Definitions
- the present invention relates to an assisted regulation method of the hydrometry rate of a medium chosen under the action of an electric current.
- This process consists in applying a continuous unidirectional electric field between two electrodes.
- Patent F 2438122 for example, relates to a method which promotes the insertion of a stake into the ground having a sheet of water above the surface.
- This pile has an electrically conductive coating connected to the bottom thereof, a source of electrical energy isolated and connected between the negative terminal of this energy source and the conductive coating, a second electrical conductor connected to the positive terminal of the power source and placed in the water down along the outside of the stake so that friction between the stake and the ground is reduced, making it easier to drive the stake through the ground.
- the present invention concerning the assisted regulation of the hydrometry rate of a medium chosen under the action of an electric current finds a particularly effective application in the fields of construction and agriculture.
- Tests were carried out in the laboratory on terracotta samples, quarry stones and reinforced concrete blocks.
- a unidirectional electric field is then applied between the two electrodes placed at the non-submerged vertical ends of each sample by reversing the polarities alternately.
- the electrodes successively playing the role of anode and cathode.
- the inversion of sequential polarity of the electrodes has the effect of first disturbing the voltage existing between the initial polarities at the base of the sample and at its top, then gradually it reduces and cancels this voltage. This results in the disappearance of all the phenomena and reactions linked to the migration of water in the sample.
- the dehydration of the treated medium then taking place by capillary action towards the surfaces of evaporation.
- a humidity measurement probe placed in the material previously connected to an electronic central unit connected to the energy source. Once the hydrometric rate has been reached, the energy source ceases to act. It is the same in the case where water returns to the material, the measurement probe signals this to the central unit which starts the energy source which emits the electric field in the medium to be treated.
- the present invention eliminates these phenomena and its implementation can be done just after the pouring of the reinforced concrete or later in order to catch up with the disorders which would start to appear.
- the energy source diffuses its specific electric field by the electrodes inserted in the concrete but one can also use like electrode the metallic reinforcement of the concrete since the intensity remains weak in order to not not jeopardize the life of the scrap reinforcing the material.
- a humidity measurement probe is connected to an electronic control unit which stops the treatment, once the chosen hydrometry rate reached, leaving the plant on alert. Temperature differences may appear, these influence the speed of migration of the liquid in the target medium.
- the thermodynamic equilibrium fluctuates according to the interaction of electrons and protons representing preponderant thermal oscillatory movements which disturb the electrical stresses.
- the electronic control unit takes account of the conductivity differences that each medium may have.
- the voltage and intensity emitted are appropriate so that the electric field remains effective in all cases encountered.
- the present invention finds application in the context of agriculture.
- the electric field is applied to attract water from the deeper layers of the soil.
- the water travels osmotically to the electrode placed the least deeply in the ground. This is possible only in the case where the zeta potential is negative, in the opposite case, an inversion of the polarities, controlled by the electronic central unit at the energy source makes it possible to obtain the desired result.
- control unit automatically increases the intensity to compensate for the additional workload.
- the solid matter in contact with water does not have a surface charge.
- a potential difference is applied between the high and low electrodes placed in the cultivation soil, no movement of water occurs. If one wants to dry the medium this is possible in the present invention by diffusing a unidirectional electric field drawn by a single electrode. The operating process takes place in the earth as in the experiment previously described on the samples of terracotta, quarry stones and concrete; it dries quickly after each atmospheric precipitation.
- the location of the measurement probes determines the area treated and regulated by the electronic control unit, this does not prevent the process from being effective beyond the chosen area.
- the arrangement of the probes and electrodes is specific in order to optimize the desired result case by case.
- the frequency of electrical drainage depends on the hydrometric rate to be reached but also on the nature of the land, the different regions and seasons crossed.
