Description

Technical Field

[0001] This utility model relates to the field of extraction towers, specifically a high-efficiency packed extraction tower. Background Technology

[0002] An extraction tower, also known as a liquid-liquid mass transfer tower, is a commonly used liquid-liquid mass transfer device in industries such as chemical manufacturing, petroleum refining, and environmental protection. Liquid-liquid extraction is a method of mass transfer that uses one or more compound components from a mixture solution to extract them with another liquid (called a solvent, which is immiscible with the solvent in the mixture solution), resulting in separation, enrichment, and purification. This process is called extraction, solvent extraction, or liquid-liquid extraction. The equipment used is called an extractor, and there are single-stage and multi-stage extraction processes, as well as intermittent and continuous extraction processes. Continuous multi-stage extraction uses a tower-type extractor called an extraction tower. Its internal structure utilizes gravity or mechanical action to break a liquid into droplets, dispersing them in another continuous liquid to achieve liquid-liquid extraction.

[0003] For example, the authorized patent with publication number CN213407798U (packed extraction tower with redistributor) includes a tower body, a first feed pipe fixedly connected inside the tower body, a first distributor fixedly connected to the left end of the first feed pipe, a second feed pipe fixedly connected inside the tower body, a second distributor fixedly connected to the right end of the second feed pipe, and a first and a second discharge pipe fixedly connected inside the tower body. This packed extraction tower with redistributor, through the cooperation of a through-channel, a disturbance enhancement pipe, a gas guide pipe, a fixed pipe, and a gas pump, allows inert gas to be pumped into the tower body through the disturbance enhancement pipe, enhancing the disturbance rate of the substances inside the tower, thereby increasing the interphase contact area and improving the extraction efficiency. This achieves the effect of facilitating the improvement of the mass transfer efficiency of the packed tower and solves the problem of low mass transfer efficiency in existing packed extraction towers.

[0004] The existing extraction towers described above are not convenient for adding packing material, making it impossible to replenish packing material during the extraction process. Furthermore, the extracted light liquid cannot be collected after being exported, making it inconvenient to extract quantitatively. In addition, the equipment is relatively bulky and inconvenient to transport. Utility Model Content
