At present chemical industry and fertilizer industry, there is the liquid in many towers partly or entirely to extract liquid out in the stage casing of tower.Handle than being easier to for whole extraction liquid, way commonly used now adds a cover liquid header in the middle of being exactly, and not only collects liquid but also do not hinder gas up.And extract liquid out for part, with regard to relative complex some because it is a multiduty device, at first it will play the effect of collecting liquid, its less important extraction unit is divided liquid, remaining liq also will evenly distribute again, and will also will play the effect of distribution to up gas, so the cover liquid header that is designed to that has adds a form of overlapping the slot type liquid distribution trough, this form Heavy Weight, cost height, and occupy-place height can cause increasing of tower body.

Relatively more commonly used at present is to add the form that a side line is extracted bucket out with a cover slotted disc type gas-liquid redistributor and in a side, its schematic diagram comprises slotted disc type gas-liquid redistributor as depicted in figs. 1 and 2 and extracts bucket 3 out, described slotted disc type gas-liquid redistributor by liquid barrier 1, rise air drain assembly 2, base plate is formed, rise the air drain assembly and rise the air drain unit by a plurality of rectangles and be arranged in order and form.This form has made full use of the liquid of slotted disc type gas-liquid redistributor and has collected and the function that distributes again, the design of extracting bucket out has had data to give design considerations, but by this according to the design extraction concerning the little extraction amount of little tower diameter, problem is little, bigger for tower diameter, liquid measure and all bigger tower of extraction amount, the liquid of collecting needs more the flow direction to extract bucket out, just might cause liquid flow poor this moment, liquid distribution is uneven and extract in the bucket problem such as unstabilizing liquid out, when serious even can cause the side line vaccuum phenomenon.

The utility model content

The utility model is in order to overcome weak point of the prior art, a kind of flowability that can strengthen liquid is provided, ensure liquid stabilising in all even extraction bucket of liquid distribution, cost is low, and the liquid that the large stuffing tower side line is extracted out that is applicable to that occupy-place is low is collected and the device that distributes again.

The utility model patent is achieved through the following technical solutions:

The device that a kind of liquid that is applicable to that the large stuffing tower side line is extracted out is collected and distributed, comprise slotted disc type gas-liquid redistributor and extract bucket out, described slotted disc type gas-liquid redistributor is by liquid barrier, rise the air drain assembly, base plate is formed, the described air drain assembly that rises rises the air drain unit by a plurality of rectangles and is arranged in order and forms, each rectangle rises on the air drain unit and has spray apertures, the inwall that each rectangle rises the air drain unit is provided with the drain angle steel, it is characterized in that, the described top that rises the air drain assembly is equipped with to extracting square sheet of paper used for painting or calligraphy out to the liquid barrier that tilts, the described bottom that rises the air drain assembly is equipped with the base plate of horizontal direction, and the angle of described liquid barrier and horizontal direction is 15-30 °.

Each rectangle rises the air drain unit and is divided into the individual air drain module that rises of 2-3.

The utlity model has following technique effect:

Liquid barrier is to tilt to install to extracting bucket out in the device of the present utility model, strengthened the flowability of liquid, can more flow to the liquid of collecting on the liquid barrier and extract bucket out, do not guarantee certain liquid level and drop on the liquid that directly drops on base plate on the liquid barrier by the size of controlling spout hole, and each rises the air drain unit and is divided into the individual air drain module that rises of 2-3, piecemeal rise the horizontal distribution that air drain more helps whole liquid level, so just can make full use of the collection of slotted disc type gas-liquid redistributor and distributed function again, also can look after the extraction problem of big tower diameter and big liquid measure, minimizing is because of the problem of gradient of liquid level and side line Extract quantity not sufficient on the redistributor of extracting partially liq out and causing, thereby ensures liquid stabilising in all even extraction bucket of liquid distribution.Simultaneously, keep slotted disc type gas-liquid redistributor to add and extracted the low cost that struggles against, the advantage of low occupy-place out.
