Description

Technical Field

[0001] The utility model relates to the technical field of distillation equipment, in particular to a distillation tower of chemical separation equipment. Background Art

[0002] Distillation is a distillation method that uses reflux to separate liquid mixtures into high-purity solutions. It is the most widely used liquid mixture separation operation in industry. A distillation tower is a tower-type vapor-liquid contact device for distillation. There are two main types: plate towers and packed towers. The basic principle of a distillation tower is to partially vaporize and partially condense a liquid mixture multiple times, using the different volatilities of the components therein to achieve a unit operation for separation.

[0003] The Chinese utility model patent (authorization announcement number: CN215900959U name: a multi-stage chemical distillation tower with fireproof function) includes a distillation tower body, a loading frame fixedly connected to the top side of the distillation tower body, and a circular ladder connected around the outer periphery of the distillation tower body. The top of the distillation tower body is connected to a circular water pipe through a mounting mechanism, and the bottom of the circular water pipe is fixedly connected to multiple water delivery pipes distributed around the center of the circular water pipe, and the bottom ends of the water delivery pipes are fixedly connected to nozzles, the top of the loading frame is fixedly connected to a water tank, and a water pump is fixedly installed on the inner bottom of the water tank. The utility model can monitor the top of the distillation tower body in real time through a detection mechanism. When the temperature is too high and smoke is detected, the processor receives a signal and sends a pulse signal to the water pump to make it work. The nozzle sprays water to extinguish the fire on the top of the tower, which can eliminate the hidden danger of fire, thereby facilitating the long-term use of the distillation tower. However, in the process of steam condensation and liquefaction, part of the steam on the top of the inner tower will liquefy and repeatedly flow back into the solution, reducing the distillation efficiency and prolonging the preparation and separation time.
