The invention relates to the field of industrial circulating water descaling and scale inhibition, and provides a low-energy-consumption double-electrode induction diaphragm electrolysis circulating water descaling and scale inhibition device. The device comprises an electrochemical electrolysis device and a sand filtration separation device. In the device, a feed liquid pool is sequentially connected with a first pump body, a first valve, a first flow meter and an electrode cathode chamber through guide pipes; the electrode cathode chamber is sequentially connected with a third pump body, a third valve, a third flow meter, an induction cathode chamber, a sand filtering unit and a mixing unit through the guide pipes; a fourth pump body is sequentially connected with a fourth flow meter, an electrode anode chamber, a second pump body and a second valve through the guide pipes; and the second valve is sequentially connected with the second flowmeter, the induction anode chamber and the mixing unit through the guide pipes. According to the technical scheme, the electrochemical descaling and scale inhibiting device realizes descaling of circulating water with low energy consumption, can also reduce the pH value of a water body to realize a scale inhibition function, and has relatively high social and economic benefits.

Description

technical field [0001] The invention relates to the field of industrial circulating water treatment, in particular to a low-energy-consumption dual-electrode induction diaphragm electrolysis circulating water scale removal and scale inhibition device. Background technique [0002] With the development of my country's industry, the demand for fresh water has increased rapidly, and many cities have serious water shortage problems. Circulating cooling water is called the blood of industrial production systems. At present, the average domestic industrial water reuse rate is less than 53%, while industrial cooling water consumption accounts for about 70% to 80% of the entire industrial water consumption. Therefore, it is an effective way to save industrial water by innovating production technology, developing new water-saving technologies, transforming traditional industries, increasing the cycle concentration ratio of industrial cooling water, and maximizing the utilization of s...

[0017]In 2010, David Hasson[58] et al. developed a kind of Novel Seed System

[0022]The descaling rate of electrochemical descaling technology is low, the electrode area requirement is high, and the energy consumption is high; although ion exchange membrane and bipolar membrane can effectively realize acid-base Separation, improve removal efficiency In actual industrial use of peony stone, hydrophobic pollutants such as colloid, protein or oil remaining on the surface will greatly reduce the flux of the membrane and reduce production efficiency; the ion exchange membrane has poor mechanical properties and low separation efficiency. low and the outer membrane is easily polluted; when the concentration is too high, the selectivity of the bipolar membrane becomes poor and the purity of the product decreases
