Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a liquid ammonia distillation tower with a cleaning and recycling function. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. By utilizing the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, the light components in the liquid phase are transferred to the gas phase, and the heavy components in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. The distillation tower is also a mass transfer and heat transfer device that is widely used in petrochemical production. The distillation tower of the prior art usually obtains liquid ammonia by pressurizing or cooling gaseous ammonia.

[0003] However, the prior art lacks the function of accelerating volatilization. In actual use, when the inside of the distillation tower is pressurized, the internal material cannot volatilize quickly and evenly form liquid and gas, resulting in the inability of the prior art to quickly shape the material, resulting in low efficiency of the prior art.

[0004] In addition, the existing technology lacks the function of cleaning the inner wall. In actual use, it is impossible to completely remove all the dirt on the inner wall by just washing the inner wall with water. When there is too much residual material on the inner wall, it will cause impure mixing between the materials, resulting in a low output yield. Utility Model Content

[0005] The utility model aims to provide a liquid ammonia distillation tower with a cleaning and recovery function to solve the problems raised in the above background technology.

When in use, the stirring blade is fixed by the fixed column, and the external power supply of the motor drives the fixed column to rotate. The stirring blade rotates inside the device to stir the gaseous and liquid bodies inside for volatilization, and then the slot holes are opened to facilitate the rapid flow of the gaseous and liquid bodies, thereby achieving the effect of stirring evenly and accelerating volatilization, avoiding the situation that when the distillation tower is pressurized, the internal materials cannot be quickly volatilized and uniformly formed into liquid and gaseous states, resulting in the inability of the prior art to quickly shape the materials, resulting in low efficiency of the prior art.
