[0002] With the intensification of the greenhouse effect, carbon dioxide emissions have begun to attract widespread attention. In order to alleviate the greenhouse effect, more and more factories have begun to capture, store and recycle carbon dioxide, which requires the use of a skid-type device for carbon dioxide capture. Therefore, the existing skid-type device based on carbon dioxide capture has been continuously innovated and developed. It can be seen that the current carbon dioxide capture device basically meets people's needs, but there are still some problems.
[0003] Existing carbon dioxide capture equipment usually recovers the high-concentration carbon dioxide gas emitted by factories, dissolves the carbon dioxide in the mixed gas through a solvent, and then purifies it.
[0004] However, when the device sprays the capture reagent on high-concentration carbon dioxide gas, the gas is relatively dispersed and the spraying structure finds it difficult to spray the capture reagent completely into the reaction box. As a result, the capture reagent fully dissolves the carbon dioxide in the mixed gas, thereby reducing the capture effect of the device. Therefore, a skid-type device based on carbon dioxide capture is urgently needed to solve the above problem. Utility Model Content

When performing the capture step, the servo motor 9 is powered on, and the output end of the servo motor 9 drives the stirring blades 10 to rotate. When the stirring blades 10 rotate, the transmission belt 11 at the bottom is driven to rotate, thereby driving another group of stirring blades 10 to rotate.

[0037] Working principle: when using a skid-type device based on carbon dioxide capture, the high-concentration carbon dioxide mixed gas is first injected into the first connecting pipe 12 through the feed pipe 6, and finally injected into the first processing box 2 through the first connecting pipe 12, and then the capture reagent is injected into the conveying groove 4 through the first water pump 3 and discharged through the nozzle 5, so that the captured gas is in contact with the high-concentration carbon dioxide mixed gas, and the high-concentration carbon dioxide mixed gas is integrated into the captured gas, while the rest of the high-concentration carbon dioxide mixed gas is discharged through the gas pipe 18, and the capture reagent with carbon dioxide is transported to the second processing box 15 through the second connecting pipe 22, and the second processing box 15 is heated by injecting water vapor into the connecting groove 17, so as to heat the capture reagent with carbon dioxide, separate the carbon dioxide from the capture reagent, and finally transport the carbon dioxide to the storage box 19 through the gas pipe 18.
