Description

Polygon water conservancy diversion grid filler

Technical field

The utility model relates to the filler in a kind of chemical tower, and more particularly, it relates to the polygon water conservancy diversion grid filler that a kind of packed tower is used, and can be widely used in the tower shape equipment in environmental protection, chemical industry, the petroleum industry.

Background technology

Packed tower is a kind of consersion unit of traditional gas-liquid contact mass transfer (heat transfer), and wherein, filler is the vitals of mass transfer (heat transfer), and its structural design directly has influence on the quality of its mass transfer (heat transfer) and the long-term stability operation of device.

China's small and medium ammonia synthesis plant carries out dedusting, decoking, cooling with recirculated water in semiwater gas and conversion gas purification process, or carries out chemical absorbing with solvent and remove harmful chemicals such as hydrogen sulfide.Semiwater gas and conversion gas all have impurity and sulphur cream to separate out in cooling, dedusting and sweetening process, be deposited on the surface of conventional filler, cause the obstruction of tower, make resistance increase, mass transfer (heat transfer) weak effect of gas-liquid skewness, internals in the tower, install for a long time, move with security and stability thereby influenced.For many years, synthesis ammonia plant and coke-oven plant have adopted the filler of various types to seek to deal with problems in succession.Wooden grid or bamboo grid filler are arranged, the plastic grill packing that adopts the screw rod serial connection is also arranged, adopt the methods such as plastics random packing of various ways such as Pall ring, cascade ring, rectangular saddle ring to solve this problem in addition.But wooden grid filler or bamboo grid filler not only relate to the material source problem, relate to also that wooden grid filler is initial to use the complexity of being run into and obstinate skimming processes and both problems such as heaviness is damaged easily, service life is short; Though the plastics random packing can reach mass transfer (heat transfer) effect preferably, exist easily stifled tower, resistance easily to raise, problems such as with short production cycle and easy fragmentation; With the plastic grill packing of screw rod serial connection, owing to make structural factor, the structural stability and the compressive resistance of filler are poor, and specific area is little, have influenced the up to standard of gas purification degree.

The utility model content

The utility model is at the deficiencies in the prior art, provide a kind of under operating condition liquid from distribution capability and good guide performance, surface infiltration degree, actual effective surface area utilization rate, mass transfer (heat transfer) efficient height, long service life, structural stability is good, the polygon water conservancy diversion grid filler that the tower resistance is little.

The utility model is realized above goal of the invention by implementing following technical scheme:

Polygon water conservancy diversion grid filler comprises screen 1 in the form of sheets, polylith screen 1 component units grid 2, and element grid 2 is polygon, and a plurality of element grids 2 are formed the grid filler, are provided with diversion component 3 in the two sides of screen 1.

As an example preferably, described diversion component 3 is the vertical microgroove of concave-convex.

As another example preferably, the continuous disposed at equal distance of the vertical microgroove of described concave-convex.

As another example preferably, the vertical microgroove of described concave-convex is the rectangle microgroove.

As another example preferably, the vertical microgroove of described concave-convex is the circular arc microgroove.

As another example preferably, the vertical microgroove of described concave-convex is the zigzag microgroove.

As another example preferably, the vertical microgroove of described concave-convex is vertical with the bottom surface 4 of screen 1.

As another example preferably, described diversion component 3 is convex point or spill point.

As another example preferably, described element grid 2 is equilateral pentagon.

As another example preferably, described element grid 2 is equilateral hexagon.

The specific embodiment

In Fig. 1, polygon water conservancy diversion grid filler comprises screen 1 in the form of sheets, polylith screen 1 component units grid 2, and element grid 2 is polygon.The quantity of the screen 1 of component units grid 2 is more than or equal to three.When the quantity of screen 1 was three, the vertical view of element grid 2 was triangular in shape, and the like, such as pentagon, hexagon etc.A plurality of element grids 2 are formed the grid filler.This grid filler is with polypropylene or RPP or other plastics one-time cast-formings.Because directly fixedly connected mutually between the screen 1 of this filler, the effective intensity of reinforcer, the structural stability when improving its work.Element grid 2 is good with equilateral polygon or rectangle, helps the manufacturing and the installation of filler.In the two sides of screen 1 diversion component 3 is set, with the specific area of effective raising screen 1 with to the guide performance of gas-liquid, and then can improve the specific area of whole filler and to the guide performance of gas-liquid, make this filler when work, have even distribution performance of better fluid and guide performance, improve liquid filling surface from distribution capability, make liquid on the screen surface moistening well formation film, liquid reaches intact wettability at filling surface, improves mass transfer (heat transfer) efficient.Diversion component 3 is the concave-convex microgroove that is arranged at the two sides of screen 1, such as rectangle, circular arc, zigzag etc., equidistant vertical setting continuously on screen 1, and it is vertical with the bottom surface 4 of screen 1, make screen 1 in effective increasing specific surface area, further strengthen its guide performance, and can improve the manufacturability of this filler when making, be convenient to manufacture gas-liquid.

Diversion component 3 also can be a convex or spill point, such as the point-like thing of star point, circular point, triangle form point or other form, and size, shape and the arrangement mode etc. that can come selected element according to the technology and the actual needs of manufacturing.

Fig. 2, Fig. 3 all are partial enlarged drawings of Fig. 1, and difference is the form difference of microgroove.In Fig. 2, be provided with the vertical microgroove of zigzag concave-convex in the two sides of screen 1.In Fig. 3, be provided with the vertical microgroove of concave-convex of rectangle in the two sides of screen 1.

In the accompanying drawings, do not draw and be provided with the schematic diagram of the vertical microgroove of concave-convex of circular arc in the two sides of screen 1.Under the situation that vertically the microgroove width is identical, have the specific area maximum of the screen 1 of rectangle microgroove, the circular arc microgroove takes second place, zigzag microgroove minimum.Aforesaid concave-convex microgroove is along the continuous disposed at equal distance in the two sides of screen 1, promptly between the convex of each microgroove or between the spill or the distance between the concave-convex sum equate and arrange continuously.

Fig. 4 is the structural representation that has the screen 1 of vertical microgroove.Among the figure, the concave-convex microgroove is vertical with the bottom surface 4 of screen 1.

This filler is compared with other existing plastic grill packing, have that specific area is big,, mass transfer (heat transfer) efficient height, the long service life good from distribution capability of liquid, the advantage such as structural stability is good, the tower resistance is little, filler weight is light, be suitable for containing the occasion of more polymictic gas-liquid mass transfer, have preferably market prospects.
