Description

one

The invention relates to the field of heat and power engineering and relates to the cooling of recirculated water from power plants and industrial enterprises in bryagal cross-counter cooling towers.

A method of cooling water in a cooling tower is known, in which water is successively fed from top to bottom in irrigation elements located along the fl fl.

However, a large cooling surface, especially in the second floor, is required for efficient water cooling, which requires considerable capital expenditures. In addition, staged water distribution requires an increase in the power of the circulation pumps as compared to water distribution systems located at the same level.

The closest to the proposed technical essence is the method of cooling water in the cooling tower by feeding it into the cross-flow and counter-flow stages successively washed by the air flow, collecting water in the swimming pool and diverting it to the consumer 2.

In the cooling tower, but as the air moves, the temperature gradient between the cooled water and air is reduced, and as a result of it, part of the hot circulating water in the fine-grained stage is not efficient enough. This leads to undercooling of the entire flow, and therefore to reduce the efficiency of the method.

The purpose of the invention is to increase the efficiency of the method.

For this, according to the proposed method, water from the basin in the amount of 0.2-i is sent to the cross-flow stage of the cooling tower.}, 5 the total flow rate of the cooled water and after cooling is returned to the pool.

This brings the process of cooling water closer to a more efficient counter-flow pattern, when the air, passing through the cooling tower, encounters more and more hot water on its way.

In the drawing, a cooling tower is schematically depicted to implement the proposed cnt soba.

In the exhaust tower 1 of the cooling tower, there is a countercurrent stage 2 of the water distribution unit, and in the ring vestibule 3 - the transverse stage 4. Pipeline 5 is designed to supply hot water to general heating apparatuses. A catchment basin 6 is placed under the water distribution pipes. The pipeline 7 and the pump 8 are intended for supplying water from the basin 6 to the cross-section of the Aren 4 water distribution area.

Hot water is supplied through conduit 5 to the progivolt stage 2 of the water distribution gel, where it is dispersed and the cooling air moving upwards moves to meet on its way. Partially cooled water is collected in pool 6, then water in an amount of 0,, 5 og of water collected in the pool is supplied by pump pump 8 through pipe 7 to crossflow point 4 of the water distributor, from where it is drained, cooled by transversely moving air flow, and mixed in the pool 6 with water cooled in the pill box 2, the cooled water through the pipeline 9 is returned to the consumer, i.e. to heatmixers.

Pa all the way the air moves in the area irrigated with water provides

B1 is the enhancement of the temperature gradient between air and water. Re-supplying chilled water to the stage 4 of the water distributor increases the depth of its cooling, which gives a significant economic effect.
