Magnetic water treatment method based on combined magnetic field

Abstract

The invention relates to a magnetic water treatment method based on a combined magnetic field. The magnetic water treatment method is characterized by comprising the following steps: connecting a water pipe made of a segment of non-magnetic material into a heat exchanger inlet; establishing a magnetic water treatment pipeline with an alternating magnetic field and adjustable permanent magnetic field combined magnetic field on the water pipe made of the segment of non-magnetic material; setting the flow rate of a working medium, the frequency and power of an alternating magnetic field and the strength of the adjustable permanent magnetic field; delivering the working medium to the segment of the magnetic water treatment pipeline of the combined magnetic field to be subjected to magnetic water treatment, and meanwhile, monitoring a water quality parameter, dirtiness resistance and other parameters on line to determine the strength of the optimal permanent magnetic field of the treated working medium, the frequency and power of the alternating magnetic field and other parameters. When the magnetic water treatment method is used, an online monitoring system is started to acquire a water quality parameter signal, a temperature signal, a flow rate signal and other signals, all the signals are input to a computer and computed to obtain the dirtiness resistance of a heat exchanger, and the magnetic field parameter corresponding to the optimal magnetic treatment effect under the flow rate is obtained through comparative analysis.

Description

technical field [0001] The invention relates to a countermeasure against fouling of heat exchange equipment in high-energy-consuming industries, in particular to a magnetic water treatment method. It is a magnetic water treatment method based on a combined magnetic field. Background technique [0002] In various heat exchange processes in the prior art, more than 90% of the heat exchange equipment has fouling problems. Fouling of heat exchange equipment, on the one hand, will reduce the heat transfer rate and increase fuel consumption; on the other hand, it will often cause local overheating or overtemperature, resulting in a decline in the mechanical properties of the equipment, and in severe cases, production accidents. The scale problem of heat exchange equipment in power plants has always been concerned by the industry. The electromagnetic treatment method in the commonly used physical method of scale suppression is favored by the industry because of its advantages of c...

However, so far, there is no report to give the parameters such as magnetic field strength and frequency corresponding to the best electromagnetic water treatment effect.

In addition, the mechanism of action of electromagnetic field anti-scaling technology is not yet clear, and the effect of anti-scaling is still unstable. These factors have hindered the further development of electromagnetic anti-scaling technology.
