[0010] The above scheme involves introducing high-temperature flue gas into the lower chamber through the intake pipe. The cooling water in the lower chamber comes into contact with the high-temperature flue gas and cools it down. At the same time, it adsorbs some of the dust particles in the high-temperature flue gas. Subsequently, the flue gas is discharged from the water in the lower chamber and comes into contact with the heat sink. Meanwhile, two cooling fans operate to transfer the heat from the heat sink located in the mounting frame to the air guide shroud. The conveying pipe then delivers the hot air to the waste heat recovery equipment.

[0014] The beneficial effects of this utility model are as follows:

[0015] The intake pipe delivers high-temperature flue gas into the lower chamber, where cooling water comes into contact with and cools the flue gas. Simultaneously, the cooling water absorbs some dust particles from the flue gas. The flue gas then exits through the water in the lower chamber and comes into contact with the heat sink. Two cooling fans operate, transferring heat from the heat sink within the mounting frame to the air duct. The hot air is then transported to the waste heat recovery equipment via a delivery pipe. This process ensures that the high-temperature flue gas fully contacts the cooling water, and the copper heat sink further cools the flue gas, resulting in rapid cooling and improved practicality.
