Abstract
The utility model relates to a dumped packing for a spherical built-in impeller, particularly to a dumped packing used in a packing tower of chemical engineering equipment. The dumped packing for the spherical built-in impeller comprises a spherical shell (1), impeller mounting shafts (3) and semi-open type impellers (4), wherein a plurality of long and thin pores (2) are uniformly formed in the outer wall of the spherical shell; the impeller mounting shafts (3) are in three directions of X-axis, Y-axis, and Z-axis; the semi-open impellers (4) are symmetrically mounted on the impeller mounted shafts (3); the semi-open impellers (4) are provided with circular arc-shaped impeller blades (5); the diameter of each semi-open type impeller (4) is as half as the radius of the spherical shell (1); the semi-open impellers (4) are internally arranged in the spherical shell (1); the semi-open type impellers (4) are regularly arrayed inside the spherical shell; two impellers are symmetrically distributed in the directions of the X-axis, Y-axis and the Z-axis; when gas-liquid passes thorough the interior of the spherical shell, the semi-open type impellers (4) are driven to rotate and the surface of the liquid membrane is promoted to renew; moreover, the semi-open type impellers (4) enlarges the area of mass transfer, so that the improvement of the mass transfer efficiency is facilitated.
Description
Technical field
The utility model relates to a kind of spherical built-in impeller dumped packing, especially for the dumped packing in chemical industry equipment packed tower.
Background technology
In China, tower is as one of most important equipment in chemical industry, petrochemical industry and oil refining production, and it can make to carry out close contact between gas-liquid or liquid-liquid diphase, reaches the object of interphase mass transfer and heat transfer.Can in tower, complete common unit operations has: rectifying, absorption, desorb and extraction etc.Along with the development of chemical industry, as the important component of packed tower, the kind of filler is also constantly being enriched.Filler market is very large at present, and a lot of scholars are just being devoted to improve packing technique, and have developed the filler that many quality are very high.But high-quality filler is too expensive, is not suitable with most application.So, need development cost more economical, keep the material of organism material performance simultaneously.
The filler that China or is inventing at present mainly divides two large classes: dumped packing, structured packing.Dumped packing can divide metal material and plastic material.Product has interior curved arc shape rib flat ring, rectangular saddle ring, cascade ring, the flat ring of double-turnup (CMR), Pall ring, Raschig ring etc.Be applied at present nearly hundred kinds of fillers in industry, and constantly have new packing to be developed appearance.Market has the basic demand of filler: mass-transfer efficiency is high, requires filler that large gas-liquid contact face can be provided.Require to there is large specific area, and require filling surface to be easy to be soaked by liquid.Only have wetting surface to be only gas-liquid contact surface.Production capacity is large, and gas pressure drop is little.Therefore require the voidage of packing layer large.Do not move and cause bias current and channel.Durable in use have good corrosion resistance, higher mechanical strength and a necessary heat resistance.Draw materials easily, low price.
Therefore, need a kind of product all relatively having superiority in mechanical strength, source, manufacture and price.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model is: overcome the deficiency in prior art, proposed a kind of durable in usely, have the filler of higher mechanical strength and the advantage such as heat-resisting.
Technical solution of the present utility model is achieved in that the utility model relates to a kind of spherical built-in impeller dumped packing, especially for the dumped packing in chemical industry equipment packed tower.Spherical built-in impeller dumped packing comprises spherical shell (1), impeller installation shaft (3) and impeller (4).On described spherical shell outer wall, be evenly distributed with elongated porosity (2).Described impeller installation shaft (3) is divided into three directions of X, Y, Z axis.Impeller installation shaft (3) is upper, is symmetrically installed with half-opened impeller (4).Half-opened impeller (4) is upper, has circular arc impeller blade (5).The diameter of impeller (4) is the half of spherical shell (1) radius.In the built-in spherical shell of half-opened impeller (4) (1), impeller 4 internal rule arrange, in X, Y, Z axis all directions, respectively have two symmetrical.
Due to the utilization of technique scheme, the utility model compared with prior art has with a little following:
Spherical built-in impeller dumped packing, its profile is spherical, available plastic injection-moulded, ceramic sintering or metal material are made, spheroid is that hollow surface has a lot of slot gaps, due to the perforate of ball wall, greatly improve the utilization rate of the ball inner surface in space in ball, make gas-flow resistance little simultaneously, Gas-Liquid Dispersion is even, in addition pore size can be according to working condition (temperature, pressure, liquid viscosity etc.) select, due to the symmetry of spherical structure, filler loading density is even, be difficult for producing hole or bridge formation, so Gas-Liquid Dispersion performance is good, reduce gas by the resistance of packing layer.Impeller is arranged at internal rule, and in the time that gas-liquid is inner by spheroid, impeller is rotated, and promotes the Surface Renewal of liquid film, and impeller also increases mass transfer area simultaneously, is conducive to the raising of mass-transfer efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1: spherical built-in impeller dumped packing structural representation 1-spherical shell, the even elongated porosity of 2-, 3-impeller installation shaft, 4-half-opened impeller, 5-half-opened impeller circular arc vane.
Accompanying drawing 2: the built-in blade wheel structure schematic diagram 4-half-opened impeller of spherical built-in impeller dumped packing, 5-half-opened impeller circular arc vane, 6-impeller centre bore.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described
Spherical built-in impeller dumped packing, outer wall is spherical shell (1), global shell surface uniform has a lot of slot gaps (2), due to the perforate of ball wall.When gas-liquid mixture enters spheroid, the great utilization of the ball inner surface in space in ball, gas-flow resistance is less, and Gas-Liquid Dispersion is even.Due to the symmetry of spherical structure, filler loading density is even, is difficult for producing hole or bridge formation, so Gas-Liquid Dispersion performance is good, reduces gas by the resistance of packing layer.Half-opened impeller (4) is arranged at internal rule, upper each symmetrical two impellers (4) of installing of X, Y, Z axis (3), in the time that gas-liquid is inner by spheroid, impeller is rotated, promote the Surface Renewal of liquid film, impeller also increases mass transfer area simultaneously, is conducive to the raising of mass-transfer efficiency.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all according to the present invention, Spirit Essence does equivalence variation or modifies, within all should being encompassed in protection scope of the present invention.
