Description
Technical field
The present invention relates to power generation, petroleum and other use heat exchange equipment industrial circle, more particularly to one kind based on string
Join the alternating electromagnetic field generating device of resonance principle.
Background technique
In fields such as power generation, chemical industry and petroleum, scale formation of the circulating cooling medium on heat exchange tube wall, to industrial production
In heat exchange equipment it is very harmful, after use all the year round, a large amount of dirt can be generated in heat exchanger tube, heat exchange efficiency is caused to decline,
Energy waste or even equipment damage are caused, a series of economic and technical problem is brought.To solve scale problems, traditional is removed
Dirty method is mainly chemical cleaning method, and such method effect is preferable, but the disadvantage is that use cost is high, needs a large amount of chemical drugs
Agent, and to be equipped with a large amount of professional and operate, serious pollution can be also caused to environment；Electromagnetism descaling method operation at
This is low, pollution-free, quick using simple.
In terms of the effect major embodiment following two of electromagnetic field scale suppression:
1, under the processing of electromagnetic field, cation and anion in medium all can be by the effects of Lorentz force, still
The direction of the Lorentz force of two kinds of ions be it is opposite, positive and negative ion is done under the action of Lorentz force along opposite direction
Circular motion, this just considerably increases the probability of ion collision, precipitating particle is combined into after ion collision.This process can make to be situated between
A large amount of small particles are generated in matter, such little particle is easy to wash away with water flow, is not easy to be adhered on heat-transfer surface, causes dirt
The accumulation of dirt.On the contrary, ion is easy to be adsorbed to plane of crystal and heat exchanger just face, crystal meeting if the not effect in magnetic field
It becomes larger to form big dirt particles, and is firmly adhered on heat-transfer surface, heat exchange efficiency is caused to decline；
2, with most commonly used medium water and CaCO3For dirt, the cluster of hydrone can become under the influence of a magnetic field
Change.Under general conditions：Hydrone be in the form of cluster existing for, exactly multiple hydrones connect under the action of hydrogen bond
Together, molecular cluster is formed, since water is polar molecule, when handling by electromagnetic field, water generates the effect of power, so that molecule
It respectively scatters, cluster becomes smaller or disappears, and water molecule cluster, which becomes smaller, can promote the solvability of water, increases to CaCO3Particle it is molten
Xie Liang, if the hardness of water is smaller, the water after magnetic treatment can also dissolve a part of already existing scale, to embody
The effect of scale suppression out.
According to the law of electromagnetic induction it is found that under the conditions of permanent magnetism, the induction force that ion is subject to is from water flow along perpendicular to magnetic
What field direction was flowed and was generated, and the advantage of electromagnetic field is to generate high-frequency alternating magnetic field.It is with the electromagnetic field of 1KHz
Example, magnetic direction can change 1000 times in 1 second, then variation of the induction force from magnetic direction that ion is subject to, this
The intensity of induction force is thousands of or even tens of thousands of times bigger than under the conditions of permanent magnetism, and a large amount of experimental study has also confirmed this conclusion.Such as
Fruit can realized high-frequency while realize high magnetic field intensity, then the induction force that ion is subject to can further increase, so
The advantage of electromagnetism field processor is that magnetic treatment is high-efficient.
At present, it is common to use alternating magnetic field generating device principle as shown in Figure 1, inverter generate the adjustable friendship of frequency
Galvanic electricity pressure, coil be with copper wire winding at single-layer solenoid, inverter is directly connected on solenoid, with alternating current straightening
Driving coil is connect, the alternating electromagnetic field of certain frequency is generated inside solenoid, although this device can also generate alternating electromagnetism
, but magnetic field strength is very weak, only up to reach 30GS.
There are two the weak reason in magnetic field is main：
1. single layer coil causes magnetic field strength weak；
2. there are induction reactance when being worked in current circuit due to coil, induction reactance can hinder electric current to flow through coil, make in coil
Current limit a very little value, magnetic field strength and electric current be it is directly proportional, electric current is small so magnetic field is weak.
Basic reason still due to induction reactance the problem of, the induction reactance of alternating current circuit coil calculates as shown in formula 1, wherein ω
The angular frequency for the alternating voltage that inverter generates, L is the inductance value of coil, the inductance value of the number of plies of coil more multi-coil more
Greatly, it will lead to induction reactance increase, eventually lead to that the electric current flowed through in coil is smaller, and magnetic field strength is weaker.
Summary of the invention
The present invention is directed to the existing issue and Improvement requirement of alternating electromagnetic field generating device, creative introducing series resonance
Principle devises a kind of alternating electromagnetic field generating device based on series resonance principal, mutual by the capacitive reactance and induction reactance of capacitor
It offsets, solves the problems, such as induction reactance, induction reactance is made to disappear, to break limitation of the inductance to electric current in coil, increase substantially magnetic field
Intensity, electromagnetic field intensity highest can achieve 2000GS at present, if coil selects the lower conductor of impedance, magnetic field strength can be with
Reach higher level, and there is no the upper limit, this is also the advantage place of the device.
