Abstract

The invention discloses an energy-saving fractionation device for xylene production, relating to the technical field of xylene fractionation, comprising a first box and a second box installed at the bottom of the first box, the second box The bottom is rotatably installed with a screw rod installed in the vertical direction, the top of the first box is fixed with a drive mechanism connected to the top of the screw rod, the top thread of the screw rod is sleeved with a sleeve, and the two sleeves The ends are respectively fixed with a first circular plate and a second circular plate, and the peripheral outer walls of the first circular plate and the second circular plate are close to and not in contact with the inner walls of the first box body and the second box body, A vertical pipe is fixed between the first circular plate and the second circular plate, and multiple sets of circularly distributed adsorption plates are fixed on the peripheral outer wall of the vertical pipe. The present invention can realize that the adsorption plate fully absorbs the stock solution at different heights in the first box body and the second box body during the lifting process, and saves the usage amount of the analysis solution.

Description

technical field [0001] The invention relates to the technical field of xylene fractionation, in particular to an energy-saving fractionation device for xylene production. Background technique [0002] In the existing xylene fractionation device, the p-xylene in the C8 aromatics is often separated from the other three isomers by using selective adsorbents and desorbents to achieve the purpose of producing high-purity p-xylene. For the differences in the adsorption capacity of the four C8 aromatic isomers, ethylbenzene, m-xylene and o-xylene with weaker adsorption capacity are quickly desorbed from the adsorbent with the desorbent, called raffinate The p-xylene with strong adsorption capacity is selectively adsorbed by the adsorbent, and then slowly desorbed from the adsorbent with the desorbent, which is called the extraction liquid, so as to achieve the purpose of separating p-xylene. [0003] The Chinese invention patent with publication number CN111957071A in the prior ar...
