Abstract
The utility model relates to a device of a flow adjustable separation plate collection and redistribution device. A separation plate is placed in the middle of a placing tower and the flow of liquid on one side is flexibly adjusted by a flow controller outside the tower; collection channels on the two sides are connected by a liquid-phase balance pipe so as to guarantee that the compositions of the liquid on the two sides of the separation plate and the heights of liquid levels of the channels are the same and the liquid on the two sides flows down at the same flow speed; an inclined angle is formed between each liquid guide pipe which is led out of the tower and the horizontal plane, and the liquid guide pipes and the horizontal plane are in smooth transition so as to reduce the liquid flowing resistance; the flowing of the liquid takes the height of the liquid level on the disc as a driving force; collection boxes on the two sides are fixed on the tower wall and uniformly-distributed small holes are formed in the bottom so as to have a liquid buffering effect, uniformly distribute the liquid, prevent from impacts of large-liquid-amount fluid to the liquid level of the liquid collection and redistribution device, and guarantee the operation stability of the device. The utility model provides a simple and stable method for adjusting a flow distribution ratio of the liquid on the two sides of the separation plate in a distillation tower. Static equipment is used so that extra energies including electricity, high-pressure steam and the like do not need to be consumed.
Description
Technical field
The utility model relates to a kind of dividing wall column liquid distribution trough, and the partition plate liquid that particularly relates to a kind of adjustable-flow is collected apparatus for redistributing.
Background technology
Rectifying is the industrial liquid mixture lock out operation that is widely used in most, rectifying why can separating mixture, key is the application that refluxes, but necessary lot of energy refluxes, except selecting the reflux ratio of economical rationality, developed some energy-saving rectifying columns both at home and abroad, improve the thermodynamic efficiency of rectifying column, reduce energy consumption, such as heat pump distillation, differential pressure heat coupling rectification, dividing plate rectifying etc.
Yet less for the research of dividing wall column both at home and abroad, dividing plate rectifying is, in rectifying column inside, one vertical partition plate is set, rectifying feed zone and middle extraction section four parts that rectifying column is divided into to public rectifying section, public stripping section, is separated by dividing plate.Because dividing wall column can reduce the material back mixing, than traditional cascade towers flow process is energy-conservation, reach as high as 60%, and can save 30% equipment investment, the most obvious to separating 3 component system power savings advantages.
The phase assignment of traffic of dividing wall column median septum both sides is key technologies of dividing plate rectifying.In dividing plate one side, be provided with charging aperture, opposite side is provided with discharging opening, the vapour phase flow of controlling the dividing plate both sides mainly completes by the pressure drop of both sides.Both sides vapour phase flow is uniformly distributed, need makes the pressure drop of dividing plate both sides consistent.If dividing plate one side liquid phase load is greater than opposite side, gas will flow into the little side of liquid phase load in a large number, and it is inhomogeneous that this will cause the vapour phase of both sides to be unworthy of, and can not carry out normal activity.Because charging aperture and discharging opening are located at the dividing plate both sides, therefore, consistent in order to guarantee both sides liquid phase load, the liquid that gets off from public rectifying section flow into the flow of feed side need be less than the flow of exit side.
Make dividing plate both sides liquid phase flow unequal, two kinds of methods are generally arranged: 1, dividing plate is not placed in the middle of tower; 2, flow distributor of design is controlled fluid flow above dividing plate.Adopt first method, can only be for fixing separation operating mode, if operating condition changes, the expense of follow-up transformation partitioned column is large, complicated operation.Adopt second method to have obvious advantage, can regulate flexibly dividing plate both sides liquid phase distribution ratio of liquid flow according to actual condition.
CN102872609 discloses and a kind ofly can regulate the liquid backflow distribution ratio of dividing plate both sides and the method for gas distribution ratio, this method comprises a liquid backflow system: dividing plate upper end liquid is all extracted out, again it is back to respectively to the dividing plate both sides in proportion, can cause extracting out like this temperature change of liquid, and then can affect separating effect, and need stage casing backflow surge tank and stage casing reflux pump are installed, invest more; This patent has also been announced a gas distributor: adopts moving equipment, and it is arranged on to rectifying column inside, and complex structure, wayward, on engineering, vapour phase is distributed to more difficult realization.
In the US5755933 patent, point out, by dividing plate being extended to bottom or the top of dividing wall column, by reboiler and condenser, carry out the distribution ratio of adjustments of gas and liquid.But the improved rectifying column of this method has not been traditional dividing wall column.
In the US7267746 patent, point out, by detecting respectively the temperature of uprising gas at the bottom of overhead reflux liquid and tower, come dynamic adjustments to enter the distribution ratio of dividing plate both sides liquid.This method complicated operation, equipment is more, is applicable to produce alkylated aromatic hydrocarbon.
Summary of the invention
The purpose of this utility model is to provide a kind of device of adjustable partition plate liquid distributor, liquid phase flow-rate ratio that can flexible modulation dividing plate both sides.The static equipment device that uses the utility model to provide, the position without changing dividing plate, can facilitate, the fluid flow distribution ratio on stable adjusting dividing plate both sides.
