(54) SHOWER WATER COOLERS

one

The invention relates to the field of power engineering, in particular, to devices for cooling discharged hot water in power plants and industrial enterprises.

A splash cooling device is known, which is installed both on the shore of the reservoir and above its water area. During the construction of the spray unit above the water area of the reservoir, the laying of pipelines is carried out on pile supports, and at greater depths or rocky bases the distribution pipelines are laid on floats.

Hot water is supplied to the water distribution piping system and under pressure is sprayed by nozzles-nozzles in the form of flares over the water surface of the reservoir 1.

However, the creation of such a device requires the presence of a certain place filled with communications, long-distance water lines.

The disadvantage of the splash water cooler is the uneven cooling of water as a result of exposure to flares.

splashing constantly changing wind currents.

It is also known spray cooling device containing mounted on the floats supporting frame, a pump and a water distributor connected to it.

 Water nozzles distributed in a channel in the form of nozzles-nozzles create large individual spray plumes with large droplets. Moving nozzles afloat allow you to adjust the heat transfer rate in different parts of channel 2.

The disadvantage of such a spray cooling device is insufficient cooling of hot water due to the inability to create small droplet flares, which are very susceptible to wind exposure and have in turn undesirable environmental effects in the form of friable and blown away small droplets and water vapor condensed. on various objects near the canal, and at negative air temperatures there may be icing of the territory and buildings located on it.

The purpose of the invention is to increase the intensity of cooling, reducing the loss of water from the moth.

To achieve this goal, the spray cooling device is equipped with a mesh casing and an inclined tray installed between the floats, and the water distributor is made in the form of irrigation nozzles installed in the casing.

FIG. 1 shows a spray cooling device, side view; in fig. 2 - the same longitudinal view; in fig. 3 - the same, top view.

The spray device contains floats 1 of the floating base, a metal support frame 2 to which the mesh case 3 is attached, and a bottom tray 4 is installed between the floats 1 and the water distributor 3, which is connected to the floor 5 connected to the pump 6, and made in the form of a multi-pipe system 7 with irrigation nozzles 8 placed on them. Pallet 5 has a slope for the flow of chilled water in one direction and thus prevents recirculation of the chilled water.

Hot water is taken by the pump from the bottom of pan 4 and is fed under pressure 5 to the multi-pipe system 7 to the irrigation nozzles 8, which create a small drop of hot water enclosed in the volume of the mesh casing 3. The droplet flow cooled by air flow falls into the sump 4 and the cooled water then drains from the sloping surface of the sump into the transit flow of the hot water and mixes with it. The mesh casing 3, made of finely meshed mesh, allows you to organize an air flow passing through the environment of the drip flow, while the fine mesh, having a water film on it, will function as a cooling tower tower.

Optimally placed sprinklers

water coolers in the zone of intense movement of hot water entering the cooler pond or natural reservoir can most effectively affect the concentrated

I ejection of hot water into these reservoirs due to the high cooling capacity of the spray cooling equipment, as well as protects the nearby territory from the moisture and droplet effects associated with wind entrainment.
