The invention relates to heat power engineering, in particular, to devices for cooling the zod, a cooling tower of the drip type, and can be used in the presence of petroleum products and similar contaminants in cooled water, excluding their possibility to use film coolers of type a. also in the biological treatment of wastewater, for example, biofilters.

The purpose of the invention is to increase the efficiency of heat exchange and the reduction of aerodynamic drag.

; Fig „1 depicts the element of the cooling tower nozzle (axonometric) 5 on Fig. 2; a variant of the layout of the elements nasad | Ki with countercurrent movement of air water; in fig, 3 - the same, with alternating movement of water and airflow. .

Element 1 of the cooling tower nozzle (Fig. 1) contains lattice disks 3 intersecting along a common axis with stiffener edge 4 circumferentially fastened in; and the brightness perpendicular to axis 2, ring 5, dividing the surface of element 1 by spherical triangles b.

The ribs 4 of the rigidity are circumferentially connected by bridges 7 forming on the spherical triangles 6 of the lattice 8 arranged in a checkerboard pattern

The 11 element 1 can be used as either an jjtH or water trap as “For this and the organization (2, 3) arrange two 1 supporting 9 and 10 gratings, from which tuileous irrigation can be found. from elements 1, and jja, the second drip drop layer 12 of the same elements, - The irrigation layer and the drip drop layer are arranged sequentially in the direction of the moving and cooling air,

Figures 2 and 3 show the water distribution system 13, the reservoir 14 and the fan 15,

The cooling tower with the proposed element of the nozzle works as follows:

The heated water is uniformly sprayed over the irrigation layer 11 using the water distribution system 13 (FIGS. 2, 3) ,, Leaking from top to bottom through the developed system of canals

This irrigation layer, formed by trellis discs 3 and spherical triangles 6 of the elements 1, repeatedly breaks up water into droplets, thus re-shedding it, which contributes to the intensification of heat exchange between water and air. The cooled water enters tank 14 ,.

B of the prototype cooling towers (FIG. 2) cooling air enters the irrigation section 11, and in the crossflow (FIG. 3) it is on the side of the irrigation layer 11. It passes through the channels of this layer in the first case vertically upwards towards water, and in the second - horizontally, approximately at a right angle to the direction of water flow. The air contacted in the branched channels of the elements 1 with heated water cools it, while it is humidified, heated, carries with it the smallest droplets of water and enters the drop-drop layer 12.

In this layer, the elements 1 form

(as in the irrigation layer 11) the times-i are branched with a network of optically dense (when viewed from above) channels. When the air flow passes through these channels, the water droplets come into contact with the lamellar surfaces of the spherical elements 1, on which they settle, and the air is ejected from the cooling tower to the outside. The droplets deposited on the lattice surfaces of the elements are enlarged and fall down in a stream. At the same time, in counterflow cooling towers (FIG. 2) they enter the irrigation layer 11, where they are mixed with the main flow of water, and in cross flow ones (FIG. 3) they flow into the reservoir 14,

The proposed design of the ball element allows the maximum use of the external surface of the element and its internal volume for the contact of media; to give the element optical density, i.e. when a beam passes through an element in any direction, it encounters an obstacle in the form of

g

jumpers; eliminate the possibility of the elements being inserted into each other when laying with a layer; apply the industrial method of making elements of thermoplastic material with the help of injection molds in one step.

Thus, the use of the described element in cooling towers increases the efficiency of heat exchange and reduces aerodynamic resistance to the movement of air.
