The present invention relates to a device for treating a fluid by using a magnetic field and vibration generated by the ultrasonic wave at the same time. More specifically, to induce ionization polarity of diamagnetic molecules in a liquid while converting ultrasonic energy into vibration energy, the phenomenon of fluid cavitation It is a device to treat the fluid with strong energy by adding energy to the fluid due to over oxidation.

In general, the fluid treatment method has been developed and spread in the physical and chemical methods such as the electromagnetic hydrodynamic method (magneto hydrodynamic) using the magnetic field and the method of adding acidic chemicals to the chemical method. The method using only the magnetic force line, the former method, permanently magnets and electromagnets to charge the particles contained in the fluid by the magnetic force lines and to cause structural changes to prevent the formation of scale.

The theoretical background of the fluid treatment by magnetic field is that if a strong magnetic body is flowed perpendicularly to the velocity direction of the fluid to induce ionization properties in the diamagnetic body molecules in the fluid, qV × B (q: charge amount, V: velocity, B: magnetic field) direction The force acts to exert the induced polarity. In this case, to obtain ionization phenomenon in the fluid, a strong magnetic force line from the outside is required or the speed of the fluid must be increased. However, there is a drawback of cost and volume increase to have a magnetic body with a strong magnetic force line, and there is a limit to increase the velocity of the fluid, and also has a defect that the stability of the fluid type and flow rate cannot be proved. . In addition, the ultrasonic wave is a sound wave in the frequency range which is inaudible to human beings and has a high frequency of more than 20000 Hz. An example of a fluid treatment apparatus by the generation of such ultrasonic waves is Korean Patent Publication No. 89-1302 (88. 4. 29 publication).

The patent consists of an ultrasonic generator and a receiver adapted to homogeneously treat the fluid flowing in the water pipe. Although it has been thought to be effective to directly project the ultrasonic wave to the fluid as described above, there is a problem that it is practically impossible to apply the ultrasonic wave to the entire fluid to homogeneously treat the fluid.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to change the ultrasonic wave into a pressure wave caused by vibration so as to effectively act on a fluid to prevent generation of scale.

Still another object of the present invention is to provide an apparatus that maximizes the treatment effect by treating a fluid using ultrasonic pressure waves and magnetic fields at the same time.

To this end, the present invention, when the diaphragm vibrates by arranging a plurality of permanent magnets on one side of the conduit for passing the fluid to be treated to face the same poles and installing a diaphragm vibrating by a plurality of ultrasonic vibrators on the other side thereof. The liquid is compressed and expanded repeatedly, and the aeration of bubbles generated at this time promotes ionization and prevents scale formation of metal complexes.

DETAILED DESCRIPTION Hereinafter, embodiments of the present invention will be described in detail with the accompanying drawings.

Reference numeral 1 denotes a conduit through which the fluid to be treated passes, and a plurality of permanent magnets 2 are arranged inside or outside the conduit 1 such that the same poles face each other. On the other side of which the permanent magnet 2 is disposed, a plurality of ultrasonic vibrators 3, in the embodiment of the present invention, two are spaced apart at regular intervals and wide at the tip of the vibrating shaft 4 protruding into the conduit 1. The plate-shaped diaphragm 5 is fixedly installed.

Symbol (6) is a control device for adjusting the intensity and amplitude of the ultrasonic wave in consideration of temperature, flow rate and acidity of the ionized water, for this purpose, the conduit (the thermometer 7 for detecting the temperature and acidity inside the 10 and An acidity detector 8 is provided, and although not shown, a flow rate meter or the like is installed.

In the present invention, the fluid is treated according to the following principle.

When the magnetic field is applied to the fluid by the permanent magnet (2), the force of Fleming's left hand law acts on the fluid surface. When the magnetic field acts on the fluid, it breaks down to a steady state with the water molecules that are responsible for scale formation. In addition, when the ultrasonic vibrator 3 operates, the diaphragm 5 fixed to its tip vibrates by the frequency.

Here, the vibration wave caused by the vibration is transmitted to the fluid as ultrasonic waves itself, and the pressure applied to the fluid is periodically changed by the vibration of the diaphragm, and the liquid is repeatedly compressed and expanded.

If the oscillation shaft 4 moves forward while the diaphragm 5 vibrates one cycle, the fluid will be compressed and expand back. When the fluid expands rapidly, a negative pressure is generated and a vacuum part of the fluid, that is, a cavity, is formed.

At this time, gas such as air dissolved in the surrounding liquid expands and gathers in the cavity. The next time the negative pressure is positive, the liquid is compressed and a high pressure is applied to the cavity, and the cavity is crushed, or when small bubbles gather around and become large bubbles, aeration creates large pressure and high temperature. Ionization occurs by the discharge of bubbles in the liquid, and it is possible to eliminate and prevent scale formation of the metal complex. Activated oxygen in bubbles during cavitation is due to ionization, which shows weak oxidation, and can be used in water purification plants, swimming pools, and wastewater treatment plants because it can kill bacteria and algae. In addition, the properties of the ultrasonic wave have the effect of promoting the direct chemical reaction of the fracture-dispersing particles, so that the fluid can be treated by the cavitation caused by the vibration change of the ultrasonic wave.

Accordingly, the present invention is to adjust the degree of vibration and sound pressure and positive pressure generated by the ultrasonic wave according to the viscosity and flow rate of the fluid and to improve the stability and reliability by the overlapping action of the magnetic lines.

Here, the driving force of the ultrasonic wave is determined by multiplying the effective area of the vibration wave by the sound pressure when the sound pressure is applied uniformly to the vibration wave. Therefore, it is preferable to form a wide area of the vibration wave. It is installed in the longitudinal direction to uniformly transmit the shock wave by vibration to the fluid. Especially, if the vibration wave is concentrated on the connection of N pole with high density of magnetic line and N pole, S pole and S pole, Synergism makes it more effective in preventing scale formation.
