Abstract

The utility model discloses a liquid distributor in a packed tower. On the basis of the liquid distribution of the packed tower which is used at present, regular packing (3) which is used for eliminating the remaining function of fluid is arranged in a liquid collector (2). In order to make the liquid uniformly distributed in a liquid receiving major trough (5), a liquid distributing pipe (4) which is connected with the liquid collector (2) is geometrically symmetrical to the liquid receiving major trough (5). A liquid dropping pipe (6) which is arranged in the liquid receiving major trough (5) is in a thread zoom type, and the upper end of the liquid dropping pipe is provided with a V-shaped trough. The liquid passes through the liquid dropping pipe (6) to be uniformly distributed once more into a liquid receiving branch trough (7), and then is uniformly distributed for the third time above the packing by a liquid dropping hole (8) on the bottom of the liquid receiving branch trough (7) finally. The utility model has the advantages of compact design, reasonable structure and convenient installation and provides true guarantee for the display of the ascendancy of the packed tower in mass transferring engineering.

Description

Adjustable distributor

The utility model belongs to liquid distribution trough, and what relate generally to is liquid distribution trough in a kind of packed tower.

Packed tower is a kind of gas---liquid mass transfer apparatus that is widely used in fields such as oil, chemical industry, light industry, environment-friendly engineering, the application of liquid distribution trough in its packed tower, for the condition of high vacuum degree distillation, handling thermal sensitivity physics and high accuracy fractionation has vital factor.At present, liquid distribution trough in the packed tower that has come into operation, its course of work is as follows: highly pressurised liquid is entered in the liquid trap by feed tube, be dispensed to by the liquid distributing pipe that links to each other with liquid trap and be subjected to the liquid major trough, the downspout that stands to be provided with in the liquid major trough is dispensed to and is subjected to liquid to prop up groove, at last be distributed in the filler top by being subjected to liquid to prop up the liquid reducing hole that trench bottom has, because it is bigger to enter the liquid remaining kinetic energy of distributor, so liquid level shakiness in the distributor, splash phenomena is arranged, and because the liquid distributing pipe is a branch formula distribution structure with being subjected to the liquid major trough, so it is uneven objectively to cause liquid to distribute, be arranged on the downspout that is subjected in the liquid major trough because of adopting the reducing perforate, it not only designs and makes difficulty, and debugging more complicated when installing.

The purpose of this utility model promptly produces thus, and it is less to provide a kind of distributor stream pressure of flowing through to fall, and liquid distribution is even, and Installation and Debugging are convenient, occupy liquid distribution trough in the packed tower that the space is few in the tower.

For achieving the above object, the utility model is realized by following technical scheme, its existing by feed tube, liquid trap, liquid distributing pipe, be subjected to liquid major trough, downspout, propped up on the basis of the liquid distribution trough that groove forms by liquid, a structured packing that is used for the eliminate fluid remaining kinetic energy is set in liquid trap; The liquid distributing pipe that links to each other with liquid trap distributes with respect to being subjected to the liquid major trough to be how much symmetrical structures; Being arranged on the downspout that is subjected in the liquid major trough is adjustable being threaded with being subjected to the liquid major trough, and its upper end has " V " type groove.

The utility model structural design compactness is compared with liquid distribution trough in the existing packed tower, has following significant effect.

1, realizes that uniform, the cloth liquid point of liquid above filler is generally 100-1000 point/m ²

2, the overall presure drop by the liquid distribution trough air-flow general＜10Pa;

3, total height of structure can＜500mm.

4, avoided major trough and the interior liquid splash phenomenon of a groove, can make the interior liquid level of groove steady.

5, liquid level operating flexibility scope is increased.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model part-structure front view.

Accompanying drawing 3 is the vertical view of accompanying drawing 2.

Accompanying drawing 4 is adjustable downcomer structure schematic diagram.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As shown in the figure: the utility model is mainly by feed tube 1, liquid trap 2, structured packing 3, liquid distributing pipe 4, be subjected to liquid major trough 5, downspout 6, be subjected to liquid to prop up groove 7, liquid reducing hole 8 constitutes, feed tube 1 links to each other with liquid trap 2 in the packed tower with the outer pressure liquid pump of packed tower respectively, for preventing the splash phenomena of liquid in being subjected to the liquid parts, avoid liquid to rush at a part of filler, in liquid trap 2, be provided with and be used for the eliminate fluid remaining kinetic energy, make the stable gently structured packing 3 that enters liquid distributing pipe 4 of liquid, structured packing 3 is adopted and is not polluted, corrosion-resistant material is made, and it is fixed on the middle part with supporting plate in liquid trap 2; One end of liquid distributing pipe 4 links to each other with liquid trap 2, other end tip bend, and embedding is subjected in the liquid major trough 5, is subjected to liquid major trough 5 to be ellipse.The liquid distributing pipe 4 that links to each other with liquid trap 2 distributes with respect to being subjected to liquid major trough 5 to be how much symmetrical structures, purpose is to make the into first distributed uniform of tower liquid, thereby make the liquid level that is subjected in the liquid major trough 5 steady, the secondary distribution that helps liquid is even, be arranged on the downspout 6 that is subjected in the liquid major trough 5 and be thread connection with being subjected to liquid major trough 5, the top symmetry of downspout 6 has two to " V " type groove (as shown in Figure 4), it can adjust its height as required easily, thereby reaches the uniformity of control liquid secondary distribution; Be subjected to liquid to prop up groove 7 and be arranged on the lower position that is subjected to liquid major trough 5, be provided with by every mode that is subjected to liquid to prop up two downspout 6 dispense liquid of groove 7 acceptance, the liquid that are subjected in the liquid major trough 5 are evenly distributed to propped up in the groove 7 by liquid, liquid is distributed in the filler top by being subjected to liquid to prop up the liquid reducing hole 8 that groove 7 bottoms have at last.

Accumulator 2 of the present utility model, be subjected to liquid major trough 5, be subjected to liquid to prop up groove 7 to be fixedly connected with packed tower 9 respectively.
