BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate assembly comprising a cooling tower, a cleaning device, and the like for purifying water. The cooling towers are supplied with hot water of a shorado cooling filler, which consists of a system of different shapes and configurations. The individual plates are assembled such that vertical channels are formed between them, through which air flows to cool the water. The water runs down the surface of the slab, forming a water film on them, where the heat exchange between water and air occurs and the water is cooled.

Plates made of different materials, straight or differently shaped, are used for cooling fillers. The reason for shaping is to create as large a surface as possible for the longest possible time for water to form on the membranes of the water membrane. There are other possibilities for intensifying the cooling process to create the maximum possible surface area and suitable molding. Another factor affecting the process of cooling is the resistance that the filler is flowing through the air, and thus affects its amount that is passed through the cooling tower.

One of the basic known designs of fillings consists of corrugated asbestos-cement slabs, which are usually embossed in the three apexes by support flanges by which the plate abuts the adjacent plate, the indent defining a mutual spacing. Although these fillings are simple, they have a very nice effect.

Other known fillers are formed by a set of vertical blankets provided with horizontal and oblique elongated projections designed to extend the runners and cause turbulence in the jet, but their effectiveness is also small.

In order to improve the contact of the water with the air stream of some known cooling towers, a simple corrugated plate arrangement, the surfaces of which are arranged at an angle of 45 ° to the vertical, but each plate is inclined in a direction other than adjacent so that their surfaces are. mutually fluent; in this solution, only a more favorable air flow is achieved, but the surface of the plates remains as in the basic solution. More progress has been made in corrugated sheet corrugations that are corrugated in two mutually oblique directions, wherein the one-dimensional wave size is substantially smaller than in the other direction. The distance of the plates is maintained by spacers which are threaded on the fasteners, or extrusions formed in plates. This second fill has a number of advantages, but still does not achieve the optimum effect in known systems.

The drawbacks of the hitherto known filler plates are removed by a set of filler panels according to the invention, solved for cooling towers or cleaning 206938

No. 206938 water purification apparatus comprising corrugated plates in two mutually perpendicular directions, the principle of which is to form two corrugated plate assemblies arranged alternately in abutment against each other, the two corrugated sheets being formed into waves whose curves are superimposed on each other the adjacent circular arcs oriented alternately to opposite sides, the surfaces of which are perpendicular to the flowing direction of the water and which extend into planar surfaces at the edges of the plates, and each even plate is formed in the shape of a barrel in the direction perpendicular to the wave and its alternately IV-shaped ribs are parallel to the direction of flow of water, the apex areas of the ribs being flattened, each rib having a trapezoidal profile, while the forming lines of each odd plate extend over its entire length, and the plates are provided with an elongated pattern. sections extending more level offset vertically. The formation of even plates in the shape of lomenons gives the required stiffness to the plates and creates channels for air flow in which minimal resistance is stored. The flattened apex forms the abutment surfaces that allow perfect connection with the odd plates. The vertical ripple of the plate increases their area and the gimbal changes the speed of movement of the water membrane, which at the same time changes its thickness, which also intensifies the cooling of the water. The corrugations pass on the lower and upper edge portions in a flat / flush surface that provides water to both sides. The longitudinal horizontal cuts in the odd walls cause the water membrane to interrupt, which in turn forms again from the lower edges of the cuts down, but in a different composition, which intensifies the process of transferring heat to the flowing air. odd plates in a planar surface to ensure water is fed to both sides of the plates. Exemplary embodiments of a plate assembly according to the invention are shown in the drawings, wherein Fig. 1 is a view of the first plate of the system; which is, for example, a plate of the entire panel, FIG. Fig. 2 is a cross-sectional view of the first plate taken along the line A-A in Fig. 1; 3 shows a longitudinal section through the first plate, taken along the plane B-B of FIG. 2, showing the detail of the corrugation of the first plate, FIG. 4 is a view of a second system board which can always be an odd board; FIG. 5 cross section SCOPE A system of panels of panels, in particular of cooling towers, consisting of corrugated plates, characterized in that they are formed by two kinds of plates (1, 6), parallel to each other, arranged one behind the other, both plates (1,6) being formed into waves whose curves (2) are planes parallel to the flow direction of the water. they are formed by circular arcs which adjoin one another and are alternately oriented on the second plate, taken along the plane C-C of FIG. 4, FIG. Fig. 6 is a sectional view of the second plate taken along the line D-D of Fig. 5; Fig. 7 is a cross-sectional view of Fig. 6 taken along the line D-D of Fig. 5; 8 is a perspective view of a portion of a cooling tower filler formed by a plurality of plates according to the invention. The cooling tower filler assembly 1, 6 comprises two kinds of plates arranged in parallel and alternately in succession. The first plate 1 of the system is corrugated, the forming curves 2 of the waves lying in planes parallel to the direction of flow of water and their surfaces are perpendicular to the direction (the flowing curves 2 being circular arches that are interconnected and alternately oriented to the opposite sides. In the direction perpendicular to the waves, the first plate 1 is formed into a fractured shape, where the ridges and valleys are flattened and the surfaces of the flattening are parallel to the median plane of the first plate 1, so that the first plate 1 is in the direction of flowing water is formed by a set of trapezoidal ribs 4 which are interconnected and oriented alternately on opposite sides, the short trapezoidal base 5 being relatively short, the second plate 6 of the system being also corrugated and forming the 2 wave curves also in planes parallel to each other the direction of flow of water, wherein the surfaces of the waves protrude along the entire length of the second plate 6 and the forming curves 2 of the waves are formed by circular arcs which adjoin one another and are alternately oriented on the opposite sides. Also, on the marginal areas of the plate 6, the corrugations pass into a planar surface 3 in order to improve the water transfer to both sides of the plates 1. The second plate 6 is provided with elongated cuts 7 extending perpendicular to the flow direction and spaced apart in the water flow direction so that overlap in this respect. By alternately assembling the first plates 1 and the second plates 6 in succession, a filler is formed to form a water membrane from the sprayed water. The channels formed in the system flow air drawn in from the outside, which cools the water membrane on the plates 1, 6. The first plates 1 or the stiff plates 6 can also be arranged one after the other, not alternately, depending on the use for a particular kind towers or cleaning equipment. However, the alternating arrangement is most preferred. the opposite sides, the surfaces of which are perpendicular to the flow of water, wherein the corrugations in the marginal areas pass into planar surfaces (3) and the first pads (1) are formed in the shape of a barrel shape and their successive and alternating on the opposite sides of the ribbed trapezoidal cross-section, the narrower bases have a flattened flattening of the ridges, wherein the second plates (6), the surfaces of which are longitudinally extending, are provided with a directional direction: water flow and mutually offset longitudinal slots ( 7) running perpendicularly in the vertical direction. 8 drawings
