Background

The water consumption of industrial enterprises is large, and the influence of discharged waste water on the environment is also large. At present, in order to save energy and protect environment, circulating water is generally used in industrial production, the circulating water is generally obtained by simply treating raw water, and when the circulating water circularly flows in a boiler and a heat exchanger of an air conditioning system, due to the temperature rise of the circulating water and the concentration of a water body, impurities such as suspended matters, metal ions, water-soluble colloids and the like in the circulating water can generate scaling on a heating surface.

The thickness of the scale has direct and close relation with energy consumption, and the thicker the scale is, the larger the energy waste is. The heat conduction performance of the heating surface of the boiler is deteriorated due to the scaling, the heating surface can be overheated or over-burnt, and even the explosion of the boiler can be caused when the scaling is serious. Meanwhile, scale formation also increases under-scale corrosion to the heating surface and shortens the service life of the boiler. Furthermore, metal ions in the circulating water can corrode and pollute a circulating water pipeline and water system equipment, and the circulating water is deteriorated to generate red rust water after being used for a long time, so that the water quality cannot meet the requirement, and the equipment is corroded.

At present, the commonly used methods for descaling and scale inhibition mainly include chemical methods and electromagnetic treatment methods. The chemical method is mainly to add chemical additives into the circulating water periodically or to adopt an ion exchange method to soften the circulating water to prevent scale formation, and the formed scale is usually removed by adopting an acid washing mode, but the chemical method can cause secondary pollution to the environment. The existing electromagnetic treatment method has an unsatisfactory descaling effect on circulating water, and can generate a large amount of sewage rich in impurities such as suspended matters, metal ions, water-soluble colloids and the like, so that the production cost of enterprises is increased.
