Description

Technical Field

[0001] The utility model relates to the technical field of carbon capture, in particular to a carbon dioxide separation and recovery device for carbon capture. Background Art

[0002] Carbon capture is the process of capturing carbon dioxide from industrial production by various means and then storing or utilizing it. It captures carbon dioxide released into the atmosphere, compresses it, and then compresses it back into depleted oil fields and natural gas fields or other safe underground places. It is an important waste gas treatment and environmental protection process and is becoming increasingly widely used.

[0003] The existing carbon dioxide separation and recovery equipment for carbon capture has the following disadvantages when in use: adsorption is a commonly used method for separating and recovering carbon dioxide, and generally uses activated carbon or other adsorption materials to adsorb and isolate carbon dioxide in the exhaust gas, and then recycle it. When using the existing adsorption carbon dioxide treatment equipment, it is necessary to regularly desorb carbon dioxide to ensure the adsorption performance of the adsorption material and treat the desorbed carbon dioxide. The existing carbon dioxide desorption treatment process is time-consuming and cannot be operated continuously. For this reason, we propose a carbon dioxide separation and recovery device for carbon capture. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

When the mounting frame is installed inside the isolation cover, its top pulley is inserted into the annular guide groove to ensure that the mounting frame can run smoothly.

[0008] Furthermore, teeth are provided at the bottom of the mounting frame, a motor is installed on one side of the body surface and a gear meshing with the teeth is installed at the power output end of the motor; when the motor is running, its power end drives the gear to rotate after passing through the reduction assembly, and during the rotation of the gear, the mounting frame cooperates with the teeth to cause the mounting frame to rotate slowly inside the isolation cover.

[0009] Furthermore, a fan is installed at one end inside the machine body and the exhaust end of the fan faces one side of the isolation cover; the fan plays a role in guiding the flow direction of the airflow so that the airflow passes through the inside of the machine body.

[0010] Furthermore, rubber pads are bonded to the connection points on both sides of the surface of the mounting frame; the rubber pad structure can ensure the sealing of the connection points after the mounting frames are butt-jointed.

[0011] Compared with the prior art, the utility model has the following beneficial effects: an isolation cover is provided inside the machine body and the mounting frame can drive the activated carbon layer to rotate continuously along the inside of the isolation cover. When the waste gas to be treated enters from one side of the machine body and passes through the mounting frame, the internal carbon dioxide is adsorbed by the activated carbon layer. As the mounting frame moves, the activated carbon layer adsorbing carbon dioxide moves to a position close to the heater. The high temperature generated by the heater heats the activated carbon layer. At the same time, the external adsorption device connected to the exhaust pipe can absorb the carbon dioxide separated by the heat from the activated carbon layer and further process it, thereby realizing the desorption of the activated carbon layer. The desorbed activated carbon layer is input into the mounting frame again. In this way, continuous adsorption and desorption of carbon dioxide are achieved, the continuity and overall efficiency of exhaust gas treatment are improved, and the activated carbon layer passes through the interior of the machine twice to improve the adsorption quality of carbon dioxide; docking holes are provided on both sides of the surface of the mounting frame near the connection.
