Abstract

The utility model relates to a flat ring for filling, which belongs to the technical field of a filled tower of chemical equipment, in particular to the designing technology of filling member of the filled tower. The flat ring for filling is characterized in that the ring is a flat shape; three rectangular circular arc holes are uniformly arranged on the peripheral wall of the flat type ring; a raised edge is separated between two adjacent rectangular circular arc holes, circular arc-shaped ribs protruding to the centre of a circle are connected between two raised edges, and the flat ring is separated into four parts by the three circular arc-shaped ribs; the middle parts of the circular arc-shaped ribs are provided with rectangular circular arc-shaped small holes; and rectangular pieces which form 90 degrees with the hole edges are arranged on each of the two hole edges of the rectangular circular arc-shaped small holes of the circular arc-shaped ribs. When being implemented, the utility model has the advantages of enhancing mass transfer performance of the filling, greatly improving flux and mass transfer efficiency, reducing filling cost and being propitious to develop super-flat ring of SRP series provided at present.

Description

A kind of flat ring as filler

Technical field

Belong to packed tower design field in the chemical industry equipment, exactly relate to the designing technique of filler member in the packed tower.

Background technology

Industrial, because the structure of filler and performance have decisive influence to the technical-economic index of packed tower, it is a kind of product that has a large capacity and a wide range, have great economic implications and social benefit, simple in structure because of it again, easy to operate, also therefore obtained using widely as core component-filler, thereby each state has all carried out deep research to the structure and the performance of filler, formulated out miscellaneous chemical filler, generally can be divided into dumped packing and structured packing two classes, dumped packing is applicable to atmospheric tower and pressurized operation, and structured packing is applicable to decompression operation.Structured packing is with its mass-transfer efficiency height, and resistance drop is little and obtain people's favor, involves great expense but there is also, and cost of manufacture is higher; The shortcoming that maintenance, filling and dismounting are difficult for.And dumped packing is on the contrary, and is cheap, overhauls, loads and unloads easily, so application is comparatively extensive, and ring height and the less ring packing of aspect ratio have more characteristic as cascade ring and oblate-ring filler in arc web bent inward.Because the ratio of height to diameter of cascade ring filler only is the Bao earrings half, center of gravity is lower, increased and thrown in the systematicness that arrange the back at random in tower, and utilized inner surface more fully, so the resistance drop when helping reducing continuous phase and improve mass-transfer efficiency by packing layer.But the ratio of height to diameter of this filler is still bigger, and the inner tongue structure is also undesirable, and also there is much room for improvement, and its rigid structure requires depth of packing bigger, consumes more steel.Curved arched ribs chip architecture in this filler has adopted, time limit makes the filler inner passage more reasonable, has also increased the intensity of filler, has eliminated the flange that may cause drop clustering knot or material coking; This filler adopts extremely low ratio of height to diameter, makes filler also can embody largely arrangement in order when huddling, thereby has reduced the resistance drop of filler, has suppressed the imperfect of two-phase effectively and has flowed, and has further improved the disposal ability and the mass-transfer efficiency of filler; This filler is convenient to processing, can make to adapt to various production requirements of multiple material.But this filler yet leaves some room for improvement, and as loop configuration, packing specific area is limited, though curved arc rib is being divided into four parts, still having the leeway of further cutting apart in three in the filler, in addition, the rigid structure of filler also needs thicker sheet material, and consumptive material is more.

Summary of the invention

The utility model provides a kind of and further improve packing specific area and mass-transfer efficiency on the basis of interior curved arc sheet filler, and reduces the consumption of filler material, and is cheap, overhauls, loads and unloads easily, a kind of flat ring as filler that mass-transfer efficiency is high.

The technical solution of the utility model:

A kind of flat ring as filler comprises ring, and its scheme is: encircle to flat-shaped; At the perisporium of flat-shaped ring, evenly offer three rectangle circular holes; There is a grade limit to be separated by between the two adjacent rectangle circular holes, between two grades of limits, connects the circular-arc muscle sheet that protrudes to the circle center, form and flat ring is separated into four parts by three circular-arc muscle sheets; Circular-arc muscle sheet middle part has the circular-arc aperture of rectangle; On the limit, two holes of the circular-arc aperture of rectangle of circular-arc muscle sheet, the right angle sheets that constitute 90 degree with the limit, hole are arranged respectively.

Good effect behind enforcement the utility model is:

1, because muscle sheet tooth type structures has increased the some contact between filler jointly, the voidage of filler is increased, liquid converges with spaced point and increases, make that the filler flux increases, pressure drop reduces, also help liquid and upgrade, help improving the mass-transfer performance of filler at the distribution and the promotion liquid surface of filling surface.

2, the end face coefficient of this filler is big, adopts thin metallic plate to roll usually, by curved arc shape square saddle type circle in striking out filler has been play a part to strengthen not only having reduced the accumulation severe of filler, and has reduced the filler cost.

3, the inner particular structure of the ring flat ring of saddle arc, when the two-phase fluid adverse current was passed through filler, camber muscle sheet and tongue piece can effectively promote drop group's dispersion, a polymerization disperses circulation again and again, has further accelerated the renewal on liquid film surface.This internal structure also can be cut continuous phase liquid better, suppresses imperfect and flows.Therefore when diameter was identical, therefore when diameter was identical, the unit volume of filler was higher than the external packing ring of introducing such as cascade ring, Pall ring with the ratio of surface area, the super flat ring of SRP series that also be convenient to fully, development provides at present.

4, extremely low ratio of height to diameter (0.2～0.3) can make filler that orderly relatively largely arrangement is arranged, and has improved flux and mass-transfer efficiency greatly.Area is difficult to effectively play a role and influence flux about when having avoided common fillers to couch.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

A kind of flat ring as filler comprises ring, it is characterized in that: encircle and be flat-shaped 2; At the perisporium of flat-shaped ring, evenly offer three rectangle circular holes 1; There is a grade limit to be separated by between the two adjacent rectangle circular holes, between two grades of limits, connects the circular-arc muscle sheet 3 that protrudes to the circle center, form and flat ring is separated into four parts by three circular-arc muscle sheets; Circular-arc muscle sheet middle part has the circular-arc aperture 4 of rectangle; On the limit, two holes of the circular-arc aperture 4 of the rectangle of circular-arc muscle sheet 3, the right angle sheet 5 that constitutes 90 degree with the limit, hole is arranged respectively.Described flat ring 2 as filler, the high ratio with the ring footpath of its ring is 0.2-0.3.
