Description

Trough-tray type liquid distributor

Technical Field

The utility model relates to a liquid distributor, especially a fluted disc formula liquid distributor.

Background

In the mass transfer equipment used in the industrial production of oil refining, petrochemical industry and the like, a packed tower belongs to important mass transfer and heat transfer separation equipment. In the packed tower, the liquid distributor is an important internal part, and the liquid entering the packed bed layer is uniformly distributed on the packed bed layer, passes through the packed bed layer under the action of gravity and is uniformly contacted with ascending gas, so that the phenomenon of poor distribution such as channeling, wall flow and the like is avoided, the opportunity of two-phase contact is improved, the separation efficiency of the packed tower is exerted, and the stable operation of the packed tower is ensured. Meanwhile, the liquid distributor also plays a role in distributing gas. The trough-tray type liquid distributor has the functions of receiving liquid from the outside of the fractionating tower, collecting liquid from the inside of the packed tower at the upper part of the packed bed layer and distributing ascending gas in the packed bed layer to a certain extent, so that the trough-tray type liquid distributor is widely applied to the packed fractionating tower.

As shown in fig. 1, the trough-tray type liquid distributor which is widely used at present mainly has a distribution pipe type. The main disadvantage of the trough-tray distributor is point distribution, which is easy to overflow when the liquid is too much due to too few distribution points, thus affecting the liquid distribution effect.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a trough plate formula liquid distributor can improve liquid evenly distributed effect.

In order to solve the technical problem, the utility model adopts the technical scheme that: the utility model provides a fluted disc formula liquid distributor which characterized in that: including liquid level groove and frid, be provided with a plurality of distribution grooves on the frid, the distribution groove is an upper end open-ended hollow tubular structure, and the bottom surface of distribution groove flushes with the bottom surface of frid mutually, and outside the frid was stretched out to the top surface of distribution groove, still seted up a plurality of distribution holes on the one section cell wall that the distribution groove stretches out the frid, still seted up a plurality of distribution pipes around lieing in each distribution groove in the frid, the top at the distribution groove is fixed to the liquid level groove, top-down has opened several groups overflow hole group on the cell wall of liquid level groove, and every group overflow hole group comprises a plurality of overflow holes along the outer wall horizontal distribution of liquid level groove jointly, has seted up a plurality of V-arrangement overflow launders along the last border horizontal distribution of liquid level groove at the cell wall top of liquid level groove, and the area of overflow launder is greater than the area of overflow hole.

Further, the radial length of the liquid level groove is not less than the axial length formed by connecting all the distribution grooves.

Furthermore, the liquid level groove and the distribution groove are both of an inner groove structure.

The utility model has the advantages that:

liquid gets into liquid level tank inslot, the radial axial that covers all distribution grooves in liquid level tank, liquid spills over the distribution groove from the overflow hole when liquid level height in the liquid level tank reaches the overflow hole in, liquid spills over the distribution pipe from the distribution hole when the water level reaches distribution hole place height in the distribution groove, thereby reach the average distribution of liquid, overflow hole can't in time get rid of liquid when liquid level inslot water yield is too much, can spill over the distribution through the V-arrangement overflow launder at liquid level tank top this moment, prevent to divide the liquid uneven, the even effect of distribution of liquid has been improved.

For the liquid level tank, the mode that the overflow holes are matched with the V-shaped overflow grooves is adopted, when the liquid flow is small, the purpose of uniformly distributing liquid is directly realized through the overflow holes, and when the liquid flow is large, the purpose of rapidly and uniformly distributing a large amount of liquid is realized through the matching of the overflow holes and the overflow grooves, so that the liquid uniformly distributing efficiency is improved.

Detailed Description

The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.

A trough-tray liquid distributor as shown in fig. 2, characterized by: comprises a liquid level tank 1 and a tank tray 2.

Be provided with a plurality of distribution groove 4 that distribute side by side on frid 2, distribution groove 4 is upper end open-ended hollow tubular structure, and the bottom surface of distribution groove 4 flushes mutually with frid 2's bottom surface, the top surface of distribution groove 4 stretches out from frid 2's top, several distribution hole 5 has still been seted up on distribution groove 4 is located one section cell wall 3 that stretches out frid 2, be located still being provided with a plurality of distribution pipes 6 around each distribution groove 4 in frid 2, and the liquid in the distribution groove 4 flows into in the distribution pipe 6 through distribution hole 5.

The liquid level tank 1 is fixed on the top end of the distribution tank 4, a plurality of groups of overflow hole groups are arranged on the tank wall of the liquid level tank 1, each group of overflow hole groups is composed of a plurality of overflow holes 7 which are horizontally distributed along the outer wall of the liquid level tank 1, a plurality of V-shaped overflow grooves 8 which are horizontally distributed along the upper edge of the liquid level tank 1 are arranged at the top of the liquid level tank 1, the area of each overflow groove 8 is larger than that of each overflow hole 7, and liquid in the liquid level tank 1 flows into each distribution tank 4 through the overflow holes 7 or the overflow grooves 8. For the liquid level tank 1, adopt overflow hole 7 and the mode of V-arrangement overflow launder 8 complex, when liquid flow is little, directly realize the purpose of liquid equipartition through overflow hole 7, and when liquid flow is big, then through the cooperation of overflow hole 7 with overflow launder 8, liquid flows out jointly, realizes the purpose of the quick equipartition of a large amount of liquid, improves the efficiency of liquid equipartition.

The radial length of the liquid level groove 1 is not less than the axial length of all the distribution grooves 4. The design is to ensure that the liquid in the liquid level tank 1 can flow to all the distribution tanks 4, and avoid the phenomenon that the partial distribution tanks 4 cannot receive the liquid.

The liquid level tank 1 and the distribution tank 4 are both of an inner tank structure.

The working principle is as follows: liquid gets into liquid level groove 1 in, liquid level groove 1 radially covers all axial of distributing groove 4, when liquid level height reaches to be located the overflow hole 7 of bottommost in liquid level groove 1, liquid overflows and flows to in the distributing groove 4 from each overflow hole 7 of this position, and when the water level reaches to be located the height of distributing hole 5 place of bottommost in distributing groove 4, liquid can overflow from distributing hole 5 and flow to in distributing pipe 6, thereby reach the average distribution of liquid, overflow hole can't in time get rid of liquid when liquid level inslot 1 internal water volume is too much, can overflow the distribution through the V-arrangement overflow launder 8 at liquid level groove top this moment, prevent to divide the liquid inequality, the even effect of distribution of liquid has been improved.
