Abstract

The utility model relates to a cascade mini ring random packing, which belongs to the technical field of gas-liquid and liquid-liquid mass transfer separation devices in petroleum refining, petrochemical, chemical, light and environmental protection industries. The packing presents a four-layer cascade, a first step and a fourth step are respectively formed by a semicircular saddle, a second step and a third step are respectively formed by two semicircular saddles which are respectively positioned on two sides of a plane formed by a first connecting edge and a second connecting edge, and the two semicircular saddles intersect at the center of a packing ring to form an X-shaped structure supported in the middle of a ring body. The cascade mini ring random packing has the advantages that two ends of the four-layer cascade are connected together so as to increase self strength of the packing and also increase specific surface area and spraying spots of the packing, thereby increasing production capacity and mass transfer efficiency; the second step and the third step are mutually connected through a middle connecting piece to be supported in the middle of the ring body so as to lead the gas-liquid to be uniformly distributed; and the second step and the third step intersect mutually in the middle of the packing, thereby effectively resolving the problem of mutual nesting of packings.

Description

A kind of multi-step ring bulk loading filling material

Technical field

The utility model relates to a kind of multi-step ring bulk loading filling material, belongs to gas-liquid, the liquid liquid mass transfer separation equipment technical field of oil refining, petrochemical industry, chemical industry, light industry and environment-protecting industrial.

Background technology

Gas-liquid, liquid liquid mass transfer separation equipment field at oil refining, petrochemical industry, chemical industry, light industry and environment-protecting industrial, filler is the critical piece in rectifying, absorption, washing, the extraction tower, it generally can be divided into structured packing and dumped packing, dumped packing is because processing and manufacturing is fairly simple, installation and removal are convenient, be convenient to clean, thereby wider range of application is arranged.

Using more at present in China's industry, dumped packing is annular packing or saddle ring filler, for example Pall ring, ring intalox etc., these fillers are limit by configuration, its manufacturing procedure is comparatively complicated, the general operation ability moulding that needs at least more than three roads or three roads, and its overall specific area is less, and the spray point is few, and production capacity and mass-transfer efficiency still are subjected to certain limitation.

The applicant has proposed a kind of new multi-step ring bulk loading filling material in application number is 200810119362.7 Chinese patent.This filler processing is simple, by twice even procedure processing, one-shot forming; Surfaces externally and internally is fully unlimited, and the interior tendon sheet is evenly cut apart space in the ring, and the spray point is many, and liquid dispersion is effective.By in the experiment tower of diameter 600mm, test and the Pall ring of same specification and ring intalox relatively, treating capacity and ring intalox are suitable, but mass-transfer efficiency is higher more than 50% than ring intalox.

But constitute in four parallel ladders of this filler, second ladder and the 3rd ladder are made up of two semi-ring saddles respectively, two semi-ring saddles lay respectively at the same side on the plane that is formed by first fillet and second fillet, do not have alternating share, are easy to generate axial intussusception phenomenon.Intussusception not only increases the filler filling number in the unit volume, and can cause reducing of the interior gas passage of tower, influences the disposal ability of tower.

Summary of the invention

The purpose of this utility model is to propose a kind of multi-ladder dumped packing, change the structure of existing multi-ladder dumped packing, make it can adapt to gas-liquid contact processes such as rectifying, absorption, can be applied to extraction again and wait liquid liquid contact mass transfer process, improve the combination property of filler, and simplify the manufacturing procedure of filler.

The multi-step ring bulk loading filling material that the utility model proposes, both wings are first fillet and second fillet, first fillet is connected first ladder, second ladder, the 3rd ladder and four-step with second fillet from both sides, first ladder, second ladder, the 3rd ladder and four-step are parallel to each other, constitute four layers of ladder, described first ladder is begun by first fillet, comprises first inner arc, first outer arc, second inner arc, second outer arc, the 3rd inner arc, finishes to second fillet; Described second ladder is begun by first fillet, comprise first inner arc half, the first transition outer arc, first straightway, second straightway, the second transition outer arc and the 3rd straightway, finish to second fillet; Described the 3rd ladder is begun by first fillet, comprise the 6th inner arc half, the 3rd transition outer arc, the 4th straightway, the 5th straightway, the 4th transition outer arc and the 6th straightway, finish to second fillet; Described four-step is begun by first fillet, comprises the 6th inner arc, arc, the 5th inner arc, the 3rd outer arc and the 4th inner arc all round, finishes to second fillet; Described second ladder is connected by brace with the 3rd ladder, and staggered in the central authorities of packing ring, forms the X-shaped structure, is supported in annular central; From the front of filler, be the ring-type of forming by a plurality of saddle types, two big semi-ring saddles up and down of filler are first ladder and four-step, not in one plane, four little semi-ring saddles in the ring are intersected in the brace of filler central authorities, form the X-shaped structure; Filler becomes four layers of ladder, and wherein first ladder and four-step are made up of a semi-ring saddle, and second ladder and the 3rd ladder are made up of two semi-ring saddles respectively, and two semi-ring saddles lay respectively at the both sides on the plane that is formed by first fillet and second fillet.

The multi-step ring bulk loading filling material that the utility model proposes, its advantage is: the two ends of four layers of ladder link together, form an integral body, increased the intensity of filler itself, each line segment that constitutes ladder is by the camber line smooth connection, can increase the specific area and the spray point of filler again, to improve production capacity and mass-transfer efficiency.Second ladder and the 3rd ladder interconnect by the brace of centre, are supported in ring body central authorities, from radially evenly cutting apart area the ring, also from axially evenly cutting apart filling space, gas-liquid can evenly be distributed.Simultaneously, two semi-ring saddles that constitute second ladder and the 3rd ladder lay respectively at the both sides on the plane that is formed by first fillet and second fillet, and central authorities are interlaced at filler, efficiently solve the mutual intussusception problem between the filler that has patent.
