[0022] Furthermore, the labyrinth ring 7 serves as a seal at the joint, playing a sealing role to prevent the slag dust screwed into the heat exchange cylinder 9 of the slag cooler from leaking out.

[0023] Among them, the slag cooler heat exchange cylinder 9 includes a cylinder inner shell and a cylinder outer shell, and the spiral slag feeding body includes a spiral inner shell 4 and a spiral outer shell 5. The spiral inner shell 4 corresponds to the cylinder inner shell, and the spiral outer shell 5 corresponds to the cylinder outer shell.

[0024] The space between the spiral inner shell 4 and the spiral outer shell 5 is filled with circulating cooling water.
