The cooling system comprises a cooling tower, a heat exchanger, a circulating water pipeline and a cooling tower water pump, wherein a water kinetic energy wheel fan is arranged in an air tube; a circulating water input port is dead against the water kinetic energy wheel fan, and the kinetic energy of circulating water directly drives the water kinetic energy wheel fan to rotate; and an ultrasonic scale preventing and removing device is arranged in a second water feeding pipe behind the heat exchanger. The circulating water cooling system for cooling towers, disclosed by the invention, adopts a closed-loop intelligent control mode; and the flow and pressure of cooling water in the cooling tower circulating pipeline are main physical parameters of heat exchange efficiency, and the rotating speed of a water turbine blade, the frequency control of the water pump and the starting of the ultrasonic scale preventing and removing device are controlled through sampling the change values of the flow and pressure, thereby achieving an effect of improving the heat exchange efficiency according to the heat exchange requirements.

Description

technical field [0001] The invention relates to a circulating water cooling system, in particular to a cooling tower circulating water cooling system which comprehensively uses cooling towers, heat exchangers, circulating water pipelines and cooling tower water pumps for intelligent energy saving. Background technique [0002] Cooling tower closed-loop circulation cooling system plays a very important role in industrial production and daily life. But we should also clearly see the problems in the operation of the circulating cooling system: [0003] (1) The circulating cooling system of the cooling tower adopts the fan for heat exchange, adopts the electric drive method and does not use the potential kinetic energy and potential energy of the circulating water, and consumes a large amount of energy; [0004] (2) The cooling tower water pump that has not undergone energy-saving transformation, regardless of whether the temperature and heat dissipation requirements change, al...

AI Technical Summary

Problems solved by technology

[0003] (1) The circulating cooling system of the cooling tower uses fans for heat exchange, and adopts electric energy drive mode without utilizing the potential kinetic energy and potential energy of circulating water, which consumes a lot of energy;

[0004] (2) The cooling tower water pump that has not undergone energy-saving transformation, regardless of whether the air temperature and heat dissipation requirements change, always operates under the power frequency condition, resulting in unnecessary waste of electric energy;

[0005] (3) The long-distance circulation pipeline of the circulating cooling system is seriously fouled and the pipeline is blocked, resulting in a decrease in heat exchange efficiency and an increase in the temperature drop requirements of the cooling tower

[0006] These problems have had a serious impact on industrial production and daily life, resulting in a decline in production efficiency, a large loss of electric energy and water, and a serious waste of energy. Far

Relatively speaking, a large number of industrial and mining enterprises did not pay much attention to the problem of circulating cooling system, but turned a blind eye to it and neglected to manage it, which has become a big blind spot in factory energy management

Moreover, the managers of most factories have obvious misunderstandings, thinking that this part of energy consumption seems to have no room for saving
