Description

Fluted disc formula liquid distributor with remove foam function

Technical Field

The utility model relates to a chemical tower internals makes technical field, in particular to a fluted disc formula liquid distributor that is used for having of packed tower to remove foam function.

Background

In order to reduce the amplification effect caused by the liquid maldistribution and fully exert the packing efficiency, a liquid distributor is required to be installed in a packed tower, and the liquid is uniformly distributed on the top of a packing layer, the quality of the initial distribution of the liquid not only influences the mass transfer efficiency of the packing, but also influences the operation flexibility of the packing, therefore, the liquid distributor is an extremely key internal part in the packed tower and can avoid the occurrence of maldistribution phenomena such as channeling, wall flow and the like, the types of the existing liquid distributors are more, the selection is mainly based on the distribution quality, the operation flexibility, the treatment capacity, the gas resistance, the levelness and the like, the phenomenon that the liquid is easy to splash everywhere when the outlet flow of the existing liquid distributor flows to the packing in a lower tower is easily generated, the uniformity of the liquid distribution is greatly influenced, in addition, when the operation gas velocity in the tower is larger or the entrainment phenomenon of the liquid is serious, the liquid distributor is required to be additionally provided with a demister above the liquid distributor, the main purpose is to remove liquid drops in air flow from a filler to an outlet, the gas is provided with a large amount of liquid foam and fog drops when leaving the filler tower at the top of the tower, the gas-liquid mass transfer efficiency is reduced, the demister is often required to be arranged at the top of the tower for recycling the liquid phase, the demister is generally formed by defoaming wire meshes with different diameters and the like, the structure not only increases the height of the tower, but also has a less ideal defoaming effect.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the not enough of existence among the above-mentioned prior art liquid distributor, provide a rational in infrastructure, distribute evenly, stability can be good, the effectual fluted disc formula liquid distributor that has the defoaming function of defogging foam.

The utility model provides an above-mentioned technical problem's technical scheme as follows: the utility model provides a trough tray formula liquid distributor with remove foam function, it includes chassis, liquid distribution groove, rises the gas groove, it sets up and runs through in the chassis to rise the gas groove symmetry, it forms the liquid distribution groove to rise between the gas groove, rises the gas groove upper end and is provided with the collecting plate, rises the inboard symmetric interval of gas groove and is provided with the catheter, rises the gas groove in the lower part outside symmetry be provided with the communicating overflow hole of catheter, the symmetry is provided with right angle triangle ripples gusset on the catheter, crisscross on the crest of the right angle triangle ripples gusset of both sides is provided with arc fender foam strip, rises gas groove lower extreme symmetry and is provided with the drain buffer board corresponding with catheter lower part exit position, be provided with the buffering step that the width widens in proper order from top to bottom on the drain buffer board.

Further, the cross section of the liquid collecting plate is V-shaped.

The utility model has the advantages that: compared with the prior art, 1, the plurality of right-angle triangular wave rib plates positioned in the gas lift pipe and the arc-shaped foam blocking strips arranged on the wave crests in a staggered mode are arranged, so that when the gas-liquid phase passes through the right-angle positions and the arc-shaped foam blocking strips, spray foam and liquid drops in the gas can be blocked, the tower height is reduced, and the mass transfer efficiency of the gas and the liquid is improved; 2. by arranging the liquid guide buffer plate at the outlet of the liquid guide pipe, the phenomenon that liquid at the outlet of the liquid guide pipe is easy to splash everywhere is avoided, and the liquid is distributed more uniformly.

In the figure, the device comprises a base plate 1, a base plate 2, a liquid collecting plate 3, a liquid distribution groove 4, an air lifting groove 5, a liquid guide pipe 6, a right-angle triangular wave rib plate 7, an arc-shaped foam blocking strip 8, an overflow hole 9, a liquid guide buffer plate 10, a support frame 11 and a buffer step.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in the figure, the trough tray type liquid distributor with the defoaming function comprises a chassis 1, liquid distribution grooves 3 and air lifting grooves 4, wherein the air lifting grooves are symmetrically arranged and penetrate through the chassis, the liquid distribution grooves are formed between the air lifting grooves, the upper ends of the air lifting grooves are provided with liquid collecting plates 2, the liquid collecting plates are supported by support frames 10 fixed on the air lifting grooves, the cross sections of the liquid collecting plates are V-shaped, the two sides of each liquid collecting plate slightly extend out of the support frames, liquid guide pipes 5 are symmetrically arranged on the inner sides of the air lifting grooves at intervals, overflow holes 8 communicated with the liquid guide pipes are symmetrically arranged on the outer sides of the middle lower parts of the air lifting grooves, the cross sections of the liquid guide pipes are triangular, right-angle triangular wave rib plates 6 are symmetrically arranged on the liquid guide pipes, arc-shaped foam blocking strips 7 are staggered on the wave crests of the right-angle triangular wave rib plates, and the liquid guide buffer plate is provided with buffer steps 11 with widths gradually widened from top to bottom.

When the packing tower works, liquid in a liquid inlet pipe (not shown in the figure) of the packing tower falls into the liquid collecting plate 2 and then is collected together, then the liquid respectively flows into the liquid distribution grooves 3 between the air lifting grooves 4, the liquid in the liquid distribution grooves gradually rises and then flows into the liquid guide pipe 5 through the overflow holes 8, the liquid is uniformly distributed in the liquid guide pipe from top to bottom and flows onto the liquid guide buffer plate 9 at the outlet, the liquid is buffered by the plurality of buffer steps 11 and then is slowly and uniformly distributed in the packing to be contacted with gas phase from bottom to top for mass transfer, the gas phase with the mist and the liquid drops enters the air lifting grooves 4 of the liquid distributor after passing through the packing layer, the mist and the liquid drops are removed at the right angle of the right-angle triangular wave rib plate 6 and the arc-shaped foam blocking strips 7, and finally the gas drops are intermittently dispersed at the two sides of the support frame 10 between the liquid collecting plate and.
