[0001] The invention relates to the application field of quenching towers, in particular to a quenching tower with a detachable spray pipe. Background Art

[0002] The currently used large quench towers have a spray pipe inserted at the top of the quench tower, but it is found during use that the cooling effect of the space above the quench tower is better, while the cooling effect of the space below the tower is poor;

[0003] In addition, the spray pipe is installed on the side wall of the quenching tower. However, it is found during use that once the spray pipe or nozzle fails, the spray pipe cannot be quickly disassembled for maintenance. Maintenance workers are required to hang the spray pipe from the top of the tower body into the tower to repair it. This maintenance process is relatively dangerous, and the environment inside the tower can easily cause physical harm to maintenance workers.
