Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to an upper water-cooled wall cooling device. Background Art

[0002] In the prior art, a modified or newly built denitrification reactor will add a bypass flue on the boiler side wall at the front end of the denitrification reactor. Part of the high-temperature flue gas in the boiler is led out of the boiler through the bypass pipe to ensure that the flue gas temperature entering the denitrification reactor is within the design range, thereby ensuring the efficiency of denitrification. The boiler side wall is provided with an opening connected to the bypass pipe, and the high-temperature flue gas enters the bypass pipe through the opening and is discharged from the boiler. A large number of vertically arranged water-cooled wall pipes are arranged outside the opening, and multiple water-cooled wall pipes are arranged in parallel and spaced apart. The high-temperature flue gas in the furnace can only enter the bypass flue through the gaps between the water-cooled wall pipes.

Moreover, the cooling effect is not good relying solely on water cooling. An upper water-cooled wall cooling device is needed to solve this problem. Utility Model Content
