Embodiment 2

[0038] 1. The structure and shape of the viscous damper (also known as the pipeline damper) adopting pipeline damping in the present invention are as follows: figure 2 shown. The viscous damper adopted in the present invention is a commercially available viscous damper, and the structure has no special design. The viscous damper is composed of a plunger 6, a housing 7, a damping fluid 8, a top plate 9, a bottom plate 10 and a protective cover (wrapping the whole viscous damper to prevent dust and water vapor from entering). Described plunger 6 is connected with top plate 9, and casing 7 is connected with bottom plate 10, and plunger 6 is cylindrical, and casing 7 is hollow cylindrical shape, and the diameter of plunger 6 is less than the internal diameter of casing 7, and plunger 6 is not connected with top plate 9. One end of the connection protrudes into the shell 7 and has a certain gap with the bottom plate 10 , and the damping fluid 8 is filled between the plunger 6 and...

Description

technical field [0001] The invention relates to a liquid phase adsorption separation system, which belongs to the technical field of adsorption separation. Background technique [0002] Liquid-phase adsorption separation is a process in which the adsorbent has the ability to selectively adsorb a certain component in the liquid, enriching it in the micropores of the adsorbent, and then desorbing it with an appropriate desorbent to achieve separation and purification, such as figure 1 It is based on the principle of liquid phase adsorption separation. Liquid phase adsorption separation technology is widely used in various fields of petrochemical production, such as naphtha normal isomerization separation, mixed xylene separation, mixed diethylbenzene separation, etc., to achieve the extraction, concentration and separation of target products. [0003] The main process of liquid phase adsorption separation technology is centered on the adsorption tower filled with adsorbents. ...
