[0021] The working principle of the present utility model: First, the flue gas to be treated is discharged into the inside of the box body 1 through the intake pipe 2. When the flue gas enters through the intake pipe 2, the fixed rod inside the intake pipe 2 fixes the connecting rod 13. The plurality of rotating plates 14 arranged in a crosswise manner on the connecting rod 13 can initially slow down the flow rate of the flue gas;

[0022] When the flue gas enters the inside of the box body 1, by contacting the flue gas with the condensing plate 15, the moisture in the flue gas is initially treated. The plurality of condensing plates 15 are arranged in a crosswise manner, which can not only slow down the flow rate of the flue gas again, but also make the flue gas better contact with the condensing plate 15. Finally, the moisture in the flue gas is secondarily treated through the condensing pipes 18, improving the treatment effect of the device on the moisture in the flue gas. The condensing pipes 18 are also arranged in a crosswise manner, making it possible to better contact the flue gas and treat the moisture in the flue gas;

[0023] The treated flue gas is discharged through the outlet pipe 3.

The nano-coating provided on the surface of the convex block 11 can prevent water from being adsorbed on the surface of the convex block 11, so that the water drops into the collection tank 10, better collecting the moisture in the flue gas. The liquid level sensor 8 inside the collection box 5 can detect the water inside the collection box 5, facilitating the rapid discharge of the collected water after it is full. The model of the liquid level sensor 8 is set as CYW11. Opening the door 4 on one side of the box body 1 facilitates the cleaning and maintenance of the mechanism inside the box body 1.

[0025] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly.
