Problems solved by technology

[0003] However, in the application process of the current pedal-packed rectification tower, when the material is rectified, the heat loss is large, which cannot be recycled reasonably, resulting in a waste of energy. The contact area is not perfect enough, so the efficiency of rectification needs to be improved

Abstract

The invention relates to the technical field of molecular distillation, and discloses an improved tray-packed rectification tower for molecular distillation, which includes a tower body, a discharge heat exchanger is arranged on one side of the bottom end of the tower body, and the bottom of the tower body There is a reboiler on the other side of the end, and a feed heat exchanger is installed outside the middle of the tower body, and the middle part of the top of the tower body is connected with a gas phase discharge pipe, and the other end of the gas phase discharge pipe is connected to a top heat exchanger. , the inside of the tower body is provided with an inner chamber, the inside of the inner chamber is surrounded by a first circulation pipe, the inside of the tower body is distributed from bottom to top with several trays, and the inside of the tower body runs through the center of the trays. central tube. The invention realizes the recovery and utilization of heat, facilitates the heat preservation of the tower body, avoids the heat loss of the tower body, and can preheat the materials, and utilizes the cooperation of the central tube and the gas ring to facilitate the formation of several steam layers in the tower body , to ensure better contact between the steam and the material, and improve the rectification efficiency of the material.

Description

technical field [0001] The invention relates to the technical field of molecular distillation, in particular to an improved tray-packed rectification tower for molecular distillation. Background technique [0002] The rectification tower is a tower-type gas-liquid contact device for rectification. Utilizing the different volatility of each component in the mixture, that is, the property that the vapor pressure of each component is different at the same temperature, the light components (low boilers) in the liquid phase are transferred to the gas phase, and the light components in the gas phase are transferred to the gas phase. The heavy components (high boilers) are transferred to the liquid phase, thus achieving the purpose of separation. [0003] However, in the application process of the current pedal-packed rectification tower, when the material is processed through rectification, the heat loss is large, which cannot be recycled reasonably, resulting in a waste of energ...
