In this way, the wet flue gas entering the fixed tube 32 can be diverted, thereby improving the condensation effect of the wet flue gas.

[0036] As a technical optimization solution of the utility model, an electric hydraulic rod 61 is bolted to the bottom surface of the water receiving pipe 35, and the output end of the electric hydraulic rod 61 extends to the inside of the water receiving pipe 35.

The wet flue gas can be diverted through the diverter plate 51 and the diverter hole 52. The wet flue gas moves to the fixed pipe 32 and contacts the fixed pipe 32. The wet flue gas condenses into water when it is cooled. The water moves downward to the water receiving pipe 35 by its own gravity. During the movement of the wet flue gas inside the fixed pipe 32, the guide cover 41, the fixed rod 43 and the diverter block 44 are all cooled. The wet flue gas contacts the guide cover 41 first and then the diverter block 44, which slows down the movement speed of the wet flue gas inside the fixed pipe 32, so that the moisture in the wet flue gas is fully condensed, and the dehydrated flue gas flows back to the flue body 1, and the water-absorbing sponge 64 absorbs the condensed water and blocks the drain pipe 36 to prevent the wet flue gas from being discharged from the drain pipe 36. The electric hydraulic rod 61 is started to pull the pressure plate 62 to squeeze the water-absorbing sponge 64. At this time, the moisture is discharged through the through hole 63, and then the moisture is discharged through the drain pipe 36. In this way, the wet flue gas is efficiently dehydrated.
