The technical characterstic and operation principle of each part of the present invention are now introduced respectively：
1st, electromagnetic processor：There are two effects the part, when the high concentration concentrate given into heating rapidly and efficiently, second,
Electromagnetic Treatment is carried out to high concentration concentrate.
Electromagnetic processor uses the pipeline of titanium alloy material, and high-frequency electromagnetic coil, high concentration are wound outside the pipeline
Concentrate the inside of pipeline by, because the saliferous of the high concentration concentrate in pipeline is very high, i.e. charged particle and ion
It is very more, being mutually shifted for charged particle and ion and magnetic, produce induced-current and be changed into heat, described highly concentrated of rapid heating
Concentrate is spent, while described high concentration concentrate is in the presence of Lorentz force, the hydrone of low pole and other impurities
Charged ion does counter motion.During being somebody's turn to do, negative ions and particle mutually collide to form a number of " ion association body ",
This association body has enough stability, and substantial amounts of crystallization nuclei is formd in water, is carried out for follow-up evaporative crystallization
Prepare.
In addition, in the presence of high frequency electromagnetic energy, the hydrone in the high concentration concentrate is as coupling extremely son hair
Raw dipole polarization effect, is constantly polarized and produces distortion, deformation, reversion, vibration repeatedly, causes the bending of hydrogen bond and part disconnected
Split, and strengthen its molecular motion with additional electromagnetic field resonance, weaken the bound state between hydrone or association hydrone,
So that the various comprehensive chains of original association formation, bulk macromolecular（H2O）N is dissociated into single hydrone, eventually forms ratio
Relatively stable double moisture（H2O）2, make the increasing number of single hydrone, reduce the surface tension of water, make the overall performance of water
Change, add the activity of water, change the bonding state of hydrone and other ions, overflow and steam for follow-up vapor
Hair is got ready.
The electrical power size of electromagnetic processor handles the amount of concentrate, and the moisture content of last solid residue according to plan
To determine.
2nd, ultrasonic processor：The part is that electromagnetic processor is only supplemented one of charged particle and ion useful effect,
They use same titanium alloy pipeline, and a ultrasonic transducer is provided with beside the magnet coil of pipeline, composition
One focusing ultrasound reactor of pipeline, ultrasound make concentrate produce ultrasonic cavitation, and this had both caused non-between liquid internal
Often violent turbulence, the surface tension of concentrate being reduced again, promoting its internal energy to exchange, whether charged particle or ion be also
That uncharged organic matter has a good effect, ultrasound cavitation effect break concentrate it is originally thick while, ultrasound
The reunion that polymerization is advantageous to concentrate nucleus again is grown up, and is advantageous to follow-up evaporative crystallization.Ultrasonic processor also has an effect
The titanium alloy pipeline never fouling of circulation high concentration concentrate is to ensure that, and remains unimpeded, avoids general pipe
Road circulate concentrate when fouling and clogging quickly situation.
