Energy-saving and environment-friendly water cooling method for cooling tower

Abstract

The invention discloses an energy-saving and environment-friendly water cooling method for a cooling tower. The energy-saving and environment-friendly water cooling method comprises the following steps: firstly, a water film is formed; secondly, heat exchange and evaporation are performed: high-temperature and high-pressure gas or liquid and other media requiring water cooling enter from an upper header of a coil part and are distributed to all cooling tubes, heat in the cooling tubes is transferred to the water film on the tube outer surfaces through the tube walls to enable the water film to evaporate, and heat exchange is finished; and thirdly, the water film is recovered. According to the energy-saving and environment-friendly water cooling method for the cooling tower, water and air are out of the tubes, and the temperature of running water is low, so that scaling is avoided; the energy-saving and environment-friendly water cooling method is suitable for regions in drought and water shortage, and economical and social benefits are more obvious; and in the North, circulation of cooling water can be avoided in winter, water stop for dry running can be realized, and the number of running axial flow fans can be reduced in spring and autumn.

Description

technical field [0001] The invention relates to a continuous washing method, in particular to an energy-saving and environment-friendly cooling tower water cooling method, which belongs to the technical field of washing. Background technique [0002] Thermal pollution is currently a serious concern. It is not acceptable to use water to cool chemical equipment, power generation turbines or refrigeration and air conditioning equipment, and then discharge the hot water directly. Hot process water should be cooled and discharged, or cooled and recycled ;Cooling water accounts for more than 70% of industrial water. Direct discharge of cooling water not only causes thermal pollution, but also causes a large waste of economy and resources. It is necessary to recycle and reuse these cooling water to alleviate the current shortage of water resources; In addition, In the process of industrial production, the phenomenon of energy consumption is very serious, so it is necessary to devel...
