Definitions

  • the present invention relates to a device for heating a liquid comprising an elongated heating element which extends in this liquid, in particular for the purpose of producing steam.
  • the vaporization of water is achieved by heating elements which extend into the water and which contain electrical heating resistors. In some installations, all the steam produced is used. The steam generators are therefore supplied continuously with the quantity of water required. In other installations, the steam produced is recycled in the form of condensate. However, taking into account the necessary leaks and purges and possibly a partial use of the vapor produced with lost fluid, it is in any case necessary to constantly replenish the generators with new water.
  • the main remedy used consists in adding water heaters or steam generators to the supply water using heating elements with high thermal flux very sensitive to the smallest deposits, chemical dispersants.
  • this remedy has the disadvantage of generating a high operating cost due mainly to the installation of accessories necessary for the continuous supply of these chemical dispersants with water and to the quantities of dispersants used linked to the high consumption. of water.
  • the present invention aims to remedy at least partially to the problem associated with the aforementioned deposits in a simple and inexpensive manner.
  • the device for heating a liquid which comprises an elongated heating element which extends in this liquid, with a view in particular to producing steam, is such that on this elongated heating element is disposed freely an anti-depositing means, in particular of tartar, comprising a succession of parts which are wound around the heating element and spaced in the longitudinal direction of the latter and which, under the effect of the movement of the liquid possibly charged with vapor and / or the formation of vapor bubbles on the peripheral surface of the heating element, moves relative to this surface, thus making it possible at least in part to avoid the deposit of solid materials, in particular tartar, on the element heating.
  • an anti-depositing means in particular of tartar
  • the above-mentioned anti-deposition means comprises at least one wire element wound in a helix around the above-mentioned elongated heating element.
  • the aforementioned anti-deposition means can be of circular section.
  • the aforementioned anti-deposition means may have at least one edge located on the side of the surface of the elongated heating element.
  • the aforementioned anti-deposition means may comprise at least one face inclined relative to the surface of the elongated element.
  • the aforementioned anti-deposition means is freely disposed between two stops fixed on the elongated heating element.
  • one of the ends of the aforementioned anti-deposition means is connected to the elongated heating element, its other end being free.
  • the anti-depositing means can be made of a spring material.
  • the above-mentioned elongated heating element can advantageously extend through a passage formed in the wall of a liquid reservoir, this passage being dimensioned so as to be capable of being traversed by said heating element equipped at its periphery with the aforementioned anti-deposition means.
  • the invention also relates to an elongated heating element with internal electrical resistance, equipped with an anti-deposition means according to any one of the above specificities.
  • a steam generator has been represented generally identified by the reference 1 which comprises a reservoir 2 having a cylindrical envelope 3, two radial walls of ends 4 and 5, a water supply conduit 6 provided at its lower part and a steam evacuation conduit 7 provided at its upper part.
  • an elongated heating element 8 which passes through and which is carried in a sealed manner by the radial partition 4.
  • This elongated heating element 8 is of circular section and contains an electrical resistance not shown capable of being connected to a electric power supply source by means of connection 9 provided at its end external to the tank 2.
  • the heating element 8 carries, near its free end, a ring 10 and, near the radial wall 4, a ring 11, these rings 10 and 11 being for example fixed by welding.
  • an anti-deposition means constituted in this example by a wire element 12 of circular section which is wound in a helix with regular or variable pitch around the heating element 8 and which is made of a spring material.
  • the turns of this spring 12 constitute a succession of parts which are wound around the heating element 8 and which are spaced in the longitudinal direction of the latter.
  • the inside diameter of this spring 12 can correspond substantially to the outside diameter of the heating element 8, but is preferably slightly greater. Its total length may correspond substantially to the distance between the abovementioned stops 10 and 11 but it is preferably slightly less. Thus, the spring 12 is freely mounted on the heating element 8.
  • the end wall 4 of the tank 2 has a circular passage 13 whose diameter is at least equal to the largest diameter of the spring 12 and stops 10 and 11, a conventional means 14 for example with rings allowing the fixing of the heating element 8 in this passage 13.
  • the tank 2 can be equipped in its lower part with several parallel heating elements mounted in the same way as the heating element 8 and equipped in the same way with an anti-deposit means 12 freely placed between two stops 10 and 11.
  • the anti-deposit means constituted by the spring 12 rests by its turns at different points on the heating element 8.
  • the heating element 8 is supplied with electrical energy and water is brought into the tank 2 through its supply duct 6 so that the water level in this tank is at above the heating element 8.
  • the turns anti-deposit means constituted by the spring 12 move relative to the peripheral surface of the heating element 8.
  • the turns perform, almost independently, reciprocating movements or radial and / or longitudinal and / or rotational beats which can be brutal and / or jerky.
  • the spring 12 thus stressed strikes the peripheral surface of the heating element 8 by producing shocks and / or rubs on the latter.
  • the heating element 8 may have a diameter of 19 mm.
  • the diameter of the wire constituting the spring 12 can be 1.5 mm.
  • the internal diameter of this spring can be 21 mm, thus leaving a radial clearance of 2 mm.
  • the pitch of its turns can be 11 mm, thus leaving a longitudinal space of 9.5 mm between successive turns, and its length can be 1500 mm for a distance between stops 10 and 11 of 1600 mm.
  • FIG. 2 differs from the previous one by the fact that the end turn 17 of this spring 16 is fixed to a ring 18 fixed on the heating element 15, the spring 16 being otherwise free.
  • the anti-deposition means is constituted by a wire 19 of square section, one of the angles of which is on the side of the peripheral surface of the heating element 20 so as to constitute an edge 21 going around this heating element, on either side of which extend faces 22 and 23 inclined in opposite directions relative to its peripheral surface.
  • This structure of the anti-deposit means 19 makes it possible to amplify the aforementioned movements of its turns and to cause improved scraping or scraping of the peripheral surface of the heating element 20.
  • an anti-deposit means 24 of very flat rectangular section which also has a scraping edge 25 and a main face 26 inclined relative to the peripheral surface of a heating element 27, thus promoting rotation of this anti-deposit means 24 or of its turns in one direction.
  • the anti-depositing means 28 shown in FIG. 5 differs from the anti-depositing element 19 shown in FIG. 3 only by the fact that it is of V-shaped section with two substantially equal branches and whose faces exterior faces the peripheral surface of a heating element 29 and inclined relative to the latter.
  • the anti-deposit element 30 is constructed from a wire of rectangular section wound around a heating element 31 like that of FIG. 4.
  • This wire 30 has side of this element 31 of zones 32 and 33 folded alternately on one side and the other so as to present successive faces 34 and 35 inclined alternately with respect to the peripheral surface of the heating element 31.
