Abstract

The invention relates to a power system and m. Used in circulating water cooling devices. The purpose of the invention is to provide effective cooling of polluted water. The sprinkler contains grids (P), installed in a row on suspension 6. R-ribs 9 of stiffness are placed, and parallel to one of them with a uniform pitch are jumpers 7 alternating with gaps 8. One of the jumpers closest to the rib is set AA twice as long as a friend. The jumpers P of the adjacent channels can be installed perpendicularly or in parallel with one displaced relative to the other. The stiffeners can be extended with increasing height to the center and provided with vertical plates 14 installed under them. The water to be cooled is sprayed onto the sprinkler. Striking the surface of the jumpers and stiffeners P of the upper tier, the droplets are crushed, fall on the lintels and the edges of the next tusk, etc., subjected to repeated crushing and mixing. The cooling air enters the sprinkler from below and passes through an even flow through the gaps between the bridges. The overlap of the gaps provides intensive turbulization, which is facilitated by oscillations of P on a flexible suspension. As a result, the contamination from the surfaces P is reduced and the water is effectively cooled. 3 hp f-ly, 3 ill. SL

Description

The invention relates to a power system, namely to devices for cooling the circulating water.

The purpose of the invention is to provide efficient cooling of polluted water.

FIG. one.

The cooling tower sprinkler contains horizontal | 5 horizontal grids 1, having a rectangular shape in plan, fixed with bits 2-5 on suspension 6. Grids are provided with bridges 7 alternating with uniform pitch, with gaps 8. 20 diagonal m of the grid are made with fins 9 and 10 stiffness curvilinear convex shape. Jumpers are located parallel to one of the edges (for example, rib 10), with one of the closest 25 to rib 10 of jumpers 11 being installed from it at a distance Z that is twice as large as the distance from rib 10 to jumper 12 located with the other

The suspension 6 is made in the form of a vertical flexible cable passing through the center 13 of the intersection of the stiffeners, the gratings being attached to the suspension 6 with the possibility of rotation about the axis 180. In this case, the lattices of adjacent Rus 2 and 3 (or 3 and 4, etc.) are set so that the jumpers 7 in them are parallel, but displaced relative to each other by the distance Q

1, i.e. in adjacent rusa jumpers overlap the slits of the grids. This achieves a more complete interception of the stream of falling water.

With insufficient air flow pumping through the sprinkler, the gratings of each successive Rus are 3 or 5 relative to the previous one, i.e. Russ 2 or 4, fixed on the suspension 6 with a turn of 90. In this case, the bridges in the grids of adjacent Rus are located mutually perpendicularly (not shown), as a result of which the aerodynamic drag of the irrigators becomes smaller than with the parallel arrangement of the bridges.

The stiffening ribs 9 and 10 are made of variable height, increasing to

the center 13 of their intersection, and is equipped with water flow jets in the form of vertical plates 14, attached to the side of these ribs.

Sprinkler cooling tower works as follows.

The water to be cooled is sprayed onto the sprinkler. Hit the surface of the jumpers 7 and the ribs 9 and. 10 stiffness grating 1 of the upper tier 2, the spray splits into droplets that fall on the lintels 7 and the ribs 9 and 10 stiffness of the grids 1 of the underlying tars 3-5, subjected to multiple crushing and mixing.

Falling water droplets are exposed to the air supplied from below, which passes (due to the absence of stagnant zones) by an even flow through the slits 8 between the bars 7.

The overlapping of the gaps by bridges in the irrigator provides for intensive turbulization of heat-exchanging media. The suspension 6 of the grids, implemented in the form of a vertical flexible cable passing through their center 13 (center of gravity), contributes to oscillations with a small amplitude (vibration) of all the grids under the hydrodynamic effect of a falling stream of water and oncoming airflow. This further intensifies the turbulization of these streams, ensures the washing off of contaminants from the surface of the grids and the effective cooling of polluted water.
