Problems solved by technology

[0003] Ordinary sieve plate extraction towers have strict requirements on operating conditions. When the flow rate of the dispersed phase is small, it is difficult to form a stable coacervate height between the plates, and the continuous phase may directly pass through the sieve holes, resulting in a decrease in mass transfer efficiency.
When the flow rate of the dispersed phase is too large, the height of the coacervate layer between the trays will be too large, resulting in the actual mass transfer interval being too small, which will also reduce the mass transfer efficiency

Abstract

The invention discloses an interlayer conical cover dispersing component and a method for dispersing liquid phase. The dispersing component comprises an outer-layer conical cover and an inner-layer conical cover which have the same center shaft; an interlayer gap is formed between the conical cover and the conical pipe; the lower end of the gap is connected by a horizontal ring-shaped bottom plateand is sealed; the vertical section of the outer-layer conical cover is shaped like an isosceles triangle or an isosceles trapezoid; multiple rows of sieve pores are formed in the side wall of the outer-layer conical cover along different height, and the outer-layer conical cover has a fan-shaped sieve plate structure when being unfolded; the upper end and the lower end of the inner-layer conicalpipe are open to form liquid flow hole channels, and the height of the inner-layer conical pipe is less than that of the outer-layer conical cover; when the vertical section of the outer-layer conical cover is shaped like the isosceles trapezoid, the outer part of outer-layer conical cover is closed by a round top plate; and at least one sieve pore is formed in the round top plate. The interlayerconical cover dispersing component has the advantages of high operation flexibility, high mass transfer efficiency, stable and reliable extraction process and the like.

Description

technical field [0001] The invention relates to a dispersing element of a sandwich conical cover and a method for dispersing a liquid phase, which is used for the effective dispersion process of the liquid phase in a multi-liquid phase flow environment, and especially provides a liquid-liquid extraction process in the field of chemical separation with a relatively large operation Elastic tray dispersion structure and efficient liquid phase dispersion method. Background technique [0002] The sieve plate column is commonly used in chemical production to complete the liquid-liquid continuous countercurrent extraction process. It has more advantages than the packed column in reducing the axial back-mixing of the continuous phase and saving costs. A reasonably designed sieve plate extraction column can achieve better separation effect . [0003] Ordinary sieve extraction towers have strict requirements on operating conditions. When the flow rate of the dispersed phase is small,...
