Title:
DISTILLATION APPARATUS AND ADDITIVE MANUFACTURING EQUIPMENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/084493
Kind Code:
A1
Abstract:
The present invention relates to a distillation apparatus for fractionating impurities from a raw material by a fractional distillation method using a boiling point difference to modify the raw material, the distillation apparatus comprising: a reactor having an internal space capable of heat treating the injected raw material and moving the separated impurities; and an impeller installed in a lower part of the reactor and including a blade rotating while supplying hot air into the reactor. Thus, according to an embodiment of the present invention, since the hot air is supplied while the impeller is rotating, the hot air, which is a heat source, can be uniformly transferred to the inside of the distillation apparatus. As a result, the raw material, which is an object to be treated, uniformly contacts the hot air, which is a heat source, thereby improving the separation efficiency of impurities. Therefore, since the content of impurities is low, a high-quality additive can be manufactured.
