At the same time, the evaporated water contacts the smoke in the exhaust gas, so that The smoke and dust are mixed with water for easy sedimentation. As the exhaust gas moves along the first baffle plate 22 and then turns and moves downward, the exhaust gas moves downward along the side wall of the cover plate 27. Under the action of gravity, part of the smoke and dust falls on the surface of the cover plate 27. The cover plate 27 is funnel-shaped. The gap between the cover plate 27, the first baffle plate 22 and the cylinder 21 is getting smaller and smaller.

Inside the liquid separator 4, after the solution and the gas are separated by the gas-liquid separator 4, the gas is discharged, and the solution is sprayed on the surface of the packing layer 54 through the spray pipe 55. At this time, the steam is sprayed upward through the steam spray pipe 53 into the inside of the packing layer 54. The presence of the packing greatly increases the contact area between the steam and the liquid phases, making the mass transfer and heat transfer process more efficient; as the gas or steam rises, the CO2 in the liquid is heated and evaporated and discharged through the connecting pipe 57, and the vacuum pump 56 operates to generate suction inside the connecting pipe 57 to quickly extract the CO2, and the alkanolamine solution moves downward through the packing layer 54 and re-enters the inside of the liquid storage tank 33 for recycling.

The accumulated water moves downward through the first filter cartridge 82 and the dredging pipe 83, and the water flows downward and contacts the top blocking block 85. The water continues to flow downward through the blocking block 85 and enters the top installation pipe 88 and the third filter cartridge 87. Through the third filter cartridge 87, the water flows into the interior of the packing layer 54 again, moves downward and contacts the steam; when the packing layer 54 around the third filter cartridge 87 is also blocked, water gradually accumulates in the third filter cartridge 87 and the installation pipe 88, and the accumulated water flows through the installation pipe 88 and the The dredging pipe 83 flows downward again. Similarly, the accumulated water moves downward along the dredging pipe 83 and enters the interior of the next installation pipe 88.
