The utility model provides a coil type sulfur melting device, which relates to sulfur fusion and acid making technology. The device includes the sulfur melting pot body, the heating coil, the impeller shaft, the stirring blade and the driving motor. The heating coil is located near the inner wall of the sulfur melting pot, and the impeller is set up with three groups of blades, which are located in three positions in the upper, middle and lower parts of the impeller shaft, and the agitator is driven clockwise by the driving motor at the top. When the steam enters the inlet of the coil, the sulphur powder or the dry sulfur containing material is slowly added to the sulphur melting pot, and the driving motor is opened when the bottom material exceeds the lowest part of the blade, and then the material is added in turn, then the material is discharged from the bottom outlet and sent to the next section after all the melting. The steam coil is inside the sulfur melting kettle, so that the sulfur in each part of the sulfur melting kettle is closer to the coil tube, so that the heat is even more uniform. At the same time, the sulfur in the sulfur melting pot can also make the heating more uniform and enhance heat transfer under stirring. And when the equipment needs to be repaired, the condensate can be condensed into the coil pipe to cool down.
