Film flash distillation tower

Abstract

The invention discloses a film flash distillation tower. The film flash distillation tower comprises an evaporator, the left end of the evaporator communicates with a raw material inlet, the top of the interior of a tower body is fixedly connected with a heat pipe cooler, and a stirring assembly is arranged in the evaporator. According to the film flash distillation tower, through cooperation of the evaporator, the tower body and the stirring assembly, and when the raw materials are heated and flashed, a scraping plate and a sliding rod can abut against the inner wall of the evaporator and rotate, so that raw materials are prevented from adhering to the wall during heating, the influence on the heating efficiency is avoided, the raw materials can be stirred in a turbulent flow manner, theuniformity of the internal temperature of the raw materials is further improved; and through cooperation of the evaporator, the tower body, the heat pipe cooler and the rotating assembly, the device can drive the polyhedral ball to continuously rotate through the spiral blades, the contact area between the vaporized raw material and the filler is increased, the number of vaporization times of theraw material is increased, and the yield and quality of the distilled raw material are improved.

Description

technical field [0001] The invention relates to the technical field of thin film flash distillation towers, in particular to a thin film flash distillation tower. Background technique [0002] The rectification tower is a tower-type gas-liquid contact device for rectification. It uses the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, so that the vapor pressure of the components in the liquid phase is different. The light components are transferred to the gas phase, while the heavy components in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. Distillation column is also a mass transfer and heat transfer device widely used in petrochemical production. [0003] In the thin film flash rectification tower in the prior art, the raw material is easy to adhere to the wall during heating, which affects the heating efficiency. Larger contact ar...
