[0038] Working principle of a coal gasification coarse slag dehydration and drying device: First, the user connects the centrifugal device 1 to the coarse slag discharge port of the coal gas device through a pipeline. When the coarse slag is discharged into the centrifugal device 1, it is first dehydrated. After the dehydration is completed, it is then discharged into the mixing box 3. And during the discharging process, due to a large amount of dust and other impurities carried by the coarse slag itself, a large amount of dust is easily generated in the mixing box 3. At this time, the dust removal component 4 can be started to suck out these impurities from the inside of the mixing box 3. At this time, the drying device body 2 and the dust removal component 4 are started to mix and heat the coarse slag at the same time for easy use.
