Low-cost maintenance-free electrochemical treatment technology device system for circulating water scale

Abstract

The invention discloses a low-cost maintenance-free electrochemical treatment technology device system for circulating water scale. The system comprises a circulating water tank; and the interior of the circulating water tank is provided with scale absorbing electrodes, a water level in the circulating water tank submerges the scale-absorbing electrodes, each scale-absorbing electrode is connectedwith one corresponding controller through one corresponding scale absorbing conductor, and the controllers are connected with an input power line. According to the system provided by the invention, an improved application method that the scale-absorbing electrodes are directly put into the water tank is adopted, so that the input costs are less, and full-automatic cleaning of the water scale adsorbed on the electrodes is fully realized, and maintenance-free operation in the operation process is realized; and workers do not need to extract the electrodes frequently, so that the electrodes canbe put in optimal treatment positions in the water tank, and better treatment effects can be realized.

Description

technical field [0001] The invention relates to a circulating water physical method treatment technology, in particular to a low-cost, maintenance-free circulating water electrochemical treatment technology device system. Background technique [0002] In industrial production, in order to avoid that the production process cannot be carried out smoothly due to the temperature rise of the equipment, cooling must be carried out. Water has good chemical stability, high boiling point, and large heat capacity. At the same time, water has a wide source, is easy to transport and distribute, and is cheap. For this reason, water is often used as a cooling medium in industrial production, called circulating water. According to statistics, industrial water accounts for about 80% of the total urban water consumption on average, and industrial cooling water accounts for the largest proportion. [0003] During the operation of circulating water, the main problems are scale, dirt, corrosio...

Problems solved by technology

[0005] Disadvantages of chemical dosing method: chemical agents are highly targeted, time-sensitive, easy to fail, and the effect is unstable

Its disadvantage is that it needs to be cleaned regularly after the electrode is scaled. Whether it is manually extracting the scale electrode or using a crane to extract the scale electrode, it is necessary to manually clean the scale adsorbed on the scale electrode.

It not only requires a lot of maintenance and wastes manpower and material resources, but also limits the location of the scale suction in the circulating pool. Because the scale suction electrodes need to be extracted continuously, the electrodes are generally placed on the edge of the circulating pool for the convenience of extraction.

[0009] The advantage of the bypass type is that it can automatically remove the scale of the scale suction electrode, but the equipment structure is complex, and its overall cost is 50% higher than that of the direct input type in terms of processing, production, packaging and transportation, on-site installation, and operating costs. above

In addition, after a long period of operation, the number of fault points will gradually increase, and the daily maintenance costs will increase, and special personnel are required for maintenance. In practice, this bypass type has been abandoned by users due to the large amount of maintenance.
