Abstract
The utility model relates to a packing consisting of a plurality of protruded packing sheets. The packing is formed by laminating a plurality of packing sheets, each packing sheet is characterized in that a front side and a back side of a sheet are alternatively bent to form a plurality of projections with a notch arranged respectively on two sides, or a plurality of projections with a notch arranged respectively on two sides are formed on a single surface of the sheet at intervals, each projection is formed by a region (MNPO), and the region MNPO is an area encircled by two notches corresponding to each other and joint lines between corresponding ends on the two notches. The packing has following advantages that the notches at two sides of the projections which are formed by bending the front side and the back side of the packing sheet are communicated with each other, the gas phase transverse mixing capacity is improved, the liquid can easily flow to the back surface of the packing sheet in the flowing process, and the surface of the packing is adequately utilized. Since the surface of the packing sheet is not provided with a hole, the mass transfer area is not lost. The discontinuity of the projections also improve the mass transfer effect, the liquid phase can be continuously updated on the surface of the packing, and the mass transfer process can be favored.
Description
Technical field
The utility model belongs to chemical industry equipment, is applicable to separation process industrial technology field, particularly relates to the filler that a kind of packing sheet that is made up of a plurality of convexities is formed.
Background technology
Separation engineering is the essential industry process of chemical industry, and gas-liquid mass transfer (contact) equipment is a most important component in the separation process.Gas-liquid mass transfer (contact) equipment occupies 80% proportion in the aggregate investment of petrochemical industry commercial plant; And occupied permanent plant almost accounts for more than 50% in investing in other industrial circle, so people extremely pay attention to the utilization and the research of gas-liquid mass transfer (contact) equipment all the time.
Gas-liquid mass transfer (contact) equipment generally is divided into two big types: one type is plate column, and one type is packed tower.The apparatus characteristic of packed tower and plate column have diverse form.
Packed column technology is in continuous development in recent years, and filler is the principal element that influences the packed column technology index.The structured packing that with the mellapak packing is representative plays an important role to the development that promotes packed column technology.
The corrugated filler of plate is present the most widely used filler; It forms block filler by the corrugated packing sheet that slices vertically are stacked together; Packing box (shape of packing box is generally circle) by shape in filling block recomposition and the tower is coincide is layered in packing box in the tower at last.Sometimes also can packing sheet directly be assembled into packing box, and send into the assigned address in the tower by an end of tower, the thickness of packing box depends on and is generally 100mm-300mm by the width of packing sheet.In the tower of minor diameter or other special material, the thickness of packing box also can be different sometimes.
Fig. 1 is a kind of prior art packing sheet structural representation commonly used.As shown in Figure 1, this packing sheet 4 is corrugated, thus be called the corrugated plate packing sheet again, and the surface is formed with a plurality of perforates 5, and the ripple inclination angle is generally 30 ° and 45 °.Corrugated plating is that it can provide bigger specific area, lower resistance, bigger disposal ability as the significant advantage of filler.There is following point in this packing sheet: one, packing sheet surface perforate is laterally to mix for the gas phase that obtains horizontal direction to greatest extent, and is inhomogeneous with the phase concentrations of improving on same horizontal plane.Another effect can make partially liq passed perforate 5 and flowed to the back side by top, but higher percent opening can cause mass transfer area to reduce, so percent opening is restricted.Percent opening is controlled between the 5-12% generally speaking, otherwise can influence efficient.Two, the ripple cross sectional shape is generally triangle, and the length of ripple is that the end along a certain definite angle from packing sheet extends to the other end, when drop drops on the corrugated filler tablet surface; Can go downstream along upper surface; Be difficult to pass lip-deep perforate 5 and flow to the back side, the back side of ripple just is difficult to wetted, only lower at liquid phase viscosity; And under the bigger situation of surperficial liquid holdup, just might on part perforate 5 positions, realize.Filling surface just can not be fully utilized like this.Three, the wavy channel that tilts, the corrugated plating face that percent opening is lower causes bigger resistance to uprising gas, directly influences technical indicators such as packed tower energy consumption and treating capacity.
Summary of the invention
The purpose of the utility model is to provide a kind of can greatly improve the gas-liquid mass transfer ability, reduces gas phase drag greatly, and has the filler of being made up of a plurality of protruding packing sheets of the mass transfer surfaces of fullest.
In order to achieve the above object; The filler of being made up of a plurality of protruding packing sheets that the utility model provides is to be stacked together and to be constituted by the multi-disc packing sheet that vertically is provided with, and described packing sheet is to bend and form a plurality of both sides and have otch MN, the convexity of OP in that the tow sides of its rectangle plate are staggered; Or standoff distance forms a plurality of both sides and has otch MN on the single face of plate; The convexity of OP, its protrusions are to be made up of regional MNPO, and regional MNPO then is by the corresponding in twos otch MN that on plate, forms; OP and two otch MN, the area that line MO and the NP between the last opposite ends of OP surrounded constitutes.
Described otch MN, OP are any in straight line, camber line, broken line and the teeth outline.
Otch MN, OP can form symmetry or asymmetric, and two otch can be different curves.
Described otch MN, the line MNOP between the OP the two ends outwards track of motion are a plane, normal U, the V on this plane be parallel to the straight line YZ of minor face AB and the angle between the ST is respectively α and β, and the angle of α and β is spent the while less than 90 ° greater than 0; As otch MN, when OP is parallel, α=β; As otch MN, when OP is not parallel, α ≠ β.
Described otch MN, the line MN between the OP two ends, the OP outwards formed flat shape of track of motion are triangle, semicircle, half elliptic, trapezoidal, rectangle or truncated cone-shaped.
The a plurality of convexities that form on described plate single face or the tow sides are lined up many rows, and stagger each other or align in the position between adjacent two row's convexities.
The shape of described a plurality of convexities is symmetry or asymmetric setting on plate single face or tow sides.
Be between the described multi-disc packing sheet and be arranged in parallel, contacted convexity is the intersection mode and arranges on the adjacent packing sheet.
Compared with present technology the filler of being made up of a plurality of protruding packing sheets that the utility model provides has advantage: 1, because the protruding both sides otch that is staggered to form up and down on the packing sheet connects, therefore improved the horizontal mixed ability of gas phase greatly.2, flow is easy to flow to the back side of packing sheet in flow process, so that filling surface can access is fully wetting.Because packing sheet not perforate of surface can not lost mass transfer area.3, owing to protruding discontinuity, improved the effect of mass transfer, liquid phase can constantly be upgraded at filling surface, more helps the carrying out of mass transport process.4, staggered up and down convexity of arranging is minimum to the resistance that gas phase causes, and can improve the gas handling capacity, reduce gas phase through resistance, so the efficient of packed tower, energy consumption and treating capacity three technology index can improve significantly all.
