Abstract

Automatic modulation of the effect of a stable electromagnetic field on a fluid whose instantaneous flow rate is very variable, by instantaneous modification of the geometry (dimensions, shapes) of chambers (5) in which the fluid is subjected to the electromagnetic fluxes (4). The devices according to the invention include movable and/or elastic and/or malleable components which move and/or are deformed as a function of the differential of the pressure of the fluid, thus instantly adapting the volume of the treatment chambers (5). The apparatus provided with these automatic regulation devices will have a constant efficiency because the essential parameters of the treatment (fluid velocity and time of exposure to the fields) will be practically constant regardless of the instantaneous flow rate. In addition to the treatment of hard water, these regulators can be adopted in applications such as gas distribution, UV radiation, heat exchanges etc.

Description

La présente invention a pour objectif de moduler automatiquement l'effet d'un champ de forces constant sur un fluide en mouvement, quel que soit le débit instantané du dit fluide.The present invention aims to automatically modulate the effect of a constant force field on a moving fluid, regardless of the instantaneous flow rate of said fluid.

On sait que le traitement d'un fluide en mouvement par un procédé physique (champs électro-magnétiques, rayonnements,...) exige que le flux appliqué soit strictement fonction de certains paramètres tels que la vitesse du fluide et son temps d'exposition.We know that the treatment of a moving fluid by a physical process (electromagnetic fields, radiation, ...) requires that the applied flux be strictly a function of certain parameters such as the speed of the fluid and its exposure time. .

Or, si le flux est constant par définition (champs généré par des aimants permanents par exemple), il est impératif, pour obtenir une efficacité optimale, que les paramètres vus plus haut (vitesse et temps d'exposition) soient stabilisés, quel que soit 1E débit instantané du fluide a traiter.However, if the flux is constant by definition (fields generated by permanent magnets for example), it is imperative, to obtain optimal efficiency, that the parameters seen above (speed and exposure time) be stabilized, whatever 1E instantaneous flow of the fluid to be treated.

Ld présente invention a pour objectif précisément de rendr-e ces paramètres constants par une adaptation automatique du volume des chambres de traitement (5) dans lesquelles s'exercent ces champs électriques et/ou magnétiques (4). The present invention aims precisely to make these parameters constant by an automatic adaptation of the volume of the treatment chambers (5) in which these electric and / or magnetic fields (4) are exerted.

La géométrie variable des chambres de traitement sera obtenue grâce à la déformation de matériaux élastiques (6) et/ou déformation des entrefers (7) et/ou déplacement de tiroirs mobiles (10).The variable geometry of the treatment chambers will be obtained by the deformation of elastic materials (6) and / or deformation of the air gaps (7) and / or displacement of mobile drawers (10).

Sera décrit ci-après un appareil anti-incrustation d'une eau chargée de carbonates de calcium (eau dure) qui utilise des champs électriques et/ou magnétiques, par définition à flux constants.An anti-encrustation device for water loaded with calcium carbonates (hard water) which uses electric and / or magnetic fields, by definition with constant flux, will be described below.

Mais 1 'extrapolation d tout autre appareil utilisant des rayonne- ments (U.V. par exemple) est tout à fait possible. However, extrapolation from any other device using radiation (UV, for example) is entirely possible.

Ce type d'appareil comprend 4 parties@ * A ) LE COFFRET OU LE TUBE EXTERIEUR (1):
Ses caractéristiques sont fonction du fluide qui doit être traité (température, composition chimique, pression,...) et il s'installe de manière très classique dans le réseau du fluide.This type of device includes 4 parts @ * A) THE CASE OR THE OUTER TUBE (1):
Its characteristics are a function of the fluid to be treated (temperature, chemical composition, pressure, ...) and it is installed very conventionally in the fluid network.

* B ) LE CORPS PRINCIPAL (2) :
Usiné dans un matériau amagnétique et diélectrique, il contient les dispositifs vus en C & D ci-après.* B) THE MAIN BODY (2):
Machined from a non-magnetic and dielectric material, it contains the devices seen in C & D below.

* C ) LE GENERATEUR DE CHAMP A GEOMETRIE VARIABLE (3) :
Oue le champ soit électrique ou magnétique, le générateur de champ une géométrie varidble au niveau de l'entrefer (7).* C) THE VARIABLE GEOMETRY FIELD GENERATOR (3):
Whether the field is electric or magnetic, the field generator has a variable geometry at the air gap (7).

Selon une première réalisation de l'invention (fig #),les éléments du générateur (3). sont logés dans 2 parties du corps principal (2) dont l'une est fixe et l'autre est un tiroir mobile (10) repoussé lement repousse par un ressort de rappel (11).According to a first embodiment of the invention (fig #), the elements of the generator (3). are housed in 2 parts of the main body (2), one of which is fixed and the other is a movable drawer (10) which is pushed back by a return spring (11).

Une tige rigide (14) reliée au tiroir permet de connaître sa position, éventuellement de conduire le courant etiou de déclencher d'autresdispositifs (action sur intensité du courant par exemple)
Selon une seconde réalisation de I i nveni on (fig #),les pi polaires (8) des aimants ont la faculté de se déforme@. A rigid rod (14) connected to the drawer allows to know its position, possibly to conduct the current and / or to trigger other devices (action on current intensity for example)
According to a second embodiment of I i nveni on (fig #), the pole pieces (8) of the magnets have the ability to deform @.

Constituées de poches souples (12), remplies de limaille d'un m@té riau ferro-magnétique, elles suivent les déformations des chambres tout en conduisant de manière optimale les lignes de farce du champ (4) grâce à la perméabilité spécifique du matériau.Made up of flexible pockets (12), filled with filings of a ferro-magnetic material, they follow the deformations of the chambers while optimally conducting the filling lines of the field (4) thanks to the specific permeability of the material .

Des volets rabattables (13) ou des tiroirs mobiles (10) repoussés par des ressorts (11), adaptent immédiatement et automatiquement la forme de ces poches déformables (12) à celle des chambres (5).Folding flaps (13) or movable drawers (10) pushed back by springs (11), immediately and automatically adapt the shape of these deformable pockets (12) to that of the chambers (5).

* D ) LES CHAMBRES DE TRAITEMENT (5):
Ce sont tout simplement les volumes dans lesquels circule le fluide à traiter et où s'exercent les champs électro-magnétiques (4).* D) TREATMENT ROOMS (5):
These are quite simply the volumes in which the fluid to be treated circulates and where the electromagnetic fields are exerted (4).

La caractéristique essentielle de ces chambres de traitement (5) est la variablité de leurs formes et de leur volume en fonction dit débit instantané de l'installation: pour un débit nul, le volume est nul ou minimal.The essential characteristic of these treatment chambers (5) is the variability of their shapes and their volume as a function of said instantaneous flow of the installation: for a zero flow, the volume is zero or minimal.

* Selon une première réalisation de l'invention (fig #), l'appareil utilisant un champ magnétique comprend un ou plusieurs. aimants permanents, coiffés de pièces polaires (8), figées ou déformables (12) dont les formes et disposition dépendent des lignes de force que l'on veut obtenir en fonction du débit instantané .* According to a first embodiment of the invention (fig #), the device using a magnetic field comprises one or more. permanent magnets, capped with pole pieces (8), fixed or deformable (12), the shapes and arrangement of which depend on the lines of force which it is desired to obtain as a function of the instantaneous flow.

Le passage du flux (4) à travers tous matériaux amagnétiques pérmet l'emploi d'enveloppes élastiques isolantes ou de tuyaux plats o. cylindriques (h), pour constituer les chambres (5).The passage of the flux (4) through all non-magnetic materials allows the use of insulating elastic envelopes or flat pipes o. cylindrical (h), to form the chambers (5).

Des pièces élastiques compressibles (9) peuvent accompagner la déformation des membranes élastiques (6).Elastic compressible parts (9) can accompany the deformation of the elastic membranes (6).

Des dispositifs classiques de réglage permettent d'adapter la tension des enveloppes èlastiques (6) à la pression du réseau. t Selon une seconde réalisation (fig #),utilisant un champ blpr- trique (4), anode et la cathode sont constituées de lamelles articulées (15) fixées à l'intérieur de 2 membranes souples imperméables qui constitue un canal dans lequel circule le fluide.Conventional adjustment devices make it possible to adapt the tension of the elastic casings (6) to the network pressure. t According to a second embodiment (fig #), using a brick field (4), the anode and the cathode consist of articulated lamellae (15) fixed inside 2 flexible impermeable membranes which constitute a channel in which the fluid.

Plaquées sur les 2 parois opposées de la chambre (5), ces plaque articulées ont donc la faculté de suivre les déformations de la dite chambre en fonction du débit instantané. Plated on the 2 opposite walls of the chamber (5), these hinged plates therefore have the ability to follow the deformations of said chamber as a function of the instantaneous flow.

Les parois opposées de la chambre étant inélastiques, des ressorts de rappel (11) ont pour fonction de les tendre de manière permanen- te, quel que soit le débit. The opposite walls of the chamber being inelastic, return springs (11) have the function of tensioning them permanently, whatever the flow rate.
