Embodiment 1

[0055] Adopt the present invention to be applied to the pipeline circulating cooling water of a thermal power plant:

[0056] The circulating cooling water pipeline of a certain factory can clean out 28kg of scale inhibitors in one month. Let the factory install the corrosion and scale inhibition device according to the instructions of this application, and add 11kg of the corrosion and scale inhibition material prepared by this application to the circulating cooling water of the pipeline. Connect the device to the power supply and turn on the device, the nano-soft ferrite in the nano-corrosion and scale-inhibiting material performs a helical movement in the helical forward magnetic field generated by the device, and follows the water flow through the entire pipeline. The PESA and special CQDs in the corrosion and scale inhibition materials soften the scale inhibition texture, which is destroyed by the moving nano soft magnetic ferrite. After the installation of the device of...

Abstract

The invention provides a novel pipeline corrosion and scale inhibition method and device, and relates to the technical field of circulating water treatment.The novel pipeline corrosion and scale inhibition method comprises the following operation steps of S1, preparing nanometer soft magnetic ferrite of a branch net structure, S2, magnetically driving a material, and S3, recycling and regenerating the material. The corrosion and scale inhibitor can effectively destroy formation of scale inhibition, can attach a layer of protective film on the inner wall of a pipeline to prevent corrosion of the pipeline, can inhibit excessive reproduction of microorganisms in the pipeline, has good corrosion and scale inhibition performance, and meanwhile, the used materials can be recycled, so that the corrosion and scale inhibitor is economical, green and pollution-free to the environment, and is suitable for industrial production. The treated circulating cooling water can reach the national emission standard, and the electromagnetic coils are arranged in the multiple cable limiting frames in a limiting mode, so that the electromagnetic coils are more stable in the using process.

Description

technical field [0001] The invention relates to the technical field of circulating water treatment, in particular to a novel pipeline corrosion and scale inhibition method and device. Background technique [0002] In my country, industrial circulating cooling water accounts for more than 70% of industrial water. However, due to the continuous evaporation of circulating water in the process of circulating cooling, the concentration of salt in the water continues to rise, exceeding the solubility of certain salts and causing precipitation. Common salt deposits include calcium carbonate, calcium phosphate, magnesium silicate and other scales. The scale produced by salt precipitation is relatively dense in texture, which can effectively reduce the heat transfer efficiency. A scale thickness of 0.6mm can reduce the heat transfer coefficient by 20%. At the same time, the organic matter in the water, microbial colonies and secretions, sediment, dust, etc. constitute the scale, wh...
