Abstract
Provided is a filler material for cooling towers, said filler material comprising a plurality of filler sheets layered together, each filler sheet having a plurality of protrusions. The filler material is disposed inside a cooling tower. In between the layers, source water is supplied from above and ambient air is supplied from the side, thereby bringing the source water in contact with ambient air and cooling said water. At least some of the plurality of protrusions are flattened protrusions, shaped like flattened circular truncated cones elongated in the direction of ambient air flow; this increases the force with which the source water supplied from above hits the protrusions, compared to the low force with which the ambient air hits said protrusions. Furthermore, since each flattened protrusion is a circular truncated cone and has no corners at either end in the long direction, less pressure is lost than would be with protrusions having corners. Consequently, the dwell time of the source water is increased despite the comparatively low loss of pressure, increasing droplet effects.

Summary of the invention
Invent technical problem to be solved
Yet; For above-mentioned existing packing material; If packing material is increased with the number of the jut of sheet material; Then can occur aperture opening ratio (from the direction of packing material with the surperficial quadrature of sheet material, the ratio of the mirror plate in the whole area) step-down, crushing from extraneous air to interlayer that supply with increases such problem.On the other hand, if the number of jut is reduced, following such problem then can occur: though aperture opening ratio increases, crushing reduces, and the collision of former water and jut correspondingly reduces, and then heat exchanger effectiveness reduces.
So the present invention is point in view of the above problems, although with the packing material that the still excellent used for cooling tower packing material of the less heat exchanger effectiveness of crushing is provided and constitutes this packing material with sheet material as problem.
In order to solve above-mentioned problem; The present invention provides a kind of used for cooling tower packing material; Said used for cooling tower packing material constitutes with sheet material through range upon range of many packing materials with a plurality of juts; And be configured in the cooling tower, interlayer from above supply with former water and supply with extraneous air from the side, cool off thereby former water is contacted with extraneous air; It is characterized in that at least a portion in said a plurality of juts is to form the externally flat jut of the flat truncated cone shape of the flow direction length of air.
In such structure, flat jut is along the long flat of the flow direction of extraneous air, and from this point, though the degree of extraneous air bump is little, the amount of the former water bump of supplying with from the top increases.And flat jut is a truncated cone shape, does not have the angle at the both ends of length direction, thereby compares with the situation with angle, can reduce crushing.Therefore, although crushing is fewer, but still can prolong holdup time of former water, and can increase spittle effect.
Said a plurality of jut can at least a portion be the flat jut along the truncated cone shape of the long flat of flow of external air direction both, also can be that the whole of a plurality of juts are the truncated cone shape that form along the long flat of the flow direction of extraneous air.
Though packing material with the surface of sheet material on the former water that flows down of stratiform can with the extraneous air heat exchange; But, usually in the former shipwreck of the downside of jut to flow, especially if the jut of flat; The immobilising area of then former water is bigger, and rate of heat exchange can descend.Yet in the present invention, flat jut forms truncated cone shape; Therefore; Wander flat jut above the flat jut in former water one edge above flow down to top-direction from the bottom of flat jut, Yi Bian any circuitous following side to flat jut of curved surface at both ends along its length, circuitous former water conservancy to following side is with its surface tension of holding; Flow down to bottom direction from the top along following side surface, also can flow down to the downside of flat jut.Thereby, do not worry that the downside that former water does not flow to jut causes rate of heat exchange to descend yet.
In the present invention; Preferably constitute: said flat jut is configured to become row and form many row's this row at above-below direction along the direction of flow of external air, and at least a portion quilt of said a plurality of flat juts disposes under last row's flat jut vertical with staggering.
According to this used for cooling tower packing material, the part of former water deviates from the surface of packing material sheet material becomes the situation that water droplet falls, and the droplets impact its that does not strike certain section flat jut increases to the probability of the flat jut of next section of this section.That is, strike the flat jut of next section and to become the probability that fine water droplets disperses then high, utilize spittle effect, can obtain excellent more rate of heat exchange.
In the present invention, preferably constitute: said flat jut is provided with ribs along projected direction.Because flat jut is flat, thereby compare with jut such as circle, easily to a direction bending, if but along projected direction ribs is set as stated, just can reduce the flat jut possibility of bending accidentally.
In the present invention; Preferably constitute: each packing material has a plurality of recesses with sheet material; This recess forms the externally long flat truncated cone shape of flow direction of air; A plurality of juts constitute: extend at the packing material of a side adjacency of stacked direction and use sheet material, and the leading section of a plurality of each jut is fitted to the packing material that the is formed on adjacency recess with sheet material, thereby keep the interlayer interval of packing material with sheet material; In the part midway of the length direction of said each recess, the recess of the direction of intersecting with this length direction is formed on the outstanding side surface of each packing material with the recess of sheet material with ribs.
The recess that is utilized in the direction that the part midway of the length direction of each recess intersects with this length direction is formed on the formation of each packing material with the outstanding side surface of the recess of sheet material with ribs; Even the leading section of the jut of flat and recess are chimeric each other; Through the support of recess, can make the chimerism stabilisation of jut and recess with ribs.
In the present invention, preferred following such formation: at the leading section and the chimeric state of a plurality of recess of a plurality of juts, the length direction counterpart of said leading section and recess utilizes recess chimeric with the elasticity of ribs.Insert if recess is enlarged ground by the leading section of jut, then recess is close to the length direction considerable part of jut and recess with the elasticity of ribs each other, thus mosaic process portion and recess reliably.In other words, if the length direction considerable part of jut and recess is chimeric each other, then recess is with by the mode strain that enlarged; Recess supports this strain with ribs; And then apply elastic restoring force to recess, through this elastic restoring force, jut and recess are chimeric reliably.
In the present invention; Preferred following formation: on the whole surface of each packing material with sheet material; Be formed with and be used to contact the concavo-convex wave portion that former water increases the surface area of this former water; And recess forms at the height of stacked direction with ribs and is no more than the height of concavo-convex wave portion on stacked direction.Constitute according to this, can guarantee based on recess, and form the height that is no more than concavo-convex wave portion, thereby correspondingly can seriously not hinder the flowability of extraneous air with the flexible jut of ribs and the chimeric support force of recess.
In addition, the present invention provides a kind of said packing material to use sheet material, it is characterized in that, constitutes above-mentioned any used for cooling tower packing material through range upon range of.That is, use sheet material for the packing material with a plurality of juts that constitutes used for cooling tower packing material of the present invention, at least a portion of said jut forms along the flat jut of the truncated cone shape of the long flat of a direction.
The invention effect
In the present invention, flat jut is along the long flat of the flow direction of extraneous air, from this point; Though the degree of extraneous air bump is little, the amount of the former water bump of supplying with from the top increases, and; Flat jut is a truncated cone shape; Both ends at length direction do not have the angle, thereby compare with the situation with angle, can reduce crushing.Thereby, although crushing is less, but still can prolong holdup time of former water, and spittle effect is increased, and then can provide rate of heat exchange excellent used for cooling tower packing material and packing material to use sheet material.

Next, with reference to Fig. 1, Fig. 7 to Figure 16 second embodiment of the present invention is described.Same with situation about explaining in the first embodiment; This used for cooling tower that is filled with the used for cooling tower packing material is in the cooling former water such as cooling water that quilt is heated and discharged in shop equipment etc.; For the component part of the cooling tower of explaining in the first embodiment, omit its explanation.The formation that the formation of second embodiment is different with first embodiment is that used for cooling tower packing material 1 and the packing material through this packing material 1 of range upon range of formation are with sheet material 5.
To shown in Figure 9, used for cooling tower packing material 1 constitutes with sheet material 5 through range upon range of many packing materials with a plurality of juts 15 and recess 20 like Fig. 7.In used for cooling tower packing material 1,,, make former water A and extraneous air B can be fed into interlayer through forming this space by forming the space with a plurality of juts 15 of sheet material 5 and recess 20 at interlayer along range upon range of each packing material of fore-and-aft direction.
Because each packing material is same formations with sheet material 5, thereby only a packing material is explained its formations with sheet material 5.In this case, be that the packing material that face side is observed describes with sheet material 5 to direction from Fig. 1.Like Fig. 7 and shown in Figure 8, packing material uses sheet material 5 as tabular and form the front and see it is rectangle (also comprising square) or parallelogram (acute angle angle and be generally below above 90 degree of 75 degree), and this point is identical with first embodiment.
In addition, packing material is formed by synthetic resin with sheet material 5, and pressure forming through having used metal die etc. is formed by a thin slice.Its size is restriction especially not, bottom surface length and highly can being set at respectively about 400mm～1000mm, and in addition, its thickness (thickness that is equivalent in this case, fore-and-aft direction) is generally about 0.2mm～0.7mm., can be enumerated as with sheet material 5 employed synthetic resin as packing material, PVC-U, polypropylene etc., this point is identical with first embodiment.
For packing material is increased with the surface area of sheet material 5, be formed with the undulatory concavo-convex wave portion 8 of fore-and-aft direction fluctuation in its roughly whole zone.In Fig. 9, only illustrate the part of concavo-convex wave portion 8.The crestal line 8a and the valley line 8b of concavo-convex wave portion 8 are parallel to each other, and form with the mode of crawling at the above-below direction zigzag.In addition, the degree of depth of concavo-convex wave portion 8 is the not special restriction of the degree of depth between the summit 81b of end face 81a and valley line 8b of crestal line 8a, can be for about 3mm～10mm, and this point and first embodiment are same.In addition, end face 81a forms vertical plane.
Being formed at packing material fitly disposes with above-below direction, left and right directions mode alternate with each other with jut of sheet material 5 15 and recess 20 each other.But, adjacent packing material with sheet material 5 each other in, jut 15 is formed on corresponding position with recess 20.In addition, in the zone that disposes jut 15 and recess 20, be not formed with concavo-convex wave portion 8.
Each jut 15 is identical formations, thereby only the formation of a jut 15 is described.Detailed formation at jut shown in Figure 10 to Figure 12 15.Shown in these figure, jut 15 forms from outstanding to the rear as the stacked direction side with the back of the one side of sheet material 5 as packing material.Jut 15 extends to this packing material with other packing materials of the rear adjacency of sheet material 5 with sheet material 5.
Leading section 17 is formed on the rear portion of trunk 16.Leading section 17 has front end main part 18 and the insertion section 19 that is formed on the rear portion of front end main part 18.Front end main part 18 forms more rearward, and left and right sides width narrows down gradually, highly becomes short up and down.Insertion section 19 forms and connects more rearward that left and right sides width narrows down gradually, highly become short up and down.Trunk 16 is different with the angle of inclination on the surface of front end main part 18.That is, the surficial inclination of trunk 16 is than the surficial inclination steep (greatly) of front end main part 18.Constitute through this, the surface of front end main part 18 is connected with the obtuse angle mode with the surface of trunk 16.
On jut 15 with below be formed with two groove 15a that separate at left and right directions.Through this structure, sectional area increases, and then has formed the formation that makes the corresponding raising of intensity.A packing material is formed with the jut 15 of a plurality of above-mentioned formations with sheet material 5.
Each recess 20 is identical formation, thereby only the formation of a recess 20 is described.Figure 13 to Figure 16 illustrates the detailed formation of recess 20.Shown in these figure, recess 20 forms from rearward caving in the front of the another side of sheet material 5 as packing material.Thereby packing material is formed with the shape for lugs part corresponding with the shape of recess 20 with the back of sheet material 5.The inner space of recess 20 is formed with the shape of the leading section 17 that can insert jut 15.That is, recess 20 forms in the truncated cone shape that is flat as the left and right directions length of flow of external air direction and at above-below direction.
But the inner face left and right sides width L6 of recess 20 forms greatlyyer than the left and right sides width L7 of the leading section 17 of jut 15, and the inner face height H 1 of recess 20 equates with the height H 2 of leading section 17 or forms lowlyer than H2, thereby recess 20 forms interference fit with leading section 17.The front and back depth D 1 of recess 20 forms greatlyyer slightly than the front and back length D2 of leading section 17.
In the back (be equivalent to outstanding side surface) of packing material, be formed with recess with ribs 21 with recess 20 corresponding regulation positions with sheet material 5.The mode that recess extends with the direction that ribs 21 intersects with the left and right directions (length direction) of edge and this face is formed at because of forming the rearward outstanding raised face 22 of recess 20.Recess is respectively formed at the upper and lower of raised face 22 with ribs 21.Recess forms with ribs 21 as follows: viewed forms the general triangular shape, is no more than the end face 81a of concavo-convex wave portion 8 at the back from its anterior and posterior height D3 of counting.In this case, recess forms consistent with the end face 81a of concavo-convex wave portion 8 with the anterior and posterior height D3 of ribs 21.
Be formed with the mode at the regulation position of sheet material 5 and insert through hole 25 to be dispersed in each packing material.Each inserts through hole 25 and is formed on each packing material with same position in the sheet material 5.Be used to make packing material respectively to insert through hole 25 with support column 26 insertions and the perforation of sheet material 5 range upon range of state stabilisation each other.The position configuration of each patchhole 25 is following position: when support column 26 being inserted and connect this patchhole 25, adjacent packing material is aimed at fore-and-aft direction with sheet material 5 jut 15 each other and recess 20 before and after making.
The range upon range of packing material of fore-and-aft direction with sheet material 5 situation each other under, make a plurality of support columns 26 insert and connect and be formed on the insertion through hole 25 of packing material with sheet material 5, the packing material of range upon range of required number is with sheet material 5 then.At this moment, the packing material that fore-and-aft direction (stacked direction) is adjacent can be embedded in the recess 20 of the packing material of rear side with sheet material 5 with the jut 15 of sheet material 5 with the packing material of front side because jut 15 is formed on corresponding position with recess 20 each other with sheet material 5.
Because the inner face height H 1 of recess 20 forms lowlyer than the height H 2 of leading section 17, thereby in mosaic process portion 15 during with recess 20, recess 20 is strutted along the vertical direction a little on one side, Yi Bian by jut 15 insertions.In addition, because the leading section 17 of jut 15 forms truncated cone shape, thereby can be inserted into recess 2 easily.
And; Be formed with recess with strengthen rein in 21 with recess 20 corresponding regulation positions at packing material in the back of sheet material 5; Because of forming the rearward outstanding raised face 22 of recess 20, recess forms the direction extension that the left and right directions of edge and this face intersects with ribs 21.Therefore; Recess bears recess 20 by the power on the direction that struts with ribs 21, on the contrary, applies its elastic restoring force from recess with 21 pairs of juts 15 of ribs; And then can carry out the chimeric of jut 15 and recess 20 reliably, make jut 15 be difficult to extract from recess 20.In addition, also be formed with ribs (in this embodiment, two groove 15a) at jut 15, thereby can be suppressed at jut 15 chimeric with recess 20 time, leading section 17 bendings of jut 15.And, can also be suppressed at jut 15 and recess 20 when chimeric, leading section main body 18 top and followingly be out of shape to the inside.Therefore, can carry out the chimeric of jut 15 and recess 20 reliably.
Inserts has a plurality of juts 15 and recess 20 respectively with sheet material 5, thereby makes in sheet material 5 each jut 15 and recess 20 chimeric at the packing material of fore-and-aft direction laminated.Through making jut 15 and recess 20 many places chimeric, thereby make packing material become reliable with the hold mode between the sheet material 5.
In this used for cooling tower packing material of forming with sheet material 5 by a plurality of packing materials 1; Because it is the long flat of flow direction of externally air B that packing material uses the jut 15 of sheet material 5; Thereby compare with the degree of extraneous air B bump, it is many that the bump of the former water A that supplies with from the top becomes.And jut 15 is truncated cone shape, does not have the angle at the both ends of length direction, thereby compares with the situation with angle, can reduce crushing.Thereby, although crushing is less, still can prolong the holdup time of former water A, spittle effect is increased.
Owing to be formed with concavo-convex wave portion 8 at packing material with the surface of sheet material 5, thereby can make, and then can make former water A and extraneous air B carry out heat exchange efficiently along the surface area increase of packing material with the mobile former water A in the surface of sheet material 5.In addition, concavo-convex wave portion 8 form crestal line 8a and valley line 8b from above crawl when moving downwards, thereby can prolong from the top holdup time of the former water A that flows along valley line 8b downwards, and then can make former water A be cooled to more low temperature.
And recess forms the end face 81a that is no more than concavo-convex wave portion 8 with the anterior and posterior height D3 of ribs 21, and recess forms consistent with the end face 81a of concavo-convex wave portion 8 with the anterior and posterior height D3 of ribs 21.Therefore; Recess 20 can be guaranteed the sufficient elasticity restoring force, and then can prevent reliably that jut 15 from extracting from recess 20, though be provided with recess with ribs 21 simultaneously; But can not hinder the flowability of extraneous air B, thereby can suppress the rate of heat exchange decline of former water A and extraneous air B.
Because the top of concavo-convex wave portion 8 forms plane (end face 81a); Thereby the impedance of flowing to extraneous air B is reduced; And then extraneous air B is flowed smoothly, and only make the top form the plane, thereby the states that former water A edge concavo-convex wave portion 8 is flowed change.
Recess is not limited to above-mentioned each embodiment with the shape of ribs 21, need only flowing of not serious obstruction extraneous air B, and enough its elastic restoring force original position supporting projections portions 15 of ability is just passable.In addition, as long as recess uses the height D3 of ribs 21 for being no more than end face 81a, and is the height of enough its elastic restoring force original position supporting projections portions 15 of ability, then also can be inconsistent with end face 81a.Jut 15 top with below be formed with two groove 15a, but be not limited thereto, also can form one.In addition, can be not groove, but make it to reverse outstanding shape (shape) to the outstanding mountain of face side.When forming chevron, owing to need to embed in the recess 20, thereby at this moment, the height H 2 of leading section 17 is the values that comprised the height of the chevron that is formed at leading section 17.
