Abstract
The utility model relates to a grid stuffing that is applicable to tower-shaped devices used in environmental protection, chemical industry and oil industry. The utility model is provided with a plurality of parallel grid plates (1), on which two or more perforations are arranged, a distance fixing tube (2) is arranged between every two grid plates and pull rods (3), of which the number is corresponding to the number of the perforations, and the pull rods (3) go through the distance fixing tube alternatively, and the two ends of the pull rods are fixed and connected into a whole. The utility model is characterized in that the two ends of the plastic pull rods (3) are provided with plastic welding seams (4) used for fixing the plastic grid plates. The grid plates of the utility model has small thickness (only one third of the thickness of wooden lattice stuffing), smooth surface, 30 percent of promoted throughput, stable integrity, high specific surface area when in use (being promoted to 78 m<2>/m<3> from 55m<2>/m<3> of pine), small resistance (descends by about one third) and long service life, thereby being a practical and efficient stuffing.
Description
Technical field
The utility model relates to a kind of grid packing, is applicable to the tower shape equipment in environmental protection, chemical industry, the petroleum industry.
Background technology
Use wooden grid filler in the prior art, not only efficient is low always, and consumes a large amount of timber resources.Chinese patent CN2408963 discloses a kind of " cooling tower bamboo grid net packing ", it comprises some parallel bamboo chips, between per two bamboo chips, be provided with sleeve pipe in order to the bamboo chip spaced at equal intervals, connector alternately passes fixed via and the sleeve pipe of being located on the bamboo chip, the other end at connector is installed with fixture in order to the bamboo chip secured in parallel, is combined into an integral body.This filler wood substituted by bamboo has been saved valuable timber resources, but still has 3 deficiencies: the one, and the bamboo quality is loose, and the bamboo chip surface ratio is more coarse, in use is easy to long-pending reaction enclosure thing and influences flux, results in blockage.The 2nd, the fixedly defective tightness of connector and bamboo chip makes that the globality of filler is stable inadequately, and light easy deformation then is heavy then fall apart.The 3rd, for proof strength, the bamboo chip of use is thicker, and this has lost the net sectional area of reaction tower preciousness.
Summary of the invention
The utility model technical issues that need to address are to improve the plate surface smoothness, raising filler resistance to overturning and reduction screen thickness.
Grid packing of the present utility model, some parallel plastics screens are arranged, plural perforation is arranged on the plate, between per two blocks of screens distance sink tube is arranged, other has the pull bar corresponding with the perforation number alternately to pass plate---pipe, two ends fixedly make it connect into an integral body, are characterised in that there is the plastics weld seam at the pull bar two ends, fix the plastics screen.Timber and bamboo wood being carried out modified, again plastic-blasting is carried out on the surface and handle, be that to make be a kind of method that its surface has plastics fineness, but cost is higher.Plastics then are to meet the only material that the utility model fineness requires, and in use long-pending reaction enclosure thing significantly reduces.Owing to select plastics for use, make the fixing of pull bar two ends can use Plastic Welding, the plastics weld seam is arranged, both improved the intensity and the globality of filler greatly, also reduced the thickness of screen simultaneously, generally be no more than 6mm.Having some through holes on screen, then is in order to increase contact area.
The utility model screen thickness little (only be wooden grid filler 1/3), smooth surface, treating capacity improves 30%, and globality is stable, and the specific area height is (from the 55m of pine during use
2/ m
3Bring up to 78m
2/ m
3), resistance little (descending nearly 1/3), the life-span is long, is a kind of practicality, filler efficiently.
Description of drawings

Fig. 2 is the partial top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1.See Fig. 1, Fig. 2, this routine grid packing has some blocks of parallel plastics screens 1, and thickness is 4mm.Several perforation and some through hole 1-1 are arranged on the screen.Between per two blocks of plastics screens distance sink tube 2 is arranged.Other has the pull bar 3 corresponding with the perforation number alternately to pass plate one pipe, and two ends have plastics weld seam 4 to make it connect into a stable whole.This routine product uses in the semiwater gas desulphurizing tower of diameter of phi 4000mm, and grid packing loading height 20M is divided into five sections.Former semiwater gas import H
2S 1.5g/m
3, tolerance is 44000m
3In/time, be H through transforming the back outlet
2S 0.06g/m
3, absorption efficiency reaches 96%, and tolerance is increased to 52000m
3In/time, full tower resistance has reduced 1/3.
The height of plastic plate in the utility model, the length of distance sink tube is selected by concrete process conditions.
Claims (3)
1, a kind of grid packing, some parallel screens (1) are arranged, plural perforation is arranged on the plate, between per two blocks of screens distance sink tube (2) is arranged, other has the pull bar (3) corresponding with the perforation number alternately to pass plate---pipe, two ends fixedly make it connect into an integral body, it is characterized in that there is plastics weld seam (4) at described pull bar (3) two ends, fix the plastics screen.
2, grid packing according to claim 1 is characterized in that described screen (1) thickness is no more than 6mm.
3, grid packing according to claim 1 and 2 is characterized in that having on the described screen (1) some through holes (1-1).
