Abstract
A fine-grained grid packing comprises the sheet material for separation, which is characterized in that the sheet material is made of plastic. The surface of the sheet material is distributed with the fine grain, moreover, a plurality of parallel sheet materials form the grid packing through binding rod combining together. The fine-grained grid packing has a light weight, a good transmission of quality and heat, longevity and good block-resistance ability.
Description
Technical field
The utility model relates to the filler that uses in a kind of chemical industry equipment tower.
Background technology
Most of small and medium ammonia synthesis plants of China and coke-oven plant are in semiwater gas and conversion gas purification process, with recirculated water or solution chemistry absorbing and removing dust, tar and hydrogen sulfide.Semiwater gas and conversion gas all have impurity and sulphur cream to separate out in cooling, dedusting and sweetening process, are deposited on traditional filling surface, and the tower internals resistance is increased, and the cycle of operation of tower shortens significantly, has a strong impact on synthesis ammonia system long period, safe operation.For overcoming this difficult problem; small and medium ammonia synthesis plant and coke-oven plant all adopted wooden grid or bamboo grid filler in the past; but wooden grid filler is to adopt northeast high-quality Korean pine to make after ungrease treatment; workload is big; service life is short; and at present northeast Korean pine source is more and more difficult, from environmental protection, reduce soil erosion to the stage that non-stop cutting down.There is same problem in bamboo, and owing to the reason of material makes inner-tower filling material damaged easily, service life is short; The filler screen is thicker, causes the specific area of filler less, and voidage is little, the mass-and heat-transfer weak effect.
In recent years, along with progress of science and technology, the novel synthetic material emerge in multitude makes development of new, the efficient filler that is suitable for become possibility.Just in this case, my company has developed this microgroove grid packing national conditions, that can be widely used in small and medium ammonia synthesis plant and coke-oven plant's semiwater gas and conversion gas mass-and heat-transfer that is fit to very much.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of in light weight, liquid is good from distribution capability, mass-and heat-transfer efficient height, the life-span is long, anti-blocking is strong microgroove grid packing.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of microgroove grid packing, it includes the sheet material that is used for separating, it is characterized in that described sheet material is to adopt plastics to make, surface distributed at sheet material has microgroove, and the parallel sheet material of polylith combines by the connecting rod connection and has constituted filler.
Useful is to punch connecting rod employing plastic screw on the above-mentioned plate surface, by distance sink tube and nut, with each sheet material according to the design separating distance and couple together, be convenient to the production and assembly of filler like this, and the spacing of each sheet material adhered to specification.
Useful is, above-mentioned sheet material connects into that the cross sectional shape of the cross sectional shape of every dish filler and tower is suitable, and the height of every dish filler is at the 80-150 millimeter, and convenient the use improved the mass-and heat-transfer effect.
Useful is, above-mentioned every dish filler certain angle that staggers up and down, angular range increases the turbulence state in tower of gas and liquid at 40-50 °, increase conduct heat, the intensity of mass transfer.
At last, described plastics can polypropylene or other plastics, the microgroove of plate surface is the Z type of level, the Y type of inclination and the X type of intersection, the lines width is preferably 0.02～0.2 millimeter scope, the degree of depth is 0.2～0.8 millimeter scope, under different media, increase the turbulance of gas and liquid, improve the effect of mass-and heat-transfer.
Compared with prior art, advantage of the present utility model is: because plastic density such as polypropylene is little, be subjected to Temperature Influence, therefore the proportion of PP generally only about 0.9 can reduce the weight of tower internals significantly, improves the height of packing layer; The screen of microgroove grid packing is that polypropylene material is made, and the intensity height is in light weight, and therefore, screen can make thin than wooden or bamboo, can increase substantially the specific area of filler like this, and output of column is increased; There is microgroove on microgroove grid packing surface, can effectively increase the turbulance of the flow regime of gas and liquid, thereby can increase substantially the mass-and heat-transfer effect of gas and liquid, and then improves the production capacity of device; Polypropylene is a chemical synthetic material, and resistance to corrosion is strong especially, can prolong the service life of tower internals significantly, thereby improves the safety in production cycle of whole device; Because the screen of microgroove grid packing and tower section are to hang down really, have therefore eliminated the total wall flow phenomenon of random packing and ripple packing substantially, can make full use of the sectional area of tower, the effective cross-section of tower is increased; Therefore, the microgroove grid packing has advantages such as in light weight, that flux is big, pressure drop is low, anti-blocking is strong, is to be fit to very much the occasion use that impure more gas transfer conducts heat, and has wide promotion prospect.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Anticipate as shown in the figure, filler of the present utility model is a kind of microgroove grid packing, it is by polypropylene board 1, plastic screw 2, plastics distance sink tube 4, nut 3 critical pieces such as grade are formed, they need pass through certain processing technique, main is to adopt polypropylene (PP) to replace traditional wooden grid or bamboo grid to make sheet material 1, concrete processing is: elder generation's microgroove 12 on the Surface Machining of polypropylene board 1, microgroove can be a level, the shape that tilts and intersect, referring to Fig. 1, the lines width is preferably 0.02～0.2 millimeter scope, the degree of depth is 0.2～0.8 millimeter scope, the best be width at 0.1 millimeter, the degree of depth is at 0.5 millimeter, polypropylene board 1 with same thickness is cut into desired width again, get hole 11 then on the polypropylene board 1 that cuts, put on plastic screw 2, the not necessarily whole plastics pole of this screw rod 2 is the screw thread pole, at least be to mold screw thread in the end, it is fixedly connected to be convenient to nut 3, and 1 plastics distance sink tube 4 with different length of sheet material is separated, and makes it satisfy technology or designing requirement.See accompanying drawing 4, then, by plastics or metal nuts 3, the sheet material 1 that polylith is parallel assembles, and has constituted filler of the present utility model.
The microgroove polypropylene grid packing that processes is placed in the tower, and every size is determined according to the size of tower diameter, manhole at last.The cross sectional shape of every dish filler and the cross sectional shape of tower are suitable, and the height of every dish filler is decided by technology Calculation, and a dish is 80-150mm.For increasing the mass-and heat-transfer intensity of gas and liquid, arrange between levels microgroove grid packing to have a certain degree that angle is 40-50 ° of scope, the best is 45 °, the microgroove grid packing just constitutes the media of gas and liquid mass-and heat-transfer in tower like this.
