Abstract

The invention relates to a power system, namely to devices for cooling water in a cooling tower. The invention makes it possible to increase the efficiency of heat and mass transfer by turbulizing the flows of heat exchanging media. The cooling tower sprinkler contains a block of vertical pipes 1 with helical inserts 2 in the upper part. Inserts 2 are made in the form of two blades with inclined grooves 4, by means of which liquid is withdrawn into the annular gap 3 between the pipes 1 and the inserts 2 and flows down in the form of a film, interacting with the ascending air flow. 3 il.sl (rig, 2

Description

The invention relates to a power system, namely to devices for cooling water in a cooling tower.

A cooling tower irrigator is known that contains bluck corrugated sheets in contact with the protrusions and flat sheets disposed between them.

The disadvantage of such an irrigator is the low efficiency of water cooling due to leakage of water jets in open vertical channels.

Known irrigation sprinkler containing a block of corrugated sheets installed rusami, separated from each other.

The main disadvantage of such an irrigator is also the low efficiency of water cooling due to leakage of jets and water droplets in the channels without colliding with the walls.

The closest in technical essence and the achieved effect is a cooling tower irrigator containing a block of vertical pipes.

The main disadvantage of the known irrigator is the insufficiently high efficiency of heat and mass transfer due to the presence of smooth unperturbed films of flowing water interacting with air on only one surface.

The purpose of the invention is to increase the efficiency of heat and mass transfer by turbulent flow of heat exchanging media.

This goal is achieved by the fact that the cooling tower irrigator, containing a block of vertical pipes, is additionally equipped with helical inserts placed in the upper part of the pipes with an annular gap and made in the form of mainly two blades, on the upper surfaces of which inclined grooves are made.

FIG. 1 shows a block of vertical labor irrigators, a general view; in fig. 2 - pipe sprinkler on a screw insert; in fig. 3 - block, top view.

The sprinkler of the cooling tower contains a block of vertical pipes 1 with helical inserts 2 placed in the upper part, made in the form of two blades. The pipes 1 may be formed by a series of corrugated sheets in contact with each other. The inserts 2 are placed in pipes 1 with an annular gap 3. On the upper surfaces of the inserts 2, inclined grooves 4 are made. The blocks of pipes 1 can be installed in several lines.

The cooled liquid is sprayed over the fill. Drops and trickles of liquid fall on the walls of pipes 1, on screw-shaped inserts 2. With the help of grooves 4, the liquid is withdrawn into the gap 3, falls on the walls of pipes 1, which ensures the presence of a continuous film of flowing liquid. The air, thanks to the screw-shaped inserts, is twisted, additionally turbulent.
