Abstract

The invention relates to the technical field of chemical engineering, and discloses a separation device for preparing o-xylene by separating mixed xylene, wherein the separation device comprises a feeding tank; the top end of the feeding tank is fixedly communicated with a separation tank, and the bottom end of an inner cavity of the separation tank is fixedly provided with a fixed block; and a movable rod located in the separation tank is movably mounted at the top end of the fixed block. According to the separation device for preparing o-xylene separated from mixed xylene, a flow deflector enters a temporary storage tank below to complete collection, meanwhile, o-xylene can push impellers to rotate when rising, the movable rod is driven to rotate through rotation of the multi-stage impellers, and an arc-shaped rod at the top end of a main shaft is driven to rotate; due to the fact that the top end of the arc-shaped rod make contact with the inner side face of a top cover, the inner side face of the top cover is cleaned, remaining o-xylene is scraped off, the remaining o-xylene enters the temporary storage tank through the flow deflector and is finally discharged through a discharging pipe, and thus the advantage that o-xylene is fully collected is achieved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a separation device for the preparation of mixed xylenes and o-xylenes. Background technique [0002] Xylene is an organic compound with a molecular formula of C8H10. It is a colorless transparent liquid. It is a product in which two hydrogens on the benzene ring are replaced by methyl groups. There are three isomers, ortho, meta, and para. In industry, xylene That is to say a mixture of the above isomers. Colorless transparent liquid. Has a special smell of aromatic hydrocarbons. It is a mixture of three isomers consisting of 45%-70% m-xylene, 15%-25% p-xylene and 10%-15% o-xylene. It is easy to flow and can be mixed with absolute ethanol and ether Miscible with many other organic solvents. Xylene has a pungent odor, is flammable, can be mixed with ethanol, chloroform or ether, and is insoluble in water. The boiling point is 137-140°C. Xylene is a low-toxic chemi...
