Distillation device for purifying organic matters

The present invention relates to a distillation apparatus for organic matter purification, the distillation apparatus comprises: a heating part, a mixed liquid is heated through the heating part to form steam, and the heating part is provided with a steam outlet for steam outflow and a flow guide wall located at the top of the steam outlet; the drainage wall is arranged above the air outlet, the height of the drainage wall and the height of the flow guide wall are sequentially reduced from the middle of the drainage wall to the peripheral side, and the drainage wall has a cooling function; and the liquid-permeable interlayer is connected between the drainage wall and the flow guide wall in a surrounding manner. Through the refrigeration effect of the drainage wall and the matching of the shape of the drainage wall, components to be separated make contact with the drainage wall to be liquefied after forming steam, so that the components are accumulated on the liquid-permeable interlayer and are deposited on th
