Abstract

The invention is a device for electromagnetic fluid treatment in which at least four parameters can be set directly or indirectly. These are largely independent signal components (e.g. upper, lower limit frequency, frequency response, phase response, etc.) which can be indirectly adjusted via effective values (e.g. type of fluid, flow rate, temperature, pressure, pipe material, etc.). The adjustability of the number and distribution of the frequencies transmitted on the device is also novel.

Description

Method and device for the electromagnetic treatment of fluids

The electromagnetic treatment of fluids is beginning to take hold. Of particular interest here are devices which can change the structure of the fluid (usually water) and thus also the solubility products of the poorly soluble salts contained therein. The results of research and practical tests in this area are continuously implemented in new devices.

State of the art

There are electromagnetic water treatment devices of very different designs and based on different treatment principles. In the following, devices of particular interest are those which generate a pulsating magnetic field by means of a current passed through one or more coils and thereby emit an electromagnetic wave into the fluid. Today you can find devices of the so-called sweep technology, wobble technology and resonance frequency technology. All these devices have one thing in common: they try to excite certain frequencies in a certain sequence in a certain frequency range. They differ in the way they do this.

Disadvantages of existing techniques and devices

The main disadvantage of all previous devices is their inability or limitation to adapt optimally to practical use. As a result, they remain unsuccessful in many applications. Usually, such devices offer the possibility of up to three manipulated variables, e.g.

- power and frequency band,

- water hardness and consumption or

- Set frequency, DC and AC field strength for a fixed waveform.

Now the practical case is usually more complex. One can differentiate between three groups of properties of practical cases, to which the device or its signal components should be able to adapt. The most important are:

1) Properties of the fluid:

- Fluid type (e.g. water, mud, milk, crude oil, etc.)

- additives, additives (e.g. silicates, phosphates, glucol, etc.)

- water hardness 2) Features of the application:

- temperature

- Print

- Consumption type (sporadicity)

- flow velocity (maximum, minimum)

3) Features of the installation:

- place of installation

- Pipe diameter under the coils

- Pipe material under the coils

- Pipe wall thickness under the coils

- cable length

- Spool dimension and number

- Number of support devices

There has never been a device that takes a large part of these parameters into account, so that the success of the previous devices was more or less a matter of chance, if not always an expert attended the installation.

Resonance frequency devices are e.g. suitable for high flow velocities and liquids with organic components. They are less suitable for low flow velocities or for cases in which a very high signal power is required, e.g. very hard drinking water, copper pipes, large pipe diameters, etc., since the many emitted frequencies are emitted at the same time and the performance per frequency is therefore low.

In contrast, the sweep technique is particularly suitable for flow velocities below 0.5m / sec, but not at all for higher flow velocities. The lack of adaptability is tried to compensate for the various previous techniques by using a device with higher performance. Ultimately, the number and distribution of the frequencies cannot be set on any of the previous devices.

solution

However, the problems described above can only be optimally solved if a device can be precisely adjusted to the various influencing factors by different signal components being set directly or indirectly on the device. The main independent signal components are - the number of active frequencies,

- the lower limit frequency,

- the upper limit frequency,

the respective amplitudes of the individual frequencies,

- the distribution of the individual frequencies in the band and

- The parameters for a continuous oscillation of the spectrum.

The result of the desired signal component setting is a certain, but not easily describable signal form. Maintaining a certain proportionality of the signal components to the set properties of the practical application is more important than generating an exactly desired signal form.

The aim and the new idea of the invention presented here is therefore to be able to set each of these signal components independently of one another on a single device. This can e.g. on adjustment buttons or by means of buttons (like a digital clock) either directly or in a user-friendly way by the user setting the above-mentioned influencing factors, which should be known to him or an installer. The number of influencing variables that can be set must be at least as large as the number of signal components above, because this is the only way to achieve an independent setting of the individual signal components (for example, you cannot build a tap that has a single screw that can only be screwed on and off) can, and at the same time require an independent setting of consumption quantity and temperature).

If, for example, the coils of an electromagnetic device for the treatment of a fluid, which can be influenced in the frequency range 0-12 kHz, are attached to an iron pipe, the frequency response corrections can be carried out based on the following two findings. Firstly, a normal iron pipe with a wall thickness of 3mm at 100Hz has an attenuation of -30dB and at 2kHz an attenuation of -90dB. As a result, the power transferred to the fluid from 1 kHz is ineffective and is therefore unnecessarily heated. In this case, frequencies above 2 kHz should be avoided. Second, a decrease in the frequency response of the iron pipe in lower frequencies from 100 Hz to 500 Hz, e.g. can be compensated with a signal with increasing frequency response and / or with additional frequencies in the range 300Hz-500Hz.
