Abstract

Invention m. It is used to cool the circulating water of power plants and industrial enterprises and allows to increase the intensity of heat and mass transfer. Cooling water through radially located water supply ppmm pipelines (TP) enters the water distribution TP 4, placed between the water supply TP in several rows with abrasion in terms of such polygons. Through the openings 5 of TP 4, water is supplied to the over-disposed reflectors 6. Next, the water flows into the gap 10 between the grid 7 and the elastic element 9 placed on the reflector 6 and distributed over the grids 7 placed vertically on both sides of the TP 4. Air enters the vertical channels between the sprinkler-forming nets 7 within each TP 4. Air passes through the nets of the nets 7, breaks the film of flowing water. In this case air is bubbled through the water layer. With an increase in the water head, the gap 10 increases, thus preventing the tearing of a film of water flowing along the grids 7. The latter are made with different lengths, increasing in steps from the periphery of the tower to the center. From the ends of the grids 7, the water is discharged onto inclined plates located in the wedges between the grids 7 of the adjacent TPs. 1 hp ff, 5 ill. from the next

Description

one

The invention relates to heat masses for exchangeable apparatuses, namely tower cooling towers for cooling the circulating zod of power plants and industrial plants.

The purpose of the invention is to increase the intensity of heat and mass transfer

FIG. 1 shows the cooling tower j, a general view of FIG. 2 is a section A-A in FIG. 1; FIG. 3 is an in-line distribution pipe with reflectors; FIG. 4 shows a sector with water distribution pipes and a sprinkler; Fig. 5 shows an embodiment of the irrigation system.

 bodies with nets of various lengths.

The cooling tower contains a tower 1 with a central tower 2, radially placed water supply pipelines 3, water distribution pipelines 4, placed between water supply pipelines 3 in several rows with the formation of similar polygons in terms of water. holes 5. Reflectors 6 are installed over the water distribution pipes 4. The cooling tower sprinkler is made in the form of grids 7 placed vertically on both sides of the pipelines 4 and piping with pipes 4 and collections, performed in the form of inclined plates 8, located in the intervals between the grids 7 of the adjacent 35 limiting pipelines, open 30

repentant water, I will organize air bubbling through a layer of water. With an increase in water pressure, the elements 9 move away from the grids 7; the gap 10 increases in proportion to the flow rate of water, thus preventing the film of water flowing through the grids 7 from breaking off. Heat and mass transfer of air and water occurs under conditions of intense turbulence in the flow of water and air with a significant increase in the contact surface of these heat transfer media. The cooled water drains on the grids 7. inclined plates 8, from where the jets are poured into the pan 13,

The water to be cooled, the € T access to the tower 1 through one hundred to two, is distributed through the supply lines 3 and then enters the water distribution pipes 4. Through the openings 5 water is pumped to the reflectors 6, flows through it the walls in the gap 10 between the grid 7 and the elastic element 9 and further distributes with the grids 7,

The air injected by the fan 12 enters the vertical channels between the grids 7 within each pipeline 4, and then, passing through the grids of the grids 7, breaks the film
