Abstract

FIELD: natural gas industry; chemical industry; oil refining industry; other industries; distributing devices for liquids.

SUBSTANCE: the invention is pertaining to the distributor of liquids and may be used in natural gas industry, chemical industry, oil refining industry and other industries, in particular, in column and flushing devices for sprinkling of heads or to contact a gas stream. The device contains a distributing collector (or a box) communicating with the union of a liquid feeding and with the chutes supplied with the overflow walls with cut-outs. The external side of the overflow walls at the cut-outs is supplied with the inclined ledges crossed with the inclined ledges of the adjacent chutes. The inclined ledges are made out of a porous flexible harness and (or) the ribs arranged on the overflow walls and the porous flexible harness is made in the form of a continuous spiral fixed on the upper part of the walls in the cut-outs and in the lower part - on the ribs in a plane of the internal overflow walls. The porous harness in its lower part is supplied with a set of the flexible porous guides. The distributor ensures an effective and uniform distribution of a liquid, a decreased entrainment of a liquid by a gas stream and has a minimal height.

Description

The invention relates to distribution devices for liquids, can find application in gas, chemical, oil refining and other industries, in particular in columns and flushing apparatus for irrigation of nozzles or contact with a gas stream.

Known liquid dispenser according to copyright certificate No. 1301427, class. In 01 D 3/20, which includes a receiving pocket (open collector) connected to the fluid supply fitting and to the distribution pocket, provided with distribution pipes located under the receiving pocket.

An open pocket allows you to pre-weather the liquid before distribution, which reduces foaming, however, the disadvantage of this device is the presence of receiving and distribution pockets, transfer channels and distribution tubes that increase its height, reduce the living cross-section for gas passage and increase the gas velocity, and therefore, removal of fluid from the apparatus. In this device, the fluid is supplied above the upper level of the nozzle, which also contributes to the removal of fine droplets of liquid by the gas stream. Another disadvantage is the impossibility of horizontal installation of the distributor, which is necessary for uniform distribution of fluid at low flow rates.

Known distributor of liquid for mass transfer apparatus according to the author's certificate of the USSR No. 508260, class. In 01 D 53/18 (prototype) containing a distribution box, drain pipes with tips installed in the box, gutters equipped with movable overflow slats and leveling plate. The use of drain pipes, movable overflow slats, leveling plates improve the efficiency of liquid distribution on the surface at low flow rates, however, the disadvantages indicated in the analogue, by their considerable height, the removal of small drops of liquid by gas, remain, because the design does not allow to supply liquid directly to the contact device (nozzle).

The purpose of the invention is the expansion of functionality, increasing the efficiency of liquid distribution, i.e. distribution uniformity, reduction of fluid entrainment by a gas stream and a decrease in height.

The goal is achieved in that the fluid distributor containing the distribution manifold (or box), in communication with the fluid supply fitting and with the grooves provided with overflow walls with cutouts, is provided on the outer sides of the overflow walls at the cutouts with inclined protrusions that intersect with the inclined protrusions of adjacent grooves, which the inclined protrusions are made of a porous flexible bundle and (or) ribs located on the overflow walls, that the porous flexible bundle is made in the form of a continuous snake fixed in the upper part of the st the calf is in the cutouts, and in the lower part - on the ribs in the plane of the internal overflow walls, that harness in the lower part is equipped with many flexible, porous guides.

The authors are not known from the prior art liquid distributors in which the efficiency of liquid distribution and simplification of its design would be achieved in a similar way.

Figure 1 shows a section of the liquid distributor along the axis when the collector and the grooves are at the same level, figure 2 shows the liquid distributor in plan, figure 3 is a cross-section of the distributor when installing and fixing the grooves under the base of the collector, figure 1 and 3 also shows the location of the inclined protrusions and the fastening of the flexible porous guides to the overflow walls, in Fig. 4 - fasteners of the inclined protrusions from the porous bundle in the lower part of the walls, in Fig. 5 - pipe fittings, in Fig. 6 shows an adjustable strip fixed to from Tenke gutters.

The liquid distributor consists of a distribution manifold (box) 1 connected to a liquid supply fitting 2 by a pipe 3 and with grooves 4 pipes 5. For the possibility of dismantling the distributor through the manhole, the pipes 3, 5 are equipped with a threaded connection 6. The distribution manifold 1 from the liquid supply side in the upper part it is equipped with a cover 7, which eliminates the entrainment of liquid droplets, and on the opposite side, with a movable support 8 for horizontal installation of the collector 1. The grooves 4 are equipped with overflow walls 9 with Y-shaped cutouts 10 erhney edge. Cutouts 10 can be made on adjustable strips 11, mounted on the walls 9. Under the cutouts 10 are inclined protrusions 12, intersecting with inclined protrusions located on adjacent adjacent walls of the gutters. Inclined protrusions 12 can be made of porous bundle 13 or ribs 14 located on overflow walls 9. Inclined protrusions 12 of porous flexible bundle 13 can be made in the form of a continuous snake fixed in the upper part of the walls in the cutouts, and in the lower part, on ribs 14 and pins 15 in the plane of the internal overflow walls. The porous tow 13 at the bottom is provided with a plurality of flexible, porous guides 16.

The liquid dispenser operates as follows. The fluid is fed through the nozzle 2 and the nozzle 3 into the distribution manifold 1, from where it flows through the nozzles 5 into the gutters 4. The fluid in the gutters rises to the level of the Y-shaped cutouts 10, set to the same level, through which it is poured onto the inclined projections 12, then the liquid is wetted harnesses 13 and flows down its pores or ribs 14, distributed over many streams, through porous flexible guides 16 it goes directly to the nozzle, wall or under the liquid level. Gas rising in countercurrent to the liquid enters between the channels, is evenly distributed over the cross section of the apparatus, separating from the liquid on inclined projections (bundles, ribs).

The proposed liquid distributor performs the functions of:

- a liquid distributor and supplying it directly to the contact zone (onto the nozzle);

- gas flow distributor;

- a separation device for separating the dropping liquid from the gas stream.

The flow of liquid from the gutters onto the protrusions and its movement along the porous bundles excludes the process of crushing the liquid and disruption of it by the gas stream.

The liquid distributor has a minimum height, provides multi-point liquid distribution without the use of complex devices (vertical tubular distributors) that increase the material consumption and laboriousness of the manufacture, and provides increased gas flow through additional gas distribution and separation functions.
