In chemical production, the rotary extractor is a commonly used separation and mixing equipment. It works by taking advantage of the difference in the solubility of substances in different solvents to separate the components in a mixture. In this article, we will detail the mixing and separation methods for the rotary disk manifold.
Let's take a look at the basic structure of a turntable extraction column. The turntable extraction tower is usually composed of the tower body, turntable, driving device, sprinkler device, collector and other parts. Among them, the tower body is the shell of the equipment, which plays a supporting and protective role; The turntable is the working part of the equipment, which is used to achieve the mixing and separation of materials; The drive device is the power source that controls the rotation of the turntable; The spray unit is responsible for spraying the solvent to the turntable to achieve the separation of the mixture; Collectors are used to collect the separated substances.
Next, let's take a look at how the turntable extraction column works. When the mixture enters the carousel extraction column, it first passes through a spray unit and mixes well with the solvent. In this process, the components of the mixture are subjected to the solvent to form different solubilities. The mixture then rolls continuously on the turntable, increasing the chance of contact between the components and facilitating the separation. As the turntable turns, the mixture is brought to the height of the tower and then gradually flows downwards and is finally discharged from the outlet. In this process, the components are gradually separated due to differences in solubility in different solvents, resulting in the separation of the mixture.
In the carousel extraction column, the process of mixing and separation is achieved through the following steps:
1.Addition of solvents: Depending on the nature of the mixture and the separation requirements, a suitable solvent is selected and added to the turntable by means of a spray device. The choice of solvent is critical to the separation of the mixture, so it needs to be selected on a case-by-case basis.
2.Addition of the mixture: The mixture to be separated is added to the spinning column. There are many ways to add the mixture, such as one-time addition, batch addition, etc., which need to be selected according to actual needs.
3.Mixing of the mixture: The rotation of the turntable is controlled by the drive device to make the mixture roll on the turntable. In this process, the components of the mixture come into full contact to form different solubilities, which facilitates the separation.
4.Separation of the mixture: As the turntable rotates, the mixture is brought to the height of the tower and then gradually flows downward. In this process, the components are gradually separated due to differences in solubility in different solvents, resulting in the separation of the mixture.
5.Collection of separated substances: The separated substances are collected by means of a collector. There are many ways to collect, such as gravity collection, vacuum collection, etc., which need to be selected according to actual needs.
6.Solvent reuse and recycling: During the separation of the mixture, some of the solvent is left in the extract. In order to improve the utilization rate of solvents, solvents can be recycled through solvent systems.
The rotary column is an efficient and practical mixing and separation equipment. Through the understanding of the working principle and operation process of the rotary extraction column, we can better grasp the application method of this equipment and provide strong support for the production of enterprises. At the same time, through the optimization of solvent selection, mixture handling, and collection of separated substances, we can further improve the separation effect of the rotary column to meet the needs of different industries.
