Abstract
Изобретение относитс к теплоэнергетике, в частности к способам охлаждени воды в градирне системы оборотного водоснабжени , и может быть использовано на тепловых и атомных электростанци х. Цель изобретени - повышение интенсификации тепломассообмена. Сущность: способ осуществл етс путем смешени охлаждаемой воды с потоками окружающего и сжатого воздуха, охлаждаемую воду смешивают с потоком сжатого воздуха перед подачей на охлаждение, при этом сжатый воздух подают в количестве 5 - 15% от расхода охлаждаемой воды.The invention relates to a power system, in particular to methods for cooling water in a cooling tower of a circulating water supply system, and can be used in thermal and nuclear power plants. The purpose of the invention is to increase the intensification of heat and mass transfer. Substance: the method is carried out by mixing the cooled water with ambient and compressed air flows, the cooled water is mixed with the compressed air flow before being fed to the cooling, while the compressed air is supplied in an amount of 5-15% of the flow rate of the cooled water.

На чертеже изображена градирн , реализующа предлагаемый способ охлаждени .The drawing shows a cooling tower implementing the proposed cooling method.
Градирн содержит корпус 1 с окнами 2 дл подвода охлаждающего воздуха , трубопровод 3 подачи охлаждаемой воды с вертикальным сто ком 4 подачи охлаждаемой воды, сообщенным в нижней части с трубопроводом 5 подвода сжатого воздухаThe cooling tower comprises a housing 1 with windows 2 for supplying cooling air, a pipeline 3 for supplying cooled water with a vertical stand 4 of cooling water supply, communicated in the lower part with a pipeline 5 for supplying compressed air
Охлаждение воды в градирне согласно предлагаемому способу осуществл - етс следующим образом„Cooling of water in the cooling tower according to the proposed method is carried out as follows.
Нагретую воду из теплообменника (не показан) подают по трубопроводу 3 в вертикальный сто к 40 В нижнюю часть сто ка 4 по трубопроводу 5 подают сжатый воздух в количестве 5 - 15% от расхода охлаждаемой воды. Подача воздуха в таком количестве создает подъемную силу дл потока охлаждаемой воды за счет присутствующих в нем пузырьков воздуха, что позвол ет снизить гидравлическое сопротивление и, следовательно, увеличить скорость получаемой водовоздупгной смеси на выходе из сто ка 4, в результате чего при разбрызгивании охлаждаемой воды происходит ее дробление с более мелкой дисперсностью и увеличенной плотностью орошени .The heated water from the heat exchanger (not shown) is supplied via pipeline 3 to the vertical one to 40. To the lower part of the stand 4, pipeline 5 is supplied with compressed air in an amount of 5-15% of the flow of cooled water. Air supply in such an amount creates a lifting force for the flow of cooled water due to the air bubbles present in it, which reduces the hydraulic resistance and, consequently, increases the speed of the resulting water-air mixture at the outlet of stand 4, resulting in splashing of the cooled water crushing it with finer dispersion and increased irrigation density.
