Description

Detachable cleaning sieve plate extraction tower Technical Field The utility model relates to the technical field of extraction towers, and particularly discloses a screen plate extraction tower capable of being cleaned in a detachable mode. Background Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that utilizes the difference in solubility or partition coefficient of each component in a mixture in mutually immiscible (or slightly soluble) solvents to achieve component separation. The method extracts target substances from solid or liquid mixtures through transfer of solutes between two solvents, and is widely applied to the industrial fields of chemistry, metallurgy, food, petroleum refining and the like. The sieve plate extraction tower is used as core equipment for liquid-liquid extraction, and light liquid and heavy liquid form countercurrent contact in the tower body through the combination of a plurality of layers of sieve plates and fillers, so that mass transfer is completed. The sieve plates of the traditional sieve plate extraction tower are usually fixed on the inner wall of the tower body through fasteners, and filler is filled between adjacent sieve plates to strengthen the mass transfer effect. However, when the screen plate needs to be cleaned and the filler needs to be taken out, the bolts need to be disassembled layer by layer from top to bottom, and the screen plate and the filler need to be taken out in sequence, namely, when one layer of screen plate is disassembled, the filler below the screen plate needs to be dug out first, and then the lower screen plate is disassembled. The mode of layer-by-layer disassembly is complex in operation and long in time consumption, and because the filler is tightly filled in the tower body, the filler is required to be manually dug out layer by layer to be taken out, so that the cleaning difficulty and the operation intensity are further increased. Thus, a need exists for a screen extraction column that can be removed for disposal to address this problem. Disclosure of utility model The utility model provides a detachable cleaning sieve plate extraction tower, which is simple and convenient in cleaning operation of a plurality of layers of sieve plates through an innovative structural design, and meanwhile, the defect of digging traditional fillers layer by layer is avoided, and the operation difficulty and the operation strength of taking out the fillers are obviously reduced.
