Abstract
The utility model relates to a high performance liquid distributor of the packed tower, comprising a main groove, a distribution groove and distribution tubes, and also a dispersion plate. The main groove is positioned on the upper part of the distribution groove. The main groove is provided with a main groove hole which is communicated with the distribution groove. The distribution tubes are positioned on the both sides of the distribution groove. The lower part of the distribution groove is provided with one row or two rows of liquid distribution holes. The liquid distribution holes are communicated with the distribution tubes. The dispersion plate is positioned on the lower end part of the distribution tubes. The dispersion plate is a corrugated plate or a plate net. The center of the upper part of the dispersion plate is provided with fins, which causes the liquid flow to disperse. The utility model has the advantages of uniform liquid distribution, small airflow resistance, liquid foam entrainment prevention, clogging prevention, high operating flexibility, etc.
Description
The utility model relates to a kind of packed tower high-performance liquid distributor, is oil refining, the widely used filler of institute distills (absorption) tower in the chemical industry vitals, belongs to oil-refining chemical and establishes gas-liquid contact mass transfer device technique field in each.
The Liquid Distribution in Packed Columns performance is to its normal running and raised the efficiency crucial influence.The present industrial liquid distribution trough that several forms are arranged: tubular type, disc type, slot type and nozzle-type.The large stuffing tower in oil refining, chemical industry, pipe distributor easily stops up, not easy to clean.Disc type is difficult for leveling, and vapour lock is bigger.The nozzle-type cost is high and easily form liquid foam entrainment.So use slot type more.
In " modern tower technology " book of publishing September nineteen ninety, disclose a kind of groove type distributor by hydrocarbon processing publishing house, its structure as shown in Figure 1.The shortcoming of this distributor is that liquid distribution point is few, and vapour lock is big, and liquid outflow port is opened at trench bottom, is easily stopped up by dirt, causes distributed mass bad.
The purpose of this utility model is a kind of packed tower high-performance distributor of design, improves the structure of existing tank type liquid distributor, to improve the liquid distribution quality, prevent that dirt from stopping up, and prevent that the drop that sprays in the aperture from by the carrying secretly of ascending air, reducing air resistance, improve operating flexibility.
The packed tower high-performance liquid distributor of the utility model design comprises major trough, distributing slot, distributor pipe and dispersion plate.Major trough is positioned at the top of distributing slot, has the major trough hole on the major trough and communicates with distributing slot.Distributor pipe is positioned at two sides of distributing slot, and the distributing slot bottom has a row or two row's liquid distributing holes, and this liquid distributing hole communicates with distributor pipe.Dispersion plate is positioned at the bottom of distributor pipe.The shape of dispersion plate can be corrugated, and is provided with fin in the central upper of dispersion plate, also can be netted, and the netted dispersion plate of each distributor pipe end fuses under every tube seat.
The packed tower high-performance liquid distributor of the utility model design has following effect:
1. liquid distribution is even: the distribution of original distributor pipe is counted improved 2～4 times.
2. because the gas channel area ratio is big, narrow groove is the point end, thereby has reduced gas-flow resistance, than the flat wide distributing slot vapour lock reduction by 20%～50% of prior art.
3. prevent the distributor liquid foam entrainment: the gas speed (than the distribution-free pipe) that distributor is carried secretly has increased by 5 times.
4. anti-the obstruction: because liquid distributing hole is positioned at the middle and lower part of distributing slot, aperture and filler all are difficult for blocked.
5. operation high resiliency: liquid distributing hole can be split into single or double, and narrow in addition groove is darker, so the operating flexibility ratio can reach 9.

Below in conjunction with accompanying drawing, introduce detailed content of the present utility model.
Among Fig. 2～Fig. 6, the 1st, major trough, the 2nd, tower wall, the 3rd, distributing slot, the 4th, distributor pipe, the 5th, corrugated dispersion plate, the 6th, packing layer, the 7th, major trough hole, the 8th, liquid distributing hole, the 9th, fin, the 10th, netted dispersion plate.
As shown in the figure, the liquid distribution trough of the utility model design comprises major trough 1, distributing slot 3 distributor pipes 4, and dispersion plate 5 is formed.Major trough 1 is positioned at the top of distributing slot 3.Having major trough hole 7 on the major trough communicates with distributing slot 3.Distributor pipe 4 is positioned at two sides of distributing slot 3, and the distributing slot bottom has a row or two row's liquid distributing holes 8, and this liquid distributing hole communicates with distributor pipe.Dispersion plate 5 is positioned at the bottom of distributor pipe 4.90 ° in the distributing slot and the major trough angle of cut.The major trough bottom has major trough hole 7 to make liquid flow to distributing slot.The every side in distributing slot bottom has horizontal liquid distributing hole 8, the distributor pipe 4 of a trapezoid cross section vertically is set on the aperture, each liquid distributing hole has a distributor pipe that it is topped, the lower end of distributor pipe is a dispersion plate 5, dispersion plate is a flat board, it can be the part of distributor pipe, also can be an assembly that is welded in the distributor pipe lower end.
Distributing slot 3 is stamped to form by a metal sheet, and width is 50～100mm (being 72mm among the embodiment), the degree of depth 150～350mm, the bottom is 60 °～90 ° of point), to reduce gas-flow resistance, have row's liquid distributing hole of φ 5～10mm near the trench bottom.Distributor pipe 4 is stamped to form by metal sheet, and cross sectional shape is trapezoidal (see figure 5).Dual-side is welded on the distributing slot, can roll over connection as wanting, and can distributor pipe be inserted at two trapezoidal semi-rings of narrow groove sidewall welding.
Liquid stream enters major trough 1 from the cat head feed pipe, and buffering flows into each distributing slot 3 through the major trough hole 7 of its bottom therein, and the liquid distributing hole 8 through groove 3 side bottoms flows into distributor pipe 4 again.Solid dregs in the liquid are deposited in the bottom of groove point 3, unlikely obstruction liquid distributing hole or filler.Liquid flows down in distributor pipe, because the protection of distributor pipe is arranged, the unlikely high velocity air that is distributed between groove blows afloat and forms entrainment to guarantee the normal running of packed tower.Liquid in the distributor pipe 4 stream is divided into several strands of thinner liquid streams, drop or becomes a banded liquid stream when the high flow by the dispersion plate of its lower end, makes the filler top better wetting, forms uniform initial distribution, thereby has improved the mass transfer effect of filler.
