Problems solved by technology

[0006] However, the distribution of light and heavy phases in special liquid-liquid packed towers is relatively difficult, and there are few studies on this. At present, the light and heavy phases are redistributed mainly through structured packing. This distribution only relies on the simple guiding effect of structured packing. Lack of theoretical basis, and can not be redistributed well on the entire tower section, not only the uniform distribution effect is poor, but also the cost is high

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , 2 As shown, a light and heavy phase redistribution device of a liquid-liquid extraction packed tower includes a liquid distribution plate 1, a distribution pipe 2, a distribution pipe cap 3, a distribution pipe cap supporting rib 4, and a blind plate 5 at the upper end of the distribution pipe cap. The liquid distribution plate 1 is circular, and the upper part is evenly distributed with the distribution pipe installation holes 6 for the light phase and the heavy phase distribution holes 7 for the heavy phase, wherein, according to the specific equipment requirements, the distribution pipe installation holes 6 and the heavy phase distribution The unit drop point density per square meter of the hole 7 is appropriately selected within 10-200, and the aperture is appropriately selected within 30-200 mm. Preferably, the unit drop point density pe...

Abstract

The invention provides a light and heavy phase redistribution device for a liquid-liquid extraction packed tower. The device comprises a liquid distribution plate, distribution pipes, distribution pipe caps, distribution pipe cap support rib plates and blind plates at the upper ends of the distribution pipe caps, wherein the liquid distribution plate is circular; distribution pipe mounting holes only for the passage of a light phase and heavy phase distribution holes only for the passage of a heavy phase are uniformly distributed in the upper part of the liquid distribution plate; the distribution pipes are welded on the distribution pipe mounting holes; the distribution pipe caps are circular pipes of which the two ends are open, and are fixedly arranged on the distribution pipes in a sleeving manner through the distribution pipe cap support rib plates; the top ends of the distribution pipe caps are protruded from the top ends of the distribution pipes, the bottom ends of the distribution pipe caps and the liquid distribution plate are arranged at intervals, and the inner walls of the distribution pipe caps and the outer walls of the distribution pipes are arranged at intervals; the blind plates at the upper ends of the distribution pipe caps are fixedly welded at the top ends of the distribution pipe caps. The light and heavy phase redistribution device for the liquid-liquid extraction packed tower is arranged in the liquid-liquid extraction packed tower, an upper-section packing of the liquid-liquid extraction packed tower is a random packing, a lower-section packing of the liquid-liquid extraction packed tower is a structured packing or a random packing, and the light and heavy phase redistribution device is arranged in the upper-section random packing.

Description

technical field [0001] The invention relates to a light and heavy phase redistribution device in a liquid-liquid extraction packed tower. Background technique [0002] The function of the liquid redistribution device in the ordinary gas-liquid packed tower is to prevent the efficiency of the tower from being too high, so it is necessary to install a liquid redistributor to improve the effective surface of mass transfer and heat transfer, improve the contact between phases, and improve the efficiency of the tower. efficiency. [0003] The flow of liquid in the packing layer in the packed tower is not a uniform plug flow, but channel flow, bias flow, and wall flow, which will cause the amplification effect and end effect of the packed tower. The purpose of rational design and selection of the liquid redistributor is Reduce and prevent the amplification effect of the packed tower, thereby reducing the height and diameter of the tower, and reducing the cost or operating cost. ...
