Abstract
Description
La présente invention concerne un générateur inductif de vapeur, fluide et gaz chaud qui utilise l'énergie électrique pour le chauffage de fluide ou de gaz.The present invention relates to an inductive generator of steam, fluid and hot gas which uses electrical energy for heating fluid or gas.
Ce générateur est du type transformateur électrique comportant un enroulement primaire 6 alimenté en énergie électrique et couplé par un circuit magnétique au secondaire 8 qui est un tube coudé double enveloppe en court-circuit.This generator is of the electrical transformer type comprising a primary winding 6 supplied with electrical energy and coupled by a magnetic circuit to the secondary 8 which is a short-jacket bent tube.
L'enroulement secondaire 8 est donc du type double enveloppe séparé d'un fil conducteur 21 spiralé.The secondary winding 8 is therefore of the double jacket type separated from a spiral conductive wire 21.
Le fluide et le gaz à chauffer parcourt ce tube 8 et s'échauffe au contact des parois du tube 8,lui meme étant chauffé par les courants induits produits par le transformateur.The fluid and the gas to be heated pass through this tube 8 and heat up in contact with the walls of the tube 8, itself being heated by the induced currents produced by the transformer.
Cette invention se différencie des autres par son circuit secondaire.This invention differs from others by its secondary circuit.
Ce circuit secondaire est donc formé d'un tube coudé double enveloppe insérant entre les deux enveloppes (20,22) un fil conducteur spiralé 21 dont le pas des spires augmente réguliérement de l'entrée à la sortie du tube secondaire.This secondary circuit is therefore formed of a double envelope bent tube inserting between the two envelopes (20,22) a spiral conductive wire 21 whose pitch of the turns regularly increases from the entry to the exit of the secondary tube.
Ce qui permet une bien meilleure répartition des zones de chauffage et facilite la circulation du fluide ou du gaz de l'entrée vers la sortie. This allows a much better distribution of the heating zones and facilitates the circulation of the fluid or gas from the inlet to the outlet.
L'invention sera plus explicite à la vue des plans annexés.The invention will be more explicit from the view of the attached plans.
La figure 1 est une représentation schématique de l'invention
La figure 2 est une vue agrandie montrant en détail le circuit secondaire chauffant le fluide et le gaz.Figure 1 is a schematic representation of the invention
Figure 2 is an enlarged view showing in detail the secondary circuit heating the fluid and the gas.
On reconnait sur la figure 1 les éléments d'un transformateur électrique à savoir en 6 un enroulement formant le circuit primaire couplé, à un enroulement simple formant le secondaire, par un circuit magnétique 7 sur lequel 6 et 8 sont implantés.We recognize in Figure 1 the elements of an electrical transformer, namely at 6 a winding forming the primary circuit coupled to a single winding forming the secondary, by a magnetic circuit 7 on which 6 and 8 are installed.
L'enroulement primaire 6 est en cuivre ou aluminium,émaillé.The primary winding 6 is made of enameled copper or aluminum.
Le primaire 6 est bobiné sur un coté du circuit magnétique 7 du type des transformateurs dits "secs". The primary 6 is wound on one side of the magnetic circuit 7 of the type of so-called "dry" transformers.
L'enroulement primaire 6 est quand à lui relié soit directement sur un réseau 0 en courant alternatif basse tension via différents contacts de coupure,soit par l'intermédiaire d'un variateur de tention 5.The primary winding 6 is connected to it either directly on a low-voltage alternating current network 0 via different cut-off contacts, or by means of a voltage variator 5.
L'enroulement secondaire 8 est un tube conducteur coudé en court-circuit (détaillé fig. 2) dans lequel rentre le fluide et le gaz à chauffer et duquel ressortent le fluide et le gaz chauffés
Le tube 8 entoure le circuit magnétique à l'opposé du circuit primaire 7.The secondary winding 8 is a short-circuited elbow conducting tube (detailed in fig. 2) into which the fluid and the gas to be heated enter and from which the heated fluid and gas emerge.
The tube 8 surrounds the magnetic circuit opposite the primary circuit 7.
Un bouton marche-arret 1 est monté sur le primaire puis suivi d'un contact de demande de chauffe 2 suivi d'un contact de sécurité 3 de surchauffe,suivi d'un voyant 4 présence tension.An on-off button 1 is mounted on the primary then followed by a heating request contact 2 followed by a safety overheating contact 3, followed by a voltage presence indicator 4.
Un capteur de température 24 est lié au tube 8 et donc agit directement sur le contact 3 qui coupe l'alimentation du circuit primaire en cas de surchauffe du tube 8 et régule en tout ou rien.A temperature sensor 24 is linked to the tube 8 and therefore acts directly on the contact 3 which cuts the supply to the primary circuit in the event of the tube 8 overheating and regulates all or nothing.
Une électrovanne 9 permet le passage de fluide et de gaz à ltentrée du tube 8. Son ouverture est liée à la demande de vapeur de fluide et de gaz chaud. Sa fermeture se fait après temporisation,suite à une coupure du circuit primaire ou un arret de demande de vapeur,de fluide et de gaz chaud.A solenoid valve 9 allows the passage of fluid and gas at the inlet of the tube 8. Its opening is linked to the demand for fluid vapor and hot gas. It closes after a delay, following a cut in the primary circuit or a shutdown of demand for steam, fluid and hot gas.
En cas d'installation autonome il est possible d'adapter un réservoir 10 en amont de l'électrovanne 9. In the case of an autonomous installation, it is possible to adapt a reservoir 10 upstream of the solenoid valve 9.
On reconnait sur la figure 2 le détail du tube 8 formant le secondaire du générateur.We recognize in Figure 2 the detail of the tube 8 forming the secondary of the generator.
Ce tube est tout d' abord formé d'un premier tube 20 d'une longueur bien définie pour l'application. Sur ce tube 20 est spiralé un fil conducteur 21 d'un pas grandissant vers la sortie du tube 20 afin de mieux répartir le chauffage du tube et faciliter l'évacuation de la vapeur,du fluide et du gaz chaud. Ce fil 21 peut etre soudé à chaque extrémité du tube 20 et de place en place pour assurer son maintient sur le tube 20. Un tube 22 recouvre le tube 20 et le fil spiralé.This tube is firstly formed of a first tube 20 of a length well defined for the application. On this tube 20 is spiraled a conductive wire 21 of a growing pitch towards the outlet of the tube 20 in order to better distribute the heating of the tube and facilitate the evacuation of the vapor, the fluid and the hot gas. This wire 21 can be welded at each end of the tube 20 and from place to place to ensure its maintenance on the tube 20. A tube 22 covers the tube 20 and the coiled wire.
Un capteur de température 24 est lié au tube 22.A temperature sensor 24 is linked to the tube 22.
Une gaine isolante 23 recouvre le tube 22.An insulating sheath 23 covers the tube 22.
Aux extrémités du tube 22 sont soudés deux raccords filetés 25-27 afin de faciliter l'implantation de l'ensemble.At the ends of the tube 22 are welded two threaded connections 25-27 in order to facilitate the installation of the assembly.
Le tube une fois équipé est cintré en fonction du circuit magnétique 7
Une liaison électrique 26 est faite entre les deux extrémités du tube 22 afin de metre le tube en court-circuit.Once fitted, the tube is bent according to the magnetic circuit 7
An electrical connection 26 is made between the two ends of the tube 22 in order to short-circuit the tube.
Pour des raisons de sécurité il faudra relié le tube 23 à la masse de l'appareil qui sera reliée à la terre.For safety reasons, the tube 23 must be connected to the earth of the device which will be connected to earth.
Le tube complet 8 est implanté autour d'un coté du circuit magnétique 7 en formant le secondaire du générateur. Ce tube est traversé par un courant alternatif induit créant un échauffement du tube (effet Joule) qui par sa bonne conductivité chauffe gaz et fluide à l'intérieur. The complete tube 8 is installed around one side of the magnetic circuit 7, forming the secondary of the generator. This tube is crossed by an induced alternating current creating a heating of the tube (Joule effect) which by its good conductivity heats gas and fluid inside.
