PURPOSE: An evaporative type sulfur purifier is provided to maximize the evaporating efficiency of liquid sulfur by lowering the height of the liquid sulfur filled in an evaporating container by using a multi-staged evaporating container. CONSTITUTION: An evaporative type sulfur purifier includes a multi-staged evaporating container(100), a heater, and a plurality of liquid sulfur storing protrusions. The container is filled with sulfur. The central bottom side of the container is higher than the outer bottom side of the container. The heater is attached to the outer bottom side of the container to heat the container. The liquid sulfur storing protrusions are concentrically upwardly expanded from the bottom side of the container. The heater is a positive temperature coefficient heater. The container is sealed with a sealing container(200) and a cover(201).
