Temperature regulation method for cooling tower

Abstract

The invention discloses a temperature regulation method for a cooling tower. The method is as follows: an inner side and an outer side of an air inlet of the cooling tower are respectively provided with a circle of water pipeline, nozzles are installed on the water pipelines, and in a summer, an air cooling area is formed by inner space and outer space around the air inlet through low temperature spray, thereby enabling high air wet bulb temperature to decrease after wet bulb passes through the cooling area; condensed water sprayed by the nozzles is obtained by supplying a water source by using the cooling tower, carrying out secondary condensation on the water source by using a refrigeration means, supplying obtained condensed water to the circles of water pipeline by using a water pump and then distributing the condensed water to each branch pipeline, and the condensed water is sprayed out by using the nozzles, a row of metal wires are vertically hung from top to bottom in the inner side of the air inlet of the cooling tower and hung above a water surface of a water storage tank, the metal wires are parallelly arranged so as to enclose the air inlet of the cooling tower, the bottoms of the metal wires are integrated into one by using a steel pipe, and a deicer is arranged on the steel pipe. According to the invention, the advantages of a simple structure, capacity of maintaining a temperature and cooling, safety, high efficiency, agility, utility and integration with nature are obtained; the cooling tower can automatically adjust air intake amount of the air inlet, and the temperature of cooling water is controlled to be in an optimal range.

Description

1. Technical Field [0001] The invention relates to a cooling tower of a power plant, in particular to a series of methods for cooling towers with natural ventilation in summer, eliminating freezing damage and reducing emissions in winter. 2. Background technology [0002] Cooling tower is an important heat and mass transfer device in the process of power generation and production of power plants. Its function is to dissipate the heat of high-temperature cooling water into the atmosphere through heat and mass exchange, and reduce the temperature of circulating cooling water. The cooling water function mainly relies on the mixing and contact of two hot and cold fluids in the tower. With the help of the partial pressure difference of water vapor between the two fluids, the hot fluid is partially evaporated and cooled by itself. [0003] The composition of the hyperbolic natural draft cooling tower can be divided into two parts: the tower structure and the water spray device. Tower st...

AI Technical Summary

Problems solved by technology

The cooling tower of the conventional wet cooling system commonly used at present discharges a large amount of waste heat to the environment through evaporation while cooling the circulating water. This heat exchange method leads to a large amount of evaporation water loss.
