Description

Technical Field

[0001] The utility model relates to the technical field of extraction processing, and specifically relates to a rotary disc extraction tower. Background Art

[0002] The extraction tower, also known as the extraction tower, is a liquid-liquid mass transfer equipment commonly used in chemical industry, petroleum refining, environmental protection and other industrial sectors. Liquid-liquid extraction is a way of mass transfer. One or several compound components in the mixture solution are extracted with another liquid (called a solvent, which is immiscible with the solvent of the mixture solution) to separate, enrich and purify them. This process is called extraction, extraction, liquid-liquid extraction, and solvent extraction process. The equipment used is called an extractor. There are single and multiple extractions, and intermittent and continuous extraction processes. The extractor used for continuous multiple extractions is a tower device called an extraction tower. Its internal structure uses gravity or mechanical action to break a liquid into droplets and disperse them in another continuous liquid for liquid-liquid extraction.

[0003] The equipment used in the liquid-liquid extraction process is used to make the solubility ratio of the compound between the two solvents reach the K value as soon as possible. The method used is to use the difference in the weight of the two solutions, or to add external energy, such as stirring, pulsing, vibration, etc. A liquid is broken into droplets and dispersed in a continuous liquid to improve the mass transfer efficiency. Continuous multiple extraction processes all use tower extraction equipment, that is, extraction towers. There are different structures and types: such as packed extraction towers, sieve plate extraction towers, rotary disc extraction towers, vibrating sieve plate towers, multi-stage centrifugal extraction towers, etc.

[0004] In the turntable extraction tower, there are multiple disks of the same size and spacing strung together by a rotating shaft in the middle, called turntables, which rotate at a uniform speed as the shaft rotates. The turntables are separated by annular disks of the same size and spacing fixed on the tower wall, called fixed disks. A solution (with a lower density) continuously enters the tower from the bottom of the tower, flows upward due to buoyancy, and is broken up and dispersed into droplets by the centrifugal effect of the continuously rotating turntable. Another solvent (with a higher density) continuously enters the tower from the top of the tower, flows downward due to gravity, and fills the entire tower. The broken droplets are dispersed in the continuous solution. Through the contact between the droplets and the solvent, one or several components in the solution are selectively dissolved in the continuous solvent to transfer mass. In the packed extraction tower, the solution is broken up by the action of the filler.

[0005] The light phase and the heavy phase enter the extraction tower from the lower and upper parts of the tower respectively. The two phases are in countercurrent contact in the tower. Under the action of the reciprocating sieve plate, a small droplet dispersed phase is formed. Through the countercurrent contact between the dispersed phase and the continuous phase, one or several components in the material are selectively dissolved in the continuous solvent to carry out mass transfer.

[0006] By utilizing the heterogeneous contact and solubility difference between the mixture and the solvent, the target substance is extracted from the mixture and transferred to the solvent, thereby achieving separation and purification of the substance. In this process, the mixture is introduced from the top of the extraction tower and fully contacts with the solvent in the tower. Since the solubility of different components in the solvent is different, their transfer degree in the solvent is also different, and finally the separation effect is achieved. Then, the solvent phase containing the target substance is separated from the original mixture phase through an appropriate separation device. In addition, physical adsorption, chemical reaction or distillation separation may also occur in the extraction tower, further promoting the separation of substances.

[0007] During the extraction process, it is necessary to test the purity and component content of the initial extraction for analysis. During the first discharge after extraction, sampling is performed to detect whether the extracted liquid is qualified. Based on the results of the test data, it can be determined whether the extraction tower should continue to work. In view of this, a turntable extraction tower is developed. Utility Model Content
