Abstract

The utility model relates to an integrated capillary gas liquid distributor applied to a packed tower, which comprises a shower channel and an air flow channel. The utility model is characterized in that the utility model is composed of a distribution disc, ventilated grooves, capillaries and capillary integrated pipes, wherein the distribution disc is a circular disc with a certain height; the air flow channel adopts the way that the distribution disc is provided with ventilated grooves which are uniformly distributed; the peripheries of the ventilated grooves are provided with the capillary integrated pipes of the shower channel, which are uniformly distributed and have equal sizes; capillary bundles with identical specifications are arranged in the integrated pipes. If applied, the utility model can realize liquid collection, homogeneous distribution and homogeneous air rising, and the utility model is a major component in the tower with a high-efficient packed and separation efficiency. The integrated capillary gas liquid distributor is especially suitable for packed towers which have strict requirements to liquid distribution, such as a high-efficient and multiple-pipe tower, helical packed towers connected in parallel, etc.

Description

Integrated-type capillary gas-liquid allotter

One, technical field:

The utility model relates to a kind of gas-liquid allotter of packed tower, particularly discloses a kind of integrated-type capillary gas-liquid allotter, and it belongs to the internals device of knockout tower of mass transfer in chemical industry, the medicine and other fields.

Two, background technology:

Packed tower is present widely used mass transfer apparatus, has the advantage that flux is big, efficient is high, pressure drop is little.Various efficient structured packings and random packing be owing to have big surface area and bulk density, thereby have good mass transfer effect, but the bad initial distribution of liquid can cause mass-transfer efficiency sharply to descend.There is not good gas-liquid allotter, packed tower even can not normal running, the superiority of new type high-efficient packing is difficult to performance.Good gas-liquid allotter requires have enough pouring to fall dot density, drenches to fall a little to be evenly distributed, and flow is even, suitable operating flexibility and enough gas channels.

Three, summary of the invention:

The purpose of this utility model is the defective that overcomes prior art, a kind of integrated-type capillary gas-liquid allotter is disclosed, this distributor has uniformly, the pouring of big density is fallen a little, can guarantee simultaneously the even distribution of gas again, be the tower internals of guaranteeing the high efficiency packing mass-transfer performance, be specially adapted to efficient multiple-tube column, helical packing tower in parallel etc. and liquid distributed the packed tower of being strict with.

The utility model is achieved in that a kind of integrated-type capillary gas-liquid allotter, comprise drenching and fall passage and gas channel, it is characterized in that: it is made of distribution plate, ventilating groove, capillary, the integrated pipe of capillary, and distribution plate is the disk that height is arranged, and diameter is slightly less than the internal diameter of tower pipe; Trying to get to the heart of a matter offers equally distributed ventilating groove, promptly described gas channel, and groove is high to equate that with dish is high the ventilative gross area accounts for 30～40% of distribution plate floor space; Offer equally distributed, equal-sized pouring around the ventilating groove and fall the integrated pipe of passage capillary, integrated pipe upper end is equal with the distribution plate bottom surface, pipe range 20～30mm, internal diameter 10～20mm; Be covered with diameter, bundle of capillary tubes that length is identical in the integrated pipe; Bundle of capillary tubes upper end is integrated in the integrated pipe of capillary, and the lower end layout of evenly scattering becomes to drench the disc of the scope of falling, and drenches to fall diameter and equal the filler diameter.

The beneficial effects of the utility model are: the pouring with uniform, big density is fallen a little, can realize the collection of liquid, evenly distribute and evenly rise gas, guarantee the high efficiency packing separative efficiency, guarantee the high efficiency packing mass-transfer performance, be specially adapted to efficient multiple-tube column, helical packing tower in parallel etc. and liquid distributed the packed tower of being strict with.

Four, description of drawings:

Accompanying drawing 1 is the utility model structural representation

Accompanying drawing 2 is the utility model vertical views.

Among the figure: 1, the integrated pipe of capillary; 2, distribution plate; 3, ventilating groove; 4, capillary.

Five, the specific embodiment:

With reference to the accompanying drawings, the utility model is by distribution plate 2, ventilating groove 3, capillary 4, capillary integrated-type capillary gas-liquid allotter that integrated pipe 1 constitutes, and it is characterized in that: distribution plate 2 is for there being the disk of height, and diameter is slightly less than the internal diameter of tower pipe; Described gas channel is to try to get to the heart of a matter to offer equally distributed ventilating groove 3, and groove is high to equate that with dish is high the ventilative gross area accounts for 30～40% of distribution plate floor space; Offer equally distributed, equal-sized pouring around the ventilating groove 3 and fall the integrated pipe 1 of passage capillary, integrated pipe upper end is equal with the distribution plate bottom surface, pipe range 20～30mm, internal diameter 10～20mm; Be covered with diameter, bundle of capillary tubes that length is identical in the integrated pipe; Bundle of capillary tubes upper end is integrated, and the lower end layout of evenly scattering becomes to drench the disc of the scope of falling, and drenches to fall diameter and equal the filler diameter.

Distribution plate 2 plays the effect of collecting liquid, and can bring into play the elasticity of distributor; The liquid of collecting equably, big density drenches by integrated pipe 1 of capillary and capillary 4 and drops on the high efficiency packing; The gas that rises rises to the epimere packing layer by distribution plate with space between the tower pipe and the ventilating groove in the distributor 3, thereby realizes the equally distributed purpose of gas-liquid.

The utility model can be widely used in the mass transfer separation process in chemical industry, the medicine and other fields, pouring with uniform, big density is fallen a little, can realize the collection of liquid, evenly distribute and evenly rise gas, guarantee the high efficiency packing separative efficiency, guarantee the high efficiency packing mass-transfer performance.
