Definitions

  • the invention relates to a method for the electrolytic preparation of an oxygen-containing and hydrogen-containing gas mixture, in which current is introduced into a liquid electrolysis medium via electrodes and oxygen gas and hydrogen gas are thus generated, which exit the electrolysis medium in at least partially mixed form as electrolysis gas.
  • electrolysis device for the electrolytic production of an oxygen-containing and hydrogen-containing gas mixture
  • the electrolysis device having at least one container for receiving electrolysis medium and having electrodes arranged therein for introducing current into the electrolysis medium.
  • water electrolysis water is converted from a liquid electrolysis medium into hydrogen gas and oxygen gas by introducing electricity. These gases rise from the electrodes as they form.
  • hydrogen and oxygen are mixed, oxyhydrogen, also HHO or Brownian gas, is formed, later called electrolysis gas.
  • This gas can be used well as a fuel, but it is highly explosive and flammable and therefore poses a safety hazard. Therefore, the hydrogen gas and oxygen gas are often separated immediately after generation to avoid mixing. However, more complex structures are necessary for this and it may not be possible to completely prevent partial mixing.
  • JP S63304093 A discloses a container in which a liquid containing hydrocarbons is stored. HHO gas is introduced into the container via a pipe 2 and passed through the liquid, whereby the gas is enriched.
  • the HHO gas is highly flammable and explosive before mixing.
  • US 2009/134041 A1 discloses an electrolysis device that provides HHO gas. It is envisaged that this HHO gas after the production of the Electrolysis device is discharged and fed into the cylinder of an internal combustion engine, with mixing with additional gas can be done in a carburetor. Here, too, there is a risk of explosion when conducting the pure HHO gas.
  • the object of the invention is to increase the safety of the electrolysis or the electrolysis device and still provide a gas mixture that can be readily utilized.
  • electrolysis gas is mixed with an additional gas, which comprises lower hydrocarbons, to form a gas mixture immediately after it emerges.
  • At least one inlet of the container is connected to an additional gas source for supplying the container with an additional gas comprising lower hydrocarbons.
  • the proportion of oxygen in the gas mixture is reduced. This greatly reduces the risk of explosion and makes it easy to handle the gas.
  • the hydrocarbons ensure that the resulting gas mixture is still combustible and can be used as a fuel.
  • the electrolysis gas--and of course also the unmixed oxygen gas and hydrogen gas that may still be present--from the liquid surface enters a gas chamber in which it is mixed with the additional gas.
  • the container has a gas chamber which borders on a liquid surface of the electrolysis medium when the container is filled with electrolysis medium as intended, and that the outlet is arranged on the gas chamber.
  • the inlet can also be located at the gas chamber. It can also be below the liquid level when the container is filled as intended during normal operation. Provision can also be made here for the mixing with the additional gas to begin before it emerges from the electrolysis medium. This can be achieved, for example, by introducing the additional gas into the electrolysis medium.
  • the additional gas is preferably itself combustible.
  • Combustibility means that the gas in question can continue to burn with a suitable supply of oxygen after suitable ignition without additional fuels being necessary.
  • the additional gas is not combustible on its own, but the gas mixture obtained from the method according to the invention is already combustible.
  • Lower hydrocarbons are understood to mean hydrocarbon compounds, preferably non-cyclic hydrocarbon compounds, particularly preferably alkanes, which have no more than seven carbon atoms. So, for example, methane, ethane, propane, butane or pentane etc. are included. This group can also include cyclic hydrocarbons and/or those with double bonds, for example alkenes or multiple bonds such as alkynes.
  • the additional gas preferably consists at least predominantly of lower hydrocarbons and particularly preferably at least 80% by volume of lower hydrocarbons. It can be a mixture of lower hydrocarbons, for example natural gas, or pure lower hydrocarbons such as methane, propane or butane.
  • Percent by volume or % by volume is understood to mean the percentage by volume of a part of a mixture of the total volume of the mixture. So it is % v/v.
  • the gases are mixed with one another in such a way that the resulting gas mixture has an oxygen content of at most 15% by volume, preferably at most 12% by volume, particularly preferably at most 10% by volume, and very particularly preferably at most 5% by volume %Vol%. This ensures that the gas mixture is non-explosive and safe to handle. Because the oxygen content largely determines how great the risk of explosion or ignition is.
  • the resulting gas mixture has an oxygen content of at least 2% by volume, preferably at least 3% by volume.
  • the oxygen content of the resulting gas mixture is particularly preferably between 3% by volume and 5% by volume.
  • the gases are mixed with one another in such a way that the resulting gas mixture has a proportion of lower hydrocarbons of at most 95% by volume, preferably at most 90% by volume, particularly preferably at most 85% by volume, and very particularly preferably at most 80%.
  • the additional gas is guided along the liquid level of the electrolysis medium. This means that the electrolysis gas and possibly still pure oxygen and/or hydrogen gas are mixed with the additional gas immediately after it emerges from the liquid. A particularly good mixture is achieved by guiding the additional gas along the surface.
  • the electrolysis takes place in at least one container, also an electrolysis container, in which the electrolysis medium is arranged and that the additional gas is introduced into a gas compartment above the liquid level of the electrolysis medium. In this way, mixing can take place directly upon exit.
  • the electrolysis takes place in a substantially gas-tight container and that additional gas is introduced into the container via at least one inlet and the gas mixture is discharged via at least one outlet and that preferably at least one inlet and at least one outlet at im Substantially opposite sides of the container are arranged.
  • Sufficient mixing can take place, in particular in the case of an opposite arrangement, without additional mixing devices such as fans, nozzles or flow obstacles being provided.
  • the opposing arrangement ensures that the additional gas flows in on one side, along the surface of the liquid, and flows out again via the outlet, with the mixing with the electrolysis gas taking place automatically as a result of passing through the surface of the liquid.
  • the container has at least one outlet for discharging the gas mixture and that preferably at least one outlet and at least one inlet are arranged on opposite sides of the container. It is important that they are arranged opposite one another in the plane of the liquid surface of the electrolysis medium so that the flow takes place along the surface.
  • the oxygen content and/or the hydrogen content of the gas mixture and/or the gas flow of the additional gas before mixing and/or the gas flow of the resulting gas mixture is measured and the amount of additional gas supplied and/or an electrical output used for the electrolysis is regulated as a function of the measured values.
  • This increases safety, since the risk of an explosive gas mixture forming can be prevented.
  • provision can be made for the electrolysis to be slowed down or switched off when the inflowing amount of additional gas falls below a limit value.
  • the amount of make-up gas is increased when the measured concentration of oxygen and/or hydrogen is too high.
  • this can be done with an upper limit value.
  • this can be done using a lower limit value.
  • the amount of additional gas in the gas mixture is measured, and the amount of additional gas supplied is regulated as a function of the measured values. What has just been said then also applies analogously.
  • the electrolysis device has at least one oxygen sensor and/or at least one hydrogen sensor in a gas compartment above the electrolysis medium, in the area of the outlet and/or downstream of the outlet and/or that the electrolysis device has in the area of the outlet and/or downstream of the Outlet and/or in the region of the inlet and/or upstream of the inlet has at least one flow meter for measuring the inflowing and/or outflowing amount of gas.
  • a control device for controlling the amount of additional gas flowing into the container, which is connected to the oxygen sensor and/or hydrogen sensor and/or at least one flow meter and is set up to determine the amount of additional gas as a function of the measured To regulate values of the oxygen sensor and/or hydrogen sensor and/or the measured gas flow.
  • the flow measurement is usually the measurement of the volume of gas transported per unit of time.
  • the electrolysis is switched off when a limit temperature of the electrolysis medium and/or the gas mixture is exceeded. This reduces the risk of self-ignition due to excessive operating temperatures.
  • at least one temperature sensor for measuring the temperature of the electrolysis medium and / or of the gas mixture is provided, and that the temperature sensor is set up to end the electrolysis when a limit temperature is exceeded, for example at 50 °C.
  • the electrolysis medium comprises water and that the electrolysis medium comprises at least one base and/or at least one acid and/or at least one salt, preferably sulfuric acid and/or potassium hydroxide and/or sodium sulfate.
  • electrolysis units are arranged in the container and the electrolysis units are electrically connected in parallel with one another, that each electrolysis unit has at least one cathode and at least one anode, each of which together in one Housing are arranged and that the electrolysis units are preferably independently controllable.
  • Independent controllability means that the amount of current introduced into the electrolysis units can be adjusted steplessly or in stages, or at least switched on and off, independently of the other units.
  • the housing of at least one, preferably all, electrolysis units has at least one, preferably two openings on a side facing the surface of the electrolysis medium, and at least one opening on a side facing away from the surface of the electrolysis medium, the electrolysis gas produced can escape via the at least an upper opening and fresh electrolysis medium can flow in via the at least one lower opening and a uniform flow can be achieved.
  • At least one, preferably 9, electrically conductive plates are arranged between at least one cathode and at least one anode of the electrolysis device, which are connected to one another and/or from the cathode and/or from the anode only via the electrolysis medium are electrically connected to one another and that this cathode is preferably designed as a cathode plate and this anode is designed as an anode plate.
  • the cathode plate, the anode plate and/or the electrically conductive plates are made of a metal or an alloy, in particular preferably made of a steel such as Nirosta steel. If several electrolysis units are provided, it is preferably provided that each electrolysis unit has at least one cathode plate and one anode plate. Investigations by the inventors have shown that such an embodiment is particularly advantageous and efficient.
