| description | The utility model relates to a dichlorobenzene rectification column structure, which comprises a rectification column, a condenser and a reflux tank. The top of the rectification column is communicated with the condenser with an exhaust pipe, the bottom of the condenser is communicated with the reflux tank through a liquid phase pipe, the reflux tank is communicated with the upper portion of the rectification column through a reflux pipe, and a lift pump is installed on the reflux pipe. The dichlorobenzene rectification column structure is characterized in that the liquid phase pipe consists of a steel pipe lined with a polytetrafluoroethylene pipe. Since the liquid phase pipe is formed of the steel pipe lined with the polytetrafluoroethylene pipe according to the polytetrafluoroethylene pipe lining technology, and the polytetrafluoroethylene pipe is reliable and excellent in wear resistance, high-corrosive gas and liquid at high temperature can be delivered, and problems about corrosion resistance of the rec |
