-layer space. The amine-modified activated carbon particles come into full contact with the flue gas and adsorb carbon dioxide.
[0049] The purified gas enters the guide hood 202 through the stroke channel 303 and is discharged through the delivery pipe 204. The gas detector 203 monitors the carbon dioxide concentration in real time. If the concentration exceeds the standard, the amine-modified activated carbon particles need to be replaced. When the adsorption is saturated, the valve is closed, the motor 205 is started to drive the screw 208 to rotate, and the nut 212 cooperates with the slider 209 to lift the closed cover 201, exposing the opening of the mesh cylinder 302. The closed cover 201 is then reset and the device is restarted.
[0050] By optimizing gas-solid contact efficiency through multi-layer swirling design, in traditional fixed beds, flue gas tends to flow along the path of least resistance, resulting in uneven utilization of activated carbon. This device uses a rotating plate 307 to force flue gas to form a vortex, extending the gas residence time. At the same time, the baffle plate 306 and the holes 308 divide the mesh cylinder 302 into multiple spaces, and the centrifugal force generated by the swirling helps the flue gas to penetrate the activated carbon layer evenly. The amine-modified activated carbon particles capture carbon dioxide. The maintenance structure 200 uses a motor-driven screw 208 to automatically lift and lower the closing cover 201, simplifying the activated carbon replacement process and avoiding the risk of sealing failure caused by manual operation.
[0051] The swirling design increases the contact area between flue gas and activated carbon, improving collection efficiency compared to traditional fixed beds. The vortex airflow continuously washes the surface of the activated carbon, and the tapping action of the rotating plate 307 effectively prevents particle accumulation. The gas detector 203 provides real-time feedback on emission data to ensure compliance with emission standards. When it is necessary to replace the amine-modified activated carbon particles, the motor 205 drives the screw 208 to rotate. Through the threaded engagement of the nut 212 and the screw 208, the closing cover 201 is lifted, and the ring plug 213 disengages from the upper part of the screen cylinder 302. New activated carbon is then transported into the screen cylinder 302 through the inspection port 210. Subsequently, the upper part of the screen cylinder 302 is closed. The electric maintenance structure 200 achieves automated operation, with short replacement time, significantly improving carbon collection efficiency and operational stability.
