The utility model discloses a centrifugal defroster solves the problem that difficulty, the unable less droplet of desorption are installed, are maintained to current device. The utility model discloses an equilateral hexagon barrel, the centrifugation combination piece that sets up lower part in equilateral hexagon barrel is organized to and set up outside equilateral hexagon barrel the water pipe assembly that washes of bottom, still be equipped with and wash the washing terminals that water pipe assembly is linked together and runs through centrifugation combination piece group in the equilateral hexagon barrel. The flue gas by the utility model discloses the bottom gets into, upwards runs through the outflow, reaches dust removal, defogging effect through the centrifugation combination piece group that sets up, the flue gas of centrifugation combination piece group of flowing through simultaneously forms the whirl in equilateral hexagon barrel, cause remaining most dirt in the flue gas, fog to tack under on the wall to it is dirty in the thick liquid pond along with section of thick bamboo wall.
