Definitions

  • the present invention relates to a control unit for controlling the temperature of a supplied with fluid via a line high-temperature electrolyzer.
  • High temperature electrolyzers typically require a suitable heat supply to reach the required operating temperatures.
  • High-temperature electrolysers take in the context of the present invention, the electrolytic decomposition of chemical compounds at temperatures that reach at least 200 ° C. However, these temperatures are preferably at least 350 ° C and most preferably at least 650 ° C.
  • high-temperature electrolyzers can be operated mainly on the basis of solid electrolyte cells, such as those in the EP12163588 are described.
  • the described therein high-temperature electrolyzer is supplied with a thermally conditioned gas stream, which supplies the solid electrolyte cells with sufficient thermal heat, so that they can be operated over a suitable temperature range for electrolysis.
  • the efficiency of the electrolysis process is significantly influenced in this case by the size of the heat input, since only at minimum temperatures to be reached in the interior of the cell required for an electrolysis ion fluxes can run in the solid electrolyte.
  • the required thermal heat can be supplied to it via the fluid, which is provided for the electrolytic conversion, or else via a further suitable process fluid supply.
  • the relevant fluid supply allows sufficient heat input.
  • this does not necessarily mean the entire required for the operation of heat by means of the fluid flow can be provided.
  • additional heat sources which can supply the high-temperature electrolyzer with a thermal heat contribution.
  • the specific current load of the electrolyte layer can be suitably increased, so that the ohmic losses lead to an advantageous heat release.
  • High-temperature electrolyzers can be operated under time-varying load and operating conditions. This in turn requires a suitable temporally varying supply of thermal heat to the high temperature electrolyzer. At the same time, varying amounts of fluid are sometimes electrochemically reacted in the variable load or operating conditions, so that a supply of varying amounts of supplied fluid must be guaranteed.
  • a high temperature electrolyzer may also be provided to remove surplus electricity from public power grids or directly from the power generator to convert the available electrical energy into a suitable form of chemical energy. Depending on the time supply of surplus electricity, the high-temperature electrolyzer should therefore be able to process time-varying amounts of fluid.
  • a high-temperature electrolyzer has different working conditions that make a temporally varying supply of thermal heat necessary.
  • an electrical energy receiving process step (charging step), as well as a chemical energy dispensing process step (discharge step) can be performed alternately to each other.
  • the electrical energy consuming process step is typically endothermic, thus requiring a supply of heat, then the chemical energy can be released Be process step exothermic, which either a lower heat input or even a derivative of the additional heat from the high-temperature electrolyzer is required.
  • both working states are made alternately with each other, an alternating supply of different amounts of heat and / or of fluid is required.
  • a high-temperature electrolyzer by a suitable control of the amount of heat or fluid quantity supplied to the high-temperature electrolyzer.
  • the high-temperature electrolyzer is provided, depending on the defined operating state, a predetermined amount of fluid to be reacted or a predetermined amount of thermal heat. If the high-temperature electrolyser operated, for example in a different working condition, a suitable intervention is made by means of the control, wherein the amount of heat or the amount of fluid is adapted to the new working condition. In such an adaptation, however, often shows that the high-temperature electrolyzer is either supplied after changing the working state only with insufficient amounts of thermal heat or experiences an oversupply of thermal heat.
  • a high thermal power loss can contribute to a lack of efficiency, since sometimes from the high-temperature electrolyzer thermal heat is dissipated unused to the environment. In particular, with frequent changes of the individual working conditions, the overall efficiency of the electrolysis process is so significantly reduced.
  • control unit for controlling the temperature of a supplied with fluid via a line high temperature electrolyzer, which avoids the known from the prior art disadvantages.
  • control unit should be suitable for ensuring a thermally efficient operation of the high-temperature electrolyzer.
  • control unit make it possible to reduce the thermal power dissipation during operation of the high-temperature electrolyzer or to completely avoid a loss of heat output.
  • control unit should ensure an operationally adapted temperature control of the high-temperature electrolyzer.
  • a control unit for controlling the temperature of a high-temperature electrolyzer supplied with fluid via a conduit, which has at least one temperature probe designed to detect the temperature at a location of the conduit and at least one in With respect to the high-temperature electrolyzer upstream of the line, the first conditioning unit physically condition the fluid, and a return line which returns fluid discharged from the high-temperature electrolyzer to a location of the conduit upstream of the high-temperature electrolyzer wherein the control unit controls the first conditioning unit as a function of the temperature detected by the temperature probe.
  • the line comprises both all areas of the fluid supply line as well as all areas of fluid discharge.
  • the return line is excluded.
  • the line should also encompass areas which are provided within the high-temperature electrolyzer for fluid conduction.
  • a detection of the temperature according to the invention comprises a detection of the temperature in or on the line. Also included here is also a detection that is not directly in or on the line, but also such detections that allow a conclusion on the temperature values or on temperature change values at these locations.
  • the control unit allows a suitable control of the first conditioning unit for physical conditioning of the high-temperature electrolyzer supplying fluid, while at the same time be ensured due to the return of the fluid to a location which is upstream with respect to the high-temperature electrolyzer, a total energy efficient operation can. Due to the recirculation of the fluid, it is above all possible for thermal heat, which would otherwise be lost after emerging from the high-temperature electrolyzer, to be transferred again to the fluid flow to be supplied to the high-temperature electrolyzer. At the same time, the temperature-controlled control allows the operating condition of the first conditioning unit connected to the line to be suitably adapted to the amount of thermal heat recirculated.
  • the high-temperature electrolyzer is operated with the release of chemical energy in an exothermic process step, then the heat contained in the high-temperature electrolyzer can be suitably re-used after the change of the working state by recycling. Consequently, less provision of external heat energy is required.
  • the first conditioning unit is designed, for example, as a heating device, which can apply an additional amount of heat to the fluid flow, the residual heat still remaining can be advantageously utilized by recycling the fluid flow leaving the high-temperature electrolyzer without unduly stressing the heating device.
  • a suitable adaptation of the size of the fluid flow can take place in which, for example, the return of the fluid emerging from the high-temperature electrolyzer the High-temperature electrolyzer to be supplied fluid stream is added.
  • changes in the mass flow which are required due to different working conditions, can be suitably compensated or adjusted, wherein a simultaneous thermal conditioning of the fluid flow can take place.
  • the fluid flow supplying the high-temperature electrolyzer is also changed with regard to its chemical composition, since a chemical change of the fluid can occur due to the chemical partial processes taking place in the high-temperature electrolyzer.
  • the fluid is, for example, air
  • this can be changed with regard to its composition, that is to say with regard to its partial pressures of the individual constituents. Accordingly, it is possible that air leaving a high-temperature electrolyzer has an increased amount of oxygen. By returning and mixing this air with the high-temperature electrolyzer supplying fresh air, consequently, the oxygen content can be suitably adjusted.
  • the efficiency of the electrochemical processes in the high-temperature electrolyzer can sometimes also be influenced, since these are concentration-dependent.
  • the arrangement of the at least one temperature probe is arranged in or on the line in the high-temperature electrolyzer. Accordingly, the temperature probe can detect the temperature condition directly in the reaction cell of the high-temperature electrolyzer, thereby enabling a good detection of the current reaction state.
  • the temperature value detected by the at least one temperature probe can be supplied to the control unit, which can suitably set the operating state of the at least one first conditioning unit.
  • the conditioning unit may in this case be designed so that they only affect the heat content of the fluid flow or also allowing simultaneous conditioning of the heat and mass flow of the fluid stream.
  • a suitable control of the operating state of the first conditioning unit is set as a function of the plurality of detected temperature values.
  • a control based on determined temperature difference values is advantageous.
  • a regulation of the at least one first conditioning unit takes place as a function of a detected temperature difference between at least two detected temperature values.
  • the two temperature values are in this case detected in particular by two different temperature probes. Accordingly, it is possible that the control unit does not process two different temperature values as control variables, but that they use only one controlled variable, namely the temperature difference value, as control parameters.
  • the temperature difference can be determined approximately advantageously by an electronic comparison circuit.
  • the return line returns the fluid discharged from the high-temperature electrolyzer to a heat exchanger which is connected to the line and which is designed to thermally condition the fluid in the line before it reaches high temperature Electrolyzer is supplied. Consequently, thermal heat can be appropriately extracted from the fluid discharged from the high-temperature electrolyzer, and the heat difference is transmitted to the fluid to be supplied to the high-temperature electrolyzer. As a result, thermal power dissipation is reduced due to inferred thermal heat in the exiting fluid.
  • the return line opens into the line and thus the in-line fluid is conditioned by recirculated fluid before both are fed to the high-temperature electrolyzer. Because of this recirculation of the fluid exiting the high temperature electrolyzer into the upstream conduit with respect to the high temperature electrolyzer, simultaneous thermal conditioning as well as mass flow conditioning of the total fluid flow to be supplied to the high temperature electrolyzer occurs. Consequently, not only is an increase in efficiency of the electrolysis operation achieved due to reduced thermal dissipation, but also the effective fluid consumption is improved. Due to the mixture of recirculated fluid, as well as not yet the high-temperature electrolyzer fluid supplied can also be carried out an advantageous fluid conditioning with respect to the chemical composition.
  • control unit controls the first conditioning unit in dependence of the temperatures detected by the temperature probes.
  • a control based on two different temperature values allows a targeted adjustment.
  • the change in temperature can be monitored better in the high-temperature electrolyser, thus ensuring improved conditioning of the fluid.
  • an embodiment in which the two temperature probes are mounted in or on the high-temperature electrolyzer is advantageous.

  • the further conditioning unit designed as a flow generator allows a suitable adaptation of the fluid flow in the conduit, whereby the high-temperature electrolyzer can be supplied with suitable quantities of fluid at different times.
  • the regulation of the further conditioning unit can also be adjusted to the recirculated quantities of fluid leaked from the high-temperature electrolyzer.
  • the further conditioning unit acts upon a fluid stream which is not further thermally conditioned and which is mixed with the recirculated thermally conditioned fluid stream. Due to the suitable flow adjustment, consequently, the total mass flow can advantageously be adjusted.
  • the flow generator is preferably designed as a fan when the fluid is a gas.
  • the at least one temperature probe is provided on the line at a first location upstream of the high temperature electrolyzer, and in particular another second temperature probe on the line at a second location downstream of the high temperature electrolyzer , Due to the temperature values that are determined at the two locations, a temperature profile within the high-temperature electrolyzer can be determined well. Et al Thus, by means of suitable assumptions, a good knowledge of the temperature gradient in the high-temperature electrolyzer and thus its operating state can be obtained.
  • the at least one temperature probe is provided on the line at a first location upstream of the high-temperature electrolyzer and in particular another second temperature probe is provided in or on the high-temperature electrolyzer.
  • the two independently recorded temperature values allow a good Knowledge of the temperature profile within the high-temperature electrolyzer.
  • the temperature values within the high-temperature electrolyzer are known through targeted temperature detection, a knowledge of the temperature distribution field within the high-temperature electrolyzer which is sufficiently good for most applications can be obtained.

Due to the knowledge of three independent temperature values, therefore, a very good knowledge of the temperature distribution field within the high-temperature electrolyzer can be obtained. This in turn makes it possible to make suitable assumptions with regard to the operating state of the high-temperature electrolyzer, which permit suitable regulation.
