Definitions

  • the present invention essentially relates to a device for heating industrial liquids in situ.
  • the object of the present invention is to remedy the above drawbacks in particular by proposing a new heating device which is somewhat independent of the tank containing the liquid to be heated, and has great flexibility of use.
  • the subject of the invention is a device for heating any liquid by the burnt gases produced in a combustion chamber associated with a burner, characterized in that the burner and its associated combustion chamber form a mobile and waterproof heating unit, immersible in the liquid to be heated.
  • the heating unit thus produced constitutes a compact and removable assembly which is versatile and whose maintenance is considerably easier compared to previously known installations and comprising for example a burner outside the tank containing the liquid to be heat.
  • the submersible heating device according to the invention can be compared for example to a compact immersion heater with gaseous fuel.
  • the above-mentioned heating unit constitutes a box, at least one of the walls of which is provided with pipes or the like opening out above the liquid level and allowing respectively the supply of fuel, the outlet burnt gases, and the passage of the electrical ignition and safety burner connections.
  • the walls of the box forming, the heating unit constitute as many exchange surfaces.
  • the part of the box forming the combustion chamber is crossed in leaktight fashion by one or more circulation channels, by thermosyphon, of the surrounding liquid.
  • the aforementioned combustion chamber comprises means, such as for example grates or the like, creating turbulences of hot gas preferably around the aforementioned channels.
  • the aforementioned box substantially has the shape of a parallelepiped comprising a premixing and fuel homogenization chamber, which is separated from the combustion chamber by a grid or the like for stabilizing the flame.
  • premix chamber contains one or more grids for distributing the fuel before combustion.
  • a heating device essentially comprises a compact heating assembly 1 which is in the form of a box 2, preferably parallelepipedal, and entirely submerged in the liquid to be heated 3.
  • This liquid can for example be an industrial liquid contained in a tank (not shown). We have only shown at 4 the level of this liquid 3 in FIG. 2.
  • the heating unit or box 2 has six walls forming as many exchange surfaces and one of which 2.a is provided with conduits opening above the level 4 of liquid 3, as can be seen in FIG. 2. More specifically, the supply of fuel gas-combustion air, in substantially stoichiometric quantity takes place through a line 5 opening into a chamber 6 for premixing and homogenizing the fuel, as can be seen better in FIGS. 2 and 3. Another conduit 7 visible in Figure 1 allows the passage of the electrical ignition and safety connections of the burner. Finally, the cold burnt gases are discharged through a third pipe 8 which opens into the combustion chamber 90
  • channels 10 can have any shape in cross section, for example circular or polygonal, as can be seen in FIG. 3. They allow the circulation, by thermosiphon, of the surrounding liquid 3 as shown by arrows in FIG. 2.
  • vertical channels 10 advantageously increase the external exchange surface formed by the walls of the box 2.
  • the exchange surface in question can be further increased by providing metallic fins or the like 11 around the channels 10, as shown for example in FIG. 6.
  • the part of the box 2 containing the flame and forming the combustion chamber 9 preferably comprises means creating turbulences of hot gas inside this chamber to give the heating unit 1 good performance with a minimum of space.
  • These means can be arbitrary and arranged in any way in the combustion chamber 9. Thus they can for example be constituted by grids 12 arranged around the channels 10, as seen in FIG. 5. Consequently, the grids 12 will favor the formation of jets of hot gas directed towards the exchange walls produced by the channels 10.
  • the premix chamber 6 advantageously contains one or more grids 13 arranged in an appropriate manner inside the latter so as to achieve an ideal distribution of the gaseous mixture arriving via line 5.
  • This grid 14 which is seen on a larger scale in FIG. 4 is preferably consisting of a metal plate pierced with one or more networks of holes 15, which plate is formed of several sheets, sheets, metallic fabrics, or the like 16 superimposed, assembled, and themselves pierced with holes, as for example described in French patent n ° 69 37574 belonging to the applicant .__ Such a grid 14 advantageously makes it possible to obtain a high combustion intensity which can lead to heating powers of up to 2 kW / cm 2 .
  • a gas burner with high combustion intensity has therefore been produced according to the invention and associated with a combustion chamber so as to form a very compact, removable, versatile heating unit which can very easily be immersed in a tank containing a liquid to heat whatever, using a winch for example.
  • the heating block according to the invention makes it possible to reach a heating power ranging from 1000 to 2000 kW / m 3 occupied, and that the yields obtained with this block are approximately 20% higher than those of the installations of liquid heating used so far.
  • the means 12 creating turbulence in the combustion chamber 9 can have any structure and arrangement inside thereof, as the number and structure of the distribution grids in the premix chamber 6 can also be any, and that one can also provide any number and any shape for the vertical channels 10 in the combustion chamber formed inside the metal box 2. Likewise, this box can have a shape other than parallelepiped.
