Specifically, the desorption structure 20 includes a multi-layer distributor, the distributor includes a plate 21, a plurality of through holes 22 are arrayed on the plate 21, the aperture ratio of the through holes 22 is 15.6%, and the through holes 22 of two adjacent layers of distributors are staggered, i.e. the through holes 22 of the upper layer of distributor are not right below the through holes 22 of the lower layer of distributor, but are staggered, so that the water travel can be increased, the residence time of the water can be increased, and the desorption of CO can be enhanced 2 Is effective in (1).
The liquid distributors are uniformly welded in the box body 10, gas is sent in from the bottom of the tower by a fan, liquid is sprayed on the next layer of liquid distributor through the distributors at the water inlet 11, the liquid is dispersed into a film on the surface, and the film flows down through gaps among the liquid distributors and can possibly drop into liquid drops, so that the surfaces of the two layers of liquid distributors become mass transfer surfaces with two phases of gas and liquid in contact.
CO 2 The solubility in water is in accordance with Henry's law, i.e. the solubility of a gas in water is proportional to the partial pressure of the gas above the surface of the liquid at a certain temperature, so long as the CO in the gas above the surface of the liquid 2 Is small in partial pressure of CO in water 2 Will escape from the water, a process known as desorption.
CO in air 2 Is present in a small amount and has a partial pressure of about 0.03% of atmospheric pressure. Therefore, air is commonly used as CO 2 The medium of the removing device is sent into CO through a blower 2 The bottom of the removal device, together with the escaping CO, after the surface of the liquid distributor is fully contacted with the water 2 Together with CO from the top of the column 2 The water enters from the upper part of the tower body and is sprayed down by a liquid distributor, and the water is fully contacted with air on the surface of the liquid distributor to escape CO 2 And then flows out from the lower water outlet 12, thereby realizing solid CO 2 Is removed.
The wind power system 30 is connected with the box body 10, and desorbed carbon dioxide is taken away by the wind power system 30, so that the purpose of removing carbon dioxide in the water body is achieved. And the water body after removing the carbon dioxide can reenter the water body circulation system for recycling.

Specifically, the wind generating device 31 may be a positive pressure fan, for example, a blower; in this case, an air outlet 33 is formed in the case 10 to discharge the desorbed carbon dioxide.
Specifically, the wind power generation device 31 may be a negative pressure fan, for example, a vacuum pump; in this case, carbon dioxide is sucked into the duct 32 from the tuyere 33, and is discharged out of the case 10 through the duct 32.
Compared with a positive pressure fan, the negative pressure fan has more uniform wind force effect at the air port 33, and the negative pressure environment is favorable for further reducing the partial pressure of carbon dioxide so that the carbon dioxide can escape more easily.
