| titleOfInvention | A kind of tetrahydrofuran purification device |
| abstract | The application discloses a tetrahydrofuran purification device, comprising a crude tetrahydrofuran storage tank, a rectification kettle is connected to the crude tetrahydrofuran tank, a stirring shaft is arranged in the rectification kettle, a motor is arranged above the stirring shaft, and the stirring A stirring rod is arranged below the shaft, a heating assembly and a temperature detection device are arranged in the rectification kettle, a steam outlet pipe is arranged on the side of the rectification kettle, and the steam outlet pipe is connected with a filter cavity, and the filter cavity is provided with There is a pervaporation membrane assembly, and a condensation tank is connected to the filter cavity. In the present application, the crude tetrahydrofuran is sent to the rectification kettle, and the crude tetrahydrofuran is heated in the rectification kettle, and the heating temperature is controlled so that the tetrahydrofuran becomes a vapor state, and the crude tetrahydrofuran is filtered out through the pervaporation membrane assembly in the filter chamber. Finally, condensation is carried out in the condensation tank to obtain tetrahydrofuran with higher purity, which can not only improve the purity of crude tetrahydrofuran during use, but also is more convenient and flexible to use. |
