In rectifying tower, when mixture is heated and vaporized, it enters tower, and gas-liquid contact is carried out on tray (or filler). The content of volatile component in gas phase is higher, and the content of difficult volatile component in liquid phase is higher. With the upward flow of gas phase, the downward flow of liquid phase, on each tray (or each section of filler), heat and mass exchange between gas and liquid phases are carried out, so that multiple partial vaporization and partial condensation are realized.

The support frame is fixedly connected to the outer wall of the rectifying tower body. The bottom end of the rectifying tower body is fixedly connected to one end of the connecting pipe. The other end of the connecting pipe is fixedly connected to the collecting and processing pipeline. As a further scheme of the utility model, the collecting and processing pipeline comprises a pipeline body, a connecting hole, V-shaped grooves and a homogenizing device.

The stirring shafts are symmetrically arranged on the other end of the rotating shaft. Each stirring shaft is fixedly connected to filter cotton. As a further scheme of the utility model, the connecting pipe comprises a connecting pipe body, a fixed ring and an activated carbon filter element. The fixed ring is fixedly connected to the inner wall of the connecting pipe body. The activated carbon filter element is fixedly connected to the inner wall of the fixed ring.
