Description

The utility model relates to the field of circulating water supply, namely to the structural elements of cooling towers and other apparatus for heat and mass transfer between liquid and gaseous media.

Block sprinklers made of polymeric materials are known, for example irrigation devices made in the form of a block of plastic horizontal pipes (see, for example, patent RU No. , 11/20/1999).

These sprinklers are efficient and water resistant. However, these sprinklers have a relatively high aerodynamic resistance and, in addition, the disadvantage of these sprinklers is the difficulty of assembling the block during its manufacture.

A cooling tower fill block is known, containing vertical cylindrical corrugated pipes made of thermoplastic material, and sleeves made of the same material are placed in the channels between the pipes flush with their ends (see author's certificate SU 1359634, class F28F 25/08, 15.12.1987).

The disadvantages of such a sprinkler are the low reliability of the connection of sleeves and pipes, insufficient structural rigidity, relatively high aerodynamic resistance and low efficiency of heat and mass transfer.

The closest in technical essence and the achieved result is a cooling tower sprinkler block containing pipes and sleeves made of polymeric material, located parallel to each other and fastened together, while the sleeves are placed one at each of the end sections of the pipes and fastened to them by fusion of the ends sleeves and pipes flush (see utility model patent RU No. 28766, class F28F 25/08, 10.04.2003).

The implementation of the cooling tower sprinkler block described above made it possible to increase the structural rigidity and simplify the assembly of the sprinkler block. However, the heat exchange efficiency is not high enough, which is due to the low turbulence of the cooling air flow.

The objective of the utility model is to create a new device - a cooling tower sprinkler with the achievement of the following technical result: an increase in the intensity of heat and mass transfer.

This result is achieved by the fact that the cooling tower fill is made in the form of a module of layers of polymer mesh shells, made cylindrical, placed in all layers parallel to each other and welded at the ends of the module to each other at the points of contact, while the rows of mesh shells are installed at an angle (80- 85)° to the horizon, are located alternately with perforated corrugated sheets and are interconnected using horizontally placed polymer rods.

The figure shows a general view of the cooling tower fill unit.

The cooling tower fill is made in the form of a module of layers of polymer mesh shells 1, made cylindrical, placed in all layers parallel to each other and welded at the ends of the module to each other at the points of contact, while the rows of mesh shells are installed at an angle of (80-85) ° to the horizon , are located alternately with perforated corrugated sheets 2 and are interconnected using horizontally placed polymer rods 3.

Installation of mesh shells at an angle of (80-85)° to the horizon eliminates the possibility of free slip of water drops without contact with the surface of the sprinkler, increasing the efficiency of heat and mass transfer.

The design works as follows.

Recycled water is supplied to the cooling tower fill and passes through it under the action of mass forces, flowing down in a thin stream over polymer mesh shells 1 and perforated corrugated sheets 2. the process of heat and mass transfer, which contributes to an increase in the time of contact of water droplets with the air flow.

The main advantages of the proposed design of the cooling tower fill include the following:

design efficiency due to the exclusion of the possibility of free slip of the drip flow in the pipe space without contact with the surface of the sprinkler;

structural strength due to the high damping capacity of the mesh shells.

This utility model allows solving the problem of creating a cooling tower sprinkler block that is convenient for installation and transportation, while simplifying and reducing the cost of installation and repair work in cooling towers and can be used in devices for cooling water in the water circulation systems of industrial enterprises with direct contact of the cooled water and its cooling air.
