[0002] Thermal power generation is one of the important ways of generating electricity at present. Slag is produced in the process of thermal power generation. The slag cooled after waste heat recovery is transported to the slag bin and then discharged from the bottom of the slag bin. The slag transport vehicle transports the slag discharged from the bottom of the slag bin.

[0003] Since the slag is relatively dry, smoke and dust will be generated during the falling process, which will not only cause harm to on-site workers, but also pollute the surrounding environment. Utility Model Content
