Energy Saving And Emission Reduction In Circulating Water System

In recent years,with the development of economy,industrial water consumption is increasing,while cooling water accounts for about 70 % of total industrial water consumption.Therefore,the design of circulating cooling water in enterprises is particularly important.China is a water shortage country,in response to the call of national water saving and emission reduction,how to save water,use the existing water resources,and put forward new requirements for the design concept of the circulating water system.In this paper,the important three cooling towers,circulating water pumps and users in the circulating water system,describes the history of each of these three,and what are the emerging technologies,and the problem of old system solutions.For example,the cooling tower in the current circulating water system is the traditional jili cooling tower,and the water fan cooling tower mentioned in this paper uses the turbine drive fan rotation to replace the motor drive,the drive mainly depends on the overbottom pressure of circulating water backwater.The water saving fog-reducing cooling tower is mainly from the elimination of the traditional jili cooling tower water quantity to consider,not only the amount of water,achieved the effect of energy saving,and eliminate the fog caused by the evaporation of water vapor around the surrounding atmosphere,reduce the impact on the surrounding environment.At present,the traditional circulating water pump efficiency is about 60 % ~ 70 %,and the emerging efficient energy-saving pump efficiency can reach 85 % ~ 90 %,and the efficiency is improved about 15 %?The new technology of water fan cooling tower,water-saving cooling tower and high efficiency energy-saving water pump have great effect on the energy saving design of the circulating water system.the cooling effect of the device served by the circulating water system directly affect the energy consumption of the whole water system..
