Description

technical field [0001] The invention relates to a signal generator for physical descaling, in particular to a signal generating device for inhibiting corrosion or scaling of metal pipelines. Background technique [0002] Cooling water accounts for 67-80% of all water consumption in modern factories. With the development of industry, enterprises have generally used circulating water systems and increased the concentration of circulating cooling water. However, after increasing the concentration ratio, corrosion and scale inhibition treatment must be carried out; because with the increase in the concentration ratio of circulating water, the scale-forming salts and corrosive ions in the water will also increase exponentially, which will also cause more serious problems. Scaling and corrosion problems.

For example: the electrode method is to directly contact the electrode with the solution, which is easy to oxidize and corrode the electrode, and it is not convenient for online construction when there are pipelines arranged; another example is to use a coil structure for energy transfer, and its coupling efficiency is extremely low. The frequency range is also very narrow; while using other magnetic strip structures for energy transfer also has the defects of large magnetic flux leakage and low coupling efficiency
