  • a computer not shown in the figures
  • the device (1) comprises a gas outlet duct (1.2), which is arranged at the top of the shell (1.1).

  • the device (1) additionally comprises an electrolyte inlet duct (1.3), which also runs into the lateral wall (1.12) of the shell (1.1), between the gas outlet duct (1.2) and a level of electrolyte contained in the cavity (1.11).
  • the electrolyte inlet duct (1.3) could be adapted to limit the level of electrolyte contained in the cavity (1.11), in other words, the lower edge of the electrolyte inlet duct (1.3) defines a maximum electrolyte level in the cavity (1.11).
  • the electrolyte inlet duct (1.3) prevents said maximum electrolyte level from being exceeded when filling the cavity (1.11) with electrolyte.
  • the electrolyte inlet duct (1.3) additionally prevents electrolyte splashes from reaching the gas outlet duct (1.2), which are produced with the bubbling exit of the gas from within the electrolyte during the water electrolysis reaction.
  • a primary condensation chamber (1.112) is also formed between the electrolyte inlet duct (1.3) and the gas outlet duct (1.2), which is not involved in the electrolysis.
  • the primary condensation chamber (1.112) is an empty space filled with air where the first condensation of the water vapour that accompanies the generated gases takes place, gases which, being in contact with the steel disc (1.14), or with the portion of the lateral wall (1.12) corresponding to the primary condensation chamber (1.112) formed, part of the water vapour that accompanies the gases condenses and drains down said portion of the lateral wall (1.12) towards the electrolyte, while the rest of its composition leaves the cavity (1.11) through the gas outlet duct (1.2).
  • the electrolyte inlet duct (1.3) protrudes from the lateral wall (1.12), as a sill, towards the cavity (1.11). It is thus achieved that the condensates that drain down the portion of the lateral wall (1.12) corresponding to the primary condensation chamber (1.112) do not go into said ducts (1.2, 1.3), going back into the electrolyte contained in the cavity (1.11).
  • the base (1.13) of the shell (1.1) and the base (1.61) of the plate (1.6) are fastened on a centring plate (1.7) made of insulating material.
  • This plate (1.7) is called a centring plate because one of its functions is to centre the plate (1.6) with respect to the lateral wall (1.12) of the shell (1.1).
  • the centring plate (1.7) could be made of nylon or Teflon, depending on the conditions and power of the device (1), Teflon being used when very high performance is required.
  • the bases (1.13, 1.61) are fastened to the centring plate (1.7) by means of bolts (7) that go through the latter, to which respective washers (8) and nuts (9) are screwed to carry out said fastening.
  • a silicone sealing sheet (1.9) could be arranged between the bases (1.13, 1.61), of the shell (1.1) and of the plate (1.6), and the centring plate (1.7).
  • the bases (1.13, 1.61) on the centring plate (1.7) are covered with an insulation layer (1.8) made of an inert material not taking part in an electrolysis reaction, forming a bottom (1.111) of the cavity (1.11).
  • the insulation layer (1.8) could be made of bi-component epoxy resin.
  • the insulation layer (1.8), made of an inert material not taking part in an electrolysis reaction, forming the bottom (1.111) of the cavity (1.11) extends between 10 and 20 cm over a lower portion (1.62) of the plate (1.6), so that the lower portion (1.62) of the plate (1.6) and the bottom (1.111) of the cavity (1.11) form a cold chamber (1.113), which provides thermal and corrosive protection to the connection between the bases (1.13, 1.61), the shell (1.1) and the plate (1.6), and the centring plate (1.7).
  • the cold chamber (1.113), formed in the lower part of the cavity (1.1), constitutes a "dead” or unreactive space, that is, without electrolysis reaction, proportional to the length of the lower portion (1.62) of the plate (1.6) and the bottom (1.111) of the cavity (1.11), filled with cold electrolyte.
  • said cold chamber (1.113) makes it possible to have two different densities and two very different thermal levels in a single liquid, that is, in the electrolyte contained in the cavity (1.11) of the shell (1.1).
  • This particular design of the device (1) and combination of materials of its components allows the electrical connection of its anode (1.42) through the lower part of the device (1) and avoids exposing the connections and delicate materials to very sudden thermal changes, thus prolonging the service life of the device (1), protecting the welding areas, joints and bolts, silicone gaskets, electrical power cables, etc.
  • the cold chamber (1.113) is not only used to protect said elements, but also, it is easier to keep the device (1) hermetic in its lower part than in its upper part, that is, it is easier to retain water (the electrolyte) than to retain hydrogen (H 2 ).
  • a design of a device is achieved that, by controlling the voltage, provides resistance to temperature, corrosion pressure and an anode design that wears out its service life before the surrounding cathode does.
  • the main components of the device can be manufactured from ANSI 316 STEEL, enhancing the safety and sustainability thereof.
  • the system for generating oxyhydrogen gas also an object of the invention, comprises at least one device (1) as that described above, and a direct current source (2), with respective positive (2.1) and negative (2.2) terminals connected to the anode (1.42) and to the cathode (1.41) of the electrode means (1.4) of the device (1).
  • the system comprises a set of devices (1) arranged in series, obviously with a view to producing a higher flow rate of oxyhydrogen gas (HHO).
  • the negative terminal (2.2) of the direct current source (2) is connected to the cathode (1.41) of the last of the devices (1) in the set, the cathode (1.41) of the rest of the devices (1) being connected to the anode (1.42) of the next device (1) in the set, and the positive terminal (2.1) of the direct current source (2) being connected to the anode (1.42) of the first device (1) in the set, thus, its connection in series is possible.
  • the system comprises condensation means (3), which are arranged downstream of the gas outlet duct (1.2) of the device (1), or of the respective gas outlet ducts (1.2) of the devices (1) that form the set of the embodiment shown in Figure 3 .
  • each gas outlet duct (1.2) of the devices (1) be in fluid communication with the condensation means (3) through a collector duct (4), where the collector duct (4) is made of a non-metallic or electrically non-conductive material.
  • the condensation means (3) comprise a coil section (3.1).
  • the condensation means (3) comprise a fan (3.4) that generates an air flow over the coil section (3.1), which favours the condensation of the water vapour that accompanies the oxyhydrogen gas (HHO) running through said coil section (3.1).
  • HHO oxyhydrogen gas
  • the condensation means (3) comprise a condensate chamber (3.2), which is connected to an outlet (3.11) of the coil section (3.1) and arranged above said coil section (3.1).
  • the condensation means (3) comprise a silica filter (3.3), connected to an outlet (3.21) of the condensate chamber (3.2) and arranged above said condensate chamber (3.2).
  • the silica filter (3.3) is suitable for retaining moisture from non-condensable gases. All the solid electrolyte particles dragged by the Oxygen (O 2 ) and Hydrogen (H 2 ), the water vapour that still continues accompanying these generated gases, as well as flashbacks attempting to enter the system, are retained in the silica filter (3.3), which is the last step of system condensation.
  • the fouled oxyhydrogen gas (HHO) leaves the device (1), or the set of devices (1), it previously passes through the coil section (3.1), with a view to liquefying the water vapour that accompanies the gas, and retaining it in the condensate chamber (3.2).
  • the silica filter (3.3) is provided, which retains the rest of the moisture and solids dragged by the oxyhydrogen gas (HHO) generated.
  • said device (s) (1) cool down, which produces a negative pressure coefficient that forces the entry, inversely, of flow of air through the silica filter (3.3) to compensate in balance with the outside atmospheric pressure, producing the return of the condensate accumulated in the condensate chamber (3.2) towards the cavity (1.11) of the shell (1) of the device (s) (1), also dragging with it the condensate existing in the coil section (3.1) and in the collector duct (4), said condensate being introduced into the cavity or cavities (1.11) through the corresponding gas outlet duct(s) (1.2) of the set of devices (1).
  • the silica filter (3.3) of the invention replaces the water bubbler used in known systems, where, due to the negative pressure coefficient that occurs when cooling the oxyhydrogen gas (HHO) generator of these known systems, the water content of the bubbler is sucked towards said generator, and with it, its flashback arrestor capacity is eliminated, making the use of these known systems very dangerous.
  • HHO oxyhydrogen gas
  • the chamber forming the silica filter (3.3) constitutes a safe space for combustion in the event of flashback.
  • said chamber filled with silica allows said detonation to develop in a safe and controlled manner, generating a vacuum and a discontinuity of the exit of the oxyhydrogen gas (HHO), which stops the flame, while the system does not stop producing said oxyhydrogen gas (HHO), whereby it is possible to immediately cut off possible flame propagation towards the inside of the device (1) or of the set of devices (1).
  • HHO oxyhydrogen gas
  • the silica filter (3.3) which constitutes a flashback arrestor, comprises two chambers, a lower one (3.31) that is hollow and empty, and an upper one (3.32) that houses a portion of silica (not shown in the figures).
  • This upper chamber (3.32) has a lower inlet protected by fibreglass and steel wool membranes (3.321) that pressure-retain the portion of silica inside it against a copper wire filter section (3.322), the latter, arranged at the upper outlet of the silica filter (3.3).
  • the copper wire filter section is provided as the last filtering step, with a view to retaining the microparticles released when the oxyhydrogen gas (HHO) passes through the silica in a dry state.
  • the collector duct (4) be connected to the condensate chamber (3.2) through a second duct (5), where the second duct (5) includes a solenoid valve (6) that can be actuated to equalise pressure between the devices (1) and the condensate chamber (3.2), when a sensor (not shown in the figures) detects that a maximum level of condensate is exceeded in the condensate chamber (3.2). Actuation of the solenoid valve (6), depending on the measurements made by the sensor, is commanded by the computer.
  • the pressure in the collector duct (4) is compensated with the pressure in the upper part of the condensate chamber (3.2), that is, the part arranged above the level of condensate in said chamber (3.2), letting the cold condensate stored in the condensate chamber (3.2) descend, which also drag the condensate existing in the coil section (3.1) and in the collector duct (4), said condensate being introduced into the cavity or cavities (1.11) through the corresponding gas outlet duct(s) (1.2) of the set of devices (1). All of which occurs without the device or set of devices (1) ceasing to operate, thanks to the effect of gravity, the principle of density and the principle of communicating vessels.
