Industrial Sieve Plate Extraction Columns Or Towers

Wuxi Hongdinghua Chemical Equipment Co.,Ltd is China manufacturer & supplier who mainly produces Industrial Sieve Plate Extraction Columns Or Towers with many years of experience.  Wuxi Hongdinghua Chemical Equipment Co., Ltd.(HDH) is also a professional manufacturer of design and production of extraction towers. Sieve plate extraction towers are used for separating or synthesizing complex mixed liquids.

In industrial production, there are occasions where multiple solvents need to be mixed and used, and the mixed liquid of these multiple solvents also faces the situation of not being able to continue to be used after long time running or processing. However, one or more solvents in this multi solvent mixed liquid, due to their high value, will cause resource waste and pollution if discharged directly. It does not meet the requirements of environmental protection and conservation, and will also increase the cost of subsequent treatment. Moreover, it is difficult to be physically separated the valuable parts of this liquid mixed with multiple solvents. At this point, another or a series of methods must be used to separate the solvent through specially designed equipment, and the extraction separation must be carried out through an extraction tower. The sieve plate extraction tower is such a separation equipment.

The principle of a sieve plate extraction tower is to separate the mixed liquid in layers according to its different solubility and precipitation characteristics, thereby accurately separating the mixed liquid into various liquid components.

Features and Applications of Sieve Plate Extraction Tower

The flow structure of the liquid-liquid two-phase flow in the sieve plate extraction tower has a significant impact on mass transfer efficiency, and the flow structure of the continuous phase is closely related to the structure of the tower's internal components. Sieve plate extraction tower has a wide range of applications in fine chemicals, pharmaceuticals, environmental protection, and other fields due to its large processing capacity, simple structure, and low cost.

Sieve plate extraction tower details

Sieve plate extraction tower is a commonly used liquid-liquid mass transfer equipment in industrial such as chemical industry, petroleum refining, and environmental protection. Liquid-liquid extraction is a method of mass transfer, in which one or several compound components in a mixture solution are extracted using another liquid (called a solvent, which is not miscible with the solvent of the mixture solution) to separate, enrich, and purify them. This process is called extraction, a solvent extraction process. The equipment used is called an extractor, which has one and multiple extractions, gaps, and continuous extraction processes. The extractor used for continuous multiple extractions is a tower type equipment called an extraction tower. The Sieve Plate Extraction tower internal structure is using the effects of gravity to break a liquid into droplets and disperse them in another continuous liquid for liquid-liquid extraction.

It is necessary to provide HDH following technical data and related parameters when HDH is designing a Sieve Plate Extraction Tower that can meets customer’s requirements.

During the extraction communication process, it is necessary to know the following data:

1. Raw Material density, extractant density; 

2. After knowing the processing capacity(Amount), ratio of material to extractant , the diameter of the Sieve plate extraction tower can be determined; 

3. Have you conducted a small test or the current operation status of the kettle type? The main purpose is to know how many extraction cycles needed that can meet the process requirements, so that the height of the extraction section can be determined; 

4. Material layering time, which can calculate the cylinder volume of the clarification section; 

5. Is there any emulsification phenomenon? If so,a sewage outlet should be considered in layered section; 

6. What is the pH value of the material and its characteristics, making it convenient for selecting equipment materials(proper material to build the Sieve Plate Extraction Tower;
