Abstract
The utility model relates to packing material, in particular to thin-film packing material with high heat-transfer property used for a cooling tower. The packing material is formed through the lap joint of thin-film packing pieces, an internal jointing part and an external jointing part are correspondingly arranged on each packing piece, the adjacent two packing pieces are embedded and jointed through the internal and external jointing parts, plenty of kink waves are formed on all the packing pieces, a plurality of small continuous and convex cambered surfaces constitute the wave surfaces of the kink waves, and water breaking segments are arranged on the kink waves. Compared with the present thin-film packing material used for cooling towers, the heat-transfer surface area of the thin-film packing material with high heat-transfer property is increased, the heat transfer and the mass transfer coefficient are all greatly enhanced, and therefore the thermal performance is obviously improved. Because the thermal performance of the packing material is good, the design air quantity can be reduced accordingly, the water tricking cross section resistance force will be reduced further under the operating condition of low water tricking density, and compared with the conventional design value, the resistance force design value of the packing material has greater declining amplitude.
Description
Technical field
The utility model relates to a kind of filler, especially relates to a kind of high thermal conductivity cooling tower diaphragm type filler.
Background technology
The disposal ability of the nucleus equipment cooling tower of industrial cycle water cooling system has crucial effect to the energy-saving and cost-reducing and economy of product.Packing directly influences the Technological Economy and the floor space of cooling tower as the height of its performance of vitals of cooling tower cooling.Carrier performance is high more under square one, and column area is more little; Carrier performance is low more, and column area is big more.The performance of filler is mainly reflected in its heat, matter is transmitted performance and flowing resistance size aspect.In general, these two faces oppose, and the raising that instant heating, matter are transmitted performance can strengthen flowing resistance usually.And filler should be that heat, matter are transmitted the performance height but the not corresponding thereupon increase of flowing resistance efficiently.The kind of packing is a lot, comprises that drip, diaphragm type, drop diaphragm type etc. are multiple.At present, film is owing to its thermal performance better is widely adopted.
The utility model content
The technical problems to be solved in the utility model is: for heat, the matter that can further improve present cooling tower film are transmitted performance, do not increase simultaneously its flowing resistance again, provide a kind of with present cooling tower film filler to compare, it is higher that heat, matter are transmitted performance, the cooling tower diaphragm type filler that flowing resistance is lower.
The technical solution adopted in the utility model is: a kind of high thermal conductivity cooling tower diaphragm type filler, splice by the film packing sheet and to constitute, correspondence is provided with the negative and positive junction surface on each packing sheet, adjacent two packing sheets engage by the intercalation of negative and positive junction surface, be formed with numerous folding ripples on each film packing sheet, the folding ripple is provided with the one's water breaks joint; Folding wave-wave face is made of numerous little cambered surfaces continuous, projection.
In order further to reduce the resistance of filler, be provided with slot between the adjacent films packing sheet.
Splice and be assembled into integrally-built steadiness behind the filler in order to improve the film packing sheet, negative and positive junction surface of each row formula that staggers distributes and is provided with on the described film packing sheet.
Described film packing sheet adopts the nonmetallic materials of heat-resisting water or metal material or composite to make.
The beneficial effects of the utility model are: this high thermal conductivity cooling tower diaphragm type filler is compared with present cooling tower film filler, and heat transfer area increases, and conduct heat and all raisings greatly of mass tranfer coefficient, so thermal performance significantly improves.Air-flow fully contacts under the perturbation action of packing sheet corrugated with current, has reduced the adverse effect of fluid boundary layer to conducting heat, and has improved evaporation of water speed.After tested, under the condition of equal gas-water ratio, this its cooling capacity of high thermal conductivity cooling tower diaphragm type filler reaches two more than 140% of terraced ripple film filler of present routine, and its thermal performance promotes manyly under low spray density operating mode.Because this filler thermal performance is good, its design air flow can correspondingly reduce, and under the low spray density operating mode, its trickle section resistance will further descend, and filler resistance design load has bigger fall than conventional design.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of film packing sheet of the present utility model.
1. film packing sheets, 11. negative and positive junction surfaces among the figure
The specific embodiment
A kind of high thermal conductivity cooling tower diaphragm type filler, splice by as shown in Figure 1 film packing sheet 1 and to constitute, correspondence is provided with negative and positive junction surface 11 on each film packing sheet 1, adjacent two packing sheets engage by 11 intercalations of negative and positive junction surface, be formed with numerous folding ripples on each film packing sheet 1, the folding ripple is provided with the one's water breaks joint; Folding wave-wave face is made of numerous little cambered surfaces continuous, projection.
Be provided with slot between the adjacent films packing sheet 1, negative and positive junction surface 2 of each row formula that staggers distribute to be provided with on the film packing sheet 1, and film packing sheet 1 adopts the nonmetallic materials of heat-resisting water or metal material or composite to make.
In the utility model, formed numerous abutments by the negative and positive junction surface between the adjacent packing sheet, trickle will carry out secondary distribution by these abutments the time, improved the uniformity of water distribution effectively.The integrally-built steadiness after packing sheet is assembled into filling block has also been improved at the abutment that the formula that staggers on the packing sheet distributes simultaneously.Pitch of fins between the packing sheet designs greatlyyer, and is provided with slot between adjacent packing sheet, is guaranteeing to have reduced the flowing resistance of filler under the higher prerequisite of filler thermal performance.
When spray density is low, water droplet can form on the packing sheet surface constantly to roll and form the 3 D stereo moisture film, this moisture film is compared with the two-dimensional plane moisture film that conventional film filling surface forms, not only the time of staying of moisture film on filler is longer, and aqueous vapor can realize comprehensive abundant contact, reduced the adverse effect of fluid boundary layer to conducting heat, the heat of aqueous vapor, matter transmission strengthen.By on packing sheet folding ripple, the one's water breaks joint being set, when water is passed through in filler, can realize repeatedly redistributing, further improved the uniformity of water distribution.
The utility model makes the specific area of this filler increase about 25% than general two terraced ripple film fillers by improving the complexity of film packing sheet waviness of the surface.This film filler not only has good thermal performance under the operating mode of low spray density, its flowing resistance also can be well controlled, and is fit to very much the requirement of low power design.Because this filler thermal performance is good, its design air flow can correspondingly reduce, and under the low spray density operating mode, its trickle section resistance will further descend, and filler resistance design load has bigger fall than conventional design.
