Description

The present invention relates to a method of treating rising humidity in walls, as well as an electronic device for the implementation of this method.

This humidity, which comes from the ground, sees the action of the phenomena of osmosis and capillarity relayed and largely amplified by the appearance of potential differences inside the walls, creating a constant pile effect.

The present invention aims to interrupt this stack effect and, thereby, the rise of humidity in the walls by reversing the potential differences and closing the capillaries of the wall.

To do this, holes or grooves are made in the walls, into which are introduced assemblies in the form of bars, tubes or metal beams. However, according to the Coulomb principle, any conductive body brought into contact with the ground is negatively charged.

In fact, in constructions, due to the presence of numerous electrical circuits, household or audiovisual appliances, there are so-called "stray currents", capable of reversing the. polarity of the bars, currents which are at the origin of failures in the processes currently used. Likewise, the movement of vehicles (made of a large number of more or less magnetized pieces of steel) in the Earth's magnetic field inevitably produces induced currents (so-called eddy currents) which in turn generate variable magnetic fields.

In the document "Elektrophysikalische Verfahren zur Mauertrockenlegung, Teil 1", electrochemical methods are used, based on the treatment of the rising humidity of a wall by the passage of a direct current using metallic electrodes in the form bars, tubes or bundles, introduced into the wall, and possibly sealed using specific mortars, aiming either to cancel or even to reverse the potential difference existing in the wall, and thus the current of responsible solvated ions water transport, or to seal the capillaries using a sealing material in the form of powder, the grains of which are diffused in the wall. The metal electrodes are then connected to the outside of the wall in order to form a closed electrical circuit, the wall constituting a part of this electrical circuit.

But these processes do not offer a lasting solution over time.

Indeed, in the case of the potential reversal in the wall, the user must continually supply energy to maintain the process. This involves considerable expenditure. In addition, the cancellation or inversion of potential necessarily leads either to the dissolution of one of the two electrodes by electrolysis, or to a deposit of insulating oxides on the two electrodes and therefore to an interruption of the process.

If the capillaries are blocked with a sealing material, it is impossible to completely suppress the rise in humidity in the wall, the stack effect not being interrupted. On the other hand, this leads to a large storage of water in the lower parts of the wall, and therefore to an accelerated decay of the foundations due to the retention of water at this level.

The problem posed by the present invention therefore consists in devising a method for treating the rising humidity in the walls using electrodes, in the form of bars, tubes or bundles, introduced into orifices formed in said walls, simultaneously realizing, on the one hand, the rapid obturation of the capillaries of said walls and, on the other hand, the elimination, in the long term, of the electric pump effect, mainly responsible for the rise of humidity in the walls, without having to continually supply energy and without the electrodes oxidizing or disintegrating, and without moisture accumulating in the foundations, so as to result in a lasting drying of said walls.

This problem is precisely resolved by the process which is the subject of the invention, a process characterized in that it mainly comprises two distinct treatment phases, namely, on the one hand, an energy supply phase consisting, after having added a catalysis element in the orifices in addition to the bars, tubes or beams, to send electrical pulses, supplied by an electronic circuit, on said tubes, bars or beams, thus achieving, simultaneously, on the one hand, an accumulation of electrostatic charges at the level of the bars, tubes or beams, and, on the other hand, thanks to a phenomenon of resonance of said electronic circuit with the proper internal circuit of the wall, a polarization at the level of the intracapillary electrolyte of the wall, resulting in a deposit of insoluble silico-calcium salts on the walls of the capillaries of the foundations, and to carry out measurements of control of the humidity rate and, on the other hand, an electro phase tatic consisting, when the desired degree of drying of the wall is reached, to disconnect the electronic circuit, then to plug the holes of drilling so as to seal the bars, tubes or bundles, thus loaded in the wall, thus allowing the electrostatic effect of the bars, tubes or beams to develop, and to the drying of the wall to continue by the rapid elimination of the remaining water by the natural ways and by the suppression, in the long term of the pump effect electric, due to the permanent elimination of the reverse polarity, responsible for the rise of humidity in the walls.

In accordance with the invention, the method of treating rising humidity in the walls consists, in particular, in previously drilling at least one orifice in the said walls, in introducing at least one tube, bar or metallic beam therein, the said method being characterized in that it mainly comprises two distinct treatment phases, namely, on the one hand, an energy supply phase consisting, after having added a catalysis element in the orifices 6 in addition to the bars, tubes or beams 7, to send electrical pulses, supplied by an electronic circuit 12, onto said tubes, bars or beams 7, thus simultaneously producing, on the one hand, an accumulation of electrostatic charges at the level of bars, tubes or beams 7 , and, on the other hand, thanks to a phenomenon of resonance of said electronic circuit 12 with the proper internal circuit of the wall 3, a polarization at the level of the intracapillary electrolyte of the wall, resulting t depositing insoluble silico-calcium salts on the walls of the capillaries of the foundations, and carrying out measurements to control the humidity level 4 and, on the other hand, an electrostatic phase consisting, when the desired degree of drying of the wall 3 is reached, disconnecting the electronic circuit 12, then plugging the holes 6 for drilling so as to seal the bars, tubes or bundles 7, thus loaded, in the wall 3, thus allowing the electrostatic effect of the bars, tubes or bundles 7 to develop, and to the drying of wall 3 to continue by the rapid elimination of the remaining water by natural means and by the elimination, in the long term, of the electric pump effect, of made of the durable elimination of reverse polarity 5, responsible for the rise of humidity 4 in the walls 3.

As shown in FIGS. 5 and 8 of the appended drawings, the process which is the subject of the invention consists, firstly, in implanting obliquely or vertically a series of bars, tubes or bundles 7 in a wall 3 at calculated distances to allow field forces to be recovered, these elements 7 being connected to the electronic circuit 12 pulse generator via a power supply box 13 for the duration of the energy supply phase, and disconnected during the electrostatic phase.

According to another characteristic of the invention, there is introduced between the bars, tubes or bundles 7 and the walls of the corresponding orifices 6, drilled in the wall 3, a catalysis element for the intracapillary physico-chemical reaction for closing the pores. , consisting of a powder formed from copper metal in very fine particles, zeolite and oxylith, if local conditions require it.

According to another characteristic of the invention, the electrostatic phase mainly consists in disconnecting the bars, tubes or bundles 7 from the electronic circuit 12 and in maintaining the potentials in the wall 3 by the electrostatic action of the bars, tubes. or bundles 7.

The invention also relates to an electronic device for implementing the method, comprising metal electrodes in the form of bars, tubes or bundles, introduced into the wall to be dried, possibly sealed using specific mortars, and connected together outside the wall to form a closed electrical circuit, characterized in that said bars, tubes or bundles are connected together outside the wall by means of an electronic generator 12 pulse generator and are constituted, as shown in FIG. 4 of the accompanying drawings, by a ferrite, nickel or lithium alloy, or by other alloys such as, in particular, iron-manganese-zinc with large crystals, or copper-zinc- arsenic, or copper-nickel 10 Fe 1 Mn, or else copper-nickel 30 Fe 2 Mn2, said tubes, bars or bundles 7 being covered with surface treatment 11, with a dielectric 8, preferably PVC, and em each, in their upper parts, in a cylinder or a coil of copper wires 9, which are partially insulated by a layer of the same dielectric 8, preferably PVC, said tubes, bars or bundles 7 acting as capacitors , once inserted in the wall 3.

According to the invention, and as shown in Figure 6 of the accompanying drawings, the electronic circuit 12 comprises a step-down transformer 17, connected to the mains by means of a switch 15 and a fuse 16, supplying a diode bridge 18, one output of which is earthed 26, and the other of which is connected to a circuit formed by three resistors 19, 20, 24, one of which 19 constitutes an intensity regulator, as well as a shunt 25 and a control ammeter 22, two light-emitting diodes 21, 23 controlling the balance of said electronic circuit 12.

According to a characteristic of the invention, the electronic circuit 12 generates pulses of positive polarity, at a variable voltage, suitable under local conditions, and from 5 to 15 milli-amperes, at a frequency of 100 Hertz for a tube, bar or beam 7, depending on the set of diodes 18, each bar, tube or beam 7 being supplied via a diode 29, connected in series.

In accordance with Figures 4 and 5 of the accompanying drawings, the diode 29 is located at the top of each bar, tube or bundle 7, to electrically balance the entire installation of the system, according to the evolution of the resistivity of the wall 3 during the energy supply phase of the process, the supply taking place in series.

The study of the electrostatic actions exerted at great distance by a distribution of charges thus led us to use for the bars a doping, so as to obtain electrons weakly bonded.

  in solid bars, tubes or bundles. Alloy bars, tubes or bundles have undergone a surface treatment and are covered with a dielectric which is often polyvinyl chloride. The upper part of the bar is inserted inside a cylinder or a coil of wire of the same metal. This cylinder or the coil of wire is partially covered with the same dielectric as the bar, and fed through a diode for balancing.

It was necessary, in the present case, to thus form a capacitor so that an appreciable part of the field forces is directed along the layer of dielectric and not perpendicular to this one, in the upper part of the bar.

The electromagnetic field obtained makes it possible to implement an important ionic drive process, for which the process comprises two phases.

1) An energy supply phase

The principle is to send pulses under a variable voltage, adapted to local conditions, of positive polarity, under an amperage of 5 to 15 milli-amperes (depending on the materials of the wall) at a frequency of 100 Hertz.

To do this, we use a 220-volt transformer supplied by a switch and a fuse. The secondary is connected to four diodes connected on the one hand to earth and on the other hand to a circuit comprising three resistors R1, Rx and R2 and to a circuit for a control ammeter. Rx constitutes the intensity regulator. Two light emitting diodes control the balance of the system.

All of these elements therefore constitute an electronic pulse generator circuit.

We know that a polarization is foreseeable in a system of electrolytes in solution when we are able to exert, using a capacitor of sufficiently high capacity and charge voltage, "direct information ". One can thus obtain a primer of crystallization inside the capillaries of the wall.

In the process this effect is obtained in the following way: it is well known (Electrophysikalische Verfahren zur Mauertrockenlegung. Teil 1 that the walls behave, from the electrical point of view, like a resistance-capacitor circuit. The device located at the top bars, (tubes or beams) behaves like a capacitor charged by the pulses at 100 Hz of the electronic generator circuit. This capacitor is discharged in the circuit of the wall, which has the property to vary in resistance and in capacity in time, depending on the condition of the electrolytes in the wall.

At different times of these variations, the discharges from the bar will find themselves in resonance (like an Oudin resonator) with the circuit of the wall. A high charge voltage is thus obtained, which is the source of the polarization and crystallization phenomena at the level of the intracapillary electrolyte.

At the beginning the discharge of the capacitor is oscillatory, because the resistance is weak and the self notable and we are in the conditions of polarization and crystallization. At the end of some time we are in the conditions of a quasi-continuous discharge which favors, around the primer produced by the crystal, the deposition of insoluble amorphous salts in the formation of which the copper ions released from electrolysis partial of the copper cylinder (or coil), or of the electrolysis of a copper powder in the presence of zeolite, play the role of catalyst. The powder is introduced into the hole when the bar is placed in the wall.

The zeolite activates the catalyst by the well-known phenomenon of intercalation in a lamellar silicate. If necessary or add oxylithe to provide nascent oxygen on contact with the wall water to avoid the accumulation of hydrogen coming from the water molecules which will have undergone electrolysis.

Obtaining the obturation in a few weeks of the majority of the capillary pores of the wall.

Walls in direct contact with a liquid sheet (Venice, Florence, etc.) require another electronic circuit to obtain the above-mentioned result. This additional circuit is, by consti kills a multivibrator whose frequency and duty cycle are automatically adjusted after initial calibration. It is supplied with a continuous voltage (conventional power supply) and enables the bars to be supplied with an intensity of 5 mA to 1.5 A; it is thus complementary to the electronic pulse generator circuit.

It constitutes an astable oscillator, which makes it possible to maintain the state of resonance with the proper circuit of the wall.

The load resistance, as well as the "parasitic capacity" offered by the wall give us the first element of the oscillator as the load resistance of the transistor T2- The transistor T1 will have its load adjusted by the resistance R1 so as to return the shape starting wave as symmetrical as possible (duty cycle 50/50, in rectangular form).

The transistors T1 and T2 being correctly polarized by the basic resistors RG1 and RG2, it suffices to react the astable oscillator by the capacitors C1 and C2. The system therefore enters an oscillation tuned to a frequency determined by the aircraft according to the resistivity on the wall.

RL is the resistance limiting the starting intensity at the start of the drying and also depending on the number of bars, the capacitance C 44 ensures decoupling on the supply of the transistors.

The LED circuit consists of the capacitor C3, the resistor R3 and the diode D3, it is only used to visualize that the device is oscillating correctly. Indeed, in the absence of oscillations, the capacitor C3 is not conductive and, therefore, does not supply the LED diode, R3 serving to limit the current in the diode.

What will happen in time? As the wall is treated, the resistance of the bars (RX) and the parasitic capacity (CX) of the bars will change in value, i.e. RX will see its values increase and CX its capacity will decrease . The time constant offered by RX + C2 will change, only the time constant C1 adjusted with R1 will remain constant. From this fiat the frequency of the oscillator will slide towards values lower than those of the starting point as well as the duty cycle which will decrease in the positive values.

In the event of total drying with a very high value of RX, the oscillator can stop completely.

Thus is maintained the agreement between the astable oscillator and the internal circuit + own capacity of the wall, and this continuous resonance makes it possible to maintain the high voltages necessary for a rapid blocking of the capillaries in the difficult conditions encountered in the wall near the sheet. of water, as in old walls, thick and very humid. An electric field of sufficient intensity to overcome the Schottky effect (which tends to keep the electrons trapped in the metal) thus allows the release of the easily mobilizable electrons from the metal. These electrons will meet the valences of the electrolyte solution of the wall and cancel the effects of the difference in primitive potential of the wall.

The pulses sent allow the accumulation of electrostatic charges in the dielectric of the bars, producing a strong movement of the solvated ions (therefore of their crown of dipolar water molecules) towards the evaporation surfaces of the wall. An inversion of the updraft inside the capillaries is also created by an identical phenomenon. Thus an efficient water transport which accelerates the drying of the wall is put in place.

The process is kept energized long enough for drying to become evident through control measures. Then the external current source is disconnected. We then go to the

2) Electrostatic phase

Passively, due to the structure of the bars, a potential difference is established, which can reach and exceed 800 millivolts, and which maintains the inversion which made it possible to stop the ascent of the water.

However, this passive phase of the process is essentially linked to electrostatics. Indeed, the friction of the ions in movement against the dielectric (PVC) creates an accumulation of static charges on this synthetic maintenance. The surface treatment maintains the electrostatic balance of the tube, bar on beam, and, therefore, the charges remain superficial and accumulate on the dielectric. The maximum electromagnetic field of the bars, tubes or beams is thus obtained.

The bars are introduced into the walls according to precise data calculated to ensure an efficient and gap-free recovery of their radial radiation. The process is likely to retain its strong activity beyond the ten-year period, the bars being insensitive to electrolysis.
