Description

A kind of new packing

Technical field

The utility model relates to packed tower filler field more particularly to a kind of new packings.

Background technique

Filler is the basic building block of gas-liquid contact in packed tower, is all used extensively in many industries, with excellent acidproof Heat resistance is resistant to the corrosion of the various inorganic acids, organic acid and organic solvent in addition to hydrofluoric acid, can be in various height, low field Close and use, application range is very extensive to can be used for chemical industry, metallurgy, the drying towers of the industries such as coal gas oxygen, wastewater treatment absorb Tower scrubbing tower regenerator, the superiority and inferiority of performance be determine packed tower operating characteristics principal element.

For scrubbing tower: the removal efficiency that improve scrubbing tower will improve gas liquid interfacial area, and filler voidage is got over Height, flooding velocity is also higher, and flooding velocity directly determines that the void tower flow velocity of washing Deethanizer design, the void tower flow velocity being commonly designed are The 50% ~ 70% of flooding velocity, and void tower flow velocity determines the size of scrubbing tower diameter, so in the case that flooding velocity is high, no But design void tower flow velocity can be improved, and can reduce the diameter of scrubbing tower, reduce the occupied area of equipment.

Good filler must have following condition, and first, effective ratio area is big；Second, voidage is high；Third, Geometry is conducive to turbulent flow；And the generally existing some problems of filler currently on the market: first, structure is complicated, not easy cleaning, just If at high cost；Second, occur intussusception phenomenon between filler and filler, influence packing layer pressure drop, and is or even causes short stream existing As；Third, filler self-strength is inadequate, and underfilling usually can compressive strain.

Utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of scientific structure design, Effective ratio area is big, voidage is big, high mechanical strength, is not easy to plug, convenient for a kind of new packing of cleaning.

To realize the utility model the following technical schemes are provided: a kind of new packing, the filler are column regular polygon Or it is cylindrical, the filler is divided into the upper, middle and lower, and the upper, middle and lower are waffle slab, the waffle slab Grid intersection be equipped with protrusion, it is described protrusion be needle-shaped or droplet-like, protrusion be it is hollow；The protrusion of the middle layer waffle slab is Two-way, vertically downward, vertically upward, the waffle slab is convex for the protrusion of lower layer's waffle slab for the protrusion of the upper layer waffle slab Playing number is 30 ~ 50.

Preferably, the height of the protrusion is inconsistent, between highest height of projection is less than between waffle slab and waffle slab Every 1/2.

Preferably, the filler is column regular hexagon, regular heptagon or octagon, most preferably positive eight side of column Shape.

Preferably, the filler is plastics.

The usefulness of the utility model: it will form when spray liquid is sprayed onto the acicular texture on filler ten hundreds of Droplet adds up the bottom surface area of a large amount of droplets, improves more effective mass transfer areas for gas-liquid contact, greatly improves Matter transfer efficiency, acicular texture can allow by air-flow it is more uniform, gas-liquid contact more sufficiently improves matter transfer efficiency, uniformly The smooth no dead angle in the acicular texture surface of distribution makes crystal class and algae be not easy to adhere to less scaling easy cleaning, and voidage is big, most High up to 96.3%, flooding velocity is high, and when design can reduce tower diameter, so that pressure is reduced to 1/2 to the 1/3 of other fillers, Lower pressure drop allows to select the blower of smaller power, and fan operation expense can reduce by 50% or so, considerably reduce equipment Operating cost, filled using scattered heap form, spray liquid can all be dispersed into smaller droplet when passing through each layer of filler, can exist Secondary-atomizing phenomenon, high mechanical strength are formed in packing layer, long service life not enough will not be such that bottom filling becomes because of intensity Shape, column construction will not intussusception, can to avoid packing layer settle the short flow problem of bring.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Fig. 2 is the utility model front view.

Fig. 3 is 2 front view of embodiment.

Fig. 4 is 3 structural schematic diagram of embodiment.

In figure: 1 be waffle slab, 2 be protrusion.

Specific embodiment

Embodiment 1(refers to Fig. 1 and Fig. 2): a kind of new packing, the filler are column regular polygon, the filler point For the upper, middle and lower, the upper, middle and lower are waffle slab 1, and the grid intersection of the waffle slab 1 is equipped with For protrusion 2, described raised 2 to be needle-shaped, protrusion 2 is hollow；The protrusion 2 of the middle layer waffle slab 1 is two-way, the upper layer waffle slab Vertically downward, vertically upward, 2 numbers of protrusion are 30 ~ 50 to the protrusion 2 of lower layer's waffle slab 1 to 1 protrusion 2 on the waffle slab 1 A, raised 2 height is inconsistent, and highest raised 2 height is less than 1/2 be spaced between waffle slab 1 and waffle slab 1, institute Stating filler is column regular hexagon, regular heptagon or octagon, most preferably column octagon, and the filler is plastics.

Embodiment 2(refers to Fig. 3): the protrusion 2 of 1 grid intersection of waffle slab is droplet-like.

Embodiment 3(refers to Fig. 4): filler is cylinder, and protrusion 2 is needle-shaped or droplet-like.

This filler working principle: the present apparatus uses dropping point technology, when spray liquid is sprayed onto acicular texture or liquid on filler It will form ten hundreds of droplets when dripping structure, add up the bottom surface area of a large amount of droplets, improved more for gas-liquid contact Effective mass transfer area, substantially increase matter transfer efficiency, acicular texture can allow by air-flow it is more uniform, gas-liquid contact is more Add sufficiently improve matter transfer efficiency, the equally distributed smooth no dead angle in acicular texture surface make crystal class and algae be not easy adherency be not easy Fouling easy cleaning, voidage is big, reaches as high as 96.3%, and flooding velocity is high, and when design can reduce tower diameter, thus pressure drop It is 1/2 to the 1/3 of other fillers, lower pressure drop allows to select the blower of smaller power, and fan operation expense can reduce by 50% Left and right, considerably reduces the operating cost of equipment, is filled using scattered heap form, and spray liquid can all divide when passing through each layer of filler Smaller droplet is dissipated into, secondary-atomizing phenomenon, high mechanical strength, long service life, single layer installation can be formed in packing layer Height not enough will not be such that bottom filling deforms up to 9 meters because of intensity, column construction will not intussusception, can be to avoid packing layer Settle the short flow problem of bring.

The utility model is not limited to a kind of new packing involved in above-mentioned specific embodiment, is familiar with this technology neck The personnel in domain can also make a variety of variations accordingly, but it is any be equal with the utility model or similar variation should all cover this In the range of utility model claims.
