The invention relates to the field of recycling water supply, namely the structural elements of the towers and other apparatus for heat and mass transfer between liquid and gaseous media, in particular to elements sprinklers and vodoulaviteli cooling towers.
Known unit of cooling tower fill, consisting of vertical corrugated sheets with cut corrugations that when the bond between them form a vertical tube-like channels (RF patent No. 2300067, MKI F28F 25/08, 27.05.2007).
Also known sprinklers from polymeric materials, such as irrigation device made in the form of a block of plastic pipes (see, for example, patent RF №2141616, MKI F28F 25/00, 20.11 1999; RF patent №2141617, MKI F28F 25/08, 20.11.1999).
The common disadvantage of these structures is their high aerodynamic resistance and uneven cooling of the water area of the tower, due to the closedness of the tubular channels of sprinklers.
A known design of leaves of cooling tower fill, containing corrugations in the form of continuous waves, located at an angle to the edge of the sheet (the United Kingdom patent No. 1177124, F28C 3/00, 1970; U.S. patent No. 4668443, NCI 261-1123, 1987; RF patent №2001375, MKI F28F 25/08, 1993).
A common disadvantage of these constructions sheets of the fill, as practice shows operation is the emergence and the persistence of the jet stream of fluid in which Madinah bumps, which reduces the intensity of heat and mass transfer.
A known design of leaves of cooling tower fill, containing sinusoidal corrugations located at the height of the sheet in the form of two or more sections, inclined in one direction from the vertical (RF patent No. 2222758, MKI F28F 25/08, 27.01.2004; RF patent №2257521, MKI F28F 25/08, 27.07.2005).
The presence of warped flute, and with an inclination in one direction from the vertical, reduces the transit time of water on the tile height of the fill, and thus reduces the efficiency of heat exchange.
A known design of sheet fill containing sinusoidal corrugations underneath opposite angles to the edge of the sheet (patent RF №2109242, MKI F28F 25/08, 20.04.1998; RF patent №2306519, MKI F28F 25/08, 20.09.2007).
The main disadvantage of the data sheets of the fill is of considerable length of inclined sections that triggers a jet stream of water in the troughs of the corrugation.
Closest to the invention to the technical essence and the achieved result is a list of cooling tower fill, containing sinusoidal corrugations located at the height of the sheet in the form of two or more sections with opposite angles of inclination to the horizontal, and with decreasing values of these angles on the sections from the bottom up while maintaining the height and width of the corrugations, the corners at the tops and bottoms are reduced (parenth No. 2217676, MCI F28F 25/08, 27.11.2003). The invention adopted for the prototype.
The above-described execution of the sheet of the fill has certain disadvantages, namely, the reduction of the flow area of the channels and sharp bends of short channels on the height of the sheet, which increases the aerodynamic resistance of the fill. The reduction of the angles of inclination relative to the horizontal short channels leads to a substantial lengthening, which provokes the appearance of the jet stream, which also leads to reduction in the efficiency of heat exchange.
The invention solves the problem of increasing the efficiency of the cooling water in the cooling tower fill by increasing the specific interfacial surface, respectively, and the contact time of the phases.
To achieve this technical result sheet fill herringbone patterns, made of a polymeric material, such as PVC, contains corrugations in the form of continuous waves, with each corrugation is made in the form of a zigzag sequence of equal length and cross-section of short channels, which are oriented to each other at the same angle not less than 90° and less than 180°, and the ratio of the height of the corrugations to the edge length of a short channel-zag guide is at least 2, 5.
Known irrigation device made in the form of vertical blocks or under what aklanon to the vertical plastic tubes of various shapes in cross section (Gladkov, VA, Kucherenko DI water Recycling. (Water cooling system). - Moscow: stroiizdat, 1980; RF patent №2309356, MKI F28F 25/08, 27.10.2007; RF patent №2317502, MKI F28F 25/08, 20.02.2008).
The disadvantage of this type of blocks sprinklers are negligible specific interfacial surface and a short contact time of the phases and, as a consequence, the low efficiency of the heat transfer.
Known blocks of sprinklers, composed of sheets of rectilinear corrugations having a cross-sectional view of a continuous wave and along the vertical edges (RF patent No. 2300067, MKI F28F 25/08, 27.05.2007) or at an angle thereto (patent RF №2043600, MKI F28F 25/08, 10.09.1995; RF patent №2133427,MKI F28F 25/08, 20.07.1999).
The famous tower fill, consisting of blocks arranged in packages from installed vertically corrugated sheets arranged at an angle to the edges of the sheet parallel corrugations, each corrugated sheet contains two groups of parallel corrugations, converging in the middle of the sheet, the corrugations of the left half of the sheet is bent to the right from the vertical corrugations of the right half of the sheet is inclined to the left from the vertical, and collected in the package corrugated sheets form in the cross section of the diamond-shaped channels(RF patent No. 2306519, MKI F28F 25/08, 20.09.2007).
The main disadvantage of the fill is of considerable length channels that triggers strain the th flow of water in the troughs of the corrugation.
More effective from the standpoint of heat and mass transfer, are blocks of sprinklers in which the corrugations of adjacent sheets are angled to each other (patent RF №2008607, MKI F28F 25/08, 28.02.1994; RF patent №2122696, MKI F28F 25/08, 27.11.1998; RF patent №2132032,MKI F28F 25/08, 20.06.1999; RF patent №2145699, MKI F28F 25/08, 20.02.2000).
From above together last peer groups closest to the invention to the technical essence and the achieved result is a cooling tower fill, containing sheets with corrugations in the form of continuous waves, which are in contact with each other along the crests of the corrugation with the formation of channels along the height of the fill, while the corrugations are made at an angle to the edges of the sheets, the corrugations of adjacent sheets can be oriented in the same direction and at an angle to each other (patent RF №2132032,MKI F28F 25/08, 20.06.1999).
A common shortcoming of this type of blocks of sprinklers is the existence of the jet stream of the liquid in the troughs of the corrugation, which reduces the intensity of heat and mass transfer, as the basis unit of the fill is formed from corrugated sheets forming the assembled block the channels of different forms, but all with a straight guide.
The objective of the invention is to increase the efficiency of the heat transfer and the rigidity of the block of the fill.
Under the first scenario execution unit technical result dostigaetsya, in block fill, with alternating vertical flat and corrugated sheets of fill herringbone patterns, made of a polymeric material, for example PVC, and interconnected by means of connecting tubes, the unit contains many sheets of fill herringbone patterns, each corrugated sheet herringbone patterns on the zigzag lines of the ribs in contact with the flat sheet forming identical zigzag channels in a block height of the nozzle and is connected to one of the flat sheets of rigid connection, for example by welding.
According to the second variant the execution of the technical result is achieved by the fact that in the block fill even corrugated sheets fill herringbone patterns rotated around a horizontal axis by 180° relative to the odd corrugated sheets to fill herringbone patterns.
According to the third variant of execution of the technical result is achieved by the fact that in the block of the fill sheets are mounted so that they have a point contact with each other at points where the zigzag edges and each zigzag edge and form an end-to-end in vertical and horizontal directions cross zigzag channels, and the connecting tubes are installed in areas of point contact on zigzag is Abram corrugated sheets to fill herringbone patterns.
The claimed invention is illustrated in the drawings, where figure 1 shows a General view of sheet fill herringbone patterns, figure 2 - General view of the block of the fill according to the first embodiment, figure 3 - General view of the block of the fill according to the second embodiment, figure 4 - General view of the block of the fill by the third variant of execution.
Figure 1 - 4 digits indicated the following positions: 1 - sheet of the fill herringbone patterns, 2 - zigzag corrugation, 3 - short channel, 4 - flat sheet, 5 - zigzag channel, 6 - zigzag edges of the sheet 7 - connecting tube.
Sheet 1 (Fig 1) fill herringbone structure is a solid structure and contains corrugations 2 in the form of continuous waves from one edge of the sheet to the other. Each corrugation 2 made in the form of zig-zag sequence of equal length and cross-section of short channels 3, oriented to each other at equal angles. Such mutual angular position of the short channels 3 and determines the structure of the sheet fill - herringbone structure. The sheets 1 are collected in a vertical position in the block with the formation of multiple zigzag channels. Using worksheet 1 fill herringbone patterns may be run several variants of the block cooling tower fill.
Block fill in the first embodiment perform contains many of Vertica is Ino installed and striped sheets 1 herringbone patterns and flat sheets 4 with the formation of identical zigzag channels 5 at the height of the block of the fill (figure 2).
Block fill on the second version of the runtime also contains a number of vertically installed and striped sheets 1 herringbone patterns and flat sheets 4 with the formation of identical zigzag channels 5 at the height of the block fill, but even corrugated sheets fill herringbone patterns rotated around a horizontal axis by 180° relative to the odd corrugated sheets to fill herringbone patterns (figure 3).
In the first and second versions of the blocks of each corrugated sheet 1 fill herringbone patterns is connected to one contact with him flat sheet 4 rigid connection, for example by welding, for all zigzag edges 6. The whole set of corrugated sheets 1 and flat sheets 4 included in the block is tightened between a connecting tube 7.
Block fill by the third variant of execution contains only leaves 1 herringbone patterns that are rotated relative to each other by 180° and installed so that they have a point contact with each other at points where the zigzag edges 6 and each zigzag edge 6 and thus form an end-to-end in vertical and horizontal directions cross zigzag channels 5 and the connecting tube 7 is installed in areas of point contact at zigzag edges of corrugated l the ists fill herringbone patterns (figure 4).
Block fill, composed of sheets 1 herringbone patterns, works as follows. The cooled water is evenly distributed over the surface of the sheets 1 unit of cooling tower fill, drains vertically under the action of gravity along the walls zigzag corrugations 2. Due to the presence of short channel 3, is constantly changing its direction, is considerably longer distance for the passage of water, and changes the movement direction vector of the cooling air, which causes further turbulence in the flowing film of water on the zigzag channels 5, which eventually increases the efficiency of heat exchange. The unit, made by the third variant, due to the presence of cross-zigzag channels 5 allows to obtain more uniform distribution of cooling water over the entire area of the sheets 1. Restrictions imposed by the angle of convergence of short channels and the ratio of the height of the corrugations to the edge length of a short channel-zag guide to reduce wind resistance blocks of the fill. Flat sheets 4, used for the first and second embodiments of block fill, provide additional rigidity of the blocks.
Thus, the use of the invention allows to improve an important technological and operational parameters of the fill: first, p is increase the amount of cooling water, secondly, to reduce aerodynamic drag and, thirdly, to increase the rigidity of the structure, and hence its durability.

Proposed packing is made by hot casting in form of corrugated lattice-type structure in form of parallelogram in plan whose longer sides have length of 300-1800 mm and shorter sides have length of 150-1500 mm. Section of fibers of packing has form of polygonal geometric figure, circle or tear-shaped figure at area of 0.5-50 mm2; intersection of fibers forms meshes in form of parallelogram at area of 25-2500 mm2. Corrugation pitch is equal to 20-100 mm and angle of inclination of corrugations relative to longer sides of packing is equal to 20-90°. Besides that, section of corrugations has form of acute-angled zigzag figure or zigzag trapezoidal figure at corrugation height of 20-90 mm. Shorter sides made in form of stiffeners have three holes each, 5-20 mm in diameter made along central vertical axis symmetrically relative to horizontal central axis of packing.
EFFECT: reduction of aerodynamic drag of packing; enhanced efficiency of heat- and mass-exchange.

SUBSTANCE: the invention may be used as the constituent heat-mass-exchange equipment at the direct contact between the gas and the liquid, in particular, in the industrial water cooling towers for cooling the circulating water. The water-cooling tower sprinkling device is made in the form of the module out of the layers of the polymeric mesh shells made cylindrical and arranged in all the horizontal layers in parallel to each other and welded on the ends of the module among themselves in the places of their touch. At that each mesh shell additionally contains in its volume the vane swirlers representing the polymeric cylinders, on the internal side of which there are vanes. Besides the vane swirlers may be rigidly fixed in the volume of the mesh shell by the welding or fixers. The invention solves the problem to increase effectiveness of the heat-mass exchange process.
EFFECT: the invention ensures the increased effectiveness of the heat-mass exchange process.
